3. 高一英語比較重要的語法有哪些
先行詞在定語從句中充當主語，賓語，時間，地點，原因狀語。結構：先行詞+關系詞+定語從句。1. There she saw a wall of water that was quickly advancing towards her.2. 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)定語從句分為限定性定語從句和非限定性定語從句：限定性定語從句：從句對先行詞進行必要的描述或說明，缺少它，則句義顯得不完整，從句與先行詞緊密相連。非限定性定語從句：對先行詞進行補充說明，解釋，它與先行詞之間有逗號隔開。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)關系詞前面可以根據定語從句的內容加上一些介詞，這些關系詞在介詞後面常用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.知識重點與難點(一)當先行詞有最高級，序數詞修飾，是不定代詞，或是all, no, only等形式時，關系代詞一般用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)當先行詞是表示時間，地點，原因的詞時，關系詞用when, where, why 還有which, that1. I』m very glad to return to my hometown where I had lived for 10 years.2. This is my hometown which I used to talk about to you.3. 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)定語從句的簡化表達：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.說明：以上的定語從句部分可以用更加簡單的非謂語形式表達出來：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.說明：修飾一個名詞除了後面用定語從句以外，還可以用非謂語動詞形式：doing短語，done短語，being done短語，to be done短語修飾。其結構和意思如下：1. 被修飾名詞+doing短語： 正在做….的人/正在發生的事。2. 被修飾名詞+ done短語： 被…..的人/事3. 被修飾名詞+being done短語：正在被…..的人/事4. 被修飾名詞+ to be done短語：將要被…..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.總結：以上做定語的那些短語就是英語語法中所說的分詞，不定式的各種形式作定語。1. 這些短語作定語應放在被修飾名詞的後面。如果單獨一個V-ing或V-ed形式作定語，則可以放在被修飾名詞前面。2. 分詞作定語時，其動作應與全句動作同時發生。V-ing表示主動意義和正在做，V-ed表示被動意義。being done表示正在被做的3. 不定式作定語表示將要發生的，to be done表示將要被做的【典型例題】[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為非限定性定語從句修飾先行詞Friendship用which連接定語從句。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作為定語從句修飾先行詞Uncle Li，從句完整的表達是：I worked with Uncle Li three years ago. 所以關系詞前應加上介詞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：定語從句_____ at the meeting for his carelessness in his work修飾先行詞the reason指「他在會上就他工作中的粗心解釋的原因。先行詞在從句中做賓語。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：非限定性定語從句_____ work is rather hard修飾先行詞teachers, 它與從句中的work是從屬關系，關系詞用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年被首次舉行的奧運會，直到1912年才容納女運動員。_____in 776 BC做定語修飾The Olympic Games，指過去的內容，表示被動。用done做定語。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：根據句意房子即將開工。_____ for the teachers and the construction work修飾The houses應為The houses The houses將要為教師和施工修建的房子。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：根據句意：比如說，我們當中參加一個對我們毫不重要的會議的人會有多少人對這個討論感興趣呢?_____, say, a meeting that is not important to us修飾How many of us做定語。與全句動作同步.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：非限定性定語從句__ is working in Australia修飾先行詞three children，根據從句中的is判斷，是說：三個孩子中的一個在澳大利亞工作。答案：B【模擬試題】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)對過去的事實進行推測：結構：情態動詞+have done / been+名詞/形容詞/介詞短語例句：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 ?情態動詞表達虛擬語氣：表達「本來…」，「不然早就…」。這是情態動詞的一種虛擬語氣用法。表示說話人所講的與所發生的事實相反。表達了說話人的埋怨，後悔的語氣。其結構是在一些情態動詞後面加 have done 結構。根據要表達的意思，有如下結構：should have done / ought to have done：本應該……shouldn』t have done / oughtn』t to have done：本不該……could have done：本來可以……needn』t have done：本來沒必要……would like to have done：本來很想……would rather not have done: 本來不願意……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.