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. I often thought he has another career in stand-up comedy,” Duncan Clark, a Brit who is a Beijing-based technology __8__, told USA Today.While Ma joked to The Wall Street Journal that he had “a unique and ugly face so people always recognize me”, it is “his readiness to make fun of himself, and speak his mind that is a contrast to China's often __9__ corporate leaders”, commented USA Today.Ma told Time magazine that he was “old for the Internet”. He started to slow down and looked around.According to The Wall Street Journal, Ma plans to open a tai chi club with the actor Jet Li, build an entrepreneurship university in Hangzhou and continue to work on several __10__ projects.III.Fill in the blanks with the given verbs in their proper forms.“Have you gotten married?” “Have you received a salary raise??” “Have you bought a house???” Are you familiar with these questions starting with “have you” and ending in at least one question mark?If your answer is yes and you are getting sick of answering these questions, you probably __1__ (become) a member of the “home-fear group”.The “home-fear group” refers to those feeling anxious about returning home during the Spring Festival. They have deep concerns about __2__ (go) back home for such factors as heavy economic pressure, high costs of the festival, the troubles of buying tickets, the long distance of the journey exposure of private matters __3_ (involve) family or love life.Now, a special song has been tailor-made for this group.The seven-minute song utilizes a choir style and rap. The beginning of the song __4__ (sing) by the choir, which involves a family scene where a recently returned young adult is asked a series of questions by family members. After the “question attack” from relatives, the young man decides __5__ (reflect) on his past and also defend himself through rap.According to the official microblog account of Shanghai Rainbow Indoor Chorus, this is more than just a funny song, but a useful guide for young people. A careful listen to some ofthe lyrics __6__ (inspire) you on how to wisely answer many 'Spring Festival-specific' questions.“It is a very interesting yet brainwashing song, truly __7__ (describe) the less satisfactory situation quite a few young Chinese people have been trapped in,” Sina Microblog user Santilin Clouds said.According to a survey recently __8__ (conduct) among 1,918 young people by the research center at China Youth Daily, an overwhelming 86.4 percent of interviewees think it is necessary that they __9__ (return) to their homeland during the Spring Festival, even if they are afraid of losing face for an average life or career.“We might not work hard in the future if we __10__ (be) that good.

