Top 100 Vocabulary for Visiting and Touring EU | Aachen

You do not need to learn all one hundred entries at once. Choose a route, read its short lesson, then select five words that answer a question you genuinely have. Say each word, explain it without looking and use it in a new sentence. A smaller set used accurately is more valuable than a long list recognized only on sight.

Each entry includes an English pronunciation guide, a Simplified Chinese meaning, tone-marked pinyin, a definition, an example and a usage note. Pronunciation follows a broadly British English model; the respelling highlights the stressed syllable. Pinyin reads the Chinese expression, not the English headword. Proper names may have different local pronunciations.

All example sentences, conversations, model projects and practice passages in this guide are original hypothetical learning scenarios. They are not reports of actual encounters, historical events, museum displays, research findings or available services. The separately linked context below contains the sourced local facts. This distinction lets you practise freely while remaining careful about what you claim to know.

Before the words: eight useful Aachen connections

A border setting for connected learning

Aachen is in western Germany near the meeting area of Germany, Belgium and the Netherlands. Its location makes cross-border communication a useful theme for this guide. The official Aachen tourism site introduces that geographical setting. The language lessons here use it as a starting point; they do not assume that every local resident speaks the same languages or has the same experience of crossing a border.

A chapel within a changing cathedral

UNESCO identifies Charlemagne’s Palatine Chapel as the historic core of Aachen Cathedral. The octagonal core and later additions help explain why a building can contain several historical layers. The cathedral entered the World Heritage List in 1978. Read the UNESCO account of Aachen Cathedral for the architectural context. In your own writing, distinguish the original building phase from features added afterwards instead of calling everything equally ancient.

A throne and a limit to certainty

The cathedral’s own account says that identifying the imperial throne as Charlemagne’s personal throne cannot be established unequivocally. It records the first written mention in connection with Otto I’s coronation in 936. That is a useful lesson in evidence: an object’s strong association with a famous person does not settle every question about its use. See the cathedral’s imperial-throne history.

Thermal water without a safety assumption

The City of Aachen explains that local thermal water moves through deep rock formations before reaching the surface, acquiring heat and dissolved minerals along its route. This supports the vocabulary of groundwater and heat used below. It does not make any particular water source suitable for drinking or touching. The city’s thermal-water explanation is the local reference; follow current signs and responsible staff instructions at any real site.

Printen as a doorway into food language

Printen are a characteristic Aachen speciality. Local producer Bäckerei Mannebach describes them as spiced baked goods with beet syrup and discusses variations in their preparation. That producer’s Printen explanation is a useful example of craft language, rather than a specification for every product sold under the name. The baking chapter deliberately includes wider terms for comparing ingredients, tools, processes and labels.

Cooperation has practical language

The Euregio Meuse–Rhine organization brings together partner regions from Germany, Belgium and the Netherlands. Its organizational description identifies Dutch, French and German among the region’s languages and emphasizes cooperation across national boundaries. See the Euregio’s own description. This provides context for words such as counterpart and reciprocity, without implying that legal qualifications, tickets or administrative rules are automatically interchangeable.

Engineering connects ideas with tests

RWTH Aachen University’s research overview includes materials, modelling, production, energy and mobility-related work. These themes make Aachen a useful setting for language about models, forces and design decisions. The university’s research overview supplies the institutional connection. The classroom designs and experiments below are educational inventions, not descriptions of current university projects or an invitation to enter a laboratory.

Check access close to a real visit

As checked on 4 October 2026, the cathedral’s visitor page says that the choir and the upper area containing the imperial throne require a guided tour. It also warns that services and events can alter visitor access. Check the official cathedral visitor information again near your visit. A description of an object in this guide does not promise access to it on a particular day.

Historical vocabulary becomes easier when you separate people, powers and records. A courtier belongs to court life; a regent exercises authority for someone else; an emissary represents a sender on a mission. These roles can overlap in a story, but they are not interchangeable labels. Before choosing a noun, ask what the person is doing and where the authority comes from.

Written evidence needs the same care. An archivist preserves and organizes records, a chronicler records events, and a modern reader may prepare a transcription. A transcription can be accurate even when the original account is incomplete or biased. Copying words faithfully is a different task from proving that everything in those words happened exactly as described.

Try building a short chain: a ruler issues an edict, an office prepares copies, a messenger carries one, and a later historian reads the surviving record. Then ask where information could have been omitted, misunderstood or lost. The exercise creates a meaningful relationship between the words while avoiding unsupported claims about a particular historical event.

1. Aachen

Say it: /ˈɑːkən/ · AH-kuhn

中文: 亚琛 · Yàchēn

Meaning: A city in western Germany, close to Belgium and the Netherlands, known for its cathedral and thermal springs.

Example: Our class chose Aachen as the setting for a project connecting history, water and engineering.

中文: 宫廷礼拜堂 · gōngtíng lǐbàitáng

Meaning: A chapel belonging to a royal or imperial palace; here, the historic chapel within Aachen Cathedral.

Example: The student asked which parts of the Palatine Chapel belonged to the earliest building phase.

中文例句: 学生问宫廷礼拜堂的哪些部分属于最早的建造阶段。

Use it well: Palatine identifies a connection with a palace. The name explains the chapel’s original royal setting, not its present access arrangements.

