动词不定式 一、不定式的基本形式 不定式 主动式 被动式 一般式 to do to be done ‎ 完成式 to have done to have been done 进行式 to be doing ‎ 完成进行式 to have been doing ‎1）不定式的一般式 ‎ 表示的动作通常与主要谓语所表示的动作（状态）同时（几乎同时）发生，或是在它之后发生。‎ ‎ 例如：We rejoiced to see her back.我们看到他回来了很高兴。‎ ‎ They invited us to go there this summer. 他们邀请我们今年夏天去那儿。‎ ‎2）不定式的进行式 ‎ 如果在主要谓语动词表示的动作发生时，不定式的动作也正在进行，这时不定式就要用进行式。‎ ‎ 例如：Her uncle seemed to be acting strangely towards her.‎ 她叔父对待她的所作所为看上去很怪。‎ ‎ They pretended to be working very hard.他们假装在努力工作。‎ ‎ We happened to be talking about it 我们恰好正谈到件事。‎ ‎ We did not expect you to be sleeping here.我们没想到你在这睡觉。‎ ‎3）不定式的完成式 ‎ 不定式所表示的动作在谓语所表示的动作之前发生，这个不定式用完成式，即to have done 例如：It is not like her to have missed two days of classed.‎ 误了两天的课，这不像她的行为。‎ ‎ I am sorry to have done that.我那样做很抱歉。‎ ‎ You are said to have got some tickets for the concert.‎ 据说你有几张这场音乐会的票。‎ ‎ She seems to have read the book before.她好像看过这本书。‎ ‎4）不定式的完成进行式。‎ ‎ 如果不定式的表示不是正在进行的动作，而是在谓语所表示时间前一直进行的动作，就要用完成进行式 。‎ 例如：They are said to have been collecting folk songs in Yunnan.(=It is said that they have been collecting...)据说他们一直在云南收集民歌。‎ ‎ They suspected us to having been puarreling. 他们还疑心我们刚刚吵过架呢。‎ ‎ We are happy to have been working with you. ‎ 我们很高兴这段时间和你们 在一起工作。‎ ‎5）不定式的被动式 ‎ （1）如果不定式的逻辑主语是不定式所表示的动作的承受者，不定式要用被动式 to be done 例如：These clothes are to be washed as soon as possible. 这些衣服要尽早洗。‎ ‎ It takes 80 years for Mediteranean Water to be changed with Atlantic water.‎ ‎ 地中海的水需要员80年才能同大西洋的水交换一次。‎ ‎ The new play to be put on tonight will be very interesting. ‎ 今晚要上演的新剧将十分有趣。 ‎ ‎ To fetch water before breakfast seemed to me a rule never to be broken. ‎ 早钣前去打水对我来说是永远不能打破的惯例。（98年上海高考）‎ ‎ （2）有些结构中不定式虽然表示被动意思，但用的却是主动形式，这是因为在句子中能找到不定式这个动作的发出者。‎ ‎ 例如：Give her some books to read. 给她些书看。‎ 有时候用不定式的主动式或被子动式表达的意义是不一样的。‎ 例如：I have some letters to write. 我有许多信要写。‎ ‎ I have some letters to be writen . 我有许多信要让人写。‎ ‎ Do you have anything to take to the library? ‎ 你有什么东西需要拿到图书馆去吗？（是由你亲自拿去）‎ Do you have anything to be taken to the library? ‎ 你有什么东西需要拿到图书馆去吗？（是由别人带去）‎ ‎（3）在There be 句型中作定语修饰主语的不定式用主动式和被子动形式都有可以。（多用主动形式）‎ ‎ 例如：There are a lot of letters to write (to be written) 有许多信要写。‎ ‎ There is no chance to lose (to be lost ) 机会失去不能再有。‎ 另外有些词用主动形式表示被子动意义：‎ 例如：He is to blame for not driving carefully 他粗心驾驶应受到责备。‎ ‎6）不定式的否定式 不定式的否定式是在to符号前加 not，有时用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失望。‎ ‎ I warn them not to go out alone.我告诫他们不要独自出去。‎ ‎ You must promise never to smoke.你必答应再也不抽烟。‎ ‎ I advised people not to have hamburgers.我劝人们不要吃汉堡包。‎ ‎ 动词不定式可在句中作主语、宾语、表语、定语、状语、补足语、同位语等， 但不能作谓语，不定式可有自己的逻辑主语，即for sb to do sth, of sb to do sth 一、 作主语 To do that sort of thing is foolish.‎ To learn English well is very important.‎ ‎ 注：常用形式主语it 代替不定式置于主语位置，不定式移至句末。‎ ‎ It would be better for you to go there. ‎ 一、 作表语 To see is to believe.‎ To live in hearts we leave behind is not to die .‎ ‎ 注：1、主语是不定式时，表语必须用不定式，而不用Ving形式。‎ ‎

2、当谓语是一些特定的动词时， 如：give , find , have , need, want 等，后面的名词（宾语或表语）可以用不定式修饰。‎ ‎ He gave us a week to think the problem over .‎ ‎ 3、当名词有特定的定语，如：first , last , next , only等序数词以及形容词最高级修饰时， 其后用不定式。‎ ‎ He is the only person to know the truth . ‎ ‎ 4. 一些要求不定式作宾语的动词转化为名词后，仍可带一个不定式作定语。如： agreement , attempt , decision ,promise wish , plan 等。‎ ‎ She has a great wish to travel around the world .‎ 四、 作状语 ‎
