How long do you suppose it is _since_ he arrived here?
为什么是it is这里不是一个疑问句吗?不应该是is

疑问句中疑问句要以陈述句的语序存在.
再问：能举一些例子吗？？
再答： do you know where the post office is? can you tell me it is true?
再问：那问题里的是什么从句算是？
再答：这个很抱歉，因为我个人学习英语的方法和他人不太一样，我从来不记语法，只是自己总结并记住特殊情况而已。所以你要问是什么从句，我只能说，我自己归纳为疑问句中的谓语从句吧。这句话的大致意思是“从他到达这里后，你质疑是否是它有多久了？” 其实这句话的主体结构是you suppose X, 其中X=it is or not, X 在这里充当谓语。since之后的为时间状语。整句话在陈述句语序下的意思是“你猜测是否是它”。那么这里就会发现两个明显的疑问句：how long do you suppose X? 和is it or not? 而作为从句的话，后者的选择性疑问句中，or not 是可以省略的。大体结构可以这样区分。那么在疑问句中，充当谓语的部分，是要用陈述句语序来表述。所以大致可以归纳为一句最简单易记的话就是“疑问句中的疑问句要以陈述句语序存在”。以上大多都是个人学习的归纳总结后的观点。
再问：也就是疑问句中的从句要用陈述预期喽..