4. Carolingian

Say it: /ˌkærəˈlɪndʒiən/ · ka-ruh-LIN-jee-uhn

中文: 加洛林王朝的 · Jiāluòlín wángcháo de

Meaning: Relating to the Frankish ruling dynasty associated with Charlemagne and its period of political and cultural influence.

Example: Our exhibition compared a Carolingian manuscript with a much later printed book.

中文: 朝臣 · cháochén

Meaning: A person who attends a ruler’s court, often serving the ruler or seeking influence there.

Example: In the story, a courtier waited outside the chamber before presenting a petition.

中文例句: 在这个故事中，一名朝臣在厅外等候，然后才呈上请愿书。

Use it well: The word describes a position within court life; it does not tell you whether the person was trustworthy.

6. regent

Say it: /ˈriːdʒənt/ · REE-juhnt

中文: 摄政者 · shèzhèngzhě

Meaning: A person who governs temporarily on behalf of a monarch who cannot exercise royal authority.

Example: The regent in the novel governed while the young monarch completed her education.

9. codify

Say it: /ˈkəʊdɪfaɪ/ · KOH-di-fy

中文: 编纂成典 · biānzuǎn chéng diǎn

Meaning: To arrange laws, rules or principles into a clear, systematic written form.

Example: The school committee decided to codify its competition rules so that every team received the same instructions.

中文例句: 学校委员会决定把比赛规则系统整理成文，让每支队伍收到相同的指示。

Use it well: Codifying rules organizes them; it does not necessarily mean inventing entirely new rules.

10. emissary

Say it: /ˈemɪsəri/ · EM-ih-suh-ree

中文: 使者 · shǐzhě

Meaning: A person sent to represent someone else and deliver a message or carry out a particular mission.

Example: In our role-play, the emissary brought a written proposal rather than an ultimatum.

中文例句: 在我们的角色扮演中，使者带来了一份书面提议，而不是最后通牒。

Use it well: The word is more formal than messenger and often suggests a diplomatic or political purpose.

11. heir apparent

Say it: /ˌeər əˈpærənt/ · air uh-PAIR-uhnt

中文: 确定继承人 · quèdìng jìchéngrén

Meaning: The person first in line to inherit a title whose place cannot be displaced by another person’s birth.

Example: The family-tree exercise asked us to distinguish the heir apparent from other possible successors.

中文例句: 家谱练习要求我们区分确定继承人与其他可能的继承者。

Use it well: The phrase has a technical succession meaning; an expected future company leader is a figurative use.

12. interregnum

中文: 君位空缺期 · jūnwèi kōngquē qī

Meaning: A period between one ruler’s reign and the next, or a gap between established governments.

Example: The imaginary timeline marked the interregnum in grey because no monarch held the throne during those months.

中文例句: 这条设想的时间线用灰色标出了君位空缺期，因为那几个月没有君主在位。

13. consort

Say it: /ˈkɒnsɔːt/ · KON-sort

中文: 君主配偶 · jūnzhǔ pèi’ǒu

Meaning: The spouse of a reigning monarch, especially when that spouse does not rule in their own right.

Example: The museum exercise asked whether the portrait showed a reigning queen or a royal consort.

中文例句: 博物馆练习要求判断画像中的人物是在位女王还是君主配偶。

Use it well: This noun stresses the first syllable. The related verb consort has a different meaning and stress pattern.

Say it: /ˈtʃɑːnsələri/ · CHARN-suh-luh-ree

中文: 大臣办公机构 · dàchén bàngōng jīgòu

Meaning: The office, staff or administrative department of a chancellor, historically often responsible for official documents.

Example: In the court scene, the chancellery prepared copies of the ruler’s correspondence.

中文例句: 在宫廷场景中，大臣办公机构准备了统治者往来信函的副本。

Use it well: Check the historical setting: offices and responsibilities differed between states and periods.

15. annals

Say it: /ˈænəlz/ · AN-uhlz

中文: 编年史 · biānniánshǐ

Meaning: Historical records arranged year by year, often recording important events in brief entries.

Example: The learner compared the annals with a modern account that explained causes as well as dates.

中文例句: 学习者把编年史与一篇既解释原因又列出日期的现代记述作比较。

Use it well: Usually plural, annals can also refer more broadly to the recorded history of a subject.

16. chronicler

Say it: /ˈkrɒnɪklə/ · KRON-ih-kluh

Example: The archivist in our story explained why the original letter needed careful handling.

中文例句: 我们故事中的档案管理员解释了为什么这封信的原件需要小心处理。

Use it well: An archivist manages records; the job is different from writing every historical interpretation of those records.

18. palaeography

Say it: /ˌpæliˈɒɡrəfi/ · pal-ee-OG-ruh-fee

中文: 古文字书写研究 · gǔwénzì shūxiě yánjiū

Meaning: The study of old handwriting and scripts, including how to read and date historical written material.

Example: She discovered that palaeography required patient comparison of letter shapes rather than quick guessing.

中文例句: 她发现，古文字书写研究需要耐心比较字母形状，而不是匆忙猜测。

Use it well: This concerns historical writing systems and handwriting; it is not the study of fossils.

