Specific Suggestions for Student's Needs 针对学生需求的具体建议

Application & Evaluation (Essays): 应用与评估（论文）：

When answering 12-mark evaluation questions, explicitly include a paragraph addressing the limitations or variations of the impact (e.g., 'However, this impact will vary geographically...'). 回答 12 分评估题时，明确包含一个段落来讨论影响的局限性或变化（例如，“然而，这种影响在地理上会有所不同……”）。

Calculation Precision: 计算精确性：

For multi-component withdrawals (MPS, MPT, MPM), always write down the full denominator (e.g., 0.1 + 0.2 + 0.1 = 0.4) before calculating the final multiplier (1/0.4). 对于多组成部分的撤出项（MPS、MPT、MPM），在计算最终乘数（1/0.4）之前，务必写下完整的分母（例如，0.1 + 0.2 + 0.1 = 0.4）。

Terminology Control: 术语控制：

When defining 'Real Income', state clearly that it is 'adjusted for inflation' and avoid discussing the *causes* of inflation in that specific definition part. 在定义‘实际收入’时，明确说明它是‘经过通货膨胀调整的’，并避免在该特定定义部分讨论通货膨胀的*原因*。
