课时作业1Unit 1Section Reading and Thinking.阅读理解 ANo one can believe that the Great Wall might disappear some day. Believe it or not, the Great Wall is being destroyed by people. Less than 20 percent of the Great Wall built in the Ming Dynasty is still perfect, but about 80 percent is in danger. The Great Wall can be called “great” mostly because of its amazing length. But we should realize that the length was made up of one brick at a time. If we do nothing to save the Great Wall, it will become a series of separate wasteland rather than a historic site.The Great Wall is actually a series of walls built and rebuilt by different dynasties over the past 2,000 years. It began in the rule of Chinas first emperor, Qin Shihuang of the Qin Dynasty, and lasted into the Ming Dynasty. The parts built before the Ming Dynasty have nearly disappeared. People are familiar with sections such as Badaling in Beijing and Jiayuguan in Gansu because they have been open to tourists for many years. But_those_sections_far_away_from_the_public_eyes have been almost forgotten.Few local people knew the 3metrehigh walls made of earth and stones beside them are part of the Great Wall. The lack of knowledge is considered as one of the main reasons.The bricks on the Great Wall were carried off by local countryside people to build their houses, sheep corrals (畜栏) and pigsties (猪圈). Some were taken away to build roads. Bricks carved with peoples names are put away as remembrance (纪念). Rubbish is spread over the battlements (城垛). The bricks can be sold for 15 yuan per tractor load. Those who destroyed and are destroying the Great Wall know its name, but are not clear about its cultural meaning. It will take a long time to let them know this. The local farmers not only carried off the body of the Great Wall but dug out the entire base.It is necessary to preserve the Great Wall. The officials should be aware of the importance of the Great Wall. Young Chinese should know more about the nations great civilization and learn to love it.【语篇解读】历史文化古迹长城正在遭到破坏，作者呼吁人们要保护好长城。1The underlined part in Paragraph 2 refers to the parts of the Great Wall _.Athat are too difficult to understandBthat nobody can watchCthat are not well known to the publicDthat are too far to be seen答案与解析：C词义猜测题。根据上文“People are familiar with sections such as Badaling in Beijing and Jiayuguan in Gansu because they have been open to tourists for many years.”和画线部分的But可知，长城有些地方是向公众开放的景点，这当然为公众所熟悉；而那些不是景点的地方则不会为公众所熟悉。2Whats the main reason for the Great Walls being destroyed?
