问题描述：
When children live at school,they cannot rely on their parents any more and have to ...
When children live at school,they cannot rely on their parents any more and have to
deal with all problems by themselves.求问句子中为什么用“逗号”以及逗号前后两句分别是什么成分,
还有个句子问题一样：
After they are sent to boarding schools,they become less
dependent on their parents.
答
这两个均是时间状语从句 有主句 有从句分别是两个句子当把两个句子拆开时都可以单独存在但是当合在一起时 他们仍然是两个句子所以中间要用逗号进行连接.不能说“逗号前后两句分别是什么成分” 因为一个句子由很多成...非常感谢哈 在麻烦一下 比如第一个句子 如果想写成一个句子就是不用逗号 应该怎么写万分感谢They cannot rely on their parents any more and have to deal with all problems by themselves when children live at school .when 和 after 等引导词 所在的从句 在后面，主句在前面 时 就可以不用逗号了
