第7章情态动词
7-1情态动词是表示能力、义务、必须、猜测等说语人的语气或情态的动词。
①情态动词与动词原形连用,表示说话人对所说话语的态度和看法。
②情态动词没有人称和数的变化。
③情态动词各种形式一览表:
现在形式 过去时形式
肯定式 否定式 肯定式 否定式
can cannot (can’t) could could not (couldn’t)
may may not (mayn’t) might might not (mightn’t)
shall shall not (shan’t) should Should not (shouldn’t)
will will not (won’t) would would not (wouldn’t)
dare dare not (daren’t) dared dared not (daredn’t)
must must not (mustn’t) had to had not to (hadn’t to)
ought to ought not to (oughtn’t to)
need need not (needn’t)
used to used not to (usedn’t to) didn’t use(d) to
④除表中所列的情态动词外,本书将 have to, had better, would rather, be going to, be to, be about to等也都列为情态动词。
⑤can的否定式一般皆用 cannot, can not多用于否定not后面的词语。但美国英语的 can not往往等于 cannot.
⑥缩 mayn't略式只限用于英国英语,且比较少见。
7-2 “must + have + 过去分词”表示对过去事情的推测。
①仅用于肯定句中,表示说话人对过去发生的行为的推测,意思是“一定曾、准是…了”。
[例] I didn' hear the phone. I__________asleep.
A. must be B. must have been C. should D. should have been
答案是B。“我没有听见电话铃声,那时我一定是睡着了。”A意为 “现在我一定睡着了。”C意为“现在我应该睡着。”D意为“那时我本应该睡着了(其实却没睡着)。A、C、D都与句意不符。
②本结构的否定形式不能用mustn't, 而要用can’t或 couldn't [参见7-3]。
③本结构在变成反意疑问句时,其疑问尾句中不可使用must,而是要根据具体的时间概念,采用didn’t或 haven't to。
[例] He must have studied English last night, didn’t he “昨晚他一定学英语了,是吧 ”
因为有last night这个表示确定的过去时间状语,可知所述动作发生在过去,要用过去时。
[例] He must have studied English for years, hasn’t he “他一定学了多年英语了,是吧 ”
因为有 for years表示一段时间的状语,可知谓语动作在过去发生,并一直延续至今故用现在完成时。
7-3 can或 could + have + 过去分词”表示对过去某事的否定的或疑问的推测。
①这种结构只能用在否定句和疑问句中。肯定句中常用“must”[参见7-2]。
[例] -------There were already five people in the car but they managed to take me as well.
--------It ________a comfortable journey.
A. can't be B. shouldn't be
C. mustn't have been D. couldn't have been
答案是D。“一车里已有五人,但他们还是设法带我同行。” “那么,这趟旅行一定不会舒适了。”must不用于表否定推测,排除C。
而A和B都意指“现在”,与句意不符,故可排除。
②这种结构中的can和 could都用来表示过去的可能性,“时间”上没有区别。但“语气”上有区别: could的“可能性”、把握性”要小于can若上例中的
空白改用“can’t have been,”则口气更为肯定。
7-4 should或ought to + have +过去分词表示该做而实际上未做到, 意为“早该…”,“本该…”。
①在肯定句中,这种结构用来表示过去应该做(或值得做)而没有做的事情。
[例] We ________ last night, but we went to the concert instead.
A. must have studied B. might study
C. should have studied D. would study
答案是C。“昨晚我们该学习,但却去听音乐会了。”说话人对昨晚没有学习表示后悔,有自责的含义。答案A、B、D不合句意,应排除。
②在否定句中,这种结构表示因出了某种差错而带有非难或不太赞许的口吻,意为“不该做而实际已做了某事”。
例】 You shouldn't' have told her the sad news. “你本不该告诉她这悲伤的消息。”
③在这种结构中, ought to比 should的口气更强烈。
[例] She ought to have helped you a lot“她本该给你更多的帮助。”
[例] Tom ought not to have told me your secret, but he meant no harm. “汤姆本不该把你的秘密告诉我,但他没有恶意。”
7-5“may或 might + have + 过去分词”表示对过去某事作可能性推测。
①该结构中的 might与may的意义基本相同,只是它表示的可能性比may表示的可能性更小些。
[例] He is late. He might have had an accident.他迟到了。或许他出了意外。”
[例] You may have noticed some birds sitting on the backs of sheep.“你想必已注意到有些鸟停靠在羊背上
②“might + have + 过去分词”常用于虚拟语气,表示对过去本来可能做而实际上没能做某事的一种责备或遗憾。
[例] He ________you 'more help, even though he was very busy.
