星期3 WednesdayBetter to light one candle than to curse the darkness. 与其诅咒黑暗，不如燃起蜡烛。

Text AHalf a dozen radio stations about the face of the globe crackled sparks of electricity from capital and into millions of humble homes; peace came through the air and was simultaneous over all the face of the earth. The great ceremony on the battleship Missouri in Tokyo Bay was anticlimax.The greatest fleet in the world lay amidst the greatest ruins in the world under a dark and cheerless covering of clouds. The USS Iowa was on one side of the Missouri, the USS South Dakota on the other. A tattered flag with thirty-one stars was hung on one of the turrets of the battleship —the flag of the infant republic, which Commodore Perry brought with him to the same bay almost a hundred years before. Above the mainmast fluttered the battle flag of the Union of today. The deck was crowded with the American technicians. There were a Russian with a red band about his cap and a Tass newsreel man who insisted on crawling in among the main actors to get his shots; there was a Canadian general who spoiled his part and signed on the wrong line; there was a carefully tailored Chinese general from Chungking.Half a dozen Japanese were piped over the side of the Missouri, but for the purpose of history and in every man’s memory there were only two —the general, Umezu, and the statesman, Shingemitsu. Umezu was dressed in parade uniform, all his ribbons glistening, and his eyes blank, but you could see the brown pockmarks on his cheeks swelling and falling in emotion.Shingemitsu was dressed in a tall silk hat and a formal morning coat as if he were attending a wedding or a funeral. He had a wooden leg, and he limped along the deck; when he began to climb to the veranda deck where the peace was to be signed, he clutched the ropes and struggled up with infinite pain and discomfort.Shingemitsu and Umezu were brought forward, and, after a few carefully chosen words beautifully spoken by General MacArthur, they signed their names to a document marking an end to the Japanese Empire. When they had signed, the generals and admirals of all the other nations put their signatures to the document, and peace, if peace it was, had come.1. The document was signed on[A] the USS Iowa. [B] the USS South Dakota.[C] the battleship Missouri. [D] didn’t mention.2. In the second paragraph, “A tattered flag with thirty-one stars” is of[A] USS. [B] the infant USA.[C] today’s USA. [D] the greatest fleet.3. When portraying Umezu and Shingemitsu, the author focused on all the following EXCEPT[A] facial expression. [B] appearance.[C] motions. [D] inner activity.4. By saying “and peace, if peace it was, had come”, the author implied that[A] he valued the signature ceremony.[B] he was sure of the peace coming.[C] he suspected that the signature meant the real end of war.[D] he believed the signature ceremony would bring peace.Text BLeft unfettered(无拘无束的), Anthony Konieczka, 9 years old, would happily thumb away at his Game Boy Advance or PlayStation 2 from the minute he gets up to the moment he crawls intobed, 14 bleary-eyed(睡眼惺忪的)hours later.Anthony’s basement is stocked with traditional toys — board games, puzzles, art supplies —and as far as he is concerned, they are relics of Christmases past. His sister Michaely, 6 years old, still likes dressing her Barbies. But once she starts playing Game Boy it’s hard to get her away.Play patterns like this could grab another Christmas for the toy department. Through September, toy sales were down 5% compared with the first nine months of last year, according to the NDP Group. Meanwhile, the video-game industry is heading for another record year. Thanks to hot new games like Halo 2 for the Xbox, the industry is light-years ahead of the toy business when it comes to buzz. With distractions such as instant messaging, cell phone games and iPods angling for kids’ minds and allowances, the digital revolution is making life miserable for the toy industry.While some hard-to-find toys emerge every holiday season, toymakers are heading into this one without a monster hit. Indeed, there has not been a Furby-style frenzy in years. Of 10 toy segments only two, arts and crafts and dolls, have generated sales growth over a recent 12 month period. Some of the weakest categories like construction sets and action figures are the ones aimed at boys, who suffer the most blisters from the video games. Analysts expect one of the top stocking stuffers this season to be not a traditional toy but the new generation of Nintendo’s Game Boy, the DS, which hit stores last week.The deeper issue is that shifts in play patterns are forcing toymakers to fight