1.The computer of this kind can work ______ than the one of that kind. 【 D 】

　　A. hundred of times faster

　　B. a hundred time faster

　　C. hundred times faster

　　D. hundreds of times faster

　　【答案解析】：表示“數(shù)百”、“數(shù)千”、“數(shù)百萬(wàn)”等不確切數(shù)目時(shí)，要用hundreds / thousands / millions of結(jié)構(gòu)表示。D中hundreds of times意思是“數(shù)百倍”。答案為D.

　　2.When I was young， my grandmother told me that the earth ______ round. 【 A 】

　　A. is

　　B. was

　　C. has been

　　D. had been

　　【答案解析】：the earth is round是客觀真理，所以不管句子其它部分用什么時(shí)態(tài)，這個(gè)句子都用一般現(xiàn)在時(shí)。

　　3.—Do you know Jack well?

　　—Certainly. We ______ friends since ten years ago. 【 D 】

　　A. were

　　B. have made

　　C. have become

　　D. have been

　　【答案解析】：根據(jù)句意可知應(yīng)該用完成時(shí)，所以A答案錯(cuò)誤。have been…表示狀態(tài)，可以和表示一段時(shí)間的短語(yǔ)連用。have made和have become都是瞬間動(dòng)詞，不能和表示一段時(shí)間的短語(yǔ)連用。

　　4.These hamburgers ______ nice， so they have all ______ out. 【 C 】

　　A. taste， sell

　　B. are tasted， sell

　　C. taste， been sold

　　D. are tasted， been sold

　　【答案解析】：taste是系動(dòng)詞，taste nice構(gòu)成系表結(jié)構(gòu)，不用被動(dòng)語(yǔ)態(tài)。但第二個(gè)空格處應(yīng)該用被動(dòng)語(yǔ)態(tài)，因?yàn)閔amburgers與sell out之間是被動(dòng)的關(guān)系。所以答案是C.

　　5.We now have ______ fast ways of traveling that this big ocean seems to have grown smaller. 【 B 】

　　A. so

　　B. such

　　C. so a

　　D. such a

　　【答案解析】：such可以修飾可數(shù)名詞單復(fù)數(shù)和不可數(shù)名詞，名詞前可以有形容詞作定語(yǔ)，其結(jié)構(gòu)是“such +a/an+形容詞+可數(shù)名詞單數(shù)”，“such+形容詞+可數(shù)名詞復(fù)數(shù)/不可數(shù)名詞”。

　　6.I do not wish to ______ your sincerity. 【 B 】

　　A. reflect

　　B. reflect on

　　C. reflect in
