It covered many places in thick clouds of yellow dust, including Qinghai, Heilongjiang and Beijing. The dust even traveled to Shanghai and Jiangsu. Where did such a strong sandstorm come from and why? It came from the Gobi Desert areas of Mongolia. This year’s wind was very strong there. It is because the temperatures this spring are higher than before. There was also little rain. So the land was dry and it was difficult for plants to hold sand and dust. China has been working for many years to fight against sandstorms. In the 1970s, China started the Three-North Shelterbelt Forest Program. It planned to plant trees in northern China to stop sandstorms and improve the environment. More than 66 billion trees have been planted so far. But it also needs the effort (努力) of many countries and international cooperation. For example, about 70 percent of the land in Mongolia is facing desertification (沙漠化). Sand in the country has become a source (来源) of sandstorms in China and other countries nearby. How to protect yourself in sandstorms: ☆Stay in a room with the doors and windows closed. ☆If you’re outside, avoid riding a bike. Cover your face and wear special glasses. ☆Stay away from trees if you are outside. ☆Go to the hospital if you are coughing a lot. ☆Airports, highways, and ports should be closed. 9. Where was the big sandstorm in April from? A. Qinghai, Heilongjiang and Beijing. B. The Gobi Desert areas of Mongolia. C. Shanghai and Jiangsu. D. The northern China. 10. Why did China set up the Three North Shelterbelt Forest Program? A. To save the endangered animals. B. To help to grow certain plants. C. To get more wood products. D. To protect the environment. 11. If you are walking outside, how can you protect yourself properly when a sandstorm comes? A. By hiding behind a tree. B. By riding a bike home. C. By covering the face. D. By wearing a hat. 12. What is the main idea of the passage? A. How to stop sandstorms and protect yourself. B. What makes sandstorms happen in the world. C. Where the strong sandstorm in April came from. D. Why China has planted so many trees these years. Ⅳ． 阅读短文，从方框内所列选项中，选出最佳选项填入对应空白处，使短文通顺、连贯。（选项中有一项多余） China used to be poor in technology, but great changes have taken place in recent years.
