一、不定式的作用

??1、作主語

??不定式作主語時(shí),謂語用單數(shù)。往往用it 作形式主語,把不定式放在謂語后面。如:

??It took us two hours to finish the job.

??It is impossible for us to get there on time.

??注意:

??(1)其他系動(dòng)詞如look, appear等也可用于此句型。

??(2)當(dāng)不定式作主語的句子中又有一個(gè)不定式作表語時(shí),不能用It is …to…的句型。試比較:It is to negate my own idea to believe him.(錯(cuò))

??To believe him is to negate my own idea .(對(duì))

??3)It is+ adj.+ of / for sb. to do sth. 結(jié)構(gòu)中,當(dāng)不定式的邏輯主語和前面的形容詞可以構(gòu)成系表結(jié)構(gòu)時(shí),用of, 否則用 for.

??2、作賓語

??(1)動(dòng)詞+不定式。如:

??He managed to escape from the fire.

??I find it hard to get along with him.(it 作形式賓語)

??注:下列動(dòng)詞通常用不定式作賓語:want, try, hope, wish, need, forget, know, promise, refuse, help, decide, begin, start, learn, agree, choose, get等

??(2)動(dòng)詞+疑問詞+to , “特殊疑問句+不定式”相當(dāng)于名詞,作賓語。如:

??I don’t know what to do next/ how to do it next.

??注意:不定式短語作賓語時(shí),如果還帶有賓語補(bǔ)足語,往往把不定式短語放在賓語補(bǔ)足語之后,用it 作形式賓語。如:

??I find it necessary to learn a foreign language.

??3、作賓語補(bǔ)足語

??(1)動(dòng)詞+賓語+不定式(to do)。如:

??He warned me to be careful.

??What makes you think so?(不帶to的不定式)

??注:可以用動(dòng)詞不定式做賓補(bǔ)的動(dòng)詞有:ask, tell, order ,want ,get, would like, like, advise, invite, allow, help, wish, warn, expect, prefer, encourage

??(2)表見解、看法的動(dòng)詞結(jié)構(gòu)可為:動(dòng)詞+賓語+ to be 的不定式結(jié)構(gòu)。如:

??We consider Tom to be one of the best students in our class.

??The book is believed to be useful.(被動(dòng)語態(tài))

??(3) There +不定式。如:

??We didn’t expect there to be so many people there.我們沒料到會(huì)有那么多人在那里。

??注意:(1)有些動(dòng)詞需用 as 短語作補(bǔ)語,像regard, think, believe, take, consider。如:

??We regard Tom as our best teacher.

??Mary took him as her father.

??(2)在動(dòng)詞feel (一感),hear, listen to(二聽),have, let, make(三讓),notice, see, watch, observe, look at(五看)(即:吾看三室兩廳一感覺)等后面的補(bǔ)足語中,不定式不帶to,但變?yōu)楸粍?dòng)語態(tài)后,必須帶to。如:

??They saw the boy fall off the tree.

??The boy was seen to fall off the tree.
