y 时，没有考虑0=k 与斜率不存在的情形，实际上就是承认了该直线的斜率是存在的，且不为零，这是不严密的．第二，题中要求直线与抛物线只有一个交点，它包含相交和相切两种情况，而上述解法没有考虑相切的情况，只考虑相交的情况．原因是对于直线与抛物线“相切”和“只有一个交点”的关系理解不透．第三，将直线方程与抛物线方程联立后得一个一元二次方程，要考虑它的判别式，所以它的二次项系数不能为零，即,0≠k 而上述解法没作考虑，表现出思维不严密．（2）高中数学中有许多题目，求解的思路不难，但解题时，对某些特殊情形的讨论，却很容易被忽略．改生没有考虑到直线存在的特殊情况以及相交只有一个交点时的特殊情况，均导致了题目解析错误，说明该生审题不认真，对于直线的表示形式没有理解透彻，也没有掌握一定的做题方法，如数形结合．（3）①当所求直线斜率不存在时，即直线垂直x 轴，因为过点)1,0(，所以,0=x 即y 轴，它正好与抛物线x y 22=相切．②当所求直线斜率为零时，直线为y =1平行x 轴，它正好与抛物线x y 22=只有一个交点．③一般地，设所求的过点)1,0(的直线为1+=kx y )0(≠k ，则⎩⎨⎧=+=x y kx y 212，∴.01)22(22=+-+x k x k 令,0=∆解得k =12，∴所求直线为.121+=x y 综上，满足条件的直线为：.121,0,1+===x y x y 六、教学设计题（本大题1小题，30分）17．【参考答案】（1）教学目标：1、知识与技能：掌握三角恒等变换公式，能用三角恒等变换公式及二倍角公式正确解决简单的三角恒等变换问题．2、过程与方法：通过解决简单三角恒等变换问题，提升基础知识到实际运用的能力．3、情感态度价值观：从问题的前后设置，感受数学知识运用的联系，体会逆向使用公式的思想，提高推理能力，激发数学学习的兴趣．教学重难点：1、教学重点：运用三角恒等变换公式解决简单的三角恒等变换问题．2、教学难点：运用三角恒等变换公式以及倍角公式正确解决简单的三角恒等变换问题．（2）转化思想、类比思想（3）教学过程：一、复习引入：复习三角函数和差公式以及倍角公式二、探索新知：问题：思考α与2α的关系．尝试用cos α表示222sin ,cos ,tan 222ααα总结出：222sin ,cos ,tan 222ααα三、课堂练习：求证：（1）sin αcos β=1/2[sin(α+β)+sin(α-β)];（2）sin sin 2sin cos 22θϕθϕθϕ+-+=证明：（1）因为sin(α+β)=sin αcos β+cos αsin βsin(α-β)=sin αcos β-cos αsin β将以上两式的左右两边分别相加得sin(α+β)+sin(α-β)=2sin αcos β即sin αcos β=1/2[sin(α+β)+sin(α-β)]（2）有（1）可得sin(α+β)+sin(α-β)=2sin αcos β设α+β=θ，α-β=φ那么α=(θ+φ)/2,β=(θ-φ)/2把α，β的值带入（1）即得sin sin 2sin cos

Beneath each question there are four choices respectively marked by letters A, B, C and D. Choose the right answer for each question. Write your answers on the answer sheet.Passage 1Solar energy for your home is coming. It can help you as a single home owner. It can help the whole country as well. Whether or not solar energy can save your money depends on many things. Where you live is one factor. The type of home you have is another. Things like insulation present energy costs, and the type of system you buy are added factors.Using solar energy can help save our precious fuel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. And when Mother Nature says that’s all. The only way we can delay hearing those words is by starting to save energy now and by using other sources, like the sun.We won’t have to worry about the suns running out of energy for another several billion years or so. Besides as an endless source of energy, the use of the sun has other advantages as well. The sun doesn’t offer as many problems as other energy sources. For example, fossil fuel plants add to already high pollution levels. With solar energy, we will still need sources of energy, but we won’t need as mu ch. That means we can cut down on our pollution problems.With all these good points, why don’t we use more solar power? There are many reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy. All that is changing now. Solar costs are starting to equal the costs of oil and electricity. Experts say that gas, oil and electricity prices will continue to rise. The demand for electricity is increasing rapidly. But new power plants will use more gas, oil or coal. Already in some places the supply of electricity is being rationed. Solar energy is now in its infancy. It could soon grow to becomea major part of our nations energy supply.41. Which statement best expresses the main idea?[A] Something about Solar Energy and Pollution.[B] Solar Energy.[C] Energy and Pollution.[D] Energy and Money.42. Solar energy can help us save __________.[A] the earth and natural resources [B] mother nature[C] the sun [D] our precious fuel43. The sun is an endless source of energy, it will not run out of it for __________.[A] several million years [B] several hundred years[C] several billion years [D] several thousand years44. Which of the following statements is correct?[A] Energy from coal would not pollute our living environment.[B] Energy from natural gas would not pollute our living environment.[C] Energy from the sun would not pollute our living environment.[D] Energy from oil would not pollute our living environment.45. Solar energy is now in its infancy, __________.[A] but it will be considered as an important part of our nation’s energy supply[B] yet we will build more power plants[C] and the supply of electricity will be rationed[D] but we don t need practice energy rationing nowPassage 2In this age of Internet chat, videogames and reality television, there is no shortage of mindless activities to keep a child occupied. Yet, despite the competition, my 8-year-old daughter Rebecca wants to spend her leisure time writing short stories. She wants to enter one of her stories into a writing contest, a competition she won last year.As a writer I know about winning contests, and about losing them. I know what it is like to work hard on a story only to receive a rejection slip from the publisher. I also know the pressure of trying to live up to a reputation created by previous victor ies. What if she doesn’t win the contest again? That’s the strange thing about being a parent. So many of our own past scars and dashed hopes can surface.A revelation (启示) came last week when I asked her, “Don’t you want to win again?”