四. 不同關系詞的用法

　　1. 關系代詞which的用法

　　(口語) What is your favorite spare time activity?

　　I usually choose to relax myself by watching American TV series in my spare time, ___________________________________________________.

　　(口語) Do young people in your country live by themselves or with their parents?

　　As far as I know, many people of my age live with their parents not because they want to but because they have to. ______________________________________________

　　(口語) What leisure activities are popular in your country?

　　___________________________________________________

　　由which引導的非限制性定語從句，其先行詞對應的不僅可以是一個詞或短語，也可以是主句的一部分甚至一個完整的句子。而在限制性定語從句中which就絕對不能用于修飾一個句子。

　　例句：(口語) My brother is a book-worm, when deeply absorbed in his books, which

　　he often is, he will forget about everything.

　　(口語) I am quite an outgoing person, which my brother is not.

　　(閱讀) Fathers spend less time in housework and childcare, which is regarded by some scientists as a major contributor to the stress-related anxiety of employed

　　mothers.

　　(寫作) 要解決交通問題，我們首先要解決的第一個問題就是日益增加的私車數(shù)量，我認為這是造成交通問題的最主要原因。

　　To solve the traffic problem, ___________________________________________________

　　2. 由who/whom/whose引導的定語從句

　　用法：當關系代詞在定語從句中作主語時用who，作賓語，表語時用whom,表示所屬關系時用whose。 它們所引導的定語從句既可以是限制性定語從句也可以是非限制性定語從句。

　　(口語) Describe your idol.

　　My idol is Jay,________________________________________________________________.

　　My idol is Jay, ________________________________________________________________.

　　My idol is Jay, ________________________________________________________________.

　　(口語) Describe a person that you respect the most.

　　我的父親是一個教了30多年書的教師，他是我最尊敬的人。

　　___________________________________________________

　　(口語) (1) Rain is a Korean Singer. (2). I appreciate him very much. (3). His popularity is second to none in Asia.

　　___________________________________________________

　　3. 關系詞when的用法

　　When引導的定語從句通常用在表示時間的名詞或短語如time, year, day后面，它引導的定語從句既可以是限制性也可以是非限制性定語從句。

　　例句： (口語) Describe an important Chinese festival.

　　Spring Festival is the time when all the family members come back home and get together in China. (限制性定語從句)

　　In China, the most important traditional festival is Spring Festival, when all the family members would come back home and get together. (非限制性定語從句)

　　錯誤觀念：凡是先行詞是time/day等時間概念，關系詞就一定是when。

　　(1). 我永遠忘不了我第一次見到她的那一天。

　　I will never forget the day when I met her for the first time.

　　(2). 我永遠忘不了我在上海和她度過的那些日子。

　　I will never forget the days when I spent with her in Shanghai. (X)

　　練習： (口語) Describe a day that is special to you.
