【正文】 oney on sth.)，即根據(jù)定語從句的意義來確定介詞。This is my pair of glasses, without which I cannot see is the book for which you asked.=This is the book(that/which)you asked you know the person with whom I shook hands？= Do you know the person(whom/who/that)I shook hands with? The beginning of agriculture was a big step in human progress with which nothing could pare until our information the dark street, there wasn39。t a single person to whom she could turn for this the factory to which you paid a visit last week? Is this factory the one to which you paid a visit last week? This is the girl whom they are looking after.(介詞after與look構(gòu)成固定詞組，不可前置。look at, look for, look after, take care of, hear ofaboutfrom, care for, look forward, pay attention to, listen to等)●as 的用法:(as 引導(dǎo)定語從句, 在定語從句中作主語、賓語、表語)①如為限制性的，多用于the same …as。the same as；such …as …。as many/much as；so …as等結(jié)構(gòu)中。如：※I have the same book as you(have).我有一本和你的一樣的書。Her attitude to him was quite the same as it had always been.(關(guān)系代詞as和指示代詞same連用, 在從句中用作表語, 先行詞是same.).Why didn39。t you mention that in face of the police just now?I thought it was such a minor detail as was hardly worth will only discuss such problems as have something to do with our own 39。t do such things as you are not sure is no such place as you dream of in all this ：I live in the same house that he used to live 39。m wearing the same shirt as you wore ：Here is so big a stone as no one can lift.（定語從句）Here is so big a stone that no one can lift it.（結(jié)果狀語從句）②如為非限制性的，多單獨(dú)引導(dǎo)一個(gè)定語從句，這種定語從句可置于句首，句中或句尾，譯為“正如，這一點(diǎn)”。（動(dòng)詞常為know, see, expect, point out, etc.）As we all know, smoking is harmful to one39。s health.(as 作賓語)=As is known to all, smoking is harmful to one39。s health.（as 作主語）=It39。s known to all that smoking is harmful to one39。s health.=Smoking is harmful to one39。s health , as we all know.（as 作賓語）=Smoking, as we all know, is harmful to one39。 was a foreigner, as I knew from his accent.(賓語, 先行詞是前面整個(gè)句子)Ⅲ.關(guān)系副詞引導(dǎo)的定語從句: ●When 指時(shí)間，在定語從句中作時(shí)間狀語。其先行詞是表時(shí)間的名詞（如：time, day, week, tear, month, etc.）He came last night when I was will put off the piic until next week, when the weather would be ：先行詞為“時(shí)間名詞”，可用when引導(dǎo)定語從句，when在定語從句中作狀語；還可以用which或that 引導(dǎo)，which或that在從句中作主語或賓語。比較: I still remember the day when /on which my brother joined the army.（作狀語）Next month, when you will be in your hometown, is just around the still remember the days which/that we spent together.（作賓語）Next winter which/that you39。ll spend in Harbin, I39。m sure, 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(duì)where在定語從句中的用法有更好的了解，下面我就對(duì)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(huì)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(shí)點(diǎn)，對(duì)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?cè)诙ㄕZ從句中充當(dāng)?shù)某煞植煌?，所以我們?cè)谶x擇關(guān)系詞時(shí)就要區(qū)別對(duì)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
