Unit 5 Amazing nature 单元话题任务型阅读练习 基础语篇巩固练 Saihanba: turning desert into forest Saihanba is a forest park in the north of Hebei. It is about 400 km from Beijing. For hundreds of years, the emperors went there to hunt. But in the 1800s, things began to change. There were forest fires and wars, and people cut down many trees. Saihanba slowly turned into a desert. When the forest disappeared, there were terrible sandstorms in the Beijing area. In the early 1960s, a group of scientists travelled to Saihanba to find a solution. They found an old tree in the middle of the desert. “Maybe we can still plant trees here,” they thought. In 1962, the first tree planters arrived in Saihanba. The cold and dry weather made their work very difficult, and strong winds blew away many young trees. In winter, it got as cold as -40℃. Three generations (代) of forest workers continued the hard work. Thanks to them, Saihanba is green again. It is today the world’s biggest man-made forest. There are hundreds of millions of trees there. The forest helps provide the capital with clean water, and there are fewer sandstorms in the Beijing area now. 1．Why did Saihanba become into a desert 2．What made it difficult to turn the desert into a forest 3．Are there many sandstorms in the Beijing area now 4．Why are forests important Write 30 words or more. 【答案】1．Because there were forest fires and wars, and people cut down many trees. 2．The cold and dry weather, strong winds. 3．No, there aren’t. 4．Forests are very important because they can provide people with wood, adjust the climate, increase precipitation, absorb carbon dioxide and release oxygen, purify the air, improve our living environment and prevent sandstorms. 【导语】本文主要介绍了塞罕坝林场的发展和建造过程，及其重要作用。 1．根据“There were forest fires and wars, and people cut down many trees.
