these days students in some schools are asked not to use mobile phones
这个的主语是什么?难道不是学生吗?为什么这句话是被动语态.(我还没学).我看到被动语态句子的结构 一般动词在人称的前面 还有个by.这句话 就不是啊.求教
these days students in some schools are asked not to use mob
(1) 是被动语态: students in some schools are asked ( by their headmasters=省略了) not to use mobile phones
(2) 如不是被动语态: students in some schools are [asking] their headmasters for permission to use mobile phones.
再问: 被动语态主语不是应该跑到后面去了。。。。主语是啥 是学生吗。。
再答: (3) 主语(subject) 应是"these days students in some schools" 我不是很了解句子分析
