A. find B. to find C. on

finding D. in finding

解析：本题考insist的用法和非谓语动词。“insist”当“坚持（认为该怎样做）”解时，

后接虚拟语气的从句或接on doing。

答案: C

26. More patients ___________ in hospital this year than last year.

A. treated B. have treated C. had been treated D. have been treated

解析：本题考时态语态，句中treat与patient连用，应是“治疗”的意思，故全句意为：

今年到医院就医的病人比去年多。病人应被治疗，故需被动语态，且是今年（现在）的事，

故选D，现在完成时的被动语态。

答案: D

27. Tom owns _______larger collection of _______ books than any other student in

our class.

A. the; 不填

不填; the

解析：考冠词。collection是可数名词，须填冠词，被比较级修饰，但是大范围的比较，

故填不定冠词。后一空是泛指的表类别的书，且已用了复数，不填冠词。故选B。

答案: B

28. -- You haven't lost the ticket, have you?

-- _________. I know it's not easy to get another one at the moment.

A. I hope not B. Yes, I have C. I hope so D. Yes, I’m afraid

so

解析：本题考交际用语、语境和省略。本题B、D两项以yes开头，那就表示已经把票丢

了，与后文内容不相符，不能只说再弄票不容易，而应表示着急或遗憾才对。C项用于前句

是肯定句的时候，此处若用，意思就是：我希望如此（＝我希望我已经把票丢了），显然不

合理，A项中的not一词替代一个与上文相同的否定句，合乎语境。

答案: A

29. It's ten years since the scientist _______on his life's work of discovering the

valuable chemical.

A. made for B. set out

B. a; 不填 C. a; the D. C. took off D.