A. might have given. B. might give
C. may have given D. may give
答案是A。“即使当时他很忙,他本来会给你更多的帮助的。”B、C、D不合题意,应排除。
③“might + have + 过去分词”用于主语是第二人称的句子,表示“本可以
而没…或具有委婉的责备之意。
[例] You might have come earlier.你本可以来的更早些(但却没有)。
[例] You might not have left the key in the office.你本可不把钥匙留在办公室里的。
④”may + have + 过去分词”通常只用于肯定句或否定句,一般不用于疑间句。在疑问句中通常用can表示.
[例] -----Can they have found the radio
------yes, they may have.“他们可能找到收音机了吗 ”“是的,他们可能找到了。
⑤句中主要动词如果是现在时,间接引语中用句型may + have + 过去分词或 might + have + 过去分词均可。但如主要动词是过去时,则间接引语中只能用句型 might + have + 过去分词。
[例] We thought you might have had an accident or forgotten the day or something. “我们当时以为你也许出了事,或忘了日期什么的。”
7-6“needn't+have+过去分词”表示做了不必要做的事”意为“本可不必”。作为情态动词的need在这一结构中一般只用于否定句或疑问句。
[例] There was plenty of time. She ___________.
A. mustn't have hurried B. couldn't have hurried
C. must not hurry D. needn't have hurried
答案是D。“时间很充裕,她本可不必慌忙。”排除A是因为must + have+过去分词”在表示对过去事情的推测时,只能用于肯定句中,在表示否定推测时,其否定形式是can't(或couldn't)+have+过去分词”。B、C都不符合句意故排除。
注:“needn't have+过去分词与didn't need”的意思不同,试比较:
[例] She needn't' have come to see me yesterday. “昨天她本可不必来看我。”(实际上来看了)
[例] She didn't' need to come to see me yesterday.“昨天她不需来看我。”(实际上没来看)
7-7 表“能力”可用can或 could. can 表示现在或将来的能力; could表示过去或过去将来的能力。
[例] Robert and Joanna cannot see their friends. “罗伯特和乔安娜看不见他
们的朋友。(表身体的能力)
[例] A computer _______think for______itself; it must be told what to do.
A. can't B. couldn't C. may not D. might not
答案是A。“电脑本身不能进行思维活动,它需要指令才能工作。”(表技能)
[例] We couldn't' eat in restaurant because none of us had any money on us.
“我们不能到饭店进餐,因为我们谁也没带钱。”(表做事的能力)
注:用 could询问“现在”是否具有某种能力显得比can客气些,还可用do.
[例] Could(Do) you speak Chinese “您讲中文吗 ”
7-8 “cannot help + V.-ing表示 “不得不”、“忍不住”, 这种结构没有相应的肯定结构。
[例] People couldn’t help ________the foolish emperor in the procession.