19. codex

Say it: /ˈkəʊdeks/ · KOH-deks

中文: 古抄本 · gǔ chāoběn

Meaning: An early manuscript book made from separate leaves fastened together along one side, rather than a scroll.

Example: The display used a diagram to show how a codex could hold writing on both sides of each leaf.

中文例句: 展示用图解说明古抄本如何在每一叶的正反两面书写。

Use it well: The plural is codices. A codex is a physical book form, not simply any old piece of writing.

20. transcription

Say it: /trænˈskrɪpʃən/ · tran-SKRIP-shuhn

中文: 转录文本 · zhuǎnlù wénběn

Meaning: A written version made by copying another text or representing speech in writing.

Example: Before translating the letter, we checked our transcription against the photograph of the original.

中文例句: 在翻译这封信之前，我们把转录文本与原件照片进行了核对。

Use it well: Transcription records what is written or spoken; translation changes the language in which the meaning is expressed.

Back to all 100 words · Continue to the next chapter

This chapter moves from what you can notice to what you can explain. A smell, a warm surface or a pale deposit is an observation. An explanation might concern dissolved substances, heat transfer or groundwater movement. Keep those steps separate. You can describe an observation confidently while remaining uncertain about its cause, and that uncertainty can make your science writing more accurate.

Use units whenever you move from description to measurement. Warm is an everyday adjective; temperature is a measurable quantity. Fast flow is a broad impression; a flow rate states how much fluid passes during a defined time. Numbers become useful when the reader knows what was measured, which units were used and how the reading was obtained.

For safe practice, draw diagrams or use supplied data rather than touching, tasting or collecting unknown spring water. Label the surroundings as well as the object. Ambient temperature, container design and starting conditions help explain why two cooling curves may differ. A good account states the comparison fairly before trying to announce which result is better.

21. aquifer

Say it: /ˈækwɪfə/ · AK-wih-fuh

中文: 含水层 · hánshuǐcéng

Meaning: A body of permeable rock or sediment that can store and transmit groundwater.

Example: The classroom diagram showed an aquifer beneath the hillside, with arrows indicating groundwater movement.

中文例句: 课堂图示画出了山坡下的含水层，并用箭头表示地下水的流动。

Use it well: It is not necessarily an underground lake. Water can occupy connected pores or fractures within the material.

22. fissure

Say it: /ˈfɪʃə/ · FISH-uh

中文: 裂隙 · lièxì

Meaning: A long, narrow crack or opening, especially in rock or the ground.

Example: On the model, coloured water moved through a fissure rather than through the solid plastic beside it.

中文例句: 在模型上，有色水沿着一条裂隙流动，而不是穿过旁边的实心塑料。

Use it well: The example is a simplified model; real groundwater movement depends on the surrounding rock and connected openings.

23. bedrock

Say it: /ˈbedrɒk/ · BED-rok

中文: 基岩 · jīyán

Meaning: Solid rock beneath loose surface material such as soil, sand or gravel.

Example: Our sketch placed a thin layer of soil above the bedrock and labelled both separately.

中文例句: 我们的草图把一层薄土画在基岩上方，并分别标注了两者。

Use it well: Figuratively, the bedrock of an argument is its fundamental basis. Keep the literal and figurative senses clear.

24. water table

Say it: /ˈwɔːtə ˌteɪbəl/ · WOR-tuh TAY-buhl

中文: 地下水位 · dìxià shuǐwèi

Meaning: The upper surface of the zone where connected pores and fractures in the ground are saturated with water.

Example: The lesson compared how the water table might rise after a wet season and fall during a dry one.

中文例句: 这节课比较了地下水位在雨季后可能上升、在旱季期间可能下降的情况。

Use it well: The level can change. A drawing of it should not imply that all groundwater stays at one depth.

25. mineral deposit

Say it: /ˈmɪnərəl dɪˌpɒzɪt/ · MIN-uh-ruhl dih-POZ-it

中文: 矿物沉积物 · kuàngwù chénjīwù

Meaning: An accumulation of naturally occurring mineral material; here, material left behind as water conditions change.

Example: We drew the pale mineral deposit around the classroom kettle without guessing its exact chemical composition.

中文例句: 我们画下了教室水壶周围的浅色矿物沉积物，没有猜测其确切化学成分。

Use it well: In mining, the phrase can describe a concentrated mineral occurrence in the ground; context identifies the intended sense.

26. sulphurous

Say it: /ˈsʌlfərəs/ · SUL-fuh-ruhs

中文: 含硫的 · hánliú de

Meaning: Containing sulphur or its compounds, or having a smell associated with certain sulphur compounds.

Example: The travel note mentioned a sulphurous smell but made no claim about the water’s safety.

中文例句: 这则旅行笔记提到了硫化物气味，但没有声称水是安全的。

Use it well: Smell alone cannot identify a chemical mixture or establish whether water is safe to drink.

27. dissolved solids

Say it: /dɪˌzɒlvd ˈsɒlɪdz/ · dih-ZOLVD SOL-idz

中文: 溶解性固体 · róngjiěxìng gùtǐ

Meaning: Substances dissolved in water that remain as solid material when the water is removed under specified testing conditions.

Example: The report listed dissolved solids separately from the visible particles floating in the water sample.

