The Milu deer is a kind of animal with large horns(角). They were very common in China long ago. They lived together and ate grass and the soft parts of trees. In the past, people did not protect the Milu deer and killed them for food or sport, so they disappeared(消失) from China .

      Luckily before all of them disappeared, the Duke of Bedford(贝德福特公爵) took some to Britain. The Milu deer like the cool, wet weather in England and their numbers increased(增长) year by year. As a result, when in1985, the government of China wanted to bring back the Milu deer, the Duck of Bedford was able to help. The first deer came back to China to the Nanhaizi Milu park near Beijing and to Dafeng, Jiangsu Province.

      Since they returned to China, their number has grown quickly .There are now so many of them that a new park has been opened for them in Hubei Province. Now the Milu deer live in the wildlife parks and have good protection. We hope that one day they can live in the wild again.

    Earth Day is on April 22^nd. People say thanks to the Earth and learn ways to keep the Earth safe and clean. But saying the Earth is not just for grow-ups. Kids are also taking an active part in it.

    The American writer and filmmaker Lynne made a film called Young Voices for the Planet. It lists a lot of stories about different kids who help to keep our environment clean.

    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 (垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used (被使用) again.

    ◆No—car day. On a no-car day, nobody comes to school in a car—not the students and not the teachers! Cars give pollution to our air, so remember: Walk, jump, cycle or run.

    Use your legs! It's lots of fun!

    ◆Turn off the water! Did you know that some toilets can waste (浪费) twenty to forty tons of water an hour? In a year, that would fill a small fiver! In environment clubs, students mend those broken toilets.

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

    Today many people like growing plants at home because the plants help make the indoor environment beautiful and healthy. However, sometimes people may be too busy to remember to water their plants. If you have the same problem, don't worry. Designer Alastair Crompton can help you solve the problem with his amazing product-Plant Pod. It can water itself without any help.

    The Plant Pod is a self-watering container (容器) for small to medium-sized plants inside the house. Alastair Crompton makes it use a very simple process to provide the plant with the water it needs every day. With a Plant Pod, people no longer need to worry about how much water is perfect for their plants to grow. The water in the Plant Pod is enough to last for at least two weeks. So if people are away from home on a short holiday, they don't need to ask their relatives or neighbours to look after their plants. Won't it be great to see your plants welcome you when you are back home after one or two weeks?

    Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big. And they can eat small animals. One famous meat-eating plant is the Venus flytrap(蝇草).

    The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly (苍蝇) touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.

    Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn't have all these important things, especially nitrogen(氮).Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let's hope that some of the bigger plants don't get the same idea!
