题目内容
1．Teenagers ______to smoke．（ ）| A． | shouldn't allow | B． | should be allowed | ||
| C． | shouldn't be allowed | D． | D |
分析 年轻人不应该允许抽烟．
解答 答案：C．allow sb to do sth 允许某人做某事，主语teenagers是动词allow的承受者，故用被动语态sb be allowed to do sth，这里是表示不允许抽烟，故用shouldn't，故答案是C．
点评 被动语态（passive voice）是动词的一种形式，用以说明主语与谓语动词之间的关系．英语的语态共有两种：主动语态和被动语态．主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者．被动语态是动词的一种特殊形式，一般来说，只有需要动作对象的及物动词才有被动语态．汉语往往用"被"、"受"、"给"等被动词来表示被动意义．
