How green are you ? Do you know how to be green?

    We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.

    Reduce

    Reduce means “use less”. Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.

    Reuse

    Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It's better to use a china cup and a lunch box because you can use them again.

    Recycle

    Recycle means “change things into something else”. Though it takes energy(精力) to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighborhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

So please remember these three words： reduce, reuse and recycle.

    Zhalong is a nature park in Heilongjiang in Northeast China. It is one of the world's most important wetlands. The area provides food and homes for wildlife. It is an ideal home for different kinds of plants, fishes and birds.

    Many birds live comfortably in Zhalong Nature Park all year round, while some only stay for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong Nature Park is an important living area for the rare red-crowned cranes. There are not many red-crowned cranes in the world. Some of them live in Zhalong.

    Some people want to change the wetlands to make more space for farms and buildings. This means that there will be less and less space for wildlife.

    More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered birds, and they can be safe in Zhalong.

    Every year a lot of tourists go to Zhalong to watch birds. This year members of our Bird Watching Club are going to study the different kinds of birds in Zhalong and the changes in their numbers. The study will begin next month.

    We do a bird count once a year. We are now inviting the second school students to help. We need more people to help us count and do something to help the birds. Many people do not understand the importance of the wetlands. We hope this information will help them understand it and make them actively take action to protect wildlife.

    A long time ago, people thought that the Sun went round the Earth. In some countries people even said that the Sun was a god (神). They thought the god drove across the sky each day on a golden horse. Now we know the Earth goes round the Sun. It takes the Earth a year to go all way round the Sun. Today men even know how far it is for the Earth to go round the Sun. They tell us that the Earth travels over a thousand miles a minute on its journey round the Sun.

    The Sun is really a star. It is much bigger than the Earth and it is very hot. Some people have been to the Moon but we know that no one can ever go to the Sun. It is far too hot for people to live anywhere near it. The Sun is about three hundred thousand times heavier than the Earth and more than a million times larger.

Buying second-hand things is becoming more popular these days. People sell all kinds of second-hand things, such as clothing, books and electronic products (电子产品) online every day.

Some people have bought more things than they really need, according to a speech given by the founder of a second-hand book-trading app (应用程序). As many people like a simple lifestyle, they are selling their used things cheaply. Shoppers choose them because of the low price. What's more, they think using second-hand things is good for the environment.

Chen Junjun, a student in Shanghai, often uses the app to look for the books she wants, just like on other shopping websites. The difference is that the books on the app are much cheaper—as much as 70% cheaper than new books.

It's reported that lots of people like Chen often buy second-hand books. The app has over 3 million users and sells about 20,000 second-hand books every day.

Buying second-hand books can even connect (把……联系起来) readers. Zhao Kaiqi, a student in Harbin, once found a note in a second-hand book she bought. "Its previous owner shared her ideas on the note. It was so heart-warming," Zhao said. "I want to do the same thing in the future."

There are many festivals around the world. Dads have Father's Day. Mums have Mother's Day. But do our grandparents have a1 ? Yes, they do.

The Double Ninth Festival is a2 day for old people in China.

The festival is on lunar(农历) September 9th. On this day, people show 3 and respect(尊敬) for their grandparents. Respecting old people is a tradition in China. There are many ways for Chinese people to 4 their respect. When an old person enters a room, everyone should stand up. Also, people are introduced from the5 to the youngest. The old usually don't have to buy tickets for buses and young people always 6 their seats to old people on a crowded subway train or bus.

However, in western countries, old people have 7 lifestyles from those in China. They don't often live with their children, they live 8 . They don't want to get help from others. They even don't want to be offered seats by others.

Westerners 9 respect old people. For holidays, families usually 10 at the grandparents' homes. A great smile and a warm hug are enough for grown children to show their respect.
