单选题{{B}}第三篇{{/B}} {{B}} Controlling the Growing TB Crisis in China{{/B}} China needs to take urgent action to address a "vicious cycle" of poverty and tuberculosis (TB) affecting a considerable number of Chinese people, especially in underdeveloped areas, the World Health Organization said on Monday. The Chinese government needs to take "immediate necessary action" to control the spread of TB, which is "threatening the future of its 1.3 billion people", WHO said in a report released at the start of a three-day meeting to discuss TB in the Western Pacific region. Poor living conditions and health care in rural China mean the TB infection rate is nearly three times higher than in urban areas, the report said. There are some factors that make the rural TB burden heavier such as insufficient funds for local health programs and increased charges for medical care, it said. "This has uniformly produced a negative impact on TB diagnosis and treatment, especially in areas without specific funding targeted towards TB-related services," it said. The report, which is meant to foreshadow the seriousness of the TB crisis in China, suggests that China adopt a two-year program to control the disease. The government should fund free TB drugs and diagnosis, health promotion and training, and supervised treatment programs at all levels, it said. "TB control should be considered as a key development issue and poverty reduction strategy," WHO Western Pacific regional director Dr. Shigeru Omi said at the opening of the meeting in Beijing. A World Bank-funded project in 13 of China's 31 provinces produced "astonishing" results, reducing the incidence of TB by 38 per cent in less than 10 years, WHO said. "This tremendous achievement tells us that the regional target of reducing the prevalence of TB by half in 10 years, though ambitious, is achievable," Omi said. But TB "remains a relentless killer in the Western Pacific region", claiming around 1,000 lives daily in the region -- more than half of them in China, a WHO press statement said. "The worsening burden of TB has resulted in a great human tragedy and has had a profound impact on economic development in several countries in the region," the statement said.

单选题A New Cause of Suffering A conference on obesity (肥胖症) was recently held in Vienna. Two thousand experts from more than fifty countries attended the conference. According to statistics, 1.2 billion people worldwide are overweight, and 250 million are too fat. Obesity is rapidly becoming a new cause of suffering. Professor Friedrich Hopichler of Salzberg said: "We are living in the new age but with the metabolism (新陈代谢) of a stone-age man. I have just been to the United States. It is really terrible. A pizza (比萨饼) shop is appearing on every corner. We have been occupied by fast food and Coca-Cola-ization. " Many of the experts stressed that obesity was a potential killer. Hopichler said: "Eighty percent of all diabetics (糖尿病人) are too fat, also fifty percent of all patients with high blood pressure and fifty percent with fatty tissue complaints. Ten percent more weight means thirteen percent more risk of heart disease. Reducing one"s weight by ten percent leads to thirteen percent lower blood pressure. " Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs. "The health insurance pays for surgery (such as reducing the size of the stomach) when the body-mass index (身体质量指数) is more than 40. That is equivalent to a weight of 116 kilograms for a height of 1.60 meters. One should start earlier. " Toplak said that prevention should begin in school. "Child obesity has a close relation with the time which children spend in front of TV sets. "

Our skins let us know whether the air is moist or dry, whether surfaces are wet without being sticky or slippery. From the uniformity of slight pressure, we can be aware how deeply a finger is thrust into water at body temperature, even if the finger is enclosed in a rubber glove that keeps the skin completely dry. Many other animals, with highly sensitive skins, appear to be able to learn still more about their environment. Often they do so without employing any of the five senses. By observing the capabilities of other members of the animal kingdom, we come to realize that a human being has far more possibilities than are utilized. We neglect ever so many of our senses in concentrating on the five major ones. At the same time, a comparison between animals and man draws attention to the limitations of each sense. The part of the spectrum(光谱)seen by color-conscious man as red is non-existent for honey-bees. But a bee can see far more in flowers than we, because the ultra-violet(紫外线)to which our eyes are blind is a stimulating(刺激的)part of the insect's spectrum, and, for honeybees at least, constitutes a separate color.

