单选题Now medical researchers are discovering a truism: "alcohol and tobacco do not mix." These two substances, both dangerous to health, act synergistically, each making the other more powerful and thereby causing worse damage than either would do alone. Because of this interaction, the person who both smokes and drinks heavily may be at a greater risk of becoming ill than one who drinks like a fish, but never smokes or who smokes like a chimney, but never drinks. To get an idea of how this synergism may work, consider what happens when a smoker lights up a cigarette. With each puff he inhales at least 4,000 different chemicals. These include toxic hydrogen-cyanide, carbon monoxide and nitrogen-dioxide gases, and four dozen compounds such as benzo pyrene and radioactive polonium 210. All are known as carcinogens. Most chemical vapors in tobacco smoke get deposited in the mouth, nose, throat and lungs in a coating called tar. It is in this tar that most of the cancer--inducing potential of tobacco smoke lies. Then in a scenario typical of chronic heavy drinkers--most of whom also smoke--our smoker feels thirsty and washes down that smoke coating in his mouth and throat with whisky. The alcohol in his drink is not in itself a carcinogen, but it may act as a solvent, dissolving the tar-taped tobacco poisons, and easing the transport of carcinogens across membranes. Our smoker continues to drink. Soon he lights another cigarette and inhales deeply. Behind his embattled lungs, meanwhile, his liver has gone on full alert to save his life. The three-pound chemical factory, which cleans most toxins from the bloodstream, reacts to alcohol as a foreign substance and metabolizes 95 percent of it into other chemicals. But in turning its energy to clearing just one-half ounce of pure alcohol--the amount in a standard drink--per hour from our drinking smoker's blood, the liver's other metabolic functions suffer a sharp decrease. Poisons from tobacco smoke that otherwise would be removed from his blood within minutes are now allowed to flood his body for hours or days, depending on how much alcohol the liver must dispose of. The person who smokes one or two packs of cigarettes a day loses on average six to eight percent of his blood's oxygen carrying capacity. If our heavy smoker's use of alcohol has led to alcoholism, he is probably malnourished. This malnourishment compounds problems he is having with insufficient oxygen. His brain cells are dying from it. The synergistic effect of alcohol and tobacco may deliver a powerful blow to the cardiovascular system as well as the upper respiratory tract. For those prone to hypertension who drink more than two ounces of alcohol a day, high blood pressure is common and with it the increased risk of stroke and heart attack. For hypertensives who combine smoking and drinking, the risks are even greater.

单选题The great question that this paper will, but feebly, attempt to answer is, what is the creative process? Though much theory has accumulated, little is really known about the power that lies at the bottom Of poetic creation. It is true that great poets and artists produce beauty by employing all the powers of personality and by fusing emotions, reason, and intuitions. But what is the magical synthesis that joins and arranges these complex parts into poetic unity? John L. Lowes, in his justly famous "The Road to Xanadu", developed one of the earliest and still generally acceptable answers to this tantalizing question. Imaginative creation, he concludes, is a complex process in which the conscious and unconscious minds jointly operate. "There is... the Deep Well with its chaos of fortuitously blending images; but there is likewise the Vision which sees shining in and through the chaos of the potential lines of Form, and with the Vision, the controlling Will, which gives to that potential beauty actuality." The Deep Well is the unconscious mind that is peopled with the facts, ideas, and feelings of the conscious activity. The imaginative vision, an unconscious activity, shines through the land of chaos, of lights and shadows, silently seeking pattern and form. Finally, the conscious mind again, through Will, captures and embodies the idea in the final work of art. In this way is unity born out of chaos. Though there can be no absolute certainty, there is general agreement that the periods in the development of a creative work parallel, to some extent, Lowes" theory of Well, Vision, Form, and Will. There are at least three stages in the creative process: preparation, inspiration, work. In a sense, the period of preparation is all of the writer"s life. It is the Deep Well. It is especially a period of concentration which gives the unconscious mind an opportunity to communicate with the conscious mind. When remembrances of things past reach the conscious level of the writer"s mind, he is ready to go on with the process. Part of this preparation involves learning a medium — learning a language, learning how to write, learning literary forms. It is important to mot here that form cannot be imposed upon the idea. Evidence, though sparse, shows that the idea gives birth to the form that can best convey it. It is the Vision, according to Lowes, which sees shining in and through the chaws of the potential lines of Form..."

单选题 A recurring criticism of the U. K.'s university sector is its perceived weakness in translating new knowledge into new products and services. Recently, the U. K. National Stem Cell Network warned the U. K. could lose its place among the world leaders in stem cell research unless adequate funding and legislation could be assured. We should take this concern seriously as universities are key in the national innovation system. However, we do have to challenge the unthinking complaint that the sector does not do enough in taking ideas to market. The most recent comparative data on the performance of universities and research institutions in Australia, Canada, U. S.A. and U.K. shows that, from a relatively weak starting position, the U. K. now leads on many indicators of commercialisation activity. When viewed at the national level, the policy interventions of the past decade have helped transform the performance of U. K. universities. Evidence suggests the U. K.'s position is much stronger than in the recent past and is still showing improvement. But national data masks the very large variation in the performance of individual universities. The evidence shows that a large number of universities have fallen off the back of the pack, a few perform strongly and the rest chase the leaders. This type of uneven distribution is not peculiar to the U. K. and is mirrored across other economies. In the U. K., research is concentrated: less than 25% of universities receive 75% of the research funding. These same universities are also the institutions producing the greatest share of PhD graduates, science citations, patents and license income. The effect of policies generating long-term resource concentration has also created a distinctive set of universities which are research-led and commercially active. It seems clear that the concentration of research and commercialisation work creates differences between universities. The core objective for universities which are research-led must be to maximise the impact of their research efforts. These universities should be generating the widest range of social, economic and environmental benefits. In return for the scale of investment, they should share their expertise in order to build greater confidence in the sector. Part of the economic recovery of the U.K. will be driven by the next generation of research commercialisation spilling out of our universities. There are three dozen universities in the U. K. which are actively engaged in advanced research training and commercialisation work. If there was a greater coordination of technology transfer offices within regions and a simultaneous investment in the scale and functions of our graduate schools, universities could, and should, play a key role in positioning the U. K. for the next growth cycle.
