Unit 2 助动词、情态动词(三)


7. Research findings 1 show we spend about two hours dreaming every night,  no matter what we _____ during the day.
A. should have done
B. would have done
C. may have done
D. must have done


8. The boy spent as much time watching TV as he _____ studying.
A. does
B. had
C. was
D. did


答案:
7. C
译文:研究结果表明:我们每天晚上有两个小时在做梦,不管我们白天做了什么。
本句是情态动词的用法。“may+have+过去分词”的肯定形式表示对过去发生的情况进行推测。


8. D
译文:这个男孩花在看电视上的时间同用在学习上的时间一样多。
本句是助动词起替代作用的用法。这里用替代词did 代替前面句中的spent。替代词要与被替代词在时态、数和人称上保持一致,如果本句中前部分用的是spends, 则替代词就要用does.



n.发现物( finding的名词复数 );调查(或研究)的结果;(陪审团的)裁决
  • It behoves us to study these findings carefully. 我们理应认真研究这些发现。
  • Their findings have been widely disseminated . 他们的研究成果已经广为传播。
