Cooke turned and hardly had time to react before a flying disc hit her in the face with a "big bang”, leaving her right cheek swollen almost to the size of a golfball.Two men playing disc golf at the course in Jellie Park were about 20 metres fromthe pairwhen one of them threw the disc hard, aiming for a nearby goal.After being hit Cooke immediately went to the emergency department, where two CT scans on her face and cheek found she had escaped any broken bones. "I'm lucky it didn't hit my eye because I think I would have lost it." Cooke said.Cooke often walks her dog at the park and said it was always busy with people playing disc golf, but it was not until after Tuesday that she became concerned about public safety there.There were no signs about the disc golf course in the park, she said, and the area is shared with children and people walking their dogs.“If it had hit one of the kids in the head, it could have killed them.” Cooke did not think she was the only person who had been hit before, and said there would be others who share her concerns.Cooke planned to go to the council, saying it needed to realise how dangerous it was for the space to be shared by everyone and to provide disc golfers with a space where they can play safely. "There should be rules about how it's done, making it safe for everyone.”4. What happened to Cooke on Tuesday?A. She was struck by a golf ball.B. She was hit by a flying disc.C. She was beaten by two men.D. She was frightened by a mad dog.5. What do the underlined words "the pair" in Paragraph 2 refer to?A. Cooke and her friend.B. Cooke and her dog.C. The two disc golfers.D.

To get the two men in trouble.B. To call for a ban on disc golf.C. To ask for personal protection.D. To call for safer places for disc golf.CJapan is known to have higher than average rates of stomach cancer. Recently, the town of Kaneyama in Yamagata Prefecture decided to get its 6, 000 residents (居民) tested.However, the frozen urine samples (尿样) are not tested in conventional ways. Instead, Professor Masao Miyashita and his team are using them in a trial to determine if specially trained cancer-sniffing dogs can accurately detect the disease. Though the study is still in its early stages, Miyashita is thrilled with the results. He said, “In our research so far, cancer detection dogs have been able to find signs of cancer with an accuracy of nearly 100 percent.”Researchers have known about the animals’ superior sensory skills for decades. However, their ability to detect cancer in humans came to light in 1989, after a dog sniffed out early-stage malignant melanoma (恶性黑色素瘤) on a patient’s leg in London. Since then, scientists from many countries have conducted studies to test dogs’ great skill at identifying cancer chemicals.While most dogs can be trained for the task researchers say the best candidates are dogs that are precise, quiet, and perhaps even a little shy. The training process is similar to how dogs are taught to learn any trick — by rewarding them with treats! However, it takes much longer because the dogs have to learn to separate the “cancer scent (气味)”from the thousands of organic compounds (有机化合物) in the human body. Researchers begin by exposing the dogs to urine samples from people with cancer, people with other diseases, and patients with no health issues, Once the dogs are able to accurately identify cancer, they are further trained to detect particular kinds of cancer.Successful as they may be, experts think dogs are unlikely to replace conventional tests. For one, it takes about seven years and costs as much as $45,000 to train a single dog. Klaus Hackner, a researcher and physician who studies dogs detecting cancer in breath samples at Krems University Hospital in Austria, is also not convinced dogs can be relied upon alone. Patients, therefore, have to receive further tests to confirm if they have the8. What do we know about the cancer-sniffing dogs mentioned in Paragraph 2?A. They have done a great job.B. They are trained in a special way.C. They can easily learn to distinguish cancer.D. They can be seen in many Japanese hospitals.9. What does the author intend to do in Paragraph 3?A. Offer readers some advice.B. Add some background information.C. Summarize the previous paragraphs.D. Introduce a new topic for discussion.10. What kind of dog is suitable for the cancer-sniffing job?A. Smart and brave.B. Active and faithful.C. Strong and patient.D. Careful and peaceful.11. What is Klaus Hackner’s opinion on cancer-sniffing dogs?A. They should work as a team.B. They need to receive more training.C. They can replace doctors in detecting cancer.D. They should be used together with traditional tests.DWe use what is known as inner speech, where we talk to ourselves, to evaluate situations and make decisions. Now, a robot has been trained to speak aloud its inner decision-making process, giving us a view of how it responds to contradictory demands.Arianna Pipitone and Antonio Chella at the University of Palermo, Italy, programmed a humanoid robot named Pepper, with software that models human cognitive(认知的)processes, which allowed Pepper to retrieve (检索)relevant information from its memory and find the correct way to act based on human commands, as well as a text — to — speech processor. It allowed Pepper to voice its decision-making process while completing a task, "With inner speech, we can better understand what the robot wants to do and what its plan is," says Chella.The researchers asked Pepper to set a dinner table according to etiquette (礼仪)rules they had programmed into the robot. Inner speech was either enabled or disabled to see how it affected Pepper's ability to do what wasWhen instructed to place a napkin on a fork with its inner speech enabled, Pepper asked itself what the etiquette required and concluded that this request went against the rules it had been given. It then asked the researchers if putting the napkin on the fork was the correct action. When