職稱(chēng)英語(yǔ)考試常用句型(41)

If I should ……, I will ……
    結(jié)構(gòu)︰If…should…,…would(will)/should(shall)等+原形動(dòng)詞
    說(shuō)明︰這是表示與未來(lái)事實(shí)相反的假設(shè)<句型>,if <子句>要用<助動(dòng)詞> should,譯成“萬(wàn)一”。should可置于<主詞>前,將 if 省略。<主要子句>的<助動(dòng)詞>則視可能性做變化:若可能性低,則為過(guò)去式,若可能性高,則為現(xiàn)在式。should 可以提前,而將 if 省略。
