因果推理链 (Cause & Effect Chains)

核心逻辑：深度扩展（Elaboration）。不要只给观点，要解释“为什么”。

1. 简单因果

• Because of / Due to / Owing to + Noun
  • Example: Due to lack of funding, the project failed.
• Since / As + Sentence
  • Example: Since housing is expensive, many young people rent.

2. 动词化的因果 (更高级)

• contribute to (促成/导致 - 中性/积极)

• lead to / result in (导致)

• trigger / spark (引发 - 突然)

• engender (产生 - 某种情感/局势)

• Example: Poor diet contributes to obesity. (= Poor diet causes obesity)

3. 链式推导 (PEEL 核心)

A -> B -> C。这能让你的论证非常有深度。

• Template: [Action A]. This, in turn, leads to [Result B], which ultimately results in [Result C].

• Example: The government invests in education. (A) → This leads to a more skilled workforce. (B) → , which ultimately results in higher economic productivity for the nation. (C)
