【正文】 ork with him. 注意:在feel,hear,notice,observe,see,watch,have,let,make等詞后的補足語中,不定式不帶to。但這些句子如果變成被動結構時,就必須帶to。如: I often hear him sing the song. He is often heard to sing the song. 注意:動詞不定式在介詞but后面時,如果介詞之前有行為動詞do的各種形式,那么,這些介詞后的不定式不帶to,否則要帶to。另外,在can’t choose but和can’t help but等后面的不定式也省略to。如: She could do nothing but cry. I have no choice but to go. 4)作定語。如: I have some books for you to read. ①作定語的不定式如果是不及物動詞,或者不定式所修飾的名詞或代詞是不定式動作的地點、工具等,不定式后面須有相應的介詞。如: He is looking for a room to live in. There is nothing to worry about. Please give me a knife to cut with. 但是,不定式所修飾的名詞如果是time,place或way,不定式后面的介詞習慣上省去。如: He had not money and no place to live. ②當作定語的不定式所修飾的名詞或代詞是不定式動作的承受者時,不定式既可以用主動語態(tài),也可用被動語態(tài),但其含義有所不同。試比較: Have you anything to send ? (你有什么東西要寄嗎?——不定式to send的動作執(zhí)行者是“你”) Have you anything to be seat. [你有什么要(我或別人)寄的東西嗎?——不定式to be sent的動作執(zhí)行者是“我”或“別人”] 5)作狀語,表示目的、原因、結果或條件。如: I came here to see you. (目的) We were very excited to hear the news. (原因) He hurried to the school to find nobody there. (結果) To look at him, you would like him. (條件) 目的狀語還可以用in order to或so as to來表示但so as to不能置于句首。如: In order to pass the exam, he worked very hard. We ran all the way so as not to be late. 不定式也可以在作表語用的形容詞后面作狀語。如: I am very glad to hear it. The question is difficult to answer. “too + 形容詞或副詞 + 不定式”作狀語。如: He is too old to do that. 另外,句子中有enough這個詞時,常用不定式作狀語。例如: The room is big enough to hold us. 6)作表語。如: My job is to help the patient. 7)作獨立成分。如: To tell the truth, I don’t agree with you. 8)不定式與疑問詞who,which,when,where,how,what等連用,在句中起名詞作用,可充當主語、表語、賓語等。如: He didn’t know what to say. (賓語) How to solve the problem is very important. (主語) 注意:在與why連用時,只用于why或why not開頭的簡短疑問句中,后面緊跟的動詞不定式不帶to。例如: Why not have a rest ? 9)不定式在句中用主動式還是被動式,多數(shù)情況下是容易判斷的,但有時的確比較復雜,請注意以下幾點: ①不定式修飾的名詞或代詞和不定式邏輯上構成主謂關系時,不定式往往用主動形式。如: Have you got a key to unlock the door ? (A key unlocks the door. ) ②不定式和它前面被修飾的名詞或代詞構成邏輯上的動賓關系,又和該句主語構成邏輯上的主謂關系時,不定式常用主動形式。 I have got a letter to write. (I write letter. ) He needs a room to live in. (He lives in a room. ) I know what to do. (I do what. ) 但這句如改為下列形式,不定式就得用被動形式:I know what is to be done. 這是因為what is to be done是賓語從句,從句中的主語what是動詞do的動作對象。 ③不定式作表語形容詞的狀語,和句中主語構成邏輯上的動賓關系時,不定式多用主動形式,這是因為人們往往認為形容詞后省去了for sb. 。如: He is hard to talk to. (to talk to him) The book is difficult to understand. (to understand the book) ④在there be結構中,當說話人考慮的是必須有人去完成某件事時,不定式用主動形式;如果說話人強調的事情本身必須完成,則用被動形式。 There is a lot of work to do. (Somebody has to do the work. ) There is a lot of work to be done. (The work has to be done. ) 請注意下面兩個句子的含義是不同的: There is nothing to do. (無事可做,感到十分乏味。) There is nothing to be done. (某東西壞了,無法使之恢復正常。) 2.不定式的時態(tài) 1)不定式的一般形式所表示的動作,通常與謂語的動作(狀態(tài))同時(或幾乎同時)發(fā)生,或是在它之后發(fā)生。例如: I saw him go out. 2)如果謂語表示的動作(情況)發(fā)生時,不定式表示的動作正在進行,這時不定式就要用進行式。