非谓语是英语学习的重点也是难点,很多同学对这个语法知识一直是处于比较懵的状态。其实只要掌握非谓语所充当成分的用法就可以运用自如了。非谓语,顾名思义就是不做谓语的动词的变化形式,即to do ,doing,done。除了谓语,句子成分中还有主语、宾语、表语、宾语补足语、定语和状语。
下面看看不定式(to do)充当这6种成分的用法:
一、不定式作主语
1.To see is to believe.(这种情况不常用)
2. It is important to learn English well.
It 是形式主语,真正的主语是 to learn English well.这种用法是常用的而且是考点!考点!考点!
二、不定式作表语:常说明主语的内容、性质和特征或表动作将要发生。
1. My job is to keep the children safe.
2.My task is to type the article.
三、不定式做宾语
He prefers to eat white bread and rice.He wants to play football.
3.动词feel, find, make, think等后面,可以用it作形式宾语代替真正的宾语——动词不定式,句子结构是...feel / find / make / ... it+adj. / n.+to do...。
如:
I find it difficult to remember everything.
