定語從句例句及練習(xí)題

  由as, which 引導(dǎo)的非限定性定語從句,as和which可代整個(gè)主句,相當(dāng)于and this或and that.As一般放在句首,which在句中。例如:

  As we know, smoking is harmful to ones health. 如我們所知,吸煙有害健康。

  The sun heats the earth, which is very important to us. 太陽使地球暖起來,這對(duì)我們?nèi)祟惡苤匾?/p>

  典型例題

  1)Alice received an invitation from her boss, ___came as a surprise.

  A. it B. that C. which D. he

  答案C. 此為非限定性從句,不能用 that修飾,而用which.,it 和he 都使后句成為句子,兩個(gè)獨(dú)立的.句子不能單以逗號(hào)連接。況且選he句意不通。

  2)The weather turned out to be very good, ___ was more than we could expect.

  A. what B. which C. that D. it

  答案B.which可代替句子,用于非限定性定語從句,而what不可。That 不能用于非限定性定語從句,it不為連詞,使由逗號(hào)連接的兩個(gè)句子并在一起在英語語法上行不通。

  3)It rained hard yesterday, ____ prevented me from going to the park

  A. that B. which C. as D. it

  答案B. as 和which在引導(dǎo)非限制性定語從句時(shí),這兩個(gè)關(guān)系代詞都指主句所表達(dá)的整個(gè)意思,且在定語從句中都可以作主語和賓語。但不同之處主要有兩點(diǎn):
