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.

    THE HISTORY OF LIVING IN SPACE

    Space travel is nothing new. The first spacecraft with a human on board blasted into space In 1961. since then, people have not only been travelling to space, but many of them have also lived there for extended periods.

Food

    All the meals on space stations are put together on Earth and sent to the space station, along with the astronauts, by space shuttle. Because the food has to last a long time (sometimes up to three months), a lot of it has to be preserved by dehydration or canning.

    The space station does not have a freezer to preserve food, but It does have a cool room to keep fruit and vegetables fresh.

Astronauts also eat many other foods such as cereals, cereal bars, nuts and dried fruit that do not need any special preparation.

    Eating

    Astronauts have a set timetable each day. This tells them when to do everything, including when to have their meals. At meal preparation time, they start getting their food ready, which often includes adding water to re-hydrate the dehydrated foods.

    Without the help of gravity, sitting down to eat can be tricky. Astronauts sometimes have to strap themselves and their food into place. Because of lack of gravity, astronauts cannot use ground salt and pepper, and all drinks must be taken from bottles. They also have to be careful that crumbs do not fly off and get stuck in vents and instrument panels.

Dear Li Ping,

    How are things with you? It was great talking to you yesterday by phone. As I told you yesterday, I am in Jiangsu today. Tomorrow we are getting the train down to the south of the country and then a ship across to Shanghai.

    Let me tell you about the places we have visited so far. I know you want to come here on vacation one day! We started in Zibo and we spent two days in Jinan. We visited many different places and enjoyed lots of things. And the only bad thing was the weather- it rained the whole time when we were there. Can you believe it?

    At least when we got to Jiangsu, the sun was shining! We only stayed for one afternoon in Jiangsu because my friends really wanted to visit Disneyland which is in Shanghai.

    I bought you a surprise gift here. I hope you will like it. OK. That's enough from me for now. I want to post this letter now so you can get it by the weekend.

    See you soon!

Ma Hua

    Some people from the country think that city life is the most interesting. They come to visit friends or go to a hotel in the city. They may stay for a few days or as long as a week.

    Some visitors think that foreign restaurants are the best part of city life. Others have the nicest time in museums. But many people think that movies or concerts are the most important attractions of the city. And most visitors like to go shopping for clothes or presents.

    In the city there are also many parks, different types of people, tall buildings, and other interesting things to see. Cities have the busiest streets and city life seems very busy, too.

    After a few days in the city, the visitors begin to think about the country. They remember the trees and flowers. Suddenly they do not want to be near the tallest buildings or the busiest streets. Now they want to return home in the country.
