问题描述：
I am going to Qingdao and stay there for a week.
____you are there,would you please buy some books for me?
A.ifB.whileC.sinceD.as soon as
为什么不用A
答
B
你在那儿的时候，请帮我买几本书好吗？
他/她去青岛是不争的事实
希望对你有帮助
答
A 是假设。而前面已经说了，他要去呆一周，所以不是假设
答
B.while 是对的.
第一个句子已经明确表示going to Qingdao ,故不再存在“如果.”.只能说“当你在那里.请帮我.好吗?”
答
if --根据句意 虚拟语气 后面用were if you were there
