11. On his birthday he received a mysterious present __wrapped______ in gold paper.

A. wrapped B. to wrap C. wrapping D. wrap

这里是用过去分词来作表语，形容这个present

12. ––That woman has been taking care of the two white tigers for 8 years.

13. Mr. Smith, __tired______ of the ___boring_____ speech, started to read a novel.

A. tired; boring B. tiring; bored C. tired; bored D. tiring; boring

tired在这里是习惯用语，tired of doing sth，所以不能用tiring；boring是speech的形容词；bored是只能形容人的“无聊的”，比如，he is bored.

14. –– Bob, You __should______ have posted those letters.

–– Sorry. I forgot it.

A. can B. should C. must D. may

这里是“应该要干什么”的意思，言下之意是没有干

15. A driver must keep his safety belt __fastened____ while driving.

A. fastening B. fasten C. fastened D. to fasten

fasten是动词“系紧”的意思，这里用过去分词来作表语

16. If we __had known______ your telephone number, we would have called you yesterday.

A. have known B. had known C. knew D. know

这里同样是虚拟语气，也就是“如果我们昨天知道他的**的话”，言下之意不知道

A. must B. should C. need D. might

同上题，只不过这里用的是猜测的语气

这里是说将来的事，而且是他已经打算好了的，所以用will而不是would

20. ––What did you see at the fireworks display?

––I saw many __excited______ people. They were _astonished_______ at the beauty of the fireworks.

A. exciting; astonishing B. excited; astonished C. excited; astonishing D. exciting; astonished

这里考的是ing形式和过去分词来作表语。一般来说，ing形式是形容本人/本物品的；而-ed是形容人“被...”

比如原句中，excited people是“被激动的人们” ，而exciting people 是“有趣的人们”

21. The listening text might be easier for the students if you get it __divided______ into two parts.

A. dividing B. to divide C. divided D. divide

同理，这里是用动词的过去分词来作表语

22. Don’t leave the water __running______ while you brush your teeth.

A. being run B. running C. run D. to run

leave the water running是英语固定用法，是“开着水龙头让水一直哗哗流的意思”

23. E-shopping, when properly __done______, can save us a lot of time and money.

A. doing B. to do C. having done D. done

你要看出来哦，这里是句子的省略说法，原句是"E-shopping, when it is properly done"

24. __Given______ more time and attention, we can do it much better.

A. Given B. To give C. Giving D. Having given

这里也是省略的虚拟说法，意思是“如果给我们更多时间的话”

25. I feel sick. I wish I __hadn't eaten______ so much cake.

A. don’t eat B. didn’t eat C. haven’t eaten D. hadn’t eaten

如上，同样是虚拟语气，所以用过去式

语法问题

when i had been fastening my seat belt the plane had been taking off.

你的这个句子是错误的。

When I was fastening my seat belt, the plane took off.这是正确的。

原因：两者是同时发生的事情，但是飞机起飞是瞬时动作，不能用进行时；

have+been+doing sth这种形式表示的意思是从过去到现在一直在做某事，到现在还在做的意思，你用在句子中就成了“我一直在系安全带，飞机一直在起飞”，就不对了。

明白了？
