---I am going to Nanjing and stay there for a week.

---____________ you are there, would you please buy some books for me?

A.If

B.While

C.Since

D.As soon as

答案

B

题目分析: 句意:我打算去南京在那儿呆一周。你在那的进候,可以给我买几本书吗? If如果,While           当……的时候,Since自从,As soon as一……就……。since引导的从句用一般过去时,在南京呆一周,没必要一到那儿就去买书,已经计划去南京了,不必再进行假设,while引导的从句动词用进行时态或一种状态。故选B。
