1．(2011年南昌调研)“Attention，please.Whoever can answer one of my questions________receive a prize，”the teacher said in class.
A．might B．shall
C．should D．would
解析：选B。考查情态动词。shall用于第二和第三人称时，可以表示警告、命令、允诺、威胁等语气；might表示可能性很小；should表示“应该(义务性)”；would表示意志(意愿性)。由此我们不难判断这里选B项表示允诺。
2．(2011年湘潭模拟)—Why did you leave without a word of warning to John?
—But what________otherwise？He never listens to me.
A．could I do B．could I have done
C．must I have done D．should I do
