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。

　　Ⅰ.单项填空

　　1．It has been that some government leaders ________ their authority and position to get illegal profits for themselves that resulted in the opposition in Thailand.

　　A．abuse　B．take

　　C．employ

　　D．overlook
