The details depended on which newspaper you read.为什么不The details depended on you read which newspaper
问题描述：
The details depended on which newspaper you read.
为什么不The details depended on you read which newspaper
答
depend on后面的宾语从句，其引导词必须放在从句句首啊。
which newspaper就是该宾语从句的引导词，必须放在you read前面，尽管它在从句中的确做read的宾语。
再如：I don't know how old you are.就不能说成：I don't know you are how old.
答
这里其实是两个句子,The details depended on… + which newspaper did you read?
可以改写成depend on the newspaper you read
这里是把整个疑问句做on 的宾语、疑问句做宾语要改为陈述语序,
就好像 I want to konw how old you are、I want to know if you will marry me