中文例句: 报告把溶解性固体与水样中漂浮的可见颗粒分开列出。

Use it well: Clear-looking water can contain dissolved substances. Appearance is different from a laboratory measurement.

28. hydrothermal

Say it: /ˌhaɪdrəʊˈθɜːməl/ · hy-droh-THER-muhl

中文: 热液的 · rèyè de

Meaning: Relating to hot water within or beneath the Earth’s crust and the processes it causes.

Example: The science group used hydrothermal as a search term when researching how hot water interacts with rock.

中文例句: 科学小组在研究热水如何与岩石相互作用时，把“热液的”作为搜索词。

Use it well: The word describes a geological setting or process; it does not mean every warm cup of water.

29. convection current

Say it: /kənˈvekʃən ˌkʌrənt/ · kuhn-VEK-shuhn KUR-uhnt

中文: 对流 · duìliú

Meaning: A circulating movement in a fluid that transfers heat, often driven by temperature-related differences in density.

Example: In the supervised demonstration, a convection current carried the coloured water upward on the warmer side.

中文例句: 在有指导的演示中，对流使有色水沿着较热的一侧向上移动。

Use it well: Convection involves movement of a fluid. Do not confuse it with heat conducted through a stationary solid.

30. heat exchange

Say it: /ˈhiːt ɪksˌtʃeɪndʒ/ · HEET iks-CHAYNJ

中文: 热交换 · rè jiāohuàn

Meaning: The transfer of thermal energy between substances or systems at different temperatures.

Example: The diagram showed heat exchange between the warm pipe and the cooler water surrounding it.

中文例句: 图示展示了温热管道与周围较冷的水之间的热交换。

Use it well: A heat exchanger is a device; heat exchange is the transfer process that the device enables.

31. thermal conductivity

Say it: /ˌθɜːməl ˌkɒndʌkˈtɪvəti/ · THER-muhl kon-duk-TIV-ih-tee

中文: 导热率 · dǎorèlǜ

Meaning: A material property describing how readily heat passes through that material by conduction.

Example: We compared thermal conductivity when choosing between two materials for the handle of a container.

中文例句: 我们为一个容器选择把手材料时，比较了两种材料的导热率。

Use it well: A material with high thermal conductivity transfers heat readily; that is not the same as storing much heat.

32. heat retention

Say it: /ˈhiːt rɪˌtenʃən/ · HEET rih-TEN-shuhn

中文: 保温能力 · bǎowēn nénglì

Meaning: The ability of an object or system to keep thermal energy and remain warm for a period.

Example: The class compared heat retention by recording how quickly water cooled in two covered containers.

中文例句: 全班通过记录两个有盖容器中的水冷却得多快，来比较它们的保温能力。

Use it well: State the test conditions. Container shape, insulation and starting temperature can all affect the comparison.

33. thermal equilibrium

Say it: /ˌθɜːməl ˌiːkwɪˈlɪbriəm/ · THER-muhl ee-kwih-LIB-ree-uhm

中文: 热平衡 · rè pínghéng

Meaning: A condition in which bodies in thermal contact have the same temperature and no net heat flows between them.

Example: Our idealized example reached thermal equilibrium when the two objects had the same temperature.

中文例句: 在我们的理想化示例中，两个物体温度相同时就达到了热平衡。

Use it well: The word net matters: the definition concerns the overall transfer of heat between the bodies.

34. scalding

Say it: /ˈskɔːldɪŋ/ · SKAWL-ding

中文: 滚烫的 · gǔntàng de

Meaning: Hot enough, especially as a liquid or vapour, to cause a burn.

Example: A warning in the imaginary experiment reminded pupils that scalding water must be handled only by the supervisor.

中文例句: 设想实验中的警告提醒学生，滚烫的水只能由指导人员处理。

Use it well: This is a strong safety word, not a precise temperature measurement. Never test unknown hot water by touch.

35. lukewarm

Say it: /ˌluːkˈwɔːm/ · look-WORM

中文: 微温的 · wēiwēn de

Meaning: Slightly warm, with a temperature that feels neither distinctly hot nor cold.

Example: By the time the traveller returned to the table, the tea was lukewarm.

中文例句: 旅行者回到桌边时，茶已经微温了。

Use it well: In figurative use, a lukewarm response shows little enthusiasm. Context separates temperature from attitude.

36. cooling rate

Say it: /ˈkuːlɪŋ reɪt/ · KOO-ling rayt

中文: 冷却速率 · lěngquè sùlǜ

Meaning: The amount by which temperature decreases during a given period of time.

Example: The graph showed a faster cooling rate at the start and a slower change later.

中文例句: 图表显示，开始时的冷却速率较快，后来变化较慢。

Use it well: Include a time interval and temperature units when making a numerical claim about a rate.

37. ambient temperature

Say it: /ˌæmbiənt ˈtemprətʃə/ · AM-bee-uhnt TEM-pruh-chuh

中文: 环境温度 · huánjìng wēndù

Meaning: The temperature of the surrounding air or other immediate environment.

Example: We recorded the ambient temperature before comparing the two containers so that the room conditions were clear.

中文例句: 在比较两个容器之前，我们记录了环境温度，以便明确室内条件。

Use it well: Ambient describes the surroundings; it is not automatically the same as the temperature inside the object.

