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, 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'.”
Mister 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 formerly served as a professor with the University of California, San Diego. While there, he 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 These include maps that are outdated, incorrect or difficult to understand.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.

65. What is Mr. Brown’s attitude towards GPS?
A. Unconcerned B. Prejudiced C. Objective D. Critical
66. What would be the best title for the text?
A. driving with GPS can be difficult

名校课堂系列答案An increase in students applying to study economics (经济学) at university is being attributed to （归因于）the global economic crisis (危机) awakening a public thirst for knowledge about how the financial system works.
Applications for degree courses beginning this autumn were up by 15% this January, according to UCAS, the Universities and Colleges Admissions Service. A spokesman for the Royal Economic Society said applications to do economics at A-level were also up.
Professor John Beath, the president of the society and a leading lecture at St Andrews University, said his first-year lectures which are open to students from all departments—were drawing crowds of 400, rather than the usual 250.
“There are a large number of students who are not economics majors, who would like to learn something about it. One of the things I have done this year is to relate my teaching to contemporary events in a way that one hasn’t traditionally done. ” He added.
University applications rose 70% last year. But there were rises above average in several subjects. Nursing saw a 15% jump, with people’s renewed interest in careers in the pubic sector（部门）, which are seen as more secure in economic crisis.
A recent study showed almost two thirds of parents believed schools should do more to teach pupils about financial matters, and almost half said their children had asked them what was going on, although a minority of parents felt they did not understand it themselves well enough to explain.
Zack Hocking, the head of Child Trust Funds, said: “It’s possible that one good thing to arise from the downturn will be a generation that’s financially wiser and better equipped (使…有能力) to manage their money through times of economic uncertainty.”
