分析一下这句话的句子结构,所用的语法
It's definitely been shown in all different ways that when you put a whole population under a stressor that sudden death will increase.
答
it形式主语
has been shown被动结构,位于成分
in all different ways 方式状语
that从句,主语从句,真正的主语.
其中that从句里面,when从句是时间状语从句,后面的that从句才是真正的从句结构,包含了主谓成分.最后真正的主语里正常语序是不是就是sudden death will increase when you put a whole population under a stressor ，那为什么sudden death will increase前要加thatthat sudden death will increase这是真正的主语从句，最前面的that是定语从句，修饰ways。
