Ⅱ. Grammar and vocabularyDirections:After reading the passage, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in the blank with the proper form of the given word; for the others, use one word that best fits each blank.AElectronic devices can seem like __21__ “third party” in some relationships because some partners spend more time on them than with each other.When Amanda Gao, a 26-year-old white-collar worker in Beijing, went to a hotpot restaurant with her boyfriend on Friday night several weeks ago, she expected that they would have a good time together. To her disappointment, however, it did not turn our that way later. As soon as they __22__ (lead) to their seats and she began to order dishes, he buried himself in his mobile phone.“It seemed that his phone was making its way __23__ us. A date that __24__ have belonged to us turned into one where my boyfriend dated a their party and I felt left out.” Gao said. Some people, like her, have found that electronics have been sabotaging(破坏)their romantic relationships.A study, __25__ (publish) in the journal Psychology of Popular Media Culture in April 2017, questioned nearly 200 college aged adults who were in committed relationships to report on their and their partner’s smartphone dependency. The results showed people who were more dependent __26__ their phones were less sure about their relationships, and people who considered their partners excessively(过度地)dependent on their devices were __27__ (satisfied) in their relationship.Lin Yuan, a relationship advisor in Beijing, noted that __28__ more and more electronics come out and spice up people’s lives, they are at the same time becoming a third party in relationships, especially for young people.Lin said she knew of some people who suggest that electronics should be kept out of bedrooms, __29__ she considered challenging and hard to be put into practice for most couples. She recommended that __30__ people are feeling neglected in their relationship, they need to respectfully let their partners know their feeling. “Communication is always the best and the most efficient way,” she said.Section BDirections: Complete the following passages by using the words in the box. Each word can only be used once. Note that there is one word more than you need.Robert Frost had aimed to be a poet since he was a teenager. But the American literary icon would not publish his first book of poetry until he was 39, and his best works would not follow until he was well into middle and old age. “Young people are good at discovering. They have a __31__ here an d there. It is like the stars coming out in the early evening,” he __32__ at age 63, but “it is later in the dark of life that you see forms, patterns.Frost’s __33__ journey to fame during the “dark of life,” however, is far from the road less taken. Despite science, society and Silicon Valley’s common belief that creativity, innovation andexcellence are the near-exclusive province of the young, a surprising number of late bloomers mark the records of human history -- women and men who __34__ years of hardship, failure and missed opportunities before making an impact in the later stages of life. And once you move past the impressive stare of history’s Mozart - like geniuses, you find that late bloomers are quite __35__: in fact, there are many more roads to becoming an old master than a young prodigy.Sometimes you don’t discover your passion in life until you’ve done some other things first. Sometimes you don’t get the opportunity to make the most of your experiences until relatively late in l ife. Ray Kroc, the founder of McDonald’s, didn’t start building his business empire until he was 53 years old. Until that point, the former Red Cross ambulance driver was a traveling salesman, peddling milk shake machines and paper cups. “ I was a(n) __36__ success all right,” Kroc wrote in his autobiography, “but 30 years is a long, long night.”Sometimes, instead of opportunities, life __37__ obstacles on the road to success. It wasn’t until Laura Ingalls Wilder turned 65 that her epic Little House on the Prairie series was published. By then, she had already devoted decades to being a farm wife and mother, schoolteacher, loan officer and newspaper columnist, and she had endured more than her fair __38__ of hardship, from droughts to house fires. Another influential writer, Miguel de Cervantes, wrote Don Quixote in his late 50s after an eventful life in which he spent years behind bars and as a captive of Barbary pirates.Therefore, unlike the youthful genius, whose rocket-fast __39__ impresses as well as depresses the rest of the world, the late bloomer demonstrates what is possible as people __40__ their own versions of full bloom.Ⅲ. Reading ComprehensionSection 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.Today’s cinema has improved a great deal in presentation. Gone are the golden days when eager crowds were packed on wooden benches in poor buildings, which seemed to be about to __41__ in the next minute. Audience were staring, with great interest, at the funny and amusing movements of silent figures on the screen. It was only through the body movements and facial expressions that the character’s feelings could be __42__ to the audience. However, film goers all the same turned a blind eye to the __43__ cinema surroundings and seemed crazy about almost all the films. Box office hits were a normal thing and stories about movie stars took full __44__ of the newspapers. They were __45__ with almost all positive wordings compared with today’s pitiful stars who are all the time alert to such news as divorces or affairs.Nowadays, it is quite easy to find a cinema that exceeds the hotel luxury. Cinemas are spacious, well-lit places where one can kill time in comfort. Small favors offered by modern cinemas such as the well-printed booklets, which are __46__ available, the mouth-watering snacks on sale and even the gifts are all sending the implied message to the audience that the film to watch will provide the equivalent __47__. Audience, on the other hand, don’t always __48__ to story. Before a film is released, the potential spectator is usually exposed to a(n) __49__ of advertisements. Film trailers are seen everywhere and crew interviews are televised. And in tempting people to enter cinemas, second to none is __50__.

What’s more amazing is that these plants occur naturally (in special environments) in every state. In fact, they’re found on every continent except Antarctica.You’ve probably seen a Venus’ flytrap. It’s often sold in museum gift stores, department stores, and even supermarkets. A small plant, it grows 6 to 8 inches tall in a container. At the end of its stalks(茎)are specially modified leaves that act like traps. Inside each trap is a lining of tiny trigger hairs. When an insect lands on them, the trap suddenly shuts. Over the course of a week or so, the plant feeds on its catch.The Venus’ flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous(食肉的)Plant Society’s Newsletter. Note: Despite any science-fiction stories you might have read, no meat-eating plant does any danger to humans.Dr. Meyers-Rice says a plant is meat-eating, only if it does all four of the following: “attract, kill, digest, and absorb” some from of insects, including flies, butterflies, and moths. Meat-eating plants look and act like other green plants -- well, most of the time.All green plants make sugar through a process called photosynthesis(光合作用). Plantsuse the sugar to make food. What makes “meat-eating” plants different is their bug-catching leaves. They need insects for one reason: nitrogen. Nitrogen is a nutrient that they can’t obtain any other way. While almost all green plants on our planet get nitrogen from the soil, “meat-eating” plants can’t. They live in places where nutrients are hard or almost impossible to get from the soil because of its acidity. So they’ve come to rely on getting nitrogen from insects and small animals. In fact, nutrient -rich soil is poisonous to “meat-eating” plants. Never fertilize them! But don’t worry, either, if they never seem to catch any insects. They can survive, but they’ll grow very slowly.56. According to the passage, carnivorous plants ________.A. only grow in wild fieldB. are rare to seeC. are as common as fliesD. cannot grow on Antarctica57. Venus’ flytrap preys on insects with ________.A. its numerous long an thin stalksB. a container where it growsC. its insect-catching leavesD. the lining of tiny trigger hairs58.

