题目内容
2.-Don't smoke here,Dad.Smoking( )in public places.-Oh,sorry.I'll stop right now.
| A. | isn't allowed | B. | aren't allowed | C. | doesn't allow |
分析 句意:--不要在这里吸烟,爸爸.在公共场所不允许吸烟.--哦,对不起,我马上停止吸烟.
解答 根据Don't smoke here,可知此处不允许吸烟;又根据smoking作主语,可知此处所使用的语态应该用被动语态,smoking作主语时,谓语动词应该用单数.故选A.
点评 本题考查了被动语态的知识:被动语态由be+动词的过去分词构成,其否定形式在be后面加not即可.
