知识点 2

Evaluate whether a detail is relevant and supportive vs off-topic or distracting.

核心知识

A detail belongs only if it helps the reader understand, prove, or sharpen the main point. If it only adds color or wanders to a side topic, cut it.

深入理解

Rule: A detail belongs only if it helps the reader understand, prove, or sharpen the main point. If it only adds color or wanders to a side topic, cut it.

  • Relevance is about function, not about whether a fact is interesting.
  • A sentence can be vivid, true, and still distract from the paragraph's purpose.
  • If you cannot explain how the detail supports the main point, it probably does not belong.

分步讲解

  1. Identify the paragraph's main point.
  2. Ask what the proposed detail adds to that point.
  3. Keep the detail only if it provides support, explanation, or needed context.
  4. Reject the detail if it shifts the reader's attention elsewhere.

常见误解

  • Keeping a detail because it is memorable or descriptive.
  • Assuming any sentence about the same setting is automatically relevant.
  • Choosing the answer with more information even when focus becomes weaker.
