【英语强调句的用法】在英语中，强调句是一种用来突出句子中某个特定部分的表达方式。它可以帮助说话者或写作者更清楚地传达重点信息，使句子更具表现力和逻辑性。常见的英语强调句结构有“it is/was...that/who...”结构，用于强调主语、宾语、时间、地点或原因等成分。
一、英语强调句的基本结构
| 结构 | 用法说明 |
| It is/was + 被强调部分 + that/who + 其余部分 | 强调主语、宾语、时间、地点、原因等 |
- It is 用于现在时或一般将来时
- It was 用于过去时
- that 用于强调人或物
- who 仅用于强调人
二、强调句的常见类型
| 强调内容 | 示例句子（原句） | 强调句形式 |
| 主语 | He gave me a gift. | It was he who gave me a gift. |
| 宾语 | I saw her yesterday. | It was her that I saw yesterday. |
| 时间 | She arrived at 8 o'clock. | It was at 8 o'clock that she arrived. |
| 地点 | They met in the park. | It was in the park that they met. |
| 原因 | He failed because he was lazy. | It was because he was lazy that he failed. |
三、强调句与普通句的区别
| 句子类型 | 是否使用强调结构 | 是否改变原意 |
| 普通句 | 否 | 无变化 |
| 强调句 | 是 | 突出某部分 |
例如：
- 普通句：She went to the store.
- 强调句：It was to the store that she went.
四、注意事项
1. 强调句不能强调谓语动词：
- 错误：It was he that went to the store.（正确）
- 错误：It was went that he to the store.（错误）
2. 强调人时可用“who”，强调物时用“that”：
- It was the teacher who helped me.
- It was the book that I lost.
3. 强调时间或地点时，通常用“that”：
- It was last year that we met.
- It was there that I found the key.
五、总结
英语强调句是表达重点的一种有效手段，通过“it is/was...that/who...”结构，可以清晰地突出句子中的关键信息。掌握这一结构不仅有助于提高语言表达能力，还能增强写作和口语的逻辑性和表现力。在实际运用中，需注意不同成分的强调方式以及“that”和“who”的使用规则，避免语法错误。