大夫逄同谏曰：“今夫吴兵加齐、晋，怨深于楚﹑越，名高天下，实害周室，德少而功多，必淫自矜。

为越计，莫若结齐，亲楚，附晋，以厚吴。

吴之志广，必轻战。

是我连其权，三国伐之，越承其弊，可克也。

”勾践曰：“善。

”其后四年。

吴士民罢弊，轻锐尽死于齐﹑晋。

而越大破吴，因而留围之三年，吴师败，越遂复栖吴王于姑苏之山。

吴王使公孙雄肉袒膝行而前，请成越王曰：“孤臣夫差敢布腹心，异日尝得罪于会稽，夫差不敢逆命，得与君王成以归。

今君王举玉趾而诛孤臣，孤臣惟命是听，意者亦欲如会稽之赦孤臣之罪乎？”勾践不忍，欲许之。

范蠡曰：“会稽之事，天以越赐吴，吴不取。

今天以吴赐越，越其可逆天乎？且夫君王蚤朝晏罢，非为吴邪？谋之二十二年，一旦而弃之，可乎？且夫天与弗取，反受其咎。

君忘会稽之厄乎？”勾践曰：“吾欲听子言，吾不忍其使者。

”范蠡乃鼓进兵，曰：“王已属政于执事，使者去，不者且得罪。

”吴使者泣而去。

勾践怜之，乃使人谓吴王曰：“吾置王甬东，君百家。

”吴王谢曰：“吾老矣，不能事君王！”遂自杀。

Cloze (15%)Mt. Qomolangma was first conquered(征服) in 1953, when Sir Edmund Hillary and Sherpa Tenzing, his guide became the first climbers to reach the top. More than 750 times have people tried to conquer the mountain, but not ____41____ successful, yet every climber knows the ____42____. This doesn't stop teams of climbers arriving at the base camp every year with the courage of reaching the top.Two such climbers, and two ____43____ ones, are Scott Fischer and Rob Hall. Fischer, an American guide with much experience, was lost in a terrible storm which swept across the ____44____. A rescue team found him and his friend, but didn't ____45____ to bring Fischer to safety in the terrible conditions because he was dying. New Zealander Rob Hall, ____46____ experienced climber and guide, was lost near the top. These two men had something in common: they were both guides who took ‘tours’ of less experienced climbers up the mountain.There is a lot that can go wrong in an action to reach the top of Mt. Qomolangma: a ____47____ change in weather conditions or a wrong turning. Planes will only be sent to rescue if they ____48____ in advance. In spite of all these, there is a business in leading guided tours to the top. ____49____ mountain climbers can now pay $64,000 or more to achieve their aim.Many people wonder how guides can hope to ____50____their inexperienced climberswhen they fail to keep themselves alive.

Poverty, hard work, and even the fact that Father March was away with the Union armies could not down the spirits of Meg, Jo, Amy, and Marmee, as the March girls called their mother.[来源:/doc/f6b1c174fc0a79563c1ec5da50e25 24de418d010.html]The March sisters tried to be good but had their share of faults. Pretty Meg was often displeased with the schoolchildren she taught; boyish Jo was easy to become angry; golden-haired schoolgirl Amy liked to show up; but Beth, who kept the house, was loving and gentle always.The happy days passed and dar kness came when a telegram arrived for Mrs. March. “Your husband is very ill,” it said, “come at once.” The girl tried to be brave when their mother left for the front. They waited and prayed. Little Beth got scarlet fever when she was taking care of the sick neighbor. She became very ill but began to recover by the time Marmee was back. When Father came home from the front and at that joyful Christmas dinner they were once more all together.Three years later the March girls had grown into young womanhood. Meg became Mrs. Brooke, and after a few family troubles got used to her new state happily. Jo had found pleasure in her literary efforts. Amy had grown into a young lady with a talent for design and an even greater one for society. But Beth had never fully regained her health, and her family watched her with love and anxiety.Amy was asked to go and stay in Europe with a relative ofthe Marches. Jo went to New York and became successful in her writing and had the satisfaction of seeing her work published there. But at home the bitterest blow was yet to fall. Beth had known for some time that she couldn’t live much longer to be with the family and in the spring time she died.News came from Europe that Amy and Laurie, the grandson of a wealthy neighbor, had planned to be married soon. Now Jo became ever more successful in her writing and got married to Professor Bhaer and soon afterwards founded a school for boys.And so the little women had grown up and lived happily with their children, enjoying the harvest of love and goodness that they had devoted all their lives to.56.The members of the March family were Father March, Mrs. March and their _____.A. four daughtersB. five daughtersC. son and four daughtersD. son and five daughters57.What does the sentence “Meg became Mrs. Brooke, and after a few family troubles got usedto her new state happily.” mean?A.

