共用题干第二篇The Mir Space StationThe Russian Mir Space Station,which came down in 2001 at last after 15 years of pioneering the concept of long-term human space flight,is remembered for its accomplishments in the human space flight history.It can be credited with many firsts in space.During Mir's lifetime,Russia spent about US $4.2 billion to build and maintain the station.The Soviet Union launched Mir,which was designed to last from three to five years,on February 20, 1986,and housed 104 astronauts over 12 years and seven months,most of whom were not Russian.In fact, it became the first international space station by playing host to 162 people from 1 1 countries.From 1995 through 1998,seven astronauts from the United States took turns living on Mir for up to six months each.They were among the 37 Americans who visited the station during nine stopovers by space shuttles.The more than 400 million the United States provided Russian for the visits not only kept Mir operating,but also gave the Americans and their partners in the international station project valuable experience in long-term flight and multinational operations.A debate continues over Mir's contributions to science.During its existence,Mir was the laboratory for 23,000 experiments and carried scientific equipment,estimated to be worth $80 million,from many nations.Experiments on Mir are credited with a range of findings,from the first solid measurement of the ration of heavy helium（氦）atoms in space to how to grow wheat in space.But for those favouring human space exploration,Mir showed that people could live and work in space long enough for a trip to Mars.The longest single stay in space is the 437.7 days that Russian astronaut Valery Polyakov spent on Mir from 1994 to 1995.And Sergie Avdeyev accumulated 747.6 days in space in three trips to the space station.The longest American stay was that of Shannon Lucid,who spent 188 days aboard Mir in 1996.Despite the many firsts Mir accomplished,1997 was a bad year out of 15 for Mir.In 1997,an oxygen generator caught fire.Later,the main computer system broke down,causing the station to drift several times and there were power failures.Most of these problems were repaired,with American help and suppliers,but Mir's reputation as a space station was ruined.Mir's setbacks are nothing,though,when we compare them with its accomplishments.Mir was a tremendous success,which will be remembered as a milestone in space exploration and the space station that showed long-term human habitation in space was possible.But it's time to move on to the next generation.The International Space Station being built will be better,but it owes a great debt to Mir.What happened to Mir in 1997?A:It ran out of its fund.B:Its main computer system broke down.C:It was completely damaged by fire.D:Its reputation was ruined due to power failures.

共用题干Motion SicknessLiving in space looks like lots of fun.You can do certain things in space(like floating around,or pushing huge objects)that you cannot do on earth.But being in space can do things to you,too.If you stay too long in a gravity-free environment,your bones could become weak,and a small spaceship just might annoy you after a while,because space travel could make you seasick!On July 4, 1982,after seven days orbiting the earth,astronauts Thomas K. Mattingly and Henry W. Hartsfield returned home.Although not all of the experiments on board worked properly,the flight basically seemed to be a success except for one"little"thing: early in the flight,astronaut Hartsfield became"seasick".Thomas Mattingly,who is also a jet pilot and is highly resistant to motion sickness on earth,did much better.Mattingly sailed through space with a steady stomach.But no one knows why Hartsfield felt uneasy and Mattingly did not.So far it seems there is no reliable way to predict who will become motion sick in outer space and who will not.In all,at least four astronauts have suffered from space motion sickness. Russian and American scientists are working together to try to understand and solve the motion sickness.Space program officials worry that if so many highly-trained pilots get sick in space,what will happen when civilians start flying in the shuttle?Motion sickness is a disagreeable feeling that comes from the pitching,rolling, swaying,or just the moving of the object you are riding in or on.Symptoms of motion sickness include:dizziness,headache,a sinking feeling in the stomach,and vomiting （呕吐）.Why does motion make some people ill?Doctors believe that motion sickness is caused by a disturbance in the inner ear.Our ears do more than give us hearing.A part of the ears gives us a sense of balance and helps make us aware of whether we are right side up or upside down.If you know that you get carsick or seasick,what can you do?Speak to your doctor.

共用题干Will We Take Vacation in Spaces?When Mike Kelly first set out to build his own private space-ferry service,he figured his bread-and-butter business would be lofting 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 runsKelly Space TechnologT out of San Bernardino,Californi a.“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 1 30 deposits for a two-hour,$98,000 space tour tentatively(and somewhat dubiously)set to occur by 2005 .Gene Meyers of the Space Island Group says:“Space is the next exotic vacation spot.”This may all sound great,but there are a few hurdles.Putting a simple satellite into orbit with no oxygen,life support or return trip necessary already costs an astronomical $22,000/kg.And that doesn't include the cost of insuring rich and possibly litigious passenger. John Pike of theFederation of American Scientists acerbically suggests that the entire group of entrepreneurs trying to corner 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 making space less expensive for the little guys.So the little guys are racing to do what the government has failed to do:design a reusable launch system that's inexpensive,safe and reliable.Kelly Space's prototype looks like a plane that has sprouted rocket engines.Rotary Rocket in Redwood City,California,hasa booster with rotors make a helicopter-style return to Earth;Kistler Aerospace in Kirkland,Wash- ington,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 for a trip to that galaxy far,far away.For those who are intent on joining the 100-mile high club,Hilton and Budget are plotting to build space hotels.Before the Russian space 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're thinking of staying in it,you may want to check the Michelin ratings before booking yourself a suite. It sounds great that soon there will be space residence,although it is still a tentative plan.A: RightB: WrongC: Not mentioned

