& 前面我们讲了什么是名词性从句、定语从句和状语从句及其各自的作用，三种从句都涉及到关联词的用法，下面我们反过来，从关联词用法的角度，即如何选用关联词-----做题的角度来归纳一下重点关联词的用法。 一、as 的用法 1. As 连词：引导时间、原因、让步、比较、方式状语从句 As time went on, he grew more and more impatient.(时间状语从句) As he is not well, I’ll go myself. (原因状语从句) Like the book as he does, he won’t buy it. (让步状语从句) Your camera is as expensive as hers. (比较状语从句) Do as the Romans do when you are in Roman. (方式状语从句) 2. As 关系代词 ：引导定语从句,在从句中做主语和宾语。 I have the same book as you bought just now. 比较：this is the same book that I used yesterday. She is such a good student as we all like. = She is so good a student as we all like. 二、what的用法 引导名词性从句（主语、宾语、表语从句等），在从句中做主语、宾语、表语、定语。（what不能引导定语从句和状语从句） What could be done has been done. At last, they reached what they thought was the place they had been dreaming for. After what seemed like hours, he came out with a bitter smile. I don’t know what book the children can read. 比较：-- Here are five books, which one do you want? -- I don’t know which one I want. I have no idea what he did.（同位语从句） as,what 用法练习 1. I’m at least _____ age _____Robert if I’m not older than he. A. as B. with C. as same as D. as 2 .______, I have never seen anyone who’s as capable as John. A． Much as I have traveled B. As I have traveled C. As much I have traveled D. As I much have traveled 3. Jinan is no longer the same city _______it used to be. A．as B. what C. that D. which 4. Jinan is no longer _______it used to be. A．as B. what C. that D. which 5. This problem was of _____ importance ____ we could not afford to take no notice of. A． that B. that C. so D. as 6. Mr. Smith has not yet answered my question ____ I can go with him. A. that B. that C. whether D. whether 7. The patient looks much better .______is it that has made him _____he is today? A．W that B. W what C. that D. which 8. There are ten pens here, ______ one do you want? A．which B. what C. whose D. that 9. Zhang Ziyi is a famous actress, _______I should also like to be. A．what B. who C. which D. that 10. This photo of mine was taken ______ stood the famous Eastern Bright Pearl in Shanghai. A．what B. which C. where D. the place where 三、 since = now (that）的用法 1、 “既然”，多用来表示已知或稍加分析即可表明的原因。多用于句首。 Since everyone is here, let’s begin our meeting. 2、“自从…以来”，引导时间状语从句，表示延续到现在的动作。从句谓语 一般用一般过去时，主句谓语常用现在完成时。 I have been looking forward to seeing you again since I last saw you. Since the first case was discovered in 1981, nearly 24 million people have died of AIDS. 常用句型：It is / has been / seems + 一段时间 + since…… It seems a long time since I met you last. It is / has been two years since I returned from America． 特别提醒: 当从句谓语是短暂性动词时，通常译为“从……起已经（多长时 间了）” 当从句谓语是延续性动词时，则表示该动作“终止已经（多长时 间了）” It’s been years since I enjoyed myself so much. 我已经许多年没有这样痛快了。 It is three years since he joined the army. 他参军已经三年了。 四、 until / till的用法 1、 用在肯定句中，“直到…为止”，表示某一个动作一直持续到until/till…… 所表示的时间为止。此时，主句谓语必须是延续性动词。 He waited until/till I returned. 2、用在否定句中，“直到……才”,表示某一动作直到until…所表示的时间才 发生。此时，主句谓语必须是短暂性动词。 As a matter of fact, I did not begin work until he had gone. Don’t get off the bus until it has stopped. 特别提醒: ① 在until/till从句中，往往用一般现在时和现在完成时表示将来。无论是用在肯定句中，还是用在否定句中，不可以使用将来时。 ② 在倒装句型和强调句型中只能用until。 Not until we know more will we be able to improve the situation. It was not until she took off her glasses that I realized she was a famous film star. 五、before的用法 1、before在引导时间状语从句时的基本意思是“在……之前”。有时before 引导的从之前，可以有自己的状语。 The day before he left home, he gave the whole house a thorough cleaning. 2、 before重点句型： It was not long before… （过去）没过多久就…… It was long before… 过了很久才…… It will not be long before… 要不了多久就…… It will be long before… 要过很久才…… 特别提醒: long这个抽象的时间也可改为years, weeks, two years, two weeks 等具体表时间的词。 