Natural substances such as animal droppings and straw have been used as fertilizers for thousands of years, and lime has been used since the Romans introduced it during the Empire. It was not until the nineteenth century, in fact, that chemical fertilizers became popular. T oday, both natural and synthetic fertilizers are available in a variety of forms.A complete fertilizer is usually marked with a formula consisting of three numbers, such as 4-8-2 or 3-6-4, whichdesignate the percentage content of nitrogen, phosphoric acid, and potash in the order stated.Synthetic fertilizers are available in either solid or liquid form. Solids, in the shape of chemical granules are popular because they are easy to store and apply. Recently, liquids have shown an increase in popularity, accounting for about 20 percent of the nitrogen fertilizer used throughout the world. Formerly, powders were also used, but these were found to be less convenient than either solids or liquids.Fertilizers have no harmful effects on the soil, the crop, or the consumer as long as they are used according to recommendations based on the results of local research. Occasionally, however, farmers may use more fertilizer than necessary, damaging not only the crop but also the animals or humans that eat it. Accumulations of fertilizer in the water supply ac celerate the growth of algae and, consequently, may disturb the natural cycle of life, contributing to the death of fish. Too much fertilizer on grass can cause digestive disorders in cattle and in infants who drink cow's milk.61. The word “essential” in line 2 could best be replaced by which of the following?A. limitedB. preferredC. anticipatedD. required62. Which of the following has the smallest percentage content in the formula 4-8-2?A. NitrogenB. PhosphorusC. AcidD. Potash63. The word "designate' in line 8 could be replaced by ________.A. modifyB. specifyC. limitD. increase64. The word "these" in line 14 refers to ________.A. powdersB. solidsC. liquidsD. fertilizers65. What happens when too much fertilizer is used?A. Local research teams provide recommendations.B. Algae in the water supplies begin to die.C. Animals and humans may become ill.D. Crops have no harmful effects.DDBACPaper TwoI.Fill in the blanks with proper words. The first letter is given.

(5%) Marijuana(大麻) is a part of my high school. The school is divided into two groups: those who smoke and those who don’t. Those who do, eat outside, even in 35-degree weather. The temptation to smoke is strong but it was not always so. As a first-year student, I was totally naive(天真的) about drugs. No one in my grade took them; I imagined that those whodid were poor, unloved and stupid. Cigarette smoke made me sick. Never, in my wildest dreams, did I imagine myself smoking a roll of pot(大麻叶) until the experience was a reality. I was curious. Having heard how great it was to float down the stream of consciousness, I tried it.The first time was exciting. I trembled, as the fear of getting caught appeared before me. I felt that I was taking a risk and that a policeman would suddenly take the evil thing from my hand, and replace it with handcuff(手铐). But no one ever gets arrested.Sometimes I wish they were. I know it’s terrible to wish evil upon another, because he or she would lose all opportunity to become perhaps a doctor or a lawyer. But then his parents would be aware that their child exists and that he is trying to express himself. He needs to be listened to.Marijuana never really attracted me because I could express myself through poetry and experience music without it. I like to know that all of me is here and that I control my entire body.Some scientists tell us that marijuana is not addictive(上瘾的), but when someone smokes a roll of pot with that peculiar look on his or her face, I can see how strong the attraction is. What I fear is that some kids don’t know when to stop. Mari juana is hurting us all.Answer the following questions in COMPLETE sentences.1.According to the article, smoking marijuana is not a major problem of some high schoolstudents, isn’t it?2.What made the author try marijuana?3.Was the author arrested because of trying a roll of pot for the first time?4.What does the third paragraph suggest?5.Why didn’t the author find pot attractive?1、Yes,it is.2、Curiosity.3、No,h e wasn’t.4、Those who smoke is trying to express himself.5、Because the author could express himself through poetry and experience music without it.VI.Translation (10%)1.据报道上海迪斯尼乐园的面积将是香港迪斯尼的四倍。

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.

