He was the first tourist in space. “I spent sixty years on Earth and eight days in space and from my viewpoint, it was two separate lives,” Tito explained. He loved his time in space. “Being in space and looking back at earth is one of the most rewarding experiences a human being can have.”This kind of experience isnt cheap. It cost $ 20 million. However, Tito achieved his dream so he was happy. “For me it was a life dream. It was a dream that began when I didnt have any money,” he told reporters.On 30 April 2002, Mark Shuttleworth became the worlds second space tourist. Shuttleworth is a South African businessman. At the age of twenty-eight he also paid $ 20 million for the eight-day trip.Both Tito and Shuttleworth bought their tickets from a company called Space Adventures. The company has around 100 people already on their waiting list for flights into space. The spaceship to take them doesnt exist yet.Many of the customers are people who like adventure. They are the kind of people who also want to climb Mount Qomolangma. Other customers are people who love space. However, these people are worried. Because its so expensive, only very rich people can go into space. They want space travel to be available to more people. That day may soon be here. Inter Orbital Systems (IOS) plans to send up to four tourists a week into space. The tours will depart from an island in Tonga. The company promises a package that includes forty-five days of astronaut training in Russia and California, seven days in space, and a vacation in Tonga for $2 million.However, space flight is still very dangerous. Bill Readdy is NA SAs deputy assistant administrator for space flight. He says that the chances of dying are about 1 in 500. Because of this it may take time before space tourism really takes off. You might be able to go up, but will you come down?16. Dennis Tito was the first tourist in space.A. Right B. Wrong C. Not mentioned17. Mark Shuttleworth is an engineer from the United States.A.

Although these molecules allow radiation at visible wavelengths, where most of the energy of sunlight is concentrated, to pass through, they absorb s ome of the longer-wavelength infrared emissions radiated from the Earths surface, radiation that would otherwise be transmitted back into space. For the Earth to maintain a constant average temperature, such emissions from the planet must balance incoming solar radiation. If there were no carbon dioxide in the atmosphere, heat would escape from the Earth m u c h more easily. The surface temperature would be so m u c h lower that the oceans might be a solid mass of ice.2 Today, however, the potential problem is too m u c h carbon dioxide. The burning of fossil fuels and the clearing of the forests have increased atmospheric carbon dioxide by about 15 percent in the 1st hundred years, and w e continue to add carbon dioxide to the atmosphere. Could the increase in carbon dioxide cause a global rise in average temperature and could such a rise have serious consequences for h u m a n society? Mathematical models that allow us to calculate the rise in temperature as a f unction of the increase indicate that the answer is probably yes.3 Under present conditions a temperature of-18 °C can be observed at an altitude of 5 to 6 kilometers above the Earth. Below this altitude (called the radiating level), the temperature increases by about 6 ° C per kilometer approaching the Earths surface, where the average temperature is about 15 ° C. A n increase in the amount of carbon dioxide means that there are more molecules of carbon dioxide to absorb infrared radiation. A s the capacity of the atmosphere to absorb infrared radiation increase, the radiating level arid the temperature of the surface must rise.4 One mathematical model predicts that doubling the atmospheric carbon dioxide would raise the global m e a n surface temperature by 2.5 ° C. This model assumes that, the atmospheres relative humidity remains constant and the temperature decreases with altitude at a rate of 6.5 ° C per kilometer.5 The assumption of constant relative humidity is important, because water vapor in the atmosphere is another efficient absorber of radiation at infrared wavelengths. Because w a r m air can hold more moisture than cool air, the relative humidity will be constant only if the amount of water vapor in the atmosphere increases as the temperature rises. Therefore, more infrared radiation would be absorbed and reradiated back to the Earths surface. The resultant warming at the surface could be expected to melt snow and ice, reducing the Earths reflectivity. More solar radiation would then be absorbed, leading to a further increase in temperature.A The prediction of the modelB The influence on temperatureC The effect of carbon dioxideD Impact on School EducationE The import of the assumptionF The serious consequences23.Paragraph1 _ 24.paragraph3 _25.Paragraph4 _26.Paragraph5 _ 27.

Think again. Getting s ome exercise m a y help, too. N e w research with older people suggests that taking regular walks helps them pay attention better than if they didnt exercise.Previous research had shown that mice learn, remember, and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who d o n t. Their brain cells also m a k e more connections.Neuroscientists from the University at Urbana-Champaign wanted to find out if the same thing is true for people. First, they measured the physical fitness of 41 adults, ages 58 to 77，after each person walked 1 mile. Then,participants looked at arrows on a computer screen and had to use computer keys to sho w which w a y one particular arrow was pointing.Adults w h o were physically fit were faster at the arrow task, and their answers were just as accurate as their less fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisions.In a second study, 15 elderly people w h o completed a 6-month aerobic-training course were faster at attention tasks compared with 14 seniors w h o just did stretching and toning exercises for the same amount of time.So, even going for a walk every 2 or 3 days for just 10 to 45 minutes can help. That should be good news for your grandparents.The effects of exercising on the brains of younger people havent been studied yet. Still, it cant hurt to take occasional study breaks and go for a walk or run around with your friends. Y o u might even do better in school.Whatever you do, though, d o n t try to read and walk at the same time. Y o u could end up hurting yourself!2015年职称英语考试题库下载！100%压中原题： 复制到链接栏打开31.

After taking exercise for a few weeks, the mice were found to h a v e_ .A. higher blood pressureB. faster heartbeatC. more blood flow to the brainD. better appearance33. T he first study on 41 elderly people found_ .A. the less-fit participants did arrow tasks fasterB. the fitter participants did arrow tasks fasterC. the less-fit participants gave more accurate answersD. the fitter participants gave more accurate answers34. It can be good for health w h e n one takes a walk every 2 or 3 days for at least _ .A. 3 minutesB. 45 minutesC. 30 minutesD. 10 minutes35. It is suggested in the last paragraph that people shouldA.run around once a wee kB.not read and walk at the same timeC.go for a walk every dayD.not hurt their friends while exercising 第 2 篇 Night o f the L iving AntsW h e n an ant dies, other ants m o v e the dead insect out of the nest. This behavior is interesting to scientists,w h o wonder h o w ants k n o w for sure and so soon that another ant is dead.Dong - H w a n Choe, a scientist at the University of California found that Argentine ants have a chemical on the outside of their bodies that signals to other ants. “Im dead. Take m e away.” But theres a twist to C h o e s discovery. These ants are a little bit like zombies ( 僵尸）. Choe says that the living ants, not just the dead ones,