told it was, Pepper said, "OK, I prefer to follow your desire," and explained how it was going to place the napkin on the fork.When asked to do the same task with inner speech disabled, Pepper knew this contradicted etiquette rules, so it didn't perform the task or explain why.With the potential for robots to become more common in the future, this type of programming could help the public understand their abilities and limitations, says Sarah Sebo at theUniversityofChicago. "It maintains people's trust and enables cooperation and interactions between humans and robots," she says. However, this experiment only used a single human participant, says Sebo. "It's unclear how their approach would compare across a wide range of human participants," she says.12. Why does the author mention how people make decisions in the first paragraph?A. To introduce the topic.B. To make comparisons.C. To provide an example.D. To support his argument.13. How did Pepper react to the contradictory instruction with its inner speech enabled?A. It failed to complete the task.B. It followed the etiquette rules.C. It made a random decision.D. It communicated with the researchers.14. What did Sarah Sebo think of the research?A. It was creative but worthless.B. It was a good try but the result was a failure.C. It was inspiring but needed further evidence.D. It was carefully designed but poorly performed.15. Which of the following is the best title for the text?A. Robot Taught To Be PoliteB. Robot Can Explain Its DecisionC. Robot Making Decisions: No Longer A DreamD. Robot-Human Communication: No Longer A Problem第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

The passage most probably appeals to those who are .A. planning a business tripB. seeking a weekend getawayC. fond of online shoppingD. interested in geography studyBThe new garbage sorting regulation has taken effect in Shanghai starting July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to clarify the new rules.The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, hazardous (有害的) waste, household food waste and residual (剩余的) waste. Hazardous waste, as the name suggests, includes assorted poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides. Household food waste, which is translated to “wet trash” in Chinese，refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers. Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste. The definition of residual waste is a little confusing. Anything that is not listed above belongs in this category.As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own ways to sort trash.“We should do this from a pig’s angle,” commented one netizen. “Those edible (可食用的) for pigs are household food waste. Those even pigs don’t want to eat are residual waste. If a pig consumes something and dies of it, then something must be hazardous waste. Those which can be sold and the money we gain can be used to purchase pigs are recyclable waste.” The new regulation has gone into effect on July 1. Those who do not sort their trash properly will be fined RMB200.24. What do the old thrown-away sweaters belong to?A. Residual waste.B. Hazardous waste.C. Recyclable waste.D. Household food waste.25. What does “wet trash” have in common?A. They are completely wet.B. They all come from plants.C. They can give off bad smell.D. They can break up easily.26. What is the tone of the netizen?A. Humorous.B. Serious.C. Delightful.D. Uncertain.27. What is the main idea of the text?A. Shanghai bans four sorts of garbage.B. Shanghai launches garbage sorting enforcement.C. Citizens in Shanghai still question garbage sorting.D. Citizens in Shanghai welcome the garbage sorting policy.CIn the old days, when you had to drive to a movie theater of to to a video store toget some entertainment, it was easy to see how your actions could have an impact om the environment.You were hopping into your war, driving across town and coughing out emissions（排放）and using gas all the way.But now that we’re used to staying at home and streaming movies, we might get a little cocky. After all ,we’re just picking up our phones or maybe turning on the TV. You’re welcome.Mother Nature.Not so fast, says a recent report from the French-based Shit Project. Watching a half-hour show would lead to 3.5 pounds of CO2 emissions. That’s like driving 3.9 miles. According to "Climate Crisis: The Unsustainable Use of Online Video," digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Stored in data centers, videos are transferred to our terminals such as computers, smart phones, etc. via networks: all these processes require electricity whose production consumes resources and usually involves CO2 emissions.In the European Union, the Eureca project lead scientist, Rabih Bashroush, calculated that 5 billion downloads and streams of the song "Despacito" consumed as much electricity as the countries of Chad, Guinea-Bissau, Somalia, Sierra Leone and the Central African Republic used in a single year.Streaming is only expected to increase as we become more attached to our devices. Online video use is expected to account for 80%of all internet traffic by 2022 according to CISCO. By then, about 60% of the world's population will be online. You're probably not going to give up your streaming services, but there are things you con do to help lessen the impact of your online use.Here are some tips:※Disable autoplay for video on social media.※Stream over Wi-Fi, not mobile networks.※Watch on the smallest screen you can.