请说明原因,
1.Sorry,I am too busy now.If I __have/had__ time,I would certainly go for an outing with you.
2.Food supplies in the flood-stricken area _______.We must act immediately before there ' s none left.
A.have run out B.are running out C.have been run out D.are being run out
第一题选 had.句意是:抱歉,我现在很忙.假如我有时间,我定会跟你出去.这句是虚拟语气,从句用过去时,主句用过去将来.再举个例子:If I were her,I would not go out with him.(如果我是她,我就不会跟他出去.[其中含义还有这是你自己的见解和建议.])
第二题选B.句意是:洪涝重灾区的食品供很快告罄.我们必须马上在(食品供应)一无所剩前采取行动.也就是说食品供应快完竭了,用 be (is/are) running out 的形式表达.A 选项表示已经没有;C选项是已经没有的被动式;D选项是被动,“被完竭了”.Run out 这个词的主语是something,不需要被动式.不知道说的明白不?
再问: ��ѡ�ľ���B����Ҳ����ô���,���Ǵ�ѡA���ѵ��Ǵ
