单选题Scientists Develop Ways of Detecting Heart Attack German researchers have (1) a new generation of defibrillators and early-warning software aimed at offering heart patients greater protection (2) sudden death from cardiac arrest. In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases (3) by disruption to the heart's rhythm. Those most at risk are patients who have (4) suffered a heart attack, and for years the use of defibrillators has proved useful in diagnosing (5) disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices (6) a range of functions, such as that of pacemaker. Heart specialists at Freiburg's University Clinic have now achieved a breakthrough with an implanted defibrillator (7) of generating a six-channel electrocardiogram (ECG) within the body. This integrated system allows early diagnosis of (8) blood-flow problems and a pending heart attack. It will be implanted in patients for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautem have developed new computer software that renders the evaluation of ECG data (9) . The overwhelming (10) of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs. "Many of the current programs only (11) into account a linear correlation of the data. We are, however, making use (12) a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system, " Hagen Knaf says, " (13) changes in the heart beats over time can be monitored and individual variations in patients taken into account. " An old study of ECG data, based (14) 600 patients who had suffered a subsequent heart attack, enabled the researchers to compare risks and to show (15) the new software evaluates the data considerably better.

单选题{{B}}第三篇{{/B}} Life at Aichi University I'm Yamamoto Mika, a 22-Year-old Japanese girl. I'd like to invite you to Aichi University so you can understand my life. Our university has a close relationship with China and my department is the only one of its kind in Japan. My courses include the Chinese language, modern Chinese politics and economics. I love the Chinese culture and I have been to Tianjin as an exchange students. In Japan, our courses are divided into compulsory(必修的), optional (选修的) and specialized(专修的) courses. However, we have a flexible schedule. We can choose classes from a wide range of options. Many students finish the compulsory courses in three years so that they can have one year with out any classes. They often use this period of time to study abroad, conduct research and travel. Many students even suspend their study for additional study-abroad opportunities. Japanese universities encourage students to choose their own ways of study, so it is quite easy for us to apply for study suspension. Japanese students participate in various kinds of extracurricular (课外的) activities. They at tend clubs from elementary schools, so many have already been accustomed to clubs when they enter university. Our university now has 42 art clubs and 45 sports clubs. The annual University Festival is the grandest carnival (狂欢节) of Japanese universities. In the festival, students promote their clubs and organize various activities. Our university's festival attracted about 150,000 people last year. I really like this festival. In school, I participate in the journalism club. When we have the club promotion, we cook "tonnjiru", a kind of pork soup, and sell it to other students at the fair. We also go to different places to interview celebrities (名人) who attend our festival as guests. It is a wonderful experience to talk to those stars face to face. Japanese students like to hold parties. We have two kinds of parties. One is the Mochiyori party. If you want to attend this party you have to cook a course and take it to the party. The organizer buys drinks and snacks. Another kind of party is the Nomikai, which mainly involves alcohol. We drink something called chu-hai, which is a combination of soda and wine. We also drink Japanese sake (清酒) and beer. There are parties for many occasions, like welcoming new students, graduation, celebrating victories, birthday parties or just for promoting friendship.

单选题In the aspect of health behavior, the concept of personal choice is very important. According to estimation, around 90 percent of all illnesses may be preventable if individuals would make sound personal health choices on a basis of current medical knowledge. We all enjoy our freedom of choice and do like restrictions when it is in the scope of legal and moral boundaries. The structure of American society allows us to make almost all our own personal decisions that may relate to our health. If we are very eager, we can smoke, drink excessively, refuse to wear seat belts, eat as we like, and live a completely sedentary life--style without any exercise. The freedom of making such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices related to health often results in a difficulty. For example, a teenager may know the facts concerned smoking cigarettes and health but may be pressured by friends into being believing to do it is socially accepted. A great many factors, both inherited and environmental, have influence on the development of health--related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. The decision to adopt a particular health, related behavior is, however, usually one of personal choices. There are healthy choices and there are unhealthy choices. When Fries and Crapo were discussing the morals of personal choice, they made a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide. Therefore, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors connecting with a statistical probability of increased vitality and longevity.

单选题Diseases of Agricultural Plants Plants, like animals, are subject to diseases of various kinds. It has been estimated that some 30,000 different diseases attack our economic plants; forty are known to attack corn, and about as many attack wheat. The results of unchecked plant disease are all too obvious in countries which have marginal food supplies. The problem will soon be more widespread as the population of the world increases at its frightening rate. Even in countries which are now amply fed by their agricultural products there could soon be critical food shortages. It is easy to imagine the consequences of some disastrous attack on one of the major crops; the resulting famines could kill millions of people, and the resulting hardship on other millions could cause political upheavals disastrous to the order of the world. Some plants have relative immunity to a great many diseases, while others have a susceptibility to them. The tolerance of a particular plant changes as the growing conditions change. A blight may be but a local infection easily controlled; on the other hand it can attack particular plants in a whole region or nation. An example is the blight which killed virtually every chestnut tree in North America. Another is the famous potato blight in Ireland in the last century. As a result of that, it was estimated that one million people died of starvation and related ailments. Plant pathologists have made remarkable strides in identifying the pathogens of the various diseases. Bacteria may invade a plant through an infestation of insect parasites carrying the pathogen. A plant can also be inoculated by man. Other diseases might be caused by fungus which attacks the plant in the form of a mold or smut or rust. Frequently such a primary infection will weaken the plant so that a secondary infection may result from its lack of tolerance. The symptoms shown may cause an error in diagnosis, so that treatment may be directed toward bacteria which could be the result of a susceptibility caused by a primary virus infection.

单选题Migrant Workers In the past twenty years, there has been an increasing tendency for workers to move from one country to another. (51) some newly independent countries have understandably restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, (52) increased oil incomes have enabled many countries to (53) outsiders to improve local facilities. (54) the Middle East has attracted oil-workers from the USA and Europe. It has brought in construction workers and technicians from many countries, (55) South Korea and Japan. In view of the difficult living and working conditions in the Middle East, it is not (56) that the pay is high to attract suitable workers. Many engineers and technicians can earn at least (57) money in the Middle East as they can in their own country, and this is a major attraction. An allied benefit is the low taxation or complete lack of it. This increases the net amount of pay received by visiting workers and is very popular with them. Sometimes a disadvantage has a compensating advantage. (58) , the difficult living conditions often lead to increased friendship when workers have to depend on each other (59) safety and comfort. (60) , many migrant workers can save large sums of money partly (61) the lack of entertainment facilities. The work is often complex and full of problems but this merely presents greater challenge to engineers who prefer to find solutions (62) problems rather than do routine work in their home country. One major problem which (63) migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. (64) , migrant workers accept this disadvantage, along with others, because of the (65) financial benefits which they receive.
