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.