“No,” she replied, “I just want to tell the story of an angel going to first grade.”I had just spent weeks correcting her stories as she spontaneously (自发地) told them. Telling myself that I was merely an experienced writer guiding the young writer across the hall, I offered suggestions for characters, conflicts and endings for her tales. The story about a fearful angel startin g first grade was quickly “guided” by me into the tale of a little girl with a wild imagination taking her first music lesson. I had turned her contest into my contest without even realizing it.Staying back and giving kids space to grow is not as easy as it looks. Because I know very little about farm animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting (借用) my daughter’s experience.While stepping back was difficult for me, it was certainly a good first step that I will quickly follow with more steps, putting myself far enough a way to give her room but close enough to help if asked. All the while I will be reminding myself that children need room to experiment, grow and find their own voices.46. What do we learn from the first paragraph?[A] A lot of distractions compete for children’s time nowadays.[B] Children do find lots of fun in many mindless activities.[C] Rebecca is much too occupied to enjoy her leisure time.[D] Rebecca draws on a lot of online materials for her writing.47. What did the author say about her own writing experience?[A] She was constantly under pressure of writing more.[B] Most of her stories had been rejected by publishers.[C] She did not quite live up to her reputation as a writer.[D] Her way to success was full of pains and frustrations.48. Why did Rebecca want to enter this year’s writing contest?[A] She had won a prize in the previous contest.[B] She wanted to share her stories with readers.[C] She was sure of winning with her mother’s help.[D] She believed she possessed real talent for writing.49. The author took great pains to refine her daughter’s stories because __________.[A] she wanted to help Rebecca realize her dreams of becoming a writer[B] she was afraid Rebecca’s imagination might run wild while writing[C] she did not want to disappoint Rebecca who needed her help so much[D] she believed she had the knowledge and experience to offer guidance50. What’s the author’s advice for parents?[A] Children should be given every chance to voice their opinions.[B] Parents should keep an eye on the activities their kids engage in.[C] Children should be allowed freedom to grow through experience.[D] A writing career, though attractive, is not for every child to pursue.Passage 3Foxes and farmers have never got on well. These small dog-like animals have long been accused of killing farm animals. They are officially classified as harmful and farmers try to keep their numbers down by shooting or poisoning them.Farmers can also call on the services of their local hunt to control the fox population. Hunting consists of pursuing a fox across the countryside, with a group of specially trained dogs, followed by men and women riding horses. When the dogs eventually catch the fox they kill it or a hunter shoots it.People who take part in hunting think of it as a sport; they wear a special uniform of red coats and white trousers, and follow strict codes of behavior. But owning a horse and hunting regularly is expensive, so most hunters are wealthy.It is estimated that up to 100,000 people watch or take part in fox hunting. But over the last couple of decades the number of people opposed to fox hunting, because they think it is brutal (残酷的), has risen sharply. Nowadays it is rare for a hunt to pass off without some kind of confrontation (冲突) between hunters and hunt saboteurs (阻拦者). Sometimes these incidents lead to violence, but mostly saboteurs interfere with the hunt by misleading riders and disturbing the trail of the fox’s smell, which the dogs follow.Noisy confrontations between hunters and saboteurs have become so common that they are almost as much a part of hunting as the pursuit of foxes itself. But this year supporters of fox hunting face a much bigger threat to their sport. A Labour Party Member of the Parliament, Mike Foster, is trying to get Parliament to approve of a new law which will make the hunting of wild animals with dogs illegal. If the law is passed, wild animals like foxes will be protected under the ban in Britain.51. Rich people in Britain have been hunting foxes __________.