第12页:虚拟语气和情态动词
  虚拟语气和情态动词   一、虚拟语气   英语中有三种语气;陈述语气、祈使语气和虚拟语气。人们根据说话不同需要采用不同的语气。虚拟语气主要用来表示人的主观和假设的意图,   (一)重点   1虚拟语气三大公式           条件从句    主句   与现在事实相反  if+主语+were(v-ed) 主语+would(should,could,might)+do   〈动词过去式〉   与过去事实相反 If+主语+had done 主语+would(should,could,might)+have done   与将来事实相反 If+主语+should(were to) 主语+would(should,could,might)+do   +do   2动词wish后面的宾语从句中谓语动词的虚拟结构;   与现在事实相反 与过去事实相反   wish v-ed(动词过去式,be用were) had done   I wish I were handsome。   I wish you didn`t fall ill。   She wished she hadn`t said it。   3用于表示意愿、建议、命令等动词后的that宾语从句中;   suggest建议 demand要求   insist坚持 order命令   ask要求 command命令   desire渴望 propose提议   recomment推荐 advice劝告,忠告   decide决定 maintain坚持   object反对 prefer宁可   move建议,动议 urge强调   The doctor suggested that she not smoke。   She insists that she hear somebody in the room。   The law requires that everyone have his car cheched。   I desire she come tomorrow。   They moved that all civilians(should)be evacuated(撤出)。   4、在It is|was+某些形容词或过去分词+that引导的主语从句中常用虚拟语气。   Important重要的 natural自然的   Necessary需要的 orderde命令   Possible可能的 preferable更可靠的   Requested要求的 recommended推荐的   Better较好的 crucial关键的   Desired盼望的 imperative迫切的   Suggested建议性的 urgent紧迫的   Required要求的 vital至关重要的   It is necessary that you should be present at the discussion。   It was ordered that the medicines be sent here by plane。   It is imperative that you arrive in time。   It will be better that we meet some other time。   It has been decided that the meeting(should)be postponed。   It is insisted that he be punished。   上述形式同样也用于下面两类句型中,一般表示遗憾、惊讶之情;   (1It is pity(shame遗憾,incredible难以置信,strange,no wonder)that+should如;   It is strange that she should have failed to see her own shortcoming。   It is incredible that should love her。   (2)I am sorry(surprised,convinced)+should+do(have done)    I am sorry that she should have made him angry。   5、下面一些名词后的同位语或表语从句中,要求用should(可省略)+动词原形表示虚拟。   Advice劝告,忠告 order命令   Demand要求 preference偏爱   Decision决定 proposal建议   Request要求 desire愿望,要求   Requirement要求 idea主意,想法   Suggestion建议 recommendation推荐,介绍   His suggestion is that you(should)attend the lecture。   His sole(唯一)requirement is that the system work(起作用)   Your decision that he should be fined (罚款)is reasonable。   6、虚拟语气的其他几个句型。   (1)It is(about,high)time+从句,表示早该做而未做的事,含建议的意味。其动词形式用过去式。   It is high time(that)we began to work。   咱们该开始工作了。   It is(ahout)time that children went to school。    孩子们该上学去了。   (2)as if (though)引起的方式状语从句和表语从句中,其动词形式与wish宾语从句中的形式相同。如;   She loves the children in the kindergarden as if they were her children。   Alan talked about Rome as if he had been there。   She looked as if (though)she would cry。   注;as if(though)引起的从句有时也用陈述语气,这时它表示较大的真实性或可能性。    It looks as if it is going to rain。   (3)虚拟语气用在“in case”,“lest”,“for fear that”引起的状语从句中表示“以防,以免”。其形式为should+动词原形。如;   He took his raincoat with him in case it should rain。   注;在以上in case类状语从句中的should一般不可省去。但可以用动词陈述语气形式。如;The teacher spoke slowly in case we misunderstood him。   (4)if only连词后谓语动词用虚拟语气,意思为;“要是,倘若是,只要”着重强凋渴望或惋惜。   If only I had money,I would buy a new car。   If only I had not lost money。要是我没丢钱就好了。   If only he could come!我真希望他能来。   二虚拟语气的难点    1、如果条件句中包含有 were,had,should,可以把if省略,把这几个词放到主语之前,构成主谓倒装。如;   Were I you,I would not go。   