请问包含了哪些语法,有什么从句? All you know is that things will

All you know可以看成All that you know,all是先行词,that是know的宾语,所以可以省略.也可以简单点想,you know去掉,all是主语,you know当插入语处理.不过我倾向于前面的理解.
All you know is that后边就是表语了,表语从句.
things will be different这已经是个简单句了,既然有了and,后边又是句子,那就是并列句了
chances are that后边又是表语从句了,如果是chances are somthing that那么就是定语从句,something作为先行词了.可是这个句子不是我刚开始想的那样.
you won't know the kids at your new school是个简单句,主谓宾地点状语.
