题目内容：

There are no conditions to which a man cannot become accustomed.是宾语从句?可以用that替换which吗?
这是原句
There are no conditions to which a man cannot become
accustomed,especially if he sees that all those around him live in the same way.

优质解答

这不是宾语从句,而是定语从句,先行词是condition.
不能用that替代,因为前面有介词to.
为什么有介词to?是因为【be accustomed to】是固定词组搭配,定语从句中要提前到which前.
翻译：【没有任何情况一个人是不能够适应的.】
