4) 现在时刻的状态、能力、性格、个性。例如:

第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。

In Japan, someone who sees another person making the gesture will think it means money.3. A theme park is a collection of rides, exhibitions or other attractions that are based on a common theme.4. The park has a conservation center that helps protect marine animals and their habitats in the rivers and coastal waters of Asia.5. Visitors can go on exciting rides where they can feel what it is like to do the things they have seen their heroes do in the movie.6. Oprah Winfrey is a black woman whose rise to fame is an inspiring story.(二)定语从句分为限定性定语从句和非限定性定语从句:限定性定语从句:从句对先行词进行必要的描述或说明,缺少它,则句义显得不完整,从句与先行词紧密相连。非限定性定语从句:对先行词进行补充说明,解释,它与先行词之间有逗号隔开。1. Before she could move, she heard a loud noise, which grew to a terrible roar.2. Tree after tree went down, cut down by the water, which must have been three meters deep.3. Flora, whose beautiful hair and dress were all cold and wet, started crying.4. Their talk includes rhythm and rhyming words as well as tongue twisters, which often make the audience applaud.(三)关系词前面可以根据定语从句的内容加上一些介词,这些关系词在介词后面常用which 或whom.1. There was a man with whom I would have to work together and finally the manager of the company.2. Many people who saw the film were afraid to swim in the sea when they remembered the scenes in which people were eaten by the shark.知识重点与难点(一)当先行词有最高级,序数词修饰,是不定代词,或是all, no, only等形式时,关系代词一般用that,而不能用which。1. The Titanic was the largest ship that had ever been built at that time.2. There is one thing that keeps worrying me.(二)当先行词是表示时间,地点,原因的词时,关系词用when, where, why 还有which, that1.

I think I can understand the reason why he didn’t tell the truth to me.4. No one believes the reason that he gave us about his absence at the meeting.(三)定语从句的简化表达:1. The man who is sitting on the platform is a professor from Wuhan University.2. The letter that was mailed last night will reach him tomorrow.3. The question that is being discussed is very important.4. You are welcome to a party to be given in our class at 7:45.说明:以上的定语从句部分可以用更加简单的非谓语形式表达出来:1. The man sitting on the platform is a professor from Wuhan University.2. The letter mailed last night will reach him tomorrow.3. The question being discussed is very important.4. You are welcome to a party to be given in our class at 7:45.说明:修饰一个名词除了后面用定语从句以外,还可以用非谓语动词形式:doing短语,done短语,being done短语,to be done短语修饰。其结构和意思如下:1. 被修饰名词+doing短语: 正在做….的人/正在发生的事。2. 被修饰名词+ done短语: 被…..的人/事3. 被修饰名词+being done短语:正在被…..的人/事4. 被修饰名词+ to be done短语:将要被…..的人/事(1)Do you know the man talking to my sister ?(2)The “crazy” gesture, moving the index finger in a circle in front of the ear, means “you have a phone call” in Brazil.(3)Did you see that car being repaired ?(4)In a camera, the lens must be focused on the object to be photographed.(5)The students to attend the meeting will arrive here tomorrow.(6)Goods imported from abroad are not always better than those made in China.(7)The Yellow River, said to be “the mother river” runs across China like a huge dragon.总结:以上做定语的那些短语就是英语语法中所说的分词,不定式的各种形式作定语。1. 这些短语作定语应放在被修饰名词的后面。如果单独一个V-ing或V-ed形式作定语,则可以放在被修饰名词前面。2. 分词作定语时,其动作应与全句动作同时发生。V-ing表示主动意义和正在做,V-ed表示被动意义。being done表示正在被做的3. 不定式作定语表示将要发生的,to be done表示将要被做的【典型例题】[例1] Friendship is needed by all, _____ plays an important role in people’s lives.A. whichB. thatC. whoD. it分析:_____ plays an important role in people’s lives为非限定性定语从句修饰先行词Friendship用which连接定语从句。答案:A[例2] Uncle Li _____ I worked three years ago has retired now.A. whoB. whom C. with whomD. to whom分析:_____ I worked three years ago作为定语从句修饰先行词Uncle Li,从句完整的表达是:I worked with Uncle Li three years ago. 所以关系词前应加上介词with。答案:C[例3] Is this the reason _____ at the meeting for his carelessness in his work ?A. he explained B. what he explained C. how he explainedD. why he explained分析:定语从句_____ at the meeting for his carelessness in his work修饰先行词the reason指“他在会上就他工作中的粗心解释的原因。先行词在从句中做宾语。答案:A[例4] Teachers, _____ work is rather hard, are being better paid than before.A. who B. that C. whichD. whose分析:非限定性定语从句_____ work is rather hard修饰先行词teachers, 它与从句中的work是从属关系,关系词用whose答案:D[例5 ] The Olympic Games , _____ in 776 BC, didn’t included women players until 1912.A. first playingB. to be first playedC. first playedD. to be first playing分析:公元前776年被首次举行的奥运会,直到1912年才容纳女运动员。_____in 776 BC做定语修饰The Olympic Games,指过去的内容,表示被动。用done做定语。答案:C[例6] The houses _____ for the teachers and the construction work will start soon.A. built B. to be built C. to buildD. being built分析:根据句意房子即将开工。_____ for the teachers and the construction work修饰The houses应为The houses The houses将要为教师和施工修建的房子。答案:B[例7] How many of us_____, a meeting that is not important to us would be interested in the discussion?A. attendedB. attendingC. to attendD. have attended分析:根据句意:比如说,我们当中参加一个对我们毫不重要的会议的人会有多少人对这个讨论感兴趣呢?_____, say, a meeting that is not important to us修饰How many of us做定语。与全句动作同步.答案:B[例8] She has three children, _____ is working in Australia.A. whoB. one of whom C. one of them D. none of them分析:非限定性定语从句__ is working in Australia修饰先行词three children,根据从句中的is判断,是说:三个孩子中的一个在澳大利亚工作。答案:B【模拟试题】1.

