If you want to find out a piece of information about anything, the best place to search for it is Wikipedia. This online encyclopedia(百科全書) is written by thousands of people around the world. Anyone can add or change the information if he or she finds it not correct or not well written. In this way, people who know a lot about a certain subject can write about it even if they are not university professors.
What is more, Wikipedia includes articles written in about 235 languages. This fact makes it one of the few websites on the Internet that are truly international. It was started in 2001 by Larry Sanger and Jimmy Wales, as a free online English-language encyclopedia project. By April 2008 over 10 million articles had been put on Wikipedia. A quarter of the articles in English. Wikipedia is also a place where people can find the latest news.
However, Wikipedia has its own problems. There have been many complaints that some of the information on Wikipedia is not accurate and some important subjects are not included. This has led to arguments between the writers of articles. The people running Wikipedia say that the accuracy of the information is improving and that it is one of the top 20 visited websites on the Internet.
So, if you are looking for some information, why not try Wikipedia?

Change your light bulbs (燈泡). Use energy-saving light bulbs. And don't forget to turn off the lights when you leave a room and turn off your television and computer when they are not in use!

Say no to plastic bags. The next time your parents go to the market, ask them to use baskets

Everyone tries to get to school on time. But when bad weather gives you trouble, can you still make it before the bell rings?

In northern China during spring, big sandstorms often make trouble for students and everyone else. When the sky is dark with sand, buses and cars all move much more slowly. Sometimes, people can’t even see for 20 metres.

Sandstorms usually happen in spring. This year, sandstorms started in late March. They have happened in more than 10 provinces (省)  in northern China this year. More than 70 million people have had problems in those places because of the sandstorms.

People in southern China don’t have to worry about this kind of bad weather. Most of the sand comes from Gansu and Inner Mongolia（內(nèi)蒙古）. In northern China, lots of places have few trees and don’t get much rain. People there have been cutting down too many trees. When there aren’t many trees, the ground can’t keep enough water. Over the years, the ground dries up and turns to sand. When spring comes and the ice melts（融化）, the ground becomes looser（更松散的）. Strong winds take the loose sand into the sky.

Sandstorms are bad for people’s health. If people breathe（呼吸） too much sand, they could cough or have asthma（哮喘）.

Sandstorms also give farmers lots of problems. Sometimes their sheep get lost in the storms and never get back home. The winds also tear down farmers’ houses.

What can you do to stop sandstorms? Here’s an idea: Ask you parents to help you plant some trees this spring.

If you see people cutting down too many trees, tell them about the dangers of sandstorms, and ask your government to stop them from cutting.