[A] for recreation [B] in the interests of the farmers[C] to limit the fox population [D] to show off their wealth52. What is special about fox hunting in Britain?[A] It involves the use of a deadly poison.[B] It is a costly event which rarely occurs.[C] The hunters have set rules to follow.[D] The hunters have to go through strict training.53. Fox hunting opponents often interfere in the game __________.[A] by resorting to violence [B] by confusing the fox hunters[C] by taking legal action [D] by demonstrating on the scene54. A new law may be passed by the British Parliament to __________.[A] prohibit farmers from hunting foxes[B] forbid hunting foxes with dogs[C] stop hunting wild animals in the countryside[D] prevent large-scale fox hunting55. It can be inferred from the passage that __________.[A] Something about Solar Energy and Pollution.[B] limiting the fox population is unnecessary[C] hunting foxes with dogs is considered cruel and violent[D] fox-hunting often leads to confrontation between the poor and the richIV. Translation. (2 points for each, altogether 10 points)Directions: Translate the following Chinese sentences into English by using the words given in the brackets. Write your answers on the answer sheet.56. 她看起来仿佛刚从外太空回来似的。

For questions 8-10,completethe sentences with the information given in the passage.Space Our Future in Space: It Has Already Begun!We are all space travelers. But we’ve stayed close to home until now. One day,we may leave our “mother ship”Earth to make our home among the stars.A giant, spherical “spaceship”, about 8,000 miles in diameter, is speedingthrough the solar system right now. It is cruising at an incredible 66,600 milesper hour.It’s not a giant, Star Wars mother ship. It’s spaceship Earth, the home ofover four billion people. This water coated spaceship has been traveling throughthe universe for about five billion years. Only within the past 25 years, however,have some of its passengers broken free of Earth’s gravityBut 25 years from now, many people, including you, might live in an orbitingspace station 200 miles above the Earth.Space CitiesScientists have already designed special space factories. These factories will take advantage of the absence of gravity (zero gravity) to produce everything from life saving drugs to perfect ball bearings.Other scientists have designed space colonies, complete with farms, schools,and artificial day and night. Hundreds, or even thousands, of people will live, work,play—even go toschool, far above the Earth.Our conquest of space, of course, has already begun. We have explored part of the Moon, sent robot spaceships onto the surface of Venus and Mars, and aimed space probes past the planets of Jupiter and Saturn.Last June, one robot ship, Pioneer 10, left our solar system forever. Andastronauts from both the Soviet Union and the United States have lived in spacestations.The conquest of space, without question, is one of the greatest adventures human beings have ever set out on. But it may be more than a great adventure. Some scientiststhink the conquest of space may be a necessity for survival of the human species.We are tearing up more and more of the Earth to get raw materials for industry.And we are polluting the air and water as we manufacture products that we need or want. Almost everything that seems to make our lives more comfortable, and fromelectricity to pesticides, uses up or alters a piece of our planet’s natural environment.Why Go into Space?Yet our solar system is full of resources. The moon is chockfull of valuable metals. So are the asteroids, the small, rocky, planet like bodies orbiting the sun most of them between Mars and Jupiter. These metals, if we can get them, could be used to build factories and space stations.Also, in space, there is no atmosphere to filter out the sun’s energy. There is plenty of solar energy to be turned into electricity for manufacturing, for creating comfortable living conditions.Getting away from Earth has other advantages, too. Modern industry uses manykinds of metal alloys (mixtures of metal thatare better for certain purposes thanpure metals). Yet some metal alloys either can’t be made or are very expensive to make on Earth because of gravity. For instance, certain metals don’t mix well onEarth. But in zero gravity, molten (hot, liquid) metals mix more evenly. This is