(2000年)A. what has he achieved B. that what he had achievedC. what he had achieved D. that he had achieved解析：答案选C。at是介词，其后接宾语从句时，从句要用陈述句的语序。achieve是及物动词，what在从句中作宾语，所以选C。that

15、在从句中只起连接作用，无意义。2. _ I saw was two men crossing the street. (2001年)A. What B. Whom C. Who D. That解析：答案选A。本句中的主语是主语从句，what在从句中作宾语。3. Mary found it difficult to talk calmly about which she A B C had experienced at the station. (2002年)D解析：答案选C。what 引导宾语从句，what在从句中作experience的宾语。C应改为：what。4. Would the ne

16、ws _ he failed to pass the exam bother you? (2003年)A. which B. that C. of which D. on which解析：答案选B。由于从句he failed to pass the exam 是news的内容， 所以这是一个同位语从句，应该用that引导。5. The fact _ he does so in so short period of time challenges explanation. (2003年)A. why B. that C. what D. which解析：答案选B。fact后的从句讲的是fact的

17、内容，所以是同位语从句，引导同位语从句的连词只能使用that。6. The old gentleman never fails to help _ is in need of his help.A. whom B. who C. whoever D. whomever解析：答案选C。本句中需要填入一个连接代词引导宾语从句。且此代词要在从句中作主语。A、D都只能作宾语。whoever引导宾语从句。who也可以引导宾语从句，但whoever强调无论谁。7. _ was unimportant。(2000年)A. Whether he enjoyed our dinner or not B. No

18、matter how he enjoyed our dinnerC. If he enjoyed our dinner D. What he enjoyed our dinner解析：答案选A。本句中包含一个主语从句，意思是“他是否喜欢我们的饭不重要。”只有A最符合题意。B、C中的no matter how 和if 都引导状语从句；D项中的what在从句中作主语或宾语，而本从句中有主语和宾语。8. How long do you think _ to finish this urgent task?A. did it take you B. it will take you C. will i

19、t take you D. it to take you解析：答案选B。think后接宾语从句。从句不倒装。9. _ was not the way the event happened.A. Which the press reported B. That the press reportedC. What did the press report D. What the press reported解析：答案选D。此处需填入一个主语从句。在这个主语从句中作动词report的宾语应该用连接代词what。10. No one doubts _ it is true.A. whether B.

20、if C. that D. what解析：答案选C。doubt用在肯定句中后接if引导的从句；用在否定句中后接that引导的从句。定语从句 定语从句是将定语扩大成一个完整句子，由关系代词或副词引导，放在所要修饰的名词之后，通常称被修饰的名词为先行词。 他是从美国来的英语老师。 He is an English teacher from America. 形容词 介词短语 他 是 那个下学期要教我们的英文老师。 主 系 定语从句 表语 定语从句 He is an English teacher who will teach us next term. 先行词 关系代词在从句中做主语 由关系代词引

21、导的定语从句who代替人,在从句中做主语或宾语。which代替物，在从句中做主语或宾语。whom代替人，在从句中做宾语。that可以与who which whom换用。 他 是 去年教我们英语的老师。 主 系 定语从句 表语 定语从句 He is a teacher who (that) taught us English last year. 先行词 关系代词在从句中做主语 这 就是 我们老师写的那本书。 主 系 定语从句表语 定语从句 This is the book which(that) was written by our teacher. 先行词 关系代词在从句中做主语 这 就是

22、我在晚会上遇见的女孩。 主 系 定语从句 表语注意 ！- 定语从句中用which定物而不what, 不要与在名词性从句混淆。 1. I dont know the book which you wrote2.I dont know the book what you wrote. 定语从句 That is the girl whom(that/who) I met at the party. 先行词 关系代词在从句中做met的宾语 你刚才与之说话的男孩 哪去了？ 定语从句 主语 表语 定语从句 介词后的关系代词注意 ！- 有时关系代词在从句中不是做动词的宾语而是做介词的宾语。在这种情况下，通常

23、有几种表达方式。 我认识你们谈论的那个人。 定语从句 I know the man whom(who/that)you are talking about. 先行词 关系代词在从句中做介词about的宾语注：关系代词做介词about的宾语，about被保留在句尾时，关系代词可以用whom who或that，可以省略。我们也可以将about放在关系代词whom之前。 定语从句 I know the man about whom you are talking. 先行词 关系代词在从句中做介词about的宾语注：当about放在whom之前时，whom不能被省略，也不能用who或that代替who

