Musttheworkbefinishedtoday?今天必须完成这项工作吗？

Whoshouldbeaskedtoanswerthequestion?应该要求谁回答这个问题呢？妙指津含有情态动词的主动句变被动句时，谓语动词部分改为“情态动词+be+及物动词的过去分词”。e.g.WecanwritelettersinEnglish.改为被动语态LetterscanbewritteninEnglishbyus.—Thetrafficistoobusy.Wehavetodriveslowly.—Ithinkmorenewroads________inourcity.A．shouldbebuiltB．shouldbuilt

C．havebuilt

D．build可用语法判断法解答本题。主语roads与动词build构成被动关系，所以应用被动语态。从句为含有情态动词的被动语态。故选A项。
