高考語法復習 動詞不定式學案

1、.動詞不定式一、不定式的根本形式不定式 主動式 被動式一般式 to do to be done 完成式 to have done to have been done進展式 to be doing 完成進展式 to have been doing1不定式的一般式 表示的動作通常與主要謂語所表示的動作狀態(tài)同時幾乎同時發(fā)生，或是在它之后發(fā)生。 例如：We rejoiced to see her back.我們看到他回來了很快樂。 They invited us to go there this summer. 他們邀請我們今年夏天去那兒。2不定式的進展式 假如在主要謂語動詞表示的動作發(fā)生時，不定式的

2、動作也正在進展，這時不定式就要用進展式。 例如：Her uncle seemed to be acting strangely towards her.她叔父對待她的所作所為看上去很怪。 They pretended to be working very hard.他們假裝在努力工作。 We happened to be talking about it 我們恰好正談到件事。 We did not expect you to be sleeping here.我們沒想到你在這睡覺。3不定式的完成式 不定式所表示的動作在謂語所表示的動作之前發(fā)生，這個不定式用完成式，即to have done例如

3、：It is not like her to have missed two days of classed.誤了兩天的課，這不像她的行為。 I am sorry to have done that.我那樣做很抱歉。 You are said to have got some tickets for the concert.據(jù)說你有幾張這場音樂會的票。 She seems to have read the book before.她好似看過這本書。4不定式的完成進展式。 假如不定式的表示不是正在進展的動作，而是在謂語所表示時間前一直進展的動作，就要用完成進展式 。例如：They are sai

4、d to have been collecting folk songs in Yunnan.=It is said that they have been collecting.據(jù)說他們一直在云南搜集民歌。 They suspected us to having been puarreling. 他們還疑心我們剛剛吵過架呢。 We are happy to have been working with you. 我們很快樂這段時間和你們 在一起工作。5不定式的被動式 1假如不定式的邏輯主語是不定式所表示的動作的承受者，不定式要用被動式 to be done例如：These clothes a

5、re to be washed as soon as possible. 這些衣服要盡早洗。 It takes 80 years for Mediteranean Water to be changed with Atlantic water. 地中海的水需要員80年才能同大西洋的水交換一次。 The new play to be put on tonight will be very interesting. 今晚要上演的新劇將非常有趣。 To fetch water before breakfast seemed to me a rule never to be broken. 早鈑前去打

6、水對我來說是永遠不能打破的慣例。98年上海高考 2有些構(gòu)造中不定式雖然表示被動意思，但用的卻是主動形式，這是因為在句子中能找到不定式這個動作的發(fā)出者。 例如：Give her some books to read. 給她些書看。有時候用不定式的主動式或被子動式表達的意義是不一樣的。例如：I have some letters to write. 我有許多信要寫。 I have some letters to be writen . 我有許多信要讓人寫。 Do you have anything to take to the library? 你有什么東西需要拿到圖書館去嗎？是由你親自拿去Do

7、you have anything to be taken to the library? 你有什么東西需要拿到圖書館去嗎？是由別人帶去3在There be 句型中作定語修飾主語的不定式用主動式和被子動形式都有可以。多用主動形式 例如：There are a lot of letters to write to be written 有許多信要寫。 There is no chance to lose to be lost 時機失去不能再有。另外有些詞用主動形式表示被子動意義：例如：He is to blame for not driving carefully 他粗心駕駛應受到責備。6不定式

8、的否認式不定式的否認式是在to符號前加 not，有時用never ,即not to do sth , never to do sth.例如：He is disappointed not to go swimming this afternoon.今天下午不能去游泳他很絕望。 I warn them not to go out alone.我告誡他們不要單獨出去。 You must promise never to smoke.你必容許再也不抽煙。 I advised people not to have hamburgers.我勸人們不要吃漢堡包。 動詞不定式可在句中作主語、賓語、表語、定語、
