1、This is the VOA Special English Technology Report.这里是 美国之音慢速英语科技报道。Global Positioning Systems are now a part of everyday driving in many countries.

They actually put their home addre ss in. So again, the GPS is kind of garbage in garbage out.布朗：“ 他们输入一个地址然后开往目的
6、地。直到开了三十分钟他们才意识到，他 们实 际上输入了一个回到他们居住的西海岸 的目的地，他们实际上输入了自己的家庭地址。所以说，GPS 有点胡乱输入胡乱输出 。 ”来源:学科网Mister Brown says this is a common human error. But, he says, what makes the pr oblem worse has to do with some of the shortcomings, or failures, of GPS equipment.布朗先生说，这是一次常见的人为失误。但他表示，GPS 设备的一些缺点使得问题更为糟糕。BARRY
7、 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 its going to the wrong place.布朗：“很多 GPS

12、ists several areas where GPS systems can cause confusion for drivers. These include maps that are outdated, incorrect or di fficult to understand. They also include timing issues related to when GPS commands are given.GPS 驾驶的日常问题一书列出了 GPS 可能会导致驾驶混乱的几个方面。其中包括地图过时、错误或难以理解。还包括给出 GPS 命令时的时序问题。Barry Brown says to make GPS systems better we need a better un derstanding of how drivers, passengers and GPS systems work together.布朗表示，为了让 GP S 系统更好用，我们需要更好地了解司机、乘客和 GPS 系统是如何协同工作的。
