听力原文： Most of the students who come to America pay for their education with their own money or with money from their family. The group NAFSA, an association of international educators, says this is true of 81 percent of students. That is because not much financial aid is offered to foreign students in the United States. Foreign graduate students have more chances than undergraduate students do. Still, 47 percent of foreign graduate students pay for their studies with their own money or their family's money.
Most financial aid from government and private groups is restricted to American citizens. Some countries provide aid for their citizens to study in the United States, on the guarantee they return home to work.
The United States government provides aid for students from some countries. You can ask for details at an American Embassy or an office of the United States Agency for International Development. A local university may also have such information. And some American schools do provide financial aid for foreign students. A list of these can be found at a useful Website. The address is edupass, org. The site also provides information about where to write for financial help. And it warns foreign students net to pay if any money is requested for scholarship application forms. You could be cheated. This site also tells how to order publications such as "Funding for U.S. Study—A Guide for International Students and Professionals". This guide lists more than 600 places where international students can get help paying for their studies. You can also go to the site which is operated by the State Department, which is quite informative.
A lot of information about financial aid can be found on the Internet. If you do not have a computer, you might be able to use one at a local school or an educational advising center to search the information you want.

Computers in Cars
You"re far from home on a lonely mad. Shadowy forests stretch away on both sides. A thick mist（雾） makes it difficult to see far beyond your car"s windshield （挡风玻璃）.
"Can this be route 90A？" you wonder. If it is， you should be near a town. Yet there"s no hint of one. Night is closing in. And you"re low on gasoline.
This is a situation where an in-car computer that can navigate would be a big help.
A car computer that navigates？ Yes! Such computers exist. Several experimental models are being tested by General Motors， Ford， Chrysler， and several foreign car makers. These computers vary in detail. But they all contain series of maps on videodiscs or videotapes. For example， one computer system contains 13，300 maps covering the continental US.
Before starting out on a trip， a driver can type in the code for the region he or she plans to drive through. The computer then shows a map of that region. At the same time， a tiny radio receiver linked to the computer goes to work. It picks up signals from navigation satellites such as the NAVSTAR network. Using these signals， the computer shows the car"s position at all times and displays this position on the map. The computer can also calculate and display the best route to follow.
A navigation computer may also receive and use data about road construction， weather conditions， and traffic jams. This information would be displayed to the driver and the computer would also use the information to work out alternate （交替的）routes。
Most cars nowadays also contain computers that help cars run more efficiently. Microprocessors （微处理机） control certain engine functions by regulating the mixing of fuel. Data on car speed， oil pressure， revolutions per minute， engine temperature， and fuel level can be displayed as digital data （numbers） or warning lights.
Some auto designers suggest that a central computer display be used to clearly present such timely information as car speed and fuel level. Warning lights would indicate a drop in oil pressure or a sudden rise in engine temperature. To get more information on these conditions， the driver could call it up on the computer display screen. When needed， the computer could be"asked" to provide navigation aid or information about the car"s condition.
By describing a typical situation of a lost driver on the road， the author intends to 查看材料
A.make us believe how complex the highway computer network is
B.let us know how in-car computers are linked to road signs
C.show us how helpful a navigation computer can be
D.tell us that NAVSTAR has come into use
