M: Don't worry about your train sickness. I have brought some tablets with me that prevent train sickness. Here, take this one now. I'm sure you'll be alright on the train. ,F: It's very kind of you. By the way where is the dining car? ,M: The dining car is next to the sleeping car. Shall we eat our meals in the dining car? ,F: The attendant will bring some food here. But since the dining car is next to this carriage, we may just as well eat there. ,M: That's alright. How beautiful the scenery is. Look at the vast stretches of green fields. ,F: But it looks lovely only at this time of the year. It's rather dull and lonely in winter. ,M: That's why I prefer to travel in the summer and autumn. ,F: Me, too. I love summer, though it is hot. ,M: The train's pulling in. Do we have time to get offen stretch our legs? ,F: You may go out if you want. The train will stop for 1/4 of an hour before it continues on its way. Whatever you do, don't miss it.

M: Hey Lindaï¼ did you get that letter about the new options for food service next year? ,F: Not yet, are there a lot of changes? ,M: There sure are, instead of paying one feet to cover all meals for the whole school year. We are now able to choose how many meals a week we want, and can contract just for that amount. We still have to pay the whole year at the beginning, but we can choose to buy 7, 10, 14 or 21 meals per week. They give you a card with a number of meals you get each week marked on it. ,F: That's a big change Tom, and a complicated system. ,M: Yeah, but it will be much better for people who don't eat 3 meals a day 7 days a week in the cafeteria, because they don't have to pay for meals they don't eat. ,F: So, what's the deal for those who do eat at school all the time? ,M: It better for them, too, because the more meals you contract for, the cheaper each one is. ,F: I see, it still sounds rather complicated. ,M: True, it took me several hours to figure it out. I decided to go with the 10 meal plan. ,F: Why is that? ,M: Well, I never eat breakfast and I often go away on weekends, so the 10 meal plan gives me lunch and dinner every weekday at a fairly low price, and I won't be paying for meals I don't usually eat.
(A) F: You are right. You will benefit from the changes next year. That is good. (B) F: That is true. You will benefit from the changes in our company. It is good. (C) F: I totally understand why you dislike the changes in our company. Do not be sad. (D) F: I am really sorry, I did not catch that. Would you slow down, please?
