题目内容

1．-Must we clean the classroom now？
-No，you needn't．It after school．（　　）

A．

may clean

B．

must clean

C．

need be cleaned

D．

can be cleaned

分析 -我现在必须打扫教室吗？
-不，不必．可以放学后打扫．

解答答案：D
结合句子语境"我现在必须打扫教室吗？不，不必"可知It…after school表达的是允许对方在放学后打扫，允许（做某事）可用情态动词can，情态动词need在肯定句中表达"需要（做某事）"与该题表达的意思不符，故该句中确定用情态动词can；又知该句的主语it代指the classroom是谓语动词clean的承受者二者形成被动关系，故谓语动词为含有情态动词的被动语态，其结构为情态动词+be+及物动词的过去分词；套用结构故填can be cleaned，故选D

点评本题考查含有情态动词的被动语态，首先结合语境确定恰当的情态动词，再套用该被动语态的结构（情态动词+be+及物动词的过去分词）即可选出正确答案．
