(Wind noises) 录音时注意此处请加上有风吹的背景

W: Oh, God! I thought it was supposed to get warmer today.

M: I thought so, too. That’s what the weatherman said.

W: It must be the wind that makes it so cold. I’m freezing!

Text2

W: Is this where I catch the bus for the zoo？

M: You can take a T-30 from here, but then you have to walk six blocks.

W: That’s bad. I’m too tired. Maybe I should take a taxi.

Text3

M: One step left. Good! Look at the building and point to it. Great! Lift your head a bit, Fantastic!

W: Is it done?

M: Yes, perfectly! Wait for one minute and you’ll see the picture!

Text4

M: How was the job interview? I think you’ll make a good journalist. I remember you as the best writer in the class.

W: Well, in fact, my application was turned down. They were looking for people with experience in the profession.

Text5

W: Can you say something on the matter? You are the only person who knows what really happened.

M: That’s not quite true. Stan Bailey was there, too.

W: Oh. Was he?

M: Well, actually, he wasn’t there all the time, but still I think he can give something valuable in sight.

Text6

M: Where are you from?

W: The United States. I live in New York.

M: Oh, really? I think it’s a big city with a large population, right? By the way, do you like it?

W: Yeah. I think it’s the only place to live.

M: Why do you say that?

W: You see, there’s always something exciting to do, and it’s never boring.

M: My place isn’t boring, either, You can fish, hike, grow some flowers and vegetables – all kinds of things, if you like, though it’s small and quiet.

W: I guess so, especially here in New Zealand.

Text7

M: Are you quite independent of your parents now?

W: Yes, as soon as I left school and started my study as a nurse, I stopped asking my parent for money since I got financial support from the government, but I still stay with them a lot.

M: You seem very close to your parents?

W: I am. They never force me to do anything I didn’t want to do. What about you?

M: Well, I am also fond of my family, but I don’t always get on very well with them, they try to control me too much.

W: But they allow you to come to study in England on your own.

M: Yes, but only after a lot of persuasion. Your parents treat you as an adult, mine treat me as a child.

W: I saw you on the news last night, Jack. So tell us what happened?

M: Well, I was walking alone on the beach when I heard someone calling out for help. I looked up, and saw a little boy up on the cliff, stuck there.

W: What did you do then?

M: Well, my first thought was to run and get help, but the boy was crying, looking as if he would fall off the cliff at any moment. So I climbed up to get him down. The rocks were very loose. You know, and I even slipped a couple of times.

W: Sounds scary. What happened next?

M: I reached the boy but couldn’t get him down. We were both stuck.

W: So what did you do?

M: Well, I called for help. Pretty soon there was a small crowd on the beach but no one knew what to do. And then someone called the Coast Rescue Service.

W: Wow! That was really adventurous.

Text9

W: You’re so involved. What are you reading?

M: You know Snoopy? That lovely dog always tells us the truth of life in his simple words.

W: I like the Snoopy series, too. I thought you wouldn’t like cartoons. Don’t you feel them too childish?

M: Not at all. Cartoons are fun not only for kids, but also for adults.

W: I quite agree. We adults need simple and interesting things in our stressful lives.

M: I like cartoon movies, too. Many of them are great works.

W: Me too! What’s your favourite one?

M: Ice Age. It’s fantastic!

W: Tell me something about the movie. I’ve heard about it, but I’ve never seen it.

M: Oh, really? It’s a rather old movie, coming out around 2003. It’s so classical that you shouldn’t have missed it. It’s a story about what happens to a group of animals at the end of the Ice Age. The pictures are beautiful, and the whole movie is very imaginative.

W: Are there just animals? No humans?

M: There are only a few humans. Not as hateful as they are in other cartoon movies.

W: Oh, I cannot wait to see it.

M: I have a DVD of this film. I’ll bring it to you tomorrow.

W: Thank you very much!

Twin sisters are supposed to be very much alike, are they not? Well, my twin sister Jane and I do look alike. However, we are different in many ways. I care little about clothes. T-shirts and blue jeans are my favorite clothes. My sister often dresses like a model. We have very similar characters in most ways. I don’t get angry and enjoy being with friends. In this respect, my twin sister feels the same. But she likes loud music and modern dances while I find that night clubs give me a headache. She is always with friends, is the favorite of our teachers and never wants to have children. I prefer to be alone at times, don’t really try to please my teachers and want to some day to have a family of my own. We have tried to live in the same room several times and even agreed on the color we like best and the kind of furniture we want. But I like to keep things neat and orderly while my twin sister acts as if there were a servant around to pick up all the things that get thrown on the floor. I like to go to bed early and get up early. She often goes to bed very late and then sleeps late next day.
