答案：
A. how long will the new teaching building be completed
(答案→)B. how soon the new teaching building will be completed
C. how long the new teaching building will be completed
D. how far will the new teaching building be completed
解析：考查宾语从句。宾语从句用陈述句语序。排除A、D；how soon“多久之后”用于将来时，而how long“多长时间”，常与完成时连用。句意“你能告诉我再过多久建好教学楼吗？”故选B。
