题目内容
13.-Can I smoke here?-Sorry,smoking _________.( )
| A. | not allow | B. | isn't allowing | C. | doesn't allow | D. | isn't allowed |
分析 -我能在这吸烟吗?
--对不起,吸烟是不被允许的.
解答 答案:D 根据主语"smoking"与动词allow的关系,吸烟这个动作是"允许"的承受者,可知应用被动语态(be+done).allow的过去分词为allowed,吸烟不被允许是事实,用一般现在时,动名词做主语,谓语动词用单数,故选D.
点评 本题考查一般现在时的被动语态.首先要根据主语与动词的关系判断用被动语态,其次判断时态.
