"Protecting our computers against virus attacks is very important nowadays when computers are commonly and widely used in our home and offices." said a spokesman for the Information Technology Services Department (ITSD).

"Typical payload of computer virus can range from cresting annoyances such as affecting the mouse, keyboard or other computer functions, to more destuctive actions like modifying or deleting files, or exposing secret information from the hard disk of the victim's computer." Some computer virus may format the hard disk to corrupt all data stored inside the computer.

"Besides, there are also computer viruses that will create mass mailing or scanning traffic not only to turn infected computers into a platform. for launching further attacks to other computers, but also to consume mailbox storage and network bandwidth."

"As a result, the network and computer systems will be overloaded and the normal operation of the network and computer systems will be seriously affected." said the spokesman.

He noted that the impact was particularly singnificant due to the current highly interconnected computer notwork environment." To avoid such inconveniences and losses, we should take effective computing practices to prevent our computers from virus infections .In fact, such practices are simple and easy." said the spokesman.

听力原文：Cyber attacks are on the increase against home computer users largely because the

y have lower levels of security protection. That's according to Symantec Corporation that sells computer anti-virus software. Symantec's latest Internet Security Threat Report finds home users account for 86% of all targeted attacks followed by businesses that sell financial services. In addition, attackers are using a variety of techniques to escape detection and prolong their presence on your system. Symantec says there's one reason scammers are going after home computers. "And that's partially because of the data that contain credit card information, social security numbers, and partially because of the machines that control the high speed links which in turn can be used for spamming, and fraud". Symantec says attackers are using a variety of means to steal information and they get more sophisticated every day. "So we've already seen the attackers go from e-mail only to Web browsers. And now we are starting to see them using other techniques, such as instant messaging and phone calls." The company urges computer users to develop Internet streetsmarts and be skeptical of anyone online who asks them to divulge confidential information.

What is this passage about？

A．The development of computer technonogy.

听力原文：A supermarket club card is a new way for people to save money on items they buy.

听力原文： A supermarket club card is a new way for people to save money on items they buy. People used to cut out coupons to save money. Now they use a card that looks like a credit card when they pay for items. Only people with cards can get the lower price.

To get a card, people must give out their name, address, and other personal information. Everything club card users buy is stored on a computer in a file with their name on it. In the coupon days, no one kept track of the things people bought. Now, computers allow huge amounts of information to be saved.

In order to save money with the cards, people could lose privacy. So far, the information, or data, is private. But that could change. There are many companies who might be interested in knowing what people buy. For instance, an insurance company might want to know if their clients buy healthy food, or if people buy a lot of medicine from the store.

People want to make sure there are laws to protect data kept on computers. Stores that use club cards have promised to keep the information private. Some people are afraid the stores might change their minds if companies offered enough money. Some people say the information is worth as much as treasure.

Credit card companies can't tell others where you shop. Telephone companies can't sell a list of numbers you call. But all of this information is on a computer and could be given out. Some people think the store's promise is good enough. Others aren't so sure.

(33)

A．Grocery stores.

B．Video stores.

C．Airlines.

D．All of the above.

听力原文：The competition among producers of personal computers is essentially a race to ge

听力原文： The competition among producers of personal computers is essentially a race to get the best, most innovative products to the marketplace. Marketers in this environment frequently have to make a judgment as to their competitors' role when making marketing strategy decisions. If major competitors are changing their products, then a marketer may want to follow suit to remain competitive. Apple Computer, Inc. has introduced two new, faster personal computers, the Mackintosh II and Mackintosh SE, in anticipation of the introduction of a new PC by IBM, one of Apple's major competitors.

Apple's new computers are much faster and more powerful than its earlier models. The improved Mackintosh is able to run programs that previously were impossible to run on an Apple PC, including IBM compatible(兼容的) programs. This compatibility feature illustrates computer manufacturers' new attitude of giving customers the features they want. Making Apple computers capable of running IBM software is Apple's effort at making the Mackintosh compatible with IBM computers and thus more popular in the office, where Apple hopes to increase sales. Users of the new Apple can also add accessories(附件) to make their machines specialize in specific uses, such as engineering and writing.

The new computers represent a big improvement over past models, but they also cost much more. Company officials do not think the higher price will slow down buyers who want to step up to a more powerful computer. Apple wants to stay in the high price end of the personal computer market to finance research for even faster, more sophisticated computers.

Even though Apple and IBM are major competitors, both companies realize that their competitor's computers have certain features that their own models do not. The Apple line has always been popular for its sophisticated color graphics(图形), whereas the IBM machines have always been favored in offices. In the future, there will probably be more compatibility between the two companies' products, which no doubt will require that both Apple and IBM change marketing strategies.

(33)

A．Because IBM is changing its computer models continuously.

B．Because it wants to make its machines specialize in specific uses.

C．Because it wants to stay ahead of IBM in the competitive computer market.

D．Because it expects its major competitor IBM to follow its example.

听力原文：People in most countries depend on communications technology more than ever befor

听力原文： People in most countries depend on communications technology more than ever before. One day in May, an accident forced millions of Americans to be silent. They had to live and work without the technology they depend on every day.

A telecommunication satellite experienced computer failure. The satellite, known as Galaxy Four, moved from its correct orbit and was unable to receive signals from Earth. A backup computer failed to turn on, and the satellite began to spin out of control.

Galaxy Four was launched in 1993. It cost two hundred fifty million dollars. Galaxy Four provided the major link for millions of pagers, credit card operations, company communications systems, and home satellite equipment. The satellite also was used to send television and radio broadcasts.

The telecommunication satellite failure created big problems for many companies. At least eight of the nation's ten biggest paging companies depend on Galaxy Four. A pager is an electronic device that receives telephone messages. The pager makes a beeping sound when it receives one. Ninety percent of the nation's forty-five million pagers lost service when Galaxy Four failed. Paging companies were unable to provide services to police department, doctors and other individuals.

The satellite failure affected many television and radio broadcasts. Thousands of computer users were unable to use the Internet.

A nearby satellite called Galaxy Six has replaced the Galaxy Four satellite. Signals for broadcasting companies are being sent through Galaxy Six. Another satellite, Galaxy Three-R, is replacing Galaxy Four for paging and other signals. Technical experts had to move each person's satellite equipment to point to Galaxy Three-R. Each move takes about thirty minutes. Technicians say the moves must be exact to within less than a centimeter. They were able to restore service to most customers within a few days.

(23)

A．Millions of Americans began to doubt the efficiency of telecommunications.

B．Millions of Americans sued(起诉)the telecommunications company.

C．Millions of Americans were frightened by the accident and became silent.

D．Millions of Americans bad to live and work without the technology they depend on every day.
