Activity 1 Guess the meaning of underlined words 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（皇帝） 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 disappeared①, there were terrible sandstorms in the Beijing area. In the early 1960s, a group of scientists travelled to Saihanba to find a solution②. 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. Three generations of forest workers continued③ 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(首都) with clean water, and there are fewer sandstorms in the Beijing area now.
