Task 3 Read the passage. Fill in the blanks with no more than three words. Do you like traveling? Do you prefer package tours, road trips, or self-planned trips? Of course, with the help of in-car GPS navigation (车载导航), it would be an enjoyable experience to take a road trip or self-planned trip. Twenty years ago, a road trip meant using a bunch of fold-out maps. They were usually stuffed into a bag or a car-door panel pockets. When unfolded, a map was like a giant newspaper. Along the way, those maps gave way to MapQuest or Yahoo Maps print-outs. Obviously, when reading such maps, a strong sense of direction was a must. Fortunately, now we've got navigation devices that we can carry anywhere such as in-dash GPS systems and GPS-enabled smartphones. It's hard to believe that in-car GPS navigation has already been around for more than three decades. But do you know which car company introduced the first navigation system? It was Honda, a Japanese car company. The navigation system was not just a shock to the autoindustry ; it sent the electrical equipment makers running.