because there is no gravity to pull the heavier metals down, while the lighter ones float on top.From space, too, we can look down on the Earth and study the atmosphere, its weather, and the effects of air pollution.And because there is no strong gravity to break free from, our future homes away from Earth will be convenient starting points for travel to distant planets.But, while going into space might solve some problems, outer space can also be a dangerous place. For example, in outer space, we have to protect ourselves from the dangers of ultraviolet light and cosmic rays. Ultraviolet light from the sun can give us bad sunburns right here on Earth. Yet, Earth’s atmosphere screens out most of that harmful radiation. Cosmic rays are tiny high energy particles from outer space. Again, the Earth shields us from most of them.At Home in Space?But in space, without special protection, we would be exposed to much stronger radiation from ultraviolet light and cosmic rays. Also, in the zero gravity of outer space, our bones will lose calcium and become weaker. This will be more of a problem the longer people stay out in space. Doctors are looking for a way to keep our bones from losing calcium in outer space. And a small spaceship just might “drive you batty” after a while. But even on a short trip in outer space, you might not feelas well as you’d like to. Space travel could make you seasick!Yet, these risks won’t keep people from going into space. Eventually, an Earth like environment will be built in space. And they will be populated by people with many different interests: medicine, construction, farming, teaching, mining, and so on.The next hundred years will be filled with other worldly adventures, exciting scientific discoveries, and danger, as humans leave Earth—perhaps forever.Aging in SpaceSuppose a space traveler is moving at a velocity of 186,200 miles per second.For every hour that passes for him, 30 hours pass on Earth. If he travels for a year in this fashion (having accelerated instantaneously) and then turns around and comes back at this speed (having turned around instantaneously), he will find that while he has seemed to himself to have traveled two years, the men on Earth would claim he had been absent for 30 years.Suppose the space traveler had left at the age of 30, leaving behind a twin brother also aged 30. When he returned he would be 32, but his stay at home twinbrother would be 60. That is why the “clock paradox”, is sometimes called the “twin paradox”.Of course it takes quite a long while to accelerate to a high speed, and a long while to make a turn and head back again, so conditions aren’t quite as clear cut as just described.1.The giant, spherical spaceship mentioned in the passage is.［A］the outer space［B］a man made spaceship［C］the planet Earth［D］the Star Wars mothe ship2.Some persons have traveled into outer space after conquering within the past 25years.［A］the universe［B］Earth’s gravity［C］the earth［D］outer space3.We have explored or sent robot spaceships to the following space except.［A］the moon［B］Venus［C］Jupiter［D］Mars4.Why is the conquest of space more than a great adventure?［A］Because it is full of challenges for human beings.［B］Because it may be necessary for human beings to survive.［C］Because it is the greatest adventure in human history.［D］Because it is more exciting than any other adventures.5.The moon and the asteroids are alike with respect to their .［A］size and moving ways［B］comfortable living conditions［C］rich and valuable metals［D］solar energy6.Why can’t ultraviolet light scorch our skin on Earth as seriously as it does in space places?［A］Because the Earth’s atmosphere can make ultraviolet light less harmful.［B］Because ultraviolet can’t reach the Earth at all.［C］Because the Earth is far away from those planets radiating ultraviolet light.［D］Because other space places is near from those planets radiating ultravioletlight.7.In spite of many risks, scientists will finally build in space suitable for humans to live.［A］an environment without ultraviolet light［B］a lot of homes［C］an Earth like environment［D］an environment with atmosphere8.The reason some metal alloys can’t be made on Earth is that the heavier metals together with the lighter ones.9.In space, there is no atmosphere to filter out the sun’s energy. There is plentyof solar energy to be turned into, for creating comfortable living conditions.10.According to the author, will be caused to a man in gravity free space.Part III Listening Comprehension(35 minutes)Section ADirections: In this section, you will hear 8 short conversations and 2 long conversations.

