【英语语法强调句型的例题解析】在英语学习过程中,强调句型是一个非常实用且常见的语法结构。它主要用于突出句子中的某个部分,比如时间、地点、人物或原因等,使表达更加清晰有力。掌握这一语法点不仅有助于提高语言表达能力,还能在写作和口语中增强逻辑性和表现力。
一、强调句型的基本结构
英语中常用的强调句型是:
It is/was + 被强调部分 + that/who + 其他成分
- It is/was + 时间/地点/人/原因 + that/who + 其他内容
- that 用于指代事物或抽象概念,who 用于指代人。
例如:
- It was in the library that I met her.(我是在图书馆遇见她的。)
- It is my teacher who helped me a lot.(帮助我的是我的老师。)
二、常见错误与注意事项
1. 混淆“that”和“who”的使用
当被强调的是人时,应该用 who;如果是其他内容,则用 that。
❌ It is the student that helped me.(如果学生是人,应使用 who)
✅ It is the student who helped me.
2. 误用“is”和“was”
根据句子的时态选择正确的助动词:
- 现在时:It is...
- 过去时:It was...
3. 不要遗漏“it”
强调句型必须以 It 开头,否则结构不完整。
三、典型例题解析
