不定式和動(dòng)詞象一對(duì)姐妹一樣親密,本不該拆開來講,可是篇幅有限,只能讓他們分開了。不定式的構(gòu)成非常簡單,告訴我是什么?對(duì)!是to+動(dòng)詞原形。當(dāng)然啦,to有時(shí)也可以不帶。動(dòng)詞不定式?jīng)]有人稱和數(shù)的變化,可以擔(dān)當(dāng)除謂語外的任何句子成分。那什么時(shí)候可以不帶to呢? Listen to me carefully.
不定式省to有四種情況:
使役動(dòng)詞 let,have,make 等后接不定式。如:Let him go! 讓他走!
would rather,had better后。如:You had better stay at home.你最好呆在家里。
Why... / why not...后。如:Why not have a good rest on Sunday? 為什么星期天不好好休息一下呢?
感官動(dòng)詞 see, watch, look at, hear, listen to, smell,feel, find 等后作賓補(bǔ),省to。如:I saw him dance. 我看見他跳舞。
注意:這些情況在被動(dòng)句中可千萬不可省to 喲! 如:The boss made them work the whole night. 變成被動(dòng)句:They were made to work the whole night.
不定式的特殊用法:
It與不定式:動(dòng)詞不定式可以做主語,但如果動(dòng)詞不定式太長,顯得頭重腳輕的,那么我們就可用形式主語it代替,而把真正主語(即不定式)放于句尾。
如: It is not difficult for me to study English well.(對(duì)我來說學(xué)好英語是可能的。)