It can be considered a branch of both philosophy and education. Education can be defined as the teaching and learning of specific skills, and the imparting of knowledge, judgment and wisdom, and is something broader than the societal institution of education we often speak of.Many educationalists consider it a weak and imprecise field, too far removed from thepractical applications of the real world to be useful. But philosophers dating back to Plato and the Ancient Greeks have given the area much thought and emphasis, and there is little doubt that their work has helped shape the practice of education over the millennia.Plato is the earliest important educational thinker, and education is an essential element in “The Republic” (his most important work on philosophy and political theory, written around 360 B. C.). In it, he advocates some rather extreme methods: removing chil dren from their mothers’ care and raising them as wards of the state, and differentiating children suitable to the various castes(社会等级), the highest receiving the most education, so that they could act as guardians of the city and care for the less able. He believed that education should be holistic(全面的), including facts, skills, physical discipline, music and art. Plato believed that talent and intelligence is not distributed genetically and thus is to be found in children born to all classes, although his proposed system of selective public education for an educated minority of the population does not really follow a democratic model.Aristotle considered human nature, habit and reason to be equally important forces to be cultivated in education, the ultimate aim of which should be to produce good and virtuous citizens. He proposed that teachers lead their students systematically, and that repetition be used as a key tool to develop good habits, unlike Socrates emphasis on questioning his listeners to bring out their own ideas. He emphasized the balancing of the theoretical and practical aspects of subjects taught, among which he clearly mentions reading, writing, mathematics, music, physical education, literature, history, and a wide range of sciences, as well as play, which he also considered important.During the period of Middle Age, the idea of Perennialism was first formulated by St. Thomas Aquinas in his work “De Magistro”. Perennialism holds that one should teach those things deemed to be of everlasting importance to all people everywhere, namely principles and reasoning, not just facts (which are apt to change over time), and that one should teach first about people, not machines or techniques. It was originally religious in nature. and it was only much later that a theory of worldly Perennialism developed.During the Renaissance(文艺复兴), the French doubter Michel de Montaigne (1533-1592) was one of the first to critically look at education. unusually for his time, Montaigne was willing to question the conventional wisdom of the period, calling into question the whole structure of the educational system, and the assumption that university-educated philosophers were necessarily wiser than uneducated farm workers, for example.63. Why do many educationists consider philosophy a ‘week and imprecise field’?A. It is the practical applications of the real world.B. Its theoretical concepts are easily understood.C. It is irrelevant for education.D. It is not practically applicable.64. What is the difference between the approaches of Socrates and Aristotle?A. Aristotle felt the need for repetition to develop good habits in students; Socrates felt that students need to be constantly questioned.B. Aristotle felt the need for rote-learning; Socrates emphasized on dialogic learningC. There was no difference.D. Aristotle emphasized on the importance of paying attention to human nature; Socrates emphasized upon science.65. According to the passage, the underlined word “Perennialism” most probably refers to something ________A. that is unnecessary.B. that is of ceaseless importance.C. that is abstract and theoretical.D. that exists no more.66. Why did Aquinas propose a model of education which did not lay much emphasis on facts?A. Facts are not important.B. Facts do not lead to holistic education.C. Facts change with the changing times.D. Facts are frozen in time.Living off gridWhen you need electricity, you just plug in the machine and switch it on. If you need water, you turn on the tap. __67__ For many people, these facilities are the basics of civilized society and the idea of living without them seems risky. Yet for a growing number of people, the idea of living off grid -- without electricity, water or sewage -- is an increasingly attractive lifestyle.Off-gridders do not have to give up electricity or a modern lifestyle -- some choose to, but most use small hydroelectric power systems, solar panels or windmills to generate enough power for their needs. Heating and cooking needs are met by solar energy or wood burning systems, and toilet facilities range from non-water toilets to outside compost toilets. __68__ It ranges from traditional yurts (a type of tent) to luxury houses with high-speed internet and central heating. Whether they live in simple homes or luxury houses, what they all have in common is that their lifestyles do not create any pollution or carbon emissions -- the ultimate goal for off-gridders.Around 100,000 people are thought to be living off grid in the UK now. __69__ They grow their own food, home-school their children and provide their own medical care. They are people who have been priced out of the housing market or who have grown disillusioned with what modern society can offer and who decides that an alternative lifestyle isn’t a pipe dream, but a viable option.Apart from living an alternative lifestyle, cost is big factor in choosing to live off - grid. Off - grid houses are far cheaper to build than ordinary homes since they don’t need to be connected to the electricity or water supplies and even road access is not necessary. Materials tend to be cheaper, too. Popular options include straw or old tyres and cement.Surprisingly, the biggest problem off - gridders face is not building their homes or becoming self - sufficient but getting permission to build. Rural ares away from town are the perfect choice but these are often protected by law from construction of any kind or have building restrictions. There are new several websites dedicated to land-sharing so that the costs of buyingland and getting permission can be shared, and there are increasing numbers of off - grid communities. __70__ Off - gridding could soon be common all over Europe and America.Ⅳ. Summary WritingDirections: Read the following passage. Summarize in no more than 60 words the main idea of the passage and how it is illustrated. Use your own words as far as possible.In spite of all of the years spent in school preparing to enter the workplace, many recent graduates say that they struggle with the transition from classroom to career world and have difficulty adjusting to life on the job.Writer and editor Joseph Lewis suggests one reason why this is the case. Lewis believes that most of our school experiences -- from childhood through university -- are fairly predictable, while life in the working world is far more ambiguous. In school, for example, the pattern stays more or less the same from year to year. In the workplace, however, constant change is the norm, and one has to adapt quickly. A project you are working on this month might suddenly change next month or next week, and it’s often hard to anticipate what you’ll be doing six to twelve months from now.Another problem that graduates entering the workforce encounter is that they are unprepared to think analytically. In school, many students including those in college, spend a lot of time memorizing facts and repeating what they “learned” on tests. But in the workplace employees are often expected to think critically and make decisions about their work, not just follow a supervisor’s instructions.Finally, many recent graduates say that one of the biggest difficulties they face is adapting to teamwork on the job. In some ways, school does prepare one for collaborative nature of the workplace. Learners sit classes every day with many other students. They must listen to others’ opinions, participate at times in group discussions, and learn how to get along outside the classroom. Nevertheless, in school, a student normally works independently to complete most tasks and receives a grade according to how well he or she has done. In the workplace, however, employees must regularly interact with others and are often dependent on their co - workers for their success.第Ⅱ卷Ⅰ. Translation71. 在任何情况下,坚持原则、明辨是非都是明智的行为。

The town was little more than a village serving ranchers when the United States took possession of it in 1846 during the war with Mexico.San Francisco sprang into a city overnight because of the nearby discovery of gold in 1848. A great rush to California took place. Wagon trains plodded their dangerous way across 2000 miles of prairie and mountains, while hundreds of sailing vessels made the equally hazardous trip around the Horn. The vessels disgorged thousands of passengers -- then the crews deserted their ship and hundreds of vessels were left to rot in the bay. Within two years, California had enough population to become a state and San Francisco was for many years the hub of that newly-arrived population.The city's present popularity is due to an excellent climate, an easy style of living, good food, and numerous tourist attractions. The city is famous for its cable cars which "clang and bang" up the steep hills, and for its excellent seafood stalls along the wharf. Most visitors arriving from nations in the Pacific Basin spend several days getting to know the town.1. According to this article, who were the first Californians?A. deserters from sailing shipsB. Spanish ranchersC. gold minersD. tourist2. San Francisco's appeal includes all of the following factors_______.A. attractive lifestyle, good seafood, desirable weatherB. tourist attractions, extreme seasons, cable carsC. wagon trains, gold mining, good climateD. cable cars, pleasant climate, flat terrain3. San Francisco today is a thriving city because of_______.A. heavy industryB. governmental headquartersC. Gold miningD. trade and tourism4. In which year did California become an American state?A.1850B.1852C.1846D.18485. Which word is the synonym of the underlined word “hazardous” in paragraph 2.A. beneficialB. acquisitiveC. riskyD. vitalBIn order to host the Olympics, a city must submit a proposal to the IOC. After all proposals have been