OCR使用特定的指令词：“陈述”、“描述”、“解释”、“评估”、“计算”、“比较”。确切知道每个指令词的要求。
'Explain' requires a scientific reason, often linking cause and effect with 'because'. 'Evaluate' means weigh pros and cons before making a justified conclusion.
“解释”需要科学原因，经常使用“因为”把因果联系起来。“评估”意味着在做出有依据的结论之前权衡利弊。
Use the mark allocation as a guide: a 1-mark question requires a short, precise answer; a 6-mark question expects a detailed, logically structured paragraph with correct scientific terminology.
