Whether you're heading into the wild or down the road, it's hard to find a better electronic sidekick than a GPS. (Well, you know, other than a cell phone.)

       Because a GPS has to receive a signal from space, physical impediments(遮擋) like skyscrapers, cliff faces, and even trees can stump(阻斷) it. Reception is less of an issue with the ultrasensitive(超靈敏) chipsets in newer models, but if the walls are closing in on you, take a tip from a time when navigation systems weren't the streamlined panels they are today: Hooking up an antenna(天線) will make use of even the most tenuous celestial connection. There's a port on the back of most GPS devices for jacking in.

       You'll also want to remember that a GPS is not a compass: It runs on software. Like your PC, it needs to communicate with the mother ship periodically. Vendors(供應(yīng)商) refresh firmware and maps on a regular basis, sometimes even daily. These updates deliver new bits of data that significantly affect your gadget's accuracy. But if you live in the boonies(郊區(qū)) on a road named after your sister-wife, don't expect NavTeq to come a-knocking with its survey equipment. Fortunately, most companies make it easy to update your own maps. Usually it's as simple as plugging into your home computer, dropping a couple of pins in Google Maps, and clicking Save.

       If you own a new Tom Tom, it's even easier. You can edit maps on the unit itself, though you might not have to: Some of the company's navigation updates themselves. Tom Tom's IQ Routes software takes data from every person who uses the company' gadgets and readjusts its assumptions about which roads you should use and how long a given route will take. It will even change its own maps.

       See, it's not that hard: Your GPS may use NASA technology, but getting the most out of it isn't rocket science.

46. The writer thinks the useful electronic partner is __

____besides a cell phone when driving outdoors.

       A. a GPS             B. Tom Tom's IQ Routes            C. a PC        D. NASA

47. Which statement is NOT true about a GPS according to the passage?

       A. It receives a signal from space.

       B. It is not a compass.

       C. It needs to refresh its information.

       D. It has no port to connect other equipment.

48. You may learn from the passage that Tom Tom (Para 4) is _______.

       A. a GPS receiver

       B. a device that can be used to edit maps

       C. a device that can be used to update software

       D. a person who readjusts GPS assumptions

49. The main idea of the last paragraph is _______.

       A. that we should make the most of GPS in rocket science

       B. that getting the most out of GPS is too difficult

       C. getting the most out of GPS is very easy

       D. GPS owns NASA technology

50. Which is not mentioned about a GPS according to the passage?

       A. Its usage.          B. Its price and shape.   C. Its technology.      D. Its benefit.

Long bus rides are like television shows. They have a beginning, a middle, and an end with commercials (商業(yè)廣告) thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. “Buy Super Clean Toothpaste.” “Drink Good Wet Root Beer.” “Fill up with Pacific Gas. “Only when you have fallen asleep, which is equal to turning the television set off, can you get separated from the unending cry of “You Need It! Buy It Now!”

As for the ride itself, the beginning of it is comfortable and somewhat exciting, even if you’ve traveled that way before. Usually some things are keeping changing out of the windows — various houses, crop fields, attractive bridges, … and sometimes even a small accident. Your bus driver may have a unique style of driving and it’s fun trying experience it the first hour or so. If the driver is particularly reckless (魯莽的) or daring, the ride can be as thrilling (驚心動(dòng)魄的) as an adventurous story. Will the driver pass the truck in time? Will the driver move into the right or the left hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you’ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.

The end of the ride is somewhat like the beginning. You know the riding will soon be over and there’s a kind of expectation and excitement with that. The seat, of course, has become harder for the hours having passed. By now you may sit with your legs crossed, or with your hands in your lap, or with your hands on the arms, or even with your hands crossed behind your head. That is to say that the end comes just at no more ways to sit.

1.According to the passage, what do the passengers usually see when they are on a long bus trip?

A．Buses on the road.                      B．Films on television.

C．Advertisements on the billboards.           D．Gas stations.

2.What is the purpose of this passage?
