in which, for which, on which, at which的不同用法 1)这些都是定语从句里面，由which引导的定语从句，介词提前。下面这些介词的使用除了意思上的区别，具体是要以which引导的从句而定的。 ①in which可以翻译成在……里面 The school (that/which) he once studied in is very famous. = The school in which he once studied is very famous. ②for which可以翻译成为了……目的 Tomorrow I will bring here a magazine (that/which) you asked for. = Tomorrow I will bring here a magazine for which you asked. ③on which可以翻译成在……的上面，或具体时间的某一天 I have a dresser in my bedroom, which there are many cosmetics on. = I have a dresser in my bedroom on which there are many cosmetics. ④at which可以翻译成在……里面或在…… The dumpling House which he often has dumplings at is very popular. = The dumpling House is very popular, at which he often has dumplings. 2)当然第一点只是介词作为基本意思的用法，还有一些固定搭配，得具体情况具体分析。 ①The plane may be several hours late, in which case there’s no point in our waiting. (固定搭配：in the case) ②The speaker paused to examine his notes, at which point a loud crash was heard. (固定搭配：at the point) ③Ten years of hard work changed her greatly, for which reason he could hardly recognize her at first sight. (固定搭配：for the reason) ④The film at which I fell asleep was very boring. (Here "at which" is based on "fell asleep at the film"因为电影无聊而睡觉。) ⑤The little creature in which scientists are interested is known as ET. (这里"be interested in"是词组原因) ⑥This is the book for which he is looking. (即等于This is the book which he is looking for，这主要是因为look for 这一短语) |
