(·长春市一模)—Is this Mr. Whites office, Mary?

—Yes，.

A. all right

B. it doesn matter

C. after you

D. help yourself

答案：

A. all right

B. it doesn matter

(答案→)C. after you

D. help yourself

解析：选C考查情景交际。句意：“玛丽，这是怀特先生的办公室吗？”“是的，您先请。”此处表示出于礼貌，让别人先进，after you表示“您先请，请先走”。all right“好吧”；it doesn matter“不要紧”；help yourself“请随便用，请自便”。
