【文章內(nèi)容簡介】 ure, will be shall never forget the day when Shen Zhou Ⅴ was launched, which has a great effect on my are occasions when joking is not permissible.●Where 指地點(diǎn)，在定語從句中作地點(diǎn)狀語。其先行詞是表示地點(diǎn)的名詞，如：place, school, factory, room, is the place where I was live in the room where /in which he used to ：先行詞是“地點(diǎn)名詞”，定語從句可用where引導(dǎo)，還可用which或that引導(dǎo)，which/that 在從句中作主語或賓語。比較: ※This is the factory where /in which he worked last year.（作狀語）在高中的英語學(xué)習(xí)中，我們都知道，where在定語從句中用作關(guān)系副詞，作狀語，先行詞一般指地點(diǎn)。例如：This is the farm where we worked when we were 。He met his wife in the park where they fell in love with each ，就是在那里，他們相愛了。當(dāng)然，在實(shí)際的英語學(xué)習(xí)中，where在定語從句中的用法遠(yuǎn)不是這么簡單，相反，要復(fù)雜得多，為了讓學(xué)生對where在定語從句中的用法有更好的了解，下面我就對學(xué)生在學(xué)習(xí)過程中的重難點(diǎn)問題談一談它的用法。一、某些在從句中充當(dāng)?shù)攸c(diǎn)狀語的“介詞+關(guān)系詞”結(jié)構(gòu)可以與where 互換，where=in/at/on/...which 例如：This is the house in which I lived two years 。This is the house where I lived two years ，并不是單純地讓學(xué)生知道where的這種用法就可以了，很多時(shí)候?qū)W生要掌握where和其他詞的用法的區(qū)別，才能更好地把握定語從句的用法。例如： This is the factory where/in which you worked last is the factory that/which/you visited last ，關(guān)系詞在定語從句中作狀語，所以用關(guān)系副詞where或者in which，因?yàn)槎ㄕZ從句中worked 是個(gè)不及物動(dòng)詞；而在第二句中，關(guān)系詞在定語從句中做賓語，因此用that或which，還可以省略，visited是個(gè)及物動(dòng)詞。學(xué)生有時(shí)還會碰到更復(fù)雜的情況。例如： Is this factory the one that/which/ you visited last year? Is this factory the one where/in which you lived last year? Is this the factory where/in which you lived last year? 這幾個(gè)句子比前面的兩個(gè)句子又復(fù)雜，除了要區(qū)別關(guān)系詞在定語句子作什么成分，還要注意到前兩個(gè)句子缺成分，所以要補(bǔ)充 the one。二、where定語從句修飾抽象名詞where引導(dǎo)的定語從句的先行詞大多數(shù)情況下是表示地點(diǎn)的名詞，但也有特殊情況。如果定語從句修飾point，situation，part，condition和case等表示抽象意義的詞，關(guān)系詞在定語從句中充當(dāng)狀語時(shí)，常用where 引導(dǎo)，意思是“到了某種地步，在某種境況中”。為了幫助同學(xué)們熟悉這一語言現(xiàn)象，正確掌握這一知識點(diǎn)，對where定語從句修飾抽象名詞的用法作一歸納。1)where定語從句修飾抽象名詞point You reach a point where medicine can’t 。We have reached a point where a change is 。注：有時(shí)point也可以是具體的地點(diǎn)：The accident happened at the point where the A15 joins the 。2)where定語從句修飾抽象名詞case There are cases where the word “mighty” is used as an ，mighty一詞可用作副詞。3)where定語從句修飾抽象名詞activity Those successful deaf dancers think that dancing is an activity where sight matters more than ，舞蹈是一種讓人看勝過讓人聽的活動(dòng)。4)where定語從句修飾抽象名詞situation He got into a situation where it is hard to decide what is right and 。5)where定語從句修飾抽象名詞position It’s put me in a position where I can’t afford to take the 。6)where定語從句修飾抽象名詞job She wants a job where her management skills can be put to good 。當(dāng)然了，我們碰到這些詞作為先行詞時(shí)并不一定都用where，我們也要具體情況具體分析，他們只有在定語從句中作狀語時(shí)才用where。例如：We are trying to reach a point ____ both sides will sit down together and you have anything to say for yourself?Yes, there’s one point ____ we must insist D./ 上面兩個(gè)句子雖然先行詞相同，都是point，但是由于他們在定語從句中充當(dāng)?shù)某煞植煌?，所以我們在選擇關(guān)系詞時(shí)就要區(qū)別對待。第一個(gè)句子中關(guān)系詞在句中作狀語，所以選擇where關(guān)系副詞；第二個(gè)句子中關(guān)系詞在定語從句中做賓語，所以選擇關(guān)系代詞that，which或者不填，這樣第一題選擇C，第二題選擇D。The treatment will continue until the patient reaches the point where he can walk correctly and think you have got to the point where a change is needed, or you would reports, legal papers and most business letters are the main situations where English is 39。