单选题In 1971 the Royal College of Physicians decided to take action on the problem of smoking and health. They formed an organization called Action on Smoking and Health -- ASH. Its aims are to make people aware of the dangers of smoking and to help those people who do smoke to give up. As part of its campaign to make people see how smoking damages us all, both as individuals and as members of society, ASH has gathered together some every convincing facts and figures. For in stance, smoking is very harmful to industry. Nearly 50 million working days are lost in Britain every year due to smoking -- at least four times the number of days lost in strikes. And the cost of treating people suffering from smoking related disease is around ￡ 100 million each year. But the human suffering which smoking causes is far more serious than the economic price which society has to pay. 95% of those who suffer from bronchitis are smokers. It has been estimated that 20% of all cigarette smokers become disabled by chronic bronchitis and may eventually die of the disease. Over 20,000 people die of bronchitis every year. Lung cancers kill more people than any other types; of cancers; 90% of them are caused by smoking. With coronary heart disease the risk of death is 2 to 3 times as great in smokers as in non - smokers and this disease is now the major cause of death in Britain. Bronchitis, lung cancer and coronary heart disease arc the three most serious reasons for not smoking but there are other masons which are also important. The message from ASH is clear -- if you do smoke you should give up now and if you don't smoke then you should not start -- ever.

单选题Arabs consider it extremely bad manners to start talking business immediately. Even the busiest government officials always take extra time to be polite and offer refreshments. No matter how busy you are, you should make time for this hospitality. The conference visit is a way of doing business throughout the Arab world. Frequently, you will have to discuss your business in the presence of strangers, who may or may not have anything to do with your business. Do not be surprised if your meeting is interrupted several times by people who come into the room unannounced, whisper, or speak softly to the person with whom you are talking, and leave. Act as though you do not hear, and never show displeasure at being interrupted. When an Arab says "yes", he may mean "maybe". When he says "maybe", he probably means "no". You will seldom get a direct "no" from an Arab because it is considered impolite. Instead of "no", he will say "inshallah", which means, "if Allah wills it". On the other hand, "yes" does not necessarily mean "yes". A smile and a slow nod might seem like an agreement, but in fact, your host is being polite. An Arab considers it impolite to disagree with a guest.

单选题Some people argue that self-plagiarism(自我剽窃) is impossible by definition because plagiarism is theft and people cannot steal from their own work. But, this is not correct in law. And there are circumstances, such as insurance fraud(保险欺诈), etc, when it is possible to steal from oneself. Self-plagiarism, however, must be carefully distinguished from the recycling of one's work that to a greater or lesser extent everyone legally does. Self-plagiarism in academic (学术的) publications is a gray area. However, many universities indirectly recognize the practice as deceptive. They publish rules preventing students from handing in basically the same essay for credit in different courses. There are also rules against someone handing in the same graduate thesis to different universities. Among established academics, self-plagiarism is a problem. It means basically the same article or book is handed in on more than one occasion for salary raising or promotion. Like all plagiarism the essence of self-plagiarism is the author attempts to cheat the reader. This happens when no indication is given that the work is being recycled or when an effort is made to disguise the original text. For example, an author just makes cosmetic changes to make the same article, chapter, or book look different. But actually it remains unchanged in its central argument. In this case, disguising a text occurs. Authors change such things as paragraph breaks, capitalization, or the substitution of technical terms in different languages. What he has done is to make readers believe they are reading something completely new. This practice is self-plagiarism.
