单选题Normally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit (学分) which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester (学期). A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice. For every course that he follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.

单选题{{B}}Passage Four{{/B}} In 10 years, the mutual-fund industry won't even be called that. The term "mutual fund" will be much too confining to encompass(包括) the various types of mixed investment vehicles(手) that will be available to investors around the world. Technology, especially the Internet, will be the most significant driver, affecting every aspect of the mutual-fund industry, from products and delivery to providers and customers. The future version of today's mutual funds will be available for purchase across the globe by citizens of many nationalities in just about any currency. The average investor will be able to trade bonds as well as stocks with ease 24-hours a day, 365 days a year by using voice-held, satellitelinked PCs. A Brazilian citizen, for example, will be able to buy shares of the Vanguard 500 Index Fund in London at midnight, using its price in New York at 02:00 Greenwich Time, to be settled in Japanese yen. With the vast amount of information and instantaneous (瞬间) service available to investors through the Internet, the merits of an investment product will drive its consumption. Investment products in the next decade will come in finer shades of investment objectives. Demand for investment products will be huge around the world. In the United States, there has been considerable discussion of the impact that maturing baby boomers will have on financial markets and levels of investment. The subsequent Generation X and Internet Generation groups are very likely to pick up any slack (呆滞,萧条) due to disinvestment by boomers, and on their own, elevate investment to a new level by 2008. Generation X'ers(新生的一代人) appear to be more highly motivated to invest than the boomers, while the Net Generation' s comfort level with technology will stimulate investment as well.

单选题Motherhood may make women smarter and may help prevent dementia (痴呆) in old age by bathing the brain in protective hormones (荷尔蒙), U.S. researchers reported on Thursday. Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer"s (早老痴呆症). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans. "Our research shows that the hormones of pregnancy (怀孕) are protecting the brain, including estrogen (雌激素), which we know has many neuroprotective (保护神经的) effects," Kinsley said. "It"s rat data but humans are mammals just like these animals are mammals," he added in a telephone interview. "They go through pregnancy and hormonal changes." Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer"s and other forms of age-related brain decline. "When people think about pregnancy, they think about what happens to babies and the mother from the neck down," said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida. "They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations(改变) to the brain."

单选题(四川大学2010年试题) You probably know that it's better for both you and the environment if you buy an organic tomato instead of one that's been doused in pesticides, but there are lots of other things to consider before venturing down the aisle of your local supermarket(or farmer's market). The explosion in【1】produce and other foods during the last few years has been an extremely【2】development in the food industry. However,【3】still exists about exactly what the organic【4】means. Do you know the difference between a cereal that's "organic", 100% organic, and "made with organic【5】"? The USDA has clearly defined standards that【6】which of those labels can legally go on your raisin bran. You can learn more about them at www. usda. gov. Organic foods are great, but the jury is still very much out【7】another new development in the food world; genetically【8】organisms(GMOs). No one knows for certain the short and【9】effects of these products of gene engineering,【10】there's a chance they could lead to the【11】creation of "superweeds" or【12】with natural plant stocks. For more information on GMOs, we recommend visiting www. saynotogmos. org. 【13】you're shopping, don't forget to consider the companies behind the【14】names. One cereal company might be an environmental champion,【15】the other manufactures its corn flakes via【16】environmental practices. An easy way to compare two companies is to use【17】such as www. responsible shopper. com. They present both the good and bad sides of every company they【18】, and they grade hundreds of companies on social, ethical and environmental issues. Remember;【19】conscious shopping is a powerful tool for effecting change. You can make a difference every time you fill your【20】cart.

单选题Animal studies are under way, human trial protocols are taking shape and drug makers are on alert. All the international health community needs now is a human vaccine for the bird flu pandemic sweeping a cluster of Asian countries. The race for a vaccine began after the first human case emerged in Hong Kong in 1997. Backed by the World Health Organization (WHO), three research teams in the US and UK are trying to create a seed virus for a new vaccine. Their task is formidable, but researchers remain optimistic." There are obstacles, but most of the obstacles have been treated sensibly," says Richard Webby, a virologist at St. Jude Children's Research Hospital in Memphis, Tennessee. The biggest challenge is likely to be the rapidly mutating virus. Candidate vaccines produced last year against the H5N1 virus are ineffective against this year's strain. Scientists will have to constantly monitor the changes and try to tailor the vaccine as the virus mutates. They can't wait to see which one comes next. The urgency stems from fears that I-ISN1 will combine with a human flu virus, creating a pathogen(病原体) that could be transmitted from person to person. But if people have no immunity to the virus, the strain may not mutate as rapidly in people as it does in birds. To quickly generate the vaccine, researchers are using reverse genetics, which allows them to skip the long process of searching through reassorted viruses for the correct genetic combination. Instead, scientists clone sequences for hemagglutinin(红血球凝聚素) and neuraminidase(神经氨酸苷酶), the two key proteins in the virus. The sequences are then combined with human influenza genes to create a customized reference strain. Because products developed with reverse genetics have never been tested in humans, the candidate vaccines will first have to clear regulatory review. In anticipation, the US Food and Drug Administration (FDA) and the European Agency for the Evaluation of Medicinal Products (EMEA) are both preparing pandemic response plans. The EMEA has produced a fist-track licensing program, an industry task force and detailed guidance for potential applicants. In Europe, a reassortant influenza virus -- but not the inactivated vaccine -- produced by reverse genetics would be considered a genetically modified organism, and manufacturers would need approval from their national or local safety authorities. The WHO has prepared a preliminary biosafety risk assessment of pilot-lot vaccine, which could help speed up the review. A preliminary version of their protocol calls for several hundred subjects, beginning with a group of young adults and gradually expanding to include those most susceptible to the flu -- children and the elderly." If we had product," says Lambert," it would probably be a couple of months at the earliest before we have early data in healthy adults./