第I卷（共90分）I. Listening Comprehension （25 分）Section A （每题1分，共10分）Directions: In Section A, you will hear ten short conversations between two speakers. At the end of each conversation, a question will be asked about what was said. The conversations and the questions will be spoken only once. After you hear a conversation and the question about it, read the four possible answers on your paper, and decide which one is the best answer to the question you have heard.II. Grammar and Vocabulary (每题1 分,共20 分)Section ADirections: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, used one word that best fits each blank.An implant that can cool nerves to block pain signals has been unveiled by researchers who say the device could offer an alternative to drugssuch as opioids (类鸦片活性肽).The team behind the device say it could bring benefits for management of acute pain such as (21)_______ experienced after amputations (截肢)or nerve grafts."We are optimistic that this represents a very promising starting point for an engineering approach (22)_______ treating pain,” said Prof John Rogers of Northwestern University in the US, a co-author of the research. But he cautioned that it might be some time (23) _______ they were available to patients. "As with any implantable device, the regulatory process can be slow, typically (24) _______ (involve) much more extensive animal model studies over a period of years," he said.Writing in the journal Science, the team report that the device to block pain signals, which (25) _______(test) only on rats so far, involves a pump, external control system and an implant made from a soft, rubbery substance. The latter forms a sealed collection of tiny channels which form a twisting path in the part of the implant that sits around the target nerve like a cuff.When liquid coolant and dry nitrogen flow through the implant, the liquid causes a drop in temperature. An electronic sensor in the device allows the temperature at the nerve (26) _______(keep) constant."All body processes are based on metabolic chemical reactions, motions of ions and flows of fluids--all (27) _______slow down as a result ofcooling,” said Rogers. “ The net effect when cooling is applied to a nerve is in blocking of electrical signals."Among their experiments, the team tracked two rats with an injury, recording over a three- week period the minimum force that (28)_______be applied to the hind paw to cause the animal to retract (缩回)it. This data was then compared against three rats who were similarly injured but also had the implant. The results suggest bouts of cooling of the injured nerve from 37℃ to 10℃led to (29) _______(severe) pain, with a sevenfold increase in the force that could be applied to the paw. The team say the implant’s benefits include (30)_______, in contrast to opioids, it is not addictive. As the implant is made with water-soluble and biocompatible materials, it can break down in the body after use. The implant could be inserted as an extension of the patient’s initial surgery.Section BDirections: Complete the following passage by using the -words in the box. Each word can only be used once. Note that there is one more word than you need.A. attachedB. bottle-fedC. confusionD. invisibleE. originallyF. orphanedG. partneringH. procedureI. reproducedJ. subjectsK. unintentionallySaving Baby BearsReacting to the auditory assault of barking dogs, shouts and rifle blasts, a 168-pound American black bear shot out and hightailed (迅速逃走)it into the woods off a logging road.His sister, weighing in at 135 pounds, took a little more time to overcome her fear and (31) _______ before she, too, ran for the trees and away from the humans who had driven more than 100 miles to witness the bears’ return to the wild.The cubs were the 106th and 107th (32) _______ or injured bears to be raised or treated at the Progressive Animal Welfare Society (PAWS) Wildlife Center in Washington state, then released months later in the same general area where they were (33) _______found. Fitted with GPS collars and tattooed with identification numbers on their gums, the bears are also among the latest (34) _______of a long-term research study being conducted by Rich Beausoleil and Lindsay Welfelt, both biologists and bear and cougar specialists.The siblings were only two weeks old when a forest worker