Those responsible for the accident be punished while those contributing to solving the problems be rewarded, promised the official then and there.A.needB.mayC.canD.shall

D解析试题分析：句意：这位官员当场允诺：事故的责任人将受到惩罚，而对于解决这个问题做出贡献的人将给予奖励。need需要；may可以；can能够；shall表示命令，威胁等。这里是shall表示命令，故选D。考点：考查情态动词的用法。点评：本题难度适中。即学即练：“Everyone ________ not fire without the signal or you’ll be severely punished or even killed,” urged the commander. A. would B. might C. shall D. need解析：C。shall用于第二、三人称表示“允诺，警告，命令”等语气。这里是表示“命令”的语气。

这个问题我还想问问老师呢
