练案[34]选择性必修第四册UNIT 3 SEA EXPLORATION Ⅰ.阅读理解A(2023·河北省衡水中学月考) British sculptor Jason Taylor has made it his mission to use his talent to conserve our ecosystems by creating underwater museums.Over the years, the environmentalist has put over 850 massive artworks underwater worldwide.On February 1,2021, Taylor launched his latest work The Underwater Museum of Cannes.“The main goal was to bring attention to the fact that our oceans need our help，”Taylor told Dezeen, an architecture and design magazine.“Oce an ecology has been destroyed by human activity in the Mediterranean over the past few decades, and it is not obvious what is taking place when observing the sea from afar.”The Underwater Museum of Cannes contains 6 sculptures featuring local residents of various ages.They range from Maurice, an 80-year-old fisherman, to Anouk，a 9-year-old student.Towering over 6 feet and weighing 10 tons, the faces are sectioned into two parts, with the outer part like a mask.The mask indicates that the world's oceans appear powerful and unbeatable from the surface but house an ecosystem that is extremely fragile due to careless human activity.Though the waters surrounding the sculptures now appear a pristine blue, the seabed was filled with old boat engines, pipes, and other human-made trash when the project began about four years ago.Besides removing the trash, Taylor also restored the area's seagrass.Just one square meter of the seagrass can generate up to 10 liters of oxygen daily.The seagrass also helps prevent coastal erosion and provides habitats for many ocean creatures.“The idea of creating an underwater museum was to draw more people to the underwater environment and develop a sense of care and protection，”Taylor told Dezeen.“If we threw unwanted waste near a for est, there would be a public outcry.But this is happening every day in our surrounding waters and it largely goes unnoticed.”语篇导读：本文是一篇记叙文。
2020 年11 月21 日雅思考试真题机经及参考答案C The value of reefs in biodiverse (生物多样的) regions can be even higher. In parts of Indonesia and the Caribbean where tourism is the main use, reefs are estimated to be worth US$1 million per square kilometer, based on the cost of maintaining sandy beaches and the value of attracting snorkelers (浮潜者)and scuba divers (水肺潜水). Meanwhile, a recent study of the Great Barrier Reef in Australia found that the reef is worth more to the country as an intact ecosystem than an extractive reserve for fishing. Each year more than 1.8 million tourists visit the reef, spending an estimated AU$4.3 billion (Australian dollars) on reef-related industries from diving to boat rental to posh island resort stays. In the Caribbean, says UNEP, the net annual benefits from diver tourism was US$2 billion in 2000 with US$625 million spent directly on diving on reefs. Further, reef tourism is important source of employment, especially for some of the world's poorest people. UNEP says that of the estimated 30 million small-scale fishers in the developing world, most are dependent to a greater or lesser extent on coral reefs. In the Philippines, for example, more than one million small-scale fishers depend directly on coral reefs for their livelihoods. The report estimates that reef fisheries (渔场) were worth between $15,000 and $150,000 per square kilometer a year, while fish caught for aquariums (水族馆) were worth $500 a kilogram against $6 for fish caught as food. The aquarium fish export industry supports around 50,000 people and generates some US$5.5 million a year in Sri Lanka along.D Unfortunately, coral reefs are dying around the world. In particular, coral mining, agricultural and urban runoff(入水), pollution (organic and inorganic), disease, and the digging of canals and access into islands and bays are localized threats to coral ecosystems(生态系统). Broader threats are sea temperature rise, sea level rise and pH changes from ocean acidification (酸化) , all associated with greenhouse gas emissions. Some current fishing practices are destructive and unsustainable. These include cyanide fishing, overfishing and blast fishing. Although cyanide (氰化物毒)fishing supplies live reef fish for the tropical aquarium market, most fish caught using this method are sold in restaurants, primarily in Asia, where live fish are prized for their freshness. To catch fish with cyanide, fishers dive down to the reef and squirt cyanide in coral crevices and on the fast-moving fish, to stun the fish making them easy to catch. Overfishing is another leading cause for coral reef degradation. Often, too many fish are taken from one reef to sustain a population in that area. Poor fishing practices, such as banging on the reef with sticks (muro-ami), destroy coral formations that normally function as fish habitat. In some instances, people fish with explosives (爆炸物) (blast fishing), which blast apart the surrounding coral.E Tourist resorts that empty their sewage directly into the water surrounding coral reefs contribute to coral reef degradation. Wastes kept in poorly maintained septic tanks can also leak into surrounding ground water, eventually seeping out to the reefs. Careless boating, diving, snorkeling and fishing can also damage coral reefs. Whenever people grab, kick, and walk on, or stir up sediment (沉淀物) in the reefs, they contribute to coral reef destruction. Corals are also harmed or killed when people drop anchors on them or when people collect coral.F To find answers for these problems, scientists and researchers study the various factors that impact reefs.

