New figures show that one in five households no longer bother with a landline（固定电话），and almost a third of those that do never actually use it.The vast majority of people who still have a home phone ——72 percent ——say they only have it because it is part of their broadband package.But that's not the only reason to desert the home phone - 20 percent of those surveyed said that they were fed up with the number of cold calls and would-be scammers（诈骗者）.Digital media expert Dr. Elinor Carmi said there was a generational and social divide in phone use. She explained："If you,re young and have the mobility to go outside, you would rely on a mobile phone. But if you are older, disabled and perhaps poorer, our research shows you're more likely to use a landline. If you are richer, you will have access to more smart devices --- a smart TV, smartphone or laptop. But the poorer you are --- or if you are older, your use of these devices is more limited.”Last year, research from regulator Ofcom found that the amount of time spent on landline calls annually in theUKhad halved over just six years, to 54 billion minutes. The new study also showed that more than a quarter of households have decided to find a broadband provider that does not charge for their unused landline, but only six percent have done so.4. The underlined part “ a white elephant" in Paragraph 1 probably refers to something that isA. costly but effectiveB. useful and beautifulC. expensive but uselessD. cheap and necessary5. What's the main reason why some people still have a home phone?A. Their broadband package contains it.B. Their family can only afford to use it.C. They are used to using a home phone.D. They consider it an important status symbol.6. Which of the following is more likely to use a landline?A. A young adventurer.B. An old poor gardener.C. An outdoor photographer.D. A famous indoor designer.7. What's the best title of the text?A. End of the landline?B. Fed up with cold calls?C. The history of phonesD. Different choices of phonesCDogs are often called as “man's best friend”, MacKenzie, a four-pound Chihuahua（吉娃娃）, was named winner of the 2020 American Hero Dog Competition on October 19, 2020.In its tenth year in 2020 the annual contest is the brainchild of American Humane, the country's first national charitable organization founded for the safety and well-being of animals. Often called the “Oscars for dogs”, the award recognizes dogs who make extremely great contributions to society.The competition of 2020 attracted over 400 entries（参赛者）from across the country. These heroic dogs have gone above the call of duty, saving lives, comforting the ill and aged and reminding us of the powerful, age-old ties between animals and people. While all were impressive, it was tiny MacKenzie who wonthe judges' hearts.MacKenzie's growth was not easy. Born with a mouth disability, she had to be fed through a tube（管子）for the first year of her life. Despite her own struggles, she always seemed to think more of other animals in need. “Never have I seen such a will to live. Though sick, she carefully looked after the baby animals at the rescue（救助）center,” said her caretaker.A life-saving operation performed in 2014 gave MacKenzie the ability to eat independently. The seven-year-old chihuahua is now working for the Mia Foundation, an organization that rescues and nurses animals with inborn disabilities. The chihuahua does an excellent job and has raised various animals. She plays nurse, cleans, comforts and hugs them, acting as their mother and teaching them how to socialize, play and have good manners.In addition to her role as an animal caretaker, MacKenzie also visits schools to educate kids about the importance of accepting physical differences in both animals and people. Her heartwarming and inspiring story makes MacKenzie a worthy receiver ofAmerica's top dog honor.8. What can we infer about the American Hero Dog Competition?A. It was first held in 2010B. It was held to honor caretakers of dogs.C. It takes place every ten years.D. It was started by a charitable organization.9. With what quality did MacKenzie win the award?A. Talent and braveryB.

Understanding the disabled.C. Valuing physical health.D. Developing practical ability.11. What's the best title for the text?A. Dogs Are Man's Best Friends.B. Treat Dogs the Way We Want to Be Treated.C. Touching Stories between MacKenzie and PeopleD. 2020 American Hero Dog: A TinyChihuahua.DANew Zealandcouncil has announced a month-long road closure in order to allow a sea lion and her pup to reach the ocean safely.John Wilson Ocean Drive in Dunedin will be closed after the New Zealand sea lions made their home at a nearby golf course and started "regularly crossing the road to get to the beach," according to a Facebook post from Dunedin City Council."You can still visit the area on foot or by bicycle, but please give the sea lions lots of space," continued the post.Locals applauded the decision, and one even called for the closure to be made permanent."No dogs should be on the beach, either," wrote Gaylene Smith.

