【强调句句型】在英语语法中，“强调句句型”是一种用于突出句子某一成分的结构，常用于表达说话者的重点或强调某个特定信息。常见的强调句型有“it is/was...that/who...”结构，能够将句子中的主语、宾语、状语等部分进行强调，使语言表达更加清晰和有力。
一、强调句句型总结
| 结构 | 用法说明 | 示例 |
| It is/was + 被强调部分 + that/who + 其余部分 | 用于强调主语、宾语、状语等 | It was John who called me yesterday. |
| It is/was + 时间/地点 + that + 其余部分 | 强调时间或地点 | It was in the library that I met her. |
| It is/was + not until...that... | 表示“直到……才……” | It was not until 10 o'clock that he arrived. |
二、强调句句型的使用要点
1. 强调主语：
- 原句：John wrote the letter.
- 强调句：It was John who wrote the letter.
2. 强调宾语：
- 原句：I saw Mary in the park.
- 强调句：It was Mary that I saw in the park.
3. 强调时间或地点：
- 原句：We met at the station.
- 强调句：It was at the station that we met.
4. 强调原因或方式：

- 强调句：It was because she studied hard that she passed the exam.
5. 强调否定意义：

三、强调句句型与普通句型的区别
| 句型 | 是否强调 | 举例 |
| Ordinary sentence | 否 | She gave the book to him. |
| Emphatic sentence | 是 | It was him that she gave the book to. |
四、常见错误与注意事项
- 不要混淆“that”和“which”：强调句中只能用“that”，不能用“which”。
- 注意时态一致：强调句的“is/was”要与原句的时态保持一致。
- 避免重复强调：不要在一个句子中多次使用强调结构，以免显得累赘。
通过掌握“强调句句型”，可以更有效地表达自己的意思，特别是在写作或口语中突出关键信息。熟练运用这一结构，不仅能让语言更具逻辑性，也能提升表达的准确性与专业性。