例如: He pretended to be reading a book when she went in. 3)如果不定式的動作發(fā)生在謂語動詞之前,就要用完成式。例如: I’m sorry to have kept you waiting. 3.不定式的語態(tài) 當不定式邏輯上的主語是這個不定式所表示的動作的承受者時,不定式一般要用被動形式。如: He asked to be sent to work in the countryside. It is possible for our hopes to be realized. 4.不定式符號to的保留問題 有時為了避免重復,可以用to來代替前面的不定式,這種情況常出現(xiàn)下列動詞后:expect,prefer,care,mean,forget,want,wish,hope,try以及be glad/happy等后。 如果在省略的不定式結構中含有be,have,have been,這些詞要保留。如: —Are you on holidays ? —No, but I’d like to be. —I didn’t tell him the news. —Oh, you ought to have動詞不定式、動名詞用法要點講解詳細內容⒈不定式作主語 動詞不定式作主語時,句子的謂語動詞常用單數(shù),其位置有以下兩種: (1)把不定式置于句首。如: To get there by bike will take us half an hour. (2)用it作形式主語,把真正的主語不定式置于句后,常用于下列句式中。如: ①It+be+名詞+to do It39。s our duty to take good care of the old. ②It takes sb+some time+to do How long did it take you to finish the work? ③It+be+形容詞+for sb+to do It is difficult for us to finish writing the positionin a quarter of an hour. ④It+be+形容詞+of sb+to do It is stupid of you to write down everything the teachersays. ⑤It seems(appears)+形容詞+to do It seemed impossible to save money. 在句型③中,常用表示客觀情況的形容詞,如:difficult,easy,hard,important,impossible,necessary 等;在句型④中,常用careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise等 表示贊揚或批評的詞。在不定式前的sb,可看作其邏輯主語。這一句式有時相當于Sb is+形容詞+to do句式 ,如:It39。skind of you to help me with my English.=You are kind to helpme with my English. ⒉動名詞作主語 Learning without practice is no good. 動名詞作主語時,也常用It句式。如: ①It39。s +no good(no use,fun,a pleasure,a waste of time)+doing… It39。s no good reading in dim light. It39。s no use sitting here waiting. ②It39。s+形容詞+doing It39。s dangerous swimming in the sea in windy days. 這樣用的形容詞有expensive,nice,tiring等,但important,necessary則不適用于這種結構,應用不定式 代替,如:It39。simportant for you to keep fit. ③There is no+doing There is no saying what will happen next. 在這一結構中,動名詞后常帶賓語,相當于It39。s impossible to…結構。 ⒊動詞不定式和動名詞作主語的區(qū)別 ①不定式作主語經(jīng)常表示具體動作,常與特定的動作執(zhí)行者聯(lián)系在一起;而動名詞作主語經(jīng)常表示抽象動 作,經(jīng)常不與特定的動作執(zhí)行者聯(lián)系在一起。如: It39。s no good eating too much fat. It39。s no good for you to eat so much fat. ②動名詞結構作主語,可以用名詞或代詞屬格形式作邏輯主語。如: It39。s no use your pretending that you didn39。t know the rules. 二、作賓語 ⒈不定式作賓語 ①以下動詞后,只能跟不定式作賓語。如:agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,long,manage,offer,plan,prepare,pretend,promise,refuse,wish等,這些詞大部分可接th at引導的從句。如: I decided to ask for my money back. I decided that I would ask for my money back. When our visit to the farm was over,we expected to startback on foot. When our visit to the farm was over, we expected that wewould start back on foot. ②當復合賓語中的賓語是不定式時,先用形式賓語it代替不定式,把不定式置于補語之后,即:主語+動 詞+it+補語+to do句式。如: We think it quite important for us to learn a foreignlanguage well. He feels it his duty to help the poor. ③介詞but,except,besides+to do(do) 在這種句型中,如介詞前有動詞do,后面應接不帶to的不定式;如無do,則接to不定式,即帶do不帶to, 帶to不帶do。如