38. water sample

Say it: /ˈwɔːtə ˌsɑːmpəl/ · WOR-tuh SAM-puhl

中文: 水样 · shuǐyàng

Meaning: A small quantity of water collected to represent a source or to undergo examination or testing.

Example: The labelled water sample came with a collection time and location rather than an unsupported claim of purity.

中文例句: 贴有标签的水样附有采集时间与地点，而不是毫无依据的纯净声明。

Use it well: A sample needs context. Poor collection or storage can make later measurements misleading.

39. potable

Say it: /ˈpəʊtəbəl/ · POH-tuh-buhl

中文: 可饮用的 · kě yǐnyòng de

Meaning: Suitable and safe for people to drink according to the relevant water-quality requirements.

Example: The visitor asked where potable water was available instead of assuming that every fountain supplied drinking water.

中文例句: 访客询问哪里有可饮用的水，而没有认为每座喷泉都提供饮用水。

Use it well: This word is about drinking suitability. It does not follow from water being clear, natural or warm.

40. flow rate

Say it: /ˈfləʊ reɪt/ · FLOH rayt

中文: 流量 · liúliàng

Meaning: The quantity of a fluid passing a point during a specified time, often measured as volume per second.

Example: The team calculated the flow rate from the collected volume and the time shown on the stopwatch.

中文例句: 小组根据收集到的体积与秒表显示的时间计算了流量。

Use it well: State whether you mean volume flow or mass flow; the units should match the quantity measured.

Back to all 100 words · Continue to the next chapter

Food writing can do more than call something delicious. It can identify an ingredient, explain a production step, compare a label or describe the function of a tool. Start with the question you want to answer. Is the writer explaining how dough is handled, how a sweetener is produced or how packaged products can be compared? Choosing that purpose keeps the vocabulary useful.

Tools and processes belong in different grammatical positions. A baker uses a bench scraper, places dough on a baking sheet and watches a mixture crystallize. An ingredient can support a process without being the process itself. Leavening, for example, describes what happens as dough or batter rises; a raising agent is something added to help bring that about.

Comparison also needs a common basis. Two nutrition labels may use different serving sizes, so a quick glance at the largest number can mislead. Name the reference quantity before comparing sugar content. If an ingredient or safety detail matters, ask about that detail directly rather than guessing from colour, smell, a traditional product name or an attractive packet.

41. Printen

Say it: /ˈprɪntən/ · PRINT-uhn, an English approximation

中文: 亚琛香料饼干 · Yàchēn xiāngliào bǐnggān

Meaning: Spiced baked sweets associated with Aachen, available in different textures and finishes rather than one universal recipe.

Example: The shopper compared two packets of Printen and checked each label before choosing a gift.

中文例句: 购物者比较了两包亚琛香料饼干，并在挑选礼物之前查看了每包的标签。

Use it well: Printen is the German plural name. Do not infer a particular ingredient list from the product name alone.

42. leavening

Say it: /ˈlevənɪŋ/ · LEV-uh-ning

中文: 膨松作用 · péngsōng zuòyòng

Meaning: The process of making dough or batter rise through the production, incorporation or expansion of gas.

Example: The recipe discussion focused on leavening because the two mixtures expanded differently in the oven.

中文例句: 食谱讨论重点关注膨松作用，因为两种混合物在烤箱中的膨胀情况不同。

Use it well: Leavening names the process here. A raising agent is an ingredient used to bring about that process.

43. cane syrup

Say it: /ˈkeɪn ˌsɪrəp/ · KAYN SIR-uhp

中文: 甘蔗糖浆 · gānzhe tángjiāng

Meaning: A thick, sweet liquid made by concentrating juice from sugar cane.

Example: The student compared cane syrup with another sweetener without assuming that both came from the same crop.

中文例句: 学生把甘蔗糖浆与另一种甜味料作比较，没有认为两者来自同一种作物。

Use it well: This is a general ingredient term, not a claim that every variety of Printen contains it.

44. sugar beet

Say it: /ˈʃʊɡə biːt/ · SHUUG-uh beet

中文: 糖用甜菜 · tángyòng tiáncài

Meaning: A root crop cultivated for the sugar contained in its enlarged root.

Example: A drawing of sugar beet helped the class connect a familiar ingredient with the plant that produced it.

中文例句: 一幅糖用甜菜的图画帮助全班把熟悉的食材与生产它的植物联系起来。

Use it well: Sugar beet and sugar cane are different crops, even though both can be used to produce sugar.

45. aniseed

Say it: /ˈænɪsiːd/ · AN-ih-seed

中文: 洋茴香籽 · yánghuíxiāngzǐ

Meaning: The small seed-like fruit of the anise plant, used as a spice with a liquorice-like flavour.

Example: In the tasting lesson, the teacher passed around a closed jar of aniseed for pupils to identify by its label.

中文例句: 在品味课上，老师传递了一罐盖好的洋茴香籽，让学生通过标签来辨认。

Use it well: Aniseed and star anise come from different plants. A similar flavour does not make them the same ingredient.

