单选题{{B}}Text 3{{/B}} Everyone knows how the story of Cinderella ends, but did you ever really think about how she spent her days before she met the prince? Her daily routine was not fascinating. She did everything from sweeping the floor to cooking the meals. If someone had asked Cinderella," Are there any kinds of household work that you particularly hate?" She probably would have answered," Why, none, of course. Housework is my duty!" In the real world, however, most people have definite dislikes for certain sorts of household work. Two of these tasks are ironing clothes and washing dishes. Ironing clothes is most hated because it is not a task that can be completed quickly or thoughtlessly. Each piece of clothing must be handled individually, so ironing a basket of laundry can take hours! After ironing a piece of clothing with great caution, which requires smoothing out the fabric, and following the seams, you need to place it on a hanger as soon as possible. If you do not follow these directions carefully, it might become wrinkled and you have to start over. Perhaps that is why ironing is not a favorite thing to do. It calls for extreme attention to detail from beginning to end. Another household job that many people dislike is washing dishes. Of course, some people claim that this work is no longer a problem because we have dishwashers now! However, no one would argue that dishes, silverware, and especially pots and pans washed in a dishwasher don't come out as clean as they do when washed by hand. For this reason, many of us continue to wash our dishes by hand, but we are not necessarily happy doing it. Cleaning dishes is a job that not only takes a lot of energy but also requires the patience to wash and dry them. In addition, unlike ironing clothes, washing dishes is a thing that usually must be done every day. I don't know how Cinderella felt about this particular task, but I believe that most people hate it as much as I do.

Mark your answer on ANSWER SHEET.{{B}}Text 1{{/B}} Drunken driving—sometimes called America's socially accepted form of murder—has become a national epidemic. Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250 000 over the past decade. A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American macho image and judges were lenient in most courts, but the drunken slaughter has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant. Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18-20-year-old drivers, more than doubled, so the state recently upped it back to 21. Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programmes to help young people to develop "responsible attitudes" about drinking and teach them to resist peer pressure to drink. Tough new laws have led to increased arrests and tests and, in many areas already, to a marked decline in fatalities. Some states are also penalising bars for serving customers too many drinks. A tavern in Massachusetts was fined for serving six or more double brandies to a customer who was "obviously intoxicated" and later drove off the road, killing a nine-year-old boy. As the fatalities continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years of national prohibition of alcohol that began in 1919, what President Hoover called the "noble experiment". They forget that legal prohibition didn't stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.

单选题Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives and more recently, rubber and plastic and that was where we stuck, in surgical instrument terms; for many years. In the 1960s a new tool was developed, one which was, first of all, to be of great practical use to the armed forces and industry, but which was also, in time, to revolutionize the art and science of surgery. The tool is the laser and it is being used by more and more surgeons all over the world, for a very large number of different complaints. The word "laser" means: light amplification by stimulated emission of radiation. As we all know, light is hot, any source of light — from the sun itself down to a humble match burning — will give warmth. But light is usually spread out over a wide area. The light in a laser beam, however, is concentrated. This means that a light with no more power than that produced by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam. Experiments with these pinpoint beams showed researchers that different energy sources produce beams that have a particular effect on certain living cells. It is now possible for eye surgeons to operate on the back of the human eye without harming the front of the eye, simply by passing a laser beam right through the eyeball. No knives, no stitches, no unwanted damage — a true surgical wonder. Operations which once left patients exhausted and in need of long period of recovery time now leave them feeling relaxed and comfortable. So much more difficult operations can now be tried. The rapid development of laser techniques in the past ten years has made it clear that the future is likely to be very exciting. Perhaps some cancers will be treated with laser in a way that makes surgery not only safer but also more effective. Altogether, tomorrow may see more and more information coming to light on the diseases which can be treated medically.
