We shouldn't litter, we need to sort our rubbish. We shouldn’t put waste into rivers and seas. What can we do to protect the Earth? We should plant more trees and turn deserts into green land. What can we do to protect the Earth? We should choose to travel in a low-carbon way. We should save energy and use clean energy, such as wind energy, solar energy. Saihanba, from a tree to a million mu of forest, from desert to oasis, is a miracle created by the Chinese people. Since 1961, after half a century of hard work, Saihanba has been built into a famous man-made forest area, attracting many tourists to come for sightseeing, and has become an important window to show China's ecological civilization.

Think Many people have worked hard to protect our beautiful planet. What challenges do they face? What achievements have they made? 1 Read the article about Saihanba and find out how the desert became a forest. 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°C. 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. Notes In 2007, the government listed Saihanba as one of the most important national nature reserves in China. In 2017, the Saihanba Afforestation Community received the Champions of the Earth award from the UN Environment Programme. 2007年，政府将塞罕坝列为中国最重要的国家级自然保护区之一。 2017年，塞罕坝林场获得联合国环境规划署颁发的“地球卫士奖”。 Notes turn... into... =change ... into ... in the north of... hundreds of... in the 1800s a group of... in the middle of...=in the centre of... cut down thanks to 1.把....变成..... 2.在....的北部 3.数以百计的…… 4.在 19 世 纪 5.一队； 一群…… 6.在……中间 7.砍到 8.幸亏，由于 阅读，在文章中画出这些短语： Language points in 表示在地点内部   on 表示两地接壤   to 表示两地相隔   1.in the north (south / east / west) of ... 在……的北部(南部 / 东部 / 西部)辨析： in the + 方位名词 + of ...， 指在某一范围内的地区； to the + 方位名词 + of ...， 指互不接壤的两个地区； on the + 方位名词 + of ...， 指接壤的两个地区。： 2.When the forest disappeared, there were terrible sandstorms in the Beijing area.当森林消失时，北京地区发生了可怕的沙尘暴 disappear v. 消失；消散 The rocket disappeared into the sky. 火箭消失在空中。 【同根词】 appear v. 出现 She appears on TV at seven every evening. 她每晚7点在电视上露面。 【拓展】 appear, seem与look(似乎;好像) 三者均为连系动词,意为 “似乎;好像;显得。其后均可接形容词名词不定作表语。如: He looks/seems/appears honest.他似乎很诚实。 He looks/seems/appears to be honest.他似乎很诚实。 look, seem之后可以接介词like,但 appear之后不能。 如: He looks/seems like fool.他看起来像个大傻瓜 3.In the early 1960s, a group of scientists travelled to Saihanba to find a solution. 20世纪60年代初，一群科学家前往塞罕坝寻找解决方案。 In the early 1960s 20世纪60年代初 solution：n. 解决办法；处理手段 I do not have a simple solution to the problem. 我没有解决这个问题的简单方法。 Has anyone found a solution to question 7? 谁找到了问题7的解决方法？ 注意：与answer、key、clue（线索）类似的是，solution常跟介词to连用，表“……的”。 4.There are hundreds of millions of trees there. hundreds of 数百的，数以百计的 Those mountains are hundreds of metres high.那些山有数百米高。 【重点】hundreds of 后接复数名词形式。 They plant hundreds of trees every year. 他们每年种几百棵树。 【难点】当hundred前有具体的数词修饰，即表示确切的数目时，hundred只能用单数形式，且不与of连用。另外，hundred前也可用some, several, many等表示不确定的数目的词修饰。 Two hundred students attended the contest. 两百名学生参加了此次比赛。 【拓展】与hundred用法类似的还有thousand, million等。 thousands of数千的　three thousand 三千 (1) How did Saihanba become a desert?

They are the lungs of the Earth, producing oxygen and taking in carbon dioxide, making our air clean. They also provide homes for animals and plants. Forests play a role in the water cycle as they help absorb and filter water, which is important for our survival. In addition, they also provide wood , it is also important to our economy. First we can start by raising awareness about their importance. Second We can help protect forests by not cutting down trees, recycling, and using less paper and wood. Saihanba Saihanba National Forest Park, the largest forest park in northern China, is located in Weichang Manchu and Mongolian Autonomous County in Hebei Province. The word "Saihan" is Mongolian, meaning “beautiful”,. "Saihanba” means ''beautiful highland”. Covering 94,000 hectares, the Saihanba Forest Park is man-made. With over 70,000 hectares of trees, its forest coverage is 80% .It also contains 15,000 hectares of grassland and a vast area of wetland. The forest provides a home for more than 600 plant and nearly 1,000 animal species. The early winter snow turns the air cold in Saihanba. The streams in the valley are yet to freeze over and so the red deer are drawn out of the woods. The reappearance of red deer in the area is a relatively recent phenomenon. In the past, people cut down trees, and they also damaged the environment in other ways. The red deer lost their natural habitat and disappeared. Continue to explore Through decades of hard work by several generations of tree planters, a forest belt over 50 km long from east to west and 17 km wide from north to south was created on the beautiful highland. Thanks to the newly planted forest, animals such as the red deer have finally returned to Saihanba. The forest now protects the plain from sand and dust storms, and also stops the flow of cold, dry air from the north. (1) What does the Mongolian word "Saihanba” mean? Read and think It means beautiful highland. 4.Why have animals, such as the red deer, returned to Saihanba? These animals have returned to Saihanba because it has become a forest again. 5. What positive effect has the newly planted forest had on the area? 2.What is the forest coverage of Saihanba National Forest Park? 3.Why did the red deer disappear from the area in the past? The newly planted forest has helped protect the plain from sand and dust storms and stopped the flow of cold, dry air from the north, leading to the return of animals such as the red deer to Saihanba. The red deer disappeared because people cut down trees and damaged the environment in other ways, causing the loss of their natural habitat. The forest coverage of Saihanba National Forest Park is 80%. Cross-curricular connection I Education Air surrounds the Earth. All living things on Earth need air to survive. What is air like?
