1.The minister of Finance is believed ___ of imposing new taxes to raise extra revenue.
A.that he is thinking B.to be thinking
C.that he is to think D.to think
这句话是believe的被动语态的用法,在主动语态中常用这样一种结构：believe sb./sth. to be/ to be doing/ to have been而不跟to do
变成被动语态sb.is/was believed to be thnking of而不能跟to think
汉语应该译为：
人们认为财政部长一直在考虑征收新的税来增加额外的税收.
2.It is not uncommon for there ___ problems of communication between the old and the young.
A.being B.would be C.be D.to be
这句话中的It是形式主语,真正的主语是for there to be problems of communication between the old and the young.这个结构实际上就是：for sb. to do sth.这是一个带有逻辑主语的动词不定式短语for sb. 是动词不定式to do sth.的逻辑主语.在本句中的for there就是动词不定式 to be problems of communication between the old and the young的逻辑主语,我们用它来取代It,就得到这样一个句子：
For there to be problems of communication between the old and the young is not uncommon
there being可以被看成是there be句型的动名词短语,或there be句型的分词的独立主格结构在此不能用
汉语应该译为：老人和年轻人之间存在沟通问题不是不寻常的/是常见的.
3.I have no objection ___ your story again.
A.to hear B.to having heard C.to hearing D.to have heard
have no objection to是固定结构,这里的to是介词,因此只能跟动名词
选项B. to having heard时态错误
汉语应该译为：我不反对再听一次你的故事.
4.I tried to relax because I knew I would use up my oxygen sooner
____.
A.the more exciting I got B.I got excited more
C.and more I got excited D.and I got more excited
这句话的答案A需要改一下,改成：A.the more excited I got
用exciting是错误的.
本句是the more... the more 的结构
可以把这句话重新整理为：
I tried to relax because I knew the more excited I got the sooner I would use up my oxygen.
汉语应该译为：
我尽量放松,因为我知道,我越兴奋,我就会越快把氧气用完.
