轻松学会 It is/was … that/who … 强调结构，让你的英语表达更具说服力
在英语表达中，有时我们希望强调某个特定信息，这时就需要用到强调句结构。而最常见的强调方式就是：
It is/was + 被强调部分 + that/who + 句子其他部分
一、什么是强调句型？
强调句（Cleft Sentence）是一种通过特殊句型形式，突出句中某个成分的结构。
基本结构：
It is/was + 被强调成分 + that/who + 剩余部分
例句：
- 原句：Tom helped me with the homework.
- 强调主语：It was Tom who helped me with the homework.
- 强调宾语：It was me that Tom helped with the homework.
- 强调时间状语：It was last night that Tom helped me.
这就是“强调谁”、“强调什么”、“强调何时”的用法转换。
二、结构要点
- that 用于强调“时间”“地点”“宾语”等
- who 用于强调“人做动作”（即主语为人）
- 被强调部分通常是主语、宾语或状语，不能强调谓语！
三、时态一致性
强调句的 is/was 与原句时态保持一致：
- 一般现在时 → It is
- 一般过去时 → It was
例句：
I saw her in the library. → It was in the library that I saw her.
四、常见误区对比
| 错误表达 | 正确表达 | 说明 |
|---|---|---|
| It is goes to school that he every day. | It is to school that he goes every day. | 被强调部分位置错误 |
| It was helped me that Tom. | It was Tom who helped me. | 主谓颠倒 |
| It is playing football that he enjoys. | It is football that he enjoys playing. | 句式不当 |
五、应用场景提升表达层次
强调句广泛用于写作首句或段落核心句，增强信息突显度，提升语言的逻辑感。
对比范例：
普通句式：
Mary studied very hard for the exam.
强调句式：
It was Mary who studied very hard for the exam.
It was for the exam that Mary studied very hard.
这种表达方式更具力量感与结构清晰度。
六、范文片段示例（话题：努力与成功）
It is not luck but effort that leads to success.
It was during high school that I realized the importance of self-discipline.
It is those who never give up who truly achieve greatness.
强调句常用于议论文开头与段落总结，突显作者立场。