Therefore,for the shrimps it is a race against time.By the12th day,however,when they are about3centimeters long,hundreds of tiny eggs form on the underbodies of the ually by this time,all that remains of the lake is a large,muddy patch of wet soil.On the13th day and the next,during the final hours of their brief lives, the shrimps lay their eggs in the mud.Then,having ensured that their species will survive,the shrimps die as the last of the water evaporates.If sufficient rain falls the next year to form another lake,the eggs hatch,and once again the shrimps pass rapidly through their cycle of growth,adulthood,egg-laying,and death.Some years there is insufficient rain to form a lake;in this case,the eggs will remain dormant for another year,or even longer if necessary.Very,very occasionally,perhaps twice in a hundred years,sufficient rain falls to form a deep lake that lasts a month or more. In this case,the species passes through two cycles of growth,egg-laying,and death.Thus,on such occasions,the species multiplies considerably,which further ensures its survival.51.Which of the following is the most distinctive feature of Mojave shrimps?A.They live a brief and tough life.B.They feed on plant and animal organisms.C.Their eggs can survive years of drought.D.They lay their eggs in the mud.52.The word“dormant”(in Para4)most probably means________.A.inactiveB.strongC.alertD.soft53.What can be inferred from the passage?A.Appearance and size are important factors for life to survive in the desert.B.A species must be able to multiply quickly in order to survive in the desert.C.For some species one life cycle in a year is enough to survive the desert drought.D.Some species develop a unique life pattern to survive in severe conditions.54.Which of the following statements is NOT a fact?A.The eggs of Mojave shrimps are as small as the grains of seeds.B.The whole cycle of growth of the shrimps is a race against time.C.It is difficult to believe that these shrimps can survive droughts in the desert.D.The amount of train has a strong impact on the number of the shrimps.55.The passage mainly deals with_____.A.the life span of the Mojave shrimpsB.the survival of desert shrimpsC.the creatures living in the Mojave desertD.the importance of water to life in the desert（B）The tourist trade is booming.With all this coming and going,you'd expect greater understanding to develop between the nations of the world.Not a bit of it!Superb systems of communication by air,sea and land make it possible for us to visit each other's countries at a moderate cost.What was once the‘grand tour’,reserved for only the very rich,is now within everybody's grasp.The package tour and chartered flights are not to be sneered at. Modern travelers enjoy a level of comfort which the lords and ladies on grand tours in the old days couldn't have dreamed of.But what's the sense of this mass exchange of populations if the nations of the world remain basically ignorant of each other'？Many tourist organizations are directly responsible for this state of affairs.They deliberately set out to protect their clients from too much contact with the local population.The modern tourist leads a cosseted,sheltered life. He lives at international hotels.where he eats his international food and sips his international drink while he gazes at the natives from a distance.Conducted tours to places of interest are carefully censored.The tourist is allowed to see only what the organizers want him to see and no more.A strict schedule makes it impossible for the tourist to wander off on his own;and anyway,language is always a barrier,so he is only too happy to be protected in this way.The sad thing about this situation is that it leads to the persistence of national stereotypes.We don't see the people of other nations as they really are,but as we have been brought up to believe they are.You can test this for yourself.Take five nationalities,say,French,German,English,American and Italian.Now in your mind,match them with these five adjectives:musical,amorous,cold,pedantic,native.Far from providing us with any insight into the national characteristics of the peoples just mentioned,these adjectives actually act as barriers.So when you set out on your travels,the only characteristics you notice are those which confirm your preconceptions.You come away with the highly unoriginal and inaccurate impression that,say,‘Anglo-Saxons are hypocrites’of that ‘Latin peoples shout a lot’.You only have to make a few foreign friends to understand how absurd and harmful national stereotypes are.But how can you make foreign friends when the tourist trade does its best to prevent you? Carried to an extreme,stereotypes can be positively dangerous.Wild generalizations stir up