為了幫助廣大考生有效備考2014年全國職稱英語綜合類考試，小編特編輯整理了職稱英語考試假設(shè)法句型講解，希望對您通過2014年職稱英語考試有所幫助！

結(jié)構(gòu)︰If I+should ...+祈使語氣

說明︰代替，增加了條件的不確定性。本句型常用在想禮貌地提出要求或建議，或者想圓通地告訴他人該做什么事的場合。用 should 起始句子即可不用 if 而表示條件。這種用法比較正式，常用于諸如公函之中，而不用于日常會(huì)話。

Should you see him, please give him my regards. 如果你見到他，請代我向他致意。

If you should happen to see him, please give him my regards.

If I should ..., I will ...

結(jié)構(gòu)︰If…should…，…would(will)/should(shall)等+原形動(dòng)詞

說明︰這是表示與未來事實(shí)相反的假設(shè)，if 要用 should，譯成“萬一”。should可置于前，將 if 省略。的則視可能性做變化：若可能性低，則為過去式，若可能性高，則為現(xiàn)在式。should 可以提前，而將 if 省略。
