2018-2019学年高桥中学高一上一次月考(含答案)

高桥高一英语试卷II. Grammar and V ocabularySection ADirections: After reading the passage below, fill in the blanks to make the passages coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.I have some good news and some bad news. First, the bad news: Just 21. ________ (have) good grades may not be sufficient to get you your high school diploma. That's because, as of last year, students are required to complete 90 days of practical training and 60 hours of volunteering in order to graduate. Now, the good news: the new requirements are going to give you a head start in coping with the real world 22. ________ ________ _________your school days are over.The Ministry of Education made the changes because it wants students to break out of their cocoons. Much like Mark Twain's famous quote: "I have never let-my schooling interfere with education." the ministry feels there are valuable and necessary lessons 23. ________ (learn) outside of the classroom - lessons such as the responsibilities required in a workplace and, by volunteering, the responsibilities required of a good citizen.The ministry's changes, however, 24. ________ be somewhat problematic. Students 25. ________ (overwhelm) with school work, so where will they find the time? 26. ________ many organizations need volunteers on weekends and you can easily meet that part of the requirement, finding a place to do your practical training will be more difficult. It will probably have to be done during vacations.Many Western companies offer internships(实习机会)and summer jobs to high school students. They see 27. ________ as part of their corporate responsibility and it's also a good way for them to identify potential employees. Chinese companies, however, offer fewer internships and summer jobs, and their programs are not well-develop. Students may just end up sitting around all day. 28. ________ (bad) yet, there are some companies 29. ________ do hire students but just to exploit their labor. There are stories of vocational school students who, as part of their practical training, are sent to factories where they assemble computer parts. They spend long hours on an assembly line and are paid low wages. Not much to learn there 30. ________ how to be tired, bored and broke.Hopefully, your practical experience will be better and you will learn useful lessons. The most important of which is, as one businessman said, "In the workplace, you have to get an A-plus all the time -- being "just good enough" just isn't good enough".Section BDirections: Fill in each blank with a proper word chosen from the box. Each word can only be used once. Note that there isa 3-1 win over Serbia. V olleyball lovers know that the success is in large part due to Lang Ping, the team's head coach, who became the first person to win Olympic volleyball gold as a player and a coach.Dubbed the "Iron Hammer" for her 31. ________ spikes(扣球), Lang played an important role in leading the national volleyball team to 32. ________ a series of world titles in the 1980s -- four world championships and the gold medal in the 1984 Olympics. These achievements earned Lang great praise. Her wedding was 33. ________ on national television and her nickname 34. ________ the spirit of women's volleyball: teamwork and 35. ________.Instead of accepting the government job offer in the sports bureau after retirement like her former teammates, Lang 36. ________ to the United States in 1987 to pursue further studies at the University of New Mexico. She later explained that she was 37. ________ by a desire to learn English, broaden her horizons - and escape her fame.In her 27-year coaching career, Lang has led volleyball teams in Turkey, Italy and the United States, helping them win regional and even world championships. However, her foreign coaching drew fire from some Chinese, who 38. ________ her of forsaking(背弃)China. Even worse, when she started coaching the U. S. volleyball team in 2005 and led them to beat the Chinese team in the 2008 Beijing Olympics, Lang was called a traitor by "patriotic" trolls(恶意挑衅的人)online eventhough she insisted, "I wear another country's colors, but I will always be Chinese."Eight years on, the 39. ________ coach regained her name in her homeland with 40. ________ ability and charisma. As the U. S. volleyball player Nicole Davis said, "She [Lang] is more of a historical figure, more of a sports figure. I mean, she's in the history books. I think that's a beautiful thing."III. Reading ComprehensionsSection ADirections: For each blank in the following passage, there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Cowboy or spaceman? A dilemma for a children's party, perhaps. But also a question for economists, argued Kenneth Boulding, in an essay published in 1966. We have run our __41__, he warned, like cowboys on the open grassland: taking and using the world's resources, __42__ that more lies over the horizon. But the Earth is __43__ a grassland than a spaceship -- a closed system, alone in space, carrying exhaustible supplies. We need, said Boulding, an economics that takes seriously the idea of environmental __44__. In the half century since his essay, a new themselves, want to __45__ its aims and assumptions. What do they say -- and will their ideas take off?To its __46__, ecological economics is neither ecology nor economics, but a mix of both. Their starting point is to recognize that the human economy is part of the natural world. Our environment, they note, is both a source of resources and a sink for wastes. But it is __47__ in traditional textbooks, where neat diagrams trace the flows between firms, households and the government as though nature did not exist. That is a huge mistake.There are two ways our economies can grow, ecological economists point out: through technological change, or through maximum use of resources. Only the __48__, they say, is worth having. They are suspicious of GDP (gross domestic product), a simple __49__ which does not take into account resource exhaustion, unpaid work and countless other factors. __50__, they advocate more comprehensive approaches, such as GPI (genuine progress indicator), a composite(复合的)index that include things like the cost of pollution, deforestation and car accidents. While GDP has kept growing, global GPI per person __51__ in 1978: by destroying our environment, we are making ourselves poorer, not richer. The solution, according to experts, lies in a "steady-state" economy, where the use of materials and energy is held __52__.Mainstream economists are not __53__. GPI, they point out, is a subjective standard. And talk of limits of growth has had a bad press since the days of Thomas Malthus, who predicted in the 18th century, wrongly, that overpopulation would lead to famine. Human beings find solutions to some of the most annoying problems. But ecological economists __54__ self-satisfaction. In 2009, a paper in Nature argued that human activity is already __55__ safe planetary boundaries on issues such as biodiversity and climate change. That suggests ecologist economists are at least asking some important questions, even if their answers turn out to be wrong.41. A. grassland B. nation C. economy D. spaceship42. A. ignorant B. confident C. astonished D. anxious43. A. less B. smaller C. more D. larger44. A. movements B. influences C. limits D. threats45. A. revolutionize B. realize C. resemble D. reject46. A. challengers B. learners C. advocates D. professors47. A. addressed B. ignored C. opposed D. reflected48. A. advanced B. former C. latter D. scientific49. A. number B. product C. idea D. measure50.

A. impressed B. involved C. concerned D. appointed54. A. call for B. contribute to C. warn against D. refer to55. A. setting B. overstepping C. extending D. redrawingSection BDirections: Read the following two passage. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)High school freshmen always have a lot of questions on their minds. "What can I do when I grow up?" is one of them. It's definitely not too early to start thinking about his tough question. The following tips may help equip you for your future career.●Think beyond gradesGetting good grades in high school is important, but focusing only on straight A's could go wrong. Spending too much time on your schoolwork will leave you little time to explore opportunities outside of the classroom. Extracurricular(课外的)activities are necessary because they serve as a form of career exploration. They can help you figure out your work preferences, like whether you are a "people person(擅长交际的人)" or prefer to work alone. Nowadays, most well-known colleges care about candidates' experiences as much as their grades.●Seek advice from grown-upsTalk to your parents, teachers and school counselors(顾问)about how they started their careers. Even though you're interested in the careers they are in, it would be useful to learn about the process which got them where they are now. If you find your friend's mother doing a worthwhile job by chance, ask her if job shadowing(体验工作)is possible in her company during vacation. After all, seeing a typical day in the position you have an interest in can be an invaluable experience.●Start your search onlineIf you really have no idea what you can do when you grow up, take online career quizzes to get ideas about what professions naturally match your skills, interests and personality traits(特点). For the time being, you just need to focus on finding a field or two that interests you, rather than a specific career. Chances are you'll change your mind several times before finding a career that you want to stick to. Starting to explore career options now can at least help you decide what your potential major might be.56. Spending some time taking part in after-school activities can help high school students ________.A. get A's in all subjectsB. explore their work preferencesC. have access to prestigious universitiesD. get along with their classmates57. Grown-ups may help high school students by _________.A. starting a business with themB. teaching them occupational skillsC. sharing their career paths with themD. providing an opportunity for job shadowing58. It is suggested that high school students find out their _______ from