It is a space-based system that provides position and time information in all weather conditions. GPS can help people get to where they want to go.　 　When this happens, the driver is often to blame. Sometimes a GPS error is responsible. Most often, it is a combination of the two. 　 　Barry Brown, a GPS technologist, took an incident as an example. His friend once flew to an airport in the eastern United States. There he borrowed a GPS-equipped car to use. He wrongly plugged in the home address in the west. It wasn't until he was driving for thirty minutes that he realized it. Mr. Brown says this is a common human error. But he says, “One problem is that GPS has a very small screen and it can just tell you the next turn.　 �———� “The Normal and Natural Troubles of Driving with GPS” lists several areas where GPS can cause difficulties. They include maps that are outdated, incorrect or difficult to understand. 　 　GPS may fail due to these reasons and then lead to confusion for the drivers. Although GPS sometimes causes difficulties when people are driving, the most attractive point of this system is its 100% coverage on the planet. It is important for you to have to know what you are doing when you use GPS. You need to have the “ability” to be able to use GPS because it sometimes goes wrong.　 　 A. There are quite a few situations showing the problems of using GPS. B. That means that it is not really telling you about going to the wrong place. C. This space-based system is an important tool for civil and commercial users. D. But sometimes it sends you to the wrong place or leaves you completely lost. E. They also contain timing problems related to when GPS commands are given. F. Advances in technology play an active role in modernizing GPS in many ways. G. To make GPS well used, you need a good understanding of how drivers and GPS work. 【答案】D；A；B；E；G 【知识点】科普环保类；七选五 【解析】【分析】说明文。本文是一篇科技说明文。通过科学调查分析表明：全球定位系统出现的问题是司机和全球定位系统失误两个方面的原因造成的。为了使全球定位系统更好的为我们服务，我们需要更好的理解司机、乘客和全球定位系统的协调工作。 （1）考查对上下文的理解和推理判断能力。前文说GPS的便利，下文说出现的问题，可推，文意反转，与D项BUT吻合。故答案为D。 （2）考查对上下文的理解和推理判断能力。后文举例具体说存在的问题。此句是段落主题。与A项吻合。故答案为A。 （3）考查对上下文的理解和推理判断能力。前文说GPS告诉你下一个拐弯，不等于告诉你去错误的地点，与B项吻合。故答案为B。 （4）考查对上下文的理解和推理判断能力。前文说GPS出现的若干问题，选项E列举了另一个问题，文意连贯。故答案为E。 （5）考查对上下文的理解和推理判断能力。此句在段尾，是对本段的总结。故答案为G。 【点评】科普文客观题的解题方法 1.“找”。读完材料，审完题干(题干不可不审清)，可根据题干确定选项的大致范围，开始 ... ...
