题目内容
13.-Smoking should in school.--I agree.It's bad for our health.( )
| A. | be allowed | B. | not allow | C. | allow | D. | not be allowed |
分析 翻译:--在学校吸烟应是不允许的.
--我同意.这对我们的健康不好.
解答 答案:D.根据句中关键词选项中allow可知,应是被允许做/不做;结合句意,表示吸烟不被允许,故用否定形式和被动语态.should是情态动词,其被动语态是:should not+be+过去分词,结合选项,故选D.
点评 含有情态动词的被动语态,结构是一样的:情态动词+(not)+be+过去分词;此题根据情态动词的被动结构是解题的关键.
