  定語從句


  定語從句像形容詞一樣起修飾作用,但位于所修飾的名詞之后。定語從句由關(guān)系代詞引導(dǎo),緊跟在它所修飾的成分后面。關(guān)系代詞 who,whom與 that修飾人,which與 that修飾東西。關(guān)系代詞指代從句的主語或賓語,同時又充當(dāng)連接詞,把從句和主句連接起來。請看例句:


  (1)關(guān)系代詞作從句的主語(who/which/that):


  The dog which/that is carrying the basket is mine.


  叼著籃子的那只狗是我的。


  He's the porter who/that carried my suitcase.


  他就是那個扛著我的衣箱的搬運工。


  (2)關(guān)系代詞作從句的賓語(whom/that/which):


  They're the windows which/that the children broke yesterday.


  這些就是孩子們昨天打碎的窗戶。


  She's the lady whom I served yesterday.


  她就是我昨天服務(wù)過的那位女士。

  定語從句中的省略


  當(dāng)關(guān)系代詞代表主語并且從句中的謂語動詞是(現(xiàn)在)進(jìn)行時態(tài)時,關(guān)系代詞及助動詞be均可省略。如果關(guān)系代詞在從句中代表賓語,則往往可以省略。此外,定語從句可用介詞結(jié)尾。

  語法 Grammar in use


  must, have to和 needn't


  這3個詞都表示必要性。在前面已對 must和 have to介紹過。


  must是情態(tài)助動詞,而have to是普通動詞,二者在肯定句中一般可以互換,表示不可逃避的義務(wù)或責(zé)任。must更帶有說話人的主觀色彩,而have to則更強調(diào)客觀要求和外界影響。


  must一般只能表達(dá)現(xiàn)在的必要性,而have to則可以表達(dá)過去或?qū)淼谋匾。對比例句?/p>

  Must you go now?


  你必須現(xiàn)在就走嗎?


  Yes,I have to leave at once.

  I shall have to leave London tomorrow.


  我明早得離開倫敦。


  I had to stop smoking because it was forbidden in my company.


  因為我所在的公司內(nèi)禁止抽煙,所以我不得不停止了吸煙。


  如果我們用 must來提問,則只能用needn't來表達(dá)否定的回答。 needn't 還可以理解為have to的否定回答。needn't (don't need to)和 don't have to都表示不必要;而 mustn't卻表示絕對禁止,在說話人看來根本沒有選擇余地。請看例句:


  Must she leave early?


  她必須早走嗎?
