标题 | 定语从句中关系词的选择 |
范文 | 董晨 定语从句是用来修饰主句中某一名词或代词的从句。它一般都跟在所修饰的名词或代词的后面,被定语从句修饰的名词或代词称为先行词,引导定语从句的词叫关系词。 关系词的选择取决于先行词在从句中所作的成分,若先行词在从句中作主语、宾语或定语,则选择关系代词;若先行词在从句中作状语,则选择关系副词。 一、关系代词的选择 1. Tom is a boy who (that) studies hard. 指人,作主语 2. Jane is a girl whom (that) you can trust. 指人,作trust的宾语 3. Bob is the boy whose father is a pilot. 指人,作定语 4. A plane is a machine which (that) can fly. 指物,作主語 5. Is this the book which (that) you bought yesterday? 指物,作宾语 6. My uncle bought a house, whose roof (=the roof of which) was green. 指物,作定语 注意: 1. 若先行词在从句中作宾语时,关系代词可以省略。如例2和例5两句中的关系代词都可以省略。 2. 一般说来,无论先行词是指人还是指物,也不论代表先行词的关系代词在从句中作主语还是作宾语,都可以用that,但需注意的是,that还有“六用,三不用”原则。 六用 (1)当先行词是指事物的anything, everything, nothing, none, all, few, little, much等不定代词,或先行词被any, every, no, all, few, little, much修饰的事物名词时,多用that。如: I cannot learn anything that does not interest me. Ive read all the books that were borrowed from the library. (2)当先行词被the only, the very, the same, the right/just, one of等修饰时,多用that。如: This is the very book that I am looking for. This is the only watch that I have. (3)当先行词既有人又有物时,宜用that。如: They talked about the persons and the things that they remembered in the school. (4)当先行词为序数词或先行词被序数词修饰时,多用that。如: It was the first skyscraper that was designed by our own engineers. (5)当先行词为形容词最高级或先行词被形容词最高级修饰时,多用that。如: Shakespeare is the greatest English writer that ever lived. (6)当主句是以who 或which 开头的特殊疑问句时,为避免重复,多用that。如: Who is the lady that is talking to our teacher? Which is the house that caught fire last night? 注意:一个句子中含有两个定语从句,一个关系代词用that,另一个用which。如: Let me show you the book that I borrowed from the library which was newly open to us. 三不用 (1)先行词是指人的one, anyone, everyone, those, people, he等,或指人的先行词位于there be之后时,用who 或whom,不用that。如: He who laughs last laughs best. God helps those who help themselves. One who has travelled far and wide will probably have a broad outlook. We should forgive people who hurt us. Is there anybody else who should be invited? (2)直接位于介词之后, 用which或whom,不能用that。如: Here is the car about which I told you. Who is the man with whom you just shook hands? (3)在非限制性定语从句中,用who, whom, which,不能用that。如: I have lost my pen, which I like very much. 二、关系副词的选择 1. 当先行词是表示时间的名词,且在定语从句中作时间状语时,用when。如: October 1st,1949 was the day when the Peoples Republic of China was founded. 注意:有时虽然先行词是表示时间的名词,但如果定语从句中缺少的是主语或宾语,此时应使用关系代词。请比较: I will never forget the days when I worked in the city. 先行词 作时间状语 I will never forget the days (that /which) I spent in the city. 先行词 作宾语 2. 当先行词是表示地点的名词,且在定语从句中作地点状语时,用where。如: Everyone wants to visit the place where Lu Xun once lived. 注意:where 和when 一样,在定语从句中只能充当状语;否则,必须用关系代词。请比较: This is the factory where my father worked last year. 先行词 作地点状语 This is the factory (that /which) my father visited last year. 先行詞 作宾语 3. 当先行词为reason,且在定语从句中作原因状语时,用why。如: The reason why she told a lie is unknown. 注意:当在句中不是作状语,而是作主语或宾语时,用that。请比较: The reason why he was late for class is that he got up late. 先行词 作原因状语 The reason that/which he gave us was hard to accept. 先行词 作宾语 即学即练: 1. This is the school __________we visited yesterday. 2. This is the school ____________ my father works. 3. The boy ______ parents are dead was brought up by his grandfather. 4. Can you see the house of______ the window face the south? 5. This is the very thing _______ I am looking for. 6. Who is the man _______ spoke to you at the gate? 7. I believe the reason ___________he likes traveling. 8. I believe the reason ___________he gave me for his decision. 9. The way _______ he explained to us was very simple. 10. The way _______ he explained the sentence to us was very simple. 参考答案:1. that / which 2. where / in which 3. whose 4. which 5. that 6. that 7. why / for which 8. that / which 9. that / which 10. that /in which |