online career quizzes.A. possible professionsB. main disadvantagesC. specific occupationsD. ideal majors59. This article was probably written by a __________.A. college professorB. school counselorC. advertising managerD. computer programmer(B)According to the old nursery rhyme(童谣), "Girls are made of sugar and spice and everything nice. Boys are made of snakes and snails and puppy dog tails." Yes, boys and girls are different, and in the modern world, "sugar and spice" seems to win out over "snakes and snails." At least, Chinese education officials seems to think so.The officials point to statistics(统计数据)which show 80 percent of elementary and middle school teachers are women and that girls consistently outperform boys in the classroom. Moreover, they say this "feminization(女性化)" of schools is making boys soft and preventing them from becoming "real" men. The solution to the problem (if it is a problem),the officials say, is to hire more male teachers and introduce a more boy-centered curriculum which can "salvage masculinity(男子气概)in schools."Some steps in this direction have already taken place. A teachers' college in Fuzhou has lowered its admission requirements for boy students and it offers full scholarships and guaranteed job when they graduate. And a school in Shanghai has all-boy classes, hoping that segregating them from girls will improve their grades.But one wonders if these changes are really necessary. Does it matter if your teacher is a man or a woman as long as he or she is a good teacher? (By the way, Shanghai has the best teachers in the world!) And are boys really becoming soft? There are a number of studies about these questions, but they are mostly inconclusive. A study from South Korea says girls do better when taught by a female teacher, but there seems to be no corresponding effect when boys are taught by men. As for boys becoming soft, this is purely subjective - older generations look at young generations and always find them wanting.Having said that, the education authorities are right to encourage more men to become teachers. Yes, the pay is low and so is the status, but teaching offers much greater rewards: the love and appreciation of your students and the satisfaction you get from helping young people learn and grow. And male teachers do bring a different "vibe(气氛)" to the classroom. Maybe it's the "snakes and snails."60. The word "inconclusive" in the sentence "There are a number of studies about these questions, but they are almost inconclusive" in Paragraph 4 probably means "__________".A. incorrectB. questionableC. accurateD. profitable61. According to the article, all the following statements are wrong EXCEPT that ________.A. women account for the vast majority of teachers in Chinese collegesB. top students in Fuzhou will be offered a guaranteed job after gr4aduationC. there has been no scientific evidence that boys do better when taught by men teachers so farD. it is not a good choice for men to get into teaching62. The author's attitude towards recruiting more male teachers to salvage masculinity in schools is _______.A. supportiveB. casualC. unclearD. criticalSection CDirections: Read the passage carefully. Fill in each blank with a proper sentence given in the box. Each sentence can be usedbulky(笨重的)3D glasses in theaters. While audiences in the rest of the world have cooled toward 3D movies, their popularity in China is still growing.Now, however, that may be changing, too.In late August, Jason Bourne(《谍影重重5》), the fifth installment(分集)of the Bourne action-adventure series, was released in China in a 3D version. 63. __________ One moviegoer said, "There [was] a line of people throwing up in the restroom of the cinema I went to ... I'm not exaggerating." What made them sick was not the content of the movie, but the style of the movie - the camera never stops moving. Paul Green-grass, the director, uses a hand-held camera which always seems to be shaking. 64. __________ This style is meant to create tension and excitement, and to make the audience feel slightly disoriented(晕头转向的). However, when 3D effects are added, audiences can become very disoriented, to the point where they feel they've just spent two hours on the Diving Coaster at Happy Valley.Jason Bourne wasn't meant to be a 3D movie. 65. __________ Hollywood studios have done this with other movies,too. It's a cheaper way to make 3D movies and it also allows the studios and theater operators - to increase ticket prices and make bigger profits. In plain American slang(俚语): The customers are being "played for suckers(被当做傻瓜)"!After the Jason Bourne experience, this disdain for the ticket-buying public has gotten some push-back. One Weibo blogger wrote, "Please don't offer 3D just to grab money anymore. Chinese people are not stupid. We can vote with our feet and money." Well, maybe. 66. __________ Wanda Group, in addition, is pushing ahead with its plan to add 4,000 more 3D theaters across China. It seems both Hollywood and Wanda are betting on the future of 3D in China, but they shouldn't get too complacent(自鸣得意的)and confuse 3D glasses with rose-colored glasses.I.

