定语从句关系词的选择.docx

定语从句关系词的选择四关系词的选择 1 在非限制性定语从句中，关系代词作主语，只能用who 指人，which指物；关系代词做宾语，常用whom指人，which指物，它们都不能用that代替。 2关系代词作介词宾语，不论是在限制性定语从句中，还是在非限制性定语从句中，当介词前置时，只能用whom指人，which指物；但如果介词后置，则不受这种限制，关系代词还可以省去，特别是在口语中。如： Do you know the boy to whom she was talking? Do you know the boy (that) she was talking to? The pencil (which/that) he was writing with suddenly broke. 3在限制性定语从句中，当先行词指物时，关系词可用which或that，二者常可以互换；但在下列情况中，只能用that，不用which： (1) 当先行词是all, a lot, (a) little, few, much, none, anything, something, everything, nothing等词时。如： All that can be done has been done. In this factory I saw little / much that was different from ours. (2) 当先行词被all, any no, much, little, few, every等限定词所修饰时。如： We heard clearly every word that he said. (3) 当先行词是序数词或被序数词所修饰时。如： The first thing that should be done is to get the tickets. When people talk about Hangzhou, the first that comes to mind is the West Lake. (4) 当先行词是形容词最高级或被形容词最高级所修饰，以及先行词被序数词和形容 词最高级同时修饰时，如： Is that the best that you can do? Thats the most expensive hotel that weve ever stayed in. This novel is the second best one that I have ever read. (5) 当先行词被 the very, the only, the next, the last等所修饰时。如： This is the very book that I want to find. (6) 当先行词为指人和指物的两个并列名词词组时。如： The guests spoke highly of the children and their performances that they saw at the Childrens Palace. She described in her compositions the people and places that impressed her most. (7) 当主句是以which开头的特殊疑问句时。如： Which is the car that killed the boy? 4. 在限制性定语从句中，当先行词指人时，关系词可用who(m)或that，二者常可互换。 但在下列情况中，用who(m)，而不用that： (1) 当先行词是one, ones, any, few, anyone, anybody, someone, somebody, everyone, everybody等词时。如： Is there anyone who can answer this question? He was among the few who managed to live through the enemy prison camp. 注：在非正式文体中可以说：Youre the one that knows where to go.) (2) 当先行词是he, they, those, people, person等词时。如： He who wants to catch fish just not mind getting wet. Those who are against the proposal put up your hands. 注：在固定结构的谚语或习语中，可用he that。如： He that promises too much means nothing. (3) 当先行词有较长的后置定语修饰时。如： Do you know the writer in blue with thick glasses who is speaking at the meeting? (4) 在分隔式定语从句中，若先行词指人，为了明确修饰关系，应当用who(m)。如： A new master will came tomorrow who will teach you German. Theres only one student in the school who/whom I wanted to see. I was the only person in my office who was invited. (5) 两个定语从句同时修饰一个指人的先行词，第二个定语从句常用who(m)来引导，如： She is the only girl I know who can play the guitar. 5.当先行词前有such, so, as时，关系词应当用as。如： A wise man seldom talks about such things as he doesnt understand. He spoke in such easy English as everybody could understand. At this time of the day, all buses and trolleys have to carry as many passengers as they can. It is so easy a book as every schoolboy can read. Lets discuss such things as we can talk of freely. 另需注意： This book is written in such easy English as beginners can understand. This book is written in such easy English that beginners can understand it.
