限制性與非限制性定語從句四大區(qū)別
限制性定語從句和非限制性定語從句有四大區(qū)別,現(xiàn)作簡要介紹。
一、在句中作用不同
限制性定語從句對被修飾的先行詞有限定制約作用,使該詞的含義更具體,更明確。限制性定語從句不能被省略,否則句意就不完整。
非限制性定語從句與先行詞關(guān)系不十分密切,只是對其作一些附加說明,不起限定制約作用。如果將非限制性定語從句省去,主句的意義仍然完整。
二、外在表現(xiàn)形式不同
限制性定語從句因與先行詞關(guān)系密切,所以不可以用逗號將其與主句隔開;而非限制性定語從句與先行詞關(guān)系不十分密切,所以可用逗號將其與主句隔開。
例 1. Do you remember the girl who taught us English?
你還記得教我們英語的那個(gè)女孩嗎?
例 2. Clock is a kind of instrument which can tell people time.
鐘是一種能夠告訴人們時(shí)間的儀器。
例 3. This is the place where he used to live.
這就是他過去居住的地方。
例 4. Mr. Zhang, who came to see me yesterday, is an old friend of mine.
張先生昨天來看我,他是我的一位朋友。
例 5. We walked down the village street, where they were having market day.
我們沿著村里的大街向前走去,村民們正在那里趕集。
析:在前三個(gè)例句中,定語從句與先行詞關(guān)系密切,為限制性定語從句,不可用逗號將其與主句隔開。在后兩個(gè)例句中,定語從句與先行詞關(guān)系不密切,為非限制性定語從句,可用逗號將其與主句隔開。
三、先行詞內(nèi)容有所不同
大多數(shù)限制性和非限制性定語從句的先行詞往往為某一個(gè)詞或短語,而特殊情況下非限制性定語從句的先行詞也可為整個(gè)主句,此時(shí)非限制性定語從句常由 which 引導(dǎo)。
例 1. A middle-aged woman killed her husband, which frightened me very much.
一個(gè)中年女子殺害了自己的丈夫,這令我十分恐懼。
析:由語境可知,令“我”恐懼的內(nèi)容應(yīng)為“中年女子殺害了自己的丈夫”這整個(gè)一件事,因此先行詞為整個(gè)主句,此時(shí)應(yīng)由 which 引導(dǎo)定語從句。
例 2. A five-year-old boy can speak two foreign languages, which surprises all the people present.
一個(gè)五歲男孩會(huì)講兩門外語,這令所有在場的人感到非常驚訝。
析:由語境可知,令所有在場的人感到驚訝的內(nèi)容是“一個(gè)五歲男孩會(huì)講兩門外語”這整個(gè)一件事,因此先行詞為整個(gè)主句,此時(shí)應(yīng)由 which 引導(dǎo)非限制性定語從句。
四、關(guān)系詞的使用情況有所不同
(一) that 不可用于引導(dǎo)非限制性定語從句
所有關(guān)系代詞和關(guān)系副詞均可引導(dǎo)限制性定語從句,大多數(shù)關(guān)系代詞和關(guān)系副詞可引導(dǎo)非限制性定語從句,但 that 不可。
例 1. 他送給他母親一臺彩電作為生日禮物,這使她非常高興。
誤: He gave his mother a color TV set for her birthday, that pleased her a lot.
正: He gave his mother a color TV set for her birthday, which pleased her a lot.
例 2. 他沒通過這次考試,令我很失望。
誤: He didn't pass the exam, that disappointed me.
正: He didn't pass the exam, which disappointed me.
值得注意的是,不少同學(xué)誤認(rèn)為只有 which 才能引導(dǎo)非限制性定語從句,這個(gè)觀點(diǎn)是不正確的。使用非限制性定語從句時(shí),如果先行詞指人,則用 who , which 或 whose 引導(dǎo)非限制性定語從句;先行詞指物可用 which 引導(dǎo)非限制性定語從句;先行詞表時(shí)間或地點(diǎn)且在從句中作時(shí)間狀語或地點(diǎn)狀語時(shí),可用 when , where 引導(dǎo)非限制性定語從句。
例 1. We'll graduate in July, when we will be free.
我們將于七月份畢業(yè),到那時(shí)我們就自由了。
例 2. Last Sunday they reached Nanjing, where a conference was to be held.
他們上周日到達(dá)南京,有個(gè)會(huì)議要在那里舉行。
(二)關(guān)系代詞替代情況不同
關(guān)系代詞 whom 在限制性定語從句中作賓語時(shí)可用 who 代替 whom ,但 whom 在非限制性定語從句中作賓語時(shí)不可用 who 來代替。
例 1. This is the girl whom I met in the street.
這是我在街上遇到的那個(gè)女孩。
析:先行詞 the girl 在限制性定語從句中作賓語,可用 who 代替 whom .
例 2. A young man had a new girl friend, whom he wanted to impress.
一個(gè)年輕的小伙子新交了一個(gè)女朋友,他想給她留下深刻的印象。
析:先行詞 a new girl friend 在非限制性定語從句中作賓語,不可用 who 代替 whom .
在限制性定語從句中,先行詞指人時(shí)可用 that 代替 who/ whom ,但在非限制性定語從句中先行詞指人時(shí),不可用 that 代替 who/whom .

誤: She has a sister, that is a teacher.
正: She has a sister, who is teacher.
(三)關(guān)系代詞省略情況不同
關(guān)系代詞在限制性定語從句中作賓語時(shí)可以省去,非限制性定語從句的所有關(guān)系詞均不可省。
例 1. This is the book (which/that) he lost yesterday.
這就是他昨天丟的那本書。
析:先行詞 the book 在限制性定語從句中作賓語,關(guān)系代詞 which 或 that 可以省略。
例 2. The book, which he lost yesterday, has been found.
他昨天丟了這本書,但現(xiàn)在已找到了。
析:先行詞 the book 在非限制性定語從句中作賓語,關(guān)系代詞 which 不可省。
