2. Common Chemistry Vocabulary for Speaking and Listening | 口语与听力常用化学词汇
Building a strong vocabulary is the first step to sounding like a confident chemist. Below is a table of terms you will often need, along with a pronunciation guide and meaning. Practise saying each word aloud until it feels natural.
建立扎实的词汇基础是让自己听起来像一位自信化学家的第一步。以下是你经常需要使用的术语表格，配有发音指南和释义。大声练习每个单词，直到感觉自然。
| Term | Pronunciation | Meaning |
|---|---|---|
| atom | /ˈætəm/ (AT-uhm) | Smallest part of an element |
| molecule | /ˈmɒlɪkjuːl/ (MOL-i-kyool) | Two or more atoms bonded together |
| element | /ˈelɪmənt/ (EL-i-muhnt) | Pure substance made of one type of atom |
| compound | /ˈkɒmpaʊnd/ (KOM-pownd) | Substance formed from two or more elements chemically joined |
| solution | /səˈluːʃən/ (suh-LOO-shuhn) | A mixture where a solute dissolves in a solvent |
| precipitate | /prɪˈsɪpɪteɪt/ (pri-SIP-i-tayt) | Insoluble solid formed in a reaction |
| neutralisation | /ˌnjuːtrəlaɪˈzeɪʃən/ (NYOO-truh-ly-ZAY-shuhn) | Reaction between an acid and a base to form salt and water |
As you listen to questions in your exam, you will need to quickly recognise these words. When speaking, using them accurately shows that you understand the science at a deeper level.
当你在考试中听问题时，需要快速识别这些单词。在表达时准确使用它们，能表明你对科学有更深层次的理解。
3. Describing States of Matter and Changes | 描述物质状态及其变化
You must be able to talk clearly about the three states of matter – solid, liquid and gas – and the changes between them. Use phrases like 'the particles are closely packed in a regular arrangement' for solids, or 'the particles move freely and are far apart' for gases.
你必须能够清楚地谈论物质的三态——固态、液态和气态——以及它们之间的变化。描述固体时使用“粒子紧密排列成规则结构”等表达，描述气体时使用“粒子自由运动且相距很远”等表达。
When explaining melting or boiling, mention that energy is transferred to the substance and the particles overcome the forces holding them together. For example: 'As ice melts, the water molecules gain enough energy to break free from their fixed positions, turning into a liquid.'
解释熔化或沸腾时，要提到能量传递给物质，粒子克服了它们之间的作用力。例如：“冰融化时，水分子获得足够的能量，摆脱了固定的位置，转变为液态。”
Listening tasks may involve a description of a heating curve. Be prepared to identify the plateaus where temperature remains constant as a change of state occurs, such as at 0 °C for melting ice or 100 °C for boiling water.
听力任务可能涉及对加热曲线的描述。要学会识别温度保持不变的平台段，这时正发生物态变化，例如冰在 0 °C 融化或水在 100 °C 沸腾。
4. Explaining the pH Scale and Neutralisation | 解释 pH 值及中和反应
The pH scale runs from 0 to 14. You need to be able to say that values below 7 are acidic, 7 is neutral, and values above 7 are alkaline. Use the terms 'hydrogen ions (H⁺)' for acids and 'hydroxide ions (OH⁻)' for alkalis.
pH 值的范围是 0 到 14。你需要能够说出：数值低于 7 为酸性，7 为中性，高于 7 为碱性。并正确使用“氢离子 (H⁺)”表示酸性、“氢氧根离子 (OH⁻)”表示碱性。
When describing neutralisation, say: ' H⁺ ions from the acid combine with the OH⁻ ions from the alkali to produce H₂O molecules.' Use the example HCl + NaOH → NaCl + H₂O.
描述中和反应时可以这样说：“在中和反应中，酸与碱反应生成盐和水。来自酸的 H⁺ 离子与来自碱的 OH⁻ 离子结合生成 H₂O 分子。”可举例 HCl + NaOH → NaCl + H₂O。
In a listening exam, you might hear a description of an indicator changing colour. Be familiar with the colours of universal indicator in strong acid (red), weak acid (orange/yellow), neutral (green), weak alkali (blue) and strong alkali (purple).
