which修飾句子

　　which一詞在科技英語(yǔ)中應(yīng)用極為廣泛,是科技英語(yǔ)中使用比較頻繁的語(yǔ)法修飾成分,它的使用使句子變得更長(zhǎng)更復(fù)雜。下面小編就來(lái)介紹下which修飾句子的用法。

　　只能使用which的情況:

　　1. 在“介詞+關(guān)系代詞”結(jié)構(gòu)中，關(guān)系代詞必須用which。如：

　　The house in which we live is very large. 我們住的房子非常大。 This is the reference book of which the teacher is speaking. 這就是老師正在談及的那本參考書。

　　注意： 如果介詞不放在修飾事物的限定性定語(yǔ)從句的句首， which就可換為that， 如：

　　This is the question which/that we’ve had so much discussion about. =This is the question about which we’ve had so much discussion. 這就是我們已經(jīng)多次討論過(guò)的問(wèn)題。

　　2. 先行詞為“those+表事物的復(fù)數(shù)名詞”時(shí)， 關(guān)系代詞通常只用which而不用that。如：

　　you should grasp well those skills which may be used in the future work. 3.如果先行詞是that,關(guān)系代詞應(yīng)用 which。 I have that which you gave me.

　　4.一個(gè)句子中如有兩個(gè)定語(yǔ)從句,第一個(gè)定語(yǔ)從句用了關(guān)系代詞that,第二個(gè)從句中的關(guān)系代詞宜用which，但在平行結(jié)構(gòu)中,應(yīng)重復(fù)同一個(gè)關(guān)系代詞，如： This is the book that you bought which you have lost.

　　I have a house which is located on the hillside, which faces the south. 5.如先行詞和定語(yǔ)從句之間被其它較長(zhǎng)的成分分隔,常用which?

　　Larry told her the story of the young airman which I narrated at the beginning of this book. (先行詞為story)

　　特殊情況：當(dāng)先行詞是表示原因或方式的名詞時(shí)，可以用that引導(dǎo)定語(yǔ)從句，相當(dāng)于介詞+which，that可以省略。

　　如： She likes the child for the very reason that (=for which) she loves his father. 她喜歡那個(gè)孩子因?yàn)樗龕?ài)著孩子的父親。

　　He didn’t like the way that (=in which = \) she speaks to his mother. 他不喜歡她對(duì)他的母親那樣說(shuō)話。

　　that和which在從句里都可以做賓語(yǔ)和主語(yǔ)，做賓語(yǔ)時(shí)可以省略。(The place which\that\不填I(lǐng)visited yesterday was boring.)在定語(yǔ)從句中,關(guān)系代詞在限制性定語(yǔ)從句中作賓語(yǔ)可以省略,不管是that，which，還是whom。但是which能引導(dǎo)非限制性定語(yǔ)從句，that則不行。

　　只能用that的幾種情況：

　　1. 當(dāng)先行詞為all, much, little, none及由any, every, some, no所構(gòu)成的復(fù)合不定代詞時(shí)。

　　如：We should do all that is useful to the people. 我們應(yīng)該做一切有益于人民的事情。

　　Please tell me anything that you know about the matter. 有關(guān)此事，凡是你所知道的請(qǐng)告訴我。

　　2. 當(dāng)先行詞被any, few, little, no, all, much, some等詞修飾時(shí)。 如：You can take any seat that is free. 任何空著的座位你都可以坐。 There is little work that is fit for you. 幾乎沒(méi)有適合你的工作。 3. 當(dāng)先行詞為序數(shù)詞或被序數(shù)詞所修飾時(shí)。

　　如：When people talk about the cities of China, the first that comes to my mind is Beijing. 人們談?wù)撈鹬袊?guó)的城市的時(shí)候，我首先想到的是北京。

　　This is the fourth film that has been shown in our school this term. 這是我們校本學(xué)期放映的第四部電影。

　　4. 當(dāng)先行詞為形容詞最高級(jí)或被形容詞最高級(jí)修飾時(shí)(the best , the most等) 如：The best that I could do was to apologize. 我唯一能做的就是賠禮道歉了。 This is the most interesting story book that I have ever read. 這是我讀過(guò)的一本最有趣的故事書。

　　5. 當(dāng)先行詞被the very, the only, the last, the just, the same等修飾時(shí)。 如： This is the very book that I’m looking for. 這正是我在找的書。

　　The only thing that we could do was to wait. 我們唯一能做的事就是等待。 注意：先行詞被the same修飾時(shí)，關(guān)系代詞也可用as。如：I need the same book that / as you have. 我需要有你一樣的書。 6. 當(dāng)先行詞既包含人又包含物時(shí)。

　　如： They are talking of the heroines and their deeds that interest them. 他們正在談?wù)撍麄兏信d趣的女英雄及她們的事跡。

　　7. 當(dāng)先行詞是疑問(wèn)代詞who，which，what或主句以這些詞開頭時(shí)。

　　如：Who that has ever worked together with him doesn’t admire him? 曾經(jīng)和他一起工作過(guò)的誰(shuí)不欽佩他?

　　Which is the star that is nearer to the earth? 哪個(gè)是離地球比較近的星星? 8. 當(dāng)先行詞為主句表語(yǔ)或關(guān)系代詞為從句表語(yǔ)時(shí)。

　　如：That’s a good book that will help you a lot. 那是本對(duì)你很有幫助的書。 Our school is no longer the place that it used to be. 我們的學(xué)?，F(xiàn)在已不是過(guò)去的那個(gè)樣子了。

　　9. 先行詞為time時(shí)，當(dāng)time表示次數(shù)，引導(dǎo)詞用that, 可省略。 當(dāng)表示時(shí)間，可用that或when引導(dǎo)，都可省略。 如：I do remember the first time(that) I had ever heard the sweetest voice in the world.我很清楚地記得當(dāng)我第一次聽(tīng)到世界上最美的聲音的時(shí)候。 I did't remember the exact time (when/that) I arrived in Shanghai last month. 我不記得上個(gè)月到達(dá)上海的確切時(shí)間了。

　　10.在固定結(jié)構(gòu)the same...that...; so...that...; such...that...以及it is/was...that...的強(qiáng)調(diào)句型中,須用that。如： This is the same museum that you once visited.
