    Last week, 36 students in Linyi, Shandong Province, wore beautiful clothes in a show. Their clothes were made of all kinds of waste things.

    The show gave the students a chance to make clothes with their own hands. It also helped them learn to make good use of waste things.

    "We hope to save energy. Our world is short of energy, so I don't want to throw old things away," said Xie Jing at Linyi Art School. Xie had more than 20 CDs from her family and friends. "Though the CDs are old, I look very cool in them!" she said.

    Wang Dandan, a student from the same school, looked like a farmer in her straw (稻草) coat and hat. She picked the straws from the fields and put them all together. "I want to show what people wore in the past," she said.

    Du Yue made clothes like astronauts' clothes. Her clothes were white. When she walked, she tried to be slow. It looked like she was walking on the Moon. "I wish that I could walk on the Moon!" she said.

    Hi, everyone. I'm Tina. I think our life in 2060 will be different from our life at the moment. There will be many robots in my house. Because robots will be cheap. And these robots will help my family do many kinds of work every day. Every morning the clock-robot will ask me to get up. Then the clothing-robot will dress me quickly. Next the kitchen-robot will make breakfast for me. When I get out of the house with my schoolbag, a car-robot will wait for me. After I show it my school ID card, the car will go. And then the car-robot will check my homework. When I get to school, the car-robot will say to me "See you tomorrow, Tina. Good luck."

    In the morning, I will have three lessons with my classmates. We'll study on the Internet. We'll use the e-book. The teachers are all robots. They are in different sizes and they can answer any question about any subject. In the afternoon, we will go to science lab to have two classes in a new plane. After class, we'll play football with robots. My classmates and robots can all be my friends. Don't you think the life with robots in the future will be fantastic?

    Hi, friends!1 me! I2Africa. And now I live in a zoo in the south of China. People always3 that animals are their friends, but they don't treat (对待) us as true friends.

    Every day, many people come here to4me. It seems (看起来) that I can make them very happy. But I don't like to live here,5I don't have many friends. And people think sometimes I am dangerous, so I have to be in the same6all day. It's boring for me. And in my hometown (家乡), people7many of my friends for their ivory. They are in great8. I don't want to live here. I want to go back to nature (大自然) and9 a happy life. Do you know who I am? I'm a(n)10.

    Please come and save us.

    Can you imagine that we could build a beautiful city with rubbish? Maybe you will think it is1. However, it can be true! Nothing is a waste if we have a creative mind. Let me show you something about 2rubbish.

    Sometimes we can see tons of rubbish in the streets, on the roads, near the buildings... here and there.  Many large cities became so ugly 3 it. Nobody likes rubbish, but in fact, some rubbish can be used again. All of us want to solve the problem, we must do something to 4 rubbish. We should take action from now on. 5, some good things will not be wasted.

    Do you often throw away things you don't need any more? Have you ever thought about how these things can actually be put to good use? For Example, when a car gets too old, it may not run any more. But we can use the metal of the car to make something else. When a bottle is empty, it 6 as waste. You don't know bottle glass can be made into sand and used to build streets. Rubbish7food can be changed into fertilizer to make plants grow better. It is cheap and safe. And other rubbish can also be used to make building blocks. Now, 8machines are designed for that.

    9, people will watch films in a beautiful cinema which is built out of rubbish. Besides buildings and roads, cities may be made from rubbish. But so far, building beautiful cities made from rubbish is only 10.

    Each one of us shares this planet with seven billion others. And we all need 1. People and products need to move from city to city and country to country. However, we all know 2 most cars, motorcycles, boats and planes cause air pollution. They are also 3.This is a serious problem in many cities.4 inventors are coming up with creative ideas to try to reduce the pollution and noise.

    In many cities around the world, motorcycles are very 5. Now Vietnam has around 33 million motorcycles and China has almost 120 million. Motorcycles are a faster and cheaper way to get around a city than 6. Yet air pollution is a growing problem. In large cities, people7it is difficult to breathe. To solve these problems, a US company designed an environmentally friendly motorcycle. It uses electricity as fuel (燃料). As a result, there is 8 pollution. It's also quiet and fast. This makes 9 a good choice for getting around a city.

    The Italian city of Venice is a city with only a few 10. There are no cars in the city center,11 cars, water taxis and buses carry people along the city's canals (运河). However, they cause pollution, 12 to the water. English engineers Dick and Jim designed a solar –powered(太阳能) water taxi. The water taxi 13 run for a day after being recharged(重新充电). Planes also cause air and noise pollution. Designing an environmentally friendly airplane is a real 14. Some airplane companies have 15 to solve the problems. Swiss engineers have gone one step further. They developed a solar airplane. This plane holds the world record for the longest solar-powered flight-1,541 kilometers from Arizona to Texas in America.