在听力考试中，你可能会听到指示剂颜色变化的描述。要熟悉通用指示剂在强酸（红）、弱酸（橙/黄）、中性（绿）、弱碱（蓝）和强碱（紫）中的颜色。
5. Discussing Periodic Table Trends and Elements | 讨论元素周期表趋势及元素
You may be asked to talk about an element's position in the periodic table. Practise saying: 'Elements are arranged in order of increasing atomic number. Metals are on the left side, and non-metals are on the right.' You can also mention groups and periods.
你可能需要谈论某个元素在周期表中的位置。练习这样的表达：“元素按照原子序数递增的顺序排列。金属在左侧，非金属在右侧。”你还可以提到族和周期。
Describe Group 1 elements (alkali metals) as very reactive, soft metals that react vigorously with water, producing hydrogen gas and an alkaline hydroxide. Use lithium (Li), sodium (Na) and potassium (K) as examples. The reaction gets more vigorous down the group.
描述第 1 族元素（碱金属）为非常活泼的软金属，与水剧烈反应生成氢气和碱性氢氧化物。可举锂 (Li)、钠 (Na) 和钾 (K) 的例子。沿族往下反应越来越剧烈。
For listening, you might hear about trends such as the increasing reactivity of Group 7 (halogens) going up the group. Be ready to recognise words like 'displacement reaction' and 'diatomic molecule', for example Cl₂.
在听力中，你可能会听到关于趋势的描述，如第 7 族（卤素）从下往上反应性增强。要能识别“置换反应”和“双原子分子”等词汇，例如 Cl₂。
6. Listening to Lab Safety Instructions | 听力理解实验室安全说明
Safety is a key topic in any chemistry exam. You will likely hear phrases like 'wear safety goggles', 'tie back long hair', 'use a fume cupboard for toxic gases', and 'handle acids with care'. Listen for keywords that tell you what to do, where to do it and why.
安全是所有化学考试中的关键话题。你可能会听到“戴上护目镜”、“把长发扎起来”、“在通风橱里处理有毒气体”和“小心处理酸”等短语。听时要抓住告诉你做什么、在哪里做以及为什么这样做的关键词。
When you are asked to speak about safety, structure your answer logically. Start by identifying the hazard, then state the precaution and the reason. Example: 'We must wear eye protection because hydrochloric acid is corrosive and could damage our eyes if splashed.'
当要求你谈论安全时，要有逻辑地组织回答。先指出危险，然后说明预防措施和理由。例如：“我们必须佩戴护目镜，因为盐酸具有腐蚀性，一旦溅入眼睛可能会造成伤害。”
Listening comprehension exercises often use lab scenarios. You could practise by listening to a set of instructions and then listing the main safety rules that were mentioned. Check you understand terms like 'flammable', 'corrosive', 'irritant' and 'toxic'.
听力理解练习通常会使用实验场景。你可以练习听一组指令，然后列出提到的主要安全规则。检查你是否理解“易燃”、“腐蚀性”、“刺激性”和“有毒”等术语。
7. Interpreting Experimental Results Orally | 口头解释实验结果
You might be given a table of results or a graph to describe out loud. Use phrases like 'as the independent variable increases, the dependent variable...' or 'the rate of reaction decreased when the temperature was lowered'.
你可能会被要求口头描述一个结果表格或图表。使用“随着自变量的增加，因变量……”或“当温度降低时，反应速率减慢”等表达。
When interpreting, point out trends, anomalies and conclusions. Say: 'The data shows that the mass of the product increased steadily over time. However, one reading at 50 seconds seems much lower than expected; this could be due to an instrumental error.'
在进行解释时，指出趋势、异常值和结论。可以这样说：“数据显示产物的质量随时间稳步增加。但在 50 秒时的一个读数似乎远低于预期，这可能是由于仪器误差造成的。”
For listening, you may be asked to identify which substance was in excess or to calculate a mean from spoken numbers. Practise listening for precise values and units, such as cm³, g, or °C. Write down what you hear and then speak your reasoning clearly.
