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 twenty meters.

Sandstorms usually happen in spring. This year, sandstorms started in late March. They have happened in more than ten provinces (省) in northern China this year. More than seventy 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 (内蒙古). 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 are not many trees, the ground can’t keep enough water. Over the years, the ground dries up and turns to sand. When spring comes, 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) in too much sand, they could cough or have asthma (哮喘).

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

What can you do to stop sandstorms? Here is an idea: Ask your 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.

The Internet is becoming important in our life. How much do you know about it? The following questions and their answers will help you to know more about the Internet.

What is the Internet?

The Internet is a large, world-wide collection (聚集) of computer networks (网络). A network is a small group of computers put together. The Internet is many different kinds of networks from all over the world. These networks are called the Internet. If you have learned to use the Internet, you can have a lot of interest on the World Wide Web (网) .

What is the World Wide Web?

The World Wide Web has been the most popular development of the Internet. It is like a big electronic (电子) book with millions of pages. These pages are called homepages. You can find information about almost anything in the world on these pages. For example, you can use the Internet instead of a library to find information for your homework. You can also find information about your favourite sport or film star, talk to your friends or even do some shopping on the pages. Most pages have words, pictures and even sound or music.

What is e-mail?

Electronic mail (e-mail) is a way of sending messages to other people. It’s much quicker and cheaper than sending a letter. If you want to use e-mail, you must have an e-mail address. This address must have letters and dots (点) and an @ (means “at”). For example: Lily @ Yahoo.com. Write a message, type a person’s e-mail address, and then send the message across the Internet. People don’t need to use stamps, envelopes or go to the post office because of the invention of the Internet. Quick, easy and interesting — that’s the Internet.
