The computer lovers talk about how useful computers can rein business, in education and in the home--apart from all the games, you can do your accounts on them, use them to control your control heating, and in some places even do your shopping with them. Computers, they say, will also bring some leisure, as more and more unpleasant jobs are taken over by computerized robots.
The haters, on the other hand, argue that computers bring not leisure but unemployment. They worry, too, that people who spend all their time talking to computers will forget how to talk to each other. And anyway, they ask, what's wrong with going shopping and learning languages in classroom with real teachers？ But their biggest fear is that computers may eventually take over human, beings altogether.

听力原文： For good or bad, computers are now part of our daily lives. With the price of a small home computer now being lower, experts predict that before long all schools and businesses and most families in the rich parts of the world will own a computer of some kind. Among the general public, computers amuse strong feelings--people either love them or hate them.

West lake College in Virginia will start a laptop computer program that allows students to do school work anywhere they want. Within five years,each of the 1,500 students at the college will receive a laptop. The laptops are a part of a $10 million computer program at West lake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to “speak”with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all!
Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students.
State Officials also are testing laptop programs at other universities,too.
At West lake College, more than 60 percent of the staff use the computers. The laptops will allow all teachers to use computers in their lessons. As one West lake teacher said, “Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.”

Janice Weinman of the American Association of University Woman says, "Girls tend to be less comfortable than boys with the computer. They use it more for word processing rather than for problem solving, rather than to discover new ways in which to understand information."
After re-examining a thousand studies, the American Association of University women researchers found that girls make up only a small percentage of students in computer science classes. Girls consistently rate themselves significantly lower than boys in their ability and confidence in using computers. And they use computers less often than boys outside the classroom.
The instructor of this computer lab says he's, already noticed some differences. Charles Cheadle of Cesar Chavez School says, "Boys are not so afraid they might do something that will harm the computer, whereas girls are afraid they might break it somehow."
Six years ago, the software company Purple Moon noticed that girls' computer usage was falling behind boys. Karen Gould says, "The number one reason girls told us they don't like computer games is not because they're too violent, or too competitive. Girls just said they're incredibly boring."
Purple Moon says it found what girls want, characters they can relate to and story lines relative to what's going on in their own lives. Karen Gould of Purple Moon Software says, "What we definitely found from girls is there is no intrinsic (内在的) reason why they wouldn't want to play on a computer; it was just a content thing."
The sponsor of the study says it all boils down to this, the technology gender gap that separates the girls from the boys must be closed if women are to compete effectively with men in the 21st century.
In this sixth grade classroom, you would find ______.
A．only boys are allowed to use the computers
B．only girls are allowed to use the computers
C．no computers in the classroom
D．both boys and girls are allowed to use the computers
Preparing for Computer Disasters
Fires，power surges，and floods，they're all facts of life.We read about them in the morning paper and see them on the evening news．We sympathize with the victims and commiserate over their bad luck．We also shake our heads at the digital consequences-melted computers，system failures，destroyed data.Yet，somehow，many of us continue to live by that old mantra of denial：“It won't happen to me．”Well，the truth is，at some point you'll probably have to deal with at least one disaster．That's just how it goes，and in most aspects of our lives we do something about it．We buy insurance．We stow away provisions．We even make disaster plans and run drills．But for some reason，computer disaster recovery is a blind spot for many of us．It shouldn't be．Home computers contain some of our most important information，both business and personal，and making certain our data survives a disaster should be a priority．Moreover，even the smallest disaster can be a serious disruption．Personal computers have become an integral part of the smooth-running household. We use them to communicate, shop, and do homework, and they're even more vital to home office users. When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward. With a good offsite storage plan and the right tools, you can bounce back quickly and easily from minor computer disasters. And, should a major calamity strike, you can rest assured your data is safe.
Offsite Storage: Major Disasters
House fires and floods are among the most devastating causes of personal computer destruction. That's why a solid offsite backup and recovery plan is essential. Although many home users faithfully back up their hard drives, many would still lose all their data should their houses flood or burn. That's because they keep their backups in relatively close to their computers. Their backup disks might not be in the same room as their computers-tucked away in a closet or even the garage-but they're not nearly far enough away should a serious disaster strike. So, it's important to back up your system to a removable medium and to store it elsewhere.
There are many ways to approach offsite storage. It starts with choice of backup tools and storage medium. Disaster situations are stressful, and your recovery tools shouldn't add to that stress. They must be dependable and intuitive, making it easy to schedule regular backups and to retrieve files in a pinch. They must also be compatible with your choice of backup medium. Depending on your tools, you can back up to a variety of durable disk types--from CDs to Jaz drives to remote network servers. Although many of these storage media have high capacity, a backup tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads.
Once you select your tools and a suitable medium, you need to find a remote place to store your backups. The options are endless. However, no matter where you choose, be sure the site is secure, easily accessible, and a good distance away from your home. You may also want to consider using an Internet-based backup service. More and more service providers are offering storage space on their servers, and uploading files to a remote location has become an attractive alternative to conventional offsite storage. Of course, before using one of these services, make certain you completely trust the service provider and its security methods. Whatever you do, schedule backups regularly and store them far away from your home.

听力原文：M: Excuse me. I wonder if you could help me.
W: What can I do for you？
M: Well, I'm working on a term paper about the influence of television on American presidential elections.
W: Have you ever been to the main library？
M: Yes, I've found a few useful books there, but the reference librarian at the main library suggested that the library here at the graduate school have more specialized materials.
W: Okay. It depends on what you want. We do subscribe to a large number of journals. Since you're working on such a broad topic you'll probably have to do a lot of digging.
M: Do you think I can get something relevant here？
W: It may take some time, but you'll be able to find many articles relevant to your topic. We also have quite a few newspapers on microfilm.
M: I think I've come to the right place. How can I find out which journals you have？
W: There's a list of all of them. But if you want to search by author or by subject you can use one of the computers over there. Everything we have is in there.
M: What if I run across a reference to a research study that isn't available here？
W: You can request any outside materials just by typing your request into the computer.
M: You mean you can get materials from other universities？
W: Not only from other universities, but from virtually any public or private library in the United States. The only limitation is that outside materials can't be checked out.
