定语从句中,关系代词优选只能用which的几种情况.doc

定语从句中关系代词只能用 which 引导的几种情况 (1) 当关系词前面有介词时，指物常用 which. The prize for which he worked so hard was a new bike. He built a telescope through which he could study the skies. (2) 非限制性定语从句指物时，多用 which. Bamboo is hollow, which makes it light. He wrote an article, he computer.  which tells  us  about  t 如果先行词本身是 that 时，只用 which. This is that which he bought yesterday. which 还有一种特殊用法， 它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概 念。在这种从句中， which 可以作主语，也可以作宾语或表语，多数情况下意思是与 and this 相似，例如： He  succeeded  in  the  competition,  which made  his  parents  very  happy.