※Don’t use high-definition（高清）video on devices.28.It can be inferred from paragraph 2 that people think .A.they should welcome Mother NatureB.watching movies at home is more funC.it is inconvenient to drive to a movie theaterD.streaming at home avoids possible emissions29.We may learn from the text that .A.3.9 miles may produce 3.5 pounds of CO2B.digital technologies account for 4% of electricity useC.Online video use makes up 80% of all internet trafficD.60% of the world’s population watch videos online30.Why are the five countries mentioned in paragraph 4?A.To praise their energy-efficient practice.B.To prove the poverty of the five countriesC.To stress the popularity of the song “Despacito”D.To show the high energy use of downloads and streams31.How can people help to save energy when streaming?e high-definition videos.B. Turn off video autoplayC. Stream over mobile networks.D. Watch movies on bigger screens.DAs they reach school age, about 90 percent of children will have experienced a condition in which fluid (液体) fills the middle ear, muffling (使模糊) sound and sometimes causing infection. The fluid usually clears on its own, but if not, it can lead to a painful ear infection called acute otitis (中耳炎) media. In some cases the fluid can persist for more than a year, causing hearing loss during this period, and slowing down their development of language and social skills.Diagnosis usually requires a visit to a specialist—but researchers have now developed an app that detects this fluid just as accurately, with only a smartphone and a paper funnel (漏斗).Doctors typically detect the problem by peering into the ear for a visual assessment. Yet, this method has only a 50 percent accuracy rate. “Right now, if you bring your child to a pediatrician, or to any urgent care family doctor, the way they look at whether or not there’s fluid in the middle ear is by looking at the eardrum,” says Sharat Raju, a surgeon in the department of head and neck surgery at the University of Washington.For a cheaper and more accessible alternative, researchers at the University of Washington turned to smartphones. First the user follows a template to cut and tape a piece of paper into a funnel, which can be placed between a smartphone and the patient’s ear. Next the app plays a chirping sound through the phone’s speaker; the sound waves bounce off the eardrum and hit the phone’s microphone, where they register and are analyzed by the app. An eardrum with fluid behind it will vibrate (振动) differently than if the middle ear is full of air, as it normally is.To develop the app, the researchers first played chirps for patients with and without fluid in their ears. They recorded the echoes (回音), which indicate the eardrum’s mobility. Then they used a machine learning model to classify the returning sound waves, determining which audio characteristics indicated a normal ear and which suggested the presence of fluid. Once they tested the app on 98 children, ranging from 18 months to 17 years old, at Seattle Children’s Hospital. It correctly detected fluid in 85 percent of cases, and correctly identified fluid-free ears in 82 percent. The researchers are currently trying to get FDA approval for the app, and have founded a company to commercialize it. They hope to make it available by the end of the year, to help parents track children’s ear health at home.32. What do we know about the fluid from the first paragraph?A. It is mostly part of children’s growth.B. It is unavoidable for any child.C. It is a permanent physical condition.D. It is beyond any medical means.33. What does the underlined word “pediatrician” refer to in Paragraph 3?A. A hospital.B. A specialist.C. A relative.D. An app.34. What is the fourth paragraph mainly about?A. The application of the app.B. The causes of the kid’s ear problem.C. The purpose of developing the app.D. The experiment of the smartphone.35. What do the researchers expect of the app?A. It will upgrade the medical technology.B. It will hit the market in the near future.C. It will help children do better academically.D. It will save doctors medical operations.第二节(共5小题:每小题3分，满分15分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

2020年大同市第四中学高三英语三模试题及答案
2020年大同市第四中学高三英语三模试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ASpeaking with people on the phone is pretty rare these days. Most people use e-mail or messaging apps when they need to communicate with someone. Sometimes, though, making a call is unavoidable. This simple act can actually be a nightmare for some people. Their hearts race and their hands sweat at the very thought. If this sounds familiar to you, you might be one of the millions of people who suffer from telephobia—the fear of speaking over the phone.Telephobia is a form of social anxiety, although people who feel perfectly comfortable in social situations may also experience telephobia. When speaking face-to-face, we give off lots of facial or bodily cues that help each other follow the conversation. This is not the case over the phone. And the idea of speaking into this void（真空）makes people terrified that they will freeze up, stumble over their words（失言）, or lose control of the conversation and look foolish In fact, telephobia is very similar to thefear people feel before putting on a performance in front of a big audience. However, there are things that one suffering from thin condition can do to reduce this fear and make phone calls at least somewhat bearable.One thing that those with telephobia can do before a call in smile. It may sound silly, but smiling before doing something stressful can help you feel more relaxed. It won't delete the anxiety altogether, but it will take the edge off it.Similarly, imagining how the call will go before you make it can also help things go more smoothly. Running through a positive conversation in your head will make you feel less nervous and may help you predict any possible problems. There's no need to spend hours on this, just a few minutes thinking up a general idea of what you want to say. You can even write down some brief notes to remind yourself of your talking points. This is particularly useful for dealing with the fear of not being able to express yourself naturally.And finally, when faced with receiving a call, you don't always have to pick up. There's nothing wrong with calling the person back later when you feel more comfortable.So the next time your phone starts ringing, remember—speaking