衛(wèi)生類職稱英語備考句型：

If I should ……,I will ……

結(jié)構(gòu)：If…should…，…would（will）/should（shall）等+原形動詞

說明：這是表示與未來事實相反的假設(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。

If he should come,I will tell him the truth. 萬一他來，我一定會把真相告訴他。

Should the boy come again,I would throw him out. 要是那男孩在來，我就把他攆出去。
