题目内容
11.For the health of people,smoking in the public places has been banned in China since 2011.分析 自2011年以来,为了人们的身体健康,在中国就已经禁止在公共场所吸烟了.
解答 答案:banned
分析句意并结合首字母的提示可知,此处是"禁止"的意思,应填动词ban的某种形式;由于该动词与主语smoking构成的是被动关系,并且根据时间状语"since 2011"可知,本句需要使用现在完成时态的被动语态(has/have been done),故填banned
点评 做本题时,应在正确理解句意或分析句子结构的前提下,结合首字母的提示,判断出所应填写的单词及其相应的形式;因此在平时的学习中,应牢固记忆单词的拼写;并且熟练掌握一些的语法知识;例如本题就考查到了现在完成时态的被动语态的用法.
