6、 a quilt which thinks. ZN: Really? XF: Well, not really! But it can change its thickness according to the temperature.,ZN: How does it do that? XF: This quilt has a tiny sensor and air pump inside. It will make adjustments according to changes in temperature. When the temperature is higher, part of
7、the air inside will come out and the quilt becomes thinner and feels cool in bed. When the temperatureis lower, the quilts takes in more air,and becomes thicker. As a result, it gives a thick, warm cover for the bed. ZN: Are there any problems with it? XF: Only one. You must remember to take the sen

11、t uses the heat from your body to attract water vapor from the air. S2: Isnt that a little uncomfortable?,S2: No. We thought about that. We gave the material a special coating to keep water away from the skin and to store it in the fibres. When they are full of water the shirt begins to clean itself
12、. S1: How does it do that? Is there soap powder in the fibres too?,S2: Not really, but we thought the fibres could do that job if they had a special anti-pollutant in them. It mixes with the water and removes the dirt from the shirt. The dirt is then carried into the air as the water turns back into
13、 vapor. S1: How will you know if the shirt is doing its job?,S2: If the shirt is working well it will appear white. When the shirt is blue, itll mean the shirt is too old and isnt working properly. Itll also mean its time to throw it away. We think all our shirts should be able to deal with any leve

28、ich four parts make up the upper part of the Saturation City?,The floating island includes 4 parts as followed: a hotel with many rooms for families to relax while their bodies return to normal; a large classroom with all kinds of educational aids for children of school age; a huge sports stadium; a
29、 very big hall for entertainment.,This passage is written in the style of an advertisement to sell houses under the sea. As people are not used to living under the sea, the company must encourage people to move there by giving them some extra advantages.,Writing Style,The aim of this task is for stu
30、dents to imagine what it would be like to live under the sea: its advantages and disadvantages.The name, Saturation City, comes from science. After people have stayed for some time under the water they need to come up to the surface.,They are “saturated” or have stayed as long as their health will a
31、llow. At the moment it is difficult to stay for one full day under water except under special conditions. In Key Largo, Florida, scientists have devised an undersea laboratory, which means that people can live and work under water for up to ten days at a time before returning to the surface.,By the
32、year AD 3008 it will undoubtedly be possible to stay under water even longer.Living underwater is similar to going into space. Both affect the human body badly. In space, the lack of gravity makes a person grow taller and his/her bones become more brittle.,Under water, the pressure pressing down on
33、the person is too great. So, people living underwater have to come back up to the surface to restore their bodies to normal. In the reading, three man-made islands have been provided for this purpose for the people of Saturation City.,People are asked to move and live under the sea in AD 3008. It is
34、 assumed that the population on earth has become so great that it is impossible for them all to find a place to live on land. Perhaps global warming has melted the ice in the North and South Poles and raised the sea level.,If that were the case, the land would be needed to grow food for the growing
35、population.,These four parts provide the necessary “home space” for families on their regular leave so that no island is too crowded and everyone gets a break from underwater life.,Whats the purpose of building these parts?,1. Who has the right to go to the education part? 2. When will the education
36、 part be open to the people? 3. Where will the education part be built? 4. What kind of service will you provide? 5. What problem will you come across?

37、ow you think it will help),Structure,A sample version,The wonderful facilities in the sports stadium of No.3 Floating Island, Saturation City, means that the company can offer a full programme of sports. There are coaches for all areas of sport so that everyone will be able to improve their health.,
38、All sports are offered. There are opportunities to improve skills in running and all field events, high and long jump, swimming, and throwing events. There is also a fully equipped gym for exercise and gymnastics.There are two kinds of coach: specialist ones to improve a particular skill to internat
39、ional level; general,ones to improve fitness and encourage healthy exercise. Both kinds of coach are available at all times for those who live in Saturation City. The fitness programme is intended to encourage personal improvement. The specialist programme is intended for competitions (which will be
40、 held once a month).,The winners in each event will have to enter the trials for the Olympic Games in AD 3008 which will take place in the Sahara Desert, North Africa.We hope that you feel that these facilities and programmes will help raise your fitness level and specialist expertise.

45、interviewing the designer of Saturation City, William Lee (WL), about how he saved Saturation City from disaster.,Listening Text,Part 1 LQ: What happened? WL: Well, about three months ago I was doing my monthly check on the gates when I noticed something strange. LQ: What did you notice?,WL: It was
46、too quiet. When I stepped off the shuttle-submarine the air machines should have been making a loud noise but they werent. LQ: So was that your first feeling that something was wrong?,WL: Yes. Then I found that the solid steel gates to the city wouldnt open. At first I wasnt too worried as there is
47、a backup system in case things go wrong. When that didnt work either, I realized we had two serious problems.,Part 2 LQ: Did you tell the families in Saturation City? WL: No. I examined the air machine to see if I could repair it and almost immediately I found the cause of the problem. LQ: What was
48、it?,WL: A screen broke during an undersea storm and stopped the machine. Luckily I had another screen in my toolbox. Oncefixed, the air machine was as good as new.,LQ: Did it solve the problem? WL: Yes, it did. As soon as I repaired the air machine, the gates began to open. Then I went inside to che
49、ck on the families. They were fine. They hadnt noticed anything wrong.,LQ: And now youve been made a hero? WL: Yes. But I dont feel like one. Its my job to make them feel safer. LQ: What a modest answer! I think they appreciated your devotion to duty. Thank you and goodbye, Mr Lee, medal holder of the Red Star, First Class!,
