2018届 二轮复习 动词不定式考点练与析 1.动词不定式的句法功能 (1)不定式作主语 To know something about English is one thing;to know English is quite another. 此时,常用it作形式主语,而把不定式放在句子的后部。 It isn’t easy for her to find a new job. (2)不定式作宾语 ①不定式可作某些动词的宾语,常见的动词有:afford, agree,ask,decide,desire,expect,fail,hope,manage, promise,pretend,plan,intend,refuse,wish等。 I promised not to be late. ②介词but/except后接不定式作宾语时,如前面有实义动词do, 不定式就要省略to。 It has no choice but to lie down and sleep. They did nothing but complain. (3)不定式作宾语补足语 ①某些动词如tell,want,wish,advise,order,require,expect, remind,persuade,encourage,convince,force,beg,allow, forbid等后可接不定式作宾语补足语。 My doctor advised me to take a rest. ②某些感官动词如feel,hear,see,watch,notice,observe等或使 役动词如have,let,make等后面可接不带to的不定式作宾语补足语。 但如果句子变成被动语态时,就必须带to 符号。 Did you notice anyone go into the house? Was anyone noticed to go into the house? ③某些动词如find,feel,think,expect,consider,make等后可接不定式作宾语, 但宾语后要接形容词或名词作宾语补足语,而且要用it作形式宾语。 News services make it possible for newspapers to give their readers news from around the world. (4)不定式作定语 Do you have the ability to read and write English? ①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是不定 式动作的地点、工具等,不定式后面须有相应的介词。 Please give me a knife to cut with. ②不定式作定语一般表示将来的动作,但修饰有序数词或形容词最高级 限定的名词时,则表示已完成的动作。 I borrowed some books to read during my holiday. She was the first woman to win the gold medal in the Olympic Games (5)不定式作状语 ①不定式一般作目的状语,还可用短语in order to 或so as to。 He sat down to have a rest. ②不定式有时可作结果状语,表示意想不到的结果,还可用only to。 He left,never to return. He lifted a stone only to drop it on his own feet. ③不定式可用在下列句子中表示结果: He was so careless as to forget to lock the door. ④不定式可作评注性状语,用以修饰整个句子。 To be honest,I know nothing about it. (6)不定式作表语 The first step is to check the victim’s breathing. All I did was (to) press the button. (7)“疑问词+不定式”在句中可充当主语、表语、宾语。 When and where to hold the meeting is not known yet. I didn’t know whether to laugh or cry about it. 【注】 此时不可用if to do结构。 2.不定式的时态和语态 时 态 主动语态 被动语态 一般时 to do to be done 进行时 to be doing 完成时 to have done to have been done (1)不定式的时态 ①不定式的一般式表示将来要发生的动作或表示一种状态。 I wish to finish my business and get away. He pretended to be asleep when his mother came in. ②不定式的进行式表示不定式动作仍在进行之中。 It happened to be raining hard when the accident occurred. ③不定式的完成式表示不定式动作已完成或发生在句子的谓语动词之前。 He is generally considered to have invented the telephone. (2)不定式的语态 当不定式与自己的逻辑主语之间是主动关系时,用主动语态;如果是被动 关系则用被动语态。 He refused to go abroad. He refused to be taken abroad. 【注】 下列情况下不定式用主动形式表达被动意义: ①不定式作定语时。 She has a sister to look after. ②不定式放在形容词之后时。 This book is difficult to understand. ③个别动词用在“be+不定式”结构中表将来或应该时。 I think he is to blame.我认为他应该受到责备。 3.不定式的省略问题 有时为了避免重复,不定式可用省略形式,但常常要保留不定式符号to。 这种情况常出现在动词expect,hope,wish,mean,prefer,care,forget, want,try或be glad,be happy或would like/love等后面。如果不定式中含有 be,have,have been时,这些词也可保留。 I haven’t been to Hong Kong,but I wish to. “I didn’t tell him the news.”“Oh,you ought to have.” 二、动名词 1.动名词的功能 (1)动名词作主语 Watching them is a thrilling experience. 【注】 有时用it 作形式主语,而把动词的ing 形式放在句子的后部。 It is no use crying over spilt milk. (2)动名词作宾语 ①下列动词后只能接动名词作宾语,不可接不定式作宾语:admit, appreciate,avoid,consider,delay,dislike,enjoy,escape,excuse, finish,imagine,keep,mind,miss,practise,risk,resist,suggest等。 I admit breaking the window. ②下列短语后要接动名词作宾语:burst out,can’t stand,end up,give up,feel like,keep on,insist on,look forward to,put off,devote...to, object to,be busy(in),get down to,have difficulty/trouble(in),have a good/wonderful/hard time(in)等。 He didn’t want to end up going home alone. ③下列动词或短语后接不定式和动名词作宾语时,意义上有所不同。 Remember to post the letter for me on your way to school. 请你在上学的路上记住替我把这封信寄出去。 I remember turning off the light before I left the office. 我记得在离开办公室前关上了灯。 ④动词like,love,prefer,hate,continue等后接不定式或动名词作 宾语均可。但如表示经常性的动作要用动名词,如表示具体的行 为要用不定式。 