问题补充：

---What if I have to go there and know nothing about it?

--- If I you, I would try to find some information about it on the Internet.

A. am

B. was

C. will be

D. were

答案：

A. am

B. was

C. will be

(答案→)D. were

解析：句意：——倘若我必须去那儿而且对那里一无所知，该怎么办？——如果我是你，我会在网上查找一些有关那里的信息。根据 I would try to find可知主句用的是would+do,可知这是对现在事实的假设的虚拟语气，因此If引导的条件状语从句用一般过去时，根据虚拟语气的用法be动词在If引导虚拟语气中用were .故选 D。
