【推荐2】Upcycling is the process of changing old materials into something useful and often beautiful. It is different from recycling. When you recycle something, old materials need to be broken down so that their base materials can be remade into a new product, often of inferior（次等的）quality. When you upcycle an object, you aren’t breaking down the material. You’re simply making it into something else. Also, the upcycled object is typically of the same, or even better quality.

The idea of upcycling isn’t new. Some of the best examples of modern-day upcycling come from the 1930s to 1940s when people didn’t have many material resources（资源）. In those days, people found new purposes for old things over and over until they were no longer useful. For example, old coats would be turned into shoes and an old door would be made into a new table.

Nowadays, saving is still a big reason why some people upcycle. An even bigger reason for the rebirth of upcycling is that it’s environmentally-friendly. Things shouldn’t just be thrown away when they can be turned into something useful. Upcycling is also more environmentally-friendly than recycling which requires energy or water to break down materials. Upcycling just requires your own creativity and effort.

Upcycling can provide you with something that’s both creative and practical. Why don’t you support the idea by checking your house or recycling bin and creating objects yourself? Take action right now!

Every school day, we use schoolbags to carry all of our things to school.    1    But have you ever thought about the history of the schoolbag?

In the Han Dynasty, when old-style private schools were opened, students used bamboo boxes to carry books to school.    2    . There were usually two or three layers（层）in the box. Kids put different things, like books, brushes, ink stones （砚）and paper in the boxes.    3    .For example, in The Legend of White Snake, Xu Shilin caries a bamboo box to the capital to take an exam. And in the movie The Chinese Ghost Story（倩女幽魂），the scholar Ning Caichen also carries a bamboo box.

Hundreds of years later, people developed a new kind of schoolbag called the budai, or “hip-pocket”. The budai was lighter than the bamboo box. With the founding of the People's Republic of China, military rucksacks （军用帆布包）became popular.    4    Maybe they can tell you about their experiences of carrying them when they were in school.

A new style of schoolbags has been produced in recent years. Many of them have colorful and fashionable designs on them, such as pictures of cartoons or pop stars. And they are more comfortable to use. Some students pull wheeled bags filled with heavy textbooks and others carry backpacks    5    .

Schoolbags are still changing. Can you imagine what schoolbags will be like in the future?

A．Everyone at that time owned such a bag.

B．You can see the bamboo box in many TV shows.

C．We can't go to school without our schoolbags.

D．People consider the bamboo box to be the earliest schoolbag.

E．They are the most common seen schoolbags now.

F．They are a big part of our lives.

G．Ask your grandparents or parents about these bags.

【推荐1】Wukong, Tiangong, Tianwen…Do you know where the names of Chinese space programs come from?

Wukong, the Dark Matter Particle Explorer satellite (暗物质粒子探测卫星), is named after Chinese superhero of Monkey King. According to Journey to the West, Monkey King has a pair of sharp eyes which can tell the difference between good and evil. The Wukong satellite is just as sharp-eyed as Monkey King to help scientists search for dark matter in space.

The name of the space station, Tiangong, means “Heavenly Palace”. In Chinese myths, this is the home of Tian Di. Now Tiangong Space Station is a home for Chinese astronauts in space. And China welcomes foreign astronauts to Tiangong so that they can work together.

Tianwen, China’s Mars missions (任务), gets its name from the poem Tianwen by Qu Yuan. Qu Yuan is a well-known poet from ancient China. In Tianwen, he had the questions about the sky, stars, nature, myths and the real world, showing his hunger for truth. Perhaps the Tianwen missions will end up answering some of Qu Yuan’s questions.

If you look into more names of Chinese space programs, you will find that they all have beautiful meanings. We, the Chinese people, have a long space dream. So the naming of Chinese space programs is treated very importantly.

1. What is the Wukong satellite used for?

A．Answering some of Qu Yuan’s questions.

B．Finding the difference between good and evil.

C．Helping scientists search for dark matter in space.

D．Welcoming foreign astronauts to the space station.

2. What does the underlined word “myths” in Paragraph 3 mean in Chinese?

A．成语

B．神话

C．谚语

D．传记

3. The name of China’s Mars missions is from ________.

A．Qu Yuan’s poem Tianwen	B．a Chinese traditional story
C．ancient Chinese myths	D．a novel called Journey to the West

4. Why do Chinese people treat naming of space programs importantly?

A．Because we want to land on Mars.

B．Because we have a dream for space.

C．Because we want to protect the earth.

D．Because we have the hunger for truth.

【推荐3】Sending astronauts to Mars is a big challenge. Astronauts will have to ate everything they need, including food, air and water. The room inside the spaceship is too limited to hold many things. So packing a spaceship is a huge challenge for a trip to Mars.

Six astronauts on an eight-month tip to Mars will need at least 18,000 kilograms of water for drinking and washing. They’ll also need water to protect themselves from space rays which can pass right through spaceship walls and harm astronauts’ living cells. But a layer of water placed around the ship can stop the harm.

That’s a lot of water. And sending water into space is too expensive. It costs $33,000 to send one cup of water to Mars. The more you take, the more it costs. We have the technology to get to Mars, but the problem is that it’s too expensive.

But Flynn, an engineer at NASA, thinks he has a way of solving the problem. Instead of building a heavy spaceship and packing it full of stuff (物料), why not use the stuff as part of the spaceship?

Imagine a spaceship that blows up like a balloon. Inside, the walls have pockets like a big honeycomb (蜂巢). These hold lots of plastic bags filled with water, dried food and algae. All these make hard walls and great radiation (辐射) protection. And stopping radiation does not influence the food or water itself — it is safe to eat and drink. And what if the same water could be reused again and again? Flynn and his team call their packed-pocket idea Water Walls.

Making oxygen and taking away CO₂—the waste gas you breathe out—is another problem in space. “Water Walls will take away CO₂ the same way it’s done here on our Earth—with living plants,” Flynn says. Living plants make in CO₂ to make their food, and give off oxygen. “Plants are hard to grow in a spacecraft, so we use algae,” he says.

Algae are tiny plants that live in water. The algae will live in bags in the walls too, fed by human waste and sunlight, eating up CO₂ and making oxygen for the astronauts to breathe.

Flynn thinks his onboard recycling system has many advantages. He hopes it will help make flying to Mars a reality very soon.

A．To produce water in the spaceship.

B．To make the whole spaceship stronger.

C．To prevent space rays during the space trip.

D．To control the temperature in the spaceship.

4. Why are algae put in the plastic bags?

A．To serve as food for astronauts.