It was about a year before he married Fang. It will be several months before everything returns to normal. It was not long before he returned to Beijing. It seemed seconds before he woke up. 似乎才过了几秒钟他就醒了。 3、before 的汉译 before的译法非常灵活，应结合具体情况机动处理。常见的意思有：…… （肯定句）；……就（否定句）；还未来得及；趁……；不知不觉…… I hadn’t waited long before he came. 我没等多久，他就来了。 After that it still took seven years before they finally got married. 他们又过了7年才结婚。 You should do it before it is too late. 趁现在还不算太晚，你应该赶快做。 He hung up before I could answer the phone. 我还没来得及接电话，他就挂了。 The summer holiday came to an end before I knew it. 不知不觉暑假就过去了。 since = now (that），until / till，before的用法练习 1. ---How long do you think it will be _____ China sends a manned spaceship to the moon? ---Perhaps two or three years. A. when B. until C. that D. before 2. Not until the game had begun _____ at the sports ground. A．had he arrived B. would he have arrived C. did he arrive D. should he have arrived 3. Problems relating to people’s livelihood（民生）have been the focus of the government, especially _____ Premier Wen Jiabao included them in his government work report last year. A．when B. if C. since D. until 4. ---Why didn’t you try your best to stop him from doing so? ---I tried to , but _____ I could, the policemen turned up. A．until B. when C. while D. after 5. Our English teacher has ways to hold our attention _____ he reaches the end of his lesson. A．when B. unless C. after D. until 6.

A．he went B. did he go C. had he gone D. he had gone 10. Scientists say it may be five or six years _____ it is possible to test this medicine on human patients. A．since B. after C. before D. when 六、that的用法 1、用作关系代词,引导限制性定语从句,可以指人或物,可以代替who, whom, which. This is the best article that has been written on the subject. The letter (that/which) I received yesterday was from my brother. 2、 用作连词,在谓语动词、介词、动词不定式、分词、动名词之后引导宾语从句, 常常可以省略.在某些形容词(如sure, clear, certain等)之后,也可以由that 引导宾语从句.如: They said (that) they could do it ahead of schedule. We are glad that so many old friends will attend our tea party. 注意：1）当and 连接两个或更多的宾语从句时,that 往往不可以省略.如: He told me that he had finished his homework and that he would go to the cinema tonight. 2）当宾语从句比较长时,往往可以用it 作形式宾语.如: We make it clear that he is very honest. 3、用作连词,引导主语从句、表语从句、同位语从句,在句中不作任何成分,只起连接作用但一般不能省略.如: That he did it himself made us very happy. The trouble is that you couldn’t come. I had no idea that he had gone abroad. 注意：当主语从句比较长时,往往可以用it 代替它作形式主语,而将真正的主语从句置后,以达到平衡句子的目的.如: It’s a pity that you didn’t attend the interesting party. 4、在in order that...,so that ...，so...that, such...that中引导目的、结果状语从句。如: He raised his voice in order that all students in the hall could hear him clearly. It’s such a fine day that we all go swimming. ＝It’s so fine a day that we all go swimming. 5、用于强调结构中,构成强调句型.如: It was after talking for half an hour that the old man mentioned the name of Kunta Kinte. It was my ancestor that I decided to find out about. 七、which的用法 用作关系代词，引导限制性和非限制性定语从句 She received an invitation from her boss, which came as a surprise. The tool with which he is working is called a hammer. which引导定语从句时与as的区别 1)as所引导的从句既可以放在句首，也可放在句末，而which所引导的从句只可以放在句末。 2)as用来引导定语从句，全句的重心在主句，常译成“正如…一样”；而which引导定语从句，全句的重心在从句，常译成“这一点…”例如： As we know, he is an honest man． 正如我们所知，他是个诚实的人。(强调他是个诚实的人) He is an honest man，which we know． 他是个诚实的人，这一点我们都知道。(强调我们都知道这件事) that,which的用法练习 1. It was not until midnight they reached the camp site. A．that B．when C．while D．as 2. People in Chongqing are proud of they have achieved in the past ten years. A．that B．which C．what D．how 3.