共用题干第三篇Human Space ExplorationWhile scientists are searching the cause of the Columbia disaster,NASA is moving ahead with plans to develop a new craft that would replace shuttles（航天飞机）on space station missions by 2012 and respond quickly to space station emergencies.The space agency released the first set of mission needs and requirements several days ago for the orbital space plane（轨道航天飞机）,which would be designed to transport a crew of four to and from the International Space Station.Although it includes few specifics, the plan states the orbiter（轨道航天飞机）will be safer,cheaper and require less preparation time than the shuttle.It would be able to transport four crew members by 2012一though it would be available for rescue missions by 2010.NASA says the craft should be able to transport injured or ill space station crew members to "definitive（决定性的）medical care" within 24 hours.The release of the requirements showed NASA remains focused on the long-term priorities of space exploration,even as questions exist concerning the loss of Columbia and its seven-member crew on February 1,2003.Experts at Marshall Space Flight Center in Huntsville,Alabama,have been working for years on a successor to the shuttle.The project,known as the Space Launch Initiative（倡议）,was divided last year into two parts一one focusing on a future launch vehicle,the other on a space station orbiter. The orbiter is expected to be ready sooner.The program's managers say NASA officials have told them not to alter Space Launch Initiative in light of the Columbia disaster.U.S. President George W. Bush asked Congress for about U.S.$1 billion for Space Launch Initiative in 2004,funds that would be almost equally split between the Orbital Space Plane and Next Generation Launch Technology.NASA plans to design the new space craft toA:control the International Space Station.B:carry astronauts to the International Space Station.C:transport equipment to the International Space Station.D:train astronauts in space flights.

问答题Read the passage carefully and answer questions 1 to 5. Answer each question in a maximum of 10 words. Remember to write the answers on the answer sheet Would you like to orbit the Earth inside the International Space Station? Now you can take a space holiday—for a price. This is due to a recent decision by top space officials of the United States, Russia, Canada, Japan and the European Space Agency. Last April, American businessman Dennis Tito reportedly paid between twelve-million and twenty-million dollars to spend one week on the International Space Station. NASA had strongly objected to the Russian plan to permit a civilian on the costly research vehicle. After two years of negotiations, space officials have agreed on a process to train private citizens to take trips to the International Space Station. NASA recently agreed to conditions that will permit Russia to sell trips to the space station. The trips are planned by an American company called Space Adventures Limited of Arlington, Virginia. The company calls itself “the world’s leading space tourism company.” The company has sold a space trip to Mark Shuttleworth, a South African businessman. In April, Mister Shuttleworth will be launched into space from the Baikonur Cosmodrome in Kazakhstan. Yet, the average citizen will not be able to travel into space in the near future. Space Adventures Limited sells a training program for space flight that costs two-hundred-thousand dollars. That price does not include the cost of the trip to the International Space Station. That holiday in space costs twenty-million dollars. Candidates for adventure space travel trips must be in excellent health and must pass difficult health tests. They must receive a lot of training and all successful candidates who wish to travel to the International Space Station must be able to read and speak English. Questions: 1．How much did American businessman Dennis Tito pay to spend one week on the International Space Station? 2．Why Mark Shuttleworth, a South African businessman, is mentioned in the passage? 3．What was NASA’s original attitude towards the Russian plan to permit a civilian on the International Space Station? 4．How much should one pay for a trip to the International Space Station? 5．According to the last paragraph, what conditions must a candidate of space travel meet?

问答题Practice 4 The furthest we have been is the Moon. If we want to travel into deep space, beyond our own backyard, the Solar System, we’ll need a new breed of spacecraft. It may be the oldest clich6 in town, but in the not too distant future science fiction will turn into science fact. The fantastic spaceships of sci-fi comic books and novels will no longer be a figment of our creative imagination; they may be the real vision of our future. Engineers and designers are already designing craft capable of propelling us beyond Earth’s orbit, the Moon and the planets. They’re designing interstellar spaceships capable of travel across the vast emptiness of deep space to distant stars and new planets in our unending quest to conquer and discover. Our Universe contains over a billion galaxies; star cities each with a hundred billion inhabitants. Around these stars must exist planets and perhaps life. The temptation to explore these new realms is too great. First things first-we’ll have to build either a giant orbiting launch platform, far bigger than the International Space Station (ISS), or a permanently manned lunar base to provide a springboard for the stars. Some planners feel we should limit ourselves to robotic probes, but others are firmly committed to sending humans. “There’s a debate right now about how to explore space,” says astronaut Bill Shepherd, destined to be the first five-aboard Commander of the ISS. “Humans or machines-I think they’re complementary.” The Human Problem Space is the most hostile environment we will ever explore. Even a single five-hour spacewalk requires months of training, and a vast technical backup to keep it safe. The astronauts and cosmonauts who live aboard the ISS will be there for only a few weeks or months; if we want to travel into deep space it could take years. First we’ll have to find out just how long the human body can survive in a weightless environment. In zero gravity, four pints of body fluid rush from the legs to the head where it stays for the duration of the mission. Astronauts often feel as if they have a permanent cold, and disorientation can become a major problem. In space there’s no physical sensation to let you know when you’re upside down and astronauts have to rely on visual clues from their surroundings. A few hours after reaching orbit, one in three of all astronauts will experience space sickness-a feeling rather like carsickness. And weightless conditions lead to calcium being leached from the bones, and problems with the astronauts’ immune systems. Trillions of rocky fragments-meteoroids-roam our Solar System at speeds of up to150, 000 miles an hour. A meteoroid no bigger than a grain of salt could pierce a spaceship window. Protection from the extreme hazards of space is going to need some clever technology. Space is also full of lethal radiation-X-rays, gamma rays and the high-speed particles called cosmic rays.
