(统称)一代人 New words hundreds of blow away 数以百计 吹走 New phrases 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 C. Reading Saihanba: turning desert into forest Three generations 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. a Actions and challenges b Efforts and achievements c History and problems Paragraph 1 Paragraph 2 Paragraph 3 1 Choose the best topics for the paragraphs on page 62.
