經(jīng)典習(xí)題

　　1. A computer can only do ________ you have instructed it to do.

　　A. how B. after C. what D. when

　　解析：答案為C。本題考查的是名詞性從句作賓語的用法。此句的引導(dǎo)詞既作連詞又在賓語從句中充當(dāng)一成分，故what最合適。

　　2. —I drove to Zhuhai for the air show last week..

　　—Is that _________ you had a few days off ?

　　A. why B. when C. what D. where

　　解析：答案為A。此題考查的是從句的用法。根據(jù)題意“我上周開車去珠海看航空展去了�！毕旅嬉痪浣又鴨枺骸澳蔷褪悄銥槭裁措x開的原因嗎?”故用why引導(dǎo)表語從句表示原因。

　　3. I hate __________ when peope talk with their mouths full.

　　A. it B. that C. these D. them

　　解析：答案為A。本題考查的是形式賓語的用法。題意為“我討厭人們談話時嘴里塞滿東西”。該空白處沒有任何含義，而且已經(jīng)用了when連接該賓語從句，所以此處只填一個形式賓語it。

　　4.I think Father would like to know I’ve been up to so far, so I decide to send him a quick note.

　　A. which B. why C. what D. how

　　解析：答案為C。考查賓語從句連詞用法，由結(jié)構(gòu)sb. be up to sth.可知，應(yīng)選what作介詞to的賓語。

　　5. We cannot figure out quite a number of insects, birds, and animals are dying out.

　　A. that B. as C. why D. when

　　解析：答案為C。本題考查賓語從句知識，figure out為及物動詞，故此句為賓語從句，從句意得知連詞在從句中作原因狀語，故選why.

　　6.After Yang Liwei succeeded in circling the earth, our astronauts desire do is walk in space.

　　A. where B. what C. that D. how

　　解析：答案為B。此題句子為時間狀語從句，全主句的主語是由主語從句來充當(dāng)?shù)�，并且主語從句中不定式動詞do缺少賓語，故選what。