46. ground spices

Say it: /ˌɡraʊnd ˈspaɪsɪz/ · grownd SPY-siz

中文: 香料粉 · xiāngliào fěn

Meaning: Spices reduced to small particles or powder by grinding, rather than left whole.

Example: We measured the ground spices separately so that one strong flavour would not overwhelm the biscuit mixture.

中文例句: 我们分别量取香料粉，以免一种浓烈的味道盖过饼干混合物中的其他味道。

Use it well: Ground is the past participle of grind here; it does not refer to soil.

47. dough hook

Say it: /ˈdəʊ hʊk/ · DOH huuk

中文: 和面钩 · huómiàn gōu

Meaning: A curved attachment on a food mixer designed to mix and knead dough.

Example: In the equipment diagram, the dough hook was labelled separately from the whisk and the flat beater.

中文例句: 在设备图中，和面钩与打蛋器、平面搅拌桨分别标注。

The most useful language in an unfamiliar setting often repairs a misunderstanding. You can paraphrase an instruction, ask which date someone means or repeat a key detail in simpler words. These moves help both speakers. They also show that clear communication is a shared activity rather than a test in which one person must produce perfect sentences immediately.

A word that looks familiar in another language deserves attention, not automatic trust. A false friend may resemble an English word while meaning something different. A literal translation may reproduce the original structure yet sound unnatural or change the effect. Read the whole sentence and ask what the speaker is trying to accomplish before choosing your interpretation.

For group work, separate shared aims from remaining disagreements. Common ground can exist before consensus does. A compromise may resolve one practical issue while leaving a wider question open. When you explain a decision, name the parties, describe the issue and show what each agreed to do. Avoid claiming universal agreement merely because nobody spoke during a hurried meeting.

61. borderland

Say it: /ˈbɔːdəlænd/ · BOR-duh-land

中文: 边境地区 · biānjìng dìqū

Meaning: An area close to the boundary between countries or regions, often shaped by contact across that boundary.

Example: The interview asked a cross-border worker how commuting affected the family’s daily routine.

中文例句: 这次访谈询问一位跨境工作者，通勤如何影响家庭的日常安排。

Use it well: This general description does not establish a person’s legal, tax or social-security status under a particular country’s rules.

63. mutual recognition

Say it: /ˌmjuːtʃuəl ˌrekəɡˈnɪʃən/ · MYOO-choo-uhl rek-uhg-NISH-uhn

中文: 相互认可 · xiānghù rènkě

Meaning: An arrangement in which different authorities or organizations accept specified decisions, qualifications or standards from one another.

Example: The discussion asked whether mutual recognition applied to the qualification being considered, rather than assuming automatic acceptance.

中文例句: 讨论询问相互认可是否适用于所考虑的资格，而没有假定它会被自动接受。

68. literal translation

Say it: /ˌlɪtərəl trænsˈleɪʃən/ · LIT-uh-ruhl tranz-LAY-shuhn

中文: 直译 · zhíyì

Meaning: A translation that follows the words or structure of the source closely rather than freely expressing the intended meaning.

Example: A literal translation of the sign sounded awkward, so we checked what action the notice actually required.

Say it: /ˈtɜːn ˌteɪkɪŋ/ · TERN TAY-king

中文: 轮流发言 · lúnliú fāyán

Meaning: The way speakers organize who speaks next and when each person contributes to a conversation.

Example: Clear turn-taking gave the quieter members time to explain their ideas before the group made a decision.

中文例句: 明确的轮流发言安排让较安静的成员有时间在小组作决定之前解释自己的想法。

Use it well: Good conversation involves listening and responding, not merely waiting for a chance to deliver a memorized sentence.

74. common ground

Say it: /ˌkɒmən ˈɡraʊnd/ · kom-uhn GROWND

中文: 共同点 · gòngtóngdiǎn

Engineering vocabulary helps you explain why a design might work, how you would check it and what could make it fail. A numerical model is useful because it makes relationships explicit, but its results depend on the inputs and assumptions. A careful explanation connects the model with measurements rather than treating a computer-generated number as proof.

The words for forces and materials answer different questions. A tensile force pulls; a compressive force pushes. Strain concerns a relative change in dimensions, while an elastic limit identifies a boundary beyond which permanent deformation can remain. Use a labelled drawing to make these relationships visible. A precise diagram can reduce the need for a long, confusing sentence.

A design discussion also involves choices. Better manufacturability may require a simpler shape. A lighter component may introduce a trade-off elsewhere. Quality assurance concerns the process that gives confidence in consistent results, while one inspection tells you something narrower. Explain the requirement first, then the proposed test, and finally the evidence that would justify accepting or revising the design.

81. applied science

Say it: /əˌplaɪd ˈsaɪəns/ · uh-PLYD SY-uhns

中文: 应用科学 · yìngyòng kēxué

Meaning: The use of scientific knowledge and methods to solve practical problems or develop useful technologies.

Example: Our numerical model predicted a temperature change, but we still needed measurements to assess how well it matched reality.

中文例句: 我们的数值模型预测了温度变化，但我们仍需要测量数据来评估它与实际情况有多吻合。

Use it well: A model is a simplified representation. A detailed calculation can still be wrong if its assumptions are unsuitable.

