中考英語語法講解資料及練不定式

1、xx英語語法講解資料及練習(xí)第6講：不定式不定式和動(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?Listentomecarefully.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：Lethimgo讓他走！wouldrather，hadbetter后。如：Youhadbetterstayathome你最好呆在家里。Why./whynot.后。如：Whynothaveag

2、oodrestonSunday為什么星期天不好好休息一下呢?感官動(dòng)詞see,watch,lookat,hear,listento,smell,feel,find等后作賓補(bǔ)，省to。如：Isawhimdance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：Thebossmadethemworkthewholenight.變成被動(dòng)句：Theyweremadetoworkthewholenight.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：Itisnotdiffic

3、ultformetostudyEnglishwell.（對(duì)我來說學(xué)好英語是可能的。）不定式還可以充當(dāng)句子的賓語，但有些動(dòng)詞，如find，think，believe等，在語法上不能接受不定式作賓語，只有用it作形式賓語，從而把動(dòng)詞不定式置于句尾。這樣的不定式可繼續(xù)充當(dāng)其賓語的作用。如：Ifounditdifficulttofallasleep.我發(fā)現(xiàn)很難入睡。還有一點(diǎn)：動(dòng)詞不定式，還可用在how，when，where，what，which等疑問代詞或副詞之后，與其共同作賓語。如：Idon'tknowhowtouseacomputer.我不知道怎樣使用電腦。Remember?too.to.

4、和enough.to：too.to表達(dá)"太.一致于不能."。enough.to表達(dá)"足以."。這兩個(gè)詞組的用法用兩個(gè)例子就可以說清楚了。Theboxistooheavyformetolift.這個(gè)箱子太沉了，我提不動(dòng)。HeisoldenoughtogotoschooI他到上學(xué)的年齡了。也就是說，他的年齡足夠上學(xué)了。記住這兩個(gè)句子就可以舉一反三，應(yīng)用自如。你記住了嗎？好吧，再試一把趁熱打鐵！練習(xí)：1.
