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】說話者A請求說話者B：“你能開車順路送我到會議中心嗎？我的演講大約半個小時后開始。”說話者B對說話者A回答說“……你問過Bob嗎？大概這時候他好像也要往那兒去。”由后半句推知前半句答案應為C，即說話者B要往相反的方向去。
