题目内容
2．These books ________ out of the library．You have to read them here．（ ）| A． | can't take | B． | must be taken | ||
| C． | must take | D． | mustn't be taken |
分析 这些书一定不能拿出图书馆．你不得不在这里读它们．
解答 答案：D 根据这句话的主语these books是动词take的承受者，从而构成被动的关系，应该用被动语态．再根据You have to read them here可知一定不能把书拿出图书馆表达否定意思；结合选项中的情态动词可知，应该用含有情态动词的被动语态的否定结构，其构成为情态动词+not+be+及物动词的过去分词，这里应当用mustn't．故选D
点评 在本题中首先根据主语和谓语动词的关系，判断其语态是被动语态，结合选项中的情态动词及句中表达的否定意义，判断用含有情态动词的被动语态的否定结构，其构成为情态动词+not+be+及物动词的过去分词，结合该结构可很快选出正确答案．
