3、不定式短語，在句中可以作主語、賓語、表語、定語（表用途）、狀語或補(bǔ)足語。高考對不定式的考查主要有不定式的時(shí)態(tài)、語態(tài)、作用、否定、省略、連詞不定式等。作主語不定式作主語表示具體的動(dòng)作，通常指一件已知的事或目的。不定式作主語時(shí)，謂語動(dòng)詞用單數(shù)。 eg:To say is a thing,to do is another.(說是一回事，做是另外一回事。)（2）不定式短語較長時(shí)，通常放在謂語之后，用it作形式主語。eg:It is important to learn English well.(學(xué)好英語是重要的。) It is necessary for us to do the job well.

4、(我們做好這項(xiàng)工作是必要的。)It is a great honor to be invited to give a speech here.(被邀請?jiān)谶@兒發(fā)表演講是一個(gè)極大的榮幸。)2.作賓語（1）常只用不定式作賓語的動(dòng)詞有：want,wish,hope,long,expect,desire,intend,decide,ask,promise,aim,offer,agree,plan,learn,choose,refuse,fail,manage,pretend等。 eg:He refused to help me.(他拒絕幫助我.)She has agreed to come tomorr

The only thing he could do was tell the truth.4.不定式作定語不定式作定語常放在所修飾的名詞或代詞后。eg:I have something important to tell you.(不定式與被修飾名詞構(gòu)成被動(dòng)關(guān)系。) His wish to an artist has never come t

( 不定式與被修飾名詞構(gòu)成主動(dòng)關(guān)系。)（注：若不定式為不及物動(dòng)詞，其后須加上相應(yīng)的介詞。)5.不定式作狀語不定式作狀語主要是表示目的、條件、原因和結(jié)果，可位于句首或句末，但句首時(shí)通常用逗號隔開。eg:We set off early that morning to catch the first bus.

9、（目的） To get a good result,she worked very hard.（目的） I feel it an honor to be invited to the party.(條件) She was very happy to get the first prize.(原因) He worked hard only to fail.(結(jié)果)(注：1.不定式常用在so as 或in order后,與它們一起作謂語，表示目的，但so as引起的不定式不可置于句首。eg:In order to avoid mistakes,check your homework. 2.不定式表

11、 were (only) too anxious to leave.(他們只是太急于離開了。) She is (only) too pleased to go home.(她非常高興可以回家了。)6.不定式作補(bǔ)語不定式作補(bǔ)語表示動(dòng)作的完成。賓語與作補(bǔ)語的不定式之間是主動(dòng)關(guān)系。（1）后接動(dòng)詞不定式作賓補(bǔ)的常見動(dòng)詞有：want,wish,expect,prefer,like,hate,ask,beg,request,require,beg,get,advise,persuade,invite,order,remind,permit,allow,send,callon,wouldlike/love,

We were greatly encouraged when we heard the speech.六非謂語動(dòng)詞的獨(dú)立結(jié)構(gòu)非謂語動(dòng)詞的獨(dú)立結(jié)構(gòu)為“名詞或代詞非謂語動(dòng)詞” 或“with名詞/代詞非謂語動(dòng)詞”。在語法上是一個(gè)獨(dú)立的短語，不是句子（即：非謂語動(dòng)詞的邏輯主語與主句主語不一致，須保留之后所構(gòu)成的結(jié)構(gòu)）?？煞旁诰涫谆蚓湮病?/p>

28、id,appreciate,consider（考慮）dislike,enjoy,escape,excuse,finish,imagine,keep,mind,miss(錯(cuò)過),practise,risk,resist,suggest等。（3）動(dòng)詞后二者都可跟，意義不同的有：forget to do sth 忘記要做某事forget doing sth 忘記做過某事regret to do sth 后悔要做某事regret doing sth 后悔做過某事go on to do sth 接著做另外一件事go on doing sth 接著做同一件事stop to do sth 停下來開始做某事s

29、top doing sth 停止做某事try to do sth 盡力做某事try doing sth 試著做某事mean to do sth 打算（意欲，企圖）做某事mean doing sth 意味著做某事cant help （to） do sth 不能幫忙做某事cant help doing sth 情不自禁地做某事 （4）動(dòng)詞后二者都可跟，意義相同的有：begin,start,like,love,prefer,hate等。但是區(qū)別在于：后接動(dòng)名詞時(shí)表示經(jīng)常性的動(dòng)作，后接不定式時(shí)表示的是具體的特定的動(dòng)作。eg:I like playing football,but I dont like

30、 play now.重點(diǎn)提示：在下列情況下begin和start后只接不定式：.主語是物不是人。eg:Spring came on and the snow began to melt.二者用于進(jìn)行時(shí) eg:Its begin to rain.二者后接表示心理活動(dòng)或狀態(tài)的動(dòng)詞。 eg:I began to realize how stupid I was.二者后接不定式的被動(dòng)式。 eg:The new type of computer began to be developed in the 1980s.（二）“感官動(dòng)詞賓語賓補(bǔ)（to do sth/doing sth）”的區(qū)別感官動(dòng)詞賓語賓補(bǔ)

31、（to do sth）表示事實(shí)或全過程感官動(dòng)詞賓語賓補(bǔ)（doing sth）表示片段或進(jìn)行eg:The missing boys were last seen playing near the river. Did you see a pencil-box lying on the ground just now.(三)個(gè)別“使讓動(dòng)詞賓語賓補(bǔ)”的特別詞的用法1）have賓語賓補(bǔ) have賓語do“讓做某事”，不定式作賓補(bǔ)可以指現(xiàn)在、將來或可能發(fā)生的動(dòng)作。eg:They had me repeat the message. I wont have you say such things. I w

32、ont have you blame it on me.have賓語doing “讓一直做某事”，現(xiàn)在分詞作賓補(bǔ)可以表示主語有意讓別人去做或無意引起某人可能去做或表示遭遇。eg:Tom tried to have her talking.But no use. I wont have you speaking to your parents like that. (注：have賓語doing 用于否定句，have有容忍之意。) Why should we have the boy standing in the corner the whole morning.have賓語done “讓被做”

33、過去分詞作賓補(bǔ)可表示主語有意識的行為或表示“遭遇”、“經(jīng)歷”（動(dòng)作違背主語的意愿）eg:We ought to have her examined by a doctor. The old woman had her handbag stolen.2）get賓語賓補(bǔ)get賓語to do(have賓語do) “讓做某事”有時(shí)則是“說服或勸說某人做某事”eg:I will get the publisher to illustrate(加上插圖) the book. get賓語doing“使（靜的物體）動(dòng)起來”，具有進(jìn)行含義。eg:I shall soon get the machine work