on the phone doesn't have to make you sweat. The important thing is to be aware of your fear and take steps to deal with it.1. According to the article, which situation can cause a feeling similar lo telephobia?A.Speaking face-to-face to a good friend.B. Performing in front of a large audience.C. Running in a race without proper shoes.D. Using a messaging app while on the subway.2. Which of the following is NOT mentioned as a way to deal with telephobia?A.Imagining how the call will go before you make it.B. Standing on the edge of a tall building while making a call.C. Calling someone back later instead of answering their phone calls right away.D. Writing down some brief notes to remind yourself of your talking points.3. What is the main purpose of the passage?A. To present ways to ease telephobia.B. To explain the development of telephobiaC. To introduce the influence of telephobia.D. To give the reason why someone suffers from telephobia.BAs an old saying inChinagoes, “The days of the Sanjiu periodare the coldest days.” “Sanjiu period” , which is in Minor Cold, refers to the third nine-day period (the l9th to the 27th day) after the day of the Winter Solstice(冬至). There are many different customs related to Minor Cold inChina.Eating hotpotDuringMinor Cold people should eat some hot food to benefit the body and defend against the cold weather. Winter is the best time to have hotpot and braised mutton with soy sauce. But it is important to notice that too much spicy food may cause health problems.Eating huangyacaiInTianjin, there is a custom to have huangyacai, a kind of Chinese cabbage, during Minor Cold. There are large amounts of vitamins A and B in huangyacai. As huangyacai is fresh and tender, it is fit for frying, roasting and braising.Eating glutinous rice (糯米饭)According to tradition, the Cantonese eat glutinous rice in the morning during Minor Cold. Cantonese people add some fried preserved pork, sausages and peanuts and mix them into the rice.Eating vegetable riceIn ancient times, people inNanjingtook Minor Cold quite seriously, but as time went by, the celebration of Minor Cold gradually disappeared. However, the custom of eating vegetable rice is still followed today. The rice is steamed and is unspeakably delicious. Among the ingredients (原料), aijiaohuang (a kind of green vegetable), sausages and salted duck are the specialties in Nanjing.4. What do we know about Minor Cold?A. It refers to the Winter Solstice.B. The Sanjiu period is in this period.C. It lasts twenty-seven days.D. It marks the first day of winter.5. What is a special custom in Tianjin in Minor Cold？A. Eating hotpot.B. Having vitamin A and B pills.C. Having huangyacai.D. Buying cabbage.6. How do the Cantonese eat glutinous rice?A. They fry and toast it.B. They eatit for dinner.C. They mix it with many other things.D. They steam it with soy sauce.7. This text may be taken from the ________ column (栏目) of a newspaper.A. travelB. cultureC. fashionD. scienceCGetting drunk on ice cream used to be the stuff of dreams, but thanks to Will Rogers, inventor and owner of WDS Dessert Stations in Hinkley, Illinois, it has become a delicious reality. The Below Zero icecream machine uses a unique technique to freeze alcohol, which allows you to turn beers, cocktails and even spirits (烈酒) into delicious soft —serve ice cream.Rogers was trying to create a highly — caffeinated espresso ice cream flavor when he realized hecould use the same technique with alcoholic beverages. He started experimenting with various gums and stabilizers commonly used in the ice cream industry and eventually patented something called the NEA gel. It’s this magical concoction (调制品) that allows the alcohol to freeze to a near solid inside the Below Zero ice cream machine.Even though Below Zero changes the texture (质地) of beer, cocktails and even spirits, essentially turning them into soft —serve ice cream, it does not affect the alcohol contentat all. The ABV (酒精度) remains exactlythe same, which means you can get drunk on ice — cream just as you would on the same concoctions in liquid form.Will Rogers claims that it takes around 30 minutes for beer to go from liquid to ice cream form, but higher alcohol content drinks take longer. Essentially, the higher the alcohol level, the longer the wait.The American inventor plans to sell Below Zero ice cream machines to bars and breweries wanting to surprise their patrons. Metro reports that machines will sell for about 6,000.8. What’s the name of the machine which can change beer and spirits into ice cream?A. Will RogersB. WDS Dessert StationsC. HinkleyD. Below Zero9. What makes alcohol to freeze to a near solid inside the machine?A. gums.B. stabilizers.C. NEA gel.D. ABV.10. What can we know from the passage?A. The machine can change all liquids into ice cream.B. It takes 20 minutes for beer to change into ice cream.C. The higher the alcohol level, the shorter the wait will be.D. The machine changes the texture of beer, cocktails and even spirits.11. What can we infer from the passage?A. The machine affects the alcohol content.B. You can get drunk if you have ice—creams made from spirits.C. The American inventor doesn’t want to sell themagical machine.D. Bars and breweries will not become potential buyers of the machine.DConcrete is the world's most consumed material after water. Because it already surrounds us in the built environment, researchers have been exploring the idea of using concrete to store electricity—turning buildings into giant batteries. The idea has been gaining ground as we have come to increasingly rely on renewable energy from the wind and sun: rechargeable batteries are necessary when the breeze dies down or darkness falls.Experimental concrete batteries have only managed to hold a small part of what a traditional battery does. But one team now reports in Buildings that it has developed a rechargeable original model that could represent a more than 900 percent increase in stored