Question

17．任何人都不允许在公共场合抽烟．
Anybodyisn'tallowed to smoke in public．

Answer 1

分析 isn't allowed．

解答 答案：isn't allowed．主语anyone是动词allow（允许）的承受者，构成被动关系，允许某人做某事allow sb to do sth，这里是说客观事实用一般现在时，故用一般现在时的被动语态am/is/are+过去分词，主语是不定代词，谓语动词用单数，故is，加上否定not，故答案是isn't allowed．

点评 allow作"允许"或"许可"讲，常搭用动词不定式短语作宾语补足语即，allow sb．to do sth．允许某人做某事．allow 作"许可"，"允许"讲，只可搭配动名词短语作宾语，不可直接搭用动词不定式作宾补，即只可说 allow doing sth．，不可说allow to do sth．
