深入剖析英语强调句的构成、意义与应用策略，助力提升写作表达力
一、强调句型的基本结构与功能
强调句型用于将原句中的某一部分加以突出，结构如下：
It is/was + 被强调部分 + that + 句子其他部分
例如：
- 原句：She visited the museum last Saturday.
- 强调宾语：It was the museum that she visited last Saturday.
- 强调时间：It was last Saturday that she visited the museum.
该结构广泛应用于口语与写作，特别适合用于强调时间、地点、人物等信息，使表达更具针对性。
二、强调句型的适用范围
强调句适用于以下句子成分：
- 主语：It was John that broke the window.
- 宾语：It is the truth that he wants to know.
- 状语（时间/地点）：It was in 2019 that the company was founded.
❗ 注意：不能用于强调谓语动词本身。
三、与原句的对比分析
以下是强调句与普通句的转换示例：
| 普通句 | 强调句 |
|---|---|
| Lily prepared the presentation carefully. | It was Lily that prepared the presentation carefully. |
| They held the conference in Beijing. | It was in Beijing that they held the conference. |
这些转换形式在议论文和说明文中尤为常见，能有效增强句子逻辑和说服力。
四、写作范文片段展示
It was the final exam that determined their future placement.
It is not luck but consistent effort that leads to success.
It was with great care that the experiment was conducted.
在以上片段中，强调结构不仅使重点信息更突出，也让表达更加正式、规范。
五、常见错误警示与纠正建议
- ❌ It is to travel that she wants.
✅ 应改为：It is travel that she wants.
强调成分需为句子基本结构成员，不能误用动词短语或从句。
- ❌ It is happy that he feels.
✅ 应改为：It is he that feels happy.
不能强调表语或感受，重点需放在主语、宾语或时间地点等成分上。
六、教学建议与训练任务
建议读者将以下句子转化为强调句：
- He won the prize in 2022.
- Mary completed the task alone.
- They met the professor at the seminar.
在训练中巩固结构识别、句式重构等技能，提升句型控制力。
总结：
强调句结构是中高级写作的重要组成部分，特别适用于需要突出信息、增强论点的场合。掌握该结构有助于你在考试作文与实际应用中表达更有力、更具层次。