submitted, the IOC votes. If no city with the fewest votes is eliminated, the voting continues, until a majority winner is determined. Typically the Games are awarded several years in advance, allowing the winning city time to prepare for the Games.In selecting the site of the Olympic Games, the IOC considers a number of factors, and chiefly among them is which organizing committee seems most likely to stage the Gameseffectively. The IOC also considers which parts of the world have not yet hosted the Games. For instance, Tokyo, the host of the 1964 Summer Games, and Beijing, that of the 2008 Games, were chosen in part to popularize the Olympic movement in Asia. Because of growing importance television worldwide, the IOC in recent years has also taken into account the host city's time zone. Whenever the Games take place in the USA or Canada, for example, American television networks are willing to pay specially higher amounts for television rights because they can broadcast popular events live in the best viewing hours.Once the Games have been awarded, it is the duty of the local organizing committee----not the IOC or the NOC of the host city's country to provide them with money. This is often done with a part of the Olympic television revenues, and corporate sponsorships, tickets sales, and other smaller revenue sources. In many cases there is also direct government support.Although many cities have achieved amounts of money by hosting the Games, the Olympics can be financially risky. When the financial gains from the Games were less than expected, the city was left with large debts.1. During voting, the city ______ will win host of Olympics.A. getting most votes in the first voteB. getting more than half votesC. being supported by a major cityD. going around successfully2. In selecting the host city, the IOC will consider several factors EXCEPT________ .A. the time zone of the host cityB. the existing facilities of the host cityC. whether the area has hosted the GamesD. whether profit could be made by the host city3. According to the passage, one of the reasons for Tokyo to be the host of Olympics in 1964 may be _______.A. it’s a major city of JapanB. it’s a famous cityC. it’s a city in AsiaD. it’s nice and cool in summer4. Every Olympic Games is financed by ________.A. the local government and the financial organizationsB. the local government and the organizing committeeC. the IOC and the National Olympic CommitteeD. the local companies and the local media5. The underlined phrase “financial gains” in the last sentence most probably means “__________”.A. sponsorshipB. reputationC. financial supportD. financial profitCIn Japan many workers for large corporations have a guarantee of lifetime employment. They will not be laid off during recessions (经济萧条) or when the tasks they perform are taken over by robots. To some observers, this is capitalism at its best, because workers are treated as people not things. Others see it as necessarily inefficient and believe it cannot continue if Japan is to remain competitive with foreign corporations more concerned about profits and less concerned about people.Defenders of the system argue that those who call it inefficient do not understand how it really works. In the first place not every Japanese worker has the guarantee of a lifetime job. The lifetime employment system includes only "regular employees." Many employees do not fall into this category, including all women. All businesses have many part time and temporary employees. These workers are hired and laid off during the course of the business cycle just as employees in the United States are. These "irregular workers" make up about 10 percent of the nonagricultural work force. Additionally, Japanese firms maintain some flexibility through the extensive use of subcontractors (分包单位). This practice is much more common in Japan than in the United States.The use of both subcontractors and temporary workers has increased markedly in Japan since the 1974-1975 recession. All this leads some people to argue that the Japanese system really is not all that different from the American system. During recessions Japanese corporations lay off temporary workers and give less business to subcontractors. In the United States, corporations lay off those workers with the least working experience. The difference then is probably less than the term "lifetime employment" suggests, but there still is a difference. And this difference cannot be understood without looking at the values of Japanese society. The relationship between employer and employee cannot be explained in purely contractual terms. Firms hold on to the employees and that employees stay with one firm. There are also practical reasons for not jumping from job to job. Most retirement benefits come from the employer. Changing jobs means losing these benefits. Also, teamwork is an essential part of Japanese production. Moving to a new firm means adapting to a different team and at least temporarily, lower productivity and lower pay.1. According to the passage, a woman in Japan________.A. cannot get a lifetime jobB. is impossible to get a part time jobC. will be employed for lifeD. is among the regular workers2. Which of the following is NOT the reason why Japanese workers stay with one firm?A. they don't want to lose their retirement benefits.B. they are not adaptable people.C. any change of jobs will make them less paid.D. they get used to the teamwork.3. It can be inferred from the passage that________.A. those who want to change jobs frequently in Japan should think twiceB. those who are first laid off by American corporations are temporary workersC. the use of subcontractors makes Japanese firms less flexibleD. the Japanese system is totally different from the American system4 What does the passage mainly discuss?A.

British doctors suggested last week and ran straight into a storm. The four researchers at Bristol University in western England were accused of weakening years of campaigning to warn people of the dangers of too much sun. Experts agree exposure to the sun’s ultraviolet rays (紫外线) increases the risk of skin cancer and accelerates the signs of aging. But in the British Medi cal Journal, the Bristol team led by Andrew Ness wrote, “There is evidence that the potential benefits of exposure to sunlight may outweigh the widely publicized negative effects on the incidence of skin cancer.”Vitamin D, made in the body in reaction to sunlight, prevented rickets (软骨病) in children and was associated with a protective effect against heart disease.Sunshine was also useful for treating certain skin conditions and there was evidence that it reduced the incidence of multiple sclerosis (硬化症). There was also the “feel good effect of lying or sitting in the sun.” The researchers said it was too early to advise people to spend more time in the sun, but suggested the basis of the current advice to cover up should be reviewed.“Perhaps, while we await the conclusions of such formal analyses, those of us who enjoy spending time in the sun can rest assured that the chance that we will be one of the people dying from the sun is small.” they added.Their article was strongly criticized by health campaigners who claimed it was unbalanced and not backed by scientific evidence. Britain’s Health Education Authority said skin cancer was the most common form of cancer in the country, with more than 50,000 new cases diagnosed each year and more than 2,000 people dying from the disease. It said treatment almost always required surgery and almost 50 per cent of cases were fatal. The authority’s skin cancer campaign manager Christopher New said, “We are very disappointed with this controversia l article. It doesn’t have enough supporting evidence and runs the risk of undoing many years of good health education.”1.

Often __1__ to as TCKs (Third Culture Kids) or Global Nomads, these students have a(n) __2__ impact on the global community.So who are these Third Culture Kids? They are not a new phenomenon. As one looks back on history, there is a realization that certain groups of people have led highly mobile lives, a key factor in describing TCKs. They often __3__ their parents into another country and spend a significant part of his or her development years outside the parents' culture. They are __4__ to new cultures and to other people in thecommunity who also move constantly. Their numbers __5_ into the hundreds of thousands an increasing. Easeof travel and constant relocation of people through multinational companies and global business links contribute to this __6__.The question “Who am I?” is frequently asked by TCKs. They have had a good number of cultural identities, and have built relationships to all the cultures, __7__ not having full ownership of any. Although elements from each culture are absorbed into TCK's life experience, the sense of __8__ is in relationship to others ofa similar background.As you enter into the world of TCKs, one might suspect they are no different. But it is clear, after spending only a short time with them, that they bring a deep knowledge from inside and a special ability to compare international and local issues. They represent many countries and cultures. They are the future cross-culturalists and hopefully future politicians, diplomats, government employees and educators.They certainly experience a different lifestyle compared to their mono-cultural peers but we can benefit from their global and __9__ lives. So, whatever one chooses to label the international students as ---TCKs, Global Nomads, or Global Souls ---we will gain unbelievable __10__.1. A. referring B. regarded C. described D. referred2.

