Evans Wadongo was from a village of Africa. He had to do homework by the light of a kerosene lamp (煤油灯). Evans’ eyes hurt and this made studying difficult. It was common in his village. Many children left school for this reason, so they remained poor for the rest of their lives.
Although studying was difficult, Evans was an excellent student and went to a university. He continued to worry about the kerosene lamp. By this time, he realized it was not just bad for schoolchildren but for the whole family. First, it can cause illnesses such as coughs. Also, the light can hurt people’s eyes. Besides, it can lead to fires. Lastly, kerosene is expensive, so families have less money for food. It was difficult to come up with a different kind of lamp that was cheap and good for the environment. Yet Evans did not give up.
One day, he had an idea. He could use a small solar (太阳能的) light. Sunlight is free and solar power is good for the environment. Evans built his first solar lamp, and it worked. He began to build more lamps and sent them to local families. An organization heard about this and provided money for him to build more solar lamps.
Each lamp only cost $20. However, this was a lot of money to many villagers, who only earned around $34 a week, so Evans made sure he kept the cost down. First, Evans used recycled materials. Next, volunteers built the lamps. At last, people from many countries gave away money to his team, so the lamps were usually free.
Thousands of people had safe light. Julia, a mother of three, said, “Thanks to Evans, my children have light to read, and I have my own light to cook.” The solar lamps made a big difference.

【推荐2】Somebody is calling for help in the water. You want to jump in and save him or her, but that might put you in danger. What will you do?
Soon this won’t be a problem anymore because a robot swimmer called Swumanoid will be on hand to help.
Scientists from Japan designed(设计) this robot to swim like an Olympic swimmer. They mapped(绘制) a swimmer’s body and looked at how every part of the body moves while swimming. The robot can swim just like a human does.
Swumanoid can swim the backstroke(仰泳) and the front crawl(自由泳) at a speed of 0.64 meters a second(秒), about one-third of the world record speed for these swimming styles, according to the Daily Mail.
Motomu Nakashima, head of the team that designed the robot, hopes that robots like Swumanoid can serve as lifeguards(救生员) in the future.
Besides saving lives, Swumanoid can also be used in swimming research. It can test water resistance, which makes it move more slowly. And it helps to find out how people swim. The information that it collected could help scientists find ways to improve a swimmer’s skills.
Unlike human swimmers, robots don’t get tired from doing the same stroke(泳姿) again and again, so they do not slow down. Therefore(因此), they can collect information more efficiently(有效地).
But the robot is not yet ready to take the place of human lifeguards. Scientists say there are still certain things that need to be improved.
1. Who designed Swumanoid?
A.Scientists from China. | B.Scientists from Japan. | C.Scientists from America. |
A.味道 | B.成分 | C.阻力 |
A.it can do many kinds of strokes |
B.it can swim at the speed of 0.64 meters a second |
C.it won’t feel tired and never slows down |
A.There are two uses for the robot swimmers mentioned. |
B.Swumanoid can swim the backstroke as fast as the world record speed. |
C.Swumanoid has taken the place of the human lifeguards in Japan. |
【推荐3】In the future, people may travel to Mars by water-powered spaceship! Today’s spaceships are fine for getting things into space, but they are not so good at travelling long distances. These spaceships burn chemical fuels, and they are very expensive. Scientists say that a water-powered spaceship could make the trip to Mars much cheaper. The idea is just in the planning stage now, but scientists think such a spaceship could be developed soon.
The key to the water-powered spaceship is the engine. Regular engines push spaceships by burning fuel. The water engine will use steam, created by solar panels that heat water to a high temperature. Of course, the spaceship will have to carry a lot of water for the long trip to Mars. Today’s spaceships could not carry that much water. But scientists think that a spaceship blown up like a balloon will be able to.
One company has already developed a spaceship like this. These spaceships are made of a strong material. Two of them have already been sent up into space, using rockets and then later filled with air. “Balloon” spaceships could be very large and carry enough water for a long trip. With the “Balloon” spaceships, enough water could be carried to power the engines and grow food during the trip. And the people on the spaceship might even get to take a hot bath!
Scientists say the biggest advantage of such a spaceship would be cost. The “Balloon” spaceship uses water to push it through space and costs about one thirtieth of a normal spaceship. Such savings naturally encourage continued research into balloon spaceships and water engines. If these scientists are correct, we may soon be on our way to Mars in a spaceship powered by water.

【推荐2】About ten years ago, when I was a student at college, I spent my summer holiday in a museum as a volunteer. Life was hard for me then because Dad lost his job and Mum was sick in bed. I was worried. I didn’t know if I would be able to go on with my study the next term. I felt sad every day.
One day when I was working, I saw an old man come in with a little girl in a wheelchair(轮椅). As I watched this girl carefully, I found that she had no arms or legs. She was wearing a white dress and she also had a hat on. As the old man pushed the wheelchair up to me, I was busy with my work. I turned my head to the girl and gave her a wink (眨眼). When I took the money from her grandfather, I looked back at the girl. The girl was giving me the prettiest, largest smile(微笑).
I had never seen that kind of smile before. Suddenly(突然), her handicap(生理缺陷) disappeared (消失) and all I saw was this beautiful girl. Her smile almost gave me a new understanding about life. She made me realize the meaning(意义) of smiles, love and warmth(温暖).
I’m now a successful man. When I am in trouble, I often think of the little girl’s smile.

【推荐3】Once a man’s ship broke into pieces on a small, lonely island. There was no one living on this island, so he hoped that someone could come to save him. Every day he watched the sea, but no ships ever appeared. The man grew sad.
He thought he should do something to save himself. He built a little house out of wood to live in. But one day, after looking for food, he arrived home to find his little house on fire. The smoke rose to the sky. And everything was lost. He was full of sadness and anger. “God, how could you do this to me?” he cried.
Early the next day, however, he was awakened by the sound of a ship. The ship was nearing to the island. It had come to save him.
“How did you know I was here?” the man asked these people. “We saw your smoke signal,” they answered.
