主语从句是英语语法中的重要部分,它可以用来描述主语的身份、状态或行为。在英语中,主语从句的构造方式有很多种,但是有一些常用的结构需要我们掌握。
1. Wh- 从句
Wh- 从句是主语从句中最常用的一种结构。它以 wh- 开头,例如:what, who, where, when, why, how 等。这种结构中,从句本身就是一个完整的句子,它可以独立地作为主语,例如:
- What you said is not true.
- Who is going to the movie tonight?
- Where we go for dinner tonight is still undecided.
2. That 从句
That 从句是主语从句的另一种常用结构,它以 that 开头。和 wh- 从句不同,that 从句通常不需要逗号来分隔,例如:
- That he is always late annoys me.
- That we have a test tomorrow is not a good thing.
- That she is a good singer is well-known to everyone.
3. To 不定式从句
To 不定式从句是指以 to 开头的从句。这种结构通常用来表达一个目的或者一个计划,例如:
- To learn a foreign language is important for everyone.
- To finish this project on time is our goal.
- To make a cake, you need to have all the ingredients ready.
以上就是英语常用主语从句结构的介绍。掌握这些结构,可以让我们更加流畅地表达自己的想法和意见,同时也可以帮助我们更好地理解英语语法。