83. scale factor

Say it: /ˈskeɪl ˌfæktə/ · SKAYL FAK-tuh

中文: 比例因子 · bǐlì yīnzǐ

Meaning: The number by which corresponding lengths or other specified quantities are multiplied when a representation is resized.

Example: We used a scale factor of two to double every length in the drawing without changing its proportions.

中文例句: 我们使用数值为二的比例因子，把图中每个长度都加倍，同时保持比例不变。

Use it well: For similar shapes, doubling lengths multiplies areas by four and volumes by eight; identify which quantity is being scaled.

Use it well: Force is a load, measured in newtons. Compressive strength is a material’s resistance to failure under compressive stress.

86. tensile force

Say it: /ˌtensaɪl ˈfɔːs/ · TEN-syl FORSS

中文: 拉伸力 · lāshēnlì

Meaning: A force that pulls on a material or structural part, tending to stretch it.

Example: The demonstration used a cord to show how tensile force acts along a stretched connection.

中文例句: 演示用一根绳子说明拉伸力如何沿着绷紧的连接作用。

Use it well: Tensile force pulls; compressive force pushes. Real structures can experience several kinds of loading at once.

89. strain gauge

Say it: /ˈstreɪn ɡeɪdʒ/ · STRAYN gayj

中文: 应变计 · yìngbiànjì

Meaning: A sensor used to measure small changes in the dimensions of an object under load, commonly through electrical resistance changes.

Example: The engineer attached a strain gauge to the test piece and checked the signal before applying the load.

中文例句: 工程师把应变计安装在试件上，并在施加载荷之前检查了信号。

Use it well: Strain describes relative deformation; it is different from the force or stress that may produce it.

Use it well: A design can work in principle yet be difficult to make repeatedly at the required quality and cost.

92. failure mode

Say it: /ˈfeɪljə məʊd/ · FAYL-yuh mohd

中文: 失效模式 · shīxiào móshì

Meaning: The particular way in which a component, product or process stops performing its intended function.

Example: The team identified a loose connection as one possible failure mode before discussing how to test for it.

中文例句: 小组先把连接松动确定为一种可能的失效模式，再讨论如何检测它。

Use it well: A mode describes how failure appears; a cause explains why it happens. The two should not be treated as identical.

93. non-destructive testing

Say it: /ˌnɒn dɪˈstrʌktɪv ˌtestɪŋ/ · non dih-STRUK-tiv TES-ting

中文: 无损检测 · wúsǔn jiǎncè

Meaning: Methods of examining materials or components for properties or defects without destroying their ability to be used as intended.

Example: The presentation compared non-destructive testing with a test that deliberately broke a sample to measure its limits.

中文例句: 演示把无损检测与一种故意破坏样品以测量其极限的测试作了比较。

Use it well: No single method reveals every defect. The suitable technique depends on the material, geometry and question.

94. quality assurance

Say it: /ˌkwɒləti əˈʃʊərəns/ · KWOL-ih-tee uh-SHOOR-uhns

中文: 质量保证 · zhìliàng bǎozhèng

中文例句: 学习者把边缘当作零刻度时，一把端部损坏的尺子引入了测量误差。

Use it well: The true value may be unknown in practice. Error and uncertainty are connected concepts, but they are not interchangeable labels.

96. sample size

Say it: /ˈsɑːmpəl saɪz/ · SAM-puhl syz

中文: 样本量 · yàngběnliàng

Meaning: The number of observations, participants or items included in a sample used for an investigation.

Example: The class increased the sample size from three components to twelve before comparing the two designs.

中文例句: 全班把样本量从三个零件增加到十二个，然后才比较两种设计。

Use it well: A larger sample does not fix biased selection or poor measurements. Explain how the sample was chosen as well.

97. feasibility

Say it: /ˌfiːzəˈbɪləti/ · fee-zuh-BIL-ih-tee

中文: 可行性 · kěxíng xìng

Meaning: The extent to which a proposed action or project can realistically be carried out under the relevant conditions.

Example: We assessed feasibility by checking materials, time, skills and space before promising to build the model.

中文例句: 在承诺制作模型之前，我们通过检查材料、时间、技能与空间来评估可行性。

Use it well: Feasible means practicable; it does not automatically mean desirable, affordable in every case or the best available option.

98. trade-off

Say it: /ˈtreɪd ɒf/ · TRAYD off

中文: 权衡 · quánhéng

Meaning: A situation in which improving one desirable feature involves accepting a disadvantage or reduction in another.

Example: The team explained the trade-off between a lighter casing and the additional reinforcement it might require.

中文例句: 小组解释了较轻的外壳与它可能需要的额外加固之间的权衡。

Use it well: Name both sides and explain their relationship. A list of unrelated advantages and disadvantages is less informative.

Say it: /rəʊˈbʌstnəs/ · roh-BUST-nuhs

中文: 稳健性 · wěnjiàn xìng

Meaning: The ability of a system, method or design to keep performing acceptably when conditions vary or disturbances occur.

Example: We tested robustness by changing the input slightly and checking whether the model’s main conclusion still held.

中文例句: 我们通过略微改变输入并检查模型的主要结论是否仍然成立，来测试稳健性。

Use it well: Specify the variation being tested. A design can be robust to one disturbance yet vulnerable to another.