racial hatred and blind us to the basic fact—how trite it sounds!That all people are human.We are all similar to each other and at the same time all unique.56.What is the main idea of this passage?A.Tourism contributes nothing to increasing understanding between nations.B.The stereotypes of people lead to racism.C.Conducted tour is dull.D.Tourism has developed at past too a pace.57.What is the author’s attitude toward tourism?A.NeutralB.NegativeC.CriticalD.appreciative58.Which of the following can best explain the meaning of the underlined sentence?A.Modern tourists are lucky because of those efficient means of transportation.B.Modern tourists are“protected”too much.C.Modern tourists get to know foreign countries better.D.Modern tourists stay indoors too much.59.The purpose of the writer is to______.rm us of the possible ways to travel.B.persuade us to change the way of travelling.C.entertain us with some travel adventures.D.suggest an alternative of enhancing the understanding between nations.60.What is“grand tour”now?A.It is still very expensive.B.It’s still tiring and uncomfortable.C.Package tour made it less attractive.D.Everybody can enjoy the‘grand tour’.（C）When a consumer finds that an item she or he bought is faulty or in some other way does not live up to the manufacturer’s claims,the first step is to present the warranty,or any other records which might help,at the store61.When a consumer finds that his or her item has fault in it,the first thing he or she should do is to ___.plain personally to the managerB.threaten to take the matter to courtC.write a firm letter of complaint to the store of purchaseD.show some written proof of the purchase to the store62.How can a consumer make his or her complaint more effective,according to the passage?A.Explain exactly what is wrong with the item.B.Threaten to take the seller to court.C.Make polite and general statements about the problem.D.Avoid having direct contact with the store manager.63.According to the passage,which of the following is suggested as the last alternative that consumers may turnto?plain to the store manager in person.plain to the manufacturer.C.Write a complaint letter to the manager.D.Turn to the Consumers’Rights Protection Organization for help.64.The phrase “live up to ”in this context means:A.meet the standard ofB.realize the purpose ofC.fulfill the demands ofD.keep the promise of65.The passage tells us _____.A.how to settle a consumer’s complaint about a faulty itemB.how to make an effective complaint about a faulty itemC.how to avoid buying a faulty itemD.how to deal with complaints from customersPaper Two Ⅰ.Fill in the blanks with proper words.The first letter is given.Beijing’s annoying smog s___1___to have hurt the city’s appeal to st year ，Beijing Youth Daily reported that the number of visitors to Beijing had fallen 50percent since January.It’s said that the city’s bad air q___2___was responsible for the decline.It’s also more difficult to a___3___high-end employees to work in Beijing,especially those with children.of purchase. In most cases, this action will produce results. However, if it does not, there are various means the consumer may use to gain satisfaction. A simple and common method used by many consumers is to complain directly to the store manager. In general, the "high up" his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer's favor, assuming he or she has a just claim.Consumers should complain in person whenever possible, but if they can't get to the place of purchase, it is acceptable to phone or write the complaint in a letter.Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can demonstrate what is wrong with the item in question. If this can't be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, "The left speaker does not work at all and the sound coming out of the right one is unclear" is better than "This stereo does not work." The store manager may advise the consumer to write to the manufacturer. If so, the consumer should do this, stating the complaint as politely and firmly as possible. If a polite complaint does not achieve the desired result, the consumer can go to a step further. She or he can threaten to take the seller to court or report the seller to a private or public organization responsible for protecting consumers' rights.H___4___,the blanket of poisonous smog hasn’t hurt Beijing’s office market,which has jumped up quickly on a g___5___tanking to become the fourth-most-expensive location to rent office space in the world.According to a recent research,office space in Beijing’s Central Business District c___6___on average$1,412per square meter per year.That’s more expensive than No.5-ranked central Tokyo or No.6-ranked Madison&Fifth Avenues in New York.

