With the increasing numbers of smart phones and Chinese Internet users, micro blogging, known as Weibo in Chinese, has become more and more popular. Popular websites have created their own Weibo sites, which allow users to post a message of up to 140 words, along with pictures and videos（视频）.
In August 2009 the largest website in China —— “sina.com” firstly set up sina Weibo”, helping micro blogging enter the mainstream in China. In 2010, Internet giants sohu, yahoo, baidu also sent up their own Weibo sites. By the end of October 2010, only sina’s Weibo site had registered（登记）more than 50 million users, with an average of 40 people opening a Weibo site every second. Weibo allows people to post messages quickly using their mobile phones, to stay in touch with friends, and provides channels for different people to communicate.
As the social influence of Weibo continues to grow, more and more news agencies（通讯社）and government departments are beginning to send information through Weibo sites. Wang Peng, a Weibo blogger, said, “Through Weibo it allows me to send my advice to director of my news agencies. Also, I can keep in touch with friends. There are many middle school and university classmates on my blog”. With sending more information to people, the influence of micro blogging in China is increasing.

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（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 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.