s got himself into a dangerous situation where he39。s likely to lose control of the small mountain village where we spent our holiday last month lies in what /the place which is now part of is the park which/that they visited last year.（作賓語）Not having been there before, he simply had no idea about the place, which everyone says is worth visiting.●Why 指原因，在定語從句中作原因狀語。先行詞為reason 時(shí)，可用for which指代；當(dāng)關(guān)系詞在從句中作主語或賓語時(shí)，則用which或that 引導(dǎo)。如：The reason why / for which /(that)he didn39。t attend the meeting was that he was don39。t believe the reason(that/which)he gave me.（作賓語）Have you asked him the reason that may explain his success?（作主語）Ex.)He was 39。s because he got up late..He got up 39。s why he was late.(表語從句)(the reason)why/for which he was late.(定語從句)當(dāng)先行詞為way時(shí)，定語從句常用that, in which,或不用引導(dǎo)。way后的定語從句 的引導(dǎo)詞不用時(shí)較多。但如果關(guān)系詞在句中作主語或賓語時(shí)，則用which或that 引導(dǎo)。如: This is the way(that)/in which I do such : Please do the experiment in the way（that/which）I have shown you.Ⅳ.限制性定語從句與非限制性定語從句的區(qū)別： ，非限制性定語從句往往用逗號隔開。，限制性定語從句與先行詞關(guān)系緊密，起限定作用，如果去掉了這個(gè)定語從句，整個(gè)句子就不完整或者會改變意思；而非限制性定語從句與先行詞關(guān)系不是很緊密，對先行詞起補(bǔ)充說明或描述的作用。This is the book I like 。Beijing, which has been China39。s capital for more than 800 years , is rich in cultural and historic ，它有著豐富的文化和歷史遺產(chǎn)。，限制性定語從句可譯為一句（較短的一般譯為“的”字結(jié)構(gòu)）；而非限制性定語從句可譯為兩句。（見上句翻譯）比較: He has a sister, who is a has a sister who is a ，指人時(shí)用who, whom, whose , 指物時(shí)用which , whose。關(guān)系副詞when，where, why, studied hard at school when he was young, which leads to his success in his later 39。s father, who arrived just now, is a famous set up a separate state of their own, where they would be free to keep Negroes as was proud, which his brother never was.Ⅴ.幾個(gè)易混淆的關(guān)系代詞的比較: ●that amp。 which: 在定語從句中，which 和that 在指代事物時(shí)，一般可以互換使用，但并非在任何情況下都是這樣，這里介紹宜用that, 而不宜用which 的情況.①先行詞為不定代詞,all,much,something,everything,anything,nothing,none,the one等, should do all that is useful to the 39。s nothing that can be said about you mean the one that was bought yesterday? ②先行詞被only, any, few, little, no, just, very, one of等詞修飾時(shí)。 only thing that we could do was to 39。s the very word that is wrongly last place(that)we visited was the chemical can take any(=whichever)seat that is hope the little that I can will be of some help to *This is one of the best novels that were published last year.*This is the only one of the best novels that was published last year.③先行詞是序數(shù)詞時(shí)或被序數(shù)詞修飾時(shí)。 we talk about Wuxi, the first that es into mind is Tai is the third film that has been shown in our school this term.④先行詞是最高級或被最高級修飾時(shí)。 is the best that can be done most important thing that should be done right now is how to stop him from going on.⑤先行詞既有人又有物，用which和who都不適合，： writer and his novel that you have just talked about is really well rider and his bike that had run over an old woman were held up by the police.⑥ I caught two fish and put them in a basin of you can see the two that are still alive.⑦如果有兩個(gè)從句，其中一個(gè)關(guān)系代詞已用which ,另一個(gè)關(guān)系代詞宜用that，以避免語言的單調(diào)或重復(fù)。Edison built up