AA painting of a famous artist could cost several million dollars in the market. This is why many artworks-even those that are housed inside highly guarded museums-go missing. Here is a list of some of the most famous paintings that were lost, stolen or destroyed.Vincent Van Gogh' s Poppy FlowersThis artwork was housed at the Mohammed Mahmoud Khalil Museum in Cairo. It was first lost in 1977, but was recovered 10 years after. The second time this same Vincent Van Gogh painting was stolen was in August of 2010. The painting is estimated (估价) to be worth something between $50 and $55 million.Pablo Picasso' s Le Pigeon Aux PetitsStolen on May 20, 2010, this painting by Spanish painter Pablo Picasso is worth $28 million. It was stolen at the Musee d' Art Moderne de la Ville de Paris, along with five other artworks. However, the thieves threw the painting away in a trashcan when they were caught. But that container was emptied before the authorities got there. It was feared that the painting was already destroyed.Paul Cezanne' s View of Auvers Sur OiseLost on December 31, 1990, this artwork that used to be on exhibition at the Ashmolean Museum in Oxford was stolen the night before the city's Millennium celebration. The thieves planned the robbery in time with the fireworks exhibition during peak of the celebrations. This artwork is estimated to be worth $5 million.Covert Flinck' s Landscape with an ObeliskStolen on March 18, 1990, this artwork was at the Isabella Steward Gardner Museum in Boston. This painting by Covert Flinck was previously believed to be a Rembrandt creation. A huge cash reward of $5 million will be given to the person who can provide information leading tothe recovery of the painting.21. In which of the following cities was Le Pigeon Aux Petits stolen?A. Cairo.B. Paris.C. Oxford.D. Boston.22. Who was mistakenly thought to create Landscape with an Obelisk?A. Pablo Picasso.B. Paul Cezanne.C. Covert Flinck.D. Rembrandt.23. What can we infer about the four artworks mentioned in the text?A. Some of them are given an approximate price.B. They all are stolen when on exhibition.C. Some of them are lost 30 years.D. Some of them have been found so far.BIn the US TV series Friends, Rachel Green is a classic example of a pushover. More often than not, she gives in to her childhood friend Monic a Geller’s demands on trivial (琐碎的)things such as what to eat for a lunch, even if she has her own preference.Like Rachel, some people find themselves being constantly influenced by others. There are all kinds of reasons why they would act as easy-going and flexible as Rachel does. Maybe the topic of discussion just isn’t something that interests them. Take household issues for example. Most men don’t get overly excited at the idea of buying new kitchenware. So it’s not uncommon to hear a husband tell his wife “you can buy whatever you like” or “I don’t care”. Technically, he’s being a pushover. But he’s also being flexible, avoiding any future conflict.Have you ever been traveling with friends and disagreed with them about which scenic spots you should vi sit? Maybe you had your own opinions on where to go, but you just said, “Oh, I’m fine if we don’t go there. It’s your call.” Being easy-going is certainly a virtue that helps sustain good relationships and makes you a person that others want to be around. It can make you look like a pushover to others, but if you’re OK with that, then it’s fine. There’s nothing wrong with it.But if you hate being thought of as a pushover, then maybe it’s time you should learn to say “no”. No is a simple yet powerful word. You don’t have to do or participate in anything that you don’t want to. It won’t upset the people around you half as much as you fear it will, and if it does then they will get over it in time. Taking a firm stand clearly defines your likes and dislikes, whichcan also be an endearing (讨人喜欢的)character trait.24.What is a pushover likely to do when going to the cinema with a friend?A. Hesitate about which film to see.B. Choose to see the film her friend likes.C. Quarrel with her friend about what to see.D. Persuade her friend to see her favorite film.25. When it comes to buying kitchenware, a husband tends to tell his wife “you can buy whatever you like” because ________A. He wants to show his language techniques.B. He would like to please his wife.C. He just wants to avoid conflict in future.D. He is a caring husband26.What does the underlined word “It” in Paragraph 4 refer to?A. Doing anything friends ask you to do.B. Hating being considered as a pushover.C. Saying “no” to somet hing you don’t want.D. Being easy-going to the people around you.27.What’s the author’s attitude towards being a pushover?A. Neutral.B. DisapprovingC. Favorable.D. Reserved.CMy son Mason recently turned three and to celebrate it, we had a cookout with friends. Fortunately, many friends have kids his age. When kids congregate (聚集) there is a sense that chaos is right around the corner. Once the screaming begins, little bodies scatter to their moms and dads and fingers point at the perceived wrongdoer. This happens because they don’t know how to work together. They can learn, however.Interestingly similar enough, when the new school year begins, teachers putting the students in groups and expecting them to work together on a common task, things will break down. The teacher, wrongly assuming students are unwilling to work together rather than unable, will say things like “Work together,” or even “You are in ___ grade now. You should be able to cooperat e.” The teacher may even go as far as putting students back into rows because they do not seem ready to work in teams. Often, though, students want to work together, they just don’t know how. Fortunately, just like Mason and his friends, all students can learn to be effective members of a team.In any academic discipline, the ability to function as a team requires a host of skills. Becauseteamwork skills translate across content areas and provide the foundation for learning in today’s classrooms, they demand significant attention in our classrooms. So, how can teachers support students in acquiring these skills?Teachers can best teach teamwork skills early by