知識難點：某些情態動詞的特殊用法：need 和dare 的兩種形式的用法need 和dare可以用做實義動詞，後面接不定式(to do)結構，在疑問句和否定句中，加助動詞do/does/did/或don』t/doesn』t/didn』t。作為情態動詞使用時，主要用於疑問句和否定句中。情態動詞needn』t(沒有必要，不必)相當於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+從句。 意思是：我肯定…… = I』m sure或There is no doubt that+從句。例句：I dare say that my uncle will get the money if I die.will和would表示「意志」或「願意」，would 則指過去願意做……例句：1. He said that he would help us.2. You may telephone if you will accept this job.would可以表達「過去習慣做……」類似於「used to do」例句：1. When we were children, we would go swimming every summer in that river.表示請求，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. 用於第一，三人稱，表示「請求」;「建議」 或「推薦」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. 用於第二人稱，表示「命令，「要求」，「許諾」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.在表示推測的否定句或疑問句中，常用can /can』t /could / couldn』t表示，意思是：「可能…嗎?」;「…不可能…」。而不能使用mustn』t或must等詞。【典型例題】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：本題考查情態動詞推測性用法。 根據he is the last one to help others.(他是最不可能幫助別人的人)，既然如此，那麼「幫助你」的可能性也就最小了。答案為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：根據備選答案。 can表示推測時用於疑問句或否定句中。本題首句就應該是Guess who can it be? 第二句應該是I think it must be Tom.(說話人十分肯定)。第三句表達了說話人對前一個人的否定。即：I don』t think it can be him/he.(不可能是他)。答案為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：關鍵詞Sure告訴我們說話人的口氣十分肯定。根據句子語境：她此刻肯定正在校園散步呢。must be doing表示肯定正在做。答案為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：首句說：我在紐約住在一家賓館里。在此a hotel是泛指。所以D選項不合題意。

動詞的語氣——虛擬語氣(The Subjunctive Mood)
一、語氣的定義和種類
l、語氣：語氣是動詞的一種形式，它表示說話人對某一行為或事情的看法和態度。
2、語氣的種類：
(1)陳述語氣: 表示動作或狀態是現實的、確定的或符合事實的，用於陳述句、疑問句和某些感嘆句。如：We are not ready. 我們沒准備好。What a fine day it is!多好的天氣啊!
(2)祈使語氣: 表示說話人的建議、請求、邀請、命令等。如: Open the door, please。請打開門。
(3)虛擬語氣: 表示動作或狀態不是客觀存在的事實，而是說話人的主觀願望、假設或推測等。如: If I were you, I should study English. 如果我是你，我就學英語了。May you succeed! 祝您成功！
二、虛擬語氣在條件從句中的用法
條件句有兩類，一類是真實條件句，一類是虛擬條件句。如果假設的情況是有可能發生的，就是真實條件句。在這種真實條件句中的謂語用陳述語氣。如: If it doesn』t rain tomorrow, we will go to the park. 如果明天不下雨，我們就去公園。
如果假設的情況是過去或現在都不存在的，或將來不大可能發生的，則是虛擬條件句。如: If he had seen you yesterday, he would have asked you about it. 如果他昨天見到你，他會問你這件事的。(事實上他昨天沒見到你，因此也未能問你這件事。)
在含有虛擬條件句的復合句中，主句和從句的謂語都要用虛擬語氣。現將虛擬條件從句和主句的動詞形式列表如下:
與現在事實相反: 從句: 動詞的過去式（be的過去式一般用were）
主句:would/ should/ could/ might + 動詞原形
與過去事實相反 : 從句 :had + 過去分詞
主句 :would/ should/ could/ might + have + 過去分詞
與將來事實相反 : 從句:動詞過去式，should + 動詞原形，
主句 :were to + 動詞原形 would/ should/ could/ might + 動詞原形
注: 主句中的should只用於I、we，但在美國英語中，should常被would代替；從句中的should可用於各種人稱。
l、表示與現在事實相反的假設和結果。如: If my brother were here, everything would be all right. 要是我哥哥在這兒 ，一切都沒問題了。
2、表示與過去事實相反的假設和結果。如: If you had taken my advice，you wouldn't (couldn』t) have failed in the exam. 如果你按照我的建議去做，你一定不會(不可能)考試不及格。
3、表示與將來事實可能相反的假設和結果。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，他們將不出去了。