A. laugh at B. to laugh at C. laughing at D. laughing on
答案是C。“人们对游行队伍中的愚蠢的国王不禁放声大笑起来。”
7-9 can与 be able to的区别
①在表示过去时的一般疑问句和肯定句中,含有“终于有可能”、“好不容易”、“总算”做成某事之意时,用was/were able to,而不用 could。但在否定句中,两者却可互换使用。
[例] The fire spread through the hotel very quickly but everyone _______get out
A. had to B. would C. could D. was able to
答案是D。“大火很快燃遍了整个饭店,但大家总算都逃了出来。”其余答案均不合题意。
②can只有现在式和过去式(could)两种形式;而 be able to除现在式和 过去式之外,还有将来式、完成式。它还可用作非谓语动词短语。
If you visited Indianapolis you would be able to find your way around easily because most of the streets cross each other like a chessboard. “如果你到印弟安那波利斯游览,你会很容易找到自己要走的路线的,因为大多数的街道像棋盘似地纵横交错。”(条件式虚拟语气)
本句中的“would be able to”是主句中谓语的一部分,表示与现在事实相反的设想。
[例] Being able to read in English, he soon found out their secrets.因为他能用英语阅读,他很快便发现了他们的秘密。” 句中 being able to为现在分词短语,作原因状语。
③can既可用于人,又可用于其他事物作主语的句子中; be able to只用于有生命的名词或代词作主语的句子中
I can hardly imagine Peter sailing across the Atlantic Ocean in five days.“我几乎不能想象彼得在五天内横渡大西洋。”
[例] It can be inferred from the text that the teacher from Guangdong province felt proud of the gold medal winners.“从课文中可推断出来自广东省的那位老师对金牌获得者感到很自豪。”
④带can的主动式结构的句子可变成被动式结构,但带 be able to的主动式结构的句子不能变成被动式结构的句子。
[例] We can use coal to produce electricity for agriculture and industry.“我们能用煤为工农业生产发电。”
本句可变为:
[例] Coal can be used to produce electricity for agriculture and industry.“煤能用来为工农业生产发电。”
⑤在 be able to之前可加一个其他情态动词(但要注意没有 can be able to这样的结构)或把be改为某些系动词 (如seem, turn, look), 而can则不能这样。
[例] I ought to be able to run an English study class.“我应该能办一个英语学习班。”
[例] He seemed able to find-ways- to get out of the trouble“他似乎有能力找到摆脱困境的方法。”
7-10 can, may, could might用于主语为第一人称的句子,征求许可或给予许可,作 “我可以吗 ”解。 “Can I…” 属非正式用法, “May I … ” 属正式用法。
[例] Good morning. Can help you
“早上好。我可以帮你的忙吗 ”
[例] ----- Could borrow your dictionary
-------Yes, of course you_________.
A. might B. will C. can D. should
答案是C。“我可以借你的字典用一下吗 ”“是的,当然可以。”
[例] Hello. May speak to Zhao Hua “你好,我可以跟赵华说句话吗
7-11在会话中可用 could和 might征求许可,表示客气;但给予许可时,通常不用 could或 might, 而用may或can或其它表示客气的词语。
[例] Do you think I could borrow your dictionary
A. Yes, you may borrow. B. Yes, you could.
C. Yes, help yourself. D. Yes, go on.
答案是C。“我可以借你的字典用一下吗 ”“好吧,请便”
7-12主语为第二人称时,“你…可以吗 ”中的“可以”只能用can和 could.
请求听话人答应支持或帮助,不能用may或 might
[例] Can you get me a pencil 你可以给我拿支铅笔吗
[例] Could you help me to move the table 你可以帮我搬一下桌子吗 ”
[例] You can't' park here.(布告牌用语)“此处不准停车。
7-13表示“可能”,可用can, could或may, might
①can, could, may, might都可在肯定句中表“可能”,can的语气最强,可能性最大,其余依次递减。
例] She is very weak. She can easily get tired“她非常虚弱,极易疲劳。”
[例] ----- I stayed at hotel while in New York.
------Oh, did you You ________ with Barbara.
A. could have stayed B. could stay
C. would stay D. must have stayed
答案是A。“在纽约时我住在一家旅馆里。”“哦,是吗 那你可能和芭芭拉在一起啦。”因为是谈过去事情的可能性,情态动词后要加不定式的完成式,排除B和C。
又因上文“Oh, did you ”表明应答者对前者说的事情不太了解故而下文要选用把握不大的推断词 could (= to say that something would or might be possible),而不用有绝对把握的推断词must(=to be, do, ect, very probably or certainly).
