题目内容
16.The book must _____ in a week.( )A. | return | B. | is returned | C. | to return | D. | be returned |
分析 一周之内必须归还这本书.
解答 答案:D
根据主语the book是谓语动词return的承受者,二者是被动关系故用被动语态,又知句中含有情态动词must故该空处用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,故选D
点评 本题考查被动语态,做此类题,首先判断主语与谓语动词的关系,其次根据句中含有情态动词,可判断为含有情态动词的被动语态,然后二者结合套用结构情态动词+be+及物动词的过去分词.