I just sat still and didn't say anything.2.When Kristi was old enough, we sent her to a kindergarten. It would have been comforting to cry the day I left her in that room full ofkids. Kristi had spent hour upon hour playing by herself, but this moment, when she was the “different” child among them, she was probably the loneliest.3.However, positive things began to happen to Kristi in her school, and to her schoolmates, too. Kristi's classmates always took pains to praise her: “Kristi got all her spelling words right today.” No one bothered to add that her spelling list was easier than anyone else's.ter, she faced a very special challenge. The final event of the term was a program based on a final outcome of the year's music and physical education activities. Kristi was behind in both. My husband and I dreaded the day as well.5.On the day of the program, Kristi pretended to be sick. Desperately I wanted to keep her home. Surely missing one program couldn't matter. But my conscience wouldn't let me off that easily. So I practically got a pale, reluctant Kristi onto the school bus.6.Just as I had forced my daughter to go to school, now I forced myself to go to the program. At the kindergarten,I felt worried because ofher slow and clumsy reactions, she would surely hold up her team.7.The performance went well until it was time for the sack race. Surely Kristi would find it tough. Now each child had to climb into a sack, hop to a goal line, return and climb out of the sack. I noticed Kristi standing near the end of her line of players.8.But as her turn to join, a change took place in her team. The tallest boy behind Kristi placed his 1 on her waist. Two other boys stood ahead of her The moment the player in front of Kristi stepped from thesack, those two boys grabbed the sack and held it open while the tall boy lifted Kristi and dropped her into it. A girl ahead took her hand and supported her. Kristi gained her balance. Then off she hopped, smiling and proud.9.At the cheers of teachers, schoolmates and parents, I silently thanked the warm, understanding people in life who make it possible for my disabled daughter to be like her fellow human beings. Then I finally cried.1.When sending her daughter to the kindergarten, the writer must have felt .A.lonelyB. cheerfulC. worriedD. scared2.What does the underlined sentence imply?A.It didn't matter to miss one program because it was not important.B.It gave the author a good excuse not to send Kristi to the program.C.Kristi's illness prevented her from taking part in the program.D.The teachers wouldn't blame Kristi for she was ill.3.What does Paragraph 6 & 7 mainly tell us?A.The writer was worried about her daughter's performance.B.The sack race is very difficult for the kids at the kindergarten.C.The writer was unwilling to go to watch the program.D.All the kids performed well in the games except the sack race.4.The author expressed her gratitude mainly because .A.her daughter Kristi won the competition with the help ofher teammatesB.her daughter's teammates helped her experience the happy feeling of her ageC.the teachers at the kindergarten arranged some teammates to help her daughterD.the other kids' parents cheered for her daughter's good performance5.What's the best title of the passage?A. The day I criedB. An unforgettable experienceC.My disabled daughterD. A warm-hearted teamwork(B)Books, Films and PlaysThe novelist's medium is the written word, on might almost say the printed word. Typically the novel is consumed by a silent, individual reader, who may be anywhere at the time. The paperback novel is still the cheapest, most portable and adaptable form of narrative entertainment. It is limited to a single channel of information—writing. The narrative can go, effortlessly, anywhere: into space, people's head, palaces, prisons and pyramids, without any consideration of cost or practical possibility. In determining the shape and content of his narrative, the writer is restricted by nothing except purely artistic criteria. The novelist keeps absolute control over his text until it is published and received by the audience. He may be advised by his editor to revise his text, but if the writer refused to meet this condition no one would be surprised. It is not unknown for a well-established novelist to deliver his or her manuscript and expect the publisher to print it exactly as written.However, not even the most well-established playwright or screenplay writer would submit a script and expect it to be performed without any rewriting. This is because plays and motion pictures are cooperative forms of narrative, using more than one channel of communication.The production of a stage play involves, as well as the words of the author, the physical presence of the actors, their voices and gestures, the “set” and possibly music. Although the script is the essential basis of both stage play and film, it is a basis for subsequent revision negotiated between the writer another creative people involved. They are given “approval” of the choice of director and actors and have the right to attend rehearsals(排演),during which period they may undertake more rewriting work. In the case of the screenplay, the writer may have little or no control over the final form of his work. Contracts for the production of plays protect the rights of authors in this respect.In film or television work, on the other hand, the screenplay writer has no contractual right to this degree ofconsultation. While the script is going through its various drafts, the writer is in the driver's seat, although sometimes receiving criticism from the producer and the director. But once the production is under way, artistic control over the project tends to pass to the director This is a fact overlooked by most journalistic critics of television drama, who tend (unlike film critics) to give all the credit or blame for success or failure of a production to the writer and actors, ignoring the contribution, for good or ill, of the director6.Where might you find the passage?A. In a textbook.B. In a movie magazine.C. In a travelling brochure.D. In a shopping guide.7.Which ofthese subtitles would be most appropriate?A.Why does the future look good for writers of books, plays and films?B.What do audiences want from these three forms of entertainment?C.How do these forms of media compare for their producers?D.What benefit can we get from these forms ofmedia?8.Why can the novelist expect the publisher to print the manuscript exactly as written?A.Because the novelist keeps absolute control over his text.B.Because the paperback novel is most portable and adaptable.C.Because the novel is limited to a single channel of information一writing.D.Because the novelist is seldom advised by editors to revise the text.9.Which of the following statements is True according to the passage?A.Playwrights envy the simplicity of the novelist's work.B.Experience in the theatre improves the work of screenplay writers.C.Screenplay writers have the final say in how a TV drama will turn out.D.Playwrights are frequently involved in revising their work.10.What can be implied from the last sentence ofthe passage? critics often blame the wrong people for the failure of a program.B.The director is a determining factor in the future of a television drama.C.Few people know the screenplay writer is often criticized by the director.D.It is urgent for the film critics to realize their mistakes.(C)Shelly Ann Francis Pryce was just an average high school athlete. There was every indication that she was just another American teenager without much of a future. However, on person wants to change this. Stephen Francisobserved then eighteen-year-old Shelly Ann at a track meet and was convinced that he had seen the beginning of true greatness. Her time were not exactly impressive, but even so, he seemed there was something trying to get out, something the other coaches had overlooked when they had assessed her and found her lacking. He decided to offer Shelly Ann a place in his very strict training seasons. Their cooperation quickly produced results, and a few years later at Jamaica's Olympic games in early 2008, Shelly Ann, who at that time only ranked number 70 in the world, beat Jamaica's unchallenged queen of the sprint.“Where did she come from?” asked an astonished sprinting world, before concluding that she be one of those one-hit wonders that spring up from time to time, only to disappear again without signs.But Shelly Ann was to prove that she was anything but a one-hit wonder. At the Beijing Olympic she swept away any doubts about her ability to perform consistently by becoming the first Jamaican woman ever to win the 100 meters Olympic gold. She did it again at the World Championship in Britain, becoming the world champion with a time of 10.73 - the fourth record ever.Shelly-Ann is a little woman with a big smile. She has a mental toughness that did not come about by chance. Her journey to becoming the fastest woman on earth has been anything but smooth and effortless. She grew up in one of Jamaica's toughest inner-city communities known as Waterhouse, where she lived in a one-room apartment, sleeping four in a bed with her mother and two brothers. Waterhouse, one ofthe poorest communities in Jamaica, is a really violent and overpopulated place. Several of Shelly-Ann's friends and family were caught up in the killings; one of her cousins was shot dead, only a few streets away from where she lived. Sometimes her family didn't have enough to eat. She ran at the school championships barefooted because she couldn't afford shoes. Her mother Maxime, one of a family of fourteen, had been an athlete herself as a young girl but, like so many other girls in Waterhouse, had to stop after she had her first baby. Maxime's early entry into the adult world with its responsibilities gave her the determination to ensure that her kids would not end up in Waterhouse's roundabout of poverty. One of the first things Maxime used to do with Shelly-Ann was taking her to the track, and she was ready to sacrifice everything.It didn't take long for Shelly-Ann to realize that sports could be her way out of Waterhouse. On a summer evening in Beijing in 2008, all those long, hard hours of work and commitment finally bore fruit. The barefoot kid who, just a few years previously, had been living in poverty, surrounded by criminals and violence, had written a new chapter in the history of sports.But Shelly-Ann's victory was far greater than that. The night she won Olympic gold in Beijing, the routine murders in Waterhouse and the drug wars in the neighbouring streets stopped. The dark cloud above one of the world's toughest criminal neighbourhoods simply disappeared for a few days. “I have so much fire burning for mycountry,”Shelly said. She plans to start a foundation for homeless children and wants to build a community centre in Waterhouse. She hopes to inspire the Jamaicans to lay down their weapons. She intends to fight to make it a woman's as well as a man's world.As Muhammad Ali puts it, “Champions aren't made in gyms. Champions are made from something they have deep inside them. A desire, a dream, a vision.” One of the things Shelly-Ann can be proud of is her understanding of this truth.11.Why did Stephen Francis decide to coach Shelly-Ann?A.He had a strong desire to free her family from trouble.B.He sensed a great potential in her despite her weaknesses.C.She had big problems maintaining her performance.D.She suffered a lot of defeats at the previous track meets.12.What did the sprinting world think of Shelly-Ann before the 2008 Olympic Games?A.She would become a promising star.B.She