[例] Peter _________come with us tonight, but he isn't very sure yet.
A. must B. may C. can D. will
答案是B。“彼得今晚可能跟我们一道来,但他还不很肯定。”
[例] I thought you _________like something to read, so I have brought you some books.
A. may B. might C. could D.must
答案是B。“我想你也许想读点什么,所以我给你带了几本书来。
②在肯定句中can往往表示“理论上可能”,may往往表示“事实上可能。”
[例] The road can be blocked up.“这条路可能堵塞。”
[例] The road may be blocked up.“这条路可能堵塞了
7-14 can, could, might表示可能性,可用于疑问句,而may则不可。
[例] Could this be true 这可能是真的吗 ”
7-15 can, could, may, might表示“可能用于否定句时,后面的否定词否定的范围不同:can或 could后面的否定词否定can或 could; may或 might后面的否定词不是否定may或 might,而否定否定词后面的不定式。因为否定词否定的范围不同,所以can, could, may, might用于否定句表示可能时含义也各不相同。试比较:
[例] He can't be in the classroom.他不可能在教室里。”
[例] He may not be in the classroom“他可能不在教室里。”
[例] He could not be honest.“他不可能诚实。”
[例] He might not be honest. “他可能不诚实。”
7-16 will, would, can, could都可表示“请求, 但用 would, could比用will, can语气更委婉,更客气。
[例] Will you do me a favour, please 请你帮我一下好吗 ”
注: 这句话也可改成:Won' t you do me favour 用“won’t you.”较“Will you.”显得更客气些。
[例] I will be away on a business trip. Would you mind looking after my cat “我要出差,请你照料一下我的猫好吗?
[例] Can you lend me hand “你能帮我一把吗
[例] Could you give me a hand with the cooking“你能帮我烧饭吗
7-17 shall和will都能作情态动词表示“意志”. 表“意志”时, shall和will的根本
区别是: shall表示说话人的意志,而will则表示句子主语的意志。
①表示强烈意志
[例] Father will not allow us to use his recorder. “爸爸就是不让我们用他的录音机。
[例] No one shall stop me from doing this.“谁也无法阻止我这样做。”
shall所表示的说话人的一种强烈意志,有“命令、警告、威胁、强制”等含
义。因此shall的这种用法只适宜于第二和第三人称。will表示的是句子主语的
意思,它可以用于所有人称。
在表示强烈意思时, shall和will都要重读,都不能用其缩略形式
②表示一般程度的意思
在表示一般程度的意思时,说话人也完全可以对自己表示此类意思,因此shall也可用于第一人称,这样,说话人同时也是句子的主语, shall和will的意思趋于一致。
[例] We shall/will let you know our telephone numbers.我们会让你们知道我们的电话号码。
[例] I shan''t/won't' lend you the money.“我不会借给你这钱的。”由于表示的是一般程度的意志, shall和will不必重读,也可以用其缩略形式’ll.
7-18主语若为无生命的东西,won’t不表示意志, 而意为“不起作用,”“就是不……”
[例] -----Can help you, sir
-------Yes, I brought this radio here yesterday, but it________
A. didn't work B. won't work C. can't work D. doesn't work
答案是D。“先生,您要什么 ”“是这样,昨天我在这买了这台收音机,现在(答案D)它不响/ (答案B) 它就是不响”。
7-19用“情态动词would或 used to+动词原形”表示过去的习惯
① used to强调与现在对比,含有“过去如此而现在已不如此”之意而would 则没有此意。如:
[例] Mother_______ us stories when we were young.
A. was used to tell B. is used to telling
C. used to tell D. used to telling
答案是C。“小时候,妈妈常常给我们讲故事。”
[例] Sometimes after supper Mother would sit under the tree and tell us stories.
