《非谓语动词练习》PPT课件

非谓语动词性质：它具有动词的特点，但在句子中起着名词、形容词、副词的作用，充当主语、表语、定语、宾语、宾语补足语、状语的作用，即：除谓语以外一切成分。 过去分词不定式非谓语动词动名词现在分词 主语 表语 宾语 定语 补语 状语 不 定 式 动 名 词 现 在 分 词 过 去 分 词 动词不定式的基本形式 主 动 语 态 to do 被 动 语 态一 般 式进 行 式完 成 式 to be doneto be doingto have done to have been done 动词不定式To do that sort of thing is foolish。I want to see you this evening.All you have to do is to finish it quickly.We found a house to live in.She came here to study English. I warned the patient not to eat cold water after the operation. 主语 宾语表语 定语 状语 宾补 例1： To help each other is good._to help each other.互相帮助是好的。例2：_to understand him.我发现了解他很困难。It is goodI find it difficult 不定式在六个感官动词feel, listen to, hear, see, watch, notice, 三个使役动词let, have, make等后作宾补时,to要省略。如例1： Now, let me go.（go前省掉了to）例2：I saw her run into the classroom.（run前的to省掉了）比较She was seen _ the classroom. 例1. The farmers didnt know what to do. The farmers didnt know .例2. Please tell me how to get to the zoo. Please tell me .what they should dohow I can get to the zoo v不定式在以下形容词后:easy, difficult, hard, heavy,light, cheap, expensive, good, nice, safe, dangerous, important, interesting, pleasant, (im)possible, fun等。This question is difficult _ (answer).Do you think him easy_ (work) with?v这时用主动形式表被动意思。 动词不定式省略to 的情况归纳*1 当动词不定式作宾语补足语时，如动词是 make, let , have 或 look at , see, watch, observe, hear, listen to, feel 、等，不定式不带to.*2. 在下列结构后 had better, would rather, would ratherthan, cannot but（不得不 ，必然，不能不）, cant help but 等*3. Why. 或 why not 表建议4. 在介词 but , except 之后，如果其前有 实义动词do 的某种形式，不定式不带to,反之须带to .（记忆口诀）*5 不定式作表语时，如果be动词前有do/did/does时，to可以省去。 注意1：不定式动词在介词but，except，后面时，如果这些介词之前有行为动词do的各种形式，那么，这些介词后的不定式不带to，否则要带to。 She could do nothing but _(cry) I have no choice but _(go) 注意2：作定语的不定式如果是不及物动词，或者不定式所修饰的名词或代词是不定式动作的地点工具等，不定式后面须有相应的介词。 He is looking for a room _(live) There is nothing (worry)Please give me a knife (cut)to live into worry aboutto cut with 注意3：当作定语的不定式所修饰的名词或代词是不定式动作的承受者时，不定式既可以用主动语态，也可用被动语态，但其意义有所不同。 比较： A) Have you anything to send? B) Have you anything to be sent?你有什么东西要寄吗?(不定式to send的动作执行者是you)你有什么要(我或别人)寄的东西吗?(不定式to be sent的动作执行者是已被省略的me或someone else) 作简短回答或避免不必要的重复时，动词不定式常常省去to 后面的动词，只保留to 。A:Would you like to come to my party?Mary wanted to use my bike, but I asked her not to ( use my bike).B: Yes , Id love to ( come to your party).Mary想用我的自行车，但我叫她别用。 不 定 式 的 时 态 要 重 视例1 NMET 1997第12题I would love _ to the party last night but I had to work extra hours to finish a report. A. to go B. having gone C. going D. to have gone 例2 NMET 1999 第14题Robert is said _ abroad, but I dont know what country he studied in. A. to have studied B. to studyC. to be study D. to have been studying (1)如果谓语表示的动作(情况)发生时，不定式表示的动作正在进行，这时不定式就要用进行式。 Tom and Martin pretended _their homework when the teacher came into the classroom. （假装正在做作业）(2)如果不定式的动作发生在谓语动词之前，要用完成式。 She is said _thirty novels this year.据说她已读了30本小说。 to be doingto have read 不定式的语态不应忽略当不定式的逻辑上的主语是这不定式所表示的动作的承受者时，不定式一般要用被动形式。不定式的被动形式有两种：一般式和完成式。1.It is an honor for me _to your party. (invite)2.After graduation, he asked _to work in the countryside. (sent)3.This novel was said _into French. (translate)4.He was the first student_by The teacher. (punish) to be invitedto be sentto have been translatedto have been punished 主 动 形 式 被 动 形 式一 般 式 doing being done完 成 式 having done having been done .a. Its no use sending him over. Its too late already. Its no good talking a lot without doing anything. Its a waste of time arguing about it.b. Theres no joking about such matters. Theres no saying what hell be doing next. Theres no telling what hes going to do.而在Its important / Its necessary 这类句型中，只能用不定式如： Its important to learn foreign languages. Its quite necessary to read it many times. 在need, want, deserve等后，可用动名词的主动式表示被动含义，或用不定式的被动式，意义上无差别。但用动名词较为普遍，（这时主语一般是物），如： The door needs_.(paint)painting / to be painted. 如：I regret _her advice.(我后悔没听她的建议）如：He did it without_.(ask)The little boy didnt mind _(leave) .They couldnt stand _(treat)like that.not having takenbeing treated 有时为了明确动名词所表示的动作的执行者，可以在动名词之前加上一个或，来表示动名词逻辑上的主语。有时也可以用人称代词宾格或名词普通格，不过，这主要用于口语中。如： She wont hear of . Do you object to ?注：如果不是在句子的开头，这个结构常用名词的普通格或人称代词宾格，如： I dont like the idea of us / our not helping at all. I dont mind Jane buying another one.注：如果动名词的逻辑主语是表示无生命的东西的名词，或不定代词，就只能用普通格，不能用所有格，如： Is there any hope of your team winning the match? The boy was alarmed by someone knocking at the door. 1.Do you mind opening the door? （我）2. Going there saved us a good deal of trouble. （Tom）3.Being late again made the teacher angry. （他）Do you mind me/my opening Toms going there saved us a good His being late again made 1. _to the meeting surprised all of the boards. A. Mike coming B. Mike came C. Mike coming D. Mikes coming 2. Its no use _ that you didnt know the rules. A. you pretend B. you pretending C. your pretending D. your pretend 动名词与不定式的不同含义： 1)be afraid to do 不敢、害怕、胆怯去 做某事 be afraid of doing 担心、恐怕出现 She was afraid _( wake ) her husband up, for he had bad temper. She was afraid _( of wake ) her husband, for he was ill. 2) forget, remember, try, mean, stop, . 3)permit, allow, forbid ,advise, admit, 4)cant help doing sth. cant help (to )do sth. cant help but do sth.不得不，忍不住1.I couldnt help_(think) of my childhood when I saw the picture.2.Im sorry I cant help_(lend) you the money, for Im short of it nowadays.3.I cant help but_(cry). 分 词分词：分词相当于形容词、副词。作表语、定语、宾语补足语和状语。分词可分为现在分词、过去分词。 现 在 分 词 的 基 本 形 式 doing being donehaving done having been done（只作状语）主动语态被动语态一般式完成式 独立主格结构 （ 所谓独立主格结构，分词的逻辑主语不 是 句 子 主 语 ， 而 是 有 自 己 的 逻 辑主 语时，叫独立主格结构。）A)1. Today _( be ) Sunday, the library doesnt open. =Because today _(be) Sunday, 2. There _( be ) no buses, we had to walk home. 3. The signal _( give ), the bus started.4.