You must be Jeanne. I’m Mathilde Loisel. We used to know each other very well.2. They must be in bed already at this time of the night.3. The teacher must be joking.4. Freda isn’t in class. She must be sick.5. There must be something wrong.6. She might be very clever, but she hasn’t got much common sense.7. He may be arriving this evening.8. He may be traveling around the world.9. The keys can’t be in the room. I have just searched it very carefully.10. Can the news be true ?(三)对过去的事实进行推测:结构:情态动词+have done / been+名词/形容词/介词短语例句:1. Mrs. Longmans must have been a pretty girl in her youth.2. He couldn’t have seen Anna yesterday. She’s gone abroad.3. I think I must have left my glasses in the library.4. He might have overslept again.5. Where can Tom have gone ?情态动词表达虚拟语气:表达“本来…”,“不然早就…”。这是情态动词的一种虚拟语气用法。表示说话人所讲的与所发生的事实相反。表达了说话人的埋怨,后悔的语气。其结构是在一些情态动词后面加 have done 结构。根据要表达的意思,有如下结构:should have done / ought to have done:本应该……shouldn’t have done / oughtn’t to have done:本不该……could have done:本来可以……needn’t have done:本来没必要……would like to have done:本来很想……would rather not have done: 本来不愿意……could / might / have done: 不然早就……例句:1. You shouldn’t have laughed at his mistakes.2. You could have told us earlier.3. I ought to have bought that dictionary last week.4. You ought not to have spent so much time in reading novels.5. We need not have been in a tearing hurry to catch the train.6. They would like to have seen that film last film.7. If he had given me his number, I could have telephoned him.8. They might have been frozen to death but for the rescue in time.知识难点:某些情态动词的特殊用法:need 和dare 的两种形式的用法need 和dare可以用做实义动词,后面接不定式(to do)结构,在疑问句和否定句中,加助动词do/does/did/或don’t/doesn’t/didn’t。作为情态动词使用时,主要用于疑问句和否定句中。情态动词needn’t(没有必要,不必)相当于don’t have to例句:1. It is cold, you need to wear some warm clothes.2. Need I stay here with you for a while ? Thank you, you needn’t.3. How dare you speak to parents like that ?注意:句型I dare say+从句。 意思是:我肯定…… = I’m sure或There is no doubt that+从句。例句:I dare say that my uncle will get the money if I die.will和would表示“意志”或“愿意”,would 则指过去愿意做……例句:1. He said that he would help us.2. You may telephone if you will accept this job.would可以表达“过去习惯做……”类似于“used to do”例句:1. When we were children, we would go swimming every summer in that river.表示请求,固定的句型:Will/Would you please do…? / Would you like to do…?例句:Will/Would you please give him a message when you see him ?shall1. 用于第一,三人称,表示“请求”;“建议” 或“推荐”例句:1. Shall we start the meeting now?2. Shall I watch TV now ?3. Shall my son carry the case for you ?2. 用于第二人称,表示“命令,“要求”,“许诺”例句:1. You shall take whatever you like.2. You shall not go to the party with me if you make so much noise again.在表示推测的否定句或疑问句中,常用can /can’t /could / couldn’t表示,意思是:“可能…吗?”;“…不可能…”。而不能使用mustn’t或must等词。【典型例题】1. —Do you think he will do me a favor ?