8.If we________the other road, we might have arrived here in time for the meeting.
A.take
B.had taken
C.took
D.have taken
答案 B [句意:如果我们走另一条路的话,我们或许能够及时到达这里参加这次会议了。根据主句的谓语动词might have arrived可以推出,本句是与过去事实相反的虚拟语气,所以if条件句中应该用过去完成时。]
9.Had I known about this computer program, a huge amount of time and energy________.
A.would have been saved
B. had been saved
C.will be saved
D. was saved
答案 A [句意:如果我知道这个电脑程序,就会节省大量的时间和精力。由“Had I known”可知,从句为与过去事实相反的虚拟条件句,省略了if。所以主句谓语形式应为 would have done。]
10.________the present economic crisis go on, the society would face a more troublesome situation.(2017·西安高二检测)
A.Would
B.Should
C.Might
D.Could
答案 B [句意:如果当前的经济危机继续下去,社会将面临更加困难的局面。根据主句中的would可以得知此处是对于将来时间进行的虚拟,从句用if十主语+should do sth,去掉if应把should提前,故选B项。]
