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

試題分析：本題中存在if虛擬語(yǔ)氣省略現(xiàn)象，還原為if it should rain,從句對(duì)將來(lái)進(jìn)行虛擬，主句用should + do。故選A
點(diǎn)評(píng)：與現(xiàn)在事實(shí)相反，if從句用did（be動(dòng)詞用were），
主句用would/should/could/might/+do.
與過(guò)去事實(shí)相反，if從句用have + done，
主句用would/should/could/might/+ have done.
與將來(lái)事實(shí)相反，if從句用should + do；were to do；did，
主句用would/should/could/might/+do.
如果虛擬條件句的謂語(yǔ)部分有were,had 和should時(shí)，可省略if，把were，had和should提句首，變成倒裝句。
