答案
A
解析

试题分析:考察情态动词用法。本题考察了情态动词shall的特殊用法,shall还可以可用于二、三人称的肯定句中表示说话人给对方的命令、警告、允诺、 威胁等。也可以用于根据法律法规必须做某事。如According to law, you shall give all your money to your daughter。本题正是考试的规则。句意:据宣布,所有的考生要坐在原来的位置上直到所有的试卷都被收起来。故A正确。
点评:在平时的学习中既要注意情态动词的基本含义,也要注意情态动词的特殊意义,如must偏偏,非得;should竟然;mustn’t禁止,千万不能;等等。情态动词Shall用于所有人称,表示命令,警告,允诺;以及法律规定中要做的事情。
