单选题 Speaker A: Good afternoon, I'm here for my four o'clock appointment with Dr. Brown.
Speaker B: ______
  • A. Nice to see you. I'm Dr. Brown's secretary.
  • B. Why don't you have a seat for a moment?
  • C. Excuse me, when did you make this appointment with him?
  • D. I'm sorry. He will be busy the whole afternoon
【正确答案】 B
【答案解析】A方的话表明他是应约来见布朗大夫的，B方可能是布朗大夫的秘书或助手，由她接待A方。B项“你干吗不坐一会儿?”是对A方作出的恰当反应。A项除了问候外，还作了自我介绍，不符合对话场景的要求。C和D项均与A方的话语不一致。
