6.Global Positioning Systems are now a part of everyday driving in many countries.These satellite-based systems provide turn-by-turn directions to help people get to where they want to go.But,they can also cause a lot of problems,send you to the wrong place or leave you completely lost.Many times,the driver is to blame.Sometimes a GPS error is responsible.Most often,says Barry Brown,an expert in human-computer interaction,it is a combination of the two.We spoke to Mr.Brown by Skype.He told us about an incident involving a friend who had flown to an airport in the eastern United States.There he borrowed a GPS-equipped car to use during his stay.Barry Brown:"And they just plugged in an address and then set off to their destination.And,then it wasn't until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived.They actually put their home address in.So again,the GPS is kind of'garbage in garbage out'".
Mr.Brown says this is a common human error.But,he says,what makes the problem worse has to do with some of the shortcomings,or failures,of GPS equipment.Barry Brown:"One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn.Because they just give you the next turn,sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place."
Barry Brown once worked on a project with Eric Laurier from the University of Edinburgh.The two men studied the effects of GPS devices on driving by placing cameras in people's cars.They wrote a paper based on their research.It is called"The Normal,Natural Troubles of Driving with GPS".It lists several areas where GPS systems can cause confusion for drivers.These include maps that are outdated,incorrect or difficult to understand.They also include timing issues related to when GPS commands are given.
Barry Brown says to make GPS systems better we need a better understanding of how drivers,passengers and GPS systems work together.
28.In Paragraph 2,Mr.Brown mentioned his friend in the conversation toD.

B.It gives the driver the overview.
C.Its screen is too small to be seen clearly.
D.It is only suitable for passive drivers.
30.Which of the following statements would Barry Brown most likely agree with?D
A.GPS units are to blame for most GPS service failures.
B.We should introduce higher standards for the driving license.
C.Cameras are urgently needed to help improve GPS systems.
D.Drivers,GPS systems and passengers should unite to improve GPS systems.
31.What is Mr.Brown's attitude towards GPS?B
A.Unconcerned.
B.Objective.
C.Negative.
D.Critical.
分析 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,需要司机、乘客和全球定位系统的协调工作.
解答 28.D 写作意图题.根据第二段的They actually put their home address in.和下面的句子:Mister Brownsays this is a common human error.可知Mr Brown是在举人的错误的例子.故选D.
29.A 细节理解题.根据文章第三段的One problem with a lot of the GPS units is that theyhave a very small screen and they just tell you the next turn.可知,GPS的一个问题是屏幕很小,并且它仅仅告诉你下一个转弯.所以它只能一次告诉司机转一次.故A正确.
30.D 细节理解题.根据最后一段的Barry Brown says to make GPS systems better we needa better understanding of how drivers,passengers and GPS systems worktogether.可知Barry Brown认为GPS系统,司机和乘客应该一起努力提高.故D正确.
31.B 推理判断题.作者在文章中只是客观的评价GPS的优缺点,故作者的态度是客观的.故B正确.
点评 本文是科教类阅读,主要考查细节理解题和推理判断题.在做细节理解题时,首先根据题目要求迅速在文章里找出相应的段落、句子或短语.认真比较选项和文中细节的区别,在做推理判断题时不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