However, the picture for hydropower is more complicated than we think.A new study by the Environmental Defense Fund analyzed the climate impacts of 1,500 hydropower facilities across the globe. That accounts for about half of hydropower generation worldwide. The researchers looked at whether the facilities behave as a greenhouse gas sink or as a source. To figure this out, they looked into all the different components that help determine a hydropower facility's greenhouse gasemissions (排放).“There are so many contributors to greenhouse gas emissions from hydropower — but essentially, the majority of greenhouse gas emissions arise from the reservoir (水库) itself, as vegetation and soils are submerged underwater in the dam thatis used for the hydropower generation.” said lissa Ocko, a senior climate scientist at the Environmental Defense Fund and co-author of the study. As the submerged vegetation breaks down, it releases greenhouse gases such as CO2.“The larger the surface area of the reservoir, the more greenhouse gases are going to be given out from that reservoir. Also, the temperature plays a role as well how warm the reservoir is will affect how much greenhouse gases are produced and given out from the reservoir.” added Ocko.Through their analysis, Ocko and her co-author Steven Hamburg, also with the Environmental Defense Fund, discovered that the climate impacts of hydropower cover a complete range. The good news is that some facilities perform just as well as wind and solar. But shockingly, more than 100 facilities are actually worse for the climate than fossil fuels. The study is in the journalEnvironmentalScience and Technology.This finding doesn't mean we should forget about hydropower. “But we just need to be careful to make sure that we have climate benefits. There are a lot of situations where hydropower can be equal to wind and solar. So it really depends on the specific facility." said Ocko.4. How do scientists prove hydropower facilities' effect on the climate?A. By making comparisons.B. By conducting experiments.C. By referring to previous studies.D. By analyzing causes and effects.5. What are the main sources of greenhouse gases from hydropower?A. Vegetation and soils.B. Heat and sunlight.C. Pollutants in the reservoir.D. Components of the generators.6. What have Ocko and her co-author Steven Hamburg found?A The surface area of a reservoir decides the climate.B. Hydropower often influences the climate in all aspects.C. Some facilities perform much better than wind and solar.D. Fossil fuels are worse for the climate than over 100 facilities.7. What is the text mainly about?A. Scientists urge an end to hydropower.B. Hydropower is not necessarily green.C. Hydropower is worse than fossil fuels.D. Renewable energy is a complicated issue.CImagine that youare a superhero. Your superpowers are activated by a special suit. The suit communicates with your brain. It allows you to do amazing things with only a thought. By concentrating on strength, for example, you can kick a soccer ball across a field. By focusing on swift actions, you can jump to the top of a tree.Such a connection between mind and machine may sound like a fantasy. To scientists, though, it is a very real goal. They are creating machines that let disabled monkeys walk. These machines may soon help disabled humans do the same. Unlike other bionic devices, these robotic “super suits” do not communicate with muscles and nerves. Instead, they have a direct line to the brain.In 2005, doctors drilled a hole in the skull of Hutchinson, who had lost her right arm in an accident. Then they inserted a sensor onto her motor cortex (大脑皮层运动区). Wires connected the sensor to a receiver on her head. After she recovered, researchers pluggedHutchinson’s receiver into a cable that relayed signals from her brain to computers. Then they connected a robotic arm to the computers. The computerscould interpretHutchinson’s brain signals to move the arm.Soon,Hutchinson, the computer, and the robotic arm became a team.Hutchinsonwas even able to lift her hand and drink from a cup. “She smiled when she put down that drink—that’s everything.” says Donoghue, a brain scientist.Today other scientists are building on that success. One of those scientists is Dr. Miguel Nicolelis, who designed a whole-body bionic equipment. In 2014, a disabled former athlete kicked the first ball of the World Cup Games wearing one of Miguel’s full-body exoskeletons.The exoskeleton was connected to brain signal sensors in the man’s cap. By thinking about kicking, he sent signals to a computer on his back. The computer then translated the signal into an exoskeleton-aided kick. Such designs may become common as scientists keep merging mind and machine.8.Which can best describe the tone of paragraph 1?A. Narrative and serious.B. Persuasive and critical.C. Informative and objective.D. Descriptive and imaginative.9. What is paragraph 3 mainly about?A. Reason of the experiment.B. Results of the experiment.C. Process of the experiment.D. Significance of the experiment.10. Why is Dr. Miguel’s exoskeleton special?A. It can be used on animals.B. It can move the whole body.C. It was supported by computers.D. It was connected directly to the brain.11. What can be inferred from the last paragraph?A. Robotic suits may be widely used to help disabled people.B. Exoskeleton is more common thanHutchinson’s bionic arm.C.Scientific experiments are commonly carried out in football fields.D. Disabled athletes can now play football again with the help of computer.DJennifer Mauer has needed more willpower than the typical college student to pursue her goal of earning a nursing degree. That willpower bore fruit when Jennifer graduated from University of Wisconsin-Eau Claire and became the first in her large family to earn a bachelor's(学士) degree.Jennifer grew up on a farm in a family of 10 children. Her dad worked at a job away from the farm, and her mother ran the farm with the kids. After high school, Jennifer attended a local technical college, working to pay her tuition(学费), because there was no extra money set aside for a college education. After graduation, she worked to help her sisters and brothers pay for their schooling.Jennifer now is married and has three children of her own. She decided to go back to college to advance her career and to be able to better support her family while doing something she loves: nursing. She chose the UW-Eau Claire program at Ministry Saint Joseph's Hospital in Marshfield because she was able to pursue her four-year degree close to home. She could drive to class and be home in the evening to help with her kids. Jennifer received great support from her family as she worked to earn her degree: Her husband worked two jobs to cover the bills, and her 68-year-old mother helped take care of the children at times.Through it all, she remained in good academic standing and graduated with honors. Jennifer