Save the world's trees

    "When it comes tothe Earth, there is no time to waste." says the Earth Day Network. And that isright. Protecting our environment is very important, and World Earth Day wascreated in 1970 to ask more people to protect our environment. On April 22, peoplearound the world celebrate Earth Day.

Every year thereis a special topic, and this year it is "Trees for the Earth", so Earth Daythis year will be all about planting trees. They are planning to plant 7.8billion trees within the next five years.

That's a biggoal, and you might wonder why trees are so important. Because they can take incarbon dioxide (CO₂) and protect the air quality(质量). CO₂ isa chemical in our atmosphere, but humans make too much of it. Each person makesabout 2.3 tons a year, which is bad for the environment.

Well guess what!Planting new trees is important because people cut down a huge number of trees.Last year, there were 3 trillion trees in the world, about 139 billion inChina. But according to China Daily, the world's total number has been almostcut in half since human civilization(文明) began. That's because 15billion trees are cut down every year.

So we need toplant more to make up for（弥补）the ones we lost. One treecan take in 21. 8 kilograms of CO₂ per year. And it's still one ofthe cheapest and best ways to get rid of CO₂.

    But don't forget that we can also help the environment by cutting down on how much energy(能源) or water we useevery day. Every little thing helps.

    There are many kinds of 1. transportation now. Which one do you like best, by train, by bus or by plane?

A plane ticket can also be easier to book, and there are 4.(hundred) of planes leaving half an hour to everywhere. But it is much 5.(expensive) than traveling by train or by car. Many people prefer to traveling together by train. Because the train is cheaper than the plane and you can see the beautiful scenery out of the windows. But sometimes people are very noisy on the train. And it's very small and crowded inside the train. Taking a car is great. You can feel freer in your own car and you can move quickly from place to place at any time you like. 6.But sometimes you may be late because of the heavy traffic  .You have to pay for a car park and petrol . Cars are less comfortable than trains. You can't sleep or relax when you drive. Cars pollute the air more than trains, too.

    Many young people want to be famous players like Yao Ming. They think they will own (拥有) everything when they are famous. And then they will do what they want. For example, when you are famous, you can do something good for schools and charities (慈善机构). You can also do some work to help others. However, as a famous person, it is not easy. You will meet many problems. If you are famous, people will follow you everywhere. They are around you every day, but you'll never know who your real (真正的) friends are. You'll lose your own (自己的) life. In fact, many famous people are not happy. They feel that the life before was more interesting.

A Student's Card

    I used the new machine to wash the clothes. Everything worked well, but I found one of my husband's socks missing. I looked everywhere for it, but I couldn't find it anywhere.

    The next morning I got ready for school as usual. When the bell rang, the students came in. We began the class. When I turned round to write on the black-board, the class broke out a roar! They laughed and laughed. They laughed so much that I was afraid that the headmaster would be in to see this. I asked the class to stop, but the more I asked, the more they laughed. I decided to go on with my lessons and I wrote on the blackboard. When I did this, they roared even more.

    At last the teacher who had the room next to mine came in to see what had happened. When he came in, he started to laugh, too.

    "Oh, dear!" I said. "Will someone please tell me what is so interesting?"

    "God," said the teacher, "You have a brown sock on the back of your skirt!"

    So that's how I found my husbands missing sock.
