课时跟踪检测（一） Introduction & Reading Pre-reading阅读理解ATwo billion children in the developing world cant receive good education the key to human development. However, technology offers an answer which allows the poor in developing countries to learn. It is a tool which holds the ability to change the lives of the poor, as it provides a means of learning and communicating.Educational programs must break away from old systems. New companies such as One Laptop(笔记本电脑) Per Child (OLPC), an organization founded by MIT Professor Nicholas Negroponte have been active in solving the worlds education problem.The Internet has changed the world, allowing educational services to help with the global fight against poverty. Khan Academy is one such service. Like OLPC, it is an organization founded by Harvard Business School graduate Salman Khan with the task of “providing a world-class education to anyone, anywhere.” The education offered includes a large number of math-related topics.The GMAT Pill Review is another company that trains MBA candidates(应考人) worldwide to prepare for the GMAT exam on both the Quant and Verbal section. Founded by Stanford graduate Zeke Lee，the company offers services which are priced at about 75% less than other similar programs. It allows students from developing countries who might not be able to afford similar courses to have access to these services.Whether paid or free these services provide educational opportunities to those who would never have had the chance in the past. As a result of the technology revolution(革新), business schools may see more students from different corners of the world. Because of the Internet, people in developing nations have access to better and more affordable educational opportunities. More and more people will try to improve their lives through educational opportunities outside of their homeland an idea usually uncommon in developing countries.语篇解读：本文主要介绍了发达国家通过科技手段帮助发展中国家的人们接受教育的几个组织。1According to the text, technology can .Aimprove peoples reading abilityBsolve the problems facing the whole worldChelp the poor to reduce povertyDcause poverty in developing countries解析：选C细节理解题。根据第一段第三句“It is a tool which holds the ability to change the lives of the poor, as it provides a means of learning and communicating.”可知，由于科技提供学习和交流的方法，所以它是能够改变穷人命运的工具。2We can learn from the text that Khan Academy aims to .Ahelp the poor pay for good coursesBprovide every child with a computerChelp train MBA candidatesDmake everyone receive good education解析：选D细节理解题。根据第三段第三句“Like OLPC . with the task of providing a world-class education to anyone, anywhere.”可知，该组织的目的是使每一个人都得到世界一流的教育。3Which of the following about GMAT Pill Review is TRUE?AIt only accepts students from developing countries.BIt was started by Professor Nicholas Negroponte.CIt charges students about 25 percent of other similar programs.DThe education it offers includes a lot of math-related topics.解析：选C细节理解题。根据第四段第一句可知，GMAT Pill Review在全世界范围内招生，A项错误；由第四段第二句可知，它由Zeke Lee创办，学费比其他同样的学校便宜75%，因此B项错误，C项正确；D选项是叙述Khan Academy的，因此错误。4In the past，people in developing countries .Ahad no educational opportunities in their homelandBseldom thought of receiving foreign education to change themselvesCalways believed education was of great importanceDwouldnt leave their homeland to reduce poverty解析：选B推理判断题。由文章最后一句可知，现在越来越多的人通过本国之外的教育机会来改善他们的生活，这一点在过去的发展中国家是不常见的。由此可以推断出，过去发展中国家的人们很少想到通过接受国外的教育来改变自己的命运。BUsing too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving (铺砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater. Human activity is not responsible for all water shortages (短缺). Drier climates are of course more likely to have droughts (干旱) than areas with more rainfall，but in any case, good management can help to make sure there is enough water to meet our basic needs. Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day！This shows how much we depend on water to live, but theres a lot we can do to lower the number. You can take steps to save water in your home. To start with，use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗机) only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.语篇解读：本文为一篇议论文。文章讨论的是人类活动对于水供应的隐形影响。5Which of the following is most likely to lead to less
