一道英语语法单选~
The human body is made up of over 75% of water,____we can only survive for acouple of days.
A.without it
B.without which 为什么选B 从句缺成分么?which 不是占成分么

从句不缺成分
we 主语
can survive.谓语
主谓齐了
which 作引导词,引导后面从句
再问：如果单用which 不行吧？
再答：不是很明白你的意思，你是说which 后面从句单独作为一个句子么？
再问： which是关系代词这道题如果不应介词+关系代词直接用关系代词是不行的吧。。单独的which在句中做成分而加了介词whthout就不做成分了
再答：不能这样理解，这里跟介词是没有关系的，无论加不加介词，这里的which成分是一个的，都是指代water。完整句子还原是这样的，The human body is made up of over 75% of water and without water we can only survive for acouple of days. without这个介词本身就在这个句子里面，他跟water连起来成为一个状语，而在定语从句中，without还是和原来的成分一样，water 就由which指代了。说得好像有点乱，不知道你看不看得明白，欢迎追问。