“有时候,晚饭后妈妈就会坐在树下给我们讲故事。”
② used在后面可接表示状态的动词,含有“过去一向…之意,而would则一般不能这样用。如:
The social clock that, kept us on time and told us when to go to school, get a job or stop working isn't as strong as it used to be.“使我们准时,并告诉我们何时上学,何时找工作或何时退休的社会钟现在不像过去有力了。”
③ used to用于表示过去有规则的习惯,而 would表示过去不规则的习惯。
[例] I used to play ping-pong a lot in my spare time, but now am interested in football.过去在业余时间里我常常打乒乓球,但现在我对足球感兴趣。”
[例] He would often come to see me when was living in the country我在农
村生活时,他常来看我。”
④ would含有主观的感彩,即表示自觉的行为和动作;而used to只 表示过去的事实,比较客观,试比较:
[例] She would help me with my English on Sundays.“星期天时,她会帮我学英语。
[例] The antient Egyptian kings used to build pyramids as tombs.“古埃及的国王们过去建造金字塔作为自己的陵墓。”
7—20 should, ought to, would, will, 表示推测或推断它们的语气依次 递增。
[例] It's nearly seven o’clock. Jack __________
A. must B. need. C. should D. can
答案是C。“快7点了。杰克随时都有可能到这儿来。should在这里表示推测。
[例] —When can I come for the photos I need them tomorrow afternoon.
— They______ be ready by 12: 00.
A. can B. should C. might D. need
答案是B。“什么时候我可以来取像片 明天下午我要用。到12点钟就洗好了。”should (约等于will probably) 表示推测“可能”。而can (约等于to be able to) 表示“能够”、“可以"; might(约等于to be in some small degree,likely to),表示把握不太大的“也许”、“或许”; need表“需要”。
[例] They ought to arrive home by now.他们现在就该到家了。”
句中 ought to表示推测,其语气较 should强。表推测时,ought to 有“很可能”之意。
[例] Go and ask Mary. She ought to know his address.去问问玛丽。她该知道他的地址。
[例] It would seem that something is wrong with this radio.“看来这台收音机出毛病了。”
句中的 “would+动词原形”表示对现在或将来的婉转的推测,意为“大概…,可能……,似乎…”
[例] I guess the poet would have been about twenty when she wrote her first poem.“我猜想这位诗人写第一首诗歌时,大概是20岁左右。”
句中“would + 动词完成式”,表示对过去情况的推测。
[例] You will remember my father.“你大概记得我的父亲吧。”
在本句中will表示说话人的主观推测,意为“大概”
注:will表示推测时,句子的主语通常是第二和第三人称。
[例]That, think, will be all that want'' to say. “我要讲的话,我想就是这些吧。”
[例] I was sick all night. I think it must be the fish I ate last night. “我难受了整整一个晚上,我想毛病一定出在昨晚我吃的鱼上”
句中的must表达说话人对句子主语的推测,表示确信或有很大的可能性。must和动词原形连用是对现在情况的推测;和动词完成时 连用是对过去情况的推测。
[例] She must have been very pretty when she got married.
“她结婚时一定很漂亮。”表推测的must只能用于肯定句,否定和疑问结构须用
can; 如: The door is locked, he can't' be at home.“门锁 着,他一定不在家。”
[例] You must be joking“你一定是在开玩笑吧。” must表推测,可用进行时。
7-21 shall, should用于第一人称,表征求对方的意见。
[例] When shall we meet again “我们何时再见 ”
[例] What should we do now “我们现在该做些什么 ”
在征求对方的意见时,用should比用 shall更具试探性。
7-22 should, would用于表示委婉的愿望。
[例] Little Jim should love to be taken to the theatre this evening.“小吉姆今晚想
让人带着去看戏。
[例] I would appreciate your calling back this afternoon. “今天下午你能回电话,我会 感激的。”
7-23 would rather表示主观意愿后接不带to的动词不定式意为“宁愿”。
[例] I would almost rather see you dead“我宁愿看见你死去”。
would rather + 不带to的动词不定式”结构中的 would可以换成had,但would rather更常用。 would(had) rather (通常缩写成 'd rather.)