—As far as I know, he is the last one to help others. He _____ be prepared to give you a hand, though.A. mightB. must C. canD. should分析:本题考查情态动词推测性用法。 根据he is the last one to help others.(他是最不可能帮助别人的人),既然如此,那么“帮助你”的可能性也就最小了。答案为A2. —Look, someone is coming. Guess who it ____ be ?—I think it ___ be Tom.—I don’t think it ___ be ____ .A. can ; must ; can ; heB. may ; can ; must ; himC. must ; can ; must ; hisD. might ; must ; can ; himself分析:根据备选答案。 can表示推测时用于疑问句或否定句中。本题首句就应该是Guess who can it be? 第二句应该是I think it must be Tom.(说话人十分肯定)。第三句表达了说话人对前一个人的否定。即:I don’t think it can be him/he.(不可能是他)。答案为A3. —Do you know Ms. Wang likes walking after supper ?—Sure. She ____ around the campus now.A. must be walkingB. must walkC. may walkD. may be walking分析:关键词Sure告诉我们说话人的口气十分肯定。根据句子语境:她此刻肯定正在校园散步呢。must be doing表示肯定正在做。答案为A4. —I stayed at a hotel in New York.—Oh, did you ? You _____ with Barbara.A. could have stayed B. could stay C. would sayD. must have stayed分析:首句说:我在纽约住在一家宾馆里。在此a hotel是泛指。所以D选项不合题意。

动词的语气——虚拟语气(The Subjunctive Mood)
一、语气的定义和种类
l、语气:语气是动词的一种形式,它表示说话人对某一行为或事情的看法和态度。
2、语气的种类:
(1)陈述语气: 表示动作或状态是现实的、确定的或符合事实的,用于陈述句、疑问句和某些感叹句。如:We are not ready. 我们没准备好。What a fine day it is!多好的天气啊!
(2)祈使语气: 表示说话人的建议、请求、邀请、命令等。如: Open the door, please。请打开门。
(3)虚拟语气: 表示动作或状态不是客观存在的事实,而是说话人的主观愿望、假设或推测等。如: If I were you, I should study English. 如果我是你,我就学英语了。May you succeed! 祝您成功!
二、虚拟语气在条件从句中的用法
条件句有两类,一类是真实条件句,一类是虚拟条件句。如果假设的情况是有可能发生的,就是真实条件句。在这种真实条件句中的谓语用陈述语气。如: If it doesn’t rain tomorrow, we will go to the park. 如果明天不下雨,我们就去公园。
如果假设的情况是过去或现在都不存在的,或将来不大可能发生的,则是虚拟条件句。如: If he had seen you yesterday, he would have asked you about it. 如果他昨天见到你,他会问你这件事的。(事实上他昨天没见到你,因此也未能问你这件事。)
在含有虚拟条件句的复合句中,主句和从句的谓语都要用虚拟语气。现将虚拟条件从句和主句的动词形式列表如下:
与现在事实相反: 从句: 动词的过去式(be的过去式一般用were)
主句:would/ should/ could/ might + 动词原形
与过去事实相反 : 从句 :had + 过去分词
主句 :would/ should/ could/ might + have + 过去分词
与将来事实相反 : 从句:动词过去式,should + 动词原形,
主句 :were to + 动词原形 would/ should/ could/ might + 动词原形
注: 主句中的should只用于I、we,但在美国英语中,should常被would代替;从句中的should可用于各种人称。
l、表示与现在事实相反的假设和结果。如: If my brother were here, everything would be all right. 要是我哥哥在这儿 ,一切都没问题了。
2、表示与过去事实相反的假设和结果。如: If you had taken my advice,you wouldn't (couldn’t) have failed in the exam. 如果你按照我的建议去做,你一定不会(不可能)考试不及格。
3、表示与将来事实可能相反的假设和结果。如: If it were Sunday tomorrow, I should (would,could,might) go to see my grandmother. 如果明天是星期天,我就 (可能)去看望我奶 奶。If it were to snow this evening, they would not go out. 如果今晚下雪,他们将不出去了。
4、有时条件从句中的动作和主句中的动作发生的时间不一致(表示错综时间的虚拟语气),这时动词的形式要根据它所表示的时间加以调整。例如: If you had listened to the doctor, you would be all right now. 如果你当初听了医生的话,身体现在就好了。(从句动作指过去,主句动作指现在)
5、虚拟条件句可以转换成下列形式:
(l)省略连词if。在书面语中,如果虚拟条件从句中有were,had 或 should,可以把if省略,把这几个词放到主语之前,构成主谓倒装。例如: Should he come (If he should come), tell him to ring me up. 他要是来了,让他给我打个电话。Were I you (If I were you), I would not do it. 我要是你,就不做这事。
