Computer Mouse
The basic computer mouse is an amazingly clever invention with a relatively simple design that allows us to point at things on the computer and it is very productive. Think of all the things you can do with a mouse like selecting text for copying and pasting, drawing, and even scrolling on the page with the newer mice with the wheel. Most of us use the computer mouse daily without stopping to think how it works until it gets dirty and we have to learn how to clean it. We learn to point at things before we learn to speak, so the mouse is a very natural pointing device. Other computer pointing devices include light pens, graphics tablets and touch screens, but the mouse is still our workhorse.＜br＞
The computer mouse was invented in 1964 by Douglas Engle hart of Stanford University. As computer screens became more popular and arrow keys were used to move around a body of text, it became clear that a pointing device that allowed easier motion through the text and even selection of text would be very useful. The introduction of the mouse, with the Apple Lisa computer in 1983,really started the computer public on the road to relying on the mouse for routine computer tasks.＜br＞
How does the mouse work？ We have to start at the bottom, so think upside down for now. It all starts with the mouse ball. As the mouse ball in the bottom of the mouse rolls over the mouse pad, it presses against and turns two shafts. The shafts are connected to wheels with several small holes in them. The wheels have a pair of small electronic light-emitting devices called light-emitting diodes (LED) mounted on either side. One LED sends a light beam to the LED on the other side. As the wheels spin and a hole rotates by, the light beam gets through to the LED on the other side. But a moment later the light beam is blocked until the next hole is in place. The LED detects a changing pattern of light, converts the pattern into an electronic signal, and sends the signal to the computer through wires in a cable that goes out of the mouse body. This cable is the tail that helps give the mouse its name. The computer interprets the signal to tell it where to position the cursor on the computer screen.＜br＞
So far we have only discussed the basic computer mouse that most of you probably have or have used. One problem with this design is that the mouse gets dirty as the ball rolls over the surface and picks up dirt. Eventually you have to clean your mouse. The newer optical mice avoid this problem by having no moving parts.
Most computer users want to know how the computer mouse works. 查看材料

Media and Current Events
The media can impact current events. As a graduate student at Berkeley in the 1960s, I remember experiencing the events related to the People’s park that were occurring on campus. Some of these events were given national media coverage in the press and on TV. I found it interesting to compare my impressions of what was going on with perceptions obtained from the new media. I could begin to see events of that time feed on news coverage. This also provided me with some healthy insights into the distinctions between these realities.
Electronic media are having a treater impact on the people’s lives every day. People gather more and more of their impressions from representations. Television and telephone communications are linking people to a gloable village,or what one writer calls the electronic city. Consider the information that televison trings into your home everyday. Consider also the contact you have with others simply by using telephone. These media extend your conscious-ness and your contact. For example, the video coverage of the 1989 San Francisco earthquake focused on “live action”such as the fires for the rescue efforts. This gave the riewer the impression of total. Disaster. Television coverage of the Iraqi War also developed an immediacy. CNN reported events as they happened. This coverage was distributed worldwide. Although most people were far away from these events, they developed some perception of these realities.
In 1992, many people watched in horror as riots broke out on a sad Wednesday evening in Los Angeles,seemingly fed by video coverage from helicopters. This events was triggered by the verdict(裁定)in the Rodney King beating. We are now in an age where the public can have access to information that enables it to make its own judgments, and most people, who had seen the video of this beating, could not understand how the jury(陪审团)was able to acquit (宣布无罪) the policemen involved.
Media coverage of events as they occur also provides powerful feedback that influences events. This can have harmful results, as it seemed on that Wednesday night in Los Angeles. By Friday night the public got to see Rodney King on television pleading,“Can we all get along？” By Saturday, television seemed to provide positive feedback as the Los Angeles riot turned out into a rally for peace. The television showed thousands of people marching with banners and cleaning tools.
Because of that, many more people turned out to join the peaceful event they saw unfolding(展开)on television. The real healing, of course, will take much longer, but electronic media will continue to be a part of that process.

第9题
The agency's devices monitor a great deal of telephone circuits, cable lines and the microwave transmissions that carry an increasing share of both spoken and written communications. Computers are programed to watch for "trigger" words or phrases indicating that a message might interest intelligence analysis, when the trigger is pulled, entire messages are tape-recorded or printed out.
That kind of eavesdropping is, however, relatively simple compared with the breakthroughs that lie ahead in the field of snoopery. Already it is technically feasible to "bug" an electric typewriter by picking up its feeble electronic emissions from a remote location and then change them into words. And some scientists believe that it may be possible in the future for remote electronic equipment to intercept and "read" human brain waves.
Where such capabilities exist, so too does the potential for abuse. It is the old story of technology rushing forward with some new wonder, before the men who supposedly control the machines have found how to prevent the machines from controlling them.
Which is the best title for the passage？
A．Fight against Eavesdropping.
B．A New Breakthrough.
C．No Place to Hide.
D．An Impassioned Warning.
