10. Tips for Answering Long-Answer Questions | 长答题作答技巧
Long-answer questions, often worth 6-8 marks, test extended writing and application. A highly effective technique is to adopt the 'PEEL' structure: Point, Example, Explanation, and Link back to the question. This ensures that answers are logical, fully developed, and hit all marking points.
长答题通常分值 6-8 分，考查拓展写作和应用能力。一项高效技巧是采用 'PEEL' 结构：观点 (Point)、实例 (Example)、解释 (Explanation) 和回扣题目 (Link)。这确保答案逻辑清晰、充分展开并覆盖所有得分点。
Past papers reveal that students often lose marks by providing vague statements. For instance, instead of saying 'use a strong material,' write 'use mild steel because its high tensile strength and malleability make it ideal for load-bearing brackets.' Quantitative data, where applicable, impresses examiners.
历年真题显示，学生常因陈述含糊而失分。例如，与其说 '使用坚固的材料'，不如写 '使用低碳钢，因为它具有高拉伸强度和延展性，非常适合承重支架'。在适用时加入量化数据会给考官留下深刻印象。
Always read the command word carefully. 'Describe' requires a detailed picture, while 'Explain' needs a reason or cause. 'Calculate' demands a numerical answer with units. Underlining key terms in the question prevents misinterpretation.
始终仔细阅读指令词。'Describe (描述)' 要求详细描述画面，而 'Explain (解释)' 需要给出原因或缘由。'Calculate (计算)' 则要求带单位的数值答案。划出题目中的关键术语可防止误解。
