A Nepalese teenager had made a £ 23 solar panel (太阳能电池板 ) using human hair.
Milan Karki, who is 18 years old and lives in a village, used human hair to replace (代替)silicon, which is a common but expensive part of solar panels. By using hair as a replacement, Karki says that solar panels can be produced for around £ 23.
Karki got the idea from a Stephen Hawking book, which explained how to create energy from hair. The device (设备) that Karki has showed can produce 18w of energy -- plenty to charge a mobile phone.
"Half a kilo of hair can be bought for only 16p in Nepal and last a few months; but a pack of batteries (电池) would cost 50p and last a few nights," according to The Daily Mail.
The solar panel is easy to service as the hair is easy to replace. Karki has now sent out several devices to other places near his home for testing. He said, "First I wanted to provide energy for my home, then my village. Now I am thinking for the whole world."
【小题1】 Karki wanted to use human hair because it is

| A．为……改变 | B．为……付款 |

Walking is a popular form of exercise. It is an easy activity and offers a good way to improve physical fitness. Walking also gives many of the same benefits as other kinds of exercise.
Regular, brisk walks help a person's body work better. Walking builds a stronger heart and lungs. Walking also seems to help protect the heart from heart disease. The lungs work better because they take in and use oxygen more effectively. Walking can help in weight control, too. A quick fifteen-minute walk burns as many calories as jogging the same distance in half the time. Walking causes very injuries, so there is also a lower "dropout" rate among walkers than among runners.
People are more likely to continue a walking program. This gives a better chance for success. Walking offers some mental benefits, too. It seems to make people feel better. Many walkers say they sleep better at night when they take regular walks. Others say they have a better attitude towards life. Walking offers many of the same physical and mental benefits as other forms of exercise, but walking offers some special advantages, too. Almost everyone can walk. There are no special lessons or training. To become a real walker, a person only needs to walk faster, farther, and more often.
People can walk almost anywhere. There are no special playing fields or courts for walking. Sidewalks, streets, parks, fields, and malls are excellent places for walking. People can walk almost anytime. A person doesn't need a team or a partner for walking. There is no "season" for walking. Most walkers walk in all kinds of weather.
Walking doesn't cost anything. There are no special fees for walking. Good walking shoes and comfortable clothes are the only equipment that a walker needs.
Walking offers a form of exercise within the reach of nearly everyone. With a little time and effort, people can rediscover a valuable form of exercise and improve their fitness.
【小题1】Walking benefits people's_______.
| A．legs and arms | B．feet and hands |
| C．heart and lungs | D．head and stomach |
| A．it is easy to continue |
| B．it is funny |
| C．they are ill |
| D．they want to see who walks faster |

任务型阅读 阅读短文，按要求完成各题。（5分）
At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the planet Mars. Our own planet, Earth, is becoming more and more crowded and polluted. Luckily, we can start again and build a better world on Mars.
First of all, transport should be much better. At present, our spaceships are too slow to carry large numbers of people to Mars—it takes months. However, by 2100, spaceship can travel at half the speed of light. It might take us two or three days to get to Mars!
Secondly, humans need food, water and air to live. Scientists should be able to develop plants that can be grown on Mars. These plants will produce the food and air that we need. However, can these plants produce water for us? There is no answer now.
There is a problem for us to live on Mars. Mars suck us much less than the Earth does. This will be dangerous because we could easily jump too high and fly slowly away into space. To prevent this, humans on Mars have to wear special shoes to make themselves heavier.
Life on Mars will be better than that on Earth in many ways. People will have more space. Living in a large building with only 10 bedrooms is highly possible. Many people believe that robots will do most of our work, so we have more time for our hobbies.
There will probably be no school on Mars. Every student will have a computer at home which is connected to the internet. They can study, do their homework and take exams in online schools. Each student will also have their own online teacher called “e-teacher”.
However, in some ways, life on Mars may not be better than that on the earth today. Food will not be the same—meals will probably be in the form of pills and will not be as delicious as they are today. Also, space travel will make many people feel ill. The spaceship will travel fast, so the journey to Mars will probably be very uncomfortable.
