单选题 Speaker A: I just called the travel agency. It's all set. On June first, I'm heading for the mountains for an entire week.
Speaker B: ______? Because our classes aren't over till the seventh.
A. Oh, it is so early, isn't it
B. Are you heading for the mountains
C. But have you checked the academic calendar
D. But what about an entire week

【正确答案】 C

【答案解析】[解析] 说话者A说：“我刚给旅行社打过电话了。一切都定下来了。6月1号，我要到山上玩整整一个星期。”在答本题时，需先把说话者B应答的后半句看懂。她说：“因为我们的课6月7号才完。”由此可知，对话人都是学生，他们可能是好朋友。说话者B的意见是不能因为去玩就耽误了功课。故C对。