Were I to meet him tomorrow,I should ask him about it。   Had he worked harder (=If he had worked harder ),he would have succeed。   Had he been more careful (=If he had been more careful),such mistakes could have been avoided。   Should you change your mind (=If you should change your mind),no one would blame you。   2某些介词短语可以代替if从句,如;but ror,without,under,in case of,but that…   But for the storm ,we should have arrived earlier。   Without water ,nothing could live。   We could have done better under more favourable conditions。   3、当条件从句表示的动作和主句表示的动作发生的时间不一致时,动词的形式要根据表示的时间来调整。如。若条件从句表示动作与过去是相反,而主句与现在相反时,从句谓语要用had+过去分词,而主句中要用would(should,could,might)+动词原形,如;    If I had asked for directions,I wouldn`t get lost now。假如我当初问一下路,现在就不会迷路了。(if说的过去,主句说的是现在)   三情态动词   (一)重点   情态动词的重点主要是can,could,may,might,must,have to,need,dare,should(ought to)。Shall,should,will,would….   1、can和could   (1)表示能力或客观可能性。   Can you speak English?   (2)在否定、疑问句中表示怀疑或推测。    Can the news be true?   What he said could not be true。   (3)表示允许或许可。    These days children can do what they like。   You can recite the article now。   (4)can+have+过去分词;在疑问句中表示对过去行为的怀疑或不肯定。    Can he have passed the exam?(怀疑)   (5)cannot(couldn`t)+have+过去分词;表示对过去事情的推测。    They couldn`t have done such things。(推测)。   (6) could+have+过去分词;表示与事实相反。    He could have done the jod,but he refused to。(未实现的行为)   注;could尽管是can的过去时,但有时并不表示过去时,只表示语气上的委婉、客气。如;Could I use your dictionary?   如作肯定回答,要用can或nay,而不用could或might。   2、may和might   (1)表示请求和允许;May(Might)I…?    Might I make a suggestion?    You may use my bike。   (2)表示推测(可表示现在或将来的可能性)“可能“   The story may be interesting。   Do you thing they might come?   (2)may(might)+have+过去分词;表示对过去的推测,认为某一事情在过去“可能”发生。May和might都指过去,might较为含蓄委婉或更加不肯定。    He may(might)have missed the plane。   He may(might)not have met them。   (3might+have+过去分词;表示未实现的行为。   You might have done the work better。   You might have left her earlier。   注;may的否定式为may not or mustn`t,后者语气比较强些。一般用mustn`t代替may not,意思为“不可以”,“不准”等。如;    May I read the book?    Yes,you may 。No,you mustn`t。   3、shall和will   (1shall   A、shall用在主语是第一人称或第三人称的疑问句中,表示说话人征求对方的允诺。如;   Shall I fetch a doctor for you?我为你请医生好吗?   Shall he attend the meeting?要他来参加会吗?   B、shall用在主语是第二人称或第三人称陈述句中,表示说话人的允诺和警告。如:   You shall be sorry for what you have done。   He shall get what he wants。   (2)will   A、表示“意志”“意愿,如;   We will do our best to get the job done in time。   She can stay home if she will。   B、表示“请求”如”;   will you please be quiet?   Don`t be late for the meeting,will you ?   4dare   (1当情态动词用,只能用于疑问句和否定句中。    He dare not it 。Dare he go?   (2当实意动词用,可用于各种句型中。Dare作实义动词用在否定句和疑问句中时,其后接不定式有时可省去“to”如;    Does he dare to come?   She dares to speak before big audience。   I have never dared(to)speak to him。   Did he dare(to)criticize me?   5、had better最好,would rather宁愿   否定式;had better not+动词原形;would rather not+动词原形   疑问式;Had you better….?    Would you rather…?   I would rather go at once。   I would rather not do it。   You had better do it every day。   注;I`d=I would(should)或I had   You`d=you had或You would cannot help+动名词和cannot but +动词原形(都当“不得不”或“不禁”解)。   I cannot help telling him the truth。   She cannot but sing。   (二)难点   1、need有三种用法。   A、need相当普通动词=do,意为require“需要”,“要求”如;   You don`t need to leave so early。   He needs to try one more experiment。   