问题补充:
Being examined twice a year, whether it is a car or a bus or a truck, it is the rule that every driver obey in this city.
A. shall
B. can
C. has to
D. need
答案:
(答案→)A. shall
B. can
C. has to
D. need
解析:考查情态动词用法。本题中的shall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。本句中是指按照规则要做的事情。句意:无论是汽车,公交车还是卡车,两年检查一次,这是一个任何司机都要遵守的规则。故A正确。