24、m.请看例句： 这就是你正在找的女孩吗？Is this the girl who(whom/that)you are looking for? Is this the girl for whom you are looking?注意 ！- 必须使用关系代词that的几种情况1、 先行词被形容词最高级修饰。 This is the worst book that I have read. He is the tallest man that I know.2、 先行词是all, everything, nothing, something等不定代词 He told me all that he

25、knew.3、 当先行词被only, any, no, very, little或序数词修饰时。 That is the only way that leads into the mountain. Who is the first student that came here?注：上面3种情况不能使用who, whom, which等关系代词。 当that在从句中做宾语时，可以省略。4. 在一些抽象名词如：way idea 注意 ！- 在学习定语从句 时，请注意关系代词和关系副词的区别，关系代词在从句中起到的是名词的作用，而关系副词起的是副词或介词短语的作用，即状语的作用。 关系副词WHEN

26、-代替时间WHERE-代替地点WHY-代替原因 WHEN I will never forget the day. On the day, my father died. I will never forget the day when my father died. 先行词 关系副词在从句中做状语从以上的例句中可以看出，关系副词在从句中代替的是一个介词短语，相当于on the day，做状语。该句也可以用关系代词来做。请注意关系代词与关系副词的区别。 I will never forget the day on which my farther died. 先行词 关系代词在从句中做介词on

27、的宾语 I will never forget the day (which) my farther died on.WHERE Look at the house. In the house, I was born. Look at the house where I was born. 看，那就是我出生的房子。注：where在从句中充当状语，代替in the house，该句也可以用关系代词来做。Look at the house in which I was born.Look at the house (which) I was born in.注意 ！-关系代词在从句中起到的是名词的

28、作用，而关系副词起的是副词或介词短语的作用，即状语的作用。1. Look at the house (which) I was born in.2.Look at the house where I was born in. WHY I know the reason. She is unhappy for the reason today. I know the reason why she is unhappy today.关系副词why代替从句中for the reason。此句可以用关系代词做。 I know the reason for which she is unhappy to

29、day. I know the reason (which) she is unhappy for today.注意 ！- as引导定语从句，先行词可以是一个名词，也可以是一个短语或一个句子。as本身含有“像”的意思，而从句的位置不一定要在先行词之后 定语从句 The earth moves around the sun, as you know. 先行词是整个句子 关系代词做know的宾语 代替前面整个句子 (As you know, the earth moves around the sun.)正像你所知道那样地球围绕太阳运行。 非限定性定语从句当定语从句与所定的名词在意思上并不十分紧密

30、时，通常使用非限定性定语从句，也就是在先行词与定语从句之间加“，”号。这种句子在汉语中我们习惯用两句话表达，而英语习惯用非限定性定语从句表达：China, whose population is the largest in the world, lies in East Asia. 中国位于东亚，它是世界上人口最多的国家。 Mary will spend her holiday in London, where her boy friend works. 玛丽要在伦敦度假，她的男朋友在那里工作。注意 ！- 在非限定性定语从句中不使that1. An old friend from abroa

31、d, whom I was expecting to stay with, telephoned me from the airport.2.An old friend from abroad, who I was expecting to stay with, telephoned me from the airport.3.An old friend from abroad, that I was expecting to stay with, telephoned me from the airport. 定语从句与同位语从句的区别 The news that she is going

32、to marry an American is surprising. 同位语从句 她要嫁给一个美国人的消息令人吃惊。注：句中的that是连词，在从句中没有语法成分。该句与news并列，是同位语从句。 The news that he told me is not true. 定语从句 他告诉我的那个消息不是真的。注：句中that是关系代词，在从句中做told的宾语，引导的是定语从句。注意 ！- 请同学们将下列练习重新做一遍,这一点非常重要。课堂练习定语从句典型试题1. An old friend from abroad, _ I was expecting to stay with, tel

33、ephoned me from the airport. (2000年)A. that B. whom C. who D. which2. This is one of the best books _ on the subject.

Helen was much kinder to her youngest child than she was to the others, _, of course, made the others jealous. (2005年)A. who

37、B. what C. that D. whichkey-定语从句典型试题1. An old friend from abroad, _ I was expecting to stay with, telephoned me from the airport. (2000年)A. that B. whom C. who D. which解析: 答案选B。whom, 关系代词，在定语从句中做with的宾语，指人。本句中的定语从句是非限制性定语从句。that不引导非限制性定语从句。2. This is one of the best books _ on the subject. (2000年)A.

