1) 定語(yǔ)從句有限制性和非限制性?xún)煞N。限制性定語(yǔ)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(yǔ)從句是先行詞的附加說(shuō)明,去掉了也不會(huì)影響主句的意思,它與主句之間通常用逗號(hào)分開(kāi),例如: This is the house that we bought last month. 這是我們上個(gè)月買(mǎi)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(gè)月買(mǎi)的。(非限制性) 2) 當(dāng)先行詞是專(zhuān)有名詞或物主代詞和指示代詞所修飾時(shí),其后的定語(yǔ)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(jīng)是我的老師。 My house, which I bought last year, has got a lovely garden. 我去年買(mǎi)的的那幢房子帶著個(gè)漂亮的花園。 This novel, which I have read three times, is very touching. 這本小說(shuō)很動(dòng)人,我已經(jīng)讀了三遍。 3) 非限制性定語(yǔ)從句還能將整個(gè)主句作為先行詞, 對(duì)其進(jìn)行修飾, 這時(shí)從句謂語(yǔ)動(dòng)詞要用第三人稱(chēng)單數(shù),例如: He seems not to have grasped what I meant, which greatly upsets me. 他似乎沒(méi)抓住我的意思,這使我心煩。 Liquid water changes to vapor, which is called evaporation. 液態(tài)水變?yōu)檎羝@就叫做蒸發(fā)。 說(shuō)明:關(guān)系代詞that和關(guān)系副詞why不能引導(dǎo)非限制性定語(yǔ)從句。 ? |
