　　定語從句講解：從句缺主語時，引導詞都可以用什么，which 和that 在什么時候可以互換，什么時候不 定語從句從句缺主語時，引導詞都可以用什么，which

　　和that 在什么時候可以互換，什么時候不可以

　　1.當先行詞是everything, anything, nothing (something 除外), all, none, few, little, some等代詞時，或當先行詞受every, any, all, some, no, little, few, much等代詞修飾時。如：

　　Have you taken down everything that Mr. Li said? 李老師講的你都記下來了嗎?

　　There seems to be nothing that is impossible to him in the world. 對他來說似乎世界上沒有什么不可能的事。

　　All that can be done has been done. 所有能做的都做好了。

　　There is little that I can do for you. 我不能為你干什么。

　　He stayed in the library and looked up any information that they needed. 他呆在圖書館查找所需的資料。

　　注意：當先行詞指人時，偶爾也可用關系代詞who，如：

　　Any man that / who has a sense of duty won’t do such a thing. 任何有責任感的人都不會做這樣的事。

　　All the guests that / who were invited to her wedding were important people. 所有應邀來參加她婚禮的客人都是重要人物。

　　2.當先行詞被序數(shù)詞修飾時。如：

　　The first place that they visited in London was the Big Ben. 在倫敦他們參觀的第一個地方是大本鐘。

　　3.當先行詞被形容詞最高級修飾時。如：

　　This is the best film that I have ever seen. 這是我看過的最好的電影。

　　4.當先行詞被the very, the only修飾時。如：

　　This is the very dictionary that I want to buy. 這正是我要買的詞典。

　　After the fire in his house, the old car is the only thing that he owns. 家里發(fā)生了火災過后，那輛舊車成了他的唯一擁有。注意：當先行詞指人時，偶爾也可用關系代詞who。如：

　　Wang Hua is the only person in our school who will attend the meeting. 王華是我校唯一出席會議的人。

　　5.當先行詞前面有who, which等疑問代詞時。如：

　　Who is the man that is standing by the gate? 站在門口的那個人是誰?

　　Which is the T-shirt that fits me most? 哪件T恤衫最合我的身?

　　6.當先行詞為人與動物或人與物時。如：

　　They talked about the persons and things that they remembered at school 他們談論著他們所能記起的在校時的人和事。

　　Look at the man and his donkey that are walking up the street. 瞧瞧那個沿街走來的人和他的毛驢

　　Which引導的定語從句在語法和語用功能有利于區(qū)別于that引導的定語從句的鮮明特色。

　　一、語法要點。

　?、儆袑掗煹闹复秶?。不僅可措代主句中某一先行詞___名詞(A)，還可以指代主句中某些句子成分，如不定式賓補，不定式賓語，動賓結構等(B)，甚至整個主句

　　(C)。后兩項功能是that所沒有的。

　　(A)The computer which(=that) I bought yesterday is home made.

　　(B)Yesterday I asked him to go to the cinema with me, which agreed(昨天我要他同我一道去看電影，他同意了)。

　　He wishes to get quick rich without any labour, which we think only Wishful thinking (他想不勞而獲，迅速致富，我們認為這是想入非非)。

　　(C)The sun heats the earth，Which is very important to living things(太陽曬熱地球，這對于萬物是十分重要的)。

　?、诜窍薅ㄐ远ㄕZ從句中，無論主語還是賓語，關系代詞用which不用that;即使which作賓語也不省去。

　　Football, which is very interesting, is played all over the world.

　　I never give up learning foreign languages. Which I fink to de a bridged to the world(我從沒有放棄過外語學習，因為我發(fā)現(xiàn)外語是通向世界的橋梁)。

　　(比較下一句關系代詞作賓語可省去的限定性定語從句。二者在這一點上的區(qū)別一目了然：It is the computer (that /which) I bought last week.)

　?、?ldquo;介詞+關系代詞”引導定語從句有一下四點值得注意。

　　A:當介詞前置時，關系代詞用which而非that;而且which不省去。

　　The pencil with he was writing broke.

　　無The pencil with that he was writing broke;也無The pencil with he was writing broke.

　　(注：當介詞后置于定語從句動詞后面，并且從句是定性的，關系代詞which, that可互換，能省略。This is the room which/that the great man once worked in.)

　　B:先行詞表示時間，定語從句可用關系副詞(when;先行詞表示地點，定語從句可用關系副詞where:

　　We’ll never forget the day on which (-when )we visited the Great wall.

　　They went to the village where(-at which )the oil well was located定位)。

　　C：此結構再延伸，出現(xiàn)“名詞/代詞+of/among+關系代詞”的格局，名詞又有數(shù)量意義，如“許多，一些，大部分，20個等”，則整個短語譯作“其中許多;其中一些…”：

　　On the crowded bus were school children, many of whom were from Beijing.

　　也可以把名詞/代詞稱到關系代詞后面，整個短語的功能不變：

　　He borrowed from the library novels and magazines, among which some are in English.

　　D:此延伸結構若是“名詞+介詞of+關系代詞”的格局，名詞無數(shù)量意義，則同于whose+名詞：

　　He lives in the house the doors of which face the south,=He lives in the house whose doors face the south.

　　二、語用功能。

　　Which定語從句(尤其是非限定性的)主要還是在語用功能上呈現(xiàn)that定語從句所沒有的亮點。

　　①表達主從句因果關系。

　　A Jew. Albert Einstein had to flee Germany. Which then was ruled by Hitler(愛因斯坦只得逃離德國，因為當時的德國是在希特勒的統(tǒng)治之下)。

　　NMET’99：Cory Luxmoore arrived from England to deliver the diary of his ancester to the Library Company,____he and his wife considered to be the best home for the diary (Cory Luxmoore(千里迢迢)從英國趕來把祖先的日記交給(費城)圖收館公司，是因為他和妻子認為該圖書館才是此日記最好的歸宿處)。

　　②表達主從句目的關系。

　　The Southern States set up a separate state of their own, in which they would be free to keep Negroes as slaves(南方各州卻反叛建立一個獨立王國，以便好繼續(xù)維持奴隸制度)。

　　③表達主從句讓步關系。

　　Einstein, who could have been very rich, cared for little money(愛因斯坦原本可以是非常富有的，但他卻不愛錢)。

　　He gave up his cause in which he had been very successful and joined in our project(他的事業(yè)盡管干得很出色，他還是放棄了，加入到我們的課題研究中來)。

　?、鼙磉_主句動作產(chǎn)生的結果。

　　⑤表示主從句條件關系。

　　⑥表示主從句時間關系。

　　⑦對主句內容作補充說明。