The man had put on a pair of odd shoes, one with a thick sole(鞋跟) and one with a thinsole. As he came out to the street , he felt very uncomfortable.Turning to his daughter , he said :Why should one of my legs be longer than the other one?”The daughter looked at her father’s legs and said ,Y ou have put on two odd shoes! When he heard this , the man was very happy and thought to himself: What a bright daughter I have got!” Then he asked his daughter to go back to the house and got him another pair of shoes.When the daughter went back to the house, all she could find was one shoes with thick sole and one with thin sole.Taking the shoes to show her father, she said ,It’s no use changing ! These shoes are also odd, one with a thick sole and one with a thin sole.The man listened and thought to himself :If can’t be helped. I might as well wear the ones I have on now. So they went for their walk.6. The man thought that his daughter was B. clever7.It was the that found the resson for it . B. daughter8. The daughter came back , bringing with her.B. a pair of odd shoes9. What do you think that the man should have done?C.He should have changed one of his shoes.10. What do you think of the man and his daunghter?D. Either of then was foolish enough.15Passage Two:Many people who work in London prefer to live outside it , and to go in to their offices or sc hools every day by train , car or bus , even though this means they have to get up early in the moring and reach home late in the evening .One advantage of living ourside London is that houses are cheaper . Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one’own.Then , in the country one can really get away from the noise and hurry of busy working lives. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh , clean air of the country .If one likes gardens , one can spend one’s free time digging, planting, watering and doing the hundred and one other jobs which are needed in a garden .Then ,when the flowers and vegetables comg up , one has got the reward together withthose who have shared the secret of Nature .Some people , however, take no interest in country things : for them, happiness lies in the town , with its cinemas and theatres ,beautiful shops and busy streets, dance-halls . Such people would feel that their life was not worth living if they had to live it ourside London. An occasional walk in one of the parks and a fortninght’s (two weeks ) visit to the sea every summer is all the country they want:the rest they are quite prepared to leave to those who are glad to get away from Longon every night.11. Which of the following statements is NOT true?B. All the people who work in London prefer to live in the country .12. With the same money needed for , one can buy a little house with a garden in the country . C. renting a small flat without a garden13. When the garden is in blossom, that one has been rewarded.B. having spent time working in the garden14. People who think happiness lies in the city life would feel that if they had to live outside LondonA. their life was meaningless15. The underlined phrase get away from in the 3rd paragraph refdrs toC escape from16Passage one :Pearl Carlson was shaken awake at 3:30 a.m.. by a forceful pull. King, the family dog, was trying to pull her out of the bed. Then she smelled smoke and heard the sound of fire from her parent’s room. Pearl’s screams awaked her mother, Fern, and father, Howard, who had recently been in hospital for lung disease. Helping Howard to a first-floor window, Fern told him to clinb out , then ran to her daughter.Still inside, King appeared at pearl’s window, making squeaking(短促尖叫)sounds. When running toward pearl’s bedroom, Fern realized her husband hadn’t yet escaped. She made her way back through the smoke and flames, following king’s sound to where Howard lay semiconscious (半昏迷)on the floor. Fern helped him get outside. King came out only after both were safe.As day dawned, the carlsons saw that king’s paws were badly burnt, and his entire body was burnt, too. His chain collar had gotten so hot that it burnt his throat, making it impossible for him to bark(叫)normally. Only after the seven-year-old dog refused food did they find pieces of wood in his mouth and realize that king .who slept outside, had bitten through a wood door to warn his family.6. who was king in the story? C The family dog7.According to the story, the first one who was completely out of danger could be D. Pearl8.When the master’s room caught fire , B the dog waked pearl up9. After reading this story ,we’ve learnt that the following statements could be reasonable exceptB. the dog awoke mother first10.From this story it can be inferred that______ D. the dog is man’s best friendPassage Two:What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist .you will probably agree that knowing how to use a tool is important to a carpenter. Y ou will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist ,however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his11. What makes a scientist according to the passage?____ B The way he uses his tools12. “The scientist, however, goes one step further…”. The author says this to show____C the difference between scientists and ordinary people13. A sound scientific theory should be one that _______ A works not only under one set of conditions at one time, but also under the same conditions at other times1714.The author quotes the case of Albert Einstein to illustrate________ C that the investigations are important in science15. What is the main idea of the passage?________D Exactness and ways of using tools are the keys to the making of a scientist二．阅读理解Passage one:Mr perkin stood at the bus-stop and watched the cars go by. Many of the cars were new Beta 400s, and most of them were yellow. Mr perkin always wore the same clothes as other men ,ate the same food as other people, and did the same things after work ,and at the end of the week ,Mr perkin did not like to be different.The following week, Mr perkin bought a new, bright yellow Beta 400s. He was satisfied withit, and drove to work in it the very nest day. He was even more satisfied with his new car ,when he saw all the other Beta 400s,in front, behind ,and on both sides of him.Mr perkin parked his car in a big car-park near his office, and walked the rest of the way. But when he came back at five o’clock, there were so many bright yellow Beta 400s in the car-park that he did not know which car was his .He tried his key in some of the cars ,but people passing by gave him a look he didn’t like. So he stopped.Poor Mr perkin had to wait nearly two hours until his was the only yellow Beta 400s in the car-park.6. Mr perkin wanted a new yellow Beta 400s because_______ C he liked to do the same as other people7. He drove to work in his new car _______ A the very nest day8.

