单选题{{B}}Text 4{{/B}} The initial impact of computers was in the area of entertainment. If you walked by a video arcade in the early 1980s, you could not have failed to notice that the use of video games was growing at what some considered an alarming rate. In 1981 the movie industry grossed $3 billion, video games took in an estimated $6 billion. That gives you some idea of just how big the computer industry bad become. Video games employ the same technology as personal computers, and indeed many who bought personal computers did so primarily for playing games at home, thus saving their quarters. Though video games are not as popular as they were a few years ago, they did provide consumers with their first real reason to buy PCs. A more recent computer innovation, desktop publishing, supplies one good reason for those who write for a living to buy a PC. Desktop publishing is a deceptively simple description for an extremely complex group of hardware and software tools. You can now write text, edit text, draw illustrations, incorporate photographs, design page layouts, and print a finished document with a relatively inexpensive computer and laser printer. Although the new technology offers new freedom, there is a price to be paid for this freedom. With total control comes total responsibility. In fact, the issue of social responsibility in our new computer age has long been a topic of debate among computer enthusiasts. Some people are concerned with the long-term social effects of the so-called computer revolution. Ironically, many PC pioneers who built and marketed the first machines were 60s-style advocates of social change. They claim that while personal computer technology has the potential to make society more equal, it's having the opposite effect since upper-middle-class people can afford them and lower-class people cannot. In addition, the ways that computers are used to monitor the activities of their users have evoked anxiety about the machine. Over 7 million Americans now have their work paced, controlled, and monitored by computers. A computer is more restrictive and powerful in the way it controls people than the old-fashioned assembly line. This can lead to what some have called "tech-stress". Irritated eyes, back problems, and other physical symptoms have also been associated with the extensive use of computers. Although the personal computer may not have had the impact some predicted a decade ago, the combination of computer technology with satellites and cable does promise innovations in the mass media that would have seemed astonishing just a few short years ago.

单选题The war was the most peaceful period of my life. The window of my bedroom faced southeast. My mother had curtained it, but that had small effect. I always woke up with the first light and, with all the responsibilities of the previous day melted, felt myself rather like the sun, ready to shine and feel joy. Life never seemed so simple and clear and full of possibilities as then. I stuck my feet out under the sheets--I called them Mrs. Left and Mrs. Right--and invented dramatic situations for them in which they discussed the problems of the day. At least Mrs. Right did; she easily showed her feelings, but I didn't have the same control of Mrs. Left, so she mostly contented herself with nodding agreement. They discussed what Mother and I should do during the day, what Santa Claus should give a fellow for Christmas, and what steps should be taken to brighten the home. There was that little matter of the baby, for instance. Mother and I could never agree about that. Ours was the only house in the neighborhood without a new baby, and Mother said we couldn't afford one till Father came back from the war because it cost seventeen and six. That showed how foolish she was. The Geneys up the road had a baby, and everyone knew they couldn't afford seventeen and six. It was probably a cheap baby, and Mother wanted something really good, but I felt she was too hard to please. The Geneys' baby would have done us fine. Having settled my plans for the day, I got up, put a chair under my window, and lifted the frame high enough to stick out my head. The window overlooked the front gardens of the homes behind ours, and beyond these it looked over a deep valley to the tall, red-brick house up the opposite hillside, which were all still shadow, while those on our side of the valley were all lit up, though with long storage shadows that made them seem unfamiliar, stiff and painted. After that I went into Mother's room and climbed into the big bed. She woke and I began to tell her of my schemes. By this time, though I never seem to have noticed it, I was freezing in my nightshirt, but I warmed up as I talked until the last frost melted. I fell asleep beside her and woke again only when I heard her below in the kitchen, making breakfast.

单选题Some modern anthropologists hold that biological evolution has shaped not only human morphology but also human behavior. The role those anthropologists ascribe to evolution is not of dictating the details of human behavior but one of imposing constraints-ways of feeling, thinking, and acting that "come naturally" in archetypal situations in any culture. Our "frailties" --emotions and motives such as rage, fear, greed, gluttony, joy, lust, love--may be a very mixed assortment, but they share at least one immediate quality: we are, as we say, "in the grip" of them. And thus they give us our sense of constraints. Unhappily, some of those frailties--our need for ever-increasing security among them--are presently maladaptive. Yet beneath the overlay of cultural detail, they, too, are said to be biological in direction, and therefore as natural to us as are out appendixes. We would need to comprehend thoroughly their adaptive origins in order to understand how badly they guide us now. And we might then begin to resist their pressure.