sacrificed(牺牲) a lot to achieve her goal, giving up many nights with her kids and missing important events to study. “Some nights my heart was breaking to have to pick between my kids and studying for exams or papers,” she says. However, her children have learned animportant lesson, witnessing their mother earn her degree. Jennifer is a first-generation graduate and an inspiration to her family—and that's pretty powerful.12. What did Jennifer do after high school?A. She helped her dad with his work.B. She ran the family farm on her own.C. She taught her sisters and brothers.D. She supported herself through college.13. Why did she choose the program at Ministry Saint Joseph's Hospital?A. To learn from the best nurses.B. To take care of her kids easily at night.C. To save money for her parents.D. To find a well-paid job there.14. What did Jennifer sacrifice to achieve her goal?A. Her health.B. Her chance of promotion.C Her reputation. D. Her time with family.15. What can we learn from Jennifer's story?A. Hard work pays off.B. Love breaks down barriers.C. Time is money.D. Education is the key to success.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。

Last September the couple moved into a 1,500-square-foot home in Premier Gardens, an area of 95 “zero-energy homes” (ZEH) just outside town. Now they're actually eager to see their electricity bills. The grand total over the 10 months they've lived in the three-bedroom house: $75. For the past two months, they haven’t paid a cent.ZEH communities are the leading edge of technologies that might someday create houses that produce as much energy as they consume. Premier Gardens is one of a half-dozen subdivisions (住宅开发项目) in California where every home cuts power consumption by 50%, mostly by using low power appliances and solar panels.Aside from the panels on the roof, Premier Gardens looks like a community of traditional homes. But inside, special windows cut power bills by blocking solar heat in summer and keeping indoor warmth winter.The rest of the energy savings comes from the solar units. They don't just feed the home they serve. If they generate more power than the home is using, the excess flows into the utility's power grid(电网). The residents are billed by “net metering”: they pay for the amount of power that they get from the grid, minus the kilowatts(千瓦) they feed into it. If a home generates more power than it uses, the bill is zero.That sounds like a bad deal for the power company, but it's not. Solar homes produce the most power on the hot sunny afternoons when everyone rushes home to turn up the air conditioner. "It helps us lower usage at peak power times," says solar expert Mike Keesee. “That lets us avoid building costly plants or buying expensive power at peak usage time.”What’s not to like? Mostly the costs. The special features can add $25,000 or more to the purchase price of a house. Tax breaks bring the cost down, especially in California, but in many states ZEHs can be extremely expensive. For the consumer, it's a matter of paying now for the hardware to save later on the power bill.4. Why is the Gata eager to see their electricity bills now?A. They want to cut down their utility' expenses.B. They want to know if they are able to pay.C. They want to see how much they have saved.D. They want to avoid being overcharged.5. What is special about the ZEH communities?A. They are built in harmony with the environment.B. They have created cutting edge technologies.C. They are subdivided into half a dozen sections.D. They aim to be independent in power supply.6. What does the "net metering" practice mean to the power company?A. More pressure at peak timeB. Reduced operational costs.C. Increased electricity output.D. Less profits in the short term.7. The author believes that buying a house in a ZEH community __________.A. is a worthy investment in the long runB. is but a dream for average consumersC. gives the owner great tax benefitsD. contributes toenvironmental protectionCWhen you say the word donkey, whatthings come to your mind? A few people might say they’re cute, but the majority think they’re stubborn, dumb and all-round less capable than their horse s.However, this wasn’t the case for a recently unearthed ancient Chinese noblewoman who was unexpectedly found buried with her donkeys. Published in the journal Antiquity in March, Chinese archaeologists (考古学家) first discovered the tomb in Xi’an, Shaanxi, in 2012. The team examined the remains and identified the body as Cui Shi, a Tang Dynasty high-born lady who died in 878 AD.Speaking to Science Magazine in 2012, the study’s co-author, Fiona Marshall, said the finding caused confusion as “donkeys … are not associated with high-status people”.However, following years of further research, the team discovered artworks and artifacts that showed a sport known as “Lvju”. This was similar to modern-day polo (马球)and was popular among noble (高贵的) women at the time. They preferred to use donkeys instead of full-sized horses for safety reasons, due to their smaller size and slower speed.Speaking to CNN, Marshall later said, “Historical documents also showed that ladies of the late Tang court loved to play donkey polo.”At that time in Chinese history, animals were often placed in tombs so that they could be used for a specific purpose in the afterlife. The study determined that Cui Shi likely requested that her beloved donkeys be buried with her, so that she could continue her favorite sport after death. In total, three donkeys were found inside her tomb with riding gear (装备), including stirrups (马镫). “This context provides evidence that the donkeys in her tomb were for polo, not transport,” lead author Hu Songmei of the Shaanxi Academy of Archaeology told Science Magazine.Before the study, it was believed that donkeys were only used to carry loads, but now it may be time to seethem as a sign of achieving high social status(地位), well, in ancient times.8. What do most people think of donkeys, according to the text?A. They are as adorable(可爱的) as horses.B. They are stubborn and not so capable.C. They were necessary in ancient sports.D. They were a sign of high social status.9. Why did Fiona Marshall feel confused when she discovered the donkeys?A. She didn’t connect donkeys with nobles.B. She hadn’t seen donkeys in ancient tombs before.C. She didn’t expect to find donkeys in a woman’s tomb.D. She didn’t understand why animals were in human tombs.10. What do we know about the sport “Lvju” from the text?A. Horses were preferred in Lvju.B Lvju was similar to modern-day soccer.C. Lvju was popular among common people.D. Donkeys were preferred in the sport for safety.11. The donkeys were found in the tomb of Cui Shi probably because _______.A. she intended to use them for transport after deathB. her family didn’t want her to be lonely after deathC. she wanted to continue to play Lvju after deathD. noble women needed donkeys