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.

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.

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.When did NASA start working on a successor to the shuttle?A:One year before the Columbia disaster.B:One year after the Columbia disaster.C:Immediately after the Columbia disaster.D:Years before the Columbia disaster.

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Is There Life on Mars? The American space agency, NASA (the National Aeronautics and Space Administration), has drawn up a short list of ten research projects that will form the basic of an ambitious program to explore the planet Mars in a mission scheduled for launch in 2007. Scientists are being asked to use their ingenuity to devise novel ways to explore the red planet using intelligent robots and probes that might perhaps answer the biggest question of all—-is there life on Mars? NASA chose the ten projects from a list of 43 hopefuls. It has included missions for returning samples of Martian dust and gas to Earth, networks of small landers, orbiting constellations of microprobes and a rover that would try to date the precise age of rocks and soils. The ten concepts are part of the Mars Scout program to be launched in six years. This follows a decade of the most intensive interest in Mars since the two Viking probes of 1976 which sent back eerie images of the Martian landscape some 400 million kilometers away. But the history of Mars exploration is littered with failure—more than half of the 30 missions to date have ended in fiasco. It was NASA’s announcement in August 1996 of possible signs of life in a Martian meteorite which had fallen to Earth that rekindled intense interest in Earth’s nearest neighbor. It was assumed that liquid water had once flowed on Mars and an ancient atmosphere might have supported living organisms. However, opposing camps of scientists bitterly disputed NASA’s evidence for primitive life-forms in the Martian meteorite ALH84001. This led to the conclusion that the only way of finding out whether life ever existed on Mars is to go there and have a look. NASA planned a bold series of increasingly complex missions involving the launch of a couple of space probes every year for a dozen years. One of the most successful so far was the shoe-box-sized So-journer rover which thrilled a world Internet audience when it was wheeled out in 1997. Since then, however, NASA has suffered a series of setbacks. In September 1999 its Mars Climate Orbiter was lost as a failed rocket bum plunged it into the Martian atmosphere. NASA blamed it on one of its team using imperial units and another using metric. Three months later, NASA lost contact with its Polar Lander as it approached touchdown on the frozen South Pole of the planet. Space commentators muttered darkly about Mars being a cosmic equivalent of the Bermuda triangle. The year of 2001 saw the successful completion of the Global Surveyor mission, an orbiting probe that took pictures of what some scientists say are channels in the dust where water may still occasionally flow from underground well. More recently, the Mars Odyssey probe was launched without hitch and is due to arrive in 2008. Meanwhile, the European Space Agency is planning its own visit to the red planet with the launch of its Mars Express mission scheduled for take-off in .June 2003. Britain is designated to take a lead role in the project with the Beagle 2 Lander, a small craft, the size of a kitchen sink designed to shuffle over the Martian landscape taking soil and rock samples, analyzing them for signs of life and transmitting the data back to Earth. Beagle 2—framed after the ship that carded Charles Darwin on his voyage of discovery—will weigh just 60 kilograms and will cost about US $225,000 to build, a fraction of the cost of building the Viking space probes more than 25 years ago. Beagle 2 will look for water, minerals and organic matter. Although it will reach Mars before NASA’s Scout mission is even launched, it will be considerably less sophisticated in tea’ms of analytical technology. The focus now for NASA is on what instruments and robots to put on the Mars Scout mission in six years. Ed Weiler, NASA’s associate administrator for space science, had to decide on a top ten to concentrate NASA’s limited resources. Each project is to receive a grant of $150,000 to see them through the next six months of development. It all has to come out of a total project budget capped at $300 million. These Scout concepts embody the spirit I first thought about more than a year ago; and will enable us to explore the diversity of Mars in new ways, Dr Weiler said.

问答题Passage 1 Neither the Americans nor the Russians have the resources to continue human space flight on their own; both sides know they need each other. (1) It’s much easier and cheaper to get used to each other and to blend differing operating styles, languages, and systems on the aged Mir (a Russian word for “peace”) than trying to do that while jointly building a new space station. NASA, in fact, calls its program of shuttle lights to Mir Phase 1 of the International Space Station (ISS). Phase 2 marks the beginning of actual construction. The procedures used to dock the shuttle to Mir, for example, also will be used as a lifeboat for the Island Progress freighters, like the one that crashed into Mir in June, will haul cargo to the ISS. (2) One unintended benefit of Mir’s technical troubles is that they have actually forced the two nations to work much more closely together than they had planned. Except for a brief period in the 1970s with Skylab, NASA has never operated a space station; the Russians have been running them for years. Astronauts have long been trained intensively to perform specific tasks on shuttle flights lasting 18 days or less. (3) Russian astronauts, however, learn more general skills, since they spend many months in orbit and no one can forecast all the problems they might encounter. As a result of shuttle-Mir experience, NASA is revising astronaut training to include more of the general skills they will need on the ISS. NASA decided to send astronauts to Mir based on its long record of safe operation. But this year, crews aboard Mir have faced two of the most serious emergencies in the history of human space flight. (4) In February, an oxygen generator caught fire, shooting out 4-foot-long jets of flame like; fire extinguishers were bolted in place, delaying reaction to the fire. In June, a Progress Freighter collided with the Specter module, puncturing it. Specter had to be sealed off to prevent all the air from leaking from the spacecraft. (5) The ancient computer that controls Mir has failed many times, causing most other systems, including the one that keeps the station’s solar panels pointing at the sun, to shut down. One failure in August occurred while a Progress was docking. Last week, the computer crashed again, the carbon dioxide removal system shut down, and a mysterious brown fluid — probably rocket fuel — appeared to leak from the station.
