It very often happens in the desert. A sandstorm is like a snowstorm. They can happen in towns or villages alike. Sandstorms and snowstorms both cause a lot of trouble for people. In sandstorms, the wind carries the sand. Unlike other disasters, sandstorms come with a warning. If you see that the clouds have a dark, brownish color, it means there is going to be a sandstorm.If there is no rain for a long time, sandstorms may happen. When there are sandstorms in cities, there will be no planes in the sky. It would be dangerous for the pilot to fly the plane because he cannot see clearly. There would also be more traffic accidents in the street. The sky is gray and people cannot see very far.There are many deserts in Africa and Asia. Sandstorms are more likely to happen in these places than in Europe. People can stop sandstorms by planting trees.1. Where do sandstorms often happen?A. In the desert. B. In towns or villages.C.

The visibility was less than 100 meters in Mingin (a place) because of sand. When visibility drops to less than 1 kilometer, is called a sandstorm. The sandstorm in Mingin blew up dust in neighboring towns, such as Beijing, Wuwei, Jinchang and Lanzhou of Gansu Province. Dust-laden winds also swept into Beijing.Brought by northwest wind, blowing at more than 20 meters per second, dust first reached the capitals suburbs at 7 a.m. downtown areas at 9a.m. The ich died down during the night, brought the temperature down to 8 below zero and many flights put off their planned time from the citys airport.Its quite rare for sandstorms, which are frequent between Match and June, to happen in winter, when the earth is frozen. The sandstorms in Gansu and Inner Mongolia do not necessarily mean there will be most of them in the spring than last year, when they were serious but Beijing is taking it very seriously. It is reported that Beijing will spend 6 billion Yuan（U.S.$725million）in preventing sandstorms in the capital and has already set up a special team to make sure what causes them.4.

Why did sandstorms happen in winter?_A. Because there was little snow this season.B. Because a lot of trees have been cut down.C. Because people took few measures to control them.D. Its not mentioned in the passage.THE GREAT GREEN WALLForests help to keep water from running away, so drought does not often happen.The trees in the forests can keep rain drops from hitting the soil directly, so the soil is not easily washed away. The dead leaves on the ground also keep the water from running away. The water then stays in one place and is used by the trees in the forests. In this way, floods are prevented.Chinese people do not want to see more floods and droughts, so they have built a new Great Wall across the northern part of the country. This time, it is a “Great Wall” of trees, millions of trees.The Great Green Wall is 7,000 kilometres long, and between 400 and 1,7