to maintain their dignityDWhen you walk with a backpack, do you know how the things inside move from side to side? Now scientists havefigured out how to tap into that movement to produce electricity.Picture a pendulum (摆锤) fixed to a backpack frame and stabilized with springs on either side. The pack’s weight is attached to the pendulum, so the pendulum swings side to side as you walk.Then a machine is driven by that swinging movement, and spits out electrical current to charge a battery.Volunteers carried the pack while walking on a running machine and wore masks to measure the flow of O2and CO2. Walking with the slightly swinging 20-pound load, the device (设备) did not significantly affect the volunteers’ metabolic (新陈代谢的) rate compared to when they carried the same weight fixed in place. In fact, the energy-harvesting pack reduced the forces of acceleration they’d feel in a regular pack, which might mean greater comfort for a long hike. And the device did produce a steady trickle (涓流) of electricity. If you up the loadto 45 pounds, the swing of the pack could fully charge a smart phone only after 12 hours. The details are in the journal Royal Society Open Science.The device produces electricity from human movement and has been identified as a workable solution to providing a renewable energy source for portable electronic devices. It is particularly useful for those who work in remote areas, as these people often carry a lot of weight in a backpack for their exploration.But here’s a realconundrum: the energy-harvesting device currently weighs five pounds. The researchers say that’s about four pounds too many to be a smart alternative to batteries. So they hope that more research lets them lighten the load, to ensure the pack charges you up without weighing you down.12. What does Paragraph 2 mainly talk about?A. How the device works.B. What the device looks like.C. Who the device is designed for.D. Why scientists designed the device.13. Which of the following describes the device?A. It greatly affected the volunteers metabolic rate.B. It harvested energy as the volunteers walk.C. It failed to produce steady electricity.D. It was useless for a long walk.14. What does the underlined word “conundrum” in the last paragraph mean?A. Problem.B. Method.C. Bond.D. Decision.15. What will the researchers try to do next?A. Increase the charging speed of their device.B. Find smarter alternatives to batteries.C. Reduce the weight of their device.D. Put their device on the market.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。

Taylor, Amber and their girls Finley, 6,and Sadie, 4, soon woke up and came downstairs, too. “Well, it was dark so we couldn't see anything, only could hear Marley,” Amber recalled, saying her husband then went for the lights. “And once he turned the hall light on, we realized that the guy was holed up in the corner trying to hide.”“So I think he got to the front door and realized he couldn't get out, and by that point in time, Marley's got him cornered,”Taylorsaid. Pham slashed (砍) both Marley and Taylor, and blood went everywhere. Taylor shared a video summary to his Facebook page, where he said Marley was stabbed (刺) up to six times, mostly around the head and neck area. “And as I pulled back, blood shot out of my arm,”Taylorcontinued. “She got him pretty good and I got him pretty good in the face.”“But it was really hard because I was trying to make sure that my husband wasn't going to die,” Amber explained, adding that she was trying to protect their two girls. “When he realized that the two girls were in the house, that's when he kind of backed up and started running. "Taylorexpressed gratitude to everyone for their thoughts and prayers. And the family is thankful for their dog Marley.“She's our hero,” Amber said. “If it hadn't been for her, that guy could have gone in the...he could have gone to their rooms or something.”Tayloradded, “Yeah, I mean, the story plays out very differently if Marley's not there.”1.

Clothing renting is a hot new industry and businessmen are trying to attract shoppers who care about the environment. Last summer alone,Urban Outfitters, Macy’s, Bloomingdale’s American EagleandBanana Republicall announced renting services – a sure sign of changing times.But is renting fashion actually more environmentally-friendly than buying it? And if so, how much more? Journalist and author Elizabeth Cline researched this question in a feature article for Elle, and she concluded that it’s not as sustainable as it seems.Take shipping for example, which has to go two ways if an item is rented – receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint of our collective fashion habit after manufacturing.Then there’s the burden of washing, which has to happen for every item when it’s returned, regardless of whether or not it was worn. For most renting services, this usually means dry-cleaning, which is a polluting process. All the renting services that Cline looked into have replaced perchloroethylene, a carcinogenic (致癌的) air pollutants that’s still used by 70 percent of US dry cleaners, with hydrocarbon (碳氢化合物) alternatives, although these aren’t great either. They can produce harmful waste and air pollution if not handled correctly.Lastly, Cline fears that renting services will increase our appetite for fast fashion, simply because it’s so easily accessible. There’s something called “share-washing” that makes people have more wasteful behaviors because a product or service is shared and thus is considered more eco-friendly. Uber is one example of this: advertised as a way to share rides and reduce car ownership, and yet it has been proven to discourage walking, bicycling and public transportation use.Renting clothes is still preferable to buying them cheap and throwing them into the bin after wearing them a few times, but we shouldn’t let the availability of these services make us self-satisfied. There’s an even better step – and that’s wearing what we already have.4. What do we know about Elizabeth Cline from the passage?A. She is trying to attract shoppers.B. She is an expert and journalist.C. She has created “share-washing”.D. She never rents clothes.5. Why does renting services increase people’s appetite for fast fashion?A. Because it is handled correctly.B. Because it is transported easily.C. Because it is fairly eco-friendly.D. Because it is easily accessible.6. What can we infer from the passage?A. Clothing renting became popular ten years ago.B. Consumer transportation has the largest carbon footprint.C. Renting clothes deserves further consideration.D. Uber is a good example of sharing rides.7. Which section of a newspaper does the text probably come from?A. Environment.B. Technology.C. Travel.D. Medicine.CMany of us were delighted to learn that a high school senior Kwasi Enin was accepted to all eight Ivy League universities. To our surprise, he wasn't excited as expected, but