Both of these criticisms are legitimate,but they beg the question of why so many Chinese still want to learn English.English,they recognize,is the lingua franca of the modern world.It is the language of business and has become the language of international___5___and culture.When people from different countries get together, they___6___speak in English rather than try to translate their native languages.It seems that everyone everywhere can speak at least some English.For China to be part of that international conversation,it is___7___that some level of English proficiency should be achieved.But what,you may ask,about those who will never speak a word of English once they leave school?Well,for good or ill,they will still be surrounded by English.It is there in signs,in music,in movies and in the casual conversations they overhear of the___8___number of foreigners on the city streets.To know English is to be included in the rest of the world,even if your world is___9___to China.I agree with Professor Zhang on one point,through.English should not be a compulsory subject in university. For most,passing the CET is just the endless drudgery（苦差事）of memorizing word lists.There is little emphasis placed on communication.And if you can’t communicate in English after years of study in primary school,middle school and high school,a few more years in university___10___won’t help.Ⅲ.Fill in the blanks with the proper form of each verb given.A shark was killed after___1___（drag）to shore at Yalong Berth beach in Sanya,South China’s Hainan Province,on Sunday afternoon.It was the first time a shark___2___（catch）in the beach area,a popular tourist site in Hainan.Local fishermen said they caught the3-meter-long,l-ton shark by chance when they___3___（fish）in sea water 1,000metres deep near the beach.The police temporarily protected the shark while oceanographers decided whether it was a species___4___（belong）to State protection.Fishermen later killed and sold the shark afteroceanographers___5___（confirm）that it was a whale shark and therefore not under State protection.The shark was believed to___6___（drift）into the area from the deep sea due to strong waves caused last week by Typhoon Imbudo.It had no open injuries but experts said they believed it suffered from internal___7___（bleed）.Local police officer Fu Chenggeng said beachgoers should not feel___8___（threaten）by sharks because the fish never attack human beings on their own initiative.Fu said he___9___（never hear）of any shark attacks at the Sanya beach since he first started work there eight years ago.However,police said they___10___（improve）the security system to safeguard tourists’safety on the beach in the next few months.Ⅳ.Sentence transformation.1.He realized that he had left his keys in his room as soon as he locked the door.（改成倒装句）2.The Eiffel Tower attracts thousands of travelers all over the world.（改成强调句，强调主语部分）3.His classmates often mistake him for his twin brother.It annoys him.（用主语从句和表语从句改写句子）4.As Mary was a thoughtful girl,she arranged everything so well that all went smoothly.（分词）5.The man in the middle talked about the incident in the way that he witnessed it.（同意改写，用虚拟语气）Ⅴ.Read the following passage and answer the questions in COMPLETE sentences. Relations between the United States and Spain were not very good in1898.On February15，a battleship called the USS Maine blew up and sank in the harbor at Havana,Cuba.More than260Americans were killed.Many Americans thought that Spanish saboteurs（破坏者）had set an underwater mine that caused the explosion.Witnesses and survivors had different visions of what happened.Some said that they heard two explosions.It was discovered that the magazine-which is a storage place for arms,ammunition（军火），and explosives—had exploded.Questions were raised about what caused the first explosion.Did the first explosion come from outside the ship,causing the magazine to explode?Or,did something on the ship blow up the magazine?Other witnesses said that there was only one explosion.If they are right,then what on the ship caused the magazine to explode?A theory supporting the two-explosion version was that rebels from Cuba had caused the explosion.The rebels were aware of the bad feelings between the United States and Spain.They would have been willing to cause trouble between the nations to bring an end to Spanish rule in Cuba.The United States government issued an ultimatum（最后通碟）to the Spanish government to end its occupation of Cuba.When Spanish officials refused,Congress and President William McKinley declared war on Spain.The war did not last long,because the United States forced an early surrender.More than100years after the explosion of Maine,the cause of the explosion is still unknown.Many questions remain.If an attack from outside the ship caused the magazine to explode,why didn’t witnesses see a splash in the water?Why were there no dead fish in the water if there was an external explosion?With the mystery still unsolved,the question of what really happened to the USA Maine may never be answered.Answer the questions in COMPLETE sentences:1.Why did more than260Americans lose their lives on February15,1898?2.Witnesses and survivors had the same versions of what happened,didn’t they?3.According to the passage,what was the“magazine”was used to do?4.According to the two-explosion version,what’s the probable purpose of the Cuban rebels to cause the explosion?5.What’s the main topic of the passage?Ⅵ.Translation1.不可否认的是，那些总是接触英语环境的人在英语学习方面具有优势。

