    Rivers are one of our most important natural resources(资源). Many of the world's great cities are located on rivers, and almost every country has at least one river through it that plays an important part in the lives of its people.

    Since the beginning of history, people have used rivers for transportation. The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Ganges is great, but it is also important for transportation. Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeastern Asia. The greatest of all for navigation(航海), however, is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles up it.

    Besides transportation, rivers give food, water to drink, water for crops, and chances for fun and recreation for the people who live along their banks. In order to increase the supply of water for crops, engineers sometimes build a dam(坝) across a river and let a lake form behind the dam. Then people can use the water not only to irrigate(灌溉) their fields but also to make electricity for their homes and industries.

    However, large cities and industries that are located on rivers often cause problems. As the cities grow in size and industries increase, the water in the rivers becomes polluted with chemicals and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits of them.

    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.

Another Disney princess movie hit theatres on 5th March 2021. But this time the princess doesn't wait for the prince to save her — she is ready to save the world herself. Raya and the Last Dragon, the film shows Southeast Asian culture and Disney's first Southeast Asian heroine (女主角).

The story takes place in a world called Kumandra. Five hundred years ago, the world's dragons died to save humans. But the world breaks up into five states and they fight against each other. Raya, the princess of one of the states, needs to find the last dragon to save the world. On her journey, Raya invites other people to join her and learns to trust others and be more responsible.

Once upon a time, being a Disney princess meant being a damsel in distress(落难女子) in a European fairy tale, but this movie is different, according to the BBC. Raya has no boyfriend, but is a great fighter who is very brave and independent, according to the movie's writer Adele Lim.

Besides Raya, most of the main characters in the movie, including the dragon Sisu, are female. They stand out and depend on(依靠) no one else instead of acting as supporting roles for males. Namaari, once a friend to Raya, is now a dangerous enemy. She is a strong, brave and loyal fighter, just like Raya.

The movie shows "a complicated dynamic(复杂互动) that's still rare in the Disney universe, particularly between women," the Los Angeles Times said.

Whenever the exam season comes, stress may come along. Here are some ways that have helped me and my friends through this season. 

When the stress of exams is really hitting me, I stop and take a walk. I usually borrow my neighbors' dogs and walk for about fifteen minutes. Many boys would simply choose to run for a while, or play ball games. Having some sports drives away your stress easily most of the time. 

And if you find music helpful, give it a go. Listening to your favorite songs will surely make you happy. The best thing about this is that you don't have to go anywhere. 

But if you are a book lover just like me, read a book you like for half an hour. Reading can take you to places you've never been to. Putting yourself into a new world helps you forget your stress in this world for a little bit. 

For sure, laughing is the best medicine. It can really keep worry off your mind! Very often I call my best friend and we talk about our good time or something funny, and I'm feeling better than before. 

Remember many others also face the problems of stress just like you, and it is not something that cannot be dealt with.