4、有時條件從句中的動作和主句中的動作發生的時間不一致（表示錯綜時間的虛擬語氣），這時動詞的形式要根據它所表示的時間加以調整。例如: If you had listened to the doctor, you would be all right now. 如果你當初聽了醫生的話，身體現在就好了。(從句動作指過去，主句動作指現在)
5、虛擬條件句可以轉換成下列形式:
(l)省略連詞if。在書面語中，如果虛擬條件從句中有were，had 或 should，可以把if省略，把這幾個詞放到主語之前，構成主謂倒裝。例如: Should he come (If he should come), tell him to ring me up. 他要是來了，讓他給我打個電話。Were I you (If I were you), I would not do it. 我要是你，就不做這事。
(2)用介詞短語代替條件狀語從句。有時假設的情況並不用條件從句表示出來，而是通過介詞短語來表示。如: Without air (If there were not air), there would be no living things. 如果沒有空氣的話，就不會有生物了。But for your help (If it hadn』t been for your help) I couldn』t have done it. 要是沒有你的幫助，我就不可能完成這件事。
假設的情況有時可以通過上下文或其他方式表現出來。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，否則，我就和他們一起去那兒了。(如果我那天不忙的話，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.) 我本來該完成這項工作的，但我生病了。(如果我沒生病的話，我就會完成……)
6、省去條件從句或主句：表示虛擬語氣的主句或從句有時可以省略，但其含義仍可以推知。
(1)省去條件從句。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")(事實是:你自己沒洗衣服，因為你不想洗。)
(2)省去主句(常用以表示願望)。如: If my grandmother were with me! 如果我的祖母與我在一起多好啊!(事實是:祖母已不在世。)；If only she had not left! 如果她沒走就好了!(事實是:她已經走了。)
三、虛擬語氣的其他用法
l、虛擬語氣在主語從句中的用法：在"It is important (strange，natural，necessary)that…"這類句型里，that所引導的主語從句中的謂語動詞常用 「should+動詞原形」結構，表示某事是"重要"、"奇怪"、"自然"、"必要"等意義。如: It is important that every member (should) inform himself of these rules. 重要的是每個成員知道這些規則。
2、虛擬語氣在賓語從句中用法：
(1)在動詞wish後的賓語從句中，表示與現在或過去的事實相反，或對將來的主觀願望，從句通常省略連詞that。1)表示對現在情況的虛擬:從句動詞用過去式或過去進行式(be動詞一般用were)。如: I wish I knew the answer to the question. 我希望知道這個問題的答案。(可惜不知道)；2）表示對過去情況的虛擬:從句動詞常用"had+過去分詞"。如: I wish (wished) I hadn』t spent so much money. 我後悔不該花那麼多錢。(實際上已經花掉)；3)表示對將來的主觀願望:謂語動詞形式為"would+動詞原形"。此時要注意，主句的主語與從句的主語不能相同，因為主句的主語所期望的從句動作能否實現，取決於從句主語的態度或意願(非動物名詞除外)。如: I wish it would stop raining. 但願雨能停止；I wish you would come soon. 但願你立刻來。
(2)在suggest，demand，order，propose，insist，command，request，desire等動詞後的賓語從句中，謂語動詞用「should + 動詞原形」，表示建議、要求、命令等。如: I demand that he (should) answer me immediately. 我要求他立刻答復我。
3、虛擬語氣在狀語從句中的用法
(1)在帶有even if/ even though引導的讓步狀語從句的主從復合句中，主句和從句都用虛擬語氣，動詞形式與含有非真實條件句的虛擬語氣相同。如: Even if he had been ill, he would have gone to his office. 即使生了病，他都去辦公室。
(2)由as if或as though引導的狀語從句表示比較或方式時。從句謂語形式為動詞的過去式(be用were)或 「had+過去分詞」。如: He treated me as if I were a stranger. 他那樣對待我，好像我是陌
生人似的。She talked about the film as if she had really seen it. 她談論那部影片，就好像她確實看過一樣。
注:如果表示的事情可能會發生，那麼方式狀語從句中的謂語動詞可用陳述語氣。
(3)在in order that或so that引導的目的狀語從句中，謂語動詞多用 「could或might（有時也用should）+ 動詞原形」。如: Mr green spoke slowly so that his students could (might) hear clearly. 格林先生說得很慢，好讓學生聽清楚。
4、虛擬語氣在定語從句中的用法：在"It is time (that) …"句型中，定語從句的謂語動詞常用虛擬語氣表示將來，動詞形式一般用過去式，意思是"該干某事的時候了"。如: It』s (high) time we did our homework. 我們該做作業了。
5、虛擬語氣在簡單句中的用法
(1)情態動詞的過去式用於現在時態時，表示說話人的謙虛、客氣、有禮貌，或委婉的語氣，常見於日常會話中。如: It would be better for you not to stay up too late. 你最好別太晚睡覺。
(2)在一些習慣表達中。如: I would rather not tell you. 我寧願不告訴你。
(3)用「may + 動詞原形」表示"祝願"、"但願」，此時may須置於句首（多用於正式文體中）。如：May you be happy!祝你快樂！May good luck be yours.祝你順利。
