Do you know a kind of bird called tawny owl? Where does it come from? It comes from Finland (芬兰). What color is it? It is brown. Are all the tawny owls brown? No. Tawny owls come in two colors: pale gray and brown. And in Finland, it often snowed in winter. Many tawny owls were pale gray. But as the Finnish (芬兰的)winters get warmer, there are more brown ones. Why is that?

    The University of Helsinki team tries to study tawny owls. They find that tawny owls get the color from their parents. The gray owls could get food easily in the snow in the past. But now the winter is warmer. There is little snow so the brown owls can live well, too. The number of the owls is getting bigger.

    The leader of the team, Dr Patrick Karell, said that the birds change their color to meet the weather. We are sure the weather change can do something to the animals.

    In most parts of the world, many students help their schools make less pollution．They join environment clubs．In an environment club, people work together to make our environment clean．

    Here are some things students often do．

    No-garbage lunches．How many lunch bags do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again．Every week they will choose the classes that make the least garbage and report them to the whole school．

    No-car day．On a no-car day, nobody comes to school in a car including the students and the teachers．Cars give pollution to us, so remember:

    Walk, jump, bike, or run!

    Use your legs! It's lots of fun!

    Turn off the water! Do you know that some toilets can waste twenty to forty cubic meters of water an hour? In a year, that would fill in a small river. In the environment clubs, students mend those broken toilets．

    We love our environment．Let's work together to make it better．

    Have you ever stood beside the ocean and stared at the waves (波浪)? The way they move is changing! Nothing is more peaceful than watching the movement of water.

    Every ocean has waves. Unless you are lucky enough to live by the sea, though, you probably can't watch the waves very often. How would you like to have your own wave machine? Making one is easy and a lot of fun.

    Now that you have made your ocean, put your bottle on its side. Wait a minute. The water win be on the bottom. The oil and paint thinner mixture will be on the top. Now tip (倾斜) the bottle back and forth (反复来回) and watch the waves.

    There are millions of different animals in the world, but some are in danger, and some may soon die out. People can never see them again. Mark and David wanted to find some of these rare animals, so they climbed mountains, crossed rivers, and walked through rainforests.

    A Bat, a Cat or a Squirrel?

    Mark and David found the aye-aye. The aye-aye has bright eyes. It has ears like a bat, a body like a cat and a tail(尾巴) like a squirrel. Some people think the aye-aye brings bad luck. They killed(杀死) many of them, and cut down a lot of trees where the aye-aye lives as well.

    A Strange Parrot

    Mark and David found the biggest parrot in the world that cannot fly. Many years ago, some animals came to the place the parrots lived in, and killed many of them. Now there are only a few left.

    Another Special Animal

    Mark and David went looking for a manatee. A manatee looks like a seal and a hippo. In some places where manatees live, the water in the river gets low. Then the manatee swims to the place where there is more water. Many get stranded(搁浅), and some are killed by other animals and people, too.

    After Mark and David returned, they made a film about these animals. They want to show the world these strange but interesting animals. They want the world to know there are not many of them left, and they all have a place in our world.

    China isn't well known for its science fiction films, but recently a new film called The Wandering Earth has become a great success. It has earned over $697 million worldwide. It tells an amazing story of the Earth in danger, along with exciting scenes of spaceships and outer space.

    The Wandering Earth is based on a story by Liu Cixin. In the story, the sun was dying out, people all around the world worked together to move Earth out of the solar system and sail Earth to a new star system. The film began with the early life of a young boy who was born just after the project started. The engineers pushed Earth away and built underground cities that were vast enough for all the other humans to live in. Yet the 2500 years' journey came with all kinds of dangers. In order to save the humans, a group of young people came out and fought hard for the planet.

    China is playing an increasingly important part in the film industry. Its growing middle class has seen the rise of film market across the country, and Chinese viewers have become an important part of film industry. Hollywood Projects like Iron Man 3 specifically filmed more scenes in China for its market. Chinese film industry is keeping growing. Just as Americans want to get into the Chinese market, Chinese filmmakers are looking for the way to the international market.

    According to The Hollywood Reporter, The Wandering Earth is China's "first space" film. Chinese science fiction writer, Anna Wu, says science fiction "is a new challenge for the Chinese film industry." Some Chinese filmmakers have achieved a great success at this kind of film, but most of them still have a long way to go.

    Still, Wu notes that within China, "Not all the science fiction films have had success. It still takes time to accept science fictions, and that with the development of our country, people are getting busier, wealthier and more stressed," which creates a perfect environment for this new kind of film and television. The Wandering Earth, she says, is a good example. "I also care about the money it earns, which will affect the future of Chinese science fiction films."
