18.非限制性定語從句
1) 定語從句有限制性和非限制性兩種。限制性定語從句是先行詞不可缺少的部分，去掉它主句意思往往不明確；非限制性定語從句是先行詞的附加說明，去掉了也不會影響主句的意思，它與主句之間通常用逗號分開，例如：
This is the house which_ we bought last month.
這是我們上個月買的那幢房子。（限制性）
The house, _which_ we bought last month, is very nice.
這幢房子很漂亮，是我們上個月買的。（非限制性）
2) 當先行詞是專有名詞或物主代詞和指示代詞所修飾時，其后的定語從句通常是非限制性的，例如：
Charles Smith, _who_ was my former teacher, retired last year. 查理•史密斯去年退休了，他曾經是我的老師。
My house,_which_ I bought last year, has got a lovely garden.我去年買的的那幢房子帶著個漂亮的花園。
This novel,_which_ I have read three times, is very touching. 這本小說很動人，我已經讀了三遍。
3) 非限制性定語從句還能將整個主句作為先行詞, 對其進行修飾, 這時從句謂語動詞要用第三人稱單數，例如：
He seems not to have grasped what I meant,which_ greatly upsets me. 他似乎沒抓住我的意思，這使我心煩。
Liquid water changes to vapor, _which is called evaporation. 液態水變為蒸汽，這就叫做蒸發。
說明：關系代詞that和關系副詞why不能引導非限制性定語從句。