charge, compared with earlier attempts.A live-in concrete battery might sound unlikely. Still, "you can make a battery out of a potato," notes AimeeByrne. In a future where sustainability is key, she likes the idea of buildings that avoid waste by providing shelter and powering electronics.Although the new design stores more than 10 times as much power as earlier attempts, it still has a long way to go: 200 square meters of it "can provide about 8 percent of the daily electricity consumption" of a typical U.S. home, Zhang says.This is not enough to compete with today's rechargeable devices. "We're getting milliamps (毫安) out of concrete batteries—we're not getting amps (安培), "Byrne says." We're getting hours as opposed to days of charge." But she adds that" concrete batteries are completely in their childhood, compared to other battery designs." The earliest batteries were simple andbulky. Researchers experimented with new materials and designs for more than a century to develop today's small devices. Byrne suggests concrete-based energy storage could undergo a similar evolution. "The whole idea is that we're looking far into the future," she says. "We're playing the long game with it."12. What can we learn about the concrete batteries?A. They become increasingly renewable.B. They are the most consumed batteries.C. They are being developed by researchers.D. They will replace energy from the wind and sun.13. Why does Byrne mention a battery out of a potato?A. To show it is easy to build concrete batteries.B. To argue it is possible to develop concrete batteries.C. To make her statement more interesting.D. To call on people to protect the environment.14. What does the underlined word "bulky" in Paragraph 5 mean?A. HeavyB. CheapC. EfficientD. Small.15. What doesByrne think of concrete batteries?A. They beat today's rechargeable devices.B. They are simple and bulky.C. They have a doubtful future.D. They have a long way to go.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

The passage most probably appeals to those who are .A. planning a business tripB. seeking a weekend getawayC. fond of online shoppingD. interested in geography studyBThe new garbage sorting regulation has taken effect in Shanghai starting July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to clarify the new rules.The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, hazardous (有害的) waste, household food waste and residual (剩余的) waste.Hazardous waste, as the name suggests, includes assorted poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides.Household food waste, which is translated to “wet trash” in Chinese，refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers.Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste.The definition of residual waste is a little confusing. Anything that is not listed above belongs in this category.As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own ways to sort trash.“We should do this from a pig’s angle,” commented one netizen. “Those edible (可食用的) for pigs are household food waste. Those even pigs don’t want to eat are residual waste. If a pig consumes something and dies of it, then something must be hazardous waste. Those which can be sold and the money we gain can be used to purchase pigs are recyclable waste.” The new regulation has gone into effect on July 1. Those who do not sort their trash properly will be fined RMB200.24. What do the old thrown-away sweaters belong to?A. Residual waste.B. Hazardous waste.C. Recyclable waste.D. Household food waste.25. What does “wet trash” have in common?A. They are completely wet.B. They all come from plants.C. They can give off bad smell.D. They can break up easily.26. What is the tone of the netizen?A. Humorous.B. Serious.C. Delightful.D. Uncertain.27. What is the main idea of the text?A. Shanghai bans four sorts of garbage.B. Shanghai launches garbage sorting enforcement.C. Citizens in Shanghai still question garbage sorting.D. Citizens in Shanghai welcome the garbage sorting policy.CIn the old days, when you had to drive to a movie theater of to to a video store to get some entertainment, it was easy to see how your actions could have an impact om the environment.You were hopping into your war, driving across town and coughing out emissions（排放）and using gas all the way.But now that we’re used to staying at home and streaming movies, we might get a little cocky. After all ,we’re just picking up our phones or maybe turning on the TV. You’re welcome.Mother Nature. Not so fast, says a recent report from the French-based Shit Project. Watching a half-hour show would lead to 3.5 pounds of CO2 emissions. That’s like driving 3.9 miles. According to "Climate Crisis: The Unsustainable Use of Online Video," digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Stored in data centers, videos are transferred to our terminals such as computers, smart phones, etc. via networks: all these processes require electricity whose production consumes resources and usually involves CO2 emissions.In the European Union, the Eureca project lead scientist, Rabih Bashroush, calculated that 5 billion downloads and streams of the song "Despacito" consumed as much electricity as the countries of Chad, Guinea-Bissau, Somalia, Sierra Leone and the Central African Republic used in a single year. Streaming is only expected to increase as we become more attached to our devices. Online video use is expected to account for 80%of all internet traffic by 2022 according to CISCO. By then, about 60% of the world's population will be online.You're probably not going to give up your streaming services, but there are things you con do to help lessen the impact of your online use.Here are some tips:※Disable autoplay for video on social media.※Stream over Wi-Fi, not mobile networks.※Watch on the smallest screen you can.