虚拟语气 动词形式练习 求助

Question

1,The doctor advised him____(give) up drinking.
2,It _____(suggest) at the meeting that an exception ___(make).
3,He suggested___ (set) up a committee to investigate the matter.
4,It was believed right that the criminal____(sentence) to death.

6,Do you agree to the suggestion that the war prisoners ___(set) free.
7,He insisted on___(know) where you had put his keys.
8,His requirement was that every student_____(preview) before class.
上面的我觉得应该都是涉及到虚拟语气的。所以主语我全部是should 加动词原形，从句用现在时或者过去时，但是答案不是这样的
1 ,to give 为什么是动词不定式
2, was suggest should be made . 为什么不是is , be made 而不是 make
3 setting 也不是动词原形 是动名词吧，不懂为什么用动名词。
4 should be sentenced 用 be sentenced 而不是 sentenced
5 should be set 用 be set 而不是set
7 knowing 不懂

Answer 1

1. advise sb to do sth 建议某人做某事。2.应该是was suggested， （should）be made.前面表示被动语态，后面是虚拟语气加被动语态。3.suggest doing表示建议做某事；4.要用被动式的，因为判某人死刑也就是某人被判死刑啊be sentenced to death.5.it is/was + adj. +that也要用虚拟语气哦6.还是虚拟语气的用法加被动式。set sb. free。7.insist on/upon doing. 因为on 是介词啊，所以要用动名词的。8.用preview。因为前面的requirement。表示需要建议命令的词语（动词或名词）都要用虚拟语气哦。
明白了吗？加油哦！
