1、Will We Take Vacation in Spaces?When Mike Kelly first setout to build his own private space-ferry service, he figured his bread-and-butter business would be lofting (发射) satellites into high-Earth orbit. Now he thinks he may have figured wrong. "People were always asking me when they could go," says Kelly, who runs Kelly Space & Technology out of San Bemardino, California. "I realized that real market is in space tourism."According to preliminary market surveys, there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington, Virginia, has taken more than 130 deposits fora two-hour, $98, 000 space tour tentatively and somewhat dubiously (可疑地) setto actorby 2005. Gene Meyers of the space Island Group says: "Space is the next exotic(风光奇特的) vacation spot. "This may all sound great, but there are a few hurdles (困难). Putting a simple satellite into orbit with no oxygen, life support orreturn trip necessary already costs an astronomical (天文数字) $ 22,OOO/kg. and that doesn\'t include the oust of insuring rich and possibly litigious passenger. John Pike of the Federation of American Scientists acerbically (尖刻地) suggests that the entiregroupof entrepreneurs trying to corner (垄断) the space-tourism market have between them "just enough money to blow up one rocket."The U. S. space agency has plenty of money but zero interest in mailing space less expensive forthe little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that is inexpensive, safe and reliable. Kelly Space\'s prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in Redwood City, California, has a booster with rotors to make a helicopter-style return to Earth; Kistler Aero-space in Kirkland, Washington, is piecing together its versions from old Soviet engines, shuttle-style thermal protection tiles and an elaborate parachute system. The first passenger countdowns are still years away, but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all, you can\'t be too prepared, fora trip to that galaxy far, far away. Forthose who are intent on joining the 100-mile high club, Hilton and Budget are plotting to build space hotels. Before the Russian spaceship Mir came down, some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space, and if you are thinking of staying in it, you may want to check the Michelin ratings before booking yourself a suite. Kelly hoped to develop space tourism, which he thought would be a good market. 【单选题】
A.Right
B.Wrong
C.Notmentioned
正确答案:A
答案解析:选A的依据是第1段最后一句话,这句话表明Kelly认识到真正的市场是太空旅行,作为一个商人,他理所当然会致力于开发真正的市场。
2、Medicine Award Kicks off Nobel Prize AnnouncementsTwo scientists who have won praise forresearch into the growth of cancer cells could be candidates forthe Nobel Prize in medicine when the 2008 winners are presented on Monday, kicking off six days of Nobel announcements. Australian-born U. S. citizen Elizabeth Blackburn and American Carol Greider have already won a series of medical honors fortheir enzyme research and experts say they could be among the front-runners fora Nobel. Only seven women have won the medicine prize since the first Nobel Prizes were handed out in 1901. The last female winner was U. S. researcher Linda Buck in 2004, who shared the prize with Richard Axel. Among the pair\'s possible rivals are Frenchman Pierre Chambon and Americans Ronald Evans and Elwood Jensen, who opened up the field of studying proteins called nuclear hormone receptors. As usual, the award committee is giving no hints about who is in the running before presenting its decision in a news conference at Stockholm\'s Karolinska Institute. Alfred Nobel, the Swede who invented dynamite, established the prizes in his will in the categories of medicine, physics, chemistry, literature and peace. The economics prize is technically not a Nobel but a 1968 creation of Sweden\'s central bank. Nobel left few instructions on how to select-winners, but medicine winners are typically awarded fora specific breakthrough rather than a body of research. Hans Jornvall, secretary of the medicine prize committee, said the 10 million kronor(US$1. 3 million) prize encourages groundbreaking research but he did not think winning it was the primary goal forscientists. "Individual researchers probably don\'t look at themselves as potential Nobel Prize winners when they\'re at work," Jornvall told The Associated Press. "They get their kicks from their research and their interest in how life functions. "In 2006, Blackburn, of the University of California, "San Francisco, and Greider, of Johns Hopkins University in Baltimore, shared the Lasker prize forbasic medical research with Jack Szostak of Harvard Medical School. Their work setthe stage forresearch suggesting that cancer cells use telomerase to sustain their uncontrolled growthThe research by Blackburn and Greider helps suggest the role of____. 【单选题】
A.money in medical research.
B.proteins in cancer treatment.
C.hormones in the functioning of life.
D.telomerase in the growth of cancer cells.
正确答案:D
答案解析:短文的最后一句话表明,研究显示癌细胞利用端粒酶来支持其无限增殖,而这几位科学家的工作为这种研究打下了基础。
3、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack orstroke later in life and could prevent hundreds of thousands of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections and allergies and are less prone to obesity. British scientists have now shown that breastfeeding and slow growth in the first weeks and months of life has a protective effect against cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in terms of raising their blood pressure, raising their cholesterol and increasing their tendency to diabetes and obesity-the four main risk factors forstroke and heart attack." said ProfessorAlan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breast-fed babies do better is because they grow more slowly in the early weeks."Lucas said the effects of breastfeeding on blood pressure and cholesterol later in life are greater than anything adults can do to control the risk factors forcardiovascular disease, other than taking drugs. An estimated 17 million people die of cardiovascular disease, particularly heart attack and strokes, each year, according to the World Health Organization. Lucas and his colleagues compared the health of 216 teenagers who as babies had either been breastfed orgiven different nutritional baby formulas\' They reported their findings in The Lancet medical journal. The teenagers who had been breastfed had a 14 percent lower ratio of bad to good cholesterol and lower concentrations of a protein that is a marker forcardiovascular disease risk. The researchers also found that ______ of the child\'s weight at birth, the faster the infants grew in the early weeks and months of life, the greater was their later risk of heart disease and stroke. The effect was the same forboth boys and girls. "The more human milk you have in the newborn period, the lower your cholesterol level is, the lower your blood pressure is 16 years later, "Lucas said. 【单选题】
