大学英语四级语法精要:虚拟语气-时间条件句

时间条件句

if he had received six more votes, he would be our chairman now.
if we hadn’t got everything ready by now, we should be having a terrible time tomorrow.

有时假设的情况并不以条件从句表示, 而是通过一个介词短语来表示.

without music, the world would be a dull place.
we could have done better under more favorable conditions.
that would have been considered miraculous in the past.
but for the storm, we should have arrived earlier.

如果条件句从句中包含有 were, had, should 或could, 有时可把if省略掉, 并把were, had, should或could放在主语前面.

had we made adequate preparation, we might have succeeded.
should there be a flood, what should we do?
were it not for their assistance, we would be in serious difficulty.
