There are few places where he has never go(=to which).注意:先行词是“地点名词”,如在从句中作主语,表语或宾语,关系词用which/that/as, 作状语用where或介词+ which。That is the factory which/that produces 100,000TV sets a year.That is the factory where/in which his father once worked. 3why1)先行词是 reason,关系词在从句中作状语用why或for + which。作主语,表语或宾语,用which/that/as, This is the reason that he told me yesterday. This is the reason why/for which he was late for the meeting. 2)当主句主语是reason时,作主句表语的成分不能有because和because of 。其结构一般为the reason whyis that,或者 the reason that is that,如: The reason why he was absent was that he was ill.The reason that he told us for his absence is that he was ill.(三)介词+关系代词 (介词+which/whom/whose)当关系代词作介词宾语,且该介词不是和从句的谓语动词构成固定短语时,介词可以提前,这样就出现"介词+关系代词"。先行词指物,用"介词+which/whose", 指人则用"介词+whom/whose", 且关系代词均不能省略.The pen with which I wrote is broken.The man about whom I told you just now is my neighbour.This is Mr. King, in whose factory I work.介词的选择要遵循以下原则: 1)根据定语从句中谓语动词与先行词的搭配内容而定。The woman _ whom he is talking is his headmaster.2)、根据定语从句中形容词与介词的固定搭配He referred me to some reference books _ which I am not very interested.3)根据先行词而定。He has not reached the age , _ which he can marry.4)根据“介词+关系代词”在主从句中的作用及意义。Water, _which man can not live, is very important for us.the way做先行词时,定语从句用 in which或that 引导,也可以不用关系词。Eg. I dont like the way ( in which/that )you speak to your mother.注意:含有介词的短语动词不能拆开,介词仍然放在动词之后。This is the pen that/which he is looking for. the+ 名词+of+关系代词表示所有关系知识归纳:此时,指人的关系代词只能是whom, 指事物的关系代词只能是which。该结构表示所有关系, 口语中常用“whose + 名词”代替。非正式文体中可以用“of which/whom+ the +名词”。 1) Recently I bought an ancient Chinese vase, _ was very reasonable. A. which price B. the price of which C. its price D. the price of whose 2)This is the boy _the bike was stolen yesterday.A. whom B. whose C. of whom D. of whose表示部分的词语of关系代词 ,表示整体与部分的关系知识归纳:此时,指人的关系代词只能是whom, 指事物的关系代词只能是which。表示部分的词语常见的有:不定代词all, both, none, neither, either, some, any; 数词(含基数词,序数词,分数和百分数);数词+名词;the +最高级/比较级;以及表示数目或数量的词语many, most, few, several, enough, half a, a quarter等。 二 as引导的定语从句1. 在限制性定语从句中,当先行词与as,so,such,the same 连用时,常用关系代词as来引导定语从句, as 在从句中充当主语,宾语,表语。 I want to have such books _ you have. A. which B. that C. what D. as I know as many people_are present at the meeting. A.that B.whom C.who D.as1) the same. as 和 the same .that的用法辨异.Thats the same tool as I used last week.(同类事物)Thats the same tool that I used last week. 那就是我上周用过的工具。(指原物)2).such/so.as和such/so.that的用法辨异.It is such an interesting book/so interesting a book _we all like.It is such an interesting book/ so interesting a book _ we all like it. A. that B.it C.as Dwhich2.as引导的非限制性定语从句可位于句首,也可位于后面。(代替主句整个内容)_is mentioned above, the number of the students in senior high school is increasing. A. Which B. As C . That D. It .He did the experiment successfully, _had been expected.A. that B.it C.as D.what三 as和which引导的非限制性定语从句的区别1.as引导的从句与主句是一致关系,as常解释为“正如.的那样”, “ 正像.”。从句可位于句首,句中或句末。 常用于:as is known to all, as we all know, as often happens, as has been said before, as was expected, as is said above, as is mentioned above, as is reported in the newspaper等结构中。As is often the case, we have worked out the production plan.The earth goes around the sun, as everyone can see.2.用which的情况1)当从句的谓语是否定形式或表示否定意义时,只能用which。He made a long speech at the meeting , which we had not expected./which was unexpected.2).当从句的谓语后接一个复合宾语时,只能用which。He admires everyone in the class, which I find quite strange.3)which引导的从句与主句是因果关系或主句是对从句的评论,常解释为“这,这一点”,Tom didnt pass the exam, which made his parents very disappointed.He must come from the north, which can be judged from his accent.注意:which引导的非限制性定语从句,从句只能位于主句之后。四定语从句与其他句型的区分1定语从句与并列句 用一个恰当的词完成下列句子,使之完整与正确。 Mr Li has three daughters, none of _ is an engineer Mr Li has three daughters, but none of _ is a dancer Mr Li has three daughters; _ are doctors 2 as 引导的非限制性定语从句与it引导的句子。The earth is round, and_ is known to all.