for shelf space in a tightening market. Boys in particular seem to be abandoning traditional toys at earlier ages in favor of consumer electronics, trendy video games, PC software and the Internet. The notion that kids are growing more sophisticated and tech-savvy (懂技术的), a trend called “age compression”, has bedeviled toy companies for at least a decade. Action figures, for instance, used to be considered healthy for boys up to age 12. Now the items are mainly marketed to boys 4 to 6. A recent study found that nearly half of the U.S children start on video games at 4 to 5 years old —and 20% at age 3 or younger.Toy companies, of course, have long seen this coming. Mattel attempted to get into educational software in the late 1990s, spending $3.6 million to buy the Learning Company. But it turned out to be a blunder and led to more than $400 million in losses. Later on Mattel got back to building basic brands like Barbie and Hot Wheels. But Bar bie’s sales slump may also be a victim of kids growing older at younger ages.Several of the toys expected to sell well this season are, in fact, those that incorporate video gaming and DVD technologies. Mattel’s Fisher-Price introduced a game system called InteracTV this year, featuring DVDs with characters like Dora the explorer. Hasbro came out with a portable color video player called VideoNow and has been putting classic games like Battleship and Yahtzee into hand-held electronic format.5. At the beginning of the passage, the author implies that[A] video games are designed only for boys.[B] girls are usually not interested in video games.[C] both Anthony and Michaely are good at playing PlayStation 2.[D] children would not like to stop playing Game Boy once they start.6. We learn from the passage that in this holiday season[A] it is hard to find traditional toys in the market.[B] toymakers are planning to design monster toys.[C] no hit toys will come onto the market.[D] Furby will become popular among children.7. The sales of construction sets are decreasing because[A] they are not healthy toys for children.[B] they are very weak and easily broken.[C] they are hard to find on shelves of toy stores.[D] they are aimed at boys who are easily attracted by the video games.8. What has been bothering toymakers for almost ten years?[A] The Internet addiction.[B] The trend of age compression.[C] The sales of action figures.[D] The new generation of Game Boy.9. It is predicted that in this season the popular toys would be[A] hot new game Halo 2 for the Xbox.[B] arts and crafts and dolls.[C] action figures designed for boys aged from 4 to 6.[D] toys that integrate video gaming with DVD technologies.Text CSpace is a dangerous place, not only because of meteors(流星) but also because of rays from the Sun and other stars.Radiation is the greatest known danger to explorers in space. Doses of radiation are measured in units called “rem”. We all receive radiation here on the Earth from the Sun, f rom cosmic rays and from radioactive minerals. The “normal” dose of radiation that we receive each year is about 100 millirem; it varies according to where you live, and this is a very rough estimate. Scientists have reason to think that a man can put up with far more radiation than this without being damaged; the figure of 60 rem has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage — a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of children or even grandchildren.Early space probes showed that radiation varies in different parts of space around the Earth. It also varies in time because, when great spurts of gas shoot out of the Sun, they are accompanied by a lot of extra radiation. Some estimates of the amount of radiation in space, based on various measurements and calculations, are as low as 10 rem per year, while others are as high as 5 remper hour! Mission to the Moon have had to cross the Van Allen belts of high radiation and, during the outward and return journeys, the Apollo 8 crew accumulated a total dose of about 200 millirem per man. It was hoped that there would not be any large solar flares during the times of Apollo moon walks because the walls of the lunar excursion modules (LEMs) were not thick enough to protect the men inside, though the command modules did give reasonable protection. So far, no dangerous doses of radiation have been reported, but the Gemini(双子座)orbits and the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory or in a base on the Moon. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far. At present, radiation seems to be the greatest physical hazard to space travelers, but it is impossible to say just how serious the hazard will turn out to be in the future.10. What make space a dangerous place?