Li Qiang is interviewing Walker Hiller on the space station about his idea for building a new town called Wonderworld on Mars. Listening Text CAN PEOPLE REALLY LIVE ON MARS?
LQ: Well, Mr Hiller! Why did you think of building a new town on Mars?WH: It sounds astonishing, doesnt it? I imagine that itll be difficult and the atmosphere, gravity, and climate will have to be just like the earth or nobody will travel there.
LQ: Can you imagine how thatll be achieved?WH: Yes, I think so. The atmospheres too hot and has no oxygen. So people couldnt breathe Mars air and live. Well make a covered area for people to live in with a special air supply.
LQ: Is it likely you can find and use water to keep the climate similar to that on the earth?WH: Perhaps. We hope theres water under the planets surface. People will have to collect all the used water so it can be cleaned and recycled as rain. Then it can be used again to water plants and crops and provide clean drinking water.
LQ: Yes. I suppose everyone will have to put their dirty water in special tanks. Even animals will have to be trained to go to the toilet in special places.WH: Yes, I suppose so.LQ: So is it likely that bacteria will clean the water?
WH: Well, thats a possibility.LQ: I wonder if the houses can be made strong enough against the gravity on Mars?WH: Yes, they can. The dimpods will provide special building material.LQ: Still life sounds quite uncomfortable. So whats the advantage of going to live on Mars?
WH: There will be opportunities for scientific work and to look for gold or other metals. So people may become rich or famous.LQ: How healthy will the people be, I wonder?

Where will the quilt work best? It will work best in ___________ winters and _____________ summers.cold and dryhot and humid
London, UKhumid all year round good in the winter for London but not all year because the quilt would not be cool enough in the summer
Toronto, CanadaVery cold, dry winters good in the winter for Toronto
Cape Town, South Africa hot, dry summers No, not humid enough in the winter for the quilt to work.
Mombassa (), Kenya () hot, humid summers ideal in the summer as a cool quilt.
Yakutat (), North USA very cold, dry winters ideal in the winter as it works well in the winter.
Amsterdam, Holland humid throughout the year; not too cold or hot climate not extreme enough for the quilt to work well.
Athens, Greece hot, humid summers and damp cool winters good in the summer but too hot for the winter.
Listening Text (P55)THE THINKING QUILTZoe newman, a talk-show host on Capital Radio, is talking to Mr Xiao Feng about his new invention.
ZN: Hello, everyone. I heard, Mr Xiao Feng, that you have invented something thatll be really useful in everyday life. XF: Yes, indeed. Its a bed quilt that thinks. It changes according to the humidity in the air. If its hot, it cools you down and if its cold, it warms you up.
ZN: How does it do that?XF: Well, the fibers in the quilt sense the humidity or the amount of water vapor in the air. This is a reliable guide to the room temperature in Beijing. Very little humidity generally means its cold. So the quilt fibers become bigger
and fill the quilt. They trap the air and produce a very thick, warm cover for the person in bed. ZN: So you mean the fibres can measure the amount of water in the air and then change and become larger?XF: Yes. They actually grow thicker and spread out.
ZN: So you have to wait for the humidity to change before your quilt will cool you?XF: Right! As the humidity rises the quilt fibers change again. They gradually lie flatter in the quilt. The air leaves and the quilt becomes thin and light. So its cooler in bed. ZN: Is it heavy?
XF: No. We made the material especially light.ZN: It sounds wonderful! But will it work everywhere in the world? Could you sell it aboard?
XF: Ive thought about that and I dont know. I really need some help. It will clearly be very useful in North China because Its cold and dry in winter and hot and humid in summer. But it may not be the same in America, Europe or Canada.
ZN: I was wondering about Africa and the Caribbean.XF: Maybe your listeners have some good ideas. If they do, perhaps they would like to get in touch.
ZN: Oh, yes. Please contact us if you have any ideas. Meanwhile look out for the thinking quilt in your nearest department store [voices fade out]
Listening (P59) Students work in pairs to discussion: 1. Suppose you live undersea and happen to come across disaster().What should you do?2. How will you deal with the problems that you meet, if you are the designer of the undersea city?
True or False:1. The problem happened about two months ago.2. The air machines were making a very loud noise.3. The solid steel doors to the city was open and the backup system worked well.FFF
4. A screen broke during an undersea storm and stopped the machine.5. At last the designer solved the problems. 6. The families had plenty of stored oxygen, so they did not noticed that there was something wrong with their city.TTT
Screen broke during an undersea stormReplaced screen.
Problem with the air machine.Repaired air machine so the doors worked again.
DANGERS OF UNDERSA LIVINGLi Qiang is interviewing the designer of Saturation City, William Lee, about how he saved Saturation City from disaster.Listening Text
LQ: When did this problem happen?WL: About three months ago. The first families had moved in and I was just going to check that they had everything they needed.LQ: And what was the first thing you noticed?
WL: Well, when I stepped off the shuttle-submarine the air machines should have been making a very loud noise but they werent.LQ: So that was your first hint something was wrong?
WL: Yes. Then I found the solid steel doors to the city wouldnt open. However, even then I wasnt too worried as there is a backup system in case things go wrong. When that didnt work either, I realized we had a big problem.
LQ: Did you tell the families straight away?WL: No. first I looked at the air machine to see if I could repair it. Almost immediately I found the cause of the problem.LQ: What was it?
WL: A screen broke during an undersea storm and stopped the machine. Luckily I had another screen in my tool-box. I quickly fixed it so the air machine was as good as new.
LQ: Did it solve the problem?WL: Yes, fortunately it did. When I repaired the air machine the doors began to open. Of course I went inside to check on the families. They were fine. They had plenty of stored oxygen and had not noticed anything.
LQ: And for what you did, they made you a hero?WL: Yes, they did. But I think it was really because it made them feel safer in the city. They knew people were there to look after them.
LQ: Well, thats a very modest answer. I think they recognized your devotion to duty.Thank you and goodbye, Mr Lee, medal holder of the Red Star, First Class.