badly needed to set higher goals.C.Her sprinting career would not last long.D.Her talent for sprinting was known to all.13.What can we infer from Shelly-Ann's statement underlined in Paragraph 5?A.She was highly rewarded forher efforts.B.She was eager to do more for her country.C.She became an athletic star in her country.D.She was the envy of the whole community.14.By mentioning Muhammad Ali's words, the author intends to tell us that .A. players should be highly inspired by coachesB.great athletes need to concentrate on patienceC.hard work is necessary in one's achievementsD.motivation allows great athletes to be on the top15.What is the best title for the passage?A.The Making of a Great AthleteB.The Dream for ChampionshipC.The Key to High PerformanceD.The Power of Full ResponsibilityPart 2I.Fill in the blanks with proper words. The first letter is given.Since 1960, considerable scientific researches have been done on chimps in their natural habitats. A__1__, scientists have found out that the social behaviors of Chimps are very similar to humans. Chimps will cooperate in certain ways, like gathering in war parties to protect their t__2__. But beyond the minimum requirements as social beings, they have little instinct to help one another. Chimps in the wild seek food for themselves. Even chimp mothers regularly decline to share food with their child ren. Who are able from a young age to gather their own food?In the laboratory, chimps don't naturally share food either. If a chimp is put in a cage w__3 __ he can pull in one plate of food for himself or, with no greater effort, a plate that also provi des food for a neighbor to the next cage, he will pull at random---he just doesn't care whether his neighbor gets fed or not. Chimps are truly selfish.Human children, on the other hand, are extremely c__4__. From the earliest ages, they decide to help others, to share information and to participate in a__5__ common goals. The psychologist Michael Tomasello has studied this cooperation in a series of experiments with very young children. He finds that if babies aged 18 months see a worried adult with hands full t__6__ to open a door, almost all will immediately try to help.There are several reasons to believe that the urges to help, inform and share are not taught, but n__7__ processed in young children. One is that these instincts appear at a very young age before most parents have started to train their children to behave socially. Another is that the helping behavior s are not improved if the children are rewarded. A third reason is that social intelligence develops in children before their general cognitive(认知的) skills, at least when c__8__ with chimps. In tests led by Tomasello, the human children did no better than the chimps on the physical world tests but were considerably better at understanding the s__9__ world.The core of what children's minds have and chimps' don't is what Tomasello calls shared intentionality. Part of this ability is that they can infer what others know or are thinking. But beyond that, even very young children want to be part of a shared purpose. They actively seek to be part of a “we”, a group that i__10__ to work toward a shared goal.II. Fill in the blanks with the given words in their proper forms.What do you do when you feel sad?Jack Ma went to see a film, one he claimed he had watched about 10 times. “My hero is Forrest Gump. Everytime I feel a sense of __1__. I watch the movie,” he said on CNBC on Sept 19. “I watched the movie before I came here to New York.”There Ma witnessed the Alibaba Group opening on the New York stock exchange with the largest initial public offering (IPO 新股发行) in American history.Alibaba, “the world's largest Internet commerce company”, according to The New York Times, “put China on an equal level with the US in the rapidly increasing global competition for technological innovation and __2__ transformation,” commented the South China Morning Post.It has also made Ma China's richest man with a fortune of around $25 billion (153 billion yuan), reported Reuter.Ma's rags-to-riches journey is just as __3__ as his Internet empire. Ma failed the national college entrance exams twice before he finally enrolled in Hangzhou Normal University on his third attempt. He studied English. After graduation, Ma became an English teacher for years after he failed to land jobs at a local KFC, a hotel, and the city police, reported USA Today.“Mr. Ma is a big believer in __4__,” commented The Wall Street Journal, also talking about Ma's English studying experience. Starting at the age of 12, Ma said he woke up at 5 am to walk or cycle to Hangzhou's main hotel so he could practice his English with foreign tourists. He did this for nine years and acted as a free tour guide to many.However, it was his vision and goals that launched his career. During a short trip to the US as an interpreter in 1995, Ma first experienced the Internet. He believed in the Internet's business potential when few other Chinese people did. He started Alibaba in his Hangzhou apartment, with 17 friends and $60,000 of funds. At the time, when e-commerce was unheard of in China, “I called myself a blind man riding on the back of blind tigers,” he once said. His unusual ideas earned him the nickname “Crazy Jack Ma”and Chinese media used words like “__5__”and “paranoid(妄想狂的)”to describe him.Indeed, Ma is different. Although he is very thin and about 160cm tall, “Ma is yet animated and forceful, with a bulging forehead and __6__, restless hands,” said The Guardian. “He is funny, creative, and a__7__ speaker.

own sub-culture.Often__41__to as TCKs(Third Culture Kids)or Global Nomads, these students have a(n)__42__impact on the global community.So who are these Third Culture Kids?They are not a new phenomenon.As one looks back on history, there is a realization that certain groups of people have led highly mobile lives,a key factor in describing TCKs.They often__43__their parents into another country and spend a significant part of his or her development years outside the parents’culture.They are__44__to new cultures and to other people in thecommunity who also move constantly.Their numbers__45__into the hundreds of thousands and are increasing.Ease of travel and constant relocation of people through multinational companies and global business links contribute to this__46__.The question“Who am I?”is frequently asked by TCKs.They have had a good number of cultural identities,and have built relationships to all the cultures,__47__not having full ownership of any. Although elements from each culture are absorbed into TCK’s life experience,the sense of__48__is in relationship to others of a similar background.As you enter into the world of TCKs,one might suspect they are no different.But it is clear,after spending only a short time with them,that they bring a deep knowledge from inside and a special ability to compare international and local issues.They represent many countries and cultures.They are the future cross-culturalists and hopefully future politicians,diplomats,government employees and educators.They certainly experience a different lifestyle compared to their mono-cultural peers but we can benefit from their global and__49__lives.So,whatever one chooses to label the international students as ---TCKs,Global Nomads,or Global Souls---we will gain unbelievable__50__.41.

Surely missing one program couldn’t matter.But my conscience wouldn’t let me off that easily.So I practically got a pale,reluctant Kristi onto the school bus.6.Just as I had forced my daughter to go to school,now I forced myself to go to the program.At the kindergarten,I felt worried because of her slow and clumsy reactions,she would surely hold up her team.7.The performance went well until it was time for the sack race.Surely Kristi would find it tough.Now each child had to climb into a sack,hop to a goal line,return and climb out of the sack.I noticed Kristi standing near the end of her line of players.8.But as her turn to join,a change took place in her team.The tallest boy behind Kristi placed his hands on her waist.Two other boys stood ahead of her.The moment the player in front of Kristi stepped from the sack,those two boys grabbed the sack and held it open while the tall boy lifted Kristi and dropped her into it.A girl ahead took her hand and supported her.Kristi gained her balance.Then off she hopped,smiling and proud.9.At the cheers of teachers,schoolmates and parents,I silently thanked the warm,understanding people in life who make it possible for my disabled daughter to be like her fellow human beings.Then I finally cried.51.When sending her daughter to the kindergarten,the writer must have felt________.A.lonelyB.cheerfulC.worriedD.scared52.What does the underlined sentence imply?A.It didn’t matter to miss one program because it was not important.B.It gave the author a good excuse not to send Kristi to the program.C.Kristi’s illness prevented her from taking part in the program.D.The teachers wouldn’t blame Kristi for she was ill.53.What does Paragraph6&7mainly tell us?A.The writer was worried about her daughter’s performance.B.The sack race is very difficult for the kids at the kindergarten.C.The writer was unwilling to go to watch the program.D.All the kids performed well in the games except the sack race.54.The author expressed her gratitude mainly because________.A.her daughter Kristi won the competition with the help of her teammatesB.her daughter’s teammates helped her experience the happy feeling of her ageC.the teachers at the kindergarten arranged some teammates to help her daughterD.the other kids’parents cheered for her daughter’s good performance55.What’s the best title of the passage?A.The day I criedB.An unforgettable experienceC.My disabled daughterD.A warm-hearted teamwork(B)Books,Films and PlaysThe novelist’s medium is the written word,on might almost say the printed word.Typically the novel is consumed by a silent,individual reader,who may be anywhere at the time.The paperback novel is still the cheapest,most portable and adaptable form of narrative entertainment.It is limited to a single channel of information—writing.The narrative can go,effortlessly,anywhere:into space,people’s head,palaces, prisons and pyramids,without any consideration of cost or practical possibility.In determining the shape and content of his narrative,the writer is restricted by nothing except purely artistic criteria.The novelist keeps absolute control over his text until it is published and received by the audience.He may be advised by his editor to revise his text,but if the writer refused to meet this condition no one would be surprised.It is not