[A] The radioactive meteors.[B] The Sun and other stars.[C] Rays from the earth.[D] Rem.11. According to the passage, which of the following is NOT true?[A] The “normal” dose of radiation we rec eive is generally accepted as safe.[B] Scientists are certain that 60 rem of radiation won’t damage man.[C] Harm of radiation is not likely to be seen immediately.[D] We don’t know exactly the seriousness of radiation damage.12. Missions to the moon are dangerous to the explorers because[A] they have to cross the high radioactive area.[B] solar flares may damage the LEMs.[C] they have to stay in space for a long time.[D] they will probably run into meteors.13. How will men effectively protect themselves when they spend long periods in space?[A] By taking special drugs.[B] By wearing special suits.[C] By using a protective blanket.[D] No effective solution has been found yet.14. The example of Apollo is to show[A] the Apollo mission was very successful.[B] protection from space radiation is no easy job.[C] astronauts don’t care about radiation damage.[D] radiation is not a threat to well-protected space explorers.15. The best title for this passage would be[A] The Atmosphere and Our Environment[B] Research on Radiation[C] Effects of Space Radiation[D] Important Protection against RadiationText DA simple computer program that teaches children to distinguish between sounds can dramatically boost their listening skills. It can allow them to progress by the equivalent of two years in just a few weeks, the game’s creator claims.The game, called Phonomena, was devised by David Moore of the University of Oxford, U.K., as an aid for children with language problems, but he says his latest trials also show that it can help any child. Other experts, however, are reserving judgment until independent tests are carried out.Phonomena is designed to improve children’s ability to distinguish between differentphonemes(音素), the basic sounds that form the building blocks of language. Up to a fifth of all children are thought to have problems hearing the differences between some sounds, says Moore, who heads the U.K. Medical Research Council’s Institute of Hearing Research.In the game, children have to distinguish between pairs of phonemes such as the “i” sound from the word “bit” and the “e” from “bet”. They are played one phoneme followed by two more examples, and asked which one matches the first sound. As the game progresses, the phonemes are gradual ly “morphed”(改变) to make them more and more similar, making it increasingly difficult to distinguish between them.With 44 phonemes in English, there are potentially more than 1,000 different pairs, but the game concentrates on just 22 pairs of the commonest and most similar-sounding phonemes.In the latest trials, 18 children aged between eight and ten played the game three times a week for four weeks. Their language abilities were compared before and after exposure to the game using a standard listening test.The team found a dramatic improvement in their language abilities, with listening ages up by an average 2.4 years compared with 12 children who did not play the game. In earlier trials on children with learning difficulties, the speech and language therapists who tested the game reported similar improvements.But Ted Wragg, an expert in education at the U.K’s University of Exeter, warns that such trials can produce misleading results. The improvements could be due to the efforts and attention of teachers and therapists, rather than the game itself. There is a history in education of people and companies making claims about learning products that do not stand up to scrutiny, he says.It is a bit like teaching someone to catch a ball, Moore adds. “Sensor y performance is no different from motor performance. As far as we know, the neural processes driving them both are the same.” And just as playing catch improves hand-eye coordination in other tasks, Moore thinks the phoneme training boosts children’s gene ral language skills.The advantage of using computers, he says, is each game can be tailored to a child’s abilities.An oxford-based company called MindWeavers has been set up to commercialize the game.Similar computer0based language tools already exist, such as those developed by Scientific Learning of Oakland, California. But these are geared exclusively towards children with speech and language problems and involve intensive training.“We don’t believe you need to do this Draconian(严酷的) amount of training for it to do good,” says Moore. He is also exploring the use of phoneme training as an aid to adults learning a foreign language.16. At first, the Phonomena game is designed for[A] adults.