单选题Lack of Sleep Increases the Risk of Catching a Cold As cold season approaches, many Americans stock up on their vitamin C and Echinacea (紫锥花精油). But fallowing the age -old advice about catching up on sleep might be more important. Studies have demonstrated that poor sleep and susceptibility (易受影响) to colds go hand in hand, and scientists think it could be a reflection of the role sleep plays in maintaining the body's defenses. In a recent study for the Archives of Internal Medicine, scientists followed 153 men and women for two weeks, keeping mack of their quality and duration of sleep. Then, during a five - day period, they quarantined (进行检疫隔离) the subjects and exposed them to cold viruses. Those who slept an average of fewer than seven hours a night, it turned out, were three times as likely to get sick as those who averaged at least eight hours. Sleep and immunity, it seems, are tightly linked. Studies have found that mammals that require the most sleep also produce greater levels of disease - fighting white blood cells--but not red blood cells, even though both are produced in bone marrow (骨髓) and stem from the same precursor (前体物). And researchers at the Max Planck Institute for Evolutionary Anthropology have shown that species that sleep more have greater resistance against pathogens (病原体). "Species that have evolved longer sleep durations," the Planck scientists wrote, "appear to be able to increase investment in their immune systems and be better protected. /

Some people are worded that anthrax may be connected to terrorist attacks or that terrorists may spread the germ that{{U}} (1) {{/U}}the disease. Federal officials and police are investigating this and taking measures to protect us. In the meantime, it's important not to panic over anthrax. The chances that you and your family{{U}} (2) {{/U}}at risk are very tiny. One of the ways you can feel better is to learn about anthrax. When you know what it is and{{U}} (3) {{/U}}you can get it, it doesn't seem quite as scary. So, what{{U}} (4) {{/U}}is anthrax? Here are the facts on anthrax: Anthrax is a bacterial infection caused by a germ. Although it's most common in farm{{U}} (5) {{/U}}, like sheep, cows, pigs, horses, and goats, there's a very small chance that people can get it, too. Anthrax spores (a version of the germ in a protective shell that can live in the soil for years) cause the disease. People may get anthrax if they are exposed to anthrax{{U}} (6) {{/U}}. But here's the important part: just being exposed to these spores doesn't mean that a person will get{{U}} (7) {{/U}}. For people to get sick, they would have to breathe in thousands of these spores all the way into their{{U}} (8) {{/U}}. Or they'd have to eat meat contaminated with anthrax or handle{{U}} (9) {{/U}}that has anthrax spores. This may sound scary, but even when people come{{U}} (10) {{/U}}contact with the spores, it's unlikely that they'll get sick.{{U}} (11) {{/U}}the bacteria do not get into the skin, digestive tract, or lung, the disease won't develop. Anthrax is not spread from person to person the way the flu can spread from family member to{{U}} (12) {{/U}}member or classmate to classmate. Anthrax is very rare. Until recently, anthrax wasn't even talked about because it was so rare-- and it still{{U}} (13) {{/U}}! Even with all of the anthrax cases you are hearing about right now(and many of these suspected cases will turn out not to be anthrax), a person's chances of getting anthrax are about the{{U}} (14) {{/U}}as they were before you heard about anthrax on the news -- very, very low. If you still feel scared when you hear about anthrax, remember that it's extremely unlikely thatyou or your family or anyone you know will ever be{{U}} (15) {{/U}}to anthrax spores.

单选题Excessive Demands on Young People Being able to multitask is hailed by most people as a welcome skill, but not according to a recent study which claims that young people between the ages of eight and eighteen of the so-called Generation M are spending a considerable amount of their time in fruitless efforts as they multitask. It argues that, in fact, these young people are frittering away as much as half of their time again as they would if they performed the very same tasks one after the other. Some young people are juggling an ever larger number of electronic devices as they study. At the same time that they are working, young adults are also surfing on the Internet, or sending out emails to their friends, and/or answering the telephone and listening to music on their iPods or on another computer. As some new device comes along it too is added to the list rather than replacing one of the existing devices. Other research has indicated that this multitasking is even affecting the way families themselves function as young people are too wrapped up in their own isolated worlds to interact with the other people around them. They can no longer greet family members when they enter the house nor can they eat at the family table. All this electronic wizardry is supposedly also seriously affecting young people's performance at university and in the workplace. When asked about their perception of the impact of modern gadgets on their performance of tasks, the overwhelming majority of young people gave a favorable response. The response from the academic and business worlds was not quite as positive. The former feel that multitasking with electronic gadgets by children affects later development of study skills, resulting in a decline in the quality of writing, for example, because of the lack of concentration on task completion. They feel that many undergraduates now urgently need remedial help with study skills. Similarly, employers feel that young people entering the workforce need to be taught all over again, as they have become deskilled. While all this may be true, it must be borne in mind that more and more is expected of young people nowadays; in fact, too much. Praise rather than criticism is due in respect of the way today's youth are able to cope despite what the older generation throw at them.
