（单词翻译）

Using GPS When Driving

Justin: Okay, we’re ready. Let’s get on the road. 

Fay: Wait! We don’t know where we’re going. We’re strangers in a strange land. Where’s our guide? 

Justin: We don’t need a guide. See this? It’s GPS and it’ll help us navigate¹ to where we want to go. 

Fay: I’m not sure it’s reliable. We’re in a pretty remote location. 

Justin: Relax and let me explain how this works: GPS systems use satellites to locate your current location. Information is transmitted to this receiver, so it always knows exactly where we are. We input² the address of our destination and presto³! It gives us onscreen or voice directions. 

Fay: I know how a GPS system works. I’m worried that there aren’t reliable maps to where we want to go. I read that many printed maps of this region are outdated⁴ and unreliable. 

Justin: Don’t worry. This GPS is the state-of-the-art. I’m sure it’ll be accurate. 

Fay: A fool with a tool is still a fool. 

Justin: What did you say? 

Fay: Nothing.
