Question

 No one can believe that the over 6,300 kilometer 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 China's first emperor, Qin Shihuang of the Qin Dynasty (221 BC―206 BC) ,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 Pass 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 3-meter-high 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 behind man-made destroy. The bricks on the Great Wall are carried off by countryside people to build their houses, sheep corrals and pigsties. Some were taken away to build roads. Bricks carved with people's names are put away as remembrances. Rubbish is spread over the battlements. The bricks can be sold for 15 yuan per tractor-load. Those who destroyed and are destroying the 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 Wall but also dug out the entire base.

  It is necessary to protect the Great Wall. First of all,the officials should be aware of the importance of the Great Wall. Young Chinese should know more about the nation's great civilization and learn to love it.

Answer 1

1-4 CCDA 

A篇介绍了长城的相关情况，强调了保护长城的必要性。

1. C细节理解题根据第一段第三句可知，并非长城的所有部分都处在危险当中，有差不多20%是完好的，所以A项错误。根据第三段可知,人们扔的垃圾只是导致长城危险现状的一个方面,B项不全面。根据全文可知，长城虽然古老，但是对于中国的意义不仅仅是古代的防御工事和现代的旅游景点，更是人类伟大文明的象征，是非常有意义的，所以D项错误。

2. C细节理解题从第一段和第二段可知，长城从秦始皇时期始建，延续到明朝，所以A项错误。从全文可知，长城没有得到很好的保护，所以D项有误。B项未提及。

3.D逻辑推理题从第二段最后两句可知，人们熟知八达岭到嘉峪关之间的长城是因为这段长城向人们开放多年了，而远离公众视线的那些区域则几乎被人遗忘，从前面的"be open to"和"but"可知选D。

4. A主旨大意题总结倒数第二段大意可知，因为人们不了解长城的文化重要性，所以长城正在被破坏。
