单选题 Psychologist George Spilich and colleagues at Washington College in Chestertown, Maryland, decided to find out whether, as many smokers say, smoking helps them to "think and concentrate". Spilich put young non-smokers, active smokers and smokers deprived(被剥夺)of cigarettes through a series of tests. In the first test, each subject(试验对象)sat before a computer screen and pressed a key as soon as he or she recognized a target letter among a grouping of 96. In this simple test, smokers, deprived smokers and non-smokers performed equally well. The next test was more complex, requiring all to scan sequences of 20 identical letters and respond the instant one of the letters was transformed into a different one. Non-smokers were faster, but under the stimulation of nicotine(尼古丁), active smokers were faster than deprived smokers. In the third test of short-term memory, non-smokers made the fewest errors, but deprived smokers committed fewer errors than active smokers. The fourth test required people to read a passage, then answer questions about it. Non-smokers remembered 19 percent more of the most important information than active smokers, and deprived smokers bested those who had smoked a cigarette just before testing. Active smokers tended not only to have poorer memories but also had trouble separating important information from insignificant details. "As our tests became more complex," sums up Spilich, "non-smokers performed better than smokers by wider and wider margins, " He predicts," smokers might perform adequately at many jobs—until they got complicated. A smoking airline pilot could fly adequately if no problems arose ,but if something went wrong, smoking might damage his mental capacity. "

单选题 Increasingly, over the past ten years, people—especially young people—have become aware of the need to change their eating habit, because much of the food they eat, particularly processed foods, is not good for health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers, widely used in farming today. Natural foods, for example, are vegetable, fruit and grain which have been grown in soil and are rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount—but not the quality—of foods grown in commercial farming areas. Natural foods also include animals which have been allowed to feed and move freely in healthy pastures. Compare this with what happens in the mass production of poultry: there are battery farm, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins. There are other aspects of healthy eating which are now receiving increasing attention from experts on diet. Take, for example, the question of sugar. This is actually a nonessential food! Although a natural alternative, such as honey, can be used to sweeten food if it is necessary, we can in fact do without it, It is not that sugar is harmful in itself. But it does seem to be addictive: the quantity we use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is to provide us with energy, in the form of calories. There are no vitamins in it, no minerals, and no fibre. It is significant that nowadays fibre is considered to be an important part of a healthy diet. In white bread, for example, the fibre has been removed. But it is present in unrefined flour and of course in vegetables. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetables, certain diseases are comparatively rare. Hence the emphasis is placed on the eating of wholemeal bread and more vegetables by modern experts in "healthy eating".

单选题Change is the principle--and the process--that enables us to move on and upward growth and change, of continuous improvement. To make meaningful progress, we need to consider one other aspect of change as it is used only by human our thought. In the words of Madame, "The voice of thought is so soft that it is easy to forget about it, but it is also so clear that it is impossible to misunderstand it." Just as the education of nerve is most important to the excellent athlete and education of the mind is vital to the scholar, education of the thought is vital to the truly highly effective person. Training and educating the thought, however, requires even greater concentration, more balanced discipline, more consistently honest living. It requires regular feasting on inspiring literature, thinking noble thoughts and, above all, living in harmony with its still small voice. Just as junk food and lack of exercise can ruin an athlete's condition, those things that are not decent, crude, or unhealthy can lead to an inner darkness and make us wonder "What is right and wrong?" In the words of Dag Hammarskjold, You cannot play with the animal in you without becoming wholly animal, play with falsehood without losing your right to truth, play with cruelty without losing your sensitivity of mind. He who wants to keep his garden tidy doesn't reserve a plot for weeds. Once we are self-aware, we must choose purposes and principles to live by; otherwise the hole will be filled, and we will lose our self-awareness and become like groveling animals that live mainly for survival. And there is no easy way in developing them. The Law of the Harvest governs; we will always reap what we sow--no more, no less. I believe that as we grow and develop, an increasingly educated thought will push us along the path of personal freedom, security, wisdom, and power. Moving upward requires us to learn, commit, and do on increasingly higher planes. To keep progressing, we must learn, commit, and do--learn, commit, and do--and learn, commit, and do again.

单选题{{B}}Text 3{{/B}} You're busy filling out the application form for a position you really need. Let's assume you once actually completed a couple of years of college work or even that you completed your degree. Isn't it tempting to lie just a little, to claim on the form that your diploma represents a Harvard degree? Or that you finished an extra couple of years back at State University? More and more people are turning to utter deception like this to land their job or to move ahead in their careers, for personnel officers, like most Americans, value degrees from famous schools. A job applicant may have a good education anyway, but he or she assumes that chances of being hired are better with a diploma from a well-known university. Registrars at most well-known colleges say they deal with deceitful claims like these at the rate of about one per week. Personnel officers do check up on degrees listed on application forms, then. If it turns out that an applicant is lying, most colleges are reluctant to accuse the applicant directly. One Ivy League school calls them "impostors (骗子)"; another refers to them as "special cases". One well-known West Coast school, in perhaps the most delicate phrase of all, says that these claims are made by"no such people". To avoid outright (彻底的) lies, some job-seekers claim that they "attended" or "were associated with" a college or university. After carefully checking, a personnel officer may discover that "attending" means being dismissed after one semester. It may be that"being associated with" a college means that the job-seeker visited his younger brother for a football weekend. One school that keeps records of false claims says that the practice dates back at least to the turn of the century—that's when they began keeping records, anyhow. If you don't want to lie or even stretch the truth, there are companies that will sell you a {{U}}phony{{/U}} diploma. One company, with offices in New York and on the West Coast, will put your name on a diploma from any number of nonexistent colleges. The price begins at around twenty dollars for a diploma from "Smoot State University". The prices increase rapidly for a degree from the "University of Purdue". As there is no Smoot State and the real school in Indiana is properly called Purdue University, the prices seem rather high for one sheet of paper.

单选题{{B}}Text 2{{/B}} SMS (Short Message Service) gradually becomes the main service for cell phone users for its great charming. In addition, the development of mobile communications technology and service has created favorable condition for SMS. For example, MMS, multi-media messaging service, is a new type of message service on the basis of SMS. It allows transmission of multi-media messages between cell phone and computer, as well as between cell phones. Communication with SMS is quite convenient. You can write a message after carefully thinking what you want to say with many words without worrying about money. Actually, SMS enjoys the absolute majority utilization among mobile service. In China, the number of short message transmitted is 2,200 billion in 2003. People, however, feel angry and anxious sometimes while enjoying SMS. More and more rubbish short messages that contain such content as erotic, gambling, or advertising are sent to cell phone users, which seriously violated the user's privacy. Because the sender of these rubbish short messages do not take into account whether people need them or not, and do not get the permission from users to transmit these rubbish short messages to them. As we know, everyone has the right to communication freely with other people, and the right to refuse communication with people they don't like to. But these rights were not guaranteed in SMS. Users do not receive rubbish short messages on a voluntary basis. If you fell angry and disgusted with some rubbish message to your cell phone, and do not want to see it again, that means such message is in contradiction with your wish, and violates your privacy. MMS also promote the transmission of unhealthy information on the Internet from computer to cell phone, which must extend the scope and influence of rubbish short message. The rapid development of mobile communications may suffer a lot if there is no change in the way of transmitting SMS. More and more users of cell phone are disturbed by rubbish short messages, and their privacy is violated by mobile communications service, which is also not a benefit for the development of mobile communications service.