appeared extra calm. He announced that he would revisit the universities to find the best suitable in music or medicine. He also wanted to compare their financial aid packages.Kwasi's success story is rare, but his reaction is not. After the admission letters arrive at home, students have 30 days to really think about what kind of school would help them grow as a person, which school would best prepare them for the future, and at which school they would be happiest. And they also have to think about whether they can afford the school they choose.But how to answer the questions about which school is the best suitable university? Some young people are attracted to large universities with great school spirit and a list of offerings. But besides those advantages, many of these universities focus on graduate work and research, with undergraduates taught mostly by part-time instructors. Others are attracted to smaller boarding schools with discussion-based classes. But some of these schools will have much limitation for students who want a high-energy city life experience.Many students today seem to think they should pick the university where they will get the diploma that will help them get the most highly paid job. This is a sad misunderstanding of what a college education should provide.A good college education should prepare them to overcome any difficulty andthrivein society. It helps them to form the habit of creative mind and spirit that will continue to develop far beyond their university years. So whenyou choose college, you should consider if it is filled with useful learning to help create new spaces for different possibilities of growth.8. What can we know about Kwasi Enin from paragraph 1?A. He was from a very poor family.B. He would choose the top university.C. He was too excited to calm himself at the good news.D. He considered his interests when choosing his university.9. What can you infer from paragraph 2?A. Few students can be admitted to university.B. Many students face the choices like Kwasi.C. Top universities are the first choice for most students.D. American students can afford their university by themselves.10. Which of the following can best explain the underlined word “thrive” in paragraph 4?A. FailB. SucceedC. ResearchD. Work11. What should the best university be like according to the text?A. Very large and have good instructors.B. Small boarding schools with discussion-based classes.C. It will offerthe diploma to get the most highly paid job.D. It will help continue to develop far beyond university years.DWe all know that a healthy lifemeans getting both plenty of exercise and enough good-quality sleep, but reality often gets in the way. The new research indicates that doing enough exercise could make up for some of the unhealthy impacts of bad sleep. While the health benefits of exercise and sleep are nothing new, it's the relationship between them that is interesting in this particular study — it could even give doctors another option to suggest for patients dealing with sleep problems.“We found those who had both the poorest sleep quality and who exercised the least were most at risk of death from heart disease, stroke, and cancer,” says epidemiologist Bo-Huei Huang, from the University of Sydney in Australia.Participants were grouped into three levels of physical activity (high, medium or low) and were also given a sleep quality score from 0-5 based on the amount of shut-eye they got, how late they stayed up, insomnia, snoringand daytime sleepiness.Those with the highest risk of dying from cancer or heart disease during the study period were those with the worst quality sleep and who didn't meet the WHO recommended guidelines for exercise. That risk went down for people with poor quality sleep but who did meet the exercise guidelines.In the case of all forms of cancer, for example, those at the unhealthiest end of the sleep and exercise scale had a 45 percent higher risk of dying from cancer than those with good sleep scores who kept physically active. However, that risk just about disappeared for those who didn't score well on sleep but did score well on physical activity.For now it's not clear why more exercise might make up for poor sleep, as far as our health goes. It could be that the increased activity iscounteractinginflammation (炎症), or reducing irregularities in glucose metabolism, suggest the researchers.“Considering that physical activity is perhaps more modifiable than sleep, our study offers people more health incentives to be physically active.” says population health researcher Emmanuel Stamatakis, from the University of Sydney.12. This research is of particular interest in that ________.A. it’s in this study that exercise is known to be beneficial to sleep.B. this study offers people more health treatments to be physical active.C. it could enable doctors to cure patients of their sleeping condition.D. the relationship between exercise and sleep is updated in this study.13. Which of the following statements istrueaccording to the passage?A. Those who had the poorest sleep quality were most at risk of death from heart disease.B. Those scoring lowest on sleep and exercise scale were more likely to die from cancer.C. There’s no risk of cancer for those who didn't sleep well but did score well on physical activity.D. It's evident that in terms of health more exercise could make up for poor sleep.14. What does the underlined word in Paragraph 6 mean?A. interactingB. increasingC. preventingD. causing15. Where can this passage most probably be taken from?A. A research findings reportB. A medical examination reportC. A poor sleep study reportD. A physical activity study report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。

They found that the most environmentally friendly and cost-effective approach would be for more food producers to adopt the nitrogen-efficient “intensive” farming method, which involves the heavy use of labor and the production of more crops per acre.This approach was shown to be more effective than the “extensive” farming currently practiced by many poor nations, a method that includes clearing more new land to produce more food.Different farming methods produce significantly different yields, the researchers found — in 2005, the crop yields for the wealthiest nations were more than 300 percent higher than what the poorest nations produced.According to their analysis of the effects of extensive farming, if poorer nations continue using this method, by 2050theywill have cleared an area larger than theUnited States, about 2.5 billion acres. However, if wealthy nations help poorer nations to improve food yields by incorporating(吸收) intensive farming practices, thatnumber could be reduced to half a billion acres.The researchers stress that the environmental effects of meeting future food demand depend on how global agriculture expands and develops.