Has it been warned that all the children in this area_____stay at their homes until the Bird Flu has been controlled?
A.can
B.will
C.may
D.shall
答
选D.shall (用于陈述句中的第二、第三人称,表示说话人的意图、允诺、警告、命令、决心等)必须,应,可 如：（1）You shall have it back next week. 下星期一定还你. （2）He shall stay in bed. 他必须躺在床上. （3）He says he won't go, but I say he shall. 他说他不去,但我说他必须去.此题正是考查此种用法.
