　 　Typing your password or credit card number into a computer is a moment’s work. But if you think your personal details disappear as soon as you hit the Return key, think again: they can sit on the computer’s hard disk for years waiting for a hacker to rip them off.

　　　 As people spend more time on the web and hackers become more sophisticated, the dangers of storing personal information on computers are growing by the day, security experts say. There are some safeguards, such as never allowing your computer to store your passwords. But even that is no guarantee of security.

　　　 When you type in a password, it is stored in random access memory (RAM), where it is held temporarily until other data overwrites it or the computer is switched off.

　　　 But every so often, the computer copies the contents of its RAM onto hard disk, where it is easy prey for a hacker, who can read it directly or design a worm to e-mail it back. The longer sensitive data stays in RAM, the more likely it is to be copied onto the disk, where it stays until it is overwritten-which might not happen for years.

　　　 Tal Garfinkel and colleagues from Stanford University have created a software tool which simulates the workings of a complete computer system. Within the simulation, sensitive data can be tagged and then tracked as it passes through the system. Next, Garfinkel and his team simulated computers running common software that regularly handles passwords or confidential personal information, such as Internet Explorer, the Windows login script and Apache server software.

　　　 In a paper to be presented, they conclude that the programs took virtually no measures to limit the length of time the information is retained. Some of the tested software even copied the sensitive information, apparently without restraint.

　　　 This is the first time anyone has tried to measure the extent of this problem, says Rebecca Wright, a security expert at Stevens Institute of Technology. Garfinkel hopes the results will arouse software developers to take action.

40．Which of the following statements is true according to the passage?

　　　 A．It is secure to use your password as long as you hit the Return key.

　　　 B．Your personal details is likely to be in danger if you spend more time on the web.

　　　 D．Never allowing your computer to store your passwords will be safe.

41．Which of the following is NOT the reason for the unsafety of a password?

　　　 A．It will be stored in RAM.

　　　 B．It will be copied onto hard disk.

　　　 C．It might not be overwritten.

　　　 D．It will disappear as soon as you hit the return key.

42．Tal Garfinkel and his team measured the extent of security of　　　　 .

　　　 A．simulating the working of a complete computer system

43　 What can be inferred from the passage?

　　　 A．The length of the time the information is stored is not limited.

　　　 B．The programs can not retain the information.

Some experts feel that cars are certain to fall into disuse. They see a day in the not-too-distant future when all cars will be deserted and made useless. Other experts, however, think the car is here to stay. They hold that the car will remain a leading means of city travel in the foreseeable future.

The car will undoubtedly change greatly over the next 30 years. It should become smaller, safer, and more practical, and should not be powered by the gas engine. The car of the future should be far more pollution-free than present types.

Unless changes take place in the power system, the car in the future will still be the main problem in city traffic jams. One suggested solution to this essential problem is the automated(自动的)system, which seems to hold water.

When the car enters the highway system, a small arm will drop from the car and connect with a rail, which is similar to those powering subway trains electrically. Once joined to the rail, the car will become electrically powered from the system, and control of the car will pass to a central computer. The computer will then monitor all of the car’s movements.

The driver will use the telephone to dial instructions about his position and the place he heads for into the system. The computer will find the best way and reserve space for the car all the way to the correct exit from the highway. The driver will be free to relax and wait for the call that will warn him of his coming exit .It is believed that an automated highway will be able to deal with 10, 000 cars per hour, compared with the 1,500 to 2,000 cars that can be carried by a present –day highway.

36．What is the main concern of the author of the passage?

　　　 A．How to make cars pollution-free.

　　　 B．How to make cars smaller and safer.

　　　 C．How to solve the problem of traffic jam.

　　　 D．How to develop an automated subway system.

37．We can infer from this passage that 　　　　.

　　　 A．the car connected to the rail on the highway will be powered by electricity

　　　 B．the lack of oil is forcing people to find new means to power automobiles

　　　 C．the driver under the system will be told where to get out of the highway

　　　 D．The future car will become larger, faster, prettier and less expensive

38．What provides cars with electric power in an automated highway system?

　　　 A．An engine.　　　　　　　　　　　　　　 B．A rail.　　　　　

　　　 C．A computer controller.　　　　　 D．A small arm.

39．Which of the following statements is true according to the passage?

　　　 A．The driver puts his information in the system by e-mail.

　　　 B．The new system can deal with 10 times as many cars as the present one.

　 　 C．After entering the automated system, the driver needs to do nothing but relax himself.

　 　 D．Some experts are not confident of the future, while the author is in favor of the opposite