“Our analyses show that we cansave most of the Earth’s remaining ecosystems by helping the poorer nations of the world feed themselves,” Tilman said.4. What is the best title of this passage?A. The World Will Need Double Food by 2050B. Man Will Face the Risk of Lacking Food in the FutureC. Future Farmers Hold Environment’s Fate in Their HandsD. Different Farming Methods Produce Significantly Different Yields5. The character of the extensive farming is ________.A. very cost-effectiveB. to produce more crops per acreC. at cost of more new land to produce more foodD. very environmentally friendly6. It can be inferred from the passage that ________.A. poorer nations mainly use the intensive farmingB. wealthy nations mainly use the extensive farmingC. the intensive farming needs less food producersD. the extensive farming has a worse effect on ecosystems7. According to the passage, the underlined word “they” in the 7th paragraph refers to “________”.A. poorer nationsB. the effects of extensive farmingC. wealthy nationsD.future food demandCWhat acts of kindness will make us the happiest, and who tends to benefit the most? A newly-published review of decades of kindness research provides some answers.In this paper, researchers analyzed the results from 126 research articles looking at almost 200, 000 participants from around the world. The studies they chose measured well-being in various ways, including bothmental and physical health. Some were experiments, where people did a kindness practice to observe its effects, while others just surveyed people about how kind and happy they were.As expected, people who were kind tended to have higher well-being. Lead researcher Bryant Hui wasastoundedthat the relationship wasn't stronger than it was, but he was still encouraged by the results.One thing Hui and his colleagues found was that people who performed random, informal acts of kindness, like bringing a meal to a sad friend, tended to be happier than people who performed more formal acts of kindness, like volunteering in a soup kitchen.The researchers also found that people who were kind tended to be higher in "eudaimonic happiness"(a sense of meaning and purpose in life) more than "hedonic happiness"(a sense of pleasure and comfort). Perhaps this makes sense, given that being kind takes effort, which reduces comfort but could make people feel better about themselves and their abilities, which would provide a sense of meaning.Being kind came with greater eudaimonic happiness for women than for men, too. According to Hui, this could be because, in many cultures, women are expected to be kinder than men; so, they may have more to gain from it. And younger participants experienced more happiness when they were kind than older participants, perhaps for developmental reasons, he says.Hui isn't sure why acting kind might have these different effects on different groups, but he points to theories put forth by researcher Elizabeth Midlarsky: Being kind may make us feel better about ourselves as a person or about the meaning of our lives, help us forget our own troubles and stresses, or help us be more socially-connected with others.8. What does the data in the second paragraph intend to show?A. The recent paper is worthy of being read.B. The recent paper gives convincing results.C. Kindness is always a hot topic of research.D. Kindness is closely linked to one's well-being.9. What does the underlined word "astounded" in paragraph 3 mean?A. Afraid.B. Certain.C. Excited.D. Surprised.10. Which of the following acts of kindness can make one feel happier according to paragraph 4?A. Volunteering in a hospital.B. Cleaning a community.C. Returning a lost item to its owner.D. Collecting donations for the poor.11. What do the researchers find from the paper?A. Being kind has different effects on different groups.B. Eudaimonic happiness makes people feel comfort.C. The younger experienced more happiness than the older.D. Female participants are kinder than male ones.DMy first week working in a restaurant, one of the servers said something that stuck with me: Everyone should work in a restaurant for at least a year. At the time, I didn't get it, but I took the advice to heart and worked in restaurants on and off for the next eight years. Before realizing it, I mastered many important skills, one of which is communication skill.When I was little, I was so shy that I used to hide behind my mom whenever someone spoke to me. And when I first started in restaurants, I had two personalities: Restaurant Lizzy and Home Lizzy. It was easier to pretend to be a different person while at work, since it was so different from who I actually was. But gradually, the skills I learned working in restaurants helped Home Lizzy come out of her shell in the real world.When you work in a restaurant, you don't have the luxury of hiding behind your parents to avoid talking to people. I'm still 110% an introvert, but restaurant work helped me communicate. Working in a restaurant not only helped me speak clearly, deliberately and directly but also taught me how to talk about almost everything. Some guests don't want their servers to interact too much with them, and that's fine. But some sit at the bar simply to chat with you. You learn how to judge your guests' level of interest in communicating with you, and how to exit a conversation at the appropriate time.My restaurant work is something that I'm most proud of and I know I wouldn't be the person I am today without those eight years of experience. If you're still on the fence about working in a restaurant for that long, start with one year. I doubt that you'll look back.12. What did the writer think of the server's words?A. Impressive.B. Ridiculous.C. Amusing.D. Logical.13. What do we infer from Paragraph 2?A. The writer tried different jobs.B. The writer became more sociable.C. The writer used an invented name.D. The writer had a hard time at work.14. Which of the following best describes the writer's restaurant work?A. Boring.B. Relaxing.C. Worthwhile.D. Unchallenging.15. What message does the writer try to convey in this passage?A. A strong-willed soul can reach his goal.B. Things are difficult before they are easy.C. Communication skills advance your career.D. Restaurantwork helps to achieve a better self.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。