having students practice them with activities that are independent of academic content. Depending on students’ ages, teachers may introduce one or more of the following teamwork skills during activities: developing and sharing ideas, listening, positive behavior, individual participation, and coming to agreement. Specifically, teachers should work with students to establish a common understanding of the desired skills and model examples and nonexamples before allowing them to practice on their own. Fortunately, there is no shortage of activities that will get students eager to think and work together. In addition to more well-known team-building activities, such as the “human knot,” there has recently been an influx (流入) of stand-alone team activities known as STEM activities.28. The underlined sentence in Para1 is written to ___________.A. picture a scene of kids playing together noisilyB. indicate the kids’ lack of ability to look after themselvesC. express the writer’s affection to the lovely kidsD. describe the kids’ reaction when they are in conflict29. The teachers try to persuade the students to cooperate on the assumption that ___________.A. the students should be effective team members naturallyB. the students are lacking in cooperative abilityC. the students don’t intend to cooperate wellD. the students need to be trained for cooperative tasks30.We can learn from the passage that_____A. The students are unwilling to work together.B. Teamwork indeed requires a wealth of skills.C. Teachers can best teach teamwork skills early by having students practice them with activities related to academic content.D. There are limited activities that get students trained in teamwork skills.31. What is the best way to teach the students teamwork skills in classrooms?A. Guide the students to have an understanding of teamwork skills.B. Let them enjoy stand-alone activities like STEM.C. Inspire the students to think positively.D. Practice their teamwork skills during activitiesDDon't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area-think of a star ten times bigger than the sun squeezed into a ball approximately the diameter (直径) of New York City. The result produces such a strong gravitational field that nothing, not even light, can escape. In recent years, NASA instruments have painted a new picture of these strange objects that are, to many, the most fascinating objects in space.The idea of an object in space so massive and dense (密度大的) that light could not escape it has been around for centuries. Most famously, black holes were predicted by Einstein's Theory of General Relativity, which showed that when a massive star dies, the center of the star falls in upon itself, or falls apart. When this happens, it explodes part of the star into space and leaves behind a small core with its great density. If the core' s mass is more than about three times the mass of the sun, then the force of gravity is greater than all other forces and produces a black hole.Scientists can't directly observe black holes with telescopes that detect (探测) x-rays, light, or other forms of radiation. We can, however, infer the presence of black holes and study them by detecting their influence on other matter nearby. If a black hole passes through a cloud of matter, for example, it will draw matter inside in a process known as addition. A similar process can occur if a normal star passes close to a black hole. In this case, the black hole can tear the star apart as it pulls it towards itself. As the attracted matter accelerates and heats up, it gives off x-rays that radiate into space. Recent discoveries offer some evidence that black holes have a dramatic influence on the neighborhoods around them - giving off powerful gamma ray bursts, swallowing nearby stars, and accelerating the growth of new stars in some areas while postponing it in others.32. Why does a black hole have such a powerful gravity?A. Its area is small.B. It is empty space.C. Its density is great.D. It contains much light.33. How many stages are there from a massive star to a black hole?A. Two.B. Three.C. Four.D. Five.34. How do scientists research black holes?A. By studying matter nearby them.B. By observing them with telescopes.C. By collecting some light from them.D. By receiving powerful gamma ray bursts.35. What can be a suitable title for the text?A. The Birth of a Black HoleB. The First Picture of a Black HoleC. Some Unknown Secrets of Black HolesD. A New Scientific Discovery:Black Holes第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

But it doesn't. Here is another situation. Perhaps you are not feeling well. The only thing you want to eat is a big bowl of chicken soup, like your mom used to make when you were sick as a child. Food cravings are a strong desire for a specific type of food. And they are normal.Scientists at the website How Stuff Works compare hunger and cravings this way. Hunger is a fairly simple connection between the stomach and the brain. They even call it simply “stomach hunger.” When our stomachs burn up all of the food we have eaten, a hormone (荷尔蒙) sends a message to one part of the brain for more food, which regulates our most basic body functions such as thirst, hunger and sleep. The brain then produces a chemical to start the appetite and you eat. Hunger is a function of survival.A craving is more complex. It activates brain areas related to emotion, memory and reward. These are the same areas of the brain activated during drug-craving studies. Because of this, some scientis ts call food cravings “mind hunger.” People often crave foods that are high in fat and sugar.Foods that are high in fat or high in sugar produce chemicals in the brain. These chemicals give us feelings of pleasure.In a 2007 study, researchers at Camb ridge University found that “dieting or restricted eating generally increases the possibility of food craving.” So, the more you deny yourself a food that you want, the more you may crave it. However, fasting is a bit different. They found that eating no food at all for a short period of time lessened food cravings.So, the next time you crave something very special, know that your brain may be more to blame than your stomach.4.

