Question

___ it rain tomorrow, we would have to put off the meeting.

1.___ it rain tomorrow, we would have to put off
the meeting.
A. Were B. Should C. Would D. Will (上海94)
2.( )it rain tomorrow,we would have to( )the picnic
A.would;put forward B.should;call off C.were;put off D.should;put up
这两题句型没有区别.第2提一定是选C.(因为根据第2个空).那为什么第1题是选B而不选A呢.省略if should were had 都要倒装.这三者又有什么区别呢?谢谢
为什么第2题能用were 第1题不能用were

Answer 1

should it rain tomorrow, we would have to put off the meeting.
if it should rain tomorrow, we would have to put off the meeting.

应为Were it to rain tomorrow, we would have to put off the meeting.
况且rain为动词。答案错误。

虚拟语气倒装 仅should were had 提前，其他不动。were to 与should等效用于对将来的虚拟。were，had分别表对现在、过去的虚拟。具型备如体见虚拟语气用法及虚拟卜启滚尘语气倒装。

Answer 2

肯定是答案印错了

Should 本该做却没做的虚拟罩迟语句

were和had 则是根据渣闷如后面的时态选用

从例句看 后面时态为现在时 所以虚拟用过去时如启

Answer 3

were表示扮禅对野简将来的假设
should表示应该 推测
had表示对过去发生的事情的另一种假设，是过去并不曾发生的，事后诸葛亮
个人觉得选B吧 A。。 如此久远的高考题颂缺裤 想想得问当时的老师了。。

Answer 4

B
因为能提前表示虚拟的只有A/B，但A后面不能接rain