※Don’t use high-definition（高清）video on devices.28.It can be inferred from paragraph 2 that people think .A.they should welcome Mother NatureB.watching movies at home is more funC.it is inconvenient to drive to a movie theaterD.streaming at home avoids possible emissions29.We may learn from the text that .A.3.9 miles may produce 3.5 pounds of CO2B.digital technologies account for 4% of electricity useC.Online video use makes up 80% of all internet trafficD.60% of the world’s population watch videos online30.Why are the five countries mentioned in paragraph 4?A.To praise their energy-efficient practice.B.To prove the poverty of the five countriesC.To stress the popularity of the song “Despacito”D.To show the high energy use of downloads and streams31.How can people help to save energy when streaming?e high-definition videos.B. Turn off video autoplayC. Stream over mobile networks.D. Watch movies on bigger screens.DAs they reach school age, about 90 percent of children will have experienced a condition in which fluid (液体) fills the middle ear, muffling (使模糊) sound and sometimes causing infection. The fluid usually clears on its own, but if not, it can lead to a painful ear infection called acute otitis (中耳炎) media. In some cases the fluid can persist for more than a year, causing hearing loss during this period, and slowing down their development of language and social skills.Diagnosis usually requires a visit to a specialist—but researchers have now developed an app that detects this fluid just as accurately, with only a smartphone and a paper funnel (漏斗).Doctors typically detect the problem by peering into the ear for a visual assessment. Yet, this method has only a 50 percent accuracy rate. “Right now, if you bring your child to a pediatrician, or to anyurgent care family doctor, the way they look at whether or not there’s fluid in the middle ear is by looking at the eardrum,” says Sharat Raju, a surgeon in the de partment of head and neck surgery at the University of Washington.For a cheaper and more accessible alternative, researchers at the University of Washington turned to smartphones. First the user follows a template to cut and tape a piece of paper into a funnel, which can be placed between a smartphone and the patient’s ear. Next the app plays a chirping sound through the phon e’s speaker; the sound waves bounce off the eardrum and hit the phone’s microphone, where they register and are analyzed by the app. An eardrum with fluid behind it will vibrate (振动) differently than if the middle ear is full of air, as it normally is.To develop the app, the researchers first played chirps for patients with and without fluid in their ears. They recorded the echoes (回音), which indicate the eardrum’s mobility. Then they used a machine learning model to classify the returning sound waves, determining which audio characteristics indicated a normal ear and which suggested the presence of fluid. Once they tested the app on 98 children, ranging from 18 months to 17 years old, at Seattle Children’s Hospital. It correctly detected fluid in 85 percent of cases, and correctly identified fluid-free ears in 82 percent.The researchers are currently trying to get FDA approval for the app, and have founded a company to commercialize it. They hope to make it available by the end of the year, to help parents track children’s ear health at home.32. What do we know about the fluid from the first paragraph?A. It is mostly part of childr en’s growth.B. It is unavoidable for any child.C. It is a permanent physical condition.D. It is beyond any medical means.33. What does the underlined word “pediatrician” refer to in Paragraph 3?A. A hospital.B. A specialist.C. A relative.D. An app.34. What is the fourth paragraph mainly about?A. The application of the app.B. The causes of the kid’s ear problem.C. The purpose of developing the app.D. The experiment of the smartphone.35. What do the researchers expect of the app?A. It will upgrade the medical technology.B. It will hit the market in the near future.C. It will help children do better academically.D. It will save doctors medical operations.第二节(共5小题:每小题3分，满分15分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

There was not one night that I don’t remember mom reading me a storybook by my bedside. I was extremely inspired by the wonderful way the words sounded.I always wanted to know what my mom was reading. Hearing mom say, “I can’t believe what’s printed in the newspaper this morning,” made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said, “The C-A-N-D-Y is hidden on the top shelf,” I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A’s on my tests. Sometimes, I would read a novel that was assigned, but I didn’t enjoy this type of reading.I liked facts, things that are concrete. I thought anything abstract left too much room for argument.Now that I’m growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don’t have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.We’re taught to read because it’s necessary for much of human understanding. Reading is an important partof my life. Reading satisfies my desire to keep learning. And I’ve found that the possibilities that lie within books are limitless.4. Why did the author want to grab the newspaper out of mom’s hands？A. She wanted mom to read the news to her.B. She couldn’t wait to tear the newspaper apart.C. She couldn’t help but stopmom from reading.D. She was eager to know what had happened.5. According to Paragraph 3, the author’s reading of road signs shows___________.A. her own way to find herselfB. her eagerness to develop her reading abilityC. her growing desire to know the world around herD. her effort to remind mom to obey traffic rules6. The author takes novel reading as a way to___________.A. explore a mysterious landB. develop an interest in learningC. get away from a confusing worldD. learn about the adult world7. What could be the best title for the passage？