非谓语动词(不定式、动名词)【考点概述】非谓语动词的本意是不能做谓语的词性,但是它具有谓语动词的性质。
非谓语动词是英语中特有的,在汉语中没有此概念。
所以在掌握此语法是比较困难的,在平时的备考之中应注意多多练习。
【考点释义】考点一:不定式(1)构成:to+动词原形(do)如:I like to swim.注意:不定式有省“to”的不定式和不省“to”的不定式两类,但多数以不省“to”的不定式为主。
如:I heard him (to)sing. 我听到他在唱歌。
(2)句法功能:1. 作主语在英语中为了避免头重脚轻,当不定式作主语时有时主语太长时我们用形式主语“it”来作“形式主语”,将真正主语移植动词不定时之后。
形式主语也就是我们所说的“不定式的复合结构”。
其构成为“It +be +(for/of sb) to do sth. 如:① It is very important ( us) to study English.= To study English is very important for us. 学英语对我们来说是很重要的② It is very kind ( you) to help me.= To help me is very kind of you. 你帮助我太好了。
当介词“of词“of”或“for”。
如果能够成主谓逻辑关系时我们使用介词“of”,反之则用介词“for”。
例如上述两个例子。
①It is very important (for us) to study English. Us is very important.(不成立)由于不能构成主谓关系,所以用介词“for”。
②It is very kind (of you) to help me. You are very kind. (成立)由于构成主谓关系,所以用介词“of”。
2. 作宾语当动词不定式作宾语是表示的是一种打算、希望、命令等。