(1,8)-，详解见解析．【解析】【分析】（1）将x=0代入抛物线公式2y=-x +2x-1求出y 值，即可得到抛物线与y 轴交点B 的坐标，平移后的抛物线的顶点为E(1,4)，可根据顶点式求出平移后抛物线的解析式；（2）因为抛物线向上平移4个单位，所以MN=4，又因为OM=ON ，可知点M 的纵坐标为-2，将y=-2代入原抛物线2y=-x +2x-1，即可求出x 值，点M 的坐标就可以表示出来． （3）要使C 、F 、P 为顶点的三角形为直角三角形，可以画一个以C 、F 为直径的圆（直径对应圆周角为直角），交抛物线对称轴x=-1可得点1P 、2P 的坐标解，另外可以使∠PCF=90°或∠CFP=90°，可分别得出点3P 、4P 的坐标解．【详解】解：（1）抛物线2y=-x +2x-1与y 轴相交于点B ，将x=0代入，求得y=-1，∴B 点坐标(0，-1)．∵设平移后的抛物线为2y=-(x-h)+k ，顶点为E(1,4)，即h=1，k=4，∴2y=-(x-1)+4，即平移后的抛物线为22y=-(x-1)+4=-x +2x+3．（2）如上图所示，∵原坐标顶点A(1，0)，平移后抛物线顶点为E(1,4)，∴抛物线向上平移了4个单位，即MN //y 轴，MN ⊥x 轴，又∵OM=ON ，MN=4，∴点O 在垂直平分线上，点M 、N 关于x 轴对称，∴M 点的纵坐标为–2，将y=-2代入2y=-x +2x-1，得：222-x +2x-1=-2-(x -2x+1)=-2(x-1)=2x=12± 解得：x=12±，∴点M 的坐标为(1+2-2)，或(1-2-2)，． （3）存在，且1P (1,1)，2P (1,6)-，3P (12)，，4P (1,8)-． 如图所示，点P 一共有四种结果，∵C 点为平移后的解析式与x 轴的左交点，将y=0代入2y=-x +2x+3，得x=-13或， ∴C(-1，0)，且点B(0，-1)，将点B(0，-1)、C(-1，0)代入直线BC 解析式为：y=kx+b ， ∴-k+b=0b=-1⎧⎨⎩，解得：k=-1b=-1⎧⎨⎩，即直线BC 解析式：y=-x-1， 根据题意可知，直线BC 与平移后的解析式相交于点F ，∴2y=-x-1y=-x +2x+3⎧⎨⎩，解得：x=-1（舍）或4，y=-5，即F(4，-5)， ∵要使C 、F 、P 为顶点的三角形为直角三角形，可以画一个以C 、F 为直径的圆，该圆与抛物线对称轴x=-1交点即为点P （因为圆的直径对应的圆周角为90°，即∠CPF=90°）∴以C 、F 为直径的圆，圆心为线段CF 的中点(32，5-2)，直径为线段CF 的长∴圆的方程为：22235x-+y+=22()()，将x=1代入圆的方程，得：y=1或-6， 即1P (1,1)，2P (1,6)-， ∵直线CF 解析式：y=-x-1，即斜率k=-1，即直线CF 与x 轴夹角为45°，要使C 、F 、P 为顶点的三角形为直角三角形，则使∠PCF=90°，直线CP 与x 轴夹角也为45°，即直线CP 斜率为1，直线CP 的解析式为：y=x+1，此时该直线与抛物线对称轴x=1的交点为3P (1,2)，又∵直线CF 解析式：y=-x-1，即斜率k=-1，即直线CF 与x 轴夹角为45°，要使C 、F 、P 为顶点的三角形为直角三角形，则使∠CFP=90°，直线FP 与x 轴夹角也为45°，即直线FP 斜率为1，直线FP 的解析式为：y=x-9，此时该直线与抛物线对称轴x=1的交点为4P (1,-8)．【点睛】本题考查了一元二次函数与坐标轴、直线的交点，一元二次函数的平移及应用，圆的直径所对应的圆周角为直角等知识点，该题有一定的难度，所以一定要结合图形进行分析，这样才不会把解遗漏．7．（1）PM ＝PN ，PM ⊥PN ；（2）△PMN 是等腰直角三角形．理由见解析；（3）S △PMN 最大＝492． 【解析】【分析】（1）由已知易得BD CE =，利用三角形的中位线得出12PM
