题目

Many years ago, people relied on the sun, the moon and stars to find their way around. Later, the compass was introduced. And now, we have satnav（卫星导航）systems to guide us. A satnav system uses groups of satellites to show the user’s location. They send information to a receiver, such as a smartphone, to show us where we are.The earliest built satnav system is the Global Positioning Satellite System, which belongs to the US. Then there is Russia’s Global Navigation Satellite system，the European Union’s Galileo and China’s own satellite navigation system, Beidou.On October 18, 2017, an ARJ21-700 plane, which was the first domestically（国内地） produced jet equipped with the Beidou navigation system, successfully completed a test flight. The results showed the performance of the system developed by China matches that of similar systems produced abroad, according to the Commercial Aircraft Corporation of China.Since its introduction in 2000, the Beidou navigation system has been increasing numbers of applications linked to everyday life, from shared bikes to farming.When it comes to shared bikes, smart locks that support Beidou chips offer more accurate positioning than others, making it easier to find a bike.Farmers can use Beidou-enabled tractors to plow（犁）the soil and use unmanned aircraft with Beidou to sow seeds, which can improve efficiency and make better use of resources. Beidou’s farming applications have spread from Heilongjiang Province to Beijing, Liaoning, Shanxi, Hubei and other regions across China.With its many uses, the Beidou navigation system is even playing a big role in the Belt and Road Initiative（一带一路）. “To date, the Beidou system has covered most parts of the Asia-Pacific region, as well as countries along the Silk Road Economic Belt and the 21st Century Maritime Silk Road,” said Yang Changfeng, chief designer of the Beidou system.Today, there are more than 20 Beidou satellites above our heads, and China plans to launch even more this year to expand the Beidou network to better serve the Belt and Road Initiative.“As Beidou expands its overseas reach, it will be increasingly popular in the logistics（物流） industry,” said Miao Qianjun, Secretary General of the navigation services association. “Ships, for example, can use it to position themselves while sailing across oceans to European countries, no longer limited to Southeast Asian regions in the near future.【1】What is the purpose of the first two paragraphs?A. To compare some modern satnav systems.B. To describe the benefits of satnav systems.C. To tell us how satnav systems were created.D. To introduce some satnav systems and their functions.【2】What can we know about the Beidou navigation system according to the article?A. It was used successfully in a new jet plane.B. It is more powerful than other satnav systems.C. It was introduced to China on October, 2017.D. It wasn’t used in our everyday life until recently.【3】According to the article, the Beidou navigation system is already widely used for _______.A. plowing the soil and sowing seedsB. improving the efficiency of networkC. producing more smart locks for shared bikesD. navigating ships across oceans to European countries【4】What is Miao Qianjun’s attitude toward the future of the Beidou system?A. Worried. B. Casual.C. Positive. D. Doubtful. 答案：【答案】【1】 D 【2】 A 【3】 A 【4】 C 【解析】这是一篇新闻报道。文章介绍了中国的卫星导航系统北斗在生活中的重要作用。【1】推理判断题。答案定位在第一段A satnav system uses groups of satellites to show the user’s location. They send information to a receiver, such as a smartphone, to show us where we are.介绍了卫星导航系统的运用和作用；第二段介绍了世界上几个国家的卫星导航系统，所以前两个自然段的目的是介绍了几种卫星导航系统及其功能，故选D。【2】细节理解题。答案定位在第三段On October 18, 2017, an ARJ21-700 plane, which was the first domestically（国内地） produced jet equipped with the Beidou navigation system, successfully completed a test flight.（2017年10月18日，首架搭载北斗导航系统的国产飞机ARJ21-700成功完成试飞。）故选A。【3】细节理解题。答案定位在第六段Beidou’s farming applications have spread from Heilongjiang Province to Beijing, Liaoning, Shanxi, Hubei and other regions across China. （北斗的农业应用已从黑龙江省扩展到北京、辽宁、山西、湖北等各地，已经被广泛使用），由此可知据文章介绍，北斗导航系统已经广泛应用于耕地和播种，故选A。【4】推理判断题。答案定位在最后一段“As Beidou expands its overseas reach, it will be increasingly popular in the logistics（物流） industry,” said Miao Qianjun（“随着北斗向海外扩张，它在物流业中将越来越受欢迎，”苗千军说。）由此推断出Miao Qianjun对北斗系统的未来持积极态度，故选C。推理判断题要求考生在理解原文表面文字信息的基础上，做出一定的判断和推理，从而得出文章的隐含意义和深层意义。推理判断题属于主观性较强的高层次阅读理解题，做这类题目时，同学们应严格依据作者所陈述的细节、事实以及作者的措词、态度和语气等，找出能够表露作者思想倾向和感情色彩的词语，然后利用自己已获得的相关知识进行推理判断，从而得出符合逻辑的结论。小题4，答案定位在最后一段“As Beidou expands its overseas reach, it will be increasingly popular in the logistics（物流） industry,” said Miao Qianjun（“随着北斗向海外扩张，它在物流业中将越来越受欢迎，”苗千军说。）由此推断出Miao Qianjun对北斗系统的未来持积极态度，故选C。
