英語定語從句關系詞的用法與區(qū)別定語從句即指在主從復合句用作定語的從句。定語從句通常修飾名詞或代詞,對它進行限制、描繪和說明。受定語從句修飾的詞語叫先行詞,引導定語從句的詞語叫關系詞。關系詞按其性質(zhì)又分關系代詞和關系副詞。關系詞不僅引導定語從句,同時還在定語從句充當一定的句子成分。
一、關系詞的用法特點關系詞分關系代詞和關系副詞。關系代詞主要有 that, who, whom, whose, which, as 等,其中who等,其中whowhom 只用于指人,which和as 只用于指事物,whose和 that既可于指人也可用于指物,它們在定語從句可用作主語、賓語、表語或定語;關系副詞主要有when, where 和why,其中when表示時間,whenwhere表地點,why表原因,它們在定語從句中均用作狀語:The dog which [that] was lost has been found. 丟失的狗找到了。(which / that指物,在從句中用作主語)I have forgotten everything that I learnt at school. 我把學校學的所有東西都給忘了。(that指物,在從句中句作賓語(that)The man who lives in that house is my uncle. 住在那座房子里的人是我叔叔。(who指人,在從句中作主語)It was an island whose name I have forgotten. 這是一座島,名字我忘了。There are some students whose questions I can’t answer. 有些學生提出的問題我回答不了。(whose指人,在從句中作定語)
二、關系詞的選擇選擇關系詞可考慮以下四點:(1) 一看先行詞的意義,即分清先行詞是指人、指物、時間、地點還是原因(如指物時不能用who或whowhom,指人時通常不用which等)。(2) 二看關系詞的句法功能,即分清關系詞是擔任什么句子成分,是作主語還是賓語、是作定語還是狀語等(如作定語通常用whose,有時也用which;作狀語要用when, where, why);作狀語要。(3) 三看定語從句的種類,即分清是限制性定語從句還是非限制性定語從句(如that和why通常不引導非限制性定語從句)。(4) 四看文體,即分清是正式文體還是非正式文體,是書面語體還是口語體。(4)
三、兩組關系詞的用法區(qū)別1. that 與 which的用法區(qū)別兩者都可指物,有時可互換。其區(qū)別主要在于:(1) 引導非限制性定語從句時,通常只用which:He drove too fast, which was dangerous. 他開車很快,這是很危險的。(2) 直接放在介詞后作賓語時,通常只用which: whichThe tool with which he is working is called a hammer. 他干活用的那個工具叫做錘子。(3) 當先行詞是much, little, none, all, few, every(thing), any(thing), no(thing) 等不定代詞或受其修飾時,通常用that:All [Everything] that can be done must be done. 凡能做的事都必須做。(4) 當先行詞受the very, the only, the same 等修飾時,通常用that:This is the only example that I know. 我知道的例子只有這一個。Those are the very words that he used. 那是他的原話。(5) 當先行詞有形容詞最高級或序數(shù)詞(包括last, next等)等修飾時,通常用that:This is the best dictionary that I’ve ever used. 這是我用過的最好的詞典。The first thing that you should do is to work out a plan. 你應該做的第一件事是訂個計劃。(6) 當關系代詞在定語從句中用作表語時,通常用that:China is not the country (that) it was. 中國已不是過去的樣子了。(7) 當先行詞是一個既指人又指物的并列詞組時,通常用(7) that:They talked about the persons and things that most impressed them. 他們談論了使他們印象最深的人和事。(8) 當要避免重復時:Which is the course that we are to take? 我們選哪門課程?2. that與who的用法區(qū)別(1) 兩者均可指人,有時可互換:All that [who] heard him were delighted. 所有聽了他講話的人都很高興。Have you met anybody that [who] has been to Paris? 你遇見過到過巴黎的人嗎?He is the only one among us that [who] knows Russian. 他是我們中間惟一懂俄語的人。(2) 但是在下列情況,通常要用 that:①當先行詞是一個既指人又指物的并列詞組時:I made a speech on the men and things that I had seen abroad. 我就我在國外所見到的人和事作了報告。②當先行詞是who時(為避免重復):Who that has sympathy can laugh on that occasion? 有同情心的人誰會在那個時候發(fā)笑呢?③當關系代詞在定語從句中作表語時(可省略):Tom is not the boy (that) he was. 湯姆這孩子已不是以前那個樣子了。
