第一题选C是因为睡觉的动作发生在看电视之中.
第二题这样选的原因是争论一直在发生,并没有说结束,所以要用现在完成进行时.
第三题是因为修饰序数词要用不定式.
第四题是因为这句话的中心词是名词water what 是来修饰名词,这是一个感叹句,而how是来修饰形容词或副词的.
第五题是因为cause+宾语+to do sth是一个固定结构,意思是导致--发生.
第六题是因为倍数是直接修饰名词的,不能加of.
第七题是因为这里的have不是有的意思,而是一个助动词,没有词意,这句是一个There be have 句型的变形,这里的to have been 就是这个句型中的be,如果用He 作主语,应是这样的
He doesn't seem to have any difficulty solving the problem.
第八题是因为 主句动作发生在从句之中,而. As多强调随着.
第九题是因为 这句的语意是强调我们有这样的希望.
第十题是因为little 是代替时间time.也就是what little of my spare time.

1. A为过去完成时,表示"过去的过去",即该动作发生在一个过去的动作之前.如:He had fallen asleep when his mother came back home.(在妈妈回家之前他已经睡着了). 而此题中"入睡"这一动作并非发生在"看电视"之前,因此不能选A.
2. 题中时间状语"for two hours"给了最好的提示,应该用现在完成时态或现在完成进行时.表示"已经(不停地)争论了两个小时了",排除C.
另外,committee当被看成是一个集体时,视为单数;当被看成组成它的各个成员时应视为复数.题中的代词"themselves"给出了明确的提示, committee 在此应视为复数,故而排除A和B.