100. remanufacture

Say it: /ˌriːmænjʊˈfæktʃə/ · ree-man-yoo-FAK-chuh

中文: 再制造 · zài zhìzào

Meaning: To rebuild a used product through a controlled process so that it meets a defined performance and quality standard.

Example: The proposal asked whether the company could remanufacture the returned units instead of making every part from new material.

中文例句: 提议询问公司是否可以对退回的产品进行再制造，而不是用新材料制造每个零件。

Use it well: Remanufacturing usually involves systematic inspection, restoration and testing; it is more specific than simply repairing one fault.

Build a paragraph from observation to explanation

Begin with this deliberately weak sentence: “The water was strange and the experiment was good.” It gives a reaction but little information. To improve it, identify the observable feature, the measurement or comparison, and the limit of what you know. Choose only terms that help answer those questions. Adding more technical vocabulary without adding evidence would leave the weakness unchanged.

Here is a stronger model: “We compared the cooling rate of water in two covered containers. Both samples began at the same temperature, and we recorded the ambient temperature before starting. The insulated container retained heat for longer under these test conditions. However, our small sample size means that we should repeat the comparison before making a broader claim.”

The revised paragraph works because each sentence has a job. The opening names the investigation. The second makes the comparison more transparent. The third reports a bounded result, and the last identifies a limitation. Notice that the passage does not claim to explain every possible difference between containers. It says enough to show what was tested and what remains uncertain.

Turn a historical label into a careful question

Imagine that a display caption links an old document with a royal court. Instead of writing “This proves that everyone obeyed the ruler,” ask what the document can actually show. Is it an edict, a later transcription or a chronicler’s account? Does it record an instruction, describe compliance or merely preserve what one writer believed? Those distinctions shape the question you should ask next.

A useful practice paragraph might read: “The transcription records an edict about trade, but the surviving text does not tell us how consistently the rule was followed. A chronicler might describe a public response, although that account would also need to be considered in context. I would look for another kind of record before concluding that the order changed everyday behaviour.”

The paragraph avoids pretending that one document answers every question. It also uses ordinary connecting language alongside the specialist words. But marks a limit, although introduces a qualification, and before explains a condition for the next judgement. Learn those connections as carefully as the nouns: they turn a word collection into reasoning.

Repair a misunderstanding politely

Practise this exchange with a partner. Visitor: “When you say the session is next Friday, do you mean the tenth or the seventeenth?” Coordinator: “I mean the seventeenth.” Visitor: “Thank you. Let me paraphrase the plan: we meet on the seventeenth, and you will confirm the room later.” The speaker checks the uncertain detail without accusing the other person of being unclear.

Now change the problem. Replace the date with a meeting point, the meaning of a label or which group is responsible for bringing materials. Keep the sequence: identify the ambiguity, ask one focused question, then confirm the answer. Do not add new commitments while paraphrasing. A clarification should preserve the agreed meaning rather than quietly expanding the plan.

Compare two proposals without declaring a premature winner

Your school design team has two container proposals. One is lighter; the other appears easier to manufacture. Write four sentences using feasibility, manufacturability, trade-off and robustness. Begin by stating the intended use. Then identify the comparison you can already make and the test you still need. This keeps a preference from being mistaken for a completed evaluation.

One possible response is: “We are designing a container for repeated classroom use. The simpler shape may improve manufacturability, but we need to assess feasibility using the materials and equipment available. The lighter design involves a trade-off if it needs extra reinforcement. We will compare robustness under the same defined handling conditions before choosing between the proposals.”

The words may and if are doing important work. They show that a relationship is being investigated rather than presented as an established result. You can still make a recommendation, but explain whether it rests on observations, calculations or an assumption. A recommendation with a visible reason is easier for another person to discuss and improve.

A short retrieval routine that checks meaning

Choose five entries from different chapters. Cover the definitions and explain each headword in plain English. Then reveal the definition and check the essential idea, rather than whether you repeated the exact wording. If you can only recall the Chinese translation, build a fresh English example before moving on. Understanding should survive a change of sentence.

On a second pass, connect two words without forcing an unnatural relationship. An archivist may check a transcription; a team may discuss a trade-off; a nutrition label may state sugar content. Explain why the pair belongs together. Next, choose a misleading pairing and correct it, such as treating a sample size as a temperature or calling every disagreement a lack of common ground.

Finish by writing a short travel-learning journal of about one hundred and fifty words. Choose one Aachen theme, add two sourced local facts from the context section, and clearly separate them from your own questions or imagined scenes. Use six to eight new headwords naturally. Review each one for meaning, grammar and relevance, then remove any word that adds difficulty without adding information.

For a parent or teacher: respond to the idea first

When reviewing a learner’s paragraph, begin by asking what the learner wanted the reader to understand. Praise is most useful when it identifies a specific choice, such as a well-explained comparison or a question that catches an ambiguity. Then choose one correction with a clear reason. A long list of disconnected vocabulary corrections can hide the central learning point.

If the writing is technically ambitious but difficult to follow, ask the learner to explain it aloud in simpler English. Keep the accurate idea, then rebuild the sentence around it. If the writing is clear but vague, ask for one more precise detail or a better-supported distinction. The next step should follow the actual difficulty, rather than assuming that every learner needs harder words.