Under the surface, the earthquake caused strong currents that swept away and mostly killed off diverse ecosystems of creatures living along the Kaikoura underwater canyon.As a result, whales had to dive deeper and longer to find food—“a major shift” in their behavior, says co-author Liz Slooten, a marine biologist at the University of Otago in New Zealand.The impact earthquakes have on land animals has been well documented, but scientists know ly little about what happens underwater. Such research is important for government agencies, which may need to take recent earthquakes into consideration when considering fishing quotas（限额）, notes Rochelle Constantine, a marine mammal ecologist at the University of Auckland.The canyon’s upper reaches are rich in creatures, supplying food for the fish that make up the whales’ diet. So when these smaller life forms were washed away, it had “severe consequences for the community around there”, says study co-author Will Rayment. “That effect flowed all the way through the food chain.”As part of their ongoing study, the scientists were tracking 42 individual whales. After the earthquake, in all, the team managed to record data on 40 whales, showing that the abundance of whales in the general area didn’t change after the earthquake. However, the whales changed how they used their habitat.A year after the earthquake, the researchers observed the whales returning to their previous surface-breathing intervals. This could have been because the communities of animals that make up the whales’ food began to recover. “It gives you an idea of how resilient（有复原力的）these deep-sea communities are,” says Rayment.But he and his colleagues will continue long-term monitoring to see if there are effects they missed. Whale activity in the area had already been declining, though it’s unknown whether it is due to natural changes in food abundance, whale-watching tourism, fishing, or warming ocean temperatures. “There is something going on in Kaikoura,” says Rayment.4. What happened after the Kaikoura earthquake in the Kaikoura canyon?A. Several destructive tsunamis struck the area.B. Whales had to swim to other oceans to find food.C. Nearly all marine creatures in Kaikoura were killed off.D. Strong currents washed away many smaller creatures.5. Which is one of the findings of the study?A. Earthquakes can make it easier for whales to find food.B. The whales changed their habitat after the earthquake.C. It usually takes whales a year to adapt to their new diet.D. The number of whales in the area dropped sharply after the quake.6. What does Rochelle Constantine think of the study?A. It can help government agencies to make some decisions about fishing.B. It can help government agencies to solve problems in the fishing industry.C. It is a breakthrough in research on what happens underwater after an earthquake.D. It offers a detailed description of the impact earthquake have on marine mammals.7. What can we infer from the last paragraph?A. Something is affecting the whale activity in Kaikoura.B. Fishing quotas have been increasing in recent years.C. The team missed some effects in the research process.D. The scientists will continue studying earthquakes.CIn a world simultaneously on fire and underwater thanks to climate change, scientists have announced some good news: Several important tuna (金枪鱼) species have stepped back from the edge of extinction.The unexpectedly fast recovery speaks to the success of efforts over the past decade to end overfishing. But tuna are not the only species scientists are discussing at the 2021 World Conservation Congress in Marseille, France, which is organized by the International Union for Conservation of Nature (IUCN). Researchers caution that manyother marine species remainimperiled. For instance, more than a third of the world's sharks remain threatened with extinction due to overfishing, habitat loss, and climate change.“I think the good news is that sustainable fisheries are possible,” says Beth Polidoro, a marine biologist at Arizona State University. “We can eat fish in a proper way and without driving the population to the point where it is on the road to collapse or extinction."At the same time, she warned that the changes in status should not be an reason to catch as many fish as we want.The IUCN, which ranks the world's most endangered species on its Red List of Threatened Species and is backed by 16,000 experts across the globe, also announced at the meeting that some animals are moving in the other direction, onto the Red List. One notable example is the Komodo dragon, an island-living lizard at particular risk from climate change.For the better part of two decades, Polidoro has been part of a specialist group tasked with assessing the statuses of more than 60 species of tuna and billfishes for the IUCN.Her team announced its first comprehensive findings in 2011, mentioning that a number of commercially fished tuna species were dangerously close to disappearing.According to the new data, the Atlantic bluefin tuna (Thunnus thynnus), once listed as endangered, now qualifies for a status of least concern. As does the yellowfin tuna (Thunnus albacares) and albacore tuna (Thunnus alalunga), which were both considered near-threatened the last time they were assessed.8. What does the underlined word “imperiled” in paragraph 2 mean?A. EndangeredB. ConservedC. ExtinctD. Safe9. What can we infer from Polidoro's words?A. Too many fish are being eaten by human beings.B. Eating fish does not necessarily lead to its extinction.C. Fish species are on the edge of dying out if no action is taken.D. The situation of underwater species are changing for the better.10. Which of following statement is true according to the passage?A. Some Tuna species are wiped out by overfishing.B. Tuna are ranked as the world's most endangered species.C. Climate change poses a threat to most species in water and on land.D. Three tuna species have been saved from extinction according to the data.11. What's the main idea of the passage?A. Some tuna species are reported endangered recently.B. IUCN has helped saved a great many marine species.C. Improvement has been made in saving marine species.D. Great efforts should be made to conserve species underwater.DA growing body of research is revealing associations between birth defects (缺陷) and a father's age, alcohol use and environmental factors, say researchers atGeorgetown University Medical Center. They say these defects result from epigenetic changes that can potentially affect multiple generations.The study, published in theAmerican Journal of Stem Cells, suggest both parents contribute to the health status of their offspring — a common sense conclusion which science is only now beginning to demonstrate, says the study's senior investigator, Joanna Kitlinska, PhD, an associate professor in biochemistry, and molecular and cellular biology.“We know the nutritional, hormonal and psychological environment provided by the mother permanently influences organ structure, cellular response and gene expression in her offspring,” she says.