语法专题:非谓语动词和主谓一致
一、动词不定式
动词不定式可作主语、宾语、定语、状语和宾语补足语,我们主要掌握不定式作宾语、宾语补足语及目的状语的用法。
功能
例句
说明
主语
To swim here is dangerous.在这游泳很危险。
动词不定式作主语时常转化成it作形式主语。
表语

多数情况下,动词不定式作表语,可转换成作主语。
宾语
I want to be an actor.我想成为一名演员。
只能作某些动词的宾语,一般不作介词的宾语。
宾语补足语
She asked me to speak English.她要求我说英语。
在make\let\see\hear\watch等使役动词后,不定式省略to
定语
Do you have anything to say?你有话要说吗?
不定式作定语,要放在所修饰词的后面
状语
I come here to see you.我来这里是为了见你。
不定式作状语,其逻辑主语要和句子的主语一致。
此外,不定式可以与疑问词连用,用作主语、宾语、表语等。例句:
When to start hasn't been discussed.什么时候开始还没有被讨论。(作主语)
助记 只能跟不定式作宾语的动词

准备设法来帮忙(prepare, try, manage, help), 提供请求负担起(offer, beg, demand, afford),

2.语法一致原则的其他用法。
1)用and或both...and...连接的名词作主语时,谓语动词用复数形式。

6)由 cup,bottle,pair等计量单位名词修饰的名词充当主语时,谓语动词用单数还是复数形式由计量单位名词的单复数形式决定。
