定语从句(二)

1．限制性和非限制性定语从句

1) 定义： 限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开。

① This is the house which we bought last month. 这是我们上个月买的那幢房子。（限制性定语从句）

② The house, which we bought last month, is very nice. 这幢房子很漂亮，是我们上个月买的。（非限制性）

2) 用法：专有名词或物主代词和指示代词被从句所修饰时，其后面的定语从句通常是非限制性的。

① Charles Smith, who was my former teacher, retired last year. 查理•史密斯去年退休了，他曾经是我的老师。

② My house, which I bought last year, has got a lovely garden.　我去年买的的那幢房子带有一个漂亮的花园。

③ This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。

非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数。

① He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。

② Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。