“But our study shows the same thing to be true with fathers — his lifestyle, and how old he is, can be reflected in molecules that control gene function,” she says. “In this way, a father can affect not only his immediate offspring, but future generations as well.”For example, a newborn can be diagnosed with fetal (胎儿的) alcohol spectrum disorder (FASD), even though the mother has never consumed alcohol, Kitlinska says. “Up to 75 percent of children with FASD have biological fathers who are alcoholics, suggesting that preconceptual paternal alcohol consumption negatively impacts their offspring.”Advanced age of a father is correlated with elevated rates of certain diseases, and birth defects in his children.A limited diet during a father’s preadolescence has been linked to reduced risk of cardiovascular death in his children and grandchildren. Paternal obesity is linked to enlarged fat cells, changes in metabolic regulation, diabetes, obesity and development of brain cancer. Psychosocial stress on the father is linked to defective behavioral traits in his offspring. And paternal alcohol use leads to decreased newborn birth weight, marked reduction in overall brain size and impaired cognitive function.“This new field of inherited paternal epigenetics needs to be organized into clinically applicable recommendations and lifestyle alternations,” Kitlinska says. “And to really understand the epigenetic influences of a child, we need to study the interplay between maternal and paternal effects, as opposed to considering each inisolation.”12. What’s the message the writer conveys in the passage?A. Both parents contribute to the health status of their offspring.B. Father’s age and lifestyle are tied to birth defects.C. Father plays a more critical role in birth defects.D. Birth defects can potentially affect multiple generations.13. What can we infer from the example in Paragraph 5?A. FASD can only be diagnosed in a newborn whose father is addicted to alcohol.B. A newborn will not contract FASD if his mother has never consumed alcohol.C. A father’s lifestyle can negatively impact his offspring.D. Most children have biological fathers who are alcoholics.14. Which of the following situations is less likely to lead to children’s birth defects?A. Having a father with a limited diet.B. Having a father who is an alcoholic.C. Having an overweight father.D. Having a father with psychosocial stress.15. What will the research probably continue to focus on in the part that follows?A. The maternal epigenetic influences of a child.B. The ways to avoid negative paternal influence on children.C. The clinical application of the research findings.D. The interaction between maternal and paternal effects.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。

Growers, north ofSan Francisco, have begun pulling out of local farmers markets.CountyLineHarvest, which farms more than 30 acres inPetaluma, hasn’t had enough water to grow all the peppers, lettuces and other produce for a long time, according to a video on its Instagram page. Nearby farms arc saying the same, emphasizing (强调) the effect of theextendeddry periods.Californiagrows a third of theUnited States' vegetables and two-thirds of the nation's fruits and nuts. If dry weather prevents farmers from growing plants, that could lead to pushing up the price of food that's already starting to affect theU.S.economy.“Due to severe drought, for the first time in 21 years, we will not be able to grow this summer inPetaluma,"CountyLinesaid in its post.Drew Lerner, president of World Weather Inc. inKansas, saidCalifornia“missed the rainy season" and won't see much moisture (水分) over the next several months.A La Nina weather pattern in the Pacific pushed winter storms north and away from the state, leaving it with less moisture than usual. AsCaliforniagets most of its water from winter storms, little relief is expected before October.That has left growers such as Shao Shan Fann in a bind. The business can’t offer the selection of Asian vegetables and Bay Area staples it usually grows at its Bolinas location, according to its website.Nearby, Green Valley Community Farm has access to only about 5% of the water it usually relies on, owner David Plescia said. He’s looking for new land with enough water to use, and also has a permit in the works to grow cannabis to make up for the lost income. If it doesn’t make it, he’ll leave the fields empty.“It’s part of our generation’s cross to bear, figuring out how to run small — or medium-scale farm businesses in this kind of atmosphere of highly variable rainfall,” Andrew said.4. What does the underlined word “extended” in the second paragraph mean?A. Hot.B. Short.C. Long.D. Wonderful.5. Which is the result if the dry weather stops famers from planting crops?A. Theincreaseinthe priceof food.B. The growth of economy inU.S.C.Lessmoisture than usual.D. The low price of Asian vegetables.6. From what Andrew said, we can infer (推断) all of the following statements EXCEPT that________.A. The climate is not very goodB. It is part of the burden for people of his generationC. It is hard for him to run his farm businesses insuch bad climateD. He is sure that the serious drought will come to an end soon7. What does the passage mainly talk about?A. How do the famers run businesses inCalifornia.B. How does the owner look for new land with enough waterC. California farmers facing drought choose not to plant crops.D. The farm economy of theUnited Stateshas changed a lot.CEvery day in the United States animals are beaten, ignored, or forced to struggle for survival. Left in poor conditions with no food or water, they have little hope as they live out their days without the mercy they deserve. Some are found and rescued, given the chance to experience how great life and humans can be; others aren't so lucky. To grow as a nation, we must fight for these abused(受虐待的) animals’ rights and seriously punish heartless owners.One of the first steps in protecting animals and creating effective cruelty laws is to know what animal cruelty actually is. There are two categories: passive cruelty and active cruelty. The first involves acts of omission, meaning the abuse happens as a result of ignorance or lack of action. Passive cruelty might seem less serious, but that is not the case; it can lead to terrible pain and suffering, and finally death. Examples include starvation, inadequate shelter in extreme weather conditions, and the failure to get medical care. Passive cruelty is sometimes due to the owner's ignorance, so many animal control officers will first try to educate ignorant owners on how to properly care for animals before giving them a citation(传票) or putting them in prison.Active cruelty, on the other hand, is more well-known and disturbing. Sometimes referred to as non-accidental injury, this type of abuse involves purposeful harm on an animal in order to feel more powerful or gain control. Active cruelty against animals should be taken very seriously, since it can be a sign that a person has serious psychological issues and may commit more acts of violence---possibly against humans.It is hard to tell just what drives people to harm innocent animals. Most animal abusers find some sort of achievement or power in torturing a victim that they know can't fight back. While not all animal abusers become serