Sometimes that is exactly what happens when things don't turn out the way they should.句型结构
问题描述：
Sometimes that is exactly what happens when things don't turn out the way they should.句型结构
帮忙讲讲句型结构,有点看不懂~
答
what引导的从句作is 的表语,when引导的是时间状语从句,然后从句中things作主语,turn out 谓语,the way 宾语,后面的they should作定语
整个句子的意思是“有时候当事情不像它应有的方式出现,事实就是这样（它就是这样发生的）”