While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer of laborer of some sort.This attitude toward manual(体力的)labor is now still seen in many aspects of American life. One is invited to dinner at a home that is not only comfortably but even luxuriously(豪华地) furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward, furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery . On the contrary, the hostess usually takes pride in careful preparation of special dishes. A professional may talk about washing the car, digging in his flowerbeds, painting the house. His wife may even help with these things, just as he often helps her with the dishwashing. The son who is away at college may wait on table and washdishes for his living ,or during the summer he may work with a construction gang on a highway in order to pay for his education.11. From paragraph 1, we know that in America _________A people tend to have a high opinion of the self-made man12.according to the passage, the hostess cooks dinner herself mainly because_______B she takes pride in what she can do herself13.The expression” wait on table ”in the second paragraph means___________D serve customers in a restaurant14.The author’s attitude towards manual(体力的)labor is _________ A positive15.Which of the following may serve as the best title of the passage?____________B American attitude toward manual labor二；阅读理解Passage one:In England, people often talk about the weather because they can experience four seasons in one day. In the morning the weather is warm just like in spring . an hour later black clouds come and then it rains hard. The weather gets a little cold . in the late afternoon the sky will be sunny, the sun will begin to shine, and it will be summer at this time of a day.In England, people can also have summer in winter, or have winter in summer. So in winter they can swim sometimes, and in summer sometimes they should take warm clothes.When you go to England, you will see that some English people usually take an umbrella or a raincoat with them in the sunny morning, but you should not laugh at them.If you don’t take an umbrella or a raincoat, you will regret later in the day.6. why do people in England often talk about the weather?A because they may have four seasons in one day.197.

Am I wearing unattractive clothes?It is obvious that such uncomfortable feelings must negatively affect people. A person’s conception of himself or herself is reflected in the way he or she behaves, and the way a person。

It emits light in the visible region of the spectrum (400 – 700 nm). The radiation power is less than 1 mW. Provided that the instrument is used in accord-ance with the instructions, safe operation is ensured.In schools and other places of education or training, the instrument must only be used under the supervision of a trained and respon-sible person.Do not look into the light beam - that is not necessary when using the sensor.∙ If the housing of the instrument showsvisible signs of damage, it must be taken out of use immediately. ∙ Do not use any optical equipment that nar-rows the light beam. ∙Do not open the instrument housing.The instrument emits a laser beam at 630 nm wavelength and measures the reflected light. Two sensitivity ranges (near zone and distant zone) are provided, to adjust the instrument parameters for different operating conditions. The near-zone setting adjusts the instrument pa-rameters for operating distances of 5 to 50 mm. The experiment should be chosen so that there are widely different reflectivities (e.g. matt black markings on a white or diffusely reflecting background). With reflecting foils or microprism mirrors, a larger fraction of the light is reflected in the incident direction, and one can then work with a beam box up to 5 m long without special adjustments to the mirror. In such cases one should use the distant-zone setting.By connecting the instrument to other external technical aids, one can measure physical quantities related to the motions of bodies, such as rate of rotation, angle of rotation, an-3B Scientific GmbH ▪ Rudorffweg 8 ▪ 21031 Hamburg ▪ Germany ▪ Subject to technical amendments © Copyright 2018 3B Scientific GmbHgular acceleration, distance travelled, velocity and linear acceleration.The sensor is compatible with the VinciLab (1021477), the €Lab (1021478) and the digital counter (1001032 or 1001033).
