Speaker A: Could you give me a ride to the conference center? My presentation is in about half an hour.

Speaker B: __________Have you checked with Bob? He seems to be on his way there about this time.

A. I'm sorry. Perhaps next time.

B. I'm glad to. But it's too late.

C. I'm afraid I am going to the opposite direction.

D. Excuse me, but I'm going to the conference center.

C【解析】说话者A请求说话者B：“你能开车顺路送我到会议中心吗？我的演讲大约半个小时后开始。”说话者B对说话者A回答说“……你问过Bob吗？大概这时候他好像也要往那儿去。”由后半句推知前半句答案应为C，即说话者B要往相反的方向去。
