Question

帮忙分析下英语长难句子呗,
After all,it has an ad business too,which it says will comply with DNT requests,though it is still working out how.

Answer 1

after all做状语,it has an ad business too是主干；定语从句which it says will comply with DNT requests修饰an ad business.里面的it says是插入语；后面的though it is still working out how是关系从句
