核心知识
A strong introduction gives the reader enough context to enter the paragraph and points toward the exact idea the paragraph will develop.
深入理解
Rule: A strong introduction gives the reader enough context to enter the paragraph and points toward the exact idea the paragraph will develop.
- The opening sentence should not try to cover every angle.
- It should name the topic in a way that prepares the reader for the specific point that follows.
- Trap: an introduction that is either too broad to be useful or too far from the paragraph's focus.
分步讲解
- Read the rest of the paragraph to identify its exact focus.
- Reject openings that wander into history, trivia, or a different subtopic.
- Choose an opener that gives context and leads naturally into the next sentences.
- Make sure the tone and level of detail match the paragraph.
常见误解
- Choosing the broadest sentence because it sounds important.
- Opening with a detail that is too narrow before the reader has context.
- Introducing a topic the paragraph never actually develops.