在听力中，你可能会被要求判断哪种物质过量，或根据听到的数字计算平均值。练习听清精确的数值和单位，如 cm³、g 或 °C。把你听到的记下来，然后清晰地说出你的推理过程。
8. Answering 'Why' Questions in Chemistry | 回答化学中的“为什么”问题
'Why' questions test your ability to explain causes. You must go beyond stating what happened and explain the scientific reason. Use sentence starters like 'This happens because...', 'The reason for this is...' or 'This can be explained by...'.
“为什么”类问题测试你的解释能力。你不能只说明发生了什么，还要解释科学原因。使用“发生这种情况是因为……”、“原因是……”或“这可以用……来解释”等句首。
For example, if asked 'Why does a precipitate form when two solutions are mixed?', answer: 'A precipitate forms because the ions in the two solutions combine to create an insoluble compound that falls out of solution.' Mention specific ions if known, like Pb²⁺ and I⁻ forming yellow lead iodide.
例如，如果被问到“为什么两种溶液混合时会生成沉淀？”，可以回答：“生成沉淀是因为两种溶液中的离子结合形成了一种不溶于水的化合物，从溶液中析出。”如果知道具体离子可以提及，如 Pb²⁺ 和 I⁻ 生成黄色的碘化铅。
During listening exercises, pay attention to cause-and-effect linking words such as 'because', 'therefore', 'as a result' and 'due to'. These often signal the part of the response you need to write down or summarise.
在听力练习中，留意表示因果关系的连接词，如“because”、“therefore”、“as a result”和“due to”。它们通常标志着你需要记录或总结的回答部分。
9. Practising Pronunciation of Chemical Terms | 练习化学术语的发音
Mispronouncing key terms can make your answer harder to understand. Practise the sounds of words like 'anhydrous' (an-HY-drus), 'stoichiometry' (stoy-kee-OM-uh-tree), 'electrolysis' (ee-lek-TROL-uh-sis) and 'catalyst' (KAT-uh-list).
读错关键术语会让你的回答更难被理解。练习如“anhydrous”(an-HY-drus)、“stoichiometry”(stoy-kee-OM-uh-tree)、“electrolysis”(ee-lek-TROL-uh-sis) 和“catalyst”(KAT-uh-list) 等词的发音。
When describing ions aloud, say the element name followed by 'ion', for example 'sodium ion' for Na⁺, 'chloride ion' for Cl⁻, or 'copper(II) ion' for Cu²⁺. Be careful with numbers: 'iron(III) oxide' is Fe₂O₃, pronounced 'iron-three oxide'.
大声描述离子时，先说元素名称再说“离子”，例如 Na⁺ 为“钠离子”，Cl⁻ 为“氯离子”，或 Cu²⁺ 为“铜(II)离子”。注意数字的读法：Fe₂O₃ 是“氧化铁(III)”，读作“iron-three oxide”。
A good exercise is to record yourself explaining a concept, then listen back. Check whether your pronunciation is clear and whether you sound confident. You can also practise with a friend, asking them to correct any mispronunciations.
一个好的练习是把自己的概念解释录下来，然后回听。检查发音是否清晰，听起来是否自信。也可以和朋友一起练习，请他们纠正任何错误发音。
10. Sample Oral Question and Model Answer | 口语例题与示范回答
To see how a strong answer is structured, consider this typical question: 'Describe how you would prepare a pure sample of copper sulfate crystals from copper oxide and dilute sulfuric acid.' Here is a model response.
为了了解高分答案的结构，思考以下典型问题：“描述你将如何用氧化铜和稀硫酸制备纯净的硫酸铜晶体。”以下是一份示范回答。
Model Answer: 'First, I would warm some dilute sulfuric acid in a beaker. Then I would add copper oxide powder a little at a time, stirring continuously, until no more dissolves and the solution is saturated. Next, I would filter the mixture to remove any unreacted copper oxide, collecting the filtrate – which is copper sulfate solution – in an evaporating basin. I would heat the basin gently to evaporate some of the water, and then leave the remaining solution to crystallise slowly at room temperature. Blue copper sulfate crystals will form.'