and his dog (35) _______ disturbed their den in February 2020, scaring away their mother. She never returned.The worker contacted the WDFW, an agency (36) _______with PAWS to rehabilitate sick, injured wild animals before releasing them back into their natural habitats."Their eyes and ears weren't open, and their teeth hadn't evenerupted,Jennifer Convy, PAWS senior director of wildlife, said of the cubs, which each weighed less than 2 pounds when they arrived and were the youngest ever to be raised at the center.Though (37) _______at first, the cubs weren't cuddled. Instead, their caregivers wore bear- scented bear suits during feedings once the cubs' eyes had opened. At PAWS, the staff and volunteers take pains to be (38)_______to all the animals in their care."They don't see us, ever. We don't talk to them. We don't name the animals because we don't want our staff or volunteers to get (39)_______，“ Convy said. After more than a year, the bear siblings were released.The wildlife biologists are studying how the bears raised at PAWS fare after their release, compared to their wild-reared brethren. One cub released in 2017 had her first litter of cubs in January."We've been to her den several times." Beausoleil said. "She (40)_______ and had cubs of her own ... This was kind of a turning point for us."After all, the whole point of PAWS' rehabilitation "is to protect and perpetuate (使持续) the species," he said.III. Reading Comprehension (45 分)Section A (每题1分，共15分)Directions: For each blank in the following passage there are four wordsor phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.The Other da Vinci CodeFor centuries, two of the most intriguing questions about Leonardo da Vinci's "Mon a Lisa" were "Who " and "When ”A(n) (41) _______made at Heidelberg University in 2005 pretty much answered both. A note written in a manuscript in the library (42) _______the account of da Vinci's first biographer, Giorgio Vasari: that the sitter was a merchanfs wife, Lisa Gherardini. The note also helped date the masterpiece to between 1503 and 1506.A(n) (43)_______ mystery-"Where "- is still in dispute. But on June 3rd a French engineer, Pascal Cotte, declared that he and a collaborator had (44) _______the landscape in the background of the painting. Arguments had (45)_______ been made for stretches of countryside in the Marche region and between Milan and Genoa. During a presentation in Vinci, near Florence, Mr Cotte maintained that the artist was more plausibly depicting a part of his native Tuscany 一one that keenly interested him at the time. According to this theory, da Vinci represented the area not as it was, but as, in an unrealised scheme, he (46) _______ it to be.Mr Cotte, who was asked by the Louvre (where the "Mona Lisa" hangs) to create a digital image of the painting, is the inventor of themultispectral camera: a device that can detect not only the drawing below the (47) _______of an oil painting, but also, where they exist, intermediate layers of work. It was among these, under what appears to be a pointed rock, that he found a(n) (48) _______sketch showing that da Vinci meant it to represent a castellated tower.The landscape of the "Mona Lisa" also includes a huge overhanging cliff. That is (49)_______ to one that da Vinci included in a sketch of a fortress (堡垒)contested by Pisa and Florence in the war that flared between them in 1503 (around the time he was painting Gherardini). The (50)_______ with the nearby cliff ——and a tower, known as the Caprona tower 一all overlook the river Amo as it snakes from Florence to Pisa. All three also feature in drawings made by da Vinci to illustrate a plan about which, says Mr Cotte, he became “(51) _______”.This involved diverting the Amo to (52) _______Pisa's water supply and give Florence an outlet to the Mediterranean. In the early 1500s, with the two citystates at war, the idea was under active consideration. Mr Cotte argues that a(n) (53) _______ winding through desolate countryside at the right of the "Mona Lisa" is too wide to be a road, as some have speculated, and is(54) _______the driedup bed of the Amo as da Vinci envisaged (设想)it once his plan had been adopted.It never was. But if Mr Cotte's theory is right, it might just explain why Gherardini, a Florentine, exhibits such a contented, if mysterious, (55)_______。
