危险之旅中的天助_英汉双语

 

for three groups of explorers formed by college students and young white collars, it started out as a wonderful trip. they were enjoying themselves exploring the inner mongolian desert. but when the sandstorm came, the trip became a disaster. 对于由大和年轻白领组成的这三支探险队来说,一开始,他们的旅途非常愉快,他们充分享受着在内蒙古沙漠探险的乐趣。但是,当沙尘暴袭来时,沙漠之旅变成了一场灾难。  the drama unfolded during the may day holiday. one girl did not make it before the students were rescued. the group was eventually found with the help of a gps receiver.   这次戏剧性的事件发生在五一假期期间。其中一名女孩没能等到和们一起获救就永远地离开了。最后,在gps接收器的帮助下找到了他们。  gps, or global positioning system, is a satellite-based navigation system made up of a network of 24 satellites. it was originally created for military use by the us in 1980s but is now available for civilian use. gps works in any weather conditions, anywhere in the world, 24 hours a day. and the service is free.    gps,或者说全球定位系统,是一种基于24颗卫星网络的卫星导航系统。它最初在20世纪80年代由美国研制做军事之用,但现在已可民用。gps可以一天24小时进行全天候、全球性的服务。而且,这种服务是的。  gps satellites circle the earth twice a day and transmit signals and information to the earth. gps receivers take this information and calculate the user's exact location. a gps receiver must be locked on to the signals of at least three satellites to calculate the latitude and longitude of its location. with four or more satellites in view, the receiver can determine the user's altitude. once the user's position has been determined, the gps receiver can calculate other information, such as speed, direction, distance to destination, and a whole lot more.   gps卫星一天环绕地球两次,向地球发送信号和各种信息。gps接收器利用接收到的信息计算出用户的具体位置。一台gps接收器必须追踪至少由三个卫星传送回的信号,才能计算出具体位置的纬度和经度。通过综合比较四个或者更多卫星的传送结果,接收器能够判断出用户所在的海拔高度。一旦定位了用户位置,gps接收器就可以计算出其它信息,比如速度、方向、到达目的地的距离以及更多其它。
