Question

Should it rain, the crops _____ .

A．would be saved	B．would have been saved
C．will be saved	D．had been saved

Answer 1

A

试题分析：本题中存在if虚拟语气省略现象，还原为if it should rain,从句对将来进行虚拟，主句用should + do。故选A
点评：与现在事实相反，if从句用did（be动词用were），
主句用would/should/could/might/+do.
与过去事实相反，if从句用have + done，
主句用would/should/could/might/+ have done.
与将来事实相反，if从句用should + do；were to do；did，
主句用would/should/could/might/+do.
如果虚拟条件句的谓语部分有were,had 和should时，可省略if，把were，had和should提句首，变成倒装句。
