题型:不详难度:来源:
If Mr. Dewey­ _____ present, he would have offered any possible assistance to the people there.
A.wereB.had beenC.should beD.was

答案
B
解析

试题分析:考查虚拟语气用法。本题考查的是if条件从句与过去事实相反的虚拟语气,故从句用had + v-ed,主句用would / could/ should / might + v-ed。句意:如果Dewey先生在场的话,他会提供那里人们的任何可能的帮助。故B正确。
【知识拓展】
1. 表示与现在事实相反或不可能发生:条件状语从句:一般过去时(虚拟语气中be→were)主句用:would(should, could, might)+动词原形。
If we had time now, we would read it again.
If I were you, I would work hard.
2. 表示与过去事实相反或不可能发生:条件状语从句:had+过去分词;主句:would(should, could, might)+have+过去分词。
If I had known your telephone number then, I would have called you.
3. 表示与将来的事实可能相反或不可能发生:条件状语从句:①一般过去时②should +动词原形③were to+动词原形;主句:would(should, could, might)+动词原形。
If it should rain, the crops would be saved.
