第1空答案是：
M: It's coming along. But I've been staring at the computer screen for hours and my eyes hurt.
W: Yeah Typing the words on the screen really make your eyes dry and tired. You should take a break.
M: I can't. The deadline is approaching.
W: You know, I read about computers and eye problems recently. The article says that they are usually caused by not blinking your eyes enough.
M: Blinking？ I thought I just needed new glasses.
W: when you blink, the movement of closing and opening your eyes, even though it happens really fast relaxes your eyes.
M: That makes sense.
W: People using computer tends to stare at the screen and blink less often than they normally would.
M: That is what I am doing. And I am suffering from the dry eyes.
W: That is one of the typical symptoms. M: But what does it have to do with the computer？
W: The article I read about the office workers found that the workers averagely blink 22 times a minute when relaxed But just 7 times a minute while looking at the text on a computer screen.
M: Wow That's quite a difference.
W: Yeah. So you need to blink your eyes and take a break from the computer
M: I wonder if using some kind of eye-drops will make me feel better.
W: That might help.But the best prescription is to take a break and rest your eyes

A．Something goes wrong with his computer.
B．He can not finish the documents in time.
C．The computer screen is hurting his eyes.
D．He can not understand the article.
It's easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers.
Of course, we have no statistics on crimes that go undetected. But it's disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may be the victims of uncommonly bad luck.
For example, a certain keypunch operator complained of having to stay overtime to punch extra cards. Investigation revealed that the extra cards she was being asked to punch were for dishonest transaction. In another case, dissatisfied employees of the thief tipped off the company that was being robbed.
Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met.
Why？ Because company executives are afraid of the bad publicity that would result if the public found out that their computer has been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company's executives, accountants, and security staff. And so another computer criminal departs with just there commendations he needs to continue his crimes elsewhere.
It can be concluded from the first paragraph that______.
A．it is still impossible to detect computer crimes today
B．computer crimes are very serious in the operation of financial institutions
C．computer criminals can escape punishment because they can't be detected
D．people commit computer crimes at the request of their company

Internet
Almost everyone with or without a computer is aware of the latest technological revolution destined to change forever the way in which humans communicate, namely, the Information Superhighway, best exemplified by the ubiquitous Internet. Already, millions of people around the world are linked by computer simply by having a modem and an address on the "Net", in much the same way that owning a telephone links us to almost anyone who pays a phone bill. In fact, since the computer connections are made via the phone line, the Internet can be envisaged as a network of visual telephone links.
The World Wide Web, an enormous collection of Internet addresses or sites, all of which can be accessed for information, has been mainly responsible for the increase in interest in the Internet in the 1990s. Before the World Wide Web, the "Net" was comparable to an integrated collection of computerized typewriters, but the introduction of the "Web" in 1990 allowed not only text links to be made but also graphs, images and even video.
A Web site consists of a "home page", the first screen of a particular site on the computer to which you are connected, from where access can be headed to other subject related "pages" (or screens)at the site and on thousands of other computers all over the world. This is achieved by a process called "hypertext". By clicking with a mouse device on various parts of the screen, a person connected to the "Net" can go traveling, or "surfing" through a web of pages to locate whatever information required.
Anyone can set up a site, promoting your club, your institution, your company's products or simply yourself. And what is more, information on the Internet is not owned or controlled by any organization. It is, perhaps, true to say that no one and therefore everyone owns the "Net". Because of the relative freedom of access to information, the Internet has often been criticized by the media as a potentially hazardous tool in the hands of young computer users. This perception has proved to be largely false however, and the vast majority of users both young and old get connected with the Internet for the dual purposes for which it was intended--discovery and delight.
Everyone is aware of the Information Superhighway.