(2)用介词短语代替条件状语从句。有时假设的情况并不用条件从句表示出来,而是通过介词短语来表示。如: Without air (If there were not air), there would be no living things. 如果没有空气的话,就不会有生物了。But for your help (If it hadn’t been for your help) I couldn’t have done it. 要是没有你的帮助,我就不可能完成这件事。
假设的情况有时可以通过上下文或其他方式表现出来。如: I was busy that day. Otherwise I would have gone there with them. (If I hadn’t been busy that day, I would have gone there with them.) 我那天很忙,否则,我就和他们一起去那儿了。(如果我那天不忙的话,我就……);I would have finished the work, but I have been ill. (If I hadn’t been ill, I would have finished the work.) 我本来该完成这项工作的,但我生病了。(如果我没生病的话,我就会完成……)
6、省去条件从句或主句:表示虚拟语气的主句或从句有时可以省略,但其含义仍可以推知。
(1)省去条件从句。如: You could have washed your clothes yourself. 你本可以自已洗衣服的。省去了"If you had wanted to")(事实是:你自己没洗衣服,因为你不想洗。)
(2)省去主句(常用以表示愿望)。如: If my grandmother were with me! 如果我的祖母与我在一起多好啊!(事实是:祖母已不在世。);If only she had not left! 如果她没走就好了!(事实是:她已经走了。)
三、虚拟语气的其他用法
l、虚拟语气在主语从句中的用法:在"It is important (strange,natural,necessary)that…"这类句型里,that所引导的主语从句中的谓语动词常用 “should+动词原形”结构,表示某事是"重要"、"奇怪"、"自然"、"必要"等意义。如: It is important that every member (should) inform himself of these rules. 重要的是每个成员知道这些规则。
2、虚拟语气在宾语从句中用法:
(1)在动词wish后的宾语从句中,表示与现在或过去的事实相反,或对将来的主观愿望,从句通常省略连词that。1)表示对现在情况的虚拟:从句动词用过去式或过去进行式(be动词一般用were)。如: I wish I knew the answer to the question. 我希望知道这个问题的答案。(可惜不知道);2)表示对过去情况的虚拟:从句动词常用"had+过去分词"。如: I wish (wished) I hadn’t spent so much money. 我后悔不该花那么多钱。(实际上已经花掉);3)表示对将来的主观愿望:谓语动词形式为"would+动词原形"。此时要注意,主句的主语与从句的主语不能相同,因为主句的主语所期望的从句动作能否实现,取决于从句主语的态度或意愿(非动物名词除外)。如: I wish it would stop raining. 但愿雨能停止;I wish you would come soon. 但愿你立刻来。
(2)在suggest,demand,order,propose,insist,command,request,desire等动词后的宾语从句中,谓语动词用“should + 动词原形”,表示建议、要求、命令等。如: I demand that he (should) answer me immediately. 我要求他立刻答复我。
3、虚拟语气在状语从句中的用法
(1)在带有even if/ even though引导的让步状语从句的主从复合句中,主句和从句都用虚拟语气,动词形式与含有非真实条件句的虚拟语气相同。如: Even if he had been ill, he would have gone to his office. 即使生了病,他都去办公室。
(2)由as if或as though引导的状语从句表示比较或方式时。从句谓语形式为动词的过去式(be用were)或 “had+过去分词”。如: He treated me as if I were a stranger. 他那样对待我,好像我是陌
生人似的。She talked about the film as if she had really seen it. 她谈论那部影片,就好像她确实看过一样。
注:如果表示的事情可能会发生,那么方式状语从句中的谓语动词可用陈述语气。
(3)在in order that或so that引导的目的状语从句中,谓语动词多用 “could或might(有时也用should)+ 动词原形”。如: Mr green spoke slowly so that his students could (might) hear clearly. 格林先生说得很慢,好让学生听清楚。
4、虚拟语气在定语从句中的用法:在"It is time (that) …"句型中,定语从句的谓语动词常用虚拟语气表示将来,动词形式一般用过去式,意思是"该干某事的时候了"。如: It’s (high) time we did our homework. 我们该做作业了。
5、虚拟语气在简单句中的用法
(1)情态动词的过去式用于现在时态时,表示说话人的谦虚、客气、有礼貌,或委婉的语气,常见于日常会话中。如: It would be better for you not to stay up too late. 你最好别太晚睡觉。
(2)在一些习惯表达中。如: I would rather not tell you. 我宁愿不告诉你。
(3)用“may + 动词原形”表示"祝愿"、"但愿”,此时may须置于句首(多用于正式文体中)。如:May you be happy!祝你快乐!May good luck be yours.祝你顺利。
