Question 5 is based on the conversation you have just heard.

5. W: I can’t find the arrival time of the New York to Boston Express on this schedule.

M: Look for New York in the left-hand column and follow it across until you find the hour listed in the Boston column.

Q: What are the speakers most probably doing?

正确答案：B

解析：女士对男士说在时刻表上找不到从纽约到波士顿的快车的到达时间，男士让她在左边一栏里找到纽约，然后沿着它横向寻找，直到找到波士顿一栏里的到达时间。由此可见，两位说话者在看列车时刻表。