A The Pleasure of Reading B. Growing Up with ReadingC. The Magic of ReadingD. Reading Makes a Full ManCThe idea of growing food in a desert would make most people laugh but this is quickly becoming a reality. There are currently two desert farms in the world where quality vegetables are being planted cheaply and easily.Sundrop Farms, based in South Australia, uses experimental greenhouses to grow tomatoes, peppers and cucumbers. The biggest challenge of growing food in a desert, obviously, is the lack of available water. The researchers at Sundrop Farms have gotten aroundthis problemby using the sun to desalinate (淡化) sea water. It can also be used to control the temperature of the greenhouses.Without depending on limited resources such as land and fresh water Sundrop Farms has made farming a practice. This can increase the world’s food supplies. Another benefit ofthis kind of farming is that it can be done anywhere, thus reducing the costs of transporting food to distant locations. Yet another benefit is that it reducesthe need for pesticides (杀虫剂).Another experimental desert farm is the Sahara Forest Project, which began in Qatar in December 2012. Greenhouses in the farm are cooled by saltwater. Solar power and other technologies are used together to help make vegetation (植被) grow in the desert environment. As deserts have expanded over recent years around the world due to global warming, this project could solve the problem.The result form the Qatar project were better than expected and in June of 2014, Jordan agreed to host another one. This will be much bigger than the Qatar project and the project members will have even more opportunities to test their experiments on a much larger scale. It is not clear yet that desert farming resents the future of farming but these projects have shown some success in the field.8. What does “this problem” in paragraph 2 refer to?A. Sea water is bard to purify.B. The desert is short of water.C. The temperature is high in the desert.D. Desert farms aren’t fit to plant vegetables.9. What is one of the characters of desert farming?A. It needs more pesticides.B. It saves delivery costs.C. It has a location limit.D. It solves food waste problems10. What can we know about the Sabara Forest Project?A. It lives up to expectationsB. It can help produce more foodC. It is started to prevent global warmingD. It uses technology to produce saltwater11. What can be inferred about desert farming from the last paragraph?A. It still has problems to solve.B. It represents the future of farming.C. Its early success has aroused interest in it.D. Its aim is to create more job opportunities.DAs COVID-19 spread through Japan last spring, a doctor despaired. What shocked him was not the pace of infection, or a lack of protective equipment, but the old systems used to record test results and so track the courseof the epidemic. “Even with coronavirus, we're handwriting and faxing,” he complained on Twitter.Japan has excellent health care. Life expectancy at birth is 85 years, the highest in the world. But doctors have been slow to embrace(欣然接受) the efficiencies of information technology, despite Japan's reputation for medical technology. The OECD ranks it last among its members for its management and use of data in health care.A commission of experts convened(召集) by the Asia-Pacific Initiative, a think-tank in Tokyo, declared Japan's response to COVID-19 a “digital defeat”。

AThere are more Starbucks special drinks than you could ever dream of, and we're talking about the items that maybe aren't offered at your local shop but are offered at one of the other approximately 30，000 locations around the world. Depending on what country you are in, the menu may look a little different, so if you're planning a trip anytime soon, check out what fun drinks you may find!Japan—Sakura Blossom Cream LatteThe drink is currently only available in Japan. Sakura, which means cherry blossom, is considered to be a symbol of regeneration and simplicity. It is the national flower of Japan, and Starbucks typically only has the drink available in the springtime.The drink itself is just pink, with sakura sauce, cherry blossom milk jelly, and strawberry sauce or jelly used to create the pink color. The drinks also come in special cherry blossom－themed cups.Vietnam—Dolce MistoStarbucks created the Dolce Misto spec ifically for the Vietnamese market. “It's designed to bring Vietnamese customers a new flavor and respect for traditional Vietnamese coffee，” said the general director of Starbucks Vietnam on its release in 2015.Dolce Misto is reportedly one of the strongest drinks in any Starbucks throughout the world. If sweet and strong is how you like your coffee and you live in Vietnam, this is the perfect Monday-afternoon pick-me-up for you.Chile—Lemon Bar FrappuccinoMeant to be the perfect sweet-and-sour summer drink, Starbucks Chile offered a Lemon Bar Frappuccino for the summer of 2018. With the combination of vanilla bean and lemonade topped with caramel sugar and whipped cream, the drink was relatively well received, though some were disappointed there was no coffee in it. It's still unknown whether Starbucks will be bringing the limited edition drink back to Chile or anywhere for the summer of 2019.1. When is Sakura Blossom Cream Latt e accessible to customers in Japan?A. October.B. July.C. December.D. April.2. What is special about Dolce Misto?A. It is available throughout the world.B. It helps open the Vietnamese market.C. It is a refreshing strong drink for customers.D. It is a traditional Vietnamese coffee drink.3. What may upset some people about Lemon Bar Frappuccino?A. It offers sweet－and－sour taste.B. It is a Starbucks drink withoutcoffee.C. It is one of the limited drinks in Chile.D. It is uncertain whether Starbucks will bring it back.B“I will need to open your neck to remove the tumor，” the surgeon told me on a hot summer day. The words turned into white noise. “So, an ugly scar across my neck, then? ” I asked. The nurse said: “Don't worry. The closure is like his signature. Just like you want a perfect scar, he wants to give you one. You'll barely see it.” I found some comfort in that.I googled “cancer surgery scar” and was presented with neck images: necks with red and purple lines, closed with stitches or glue; necks with mult iple scars… It was enough to make me shut my Macbook, as anxiety pulsed through my body. In the mirror, I admired my neck, running my finger across a gold chain I wore. Then a tiny voice said: “Mummy！”