[B] disabled children.[C] children with language problems.[D] all children.17. We can infer from the passage that in the game[A] one fifth of the children have difficult distinguishing between sounds.[B] children are asked to tell the differences between similar sounds.[C] the phonemes are becoming increasingly difficult to distinguish.[D] 44 phonemes in English are involved.18. In Ted Wrag g’s opinion,[A] the trial results are not reliable and reasonable.[B] the game is helpful to children with language problems.[C] the trial results are accurate.[D] the trial results show that the game is useless.19. What is the advantage of using computers in Phonomena game?[A] It can provide customized service.[B] It can provide multimedia service.[C] Children can play the game at home.[D] It can improve child’s ability.20. What’s the limitation of the existing computer-based language tools?[A] They are designed exclusively for children.[B] They require too much training.[C] They are too harsh.[D] They do nothing good to language skills.语境词汇Text A1. crackle sparks of electricity <喻>通过电波传递2. anticlimax n.令人扫兴的结尾3. tatter v.扯碎，使变破烂：a tattered flag 一面破旧的国旗4.mainmast n.主桅5. pipe v.召集，召唤6. the veranda deck 舰艇上的游廊7. clutch v.抓住，抓紧Text B1. thumb v.以拇指摆弄n. 大拇指2. blister n.水泡，气泡v.使起水泡3. angle v.谋取；垂钓n.角；角度，观点4. hit n.成功的尝试；击中v.打（击）5. frenzy n.狂乱；极度的激动6. trendy a.时髦的，流行的n.新潮人物,穿着时髦的人7. bedevil vt.使苦恼；折磨8. slump n.经济衰退；消沉v.倒下，陷落；下跌Text C1. radiation n.放射，辐射；放射物，放射线2. cosmic n.宇宙的；广大的，无限的3. probe n.太空探测器；探查v.查究，调查4. spurt n.喷射；忽然的加速、增强vi.喷出，涌出5. accumulate v.积累，聚集；增长6. excursion n.郊游，远足，游览Text D1. distinguish vt.＆vi.区分，辨别2. phoneme n.音素，音位2. exposure n.暴露，揭露；曝光，曝光时间3. scrutiny n.细察，详审4. sensory a.知觉的，感觉的，感觉器官的5. tailor vt.使合适，修改n.裁缝6. exclusively ad.仅仅，专门地；排他地，独占地难句突破Text A1.

It is with great pride and excitement that our school commemorates World Space Day on April 12th, a celebration that transcends mere boundaries and unites us in our shared fascination with the vast expanse of the cosmos.From the moment our ancestors first gazed up at the twinkling stars, the allure of the heavens has captivated the human spirit. Today, we find ourselves living in an era where that primal curiosity has blossomed into a vibrant reality, with humanity's footprints etched upon the lunar surface and our robotic emissaries venturing ever deeper into the unknown.On this momentous occasion, we pause to reflect on the remarkable journey that has brought us to this point. The history of space exploration is a tapestry woven with tales ofunparalleled bravery, unwavering determination, and groundbreaking scientific discoveries. From the pioneering work of visionaries like Galileo Galilei and Isaac Newton, whose theories laid the foundation for our understanding of the cosmos, to the audacious dreamers who dared to reach for the stars, each chapter in this epic saga has propelled us forward, fueling our collective drive to unlock the secrets of the universe.As we gaze upon the night sky, our minds are transported to the pivotal moments that have shaped our understanding of the cosmos. We remember the awe-inspiring sight of Neil Armstrong taking that first small step onto the lunar surface, forever etching humanity's mark on another celestial body. We recall the breathtaking images beamed back from the Hubble Space Telescope, revealing the intricate beauty and complexity of distant galaxies. And we marvel at the astonishing achievements of robotic explorers like the Curiosity rover, which has unveiled invaluable insights into the enigmatic landscapes of Mars.Yet, as we bask in the glory of these accomplishments, we must also acknowledge that space exploration is not merely a pursuit of scientific knowledge but a testament to the indomitable spirit of human endeavor. It serves as a powerfulreminder of what we can achieve when we set our sights on the seemingly impossible and harness the collective genius of our species.The exploration of space has transcended borders, uniting nations in a shared quest to unravel the mysteries of the cosmos. It has fostered international cooperation and inspired generations of young minds to pursue careers in science, technology, engineering, and mathematics (STEM). The profound impact of space exploration extends far beyond the confines of the Earth's atmosphere, influencing virtually every aspect of our lives, from advanced communication systems to cutting-edge medical technologies.As students, we are the torchbearers of this incredible legacy, inheriting the mantle of a generation that dared to dream and challenged the boundaries of human potential.

