主标题：专升本英语练习题及答案(3.30)

　　1.It ______ Mike and Mary who helped the old man several days ago.

　　A. was B. are C. were D. had been

　　【答案】A。解析：本题考查的是强调句式。强调句式由“It is/was + 被强调成分+that/who…”构成。由于句中的动作是发生在过去，故选A。

　　2.If you don’t go, neither ______.

　　A. shall I B. do I C. I do D. I shall

　　【答案】A。解析：本题考查的是倒装句。句意是：如果你不去，那么我也不去。Neither位于句首，句子部分倒装，排除C和D选项。而这是对将来事情的阐述，所以选择A选项。

　　3.There is no doubt ________ Catherine is fond of dancing, for she always practices it on weekends.

　　A. whether B. if C. that D. which

　　【答案】C。解析：考查同位语从句，句意：毫无疑问Catherine喜欢跳舞，因为她总是在周末练舞。分析句子的结构可知，逗号之后为“for”引导的原因状语从句，逗号之前是主句，主句中结构为"There is no doubt that…"意为"毫无疑问…"，连词"that"引导同位语从句解释说明名词"doubt"的具体内容，同位语从句中句子结构和意思已完整，"that"无意义也不充当成分，只起连接词的作用.故C为正确答案。

　　4.You have seen the girl ________ sister is a Chinese teacher.

　　A. whom B. of whom C. whose D. of which

　　【答案】C。解析：此句先行词为the girl，定语从句为sister is a Chinese teacher，二者构成的完整句为The girl’s sister is a Chinese teacher.先行词的’s所有格构成的所属关系结构在从句中作定语。故选C。

　　5.He found it increasingly difficult to read, ______ his eyesight was beginning to fail.

　　A. and B. for C. but D. or

　　【答案】B。解析：此题考查原因状语从句。“his eyesight was beginning to fail”是“he found it increasingly difficult to read”的原因，因此本题应选用可以表示原因的连词for引导原因状语从句。故选B。

　　6.He has never ridden a horse before, ______?

　　A. does he B. has he C. hasn’t he D. doesn’t he

　　【答案】B。此题考察反义疑问句，前面有否定词，所以后面要用肯定形式提问。前面是完成时态，所以提问要用has，故选B。