It was the four years from , _____I spent studying for a master’s degree, _____I will never forget. A． that B. when C. that D. that 6. ―Where did you get to know the professor over there? ―It was at the workshop ____we did research together two years ago. A． that B. there C. which D. where 7. It was along the Mississippi River _______ Mark Twain spent much of his childhood. A．how B．which C．that D．where 8. Nancy enjoyed herself so much she visited her friends in Sydney last year. A．that B．which C．when D．where 9. Mr. Smith has not yet answered my question ____I can go with him to _____he calls the Underground Treasure House next week . A . which B . where C . that D . what 10. A commercial advertisement is one _____ has been paid for to promote a product or a service. A． where B. what C. when D. that 八、so与such的用法 1、so +be(助动词或情态动词)+主语，表示前面所说的情况也适用于另一个人或物， The boy died and a week later, so did his sister. I am an English teacher. So is my wife . 但若前面所提到的人或物是两个或两个以上的句子，并且其中既又肯定句，又有否定句；既含实意动词，又含系动词；主语既有表示人的，又有表示物的。这时应用“So it is (was) with”或”It is the same with”的句式。 Tom studies English well, but he isn\'t good at maths. So it is with Kate. Wang Lin is a Chinese girl, and China is her homeland. So it is with me. 2、so + 主语 + 谓语动词，用来表示对上文的情况给予进一步的肯定 。 ―It was cold yesterday. ―So it was. ―The students study hard. ―So they do . 3、主语+动词+so，这一结构译为“这样” 1) 主语+(does, did)do+ so He said he would tell me the news, but he did not do so . 2)主语+hope (expect, think, believe, suppose, imagine, afraid)+so ―Do you think his will come ? ―Yes ,I think so. ―Will it be fine tomorrow? ―I hope so. 注意：在用这一结构来代替否定概念时 ，既可用so，亦可用not，在动词believe，expect，suppose，imagine，think，guess 等的肯定形式后加not与否定形式后加so，两者在意义上没有区别。但在hope，guess，be afraid 后代替否定概念时只能是not，而不能用so。 ―Will you get the first prize? ―I\'m afraid not.(不说I\'m not afraid so.) 4、so + 形容词（副词）+that ,引导结果状语从句。 The book is so interesting that we all want to read it . I was so busy that I had no time to write a letter . 运用这一结构时要注意，可把so +adj (adv)提到句首，形成部分倒装。 So excited was the boy that he couldn\'t speak . 注意以上结构与定语从句的区别。如： This is such an interesting as everyone wants to see. (定语从句) This is as interesting a film as everyone wants to see. (定语从句） This is such an interesting film that everyone wants to see it. This is so interesting a film that everyone wants to see it. 5、后接复数形式或不可数名词，无论有无修饰语都用such，但是名词之前有few，many，little（少），much修饰时，应用so。例如： Such things often happen in our daily life. 　 Whales are such smart animals that they communicate with each other. Did you ever see such weather? 　 He made such rapid progress that he soon began to write articles in English It is very surprising that such little animals can eat so much food. 6、such 有时充当形容词，意思是“这（那）样的”。有时和all、some、other、another、one、no、many、any、few、several等词同时修饰一个名词，但它的位置通常是放在这些词的后面，例如： I have never seen such a beautiful place before. I have met many such people in my life. 　 One such dictionary is enough for me. We have had several such Chinese paintings already. No such thing has ever happened. so与such练习 1.

I am not sure _____ he has gone to ji’nan. 3、If 还有“如果”的含义，引导条件状语从句。 1）She will die if the doctor doesn’t operate immediately. 此时注意条件句的时态,用现在时表示将来。 2）注意if 和unless的差异。 Don’t come unless I call you. We will go out for a picnic __________ it rains. We will not go out for a picnic _______ it rains. 此时注意unless 的翻译“如果不…的话”，“除非…,否则…” 3）If 引导条件状语从句时，在意思明确时有些词可以省略。 If (it is) necessary, I will go to attend the meeting.
