问题补充：

An emergency meeting will be held tomorrow, at which the bill to pass.

A. is expected

B. will be expected

C. expects

D. will expect

答案：

(答案→)A. is expected

B. will be expected

C. expects

D. will expect

解析：考查时态和语态。at which相当于where，引导非限制性定语从句，bill与expect是动宾关系，应该用被动，排除C、D；expect期待，有望，本身表将来，不用于将来时。故选A。
