M: You are late again. Miss Smith. Don’t you have a watch or something?

W: Yes, I thought that I had set the alarm clock for 7 o’clock, but it rang an hour later.

Text 2

W: Would you mind if I opened the window?

M: Of course not. It’s really hot in the room. Open the window to let in more fresh air.

Text 3

M: Where to, Miss?

W: Please drop me off at the King’s Department Store.

M: On the west side?

W: No, the east side, near the post office.

Text 4

W: Hello. This is Kate from the Rainbow Hotel. Is Jimmy at home?

M: No. He is in the lab, but he will be back home at 4 o’clock.

Text 5

W: I’m going to the store. What would you like me to buy for you?

M: Would you please buy a wallet for me while you are there?

W: With pleasure.

Text 6

W: How do you usually spend your evenings?

M: I usually study. But if there’s a new film on TV, I watch that instead.

W: How about weekends?

M: I usually do some washing and cleaning in the morning. In the afternoon I like to go out to do some shopping or visit some friends.

W: Do you often go to parks or to ball games?

M: Sometimes, but not often.

Text 7

M: Look! Someone is celebrating his birthday.

W: This must be his 21st birthday. No doubt about it.

M: Why? Do you know that guy?

W: No. Well, in America, 21 is the age when you’re allowed to drink. So, many guys celebrate it in bars.

M: That’s interesting. But it would be really expensive, I suppose. Just think abo ut all the drinks. W: No. If it’s your birthday, then you don’t need to pay a cent. Just blow out the candles and open the gifts. That makes the birthday a special day. Your friends will take care of everything.

M: Wow, that’s wonderful.

Text 8

W: Jim has been here for years. Do we have to fire him?

M: Well, in face of the crisis, we have to cut jobs. Besides, with the new machine, we don’t need him.

W: Is there anything else he can do around here?

M: Nothing, I’ve checked. I have no other choices.

W: Mayb e you’re right. OK, I’ll tell Jim.

M: No, Sara. I need to talk to him myself. It was I who asked him to work here.

W: But it might be easier for me to talk to him than for you.

M: No, thanks, Sara. You don’t know what it’s like to be fired.

W: You, a gener al manager, know what it’s like?

M: Yes. I was 30 years old at the time, working in a big company. One morning, I found an announcement on my desk. It said, “Clear your office by noon today.” No explanation, no apology, no thanks for a job well done.

W: That really hurts.

Text 9

W: Excuse me, sir, but we’re doing a survey on what people prefer to do on holiday. Do you mind if I ask you a few questions?

M: No, not at all. Please go ahead.

W: How often do you go on holiday?

M: I generally have a two-week holiday a year.

W: And what do you prefer to do when you are on holiday?

M: Well, I don’t usually visit my family. We live quite close and I can see them any time. But I do like to visit museums and art galleries, especially if there’s a special exhibition on. I don’t like to stay at home, although my parents do. You know, in the morning I prefer to sit under the tree, listening to birds.

W: Do you ever travel overseas?

M: No, I don’t. It’s too expensive for me.

W: What about your wife?

M: She loves to visit the coast in the afternoon. So if the weather’s good, we often go swimming in the sea, or maybe just lie on the beach and enjoy the sun.

W: OK. Well, thank you very much for your time.

Welcome to Guide Dogs Training Center, boys and girls! First let me tell you something about guide dogs.

In 1918 a doctor and his pet dog walked with a soldier who was blind. The doctor went in the hospital for a short time. When he came out, he saw his pet had guided the soldier on the other side of the hospital yard safely. So he taught a dog to guide a person and it worked out well. Germany helped start a program to teach dogs to be guides.

Dorothy, an American woman, went to Germany to find out more about the guide dogs. When she came back to the United States, she wrote about it in a magazine. Soon more people knew about the guide dogs.

The best dogs for the job are clever and fit. It takes more than 2 years to train a little dog to be a guide dog. When the dog is 14 months old, it learns many instructions. Then the owner and the dog meet, and they practice for 4 weeks.

Have I made myself clear? OK, let’s go on visiting.