As we stand in awe of the celestial wonders that adorn the night sky, we are reminded of the vast expanse thatawaits our exploration. Perhaps one day, our footsteps will grace the rusty dunes of Mars, or our robotic ambassadors will venture beyond the confines of our solar system, unlocking the secrets of exoplanets and unveiling the enigmas that have captivated humanity for eons.This is a call to action, a rallying cry for the dreamers, the visionaries, and the pioneers of tomorrow. Let us embrace the spirit of exploration that has guided humanity thus far, and let us pledge to push the boundaries of what is possible. For in the vast expanse of the cosmos, there lie infinite frontiers waiting to be conquered, mysteries yearning to be unraveled, and wonders beyond our wildest imaginations.Today, as we honor World Space Day, let us raise our gaze to the heavens and allow our minds to soar among the stars. Let us revel in the accomplishments of those who came before us while casting our sights towards the boundless horizons that beckon. For it is in the pursuit of knowledge, in the relentless quest to unlock the secrets of the universe, that we truly embody the essence of what it means to be human.The cosmos is our canvas, and we are the artists, painting the narrative of humanity's journey through the vast expanse of space. Let us embrace this opportunity to leave an indelible mark,to inspire generations to come, and to forge a legacy that will echo throughout the ages.篇2The Infinite Frontier: Celebrating World Space DayAs students of the 21st century, we stand at the precipice of a new era of exploration and discovery. The vast expanse of space, once an unyielding mystery, has become our canvas upon which we paint the boldest dreams of humanity. On April 12th, we celebrate World Space Day, a date that carries profound significance for all those who dare to gaze upwards and ponder the infinite wonders that lie beyond our terrestrial confines.From the moment our ancestors first glimpsed the twinkling lights in the night sky, an insatiable curiosity has burned within the human spirit. What secrets do those celestial bodies hold? What lies beyond the veil of our atmosphere? These questions have ignited the imaginations of generations, fueling a relentless pursuit of knowledge that has propelled our species to remarkable heights.The journey into the cosmos began with baby steps, as our primitive understanding of the universe gradually gave way to scientific breakthroughs. From Galileo's pioneering use of thetelescope to Newton's laws of motion, each revelation ushered in a paradigm shift, redefining our perception of the cosmos. Yet, it was the dawn of the Space Age that truly shattered the boundaries of what we believed possible.On that fateful day in 1961, when Yuri Gagarin became the first human to venture into space, the world watched in awe as he orbited our planet, defying the shackles of gravity. This momentous achievement not only symbolized the triumph of human ingenuity but also ignited a fervent race to conquer the final frontier. Nations rallied their resources, pouring their collective determination into reaching for the stars, and the ensuing decades witnessed a flurry of milestones etched into the annals of space exploration.From the awe-inspiring footprints left on the lunar surface by Neil Armstrong and Buzz Aldrin to the breathtaking images captured by the Hubble Space Telescope, each achievement has broadened our horizons and deepened our reverence for the cosmos. We have witnessed the birth of stars and the death throes of ancient galaxies, unraveling the intricate tapestry of our universe thread by thread.Yet, our journey into the unknown is far from over. As we celebrate World Space Day, we are reminded of the boundlesspotential that lies ahead. The exploration of Mars, once a distant dream, is now within our grasp, with robotic emissaries paving the way for future human expeditions.