unknown for a well-established novelist to deliver his or her manuscript and expect the publisher to print it exactly as written.However,not even the most well-established playwright or screenplay writer would submit a script and expect it to be performed without any rewriting.This is because plays and motion pictures are cooperative forms of narrative,using more than one channel of communication.The production of a stage play involves,as well as the words of the author,the physical presence of the actors,their voices and gestures,the“set”and possibly music.Although the script is the essential basisof both stage play and film,it is a basis for subsequent revision negotiated between the writer and the other creative people involved.They are given“approval”of the choice of director and actors and have the right to attend rehearsals(排演),during which period they may undertake more rewriting work.In the case of the screenplay,the writer may have little or no control over the final form of his work.Contracts for the production of plays protect the rights of authors in this respect.In film or television work,on the other hand,the screenplay writer has no contractual right to this degree of consultation.While the script is going through its various drafts,the writer is in the driver’s seat, although sometimes receiving criticism from the producer and the director.But once the production is under way,artistic control over the project tends to pass to the director.This is a fact overlooked by most journalistic critics of television drama,who tend(unlike film critics)to give all the credit or blame for success or failure of a production to the writer and actors,ignoring the contribution,for good or ill,of the director.56.Where might you find the passage?A.In a textbook.B.In a movie magazine.C.In a travelling brochure.D.In a shopping guide.57.Which of these subtitles would be most appropriate?A.Why does the future look good for writers of books,plays and films?B.What do audiences want from these three forms of entertainment?C.How do these forms of media compare for their producers?D.What benefit can we get from these forms of media?58.Why can the novelist expect the publisher to print the manuscript exactly as written?A.Because the novelist keeps absolute control over his text.B.Because the paperback novel is most portable and adaptable.C.Because the novel is limited to a single channel of information—writing.D.Because the novelist is seldom advised by editors to revise the text.59.Which of the following statements is True according to the passage?A.Playwrights envy the simplicity of the novelist’s work.B.Experience in the theatre improves the work of screenplay writers.C.Screenplay writers have the final say in how a TV drama will turn out.D.Playwrights are frequently involved in revising their work.60.What can be implied from the last sentence of the passage? critics often blame the wrong people for the failure of a program.B.The director is a determining factor in the future of a television drama.C.Few people know the screenplay writer is often criticized by the director.D.It is urgent for the film critics to realize their mistakes.(C)Shelly Ann Francis Pryce was just an average high school athlete.There was every indication that she was just another American teenager without much of a future.However,on person wants to change this. Stephen Francis observed then eighteen-year-old Shelly Ann at a track meet and was convinced that he had seen the beginning of true greatness.Her time were not exactly impressive,but even so,he seemed there was something trying to get out,something the other coaches had overlooked when they had assessed her and found her lacking.He decided to offer Shelly Ann a place in his very strict training seasons.Their cooperation quickly produced results,and a few years later at Jamaica’s Olympic games in early2008,Shelly Ann,who at that time only ranked number70in the world,beat Jamaica’s unchallenged queen of the sprint.“Where did she come from?”asked an astonished sprinting world,before concluding that she must be one of those one-hit wonders that spring up from time to time,only to disappear again without signs. But Shelly Ann was to prove that she was anything but a one-hit wonder.At the Beijing Olympic she swept away any doubts about her ability to perform consistently by becoming the first Jamaican woman ever to win the100meters Olympic gold.She did it again at the World Championship in Britain, becoming the world champion with a time of10.73–the fourth record ever.Shelly-Ann is a little woman with a big smile.She has a mental toughness that did not come about by chance.Her journey to becoming the fastest woman on earth has been anything but smooth and effortless. She grew up in one of Jamaica’s toughest inner-city communities known as Waterhouse,where she lived in a one-room apartment,sleeping four in a bed with her mother and two brothers.Waterhouse,one of the poorest communities in Jamaica,is a really violent and overpopulated place.Several of Shelly-Ann’s friends and family were caught up in the killings;one of her cousins was shot dead,only a few streets away from where she lived.Sometimes her family didn’t have enough to eat.She ran at the school championships barefooted because she couldn’t afford shoes.Her mother Maxime,one of a family of fourteen,had been an athlete herself as a young girl but,like so many other girls in Waterhouse,had to stop after she had her first baby.Maxime’s early entry into the adult world with its responsibilities gave her the determination to ensure that her kids would not end up in Waterhouse’s roundabout of poverty. One of the first things Maxime used to do with Shelly-Ann was taking her to the track,and she was ready to sacrifice everything.It didn’t take long for Shelly-Ann to realize that sports could be her way out of Waterhouse.On a summer evening in Beijing in2008,all those long,hard hours of work and commitment finally bore fruit. The barefoot kid who,just a few years previously,had been living in poverty,surrounded by criminals and violence,had written a new chapter in the history of sports.But Shelly-Ann’s victory was far greater than that.The night she won Olympic gold in Beijing,the routine murders in Waterhouse and the drug wars in the neighbouring streets stopped.The dark cloud above one of the world’s toughest criminal neighbourhoods simply disappeared for a few days.“I have so much fire burning for my country,”Shelly said.She plans to start a foundation for homeless children and wants to build a community centre in Waterhouse.She hopes to inspire the Jamaicans to lay down their weapons.She intends to fight to make it a woman’s as well as a man’s world.As Muhammad Ali puts it,“Champions aren’t made in gyms.Champions are made from something they have deep inside them.A desire,a dream,a vision.”One of the things Shelly-Ann can be proud of is her understanding of this truth.61.Why did Stephen Francis decide to coach Shelly-Ann?A.He had a strong desire to free her family from trouble.B.He sensed a great potential in her despite her weaknesses.C.She had big problems maintaining her performance.D.She suffered a lot of defeats at the previous track meets.62.What did the sprinting world think of Shelly-Ann before the2008Olympic Games?A.She would become a promising star.B.She badly needed to set higher goals.C.Her sprinting career would not last long.D.Her talent for sprinting was known to all.63.What can we infer from Shelly-Ann’s statement underlined in Paragraph5?A.She was highly rewarded for her efforts.B.She was eager to do more for her country.C.She became an athletic star in her country.D.She was the envy of the whole community.64.By mentioning Muhammad Ali’s words,the author intends to tell us that_________.A.players should be highly inspired by coachesB.great athletes need to concentrate on patienceC.hard work is necessary in one’s achievementsD.motivation allows great athletes to be on the top65.What is the best title for the passage?A.The Making of a Great AthleteB.The Dream for ChampionshipC.The Key to High PerformanceD.The Power of Full ResponsibilityPaper TwoI.Fill in the blanks with proper words.The first letter is given.Since1960,considerable scientific researches have been done on chimps in their natural habitats. A__1__,scientists have found out that the social behaviors of Chimps are very similar to humans.Chimps will coo perate in certain ways,like gathering in war parties to protect their t__2__.But beyond the mini mum requirements as social beings,they have little instinct to help one another.Chimps in the w ild seek food for themselves.Even chimp mothers regularly decline to share food with their child ren.Who are able from a young age to gather their own food?In the laboratory,chimps don’t naturally share food either.If a chimp is put in a cage w__3 __he can pull in one plate of food for himself or,with no greater effort,a plate that also provi des food for a neighbor to the next cage,he will pull at random--he just doesn’t care whether his neighbor gets fed or not.Chimps are truly selfish.Human children,on the other hand,are extremely c__4__.From the earliest ages,they decide to help others,to share informati on and to participate in a__5__common goals.The psychologist Michael Tomasello has studied t his cooperation in a series of experiments with very young children.He finds that if babies aged 18months see a worried adult with hands full t__6__to open a door,almost all will immediate ly try to help.There are several reasons to believe that the urges to help,inform and share are not taught, but n__7__processed in young children.One is that these instincts appear at a very young age before most parents have started to train their children to behave socially.Another is that the helping behavior s are not improved if the children are rewarded.A third reason is that social intelligence develop s in children before their general cognitive(认知的)skills,at least when c__8__with chimps.In tests led by Tomasello,the human children did no better than the chimps on the physical world tests but were considerably better at understandi ng the s__9__world.The core of what children’s minds have and chimps’°don’t is what Tomasello calls shared in tentionality.Part of this ability is that they can infer what others know or are thinking.But beyo nd that,even very young children want to be part of a shared purpose.They actively seek to be part of a we”,a group that

