📚 CAIE Year 10 Biology: Exam Technique and Marking Criteria | CAIE 10年级生物：答题技巧与评分标准

Achieving a high grade in CAIE Year 10 Biology (IGCSE 0610) requires more than memorising facts. You must understand exactly what examiners are looking for and how to structure your answers to gain all available marks. This guide breaks down the essential exam techniques and marking criteria that will transform your biological knowledge into top marks.

在CAIE 10年级生物（IGCSE 0610）中获得高分，不仅仅是记忆知识点。你必须准确理解考官的评分要求，并掌握如何组织答案以获得全部分数。本指南将解析关键的答题技巧和评分标准，帮助你把生物学知识转化为高分。

1. Understanding Command Words | 理解指令词

Command words are the first key to success. They tell you exactly what the examiner expects from your answer. Common command words in CAIE Biology include: State, Describe, Explain, Suggest, Calculate, Compare, and Evaluate.

指令词是成功的第一把钥匙。它们明确告诉了你考官对你的答案有何期望。CAIE生物考试中常见的指令词包括：State（陈述）、Describe（描述）、Explain（解释）、Suggest（建议）、Calculate（计算）、Compare（比较）和Evaluate（评估）。

‘State’ demands a brief, factual answer, often just a term or short phrase. For instance, ‘State the name of the pigment that absorbs light in photosynthesis.’ Answer: Chlorophyll. No explanation is required.

“State”要求一个简短、事实性的答案，通常只是一个术语或短语。例如，“陈述光合作用中吸收光的色素名称。”答案：叶绿素。无需解释。

‘Describe’ asks you to give an account of what you see or what happens, without giving reasons. Focus on patterns, trends, and data comparisons.

“Describe”要求你叙述所看到的或所发生的事情，而不用说明原因。关注模式、趋势和数据比较。

‘Explain’ requires you to give biological reasons, often using the words ‘because’ or ‘so that’. You must link causes to effects using scientific principles.

“Explain”要求你给出生物学原因，通常使用“因为”或“以便”之类的词。你必须运用科学原理将原因和结果联系起来。

‘Suggest’ is an application question where you might not have learned the exact answer, but you can use your biological knowledge to propose a reasonable explanation or hypothesis.

“Suggest”是一道应用题，你可能没有学过确切答案，但你可以运用生物学知识提出合理的解释或假设。

‘Calculate’ involves mathematical working. Always show your formula, substitution, and final units. CAIE expects a clear method.

“Calculate”涉及数学运算。始终要写出公式、代入量及最终单位。CAIE期望有清晰的过程。

‘Compare’ requires you to identify similarities and differences. Use linking words like ‘whereas’ or ‘in contrast’. For similarities, use ‘both’ or ‘similarly’.

“Compare”要求你指出相同点和不同点。使用“而”、“相比之下”等连接词；对于相同点，使用“两者都”或“类似地”。

‘Evaluate’ asks you to weigh up evidence, discussing both strengths and limitations, often concluding with a justified opinion.

“Evaluate”要求你权衡证据，既讨论优点也讨论局限性，通常最终给出有依据的结论。

2. The Art of ‘Describe’ Questions | “描述”题的艺术

In ‘describe’ questions, you must avoid explaining. Instead, tell the reader what is happening. If a graph is provided, describe the overall shape, any peaks or troughs, and quote data points. Say ‘increases from… to…’ or ‘reaches a maximum at…’.

在“描述”题中，你必须避免进行解释。相反，你要告诉读者正在发生什么。如果给出了图表，要描述整体形状、任何波峰或波谷，并引用数据点。要说“从…增加到…”或“在…处达到最大值”。

For example, when describing the effect of pH on enzyme activity, state: ‘The rate of reaction increases as pH rises from 4 to 7,