Dose the recorder need repairing?   B、need相当情态动词,只能用于否定句和疑问句中当“需要”“必要”解。可用于现在时和将来时。在宾语从句中可当过去时用,肯定回答用must(或have to,ought to,should)来表达。否定式为need not。Needn`T如;   Need you go yet?Yes ,I must。NO I needn`t。   C、needn`t+have+过去分词,表示本来不必做而实际已经做的行为。   You needn`t have told them that。   You needn`t have bought that dictionary。I have a spare one。   2、must也有三种用法。   A、must表示命令、强制。否定式mustn`t,将来式have to,过去式had to。如;Cars mustn`t be parked in front of this house。 I had to leave at 6 yeserday。   B、 must表示主观意志和个人决心,意为“应当”、“应该”否定式needn`t,将来式will have to,过去式had to,dian`t need to, did not have to。如;   Must I clean all the rooms?No,you needn`t(或No,you don`t have to)。   C、must表示推测,判断“必定”“一定”;must be 现在;must have done过去。   You have worked hard all day;you must be tired。   I didn`t hear the phone,I must have been asleep。   注;have to与must的区别;同义,但msut表示说话人的主观意志,have to却表示客观需要。   3、should+have done 表示过去应该做而没有做。   Should`t have done表示“本不应该做某事,而实际却做了”的意思。如;   The plant is dead。I should have watered it。   She shouldn`t Have let the baby play with the scissors。   4不同的情态动词家动词不定式的完成式可以表示不同的意思;   (1may(might)+have+过去分词;用于肯定句和否定句,表示多已经发生的事情的不肯定的推测,相当于“可能,大概”,其中might较may语气更弱,把握更小。   She might have gone to see her dorctor last week,but I am not sure。   Don`t worry ,your husband may not have been burt seriously。   别急,你丈夫也许伤得不厉害。   (2)can(could)+have+过去分词;用于过去的时间,说明谋事可能或不可能已发生。如;   I simply can`t undersant how he could have made such a mistake。   This letter can`t have been written by her 。She is only five。   “could+have+过去分词”有时可表示过去可以做谋事,但却未做。如;   He walked there, but he could have taken a taxi。   “couldn`t+have+过去分词”有时表示无论如何也不可能做到。   I couldn`t have called you。 I wasn`t hear a telephone。   (3needn`t+have+过去分词;表示不必做的事情却做了,可译为“其实不必”   You needn`t have woken him up。It`s only five。

A. worked B. would workC. would be workingD. has been working 答案 A 解析: 考查一般过去时的基本用法。句中并列连词and连接两个发生在过去的顺承的动作,时态应该一致。 4. -- Your job ______ open for your return.-- Thanks. A. will be kept
B. will keep
C. had kept
D. had been kept 答案 A 解析: keep the job/the position open使、职位等处于空缺状态,由句意“随时欢迎你回来工作”可知用将来时。 5. -- ______ you ______ him around the museum yet? -- Yes. We had a great time there. A. H shownB. Do; show C. H shown D. D show 答案 A 解析: 此处表示说话者询问对方“有没有带领他参观博物馆”的结果,故用现在完成时。 6. -- I saw Jane and her boyfriend in the park at eight yesterday evening. -- Impossible. She ______ TV with me in my home then. A. watched
B. had watched
C. would watch D. was watching 答案 D 解析: 考查动词时态。句意为:“我昨晚8点钟在公园看见简和她男朋友了!”“不可能。她当时正在我家和我一起看电视。”此处时间状语为then,指的是at eight yesterday evening,指过去某一时间点正在进行的动作,故应用过去进行时态。 7. The flowers were so lovely that they ______ in no time. A. sold B. had been sold
C. were sold
D. would sell 答案 C 解析: 由“were so...”可知此处用一般过去时态;flowers应该是“被卖光”,故用被动形式。 8. -- What’s that noise? -- Oh, I forgot to tell you. The new machine ______. A. was testedB. will be testedC. is being testedD. has been tested 答案 C 解析: 根据一对一的问答可知,“机器正在被检测”,故选C项。 9. In a room above the store,where a party ______, some workers were busily setting the table.

You ______ in front of that computer too long. A. work
B. are workingC. have been working
D. worked 答案 C 解析: 考查动词的时态。由“I have got a headache”可知,空处应用现在完成进行时表示动作“从过去开始持续至今且还会进行下去”,体现过去开始的动作对现在的影响及结果。 二、热点时态: 一般过去时,现在完成时,过去完成时,过去进行时 1.
