1、 定语从句关系词选定1,that,which,who,whom,whose,where,when,why 分别的使用场合 各种关系代词的使用方法 a) 关系代词 who 的用法 i. who 的前行词必须是人,在从句中可以担任主语,往往也可以代替在从句中担任宾 语的 whom,但是它前边不能有介词,如果带了介词就必须用宾格的 whom: (介词+whom)This is the teacher who teaches us mathematics.She is the girl who (whom) I met at the party. (可以替代)She is the girl whom
2、(who) I went there with. (可以替代)She is the girl with whom I went there. (不可替代)ii. who,that 在很多情况下可以通用,但是有些情况只能用 who: 1. 先行词是 one, ones, anyone 的时候宜用 who.One who has nothing to fear for oneself dares to tell the truth.The ones who flatter me dont please me. Dont tell anyone about the news who oughtnt
3、to know it. Anyone who fails to finish the task given should be criticized. 2. 先行词为 those 的时候,宜用 who 为关系代词Those who were not fit for their work could not see the beautiful clothes made of the magic cloth. Those who want to go to the Great Wall sign up here.3. 当先行词有比较长的后置定语的时候I met a foreigner in the
4、 street yesterday who could asked me questions in Chinese.4. 一个句子中带有两个定语从句,其中一个定语从句的关系代词为 that,另一个则用 who.

5、 的用法 whose 是代词的所有格,它既可以代人也可以代物。当代物的时候,它相当于 of which. I saw a woman whose bag was stolen.Ill call a person whose father knows you.Which is the car whose owner you know?(Which is the car the owner of which you know) Please show me the book whose cover is red. (Please show me the book the cover of whic
6、h is red) c) 关系代词 that 的用法首先特别注意,that 只能用在限定性定语从句中,在非限定性定语从句中永远不能选用 that, 另外介词后边也不可用 that, 而是跟 which. 在限定性定语从句中,which 和 that 在代替物的时候,一般可以通用。The money that (which) is in the wallet is mine.有些情况下,只宜用 that,而不宜用 which i. 先行词是最高级形容词或者它前面有最高级形容词的时候This is the best that has been used against pollution.Engl
7、ish is the most difficult subject that you will learn during these years.ii. 先行词是序数词,或者它前面有一个序数词的时候 He is the last person (that) I want to see.

11、语从句中 which 和 that 在指代物的时候常常可以通用,但是有时只宜用 which 而不用 thati. 关系代词前面有介词的时候 This is the hotel in which you will stay.ii. 如果有两个定语从句,其中的一句的关系词是 that, 另一句宜用 which. Let me show you the novel that I borrowed from the library which was newly open to us.关系副词 when, where, why 的含义相当于“ 介词+ which“结构,因此常常和“介词+ which“
12、结构交替使用。例如: There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。Beijing is the place where(in which) I was born. 北京是我的出生地。Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗? that 代替关系副词,可以用于表示时间、地点、方式、理由的名词后取代 when, where, why 和“ 介词+ which“引导的定语从句,在口语中 that 常被省略。例如
13、: His father died the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。 He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。2 关系代词与介词,关系代词的省略 a) 关系代词和介词 介词放在关系代词的前面时,介词短语只能用 which 代物,和用 whom 代人This is the hero of whom we are proud.I want to
14、find the very pen with which I wrote that letter.当介词放在句子的末尾时,可用 that/which 代物,that/whom/who 来作为介词的宾语, 且这个做介词宾语的关系代词往往忽略 This is the hero that (who/whom/忽略) we are proud of. b) 关系代词的省略首先注意只有限定性定语从句才能省略,非限定性定语从句绝对不能省略。在下列情况下,可以省略关系代词。i. 当关系代词在从句中担任动词宾语的时候The people (who) we met at the party were very
15、friendly to us.ii. 关系代词在从句中作介词,而介词在句尾时 Here is the man (that) you have been looking for.iii. 关系代词在从句中作表语时 Shang Hai is no longer the city (that) it used to be.iv. 在 there be 句型中,和先行词为 way 时,关系代词总是省略 There is an old man (who ) wants to see you.

16、 有些动词 +介词所组成的短语动词,关系非常紧密,介词不能前置 定语从句注意事项 a) one of + 复数名词 +关系代词 +复数型动词 the (only) one of + 复数名词+关系代词+ 单数型动词The Great Wall is one of the world-famous buildings that draw lots of visitors. Titanic is the (only) one of the most wonderful movies that has been produced in Hollywood. b) What 不能用于定语从句中。as,
17、 which 非限定性定语从句 由 as, which 引导的非限定性定语从句,as 和 which 可代整个主句,相当于 and this 或 and that。As 一般放在句首,which 在句中。例如: As we know, smoking is harmful to ones health. 如我们所知,吸烟有害健康。The sun heats the earth, which is very important to us. 太阳使地球暖起来,这对我们人类很重要。先行词和关系词二合一 1) Whoever spits in public will be punished here
18、. ( Whoever 可以用 anyone who 代替) 2) The parents will use what they have to send their son to technical school.(what 可以用 all that 代替)what/whatever; that/what; who/whoever 1)what = the thing which; whatever = anything。例如: What you want has been sent here. 你要的动词都送来了。Whatever you want makes no difference
19、to me. 不管你要什么,跟我没什么关系。2) who= the person that whoever= anyone who。例如: (错) Who breaks the law will be punished. (错)Whoever robbed the bank is not clear. (对) Whoever breaks the law will be punished. 王子犯法,与庶民同罪。对Who robbed the bank is not clear. 谁抢了银行还不清楚。 3) that 和 what 当 that 引导定语从句时,通常用作关系代词,而引导名词性从句时,是个不充当任何成分的连接词。宾语从句和表语从句中的 that 常可省略。What 只能引导名词性从句,用作连接代词,作从句的具体成分,且不能省略。例如: I think(that)you will like the stamps. 我想你会喜欢这些邮票的。 What we need is more practice. 我们需要的是更多的实践 这些应该足够掌握了
