另有一题
＿＿ese buildings met strict design requirements,more and more students would have survived the earthquake
A.Had B.Were
是不是had用在表示与过去情况相反而were用在与现在或将来情况相反？表示虚拟的过去，现在，将来，分别有什么区别？？？

A.
Had these buildings...

had 表示过去而不是进行时.如果用were是错误的,因为building是地震以前建筑的.所以要用had表示已经过去的事情.

had可以作代表和过去情况相反的句式的第一个单词, 但是were不能作代表和现在或将来情况相反的句式的第一个单词.

A
虚拟语气中，主句表示与过去事实相反，要用过去完成时，如果省略if, 句子要到装。也就是Had提前

were是什么的过去式？has和had有什么区别 i were not see him since 1995.和i had not see him since 1975有什么区别啊。有一道英语题,题目为_friends Betty had made there were all invited to her birthday party. 虚拟语气中与将来事实相反情况从句中were to 与should用法的不同? there were,too,many children there与there were too many children there有什么区别? 虚拟语气一定都用were吗 had 放在句首是不是可以表一种假设的虚拟 has 和had，was ，were这些都是什么形态 What were the consequences of the decision she had made ___came that we had to stay where we were.