My then five-year-old son, Jack, appeared in the mirror behind me. Our reflection was a big reality check. See, my son didn't know I had cancer and was having surgery. I'm a single mom. Jack lives with me and doesn't have a relationship with his father. I'm his hero. I'm the homework helper, nurse, chef, taxi driver, and every other variation of parent. I knew I couldn't wimp-out over cancer or some scar on my neck—I'm this kid's life!So I did the next best thing I could think of: I made an appointment to get my hair done a few days before the first surgery. My goal was simple: golden hair to frame my scar. If I couldn't hide it, I might as well show it off. I never had any intentions of hiding the scar. I didn't want my son to think my scar was something to be ashamed of. I'm his role model and I needed to set a good example. Bad things can happen, but it's how you deal with them that matters.The scar proves I faced my fear and won. If I got through that, I can get through all the hardships, land on my feet and live boldly.4. How did the author feel about the would－be scar across her neck at first?A. Comfortable and relieved.B. Anxious and frightened.C. Indifferent and unconcerned.D. Thrilled and embarrassed.5. What do the underlined words “wimp out” in Para graph 3 refer to?A. Challenge oneself.B. Ignore pain.C. Overcome fear.D. Lose courage.6. Why did the author want to get her hair styled?A. To show her scar bravely.B. To shape beautiful hair.C. To hide the obvious scar.D. To make her son proud.7. What is the story intended to convey?A. We should never hide our scars or any other pain.B. Scars can never be regarded as personal signature.C. We should challenge difficulty and face fear bravely.D. Parents should set a good example for their children.CYoung sunflowers turn and swing every day. New findings add to evidence thatthe plants are animal-like. Harmer, a professor in the University of California at Davis’ Department of Plant Biology, carried out a serie s of experiments on sunflowers in the field, in pots outdoors and in indoor growth chambers.By staking plants so that they could not move, Harmer showed that he could destroy their ability to track the sun. He also noticed that sunflowers prevented from moving were not as tough and leafy as those that were free to move. When plants were moved indoor with a settled overhead light, they continued to swing back and forth for a few days.The indoor plants did start tracking the “sun” again when the apparent so urce of lighting was moved across the room. The plants could reliably track the movement and return at night when the artificial day was close to a 24-hour cycle, but not when it was closer to 30 hours.When sunflowers track the sun, the east sides of their stems grew more rapidly than the west sides. At night, the west sides grew faster as the stem swung the other way. The team identified a number of genes that were expressed at higher levels on the sunward side of the plant during the day, or on the other side at night. A plant growth-regulating hormone, called auxin, appears to be a key driver.The “dance” to the sun cycle obviously slows when the sunflower matures and its flowers open up. At that point, the plants stop moving during the day and settle down facing the sun in the east.“Bees like warm flowers.” Harmer said, adding that the bees are cold-blooded, so landing on a warm flower saves them energy and perhaps feels really good.“The morning warmth changes the flowers in a way to make them more app ealing to insects, perhaps causing them to release more attractive scents earlier in the day.” he said. “We’re currently testing this idea.”8. Why did Harmer do the experiment on sunflowers?A. To see how sunflowers grow up.B. To show what sunflowers’ genes are.C. To study why sunflowers track the sun.D. To check if sunflowers swing in cloudy days.9. What does the underlined word “staking”(Par 2) probably mean in ?A. Tracking.B. Fastening.C. Preserving.D. Presenting.10. What is the result of sunflowers being stopped from moving?A. They won’t grow well.B. They will grow faster than usual.C. They won’t swing back though set free.D. They will produce a number of new genes.11. Bees are fond of dancing ______________.A. on cold sunflowersB. in the circle of flowersC. on warm sunflowersD. on the mature sunflowersDUnited States health officials are urging people to stop using electronic cigarettes, known as e-cigarettes. The call to action came after such products were linked to health problems. Five deaths have also been reported. E-cigarettes are a popular substitute for smoking products. The electronic devices heat liquid thatincludes flavoring, nicotine and other chemicals into vapor-very small particles that users breathe in. Nicotine is found in many plants, including tobacco. E-cigarettes or similar devices also can provide THC or other substances to users. THC is the natural chemical present in marijuana(大麻) plants that gives users the mental state known as a “high”．E-cigarettes are said to be safer than normal cigarettes because they do not create the cancer－causing byproducts of burning tobacco.Yet health officials say e-cigarette users have reported shortness of breath and other breathing problems, such as coughing and chest pain. Some have been sick to the stomach, felt very tired, suffered weight loss or developed high body temperatures. One report noted that most of the 53 illnesses reported in Illinois and Wisconsin were related to THC vaping(气化) products. But nearly 20 percent of the patients inhaled(吸入)substances like nicotine from e-cigarettes.