On World Space Day, let us embrace the spirit of exploration, for it isthrough this unwavering pursuit that we unlock the secrets of the universe and fulfill our destiny as custodians of knowledge, pioneers of discovery, and ambassadors of the infinite.篇3A Voyage Among the Stars: Celebrating World Space DayAs I gaze up at the twinkling celestial tapestry that adorns the night sky, my mind is consumed by a profound sense of wonder and curiosity. The vast expanse of the cosmos, once an impenetrable enigma, has gradually unveiled its secrets to the relentless pursuit of human ingenuity and exploration. It is with great anticipation that our school eagerly awaits the arrival of World Space Day on April 12th, a momentous occasion that commemorates the triumphs and aspirations of space exploration.From the moment our ancestors first cast their gaze upon the heavens, a primal yearning to unravel the mysteries of the universe has been etched into the human psyche. The ancients, while lacking the technological advancements of today, wove intricate mythologies and cosmologies in an attempt to make sense of the celestial bodies that danced across the night sky. Little did they know that their celestial musings would one daypave the way for the extraordinary feats of space exploration that have reshaped our understanding of the cosmos.It was not until the 20th century that humanity's dreams of venturing into the great unknown began to crystallize. The pioneering work of visionaries like Konstantin Tsiolkovsky, Robert Goddard, and Wernher von Braun laid the foundations for the development of rocket technology, propelling us into the realms of space travel. The launch of Sputnik 1 in 1957 marked a watershed moment, igniting the Space Race between the United States and the Soviet Union, and forever altering the course of human history.Yet, it was the Apollo program that truly captured the world's imagination and solidified our place among the stars. On July 20, 1969, the world held its collective breath as Neil Armstrong became the first human to set foot on the lunar surface, uttering those immortal words: "That's one small step for man, one giant leap for mankind." This momentous achievement not only demonstrated the boundless potential of human ingenuity but also served as a poignant reminder that even the most audacious dreams can be realized through unwavering perseverance and determination.Since those pioneering days, space exploration has undergone a remarkable transformation, transcending the boundaries of nations and evolving into a collaborative endeavor that unites humanity in its quest for knowledge and discovery. The International Space Station stands as a shining example of this global cooperation, a celestial outpost where astronauts from diverse backgrounds work in harmony to advance our understanding of the universe and the intricacies of life in space.As we celebrate World Space Day, we are reminded of the countless contributions that space exploration has made to our daily lives. From weather forecasting and global communication networks to advancements in medical technology and materials science, the ripple effects of our cosmic endeavors have profoundly enriched our terrestrial existence. Furthermore, the study of celestial bodies and phenomena has shed light on the origins of our universe and our place within it, prompting us to ponder existential questions that have captivated philosophers and stargazers alike throughout the ages.Yet, our journey among the stars is far from over. As we stand on the precipice of new frontiers, our insatiable curiosity and thirst for knowledge propel us ever forward. The exploration of Mars, once a distant dream, is now a tangible reality, withrobotic rovers and future human missions poised to unravel the secrets of the Red Planet. Beyond our celestial neighborhood, the quest to detect and study exoplanets – worlds beyond our solar system – has opened up a universe of possibilities, igniting speculation about the existence of extraterrestrial life and the potential for future interstellar travel.Moreover, the advent of commercial space enterprises and the democratization of space exploration have ushered in a new era of accessibility and innovation. Private companies are now developing reusable launch vehicles, making space travel more affordable and sustainable, while also pushing the boundaries of what was once thought impossible. This burgeoning industry holds the promise of ushering in a new age of space tourism, where ordinary citizens can experience the wonders of the cosmos firsthand, forever altering their perspective on our fragile yet awe-inspiring planet.As we gather to celebrate World Space Day, let us embrace the spirit of exploration that has propelled humanity to the stars. Let us honor the courageous men and women who have risked their lives in the pursuit of knowledge, and let us inspire the next generation of explorers, scientists, and dreamers to carry the torch of discovery into the vast unknown.For it is through our insatiable curiosity and unwavering determination that we will continue to push the boundaries of what is possible, unlocking the secrets of the universe one celestial body at a time. As we gaze upon the stars, let us remember that our journey among them has only just begun, and that the limitless expanse of the cosmos beckons us to embrace the unknown, to dare greatly, and to never cease in our quest to understand the wonders that lie beyond our terrestrial abode.。

A Compton camera is constructed by arranging twoelectrode split planar germanium semiconductor detectors in front and behind. This Compton camera processes a detection signal obtained from an anode and a cathode of the planar electrode split germanium detector, and can measure at how deep position from the detector surface the interaction of a gamma ray occurs. Moreover, with regard to the direction parallel to the electrode surface of the detector, the interaction position of the gamma ray was able to be measured with high accuracy. Accordingly, spatial resolution is improved by resolving a formula for the kinematics of Compton scattering with excellent accuracy.申请人：Riken地址：2-1, Hirosawa Wako-shi, Saitama 351-0198 JP国籍：JP代理机构：Ziebig, Marlene, Dr. Dipl.-Chem.更多信息请下载全文后查看。

Mae JemisonImagine you are lying on your back, strapped into a chair, with your knees bent in front of you. You feel your heart beating with excitement as you hear a voice on the earphone inside your helmet counting down slowly,” Three, two, one,” Then, beneath you, a deep rumble start as rocket fuel ignites in the huge engines. You① feel a lurch as the docking mechanisms let go, and your rocket begins to rise. This is the moment Mae Jemison has been waiting and working for since 1987. The firstAfrican-American female astronaut-in-training at the National Aeronautics and Space②Administration (NASA) , Jemison is scheduled to “fly” in September 1992. She is to serve as a specialist on Spacelab—J, a joint Japanese—American research project.Mae Jemison was thirty-three when she was selected for NASA’s astronaut training program. Astronaut candidates must have science degree. They must be fit and healthy with normal blood pressure and good eyesight. They must stand between five feet and six feet four inches tall. They must complete a one-year training program that includes water-survival lessons and weightless walks in a huge antigravity tank. On the 1991 mission, astronaut Jemison says that her “responsibility are to be familiar with the shuttle and how it operates, to do the experiments once you get③ into orbit, to help launch the payloads or satellites, and also to do extra-vehicular activities, or space walks.”How did Mae Jemison grow up to become such a special person? Science —especially astronomy—fascinated her from childhood.She also had a strong desire to help other people. Born in Alabama, but raised in Chicago, she studied chemical engineering and African—American culture and history at Stanford University. To help others, she decided to become a doctor. While still a medical student, she went to Cuba and Kenya on study trips, then worked in④a refugee camp in Thailand. She spent three years in West Africa as a doctor with the Peace Corps. When Dr. Jemison finally returned to the United States, she settled in California to practice medicine. And it was then that she decided to reach for the stars.Mae Jemison’s first application to NASA was not successful. Then, in 1986, the⑤Challenger space shuttle exploded, killing all aboard . NASA did not take in any new astronauts for about a year. When it finally reopened its application process, Mae Jemison was ready, and so was NASA. After being selected as a minority astronaut, Mae Jemison received a good deal of attention from newspaper and television. She explained to reporters that the space program and other fields in high technology offer promising careers for African-Americans and other minorities who study hard⑥and make the most of their opportunities .1.The first paragraph is about ______.A.how excited Mae Jemison was when she became an astronautB. how Mae Jemisonbecame an astronautC.how the people usually feel when the rocket they take begins to riseD.what Mae Jemison did after she was able to fly a rocket2.Which of the following statements is true?A.Mae Jemison had a strong desire to become famous.B.Mae Jemison was brought up in Alabama.C.Mae Jemison studied astronomy at Stanford University.D.Mae Jemison studied medicine.3.When did the Challenger space shuttle explode?
