A. do you go to Tibet（西藏）

B. did you go to Tibet

C. are you going to Tibet

D. you are going to Tibet

答案：

A. do you go to Tibet（西藏）

B. did you go to Tibet

C. are you going to Tibet

(答案→)D. you are going to Tibet

解析：句意:-你能告诉我你为什么打算去西藏吗？-因为我想帮助那里的人。这句话中why 引导的是一个宾语从句，做动词tell的宾语。宾语从句中应该用陈述语序，故排除A、B和C。选D。
