英语which的用法 1、在后置的非限制性定语从句中代替上文出现的事物或者情况(单数或复数). 2、在问句中作疑问代词,在名词从句中作为连接代词用,其含义为“哪儿,哪些”. 3、如果非限制性定语从句的先行词不是指主句内容,而是指详细的人、时间、地点,那么不用which. 这里主要讲解一下再定语从句中的用法： Here is the pen that/which you lost yesterday(that/which 指物作宾语) A plane is machine that/which can fly(that/which指物,做主语) He is the most careful boy that I know(that指人,作宾语) The man that works in this room is a chemist(that 指人,作主语) wheat is a plant that/which is grown in the north of China. 1、只能用that的情况： a、先行词为all、everything、nothing、anything、little等不定代词(something后也可以用which)： Is there anything (that) I can do for you town? That is all (that) I Know. b、先行词被序数词所修饰时： The first thing (that) we should do is to work out a plan. c、先行词被形容词最高级所修饰时： This is one of the most exciting football games(that)I have ever seen. The nanjing yangtse river bridge is the longest bridge (that) they ever seen. d、先行词被形容词最高级修饰时： This is the only thing (that) we can do now. He gave me the same pen (that) were written by Lu Xun? This is the very books that were e、领先行词中即有人又有物时： The man and the car (that)you want to see are all here .你想见的人和车斗在这. f、that 可指人,which那么不能. who is the man that is reading new paper over there? g、 在“the time when”等构造和某些事件状语中,when常被that代替,而且that往往被省略. I may leave here any time I want to. During the time I was there I visited him twice. h、 way 后面可根由that引导的定语从句,但that一般都省略： That was the way she looked after us. This is the question about which we’ve had so much discussion 但是,如果把介词放在从句后部.这时which 就可换为that并常省略,如上例可以改为： This is the question that we are had so much discussion about. All the books there,which have beautiful pictures in them,were written by him. 这个地方注意一下：引导词和先行词 引导词：就是引导从句的词,比方whether,how,what ,why,when等具有引导其后从句功能呢过得词. 先行词：定语从句的引导词前面的被定语从句所修饰的名词、代词.在定语从句中充当一定的成分. 本文来源：https://www.wddqw.com/doc/72eb1fcc350cba1aa8114431b90d6c85ec3a88e5.html
