单选题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. The computer mouse was invented in 1964 by Douglas Englehart 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. 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. 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.

单选题The Influence of Western Movie Why does the Western movie especially have such a hold (影响) on our inclination? Chiefly, because it offers serious insights into the problem of violence such as can be found almost nowhere else in our culture. One of the well-known peculiarities of modem civilized opinion is its refusal to acknowledge the value of violence. This refusal is a virtue, but like many virtues it involves a certain deliberate blindness and it encourages hypocrisy (虚伪). We train ourselves to be shocked or bored by cultural images of violence, and our very concept of heroism tends to be a passive one. We are less drawn to the brave young men who kill large numbers of our enemies than to the heroic prisoners who endure torture without surrendering. And in the criticism of popular culture, the presence of images of violence is often assumed to be in itself a sufficient ground for condemnation. These attitudes, however, have not reduced the element of violence in our culture but have helped to free it from morn control by letting it take on the air of "liberation". The celebration of acts of violence is left more and more to the irresponsible. The gangster (匪徒) movie, with its numerous variations belongs to a cultural "underground" which praises violence aid sets it against all our higher social attitudes. It is a more "modern" style than the Western movie, perhaps even more profound, because it confronts industrial society on its own ground-the city and because, like much of our advanced art, it gains its effects by a coarse insistence on its own narrow logic. But it is anti-social resting on fantasies of irresponsible freedom. If we are brought finally to concede to the denial of these fantasies, it is only because they have been shown to be dangerous, not because they have given way to higher values of behavior. In war movies, certainly, it is possible to present violence within a framework of responsibility. But there is the disadvantage that modern war is a co-operative enterprise in which violence is largely impersonal and heroism belongs to the group more than to the individual. The hero of a war movie is most often simply a leader supposed to be brave; you are supposed to get the job done and stay alive (this too, of course, is a kind of heroic posture, but a new and "practical" one). At its best, the war movie may represent a more civilized point of view than the Western, and if it were not continually spoiled by ideological sentimentality we might hope to find it developing into a higher form of drama. But it cannot supply the values we seek in the Western.

单选题A Powerful Influence There can be no doubt at all that the Internet has made a huge difference to our lives. Parents are worried that children spend too much time playing on the Internet, hardly 1 doing anything else in their spare time.

单选题{{B}}第二篇{{/B}} {{B}} Ford's Assembly Line{{/B}} When it comes to singling out those who have made a difference in all our lives, you cannot overlook Henry Ford. A historian a century from now might well conclude that it was Ford who most influenced all manufacturing, everywhere, even to this day, by introducing a new way to make cars—one, strange to say, that originated in slaughterhouses (屠宰场). Back in the early 1900%, slaughterhouses used what could have been called a "disassembly line". Ford reversed this process to see if it would speed up production of a part of an automobile engine called a magneto. Rather than have each worker completely assemble a magneto, one of its elements was placed on a conveyer, and each worker, as it passed, added another component to it, the same one each time. Professor David Hounshell of the University of Delaware, an expert on industrial development, tells what happened: "The previous day, workers carrying out the entire process had averaged one assembly every 20 minutes. But on that day, on the line, the assembly team averaged one every 13 minutes and 10 seconds per person." Within a year, the time had been reduced to five minutes. In 1913, Ford went all the way. Hooked together by ropes, partially assembled vehicles were towed (拖，拉) past workers who completed them' one piece at a time. It wasn't long before Ford was turning out several hundred thousand cars a year, a remarkable achievement then. And so efficient and economical was this new system that he cut the price of his cars in half, to $260, putting them within reach of all those who, up until that time, could not afford them. Soon, auto makers over the world copied him. In fact, he encouraged them to do so by writing a book about all of his innovations, entitled Today and Tomorrow. The Age of the Automobile has arrived. Today, aided by robots and other forms of automation (自动化), everything from toasters to perfumes is made on assembly lines.

单选题Moderate Earthquake Strikes England! A moderate earthquake struck parts of southeast England on 28 April 2007, toppling chimneys from houses and rousing residents from their beds. Several thousand people were left without power in Kent County. One women suffered minor head and neck injuries. "It felt as if the whole house was being slid across like a fun-fair ride," said the woman. The British Geological Survey said the 4.3-magnitude quake struck at 8 ~ 19 a.m. and was centered under the English Channel, about 8.5 miles south of Dover and near the entrance to the Channel Tunnel. Witnesses said cracks appeared in wails and chimneys collapsed across the county. Residents said the tremor had lasted for about 10 to 15 seconds. "I was lying in bed and it felt as if someone had just got up from bed next to me. " Said Hendrick van Eck, 27, of Canterbury about 60 miles southeast of London. "I then heard the sound of cracking, and it was getting heavier and heavier. It felt as if someone was at the end of my bed hopping up and down. " There are thousands of moderate quakes on this scale around the world each year, but they are rare in Britain. The April 28 quake was the strongest in Britain since 2002 when a 4.8-magnitude quake struck the central England city of Birmingham. The country's strongest earthquake took place in the North Sea in 1931 ,measuring 6.1 on the Richter scale. British Geological Survey scientist Roger Musson said the quake took place on 28 April in an area that had seen several of the biggest earthquakes ever to strike Britain, including one in 1580 that caused damage in London and was felt in France. Musson predicted that it was only a matter of time before another earthquake struck this part of England. However. people should not be scared too much by this prediction, Musson said, as the modern earthquake warning system of Britain should be able to detect a forthcoming quake and announce it several hours before it takes place. This would allow time for people to evacuate and reduce damage to the minimum.
