听力原文：W：I just want to eat out, I don't think we have enough time to make dinner.
M: Most of the restaurants put too much oil to the meal in order to make the meals taste delicious; actually it's bad for our health.
Q: What does the man mean？
(16)
A．They should go out for dinner.
B．He loves to eat oil meals.
C．The dishes made in the restaurant are more delicious.
D．They'd better make dinner at home for the sake of health.
听力原文：M Were you able to finish writing that article？
W Yes, I'm almost done. I have most of the information that I need. I haven't started writing it yet, but it shouldn't take me too long.
M Well, we have some space to fill in the Sunday edition. If possible, I'd like to put your article in the Lifestyles section. How soon would you be able to finish it？
W I just need to confirm a few quotes, and then I can start writing. I can give it to you by 9 at the latest.

听力原文：M: What do you plan to do for Christmas？
W: No concrete plan, but I think I'll most likely go skiing in Montana and spend a few days in the mountains doing cross-country skiing.
M: I heard you are very good at skiing. Believe it or not, I haven't done any skiing in my life. I wish I could ski just like you.
W: Yeah, you could if you gave it a shot. You know, skiing is my love and the only reason I like it so much is because it gives me great pleasure to speed through the snow.
M: My parents and I vacationed in Montana National Park when I was little and I remembered we had great time going hiking. Now I feel like going back again.
W: Well, since we have two weeks' break for Christmas, you can spend a few days in Montana and I can give you lessons on skiing. That would give you some basics and hopefully you can ski like a professional in a few days.
M: Ski like a professional？ No way. Actually, you do have a good point. I could spend some time in Montana and head back home for Christmas. Perhaps you could spend Christmas at my place too. My parents would like to meet you.
W: That would be great, since my folks will be in Jamaica for Christmas and New Year.
M: Oh, I am anxious to learn how to ski.
W: And you can bet I will be a very strict instructor.
M: No problem. I have been known to be an excellent student during my school year.
W: Well, maybe you won't be this time.
M: Really？ I am looking forward to it now.
W: OK. Then, let's wait and see.
(4)
A．The pleasure of skiing.
B．The Montana National Park.
C．How to learn to ski.
D．How to spend the Christmas holiday.
听力原文：M: What do you mean by a friend, Jean？
W: Oh, Robert, to me, friendship is the most important thing in life. It's more important even than love. If you love someone, you can always fall out of love again, and that can lead to a lot of hurt feelings, bitterness, and so on. But a good friend is a friend for life.
M: Someone who likes the same things that you do, who can argue with and not lose your temper, even if you don't always agree about things. I mean someone who you don't have to talk to all the time but can be silent with, perhaps. That's important, too. You can just sit together and not say very much sometimes. Just relax. I don't like people who talk all the time.
W: Are you very good at keeping in touch with your friends if you don't see them regularly？
M: No, not always. I've lived in lots of places, and, to be honest, once I move away, I often do drift out of touch with my friends. And I'm not a very good letter writer, either. Never have been. But I know that if I saw those friends again, if I ever moved back to the same place, or for stone other mason we got back into close contact again, I'm sure the friendship would be just as strong as it was before.
W: Several of my friends have moved away, got married, things like that. One of my friends has had a baby recently, and I'll admit I don't see her or hear from her as much as I used to...She lives in another neighborhood and when I phone her, she always seems busy. But that's an exception. I write a lot of letters to my friends and get a lot of letters from them. I have a friend I went to school with and ten years ago she emigrated to Canada, but she still writes to me every month, and I write to her just as often.
(23)
A．Those who like the same things that you do.
B．Those who you can argue and not lose your temper.
C．Those who you don't have to talk to all the time but can be silent with.
D．All the above.
