9.Without the help,we ________ the program in time and I ________ so happy now.
A.can’t finish;would not be
B.will not finish;would not have been
C.couldn’t have finished;wouldn’t have been
D.couldn’t have finished;would not be
解析:选D。without=but for,所以排除A和B项;本句后半部分的时间表示的是现在,不是对过去的虚拟,所以选D。
10.The millions of calculations involved,had they been done by hand,________all practical value by the time they were finished.
A.could lose
B.would have lost
C.might lose
D.ought to have lost
解析:选B。had they been done by hand实际上是虚拟条件句if they had been done by hand省去if的倒装形式,它表示对过去情况的假设。剩下部分为主句,主语为The millions of calculations,involved作其定语。表示对过去情况的虚拟,主句应用“情态动词+have done”形式。1.(2012·万宁模拟)The scientist was rewarded by the government for________ such a great contribution to the country.
A.make
B.making
Cbeing made
D.having made
for的后面要用动名词形式,在获奖前贡献已经做出了,所以要用其完成式。语意为:这位科学家因为为国家做出了巨大的贡献,得到了政府的奖励。