示范回答： “首先，我会在烧杯中加热一些稀硫酸。然后少量多次地加入氧化铜粉末，不断搅拌，直到无法继续溶解，溶液达到饱和。接下来，我将混合物过滤以除去未反应的氧化铜，将滤液——即硫酸铜溶液——收集到蒸发皿中。我会缓慢加热蒸发皿，蒸发掉部分水，然后将剩余溶液在室温下缓慢结晶。蓝色硫酸铜晶体便会产生。”
Notice how the answer follows a logical sequence, uses correct scientific terms, and gives reasons for steps where needed. When you practise, try to speak in full sentences and avoid long pauses.
请注意该回答是如何遵循逻辑顺序、使用正确的科学术语并在需要时给出步骤理由的。练习时，努力说完整的句子，避免过长的停顿。
11. Listening Comprehension Practice: Steps of a Reaction | 听力理解练习：反应步骤
Let's simulate a listening task. Your teacher might say: 'In this experiment, we measure how the concentration of hydrochloric acid affects the rate of reaction with magnesium ribbon. We use 25 cm³ of acid in a conical flask, add a 3 cm strip of magnesium, and immediately attach a gas syringe. We record the volume of hydrogen gas collected every 10 seconds until no more gas is produced.'
我们来模拟一个听力任务。你的老师可能会说：“在本次实验中，我们测量盐酸浓度对镁带反应速率的影响。我们在锥形瓶中加入 25 cm³ 的酸，放入一条 3 厘米长的镁带，并立即连接气体注射器。我们每隔 10 秒记录所收集氢气的体积，直到不再产生气体为止。”
After listening, you might be asked to identify the independent variable (acid concentration), the dependent variable (gas volume), and two control variables (mass of magnesium, temperature). You could then explain why a gas syringe is used: 'It allows us to measure the volume of gas accurately as the reaction progresses.'
听完后，你可能会被要求找出自变量（酸浓度）、因变量（气体体积）以及两个控制变量（镁的质量、温度）。然后你要解释为什么使用气体注射器：“它可以让我们在反应进行中精确测量气体的体积。”
For extra practice, listen to a recorded description of an unfamiliar practical and try to draw a labelled diagram based on what you hear. This sharpens your listening accuracy and helps you connect spoken words with visual understanding.
为了额外练习，听一段关于不熟悉实验的录音描述，并尝试根据所听内容画出带有标注的示意图。这不仅能提高听力准确性，还能帮助你将听到的词语与视觉理解联系起来。
12. Final Tips for Exam Day | 考试当天最终建议
Arrive well rested and hydrated. Before the oral part, take a few deep breaths to calm any nerves. Remember that the examiner wants you to do well and is not trying to trick you. If you do not understand a question, politely ask for clarification: 'Could you please repeat the question?' or 'Could you explain what you mean by...?'
考试当天要休息好并补充水分。口语考试前，做几次深呼吸来平复紧张情绪。记住，考官希望你能表现出色，并不会故意为难你。如果没听懂问题，可以礼貌地请求澄清：“您能重复一下问题吗？”或“您能解释一下……的意思吗？”
When speaking, maintain a steady pace and look at the listener. Use your hands to gesture if it helps you explain. Even if you make a small mistake, keep going – you can often correct yourself smoothly: 'I mean, the solution turned green, not blue.'
说话时保持平稳的语速并看着听者。如有帮助，可以用手势辅助解释。即使犯了小错误，也要继续说下去——你通常可以顺畅地自我纠正：“我的意思是，溶液变成了绿色，而不是蓝色。”
Finally, treat the listening section as an active process: jot down key words while you listen, but do not write so much that you fall behind. Concentrate on the overall meaning first and then on details. With thorough preparation and a positive mindset, you will be ready to succeed.
最后，把听力部分当作一个主动过程：边听边记下关键词，但不要写太多以致跟不上。先把握整体意思，再关注细节。经过充分准备并保持积极心态，你将能够成功应对考试。
