Question

请分析一下这个英语句子的成分。

No matter what it is, chances are that it happened when you were older than 3, because previous studies of adults have shown that very few people can recall (回忆) memories from before the age of 3.

Answer 1

no matter what it is虽然可以作为前置代词理解，但从语义上来说理解为插入语就好，在分析结构的时候同……，I think，……一样可以扔到一边。（不过你确定这里不该是what they are吗？）
chances are 主谓，that it……3.是从句修饰chances。because连接词，连接两个完整的句子。studies……shown是另一个主谓，that……3是从句修饰studies

追问

【that……3是从句修饰studies】为什么不能把that...3看成shown的宾从。哪里是because后面引导的两个完整句子。【studies……shown是另一个主谓】不明白。

追答

that……3确实应该是shown的宾从，之前没理清。because不是引导是连接，前后各一个。studies……shown是另一个主谓就是说这句是第二个句子

追问

哦。那么【chances are that it happened when you were older than 3】中when引导的是时间状语从句吗？？

追答

是的。这句话感觉有些很口语的表达，没必要深究结构了