do you do when you feel sad?Jack Ma went to see a film,one he claimed he had watched about10times.“My hero is Forrest Gump.Every time I feel a sense of__1__.I watch the movie,”he said on CNBC on Sept19.“I watched the movie before I came here to New York.”There Ma witnessed the Alibaba Group opening on the New York stock exchange with the largest initial public offering(IPO新股发行)in American history.Alibaba,“the world’s largest Internet commerce company”,according to The New York Times,“put China on an equal level with the US in the rapidly increasing global competition for technological

rags-to-riches journey is just as__3__as his Internet empire.Ma failed the national college entrance exams twice before he finally enrolled in Hangzhou Normal University on his third attempt.He studied English.After graduation,Ma became an English teacher for years after he failed to land jobs at a local KFC,a hotel,and the city police,reported USA Today.“Mr.Ma is a big believer in__4__,”commented The Wall Street Journal,also talking about Ma’s English studying experience.Starting at the age of12,Ma said he woke up at5am to walk or cycle to Hangzhou’s main hotel so he could practice his English with foreign tourists.He did this for nine years and acted as a free tour guide to many.However,it was his vision and goals that launched his career.During a short trip to the US as an interpreter in1995,Ma first experienced the Internet.He believed in the Internet’s business potential when few other Chinese people did.He started Alibaba in his Hangzhou apartment,with17friends and$60,000 of funds.At the time,when e-commerce was unheard of in China,“I called myself a blind man riding on the back of blind tigers,”he once said.His unusual ideas earned him the nickname“Crazy Jack Ma”and Chinese media used words like“__5__”and“paranoid(妄想狂的)”to describe him.Indeed,Ma is different.Although he is very thin and about160cm tall,“Ma is yet animated and forceful,with a bulging forehead and__6__,restless hands,”said The Guardian.“He is funny,creative, and a__7__speaker.I often thought he has another career in stand-up comedy,”Duncan Clark,a Brit who is a Beijing-based

Since its creation,the program,which is mainly conducted after school,has spread to more than850 schools across the country.It has gotten a big push from the Canent craze among adolescents for comic book clubs and for Manga,a wildly popular variety of comic originating in Japan.The point is not to drop a comic book on a child’s desk and say:“read this”.Rather,the workshops give groups of students the opportunity to collaborate on often complex stories and characters that they then revise,publish and share with others in their communities.Teachers are finding it easier to teach writing,grammar and punctuation with material that students are fully invested in.And it turns out that comic books have other built-in advantages.The pairing of visual and written plotlines that they rely on appear to be especially helpful to struggling readers.No one is suggesting that comic books should substitute for traditional books or for standard reading and composition lessons.Teachers who would once have dismissed comics out of hand are learning to exploita style that clearly has a powerful hold on young minds.They are using what works.51.Which of the following is probably the best title of the passage?A.Japanese Comic Books./doc/4022906b58cfa1c7aa00b52acfc789eb172d9ed0.html ic Books in the Classroom.C.Reading Efficiently.D.A Current Craze.52.Which of the following is TRUE according to the passage?A.Students’reading materials are often involved with their daily life./doc/4022906b58cfa1c7aa00b52acfc789eb172d9ed0.html ic books can now take the place of textbooks at school.C.Teachers now give away comic books for children to read.D.Children’s imagination plays a key role in comic books.53.The underlined phrase“its”in Paragraph2probably refers to______.A.the Comic Book Project’sB.an elementary school’sD.the country’s54.The main purpose of the Comic Book Project is to________.A.develop the cooperation among adolescentsB.make sure that students live a rich and colorful life after schoolC.help students who have some difficulty in readingD.popularize a new method of teaching55.It can be inferred that________./doc/4022906b58cfa1c7aa00b52acfc789eb172d9ed0.html ic books were first used in Japanese schoolsB.parents have different opinions about their children reading comic booksC.more and more teachers will realize the advantages of comic books/doc/4022906b58cfa1c7aa00b52acfc789eb172d9ed0.html ic books will be allowed to enter all the schools in the country(B)On her first morning in America last summer,my daughter went out to explore her new neighborhood alone,without even telling my wife or me.Of course we were worried;we had just moved from Berlin,and she was just8.But when she came home,we realized we had no reason to panic.Beaming with pride,she told us how she had discovered the little park around the corner,and had made friends with a few local dog owners.She had taken possession of her new environment,and was keen to teach us things we didn’t know.When this story comes up in conversations with American friends,we are usually met with polite disbelief.Most are horrified by the idea that their children might roam around without adult supervision. In Berlin,where we lived in the center of town,our girls would ride the Metro on their own–a no-no in Washington.Or they’d go alone to the playground or walk a mile to a piano lesson.Here in quiet and traffic-safe suburban Washington,they don’t even find other kids on the street to play with.On Halloween, when everybody was out to trick or treat,we were surprised by how many children actually lived here whom we had never seen.A study by the University of California has found that American kids spend90per cent of their leisure time at home,often in front of the TV or playing video games.Even when kids are physically active,they are watched closely by adults,either in school,at home,at afternoon activities or in the car, shuttling them from place to place.Such narrowing of children’s world has happened across the developed world.But German parents are generally much more accepting of letting children take some risks.To them,it seems that American’s middle class has taken overprotective parenting to a new level,with the government acting as a super nanny.But when it comes to their own children,the same respondents were terrified by the idea of givingthem only a little of the freedom they once enjoyed.Many cited fear of abduction,even though crime rates have declined significantly.The most recent in-depth study found that,in1999,only115children nationwide were victims of a“stereotypical kidnapping”by a stranger;the majority was abducted by a family member.The same year,2931children under15died as passengers in car accidents.Driving children around is statistically more dangerous than letting them roam freely.“We are depriving them of opportunities to learn how to take control of their own lives,”writes Peter Gray,a research professor at Boston College.He argues that this increases the chance that they will suffer from anxiety,depression,and various other mental disorders,which have gone up dramatically in recent decades.I am no psychologist like Professor Gray,but I know I won’t be around forever to protect my girls from the challenges life holds in store for them.And by giving kids more control over their lives,they learn to have more confidence in their own capabilities.56.Hearing the author’s daughter exploring the new neighborhood alone,his American friends feel ________.B.proudC.doubtfulD.terrified57.We can conclude from Paragraph3that________.A.American kids enjoy playing at homeB.German parents are less protective than American parentsC.German kids like taking risks more than American kidsD.American parents don’t limit their children’s activities in their leisure time58.In which of the following countries isn’t narrowing of the child’s world likely to happen?A.AmericaB.IndiaC.JapanD.England59.It’s implied from Professor Gray’s words that________.A.parents should always be around their children to protect them from risksB.more and more parents suffer from mental problemsC.children are having more opportunities to take control of their livesD.giving children more freedom is beneficial to their mental development60.Which of the following words can best describe the author’s parenting?A.Open-mined.B.Irresponsible.C.Careless.D.Protective.(C)Glaciers are large masses of ice on land that show evidence of past or present movement.They grow by the gradual transformation of snow into glacier ice.A fresh snowfall is a fluffy mass of loosely packed snowflakes,small delicate ice crystals grown in the atmosphere.As the snow ages on the ground for weeks or months,the crystals shrink and become more compact,and the whole mass becomes squeezed together into a more dense form,granular snow.As new snow falls and buries the older snow,the layers of granular snow further compact to form firm,a much denser kind of snow,usually a year or more old,which has little pore space.Further burial and slow cementation–a process by which crystals become held together in a mosaic of intergrown ice crystals–finally produce solid glacial ice.In this process of recrystallization,the growth of new crystals at the expense of old ones,the percentage of air is reduced from about90percent for snowflakes to less than20 percent for glacier ice.The whole process may take as little as a few years,but more likely ten or twenty years or longer.The snow is usually many meters deep by the time the lower layers are converted into ice.In cold glaciers those formed in the coldest regions of the Earth,the entire mass of ice is at temperatures below the melting point and no free water exists.In temperate glaciers,the ice is at the melting point at every pressure level within the glacier,and free water is present as small drops or aslarger accumulations in tunnels within or beneath the ice.Formation of a glacier is complete when ice has accumulated to a thickness(and thus weight) sufficient to make it move slowly under pressure,in much the same way that solid rock deep within the Earth can change shape without breaking.Once that point is reached,the ice flows downhill,either as a tongue of ice filling a valley or as thick ice cap that flows out in directions from the highest central area where the most snow accumulates.The trip down leads to the eventual melting of ice.61.Which of the following does the passage mainly discuss?A.The effect of glaciers on climate.B.Damage from glaciers.C.Glacier formation.D.The location of glaciers.62.Which of the following will cause density within the glacier to increase?A.Increased water and air content.B.Pressure from the weight of new snow.C.Long periods of darkness and temperature variations.D.Movement of the glacier.63.Which of the following will be lost if a glacier forms?A.AirB.PressureC.WeightD.Rocks64.What is the purpose of the material in paragraph3?A.To define two types of glaciers.B.To contrast glacier ice with non-glacier ice.C.To present theories of glacier formation.D.To discuss the similarities between glacial types.65.It can be inferred from the last paragraph that a glacier________.A.can revert to a fluffy massB.maintains the same shape throughout the glacial processC.is too cold to be thoroughly studiedD.can contribute water to lakes,rivers,or oceansPart TwoI.Fill in the blanks with proper words.The first letter is given.As more and more people speak the global languages of English,Chinese,Spanish,and Arabic,other languages are rapidly d__1__.In fact,half of the6,000-7,000languages spoken around the world today will likely die