[例] I'd rather go out this evening今晚我宁愿出去。”
7-24 would rather与than连用,其结构是: would rather …than…
或 would.... rather than…; 也可以颠倒为: rather than…, would.... 。would(rather)和than后都接不带to的动词不定式, 如用的动词相同,则than后省略动词。 would rather…than…, 意为“宁愿…而不愿,与其…宁可…等
[例] I ______ play football than baseball.
A. would rather B. had better C. like better D. prefer
答案是A。“我宁愿踢足球而不愿打棒球。”
[例] Rather than make money in such dishonest way, John would beg in the street约翰与其用这种不诚实的方法赚钱,他宁可在街上乞讨。”
7-25 would rather的否定式是把否定词not放在 would rather和不带to的动词不定式之间;疑问式是把would放在主语之前。
[例] —Shall we go skating or stay at home
—Which __________ do yourself
A. do you rather B. would you rather
C. will you rather D. should you rather
答案是B。“我们是去滑冰还是呆在家里 ”“你自己愿意做什么
[例] would rather not tell you“我宁愿不告诉你。”
7-26表示“必须”这个意思时,must多表示主观意志, have to则往往强调客观需要。
[例] You must eat more.你须多吃点。”
[例] The train leaves at 6:00 pm. So I have to be at the station by 5:40pm at the latest.“火车下午6点启程。所以我最迟必须在5点45分到达车站。”
7-27 must只有现在时形式,通常用以表示现在,过去时形式经常用 had to 来代替; have to除了 had to的过去时形式外,还有将来时和完成时形式。
[例] —Must I do it now
—Not if you don't want to.
“我必须现在做吗 ”“不,如果你不想的话。”
[例] They expected that they would have to go to bed hungry.他们预料他们将要饿着肚子上床睡觉了。”
[例] I decided that I must stop smoking.“我决定我必须停止吸在间接引语中,往往用must表示过去。
7-28 must用来表示“必须时,它的否定形式是 need not (不必…没有必要;缩略形式是: needn't) 不是 must not (mustn't ; have to的否定 形式是do (does,did) not have to。
[例] —Shall I tell John about it
—No, you_______. I' ve told him already.
A.needn’t B. wouldn't C. musn't D.shouldn't

[例] You must not eat chocolate你不要吃巧克力了。”
答案是B。“约翰尼,你不要玩刀子,会伤着你自己的.
7-30 ought to和 should两者都可表示“应该”,但 ought to比 should语气强些。
[例] You ought to go and see the pyramids你应该去看看金字塔。”
ought to往与 should同义,在生活交际中人们多用后者。但有时ought to有针对性, should则表一般的忠告,试比较:
[例]Tom' s mother told him that he ought to work harder the next term.“汤姆的妈妈告诉他下学期学习应该再努力些。”
Tom's mother kept telling him that he should work harder, but it didn't help.“汤姆的妈妈一直在给他讲他应该在学习上再下些功夫,但就是没用。
情态动词 ought to有进行时与完成时。

7-31 ought to的否定式和疑问式

—“Yes, you ought.“当然,你该去。”
[例] They ought to go, oughtn't they 他们该去,不是么 ”
7-32 had better是固定词组,作情态动词使用,意思是:“最好…”, “还是…好”。缩写形式是接: ’d better.
① had better要求接一个不带to的不定式。
[例] If you plan to control your life, you'd better win your parents over and try to get them to understand you.“如果你打算主宰自己的命运,你最好把父母争取过来,尽量让他们理解你。”
② had better否定式是: had better not. 如:
You had better not wake me up when you go. “你走时最好别叫醒我。”
③ had better有自己的被动语态,其结构是: had better + be +过去分词:
[例] The flowers had better be watered“花最好浇一下
had better中的had尽管是以have的过去形式出现, 但它所表示的却是现在或将来的事情。
7-33 dare用作情态动词表示“敢”,通常用于否定句和疑问句,其过去式形式是 dared.
