Question

Have you ever had the same experience as he does/ had?

应该用哪个呢？请解释，谢谢

Answer 1

had.
Have you ever had the same experience as he had?
你有过和他相似的经历吗？
从句意思可知，他已经经获得这样的经历。所以用had>
as 引导限制性定语从句，主要用于the same…as（与……相同），such…as（像……一样），as…as（与……一样）。通常主从句的时态是一致的。
如： She knew he felt just the same as she did. 她知道他的感受和她一样。 Such a man with a good temper as Mr. Li is is easy to get along with. 像李先生这样好脾气的人是容易相处的。 He smokes as expensive a cigarette as he can afford. 他抽一种他买得起的最贵的烟。

Answer 2

has= =第三人称单数

追问

不受前面儿时态的影响？
