分析 许多国家不允许在公共场合抽烟.因此你肯定不能在这里抽烟.
解答 答案:B.
根据Smoking ______ in public places in many countries.So you ______ smoke here.在公共场合抽烟在许多国家不被允许.因此你肯定不能在这里抽烟.句子的主语是现在分词,现在分词做主语时,谓语动词用单数;再结合主语是在公共场合"吸烟",应用一般现在时的被动语态,其构成是:be+及物动词的过去分词;can't不能,不会;may not不可能;mustn't表示禁止,不允许;结合语境,"在这儿吸烟是绝对不行的",对吸烟的把握最大;故选B.
点评 在学习中熟练掌握知识点,做题时先找出考点(一般现在时的被动语态、情态动词否定形式),根据它的构成结构(be+及物动词的过去分词)再结合语境来选出正确的答案.