38、 that have ever been written B. which have ever been writtenC. that has ever been written D. whatever have been written解析: 答案选A。因为先行词books前有形容词的最高级best修饰，所以只能用that引导定语从句，选A。当先行词前有形容词最高级、only或very修饰时，要用that引导这个定语从句。定语从句中的谓语和先行词保持一致。3. The United States is composed of fifty states, two of those are A

39、B separated from the others by land or water. (2000年)C D解析: 答案选B。应改为：two of which。在非限制性定语从句中，限定词some, any, none, all, several以及表示数量的词可与of whom, of which连用。先行词是物用of which; 是人用of whom。本题中which指fifty states。4. A curve曲线is a line _ no part is straight and which has no angle. (2001)A. that B. whose C. in

40、 which D. of which解析: 答案选D。 “介词+关系代词”可引导定语从句。No part of 是固定短语，因此用of which, 而不用in which。5. Before joining the army, he spent a lot of time in the village _ he belonged (2001年)A. to which B. which C. to where D. at which解析: 答案选A。belong是不及物动词，其后接to之后才接宾语，belong to:属于。因此选to which。where是关系副词，不能置于介词之后。to

41、which引导的从句是定语从句。6. The experiment, _ will soon be announced, was done by my colleagues. (2001年)A. whose results B. the results on which C. at which the results D. of whose results解析: 答案选A。此句为非限制性定语从句。关系代词whose在从句中作results的定语。whose是代词的所有格，它既可以代人也可以代物。7. _ is known to all, too much smoking will cause

42、lung cancer. (2003年)A. That B. It C. As D. What解析: 答案选C。as 引导的是一个非限制性定语从句。as代替后面提到的句子。8. Do not trust such men _ often like to praise you to your face. (2004年)A. who B. that C. as D. they解析: 答案选C。当先行词被such修饰时其后的定语从句要用as引导。9. In his latest article Tom criticizes the way which the war A B C is being h

43、andled. (1997年)D解析: 答案选C。名词way后接定语从句时要用that引导。C改为：that。10. Helen was much kinder to her youngest child than she was to the others, _, of course, made the others jealous. (2005年)A. who B. what C. that D. which解析: 答案选D。本题考察非限制性定语从句。关系代词which指代前面整个句子。在从句中作主语。状语从句状语从句是将以前学过的主谓宾状句型中的状语扩大成一个完整的句子，并用连词引导。准

44、确掌握每一个连词的含义是掌握状语从句的关键。同时要注意主从句时态呼应。 时间状语从句 引导时间状语从句的连词有when, while, as, the moment, before, after, till, until, since, as soon as , by the time 等。请注意when, while ,as 的区别。when-1.当.的时候 通常指某一特定的时间,主句与从句的动作同时发生。 When I opened the window, I saw him come up. 注：如果时间状语从句中，主从句都是将来的动作或状态时，英语习惯上主句用将来时，从句用一般时。wh

45、en-2.正在.的时候，突然.。 通常主句是进行时或to be about to时，在翻译的时候，when可以译成没想到或突然。 I was walking along the street, when I met him. 我正在街上走突然遇见了他。when-3.当从句是进行时,主句是一般时,往往表示不满. Someone knocked at the door when I was having breakfast. 我在吃早饭的时候，真烦人，有人敲门。1A当when引导的从句是进行时，主句的动作有一种不满的情绪，这句话应该译成：当没有人注意他的时候，他却偷偷地while-1.在.期间 往

46、往指一段时间。 While we were in America, we saw him twice. 我们在美国期间，见过他两次。while-2.表示一种不满情绪 意思是这边在干某种重要的事，而另一边在享受等。 The soldier faces the powder while the beauty powders the face. 前方吃紧，后方紧吃。（战士面对炸药，美人在往脸上擦粉。）as-1.一边.一边，随着 She was doing her homework as she was listening ti the music. as-2. 指一个动作紧接着一个动作发生，从句通常

47、用进行时。 (不能用when因为两个动作不是同时发生) As I was going out, it began to rain. 我刚要出去，天就下雨了。the moment 一就(=as soon as) Did you remember to give Mary the money you owed her?not.until-直到.才 He didnt leave the office until he finished the work. 直到他干完工作，才离开办公室。 =He left the office when he finished the work.Before-在.之前