I like swimming,but I don’t like to swim this afternoon. ⑤动词allow,advise,forbid,permit等后接动名词作宾语,但要接 不定式作宾语补足语。 We don’t allow smoking here. We don’t allow students to smoke. ⑥动词need,require,want作“需要”解时,其后要用动名词的主 动语态或不定式的被动语态作宾语。 The window needs cleaning/to be cleaned. ⑦形容词worth后要接动名词的主动语态表达被动意义,它不同于 worthy 的用法。 The place is worth visiting. The place is worthy of being visited/to be visited. ⑧介词后要接动名词作宾语。 What do you mean by saying that? I congratulated them on getting married. (3)动名词作表语 My hobby is growing flowers. (4)动名词作定语 He had a very expensive walking stick. 2.动名词的时态和语态 主动语态 被动语态 一般时 doing being done 完成时 having done having been done He went away without saying anything. He came into the room without being seen. I’m sorry for having wasted so much of your time. I forgot having been given a Christmas gift years ago. 3.动名词的复合结构 动名词之前有时要加上自己的逻辑主语构成复合结构,逻辑主语可用 名词的所有格或物主代词,有时也可用名词或宾格代词。 I can’t imagine George sailing across the ocean in a boat. My coming back home late made my mother very angry. 三、分词 1.现在分词的功能 (1)现在分词作宾语补足语 下列动词后可接现在分词作宾补:see,hear,notice,observe, watch,listen to,look at,have,keep,leave,find,catch,feel等。 She kept me waiting for over 20 minutes. 【注】 如果句子改为被动语态,那么现在分词则变为主语补足语。 The boy was caught cheating in the exam. (2)现在分词作表语 The movie is very boring. (3)现在分词作定语 现在分词作定语时,通常表示与先行词之间是主动关系。 The taxi taking us to the airport broke down. 【注】 being done形式表示正在进行中的动作,且与先行词之间是被 动关系。 The house being built will serve as a library. 正在建的那座房子将作为图书馆用。 (4)现在分词作状语 ①现在分词作状语时,可表示时间、原因、结果、条件、让步、行为方 式、伴随状况等。此时,现在分词的逻辑主语通常就是句子的主语,而 且现在分词与句子的主语之间一般具有逻辑上的主谓关系。 The cup dropped to the ground,breaking into pieces. Jack came running over. 【注】 如果现在分词的逻辑主语不是句子的主语,就要用分词的独立 主格结构。 Weather permitting,we’ll play golf this afternoon. We explored the cave,Peter acting as a guide. ②现在分词还可作评注性状语,表示说话人的态度,此时现在分词与句 子的主语无关。常见的说法有:generally speaking“一般来说”;frankly speaking“坦白地说”;judging from...“根据……来判断”; considering...“考虑到……”等。 Considering the distance,he arrived very quickly. 2.现在分词的时态和语态 主动语态 被动语态 一般时 doing being done 完成时 having done having been done Not knowing her address,I wasn’t able to contact her. I saw him being taken away when I passed by his house. Having bought our tickets,we went into the theatre. Having been told many times,he still repeated the same mistake. 3.过去分词 过去分词一般在句中作宾补、表语、定语和状语,通常表示已完 成的被动动作或一种状态。 You’d better have the television repaired. Some of the people invited to the party can’t come. The teacher came into the lab,followed by some students. Given a chance,I can surprise the world. He stood in front of the room with his arms folded. 四、不定式被动式、过去分词和现在分词的被动式作定语 1.过去分词表示的动作或是在谓语所表示的动作之前发生,或是没有一 定的时间性。 Have you read the novel written by Dickens? 2.现在分词的被动式作定语时表示的动作正在发生或是与谓语动词所表 示的动作同时发生。 Listen!The song being sung is very popular with the students. 3.不定式的被动式作定语时,表示一个未来的动作。 The question to be discussed at tomorrow’s meeting is a very important one. 3.have,get后接三种形式作宾补时,其中have,get表示“使、让、 叫”之意。 (1)have sth.done=get sth.done“使/让某事由别人去做”。 I’ll have/get my bike repaired tomorrow. 【注】 have sth.done还表示“使遭受……”之意。 Tom had his leg broken while playing football. (2) The peasants had the tractor working day and night at the harvest time. The captain got the soldiers moving toward the front after a short rest. 【注】“have sb. doing”若用于否定句中,其中have有“容忍”之意。 I won’t have you speaking to your parents like that. 五、分词、不定式作宾语补足语的区别 1.感官动词(see,watch,observe,look at,hear,listen to, notice等)和使役动词have后面的宾补有三种形式,即原形动词(不带 to的不定式),现在分词和过去分词。现在分词表主动或正在进行, 过去分词表被动或完成,动词原形表主动和完成。 I heard her sing an English song just now. 刚才我听见她唱了一首英文歌。 I heard her singing an English song when I passed by her room yesterday. 昨天经过她房间时,我听见她在唱英文歌。 I heard the English song sung many times. 我多次听到有人唱这首英文歌。 2.leave后接三种形式作宾补时,意为“使……处于某种状态”。 (3) “使/让/叫某人去做某事” Mother had me go to the shop and buy some salt.