realizing it.It is not the amazing complexity of television,nor the__1__technology of transport.The__2__wonder we share and experience is our ability to make noise without mouths,and so transmit ideas and thoughts to each other’s minds.This ability comes so__3__that we tend to forget what a miracle it is.Obviously,the ability to talk is something that marks humans off from animal.Of course,some animals have powers just as amazing.Birds can fly thousands miles by__4__positions of the stars in the sky in__5__to the time of day and year.In Nature’s talent show,humans are a species of animal that have developed their own special act.If we reduce it to basic terms,it’s an ability for communicating information to others,by varying sounds we make as we breathe out.Not that we don’t have other powers of communication.Our facial__6__convey our emotions,such as anger,orjoy,or__7__.The way we hold our heads can indicate to others whether we are happy or sad. This is so-called“body language”.Bristling(直⽴的)fur is an unmistakable warning of attack among many animals.__8__,the bowed head or drooping tail shows a readiness to take second place in any animal gathering.Such a means of communication is a basic mechanism that animals,including human beings, instinctively(本能地)acquire and display.Is the ability to speak just another sort of instinct?If so,how did human beings acquire this amazing skills?__9__can readily indicate that particular area of our brain where speech mechanisms function,but this doesn’t tell us how that part of our bodies__10__in our biological history.III.Fill in the blanks with the proper form of each verb given.Four people in England back in1953,stared at Photo51.It wasn’t much—a picture__1__(show)a black X.But three of these people won the Nobel Prize for figuring out what the photo really showed—the shape of DNA.The discovery brought fame and fortune to scientists James Watson,Francis Crick,and Maurice Wilkins.The fourth,the one who actually made the picture,__2__(leave out).Her name was Rosalind Franklin.“She should have been up there,”says historian Mary Bowden.“If her photo__3__(not be)there,the others__4__(can’t come up)with the structure.”One reason Franklin was missing was that she__5__(die)of cancer four years before the Nobel decision.But now scholar doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitions.At Cambridge University in the1950s,Watson and Crick tried to make models by cutting up shapes of DNA’s parts and then putting them together.In the meantime,at King’s College in London,Franklin andWilkins shone X-rays at the molecule(分⼦).The rays produced patterns reflecting the shape.But Wilkins and Franklin’s relationship was a lot rockier than the celebrated teamwork of Watson and Crick.Wilkins thought Franklin was hired to be his assistant.But the college actually employed her__6__ (take over)the DNA project.What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out.And she was not shy about saying so.That angered Watson,who attacked her in return,。

And if the local fishermen spot such intelligent sea creatures in need, they will save them from danger without hesitation.In the recent rescue of melon-headed whales, they tried their best to help as a 37-second video of a young man sleeping in the water holding a whale soon went viral online, with netizens applauding his constant efforts and caring heart in trying to keep the whale alive. “The melon-headed whale knew I was trying to save it and would be more cooperative and wouldn’t move.” said Lu Wenhui, a 21-year-old diver from Hangzhou Changqiao Polar Ocean Park, who held up the whale’s head so it could breathe easily. Lu had been staying in the water for 10 hours by 4 a.m. Wednesday after coming for the rescue work on Tuesday, when the stranded whales were first spotted.“Whales are mammals and need to breathe in air — that’s why I had to hold its head, to ensure it could breathe smoothly the whole time,” Lu said. The stranded whales, after the struggling of being transported, were worn out when they arrived at the fish farm and might have drowned if they were left unattended.The reason why the whales were stranded is still not clear. And these stranded whales were returned to the ocean because they are not adapted to artificial breeding environments on land.4. What do local fishermen usually do after finding haizi in danger?A. Ignore them.B. Feed them.C. Transport them.D. Protect them.5. Why does the author describe Lu’s rescue work?A. To introduce the whales in detail.B. To voice his views on the diver.C. To praise the efforts made by rescuers.D. To explain the value of the whales.6. What can we say about the melon-headed whales according to the text?A. They are rarely seen by locals.B. They are used to breathing in the sea.C. They aren’t suited to artificial surroundings.D. They are fond of swimming near the seaside.7. Which of the following can be the best title for the text?A. Melon-headed Whales Were StrandedB. Rescuers Went All out to Help WhalesC. Fishermen Transported Stranded WhalesD. Witnesses Voiced Opinions on Rescue WorkCMy sister Alice and I have been trying to get people tostop dropping cigarette(香烟)butts(烟头)for seven years. One day, we were walking in our hometown and saw hundreds of cigarette butts on the ground. They made the town look so ugly that we decided to start a group to make people dropping butts. We called it “No Butts About It”.At first, we drew pictures with “The Earth is not your ashtray(烟灰缸)”written on them. We put the pictures around our hometown—in parks, by beaches, and along roads. We wanted to make people understand that dropping butts hurts the environment. Most smokers don’t think that dropping butts hurts the Earth. But it does, and all rubbish does!Later, we wrote to companies and asked them for money to help us. We used the money to buy ashtrays to give to smokers. We wanted smokers to carry the ashtrays with them so they didn’t have to drop butts.At the moment, we are trying to get cigarette companies to put an ashtray in each pack of cigarettes. Some companies want to do it. Many people have started to join our group since it began. Today there are 45 other “No Butts About It” groups inAmerica.Now there even groups inEngland,Australia, andIndia! Many newspapers have written about my sister and me over the last seven years. And we have won many prizes for what we do. But we are not interested in prizes. We just want to make the Earth a better and cleaner place for animals, plants and people.One day, it will be.8. What did the writer think about the cigarette butts in the first place?A. They made the town smelly.B. They made the town unhealthy.C. They made the town dirty.D. They made the town poor.9. What does the writer do with the cigarette butts?A. Give ashtrays to the smokers.B. Stop people buying cigarettes.C. Pick up the cigarette butts.D. Win prizes for starting groups.10. From the passage we can know that _____.A. no companies wanted to give money to themB. The writer believes that the Earth will be a better and cleaner placeC. There are only 45”No Butts About It”D. The writer likes to be on newspapers and win prizes211. Which is the best tittle for the passage?A. Save our Town From Cigarette Butts.B. Buy Yourself An Ashtray.C. Cigarette Butts Also Destroy Other Countries.D. No Butts Prize.DA 25-year-old American with a university degree can expect to livea decade longer than a peer who dropped out of high school. Although researchers have long known that the rich live longer than the poor, this education gap is less well documented. And although the average American’s expected span(预期寿命) has been smooth in recent year—and, shockingly, even fell between 2015 and 2017—that of the one-third with a bachelor’s degree has continued to lengthen.This gap in life expectancy is growing, according to new research published in the report of the National Academy of Sciences. Anne Case and Angus Deation ofPrincetonUniversityfound that the lifespans of those with and without a bachelor’s degree started to become different in the 1990s and 2000s. This gap grew even wider in the 2010s.What is the link between schooling and longevity(长寿)? Some argue that better-educated people develop healthier lifestyles: each additional year of study reduces the chances of being a smoker and of being overweight. The better-educated earn more, which in turn is associated with greaterhealth.Ms Case and Mr Deaton argue that changes in labor markets, including the rise of automation and increased demand for highly-educated workers, coupled with the rising costs of employer-provided health care, have decreased the supply of well-paid jobs for those without a degree. This may be contributing to higher rates of alcohol and drug use, suicide and other “deaths of despair”.The authors argued that the educational gap in mortality(致死率) will widenin the wake ofthe covid-19pandemic. ForAmerica’s overall life expectancy to start climbing again, improvements will be needed across all social groups, not just among the privileged few.12. When did the lifespans of people with and without a degree vary greatly?A. In the 1990s.B. In the 2020sC. In the 2000sD. In the 2010s13. According to the article, changes in labor markets reduce jobs for those without a degree. Which change is NOT included?A. The rising spending of employer-provided health care.B. The gap in life expectancy.C. Raised request for better-educated workers.D. The development of automation.14. What does the underlined phrase “in the wake of” probably mean ?A. afterB. untilC. beforeD. while15. What is the best title for the text?A. Changes in labor market.B. Quit bad habits by Further studyC. Educated Americans live longer.D. Highly-educated people develop healthier lifestyles.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