The disappearance of appetite.7. In which column of a newspaper can you see this passage?A. EducationB. EntertainmentC. ScienceD. EconomyCRenaissance is a French word. It means “rebirth”. It’s a strange name for a period of history. What was it that was reborn during the Renaissance?To answer this question, we need to look back at the time of the Roman Empire. At this time Roman artist, scientists and writers influenced by Greek ideas were the world’s most advanced. They had become skilled observers of the natural world around them, and had become experts in studying animals, plants, the human body or the stars and planets. They wrote down their ideas about what they saw, and based their theories about the world on their observations.During the fourth and fifth centuries the Roman Empire slowly broke down. Many of theRoman’s art and sculptures were destr oyed and some manuscripts were lost as well. But most importantly, some of the ancient attitudes were lost. A questioning approach to the world was replaced by an unquestioning one.Why did this happen? One reason was to do with the influence of Christian Church. Through the thousand years following the fall of the Roman Empire, the Church controlled many aspects of life including education and learning. The Church ran all the universities and thought that the aim of a university should be to teach old ideas more clearly, not to introduce new ones. The scholars in the universities were expected to study God and heaven from the Bible and ancient books, rather than the world around them.Take medicine, for example. The main textbook for doctors had been written by Greek doctor called Galen more than a thousand years earlier. But when Roger Bacon, a thirteen-century priest, said that a new approach to medicine was needed, doctors should do their own original research instead of reading writers from the past such as Galen, the Church put him into prison.By the time of the fourteenth century, however, some parts of Christian Church were becoming less strict about their ideas and there was a new state of mind among artists, doctors and scientists. People wanted to find out more about the world by studying it. This attitude of investigation had been common in classical scholars, and it was “reborn” during the Renaissance.8. We know from the text that scientists at the time of the Roman Empire believed in _________.A. their companion’s observationsB. what they saw with their own eyesC. what they learned from GreeksD. the most advanced theories at that time9. We can infer that students in the Church-controlled universities might_________.A. have good memoriesB. change their beliefsC. be lacking in creativityD. be interested in astronomy10. Roger Bacon was put in prison because he _________.A. give up being a priestB. challenged the ChurchC. did some research secretlyD. showed no respect for Galen11. The text probably comes from a book about _________.A. medicineB. historyC. religionD. educationDNASA might be famous for sending rockets up to space quickly. But it will be more famous formaking your next holiday come more quickly.The space agency is working on a new plane, which could solve the problems of supersonic(超音速的) flight and vastly increase the speed of journeys abroad. If successful, the plane would be able to fly between New York and London in just three hours. And it would reduce the time spent flying other journeys by a half, since it could be used more broadly. Until now, the problem with such planes has been the sonic boom, made famous by the original Concorde(协和客机). That happens when a plane reaches supersonic speeds.It is a thunderous noise that upsets people on the ground— disturbing animals and even causing physical problems to materials and houses underneath. It was that effect that led Congress to ban such planes from being used over the US land, a decision that in turn was responsible for Concorde's failing to be commercially used.In view of the problem, the space agency has developed a new technology and tried it out in wind tunnels, and now believes that it could be put to commercial use. That plane will fly as high as 55,000 feet—far higher than normal planes—and make a sound of only 60 decibels. That's far less than 90 decibels thrown out by normal planes, and is roughly in line with a car on the motorway or a busy restaurant.“As long as we can get endorsement from the general public, the plane will probably be something that's acceptable,” said Peter Coen, project manager for NASA's commercial supersonic research team, in a new Bloomberg report. “If we get approved, we will have the full-sized version of the plane tried out and the plane will be put into use.”12. Why does the author mention Concorde?A. To suggest the rapid development of planes in the USA.B. To make us know the negative effect of the sonic booms better.C. To introduce how a commercial plane is designed.D. To show us that Concorde finally failed to be commercially used.13. What is the fourth paragraph mainly about?A. The basic data of the new plane.B. The working principle of the new plane.C. The problems of the new plane.D. The potential market of the new plane.14. What does the underlined word “endorsement” in paragraph 5 mean?A. responseB. commitmentC. investmentD. agreement15. Why does the author write the passage?A. Because he wants to inform people of NASA's new plane.B. Because he wants to prove the disadvantages of supersonic flight.C. Because he wants to explain why speed matters in supersonic flight.D. Because he wants to clarify some misunderstandings about commercial planes.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。
