山西省运城中学、芮城中学2018-2019学年高二上学期期中联考英语试卷
芮城中学、运城中学2018-2019学年第一学期期中考试高二英语试题本试题共150分，时间120分钟2018年11月第I卷第一部分阅读理解(共两节,满分60分)第一节（共15小题；每小题3分，满分45分）AOxford and Cambridge have now decided to remove the words CAN'T and IMPOSSIBLE from their dictionary. Jessica Cox, 25, a girl born without arms, stands inside an aircraft. The girl from Tucson, Arizona got the Sport Pilot certificate lately and became the first pilot licensed to fly using only her feet. Jessica Cox of Tucson was born without arms, but that has only stopped her from doing one thing: using the word "can't".Her latest flight into the seemingly impossible is becoming the first pilot licensed to fly using only her feet.With one foot manning the controls and the other delicately guiding the steering column, Cox, 25, soared to achieve a Sport Pilot certificate. Her certificate qualifies her to fly a light-sport aircraft to altitudes of 10,000 feet."She's a good pilot. She's rock solid," said Parrish Traweek, 42, the flying instructor at San Manuel's Ray Blair Airport. Parrish Traweek runs PC Aircraft Maintenance and Flight Services and has trained many pilots, some of whom didn't come close to Cox's abilities."When she came up here driving a car," Traweek recalled, "I knew she'd have no problem flying a plane."Doctors never learned why she was born without arms, but she figured out early on that she didn't want to use prosthetic devices. So, the next time you are ready to tell yourself, "I can't possibly..." remember this amazing young woman and change your vocabulary.1. The word CAN'T will be removed from the two dictionaries because of ______.A. the first woman pilotB. a very special flight serviceC. a great flight with a light-spot aircraftD. the flight in a seemingly impossible way2. According to Parrish Traweek, Jessica Cox_____.A. flies the plane by standing in itB. is good at driving a car with her legsC. has been her workmate for two yearsD. is one of the best pilots trained by her3. What can be known from the text?A. Jessica Cox has been armless for 25 years.B. Jessica Cox was normal when she was young.C. There are no suitable prosthetic devices for Jessica Cox.D. The doctors have discovered how Jessica Cox lost her arms.4. The best title for the text may be "_______".A. Flying with no handsB. Jessica Cox, a disabled pilotC. Living with a positive attitudeD. Two words will disappear from dictionariesBWhen Boris left school, he could not find a job. He tried hard and pestered (纠缠)his relatives, but they had problems of their own. He answered advertisements until he could not afford to buy any more stamps. Boris grew annoyed, then depressed, then a little hardened. Still he went on trying and still he failed. He beganto think that he had no future at all.“Why don't you start your own business?”one of his uncles told him. “The world is a money-locker. You'd better find a way of opening it.”“But what can I do？”“Get out and have a look round,”advised his uncle in a vague sort of way. “See what people want; then give it to them, and they will pay for it.”Boris began to cycle around the town and found a suitable piece of a waste ground in the end. Then he set up his business as a cycle repairer. He worked hard, made friends with his customers and gradually managed to build up his goodwill and profit. A few months later, he found that he had more work than he could deal with by himself. He found a number of empty shops but they were all no good：in the wrong position，too expensive or with some other snag(障碍)．But at long last, he managed to find an empty shop on a new estate（土地，地区）where there were plenty of customers but no competition.Boris and his assistant taught themselves how to repair scooters and motorcycles. Slowly but surely the profits increased and the business developed. At last, Boris hadmanaged to open the moneylocker and found bank notes and gold coins inside.5. Which of the following would be the BEST title for the passage?A. Goodwill is the key to successB. The world is a moneylockerC. No education, no futureD. Difficulty of starting a small business6. Boris started his career by________.A. cycling around the townB. developing a waste groundC. repairing cyclesD. buying empty shops7. Boris finally chose an empty shop on a new estate because________.A. it was not so expensiveB. he had a lot of old customers thereC. he could make good use of his skills thereD. there were good opportunities there8. We can infer from the last paragraph that Boris______.A. still couldn't make good profitsB. set off in a successful careerC. found a lot of gold coins by accidentD. had great difficulty running his businessC9. If you like swimming, you will chooseA. Banbury HouseB. Three SeasonsC. Sturtin HotelD. Downtown Digs10. In what way is Downtown Digs different from the other residences?A. It is comfortable.B. It is expensive.C. It is cheap.D. It is quiet.11. If you would like to live as close as possible to the university, you'd better chooseA. Banbury HouseB. Three SeasonsC. Downtown DigsD. Hilton HostelDGolden eagle populations in the UK are set to increase as some chicks are reintroduced to the north of England. Ten birds will be released(释放)from south of Edinburgh in summer 2018, with the hope of bringing the species back from disappearing in England. More eagles will be released in the summertime of the next five years.The project received ￡1.3 million of lottery funding in March and has now been awarded a further ￡150,000 to employ workers to run the operation. Project manager Cat Barlow said: “This is a really exciting time as the project is now starting to happen and we will soon start to see its benefits. Work will start next summer, when we will collect a number of golden eagle chicks in the Highlands and bring them south to be reared and released from an already selected place.”The birds will be released with satellite tracking tags that will allow the scientists to gather information about their behavior and find if they suddenly go offline.Recently, golden eagles have died out in England as the last known individual is believed to have died. Due to the popularity of shooting birds of prey(食肉猛禽), those birds in the wild struggle to survive. Main causes of death are systematic poisoning, shooting and nest disturbance by gamekeepers.It is hoped that the newly released birds will move further south in search of new living areas and food supplies. The project expects to see the number of wild birds in Scotland and England increase as the range of the animals develops. While the birds were gone in England, in the Highlands of Scotland the number of golden eagles rocketed. With up to 500 breeding pairs, the chicks will be sourced from here. It is hoped that golden eagles may finally return to the north of England, and if all goes well, numbers should grow steadily.12．Why will some golden eagles be set free from south of Edinburgh?A．To keep the balance of natureB．To prevent eagles from dying outC．To bring back the number of other speciesD．To encourage more birds to live in the wild13．Which word can replace the underlined word “reared” in Paragraph 2?A．Raised B．Stored C．Sold D．Exhibited14．What does Paragraph 4 focus on ?A．Harmful effects of shooting birdsB．Why animal hunting should be forbiddenC．Reasons for golden eagles’ dying outD．The difficult situation golden eagles face15．What is the author’s attitude towards the golden eagle project?A．Ambiguous B．Cautious C．Doubtful D．Hopeful 第二节(共5小题；每小3分，满分15分)根据短文内容，从短文后的选项中选出能入空白处的最佳选项。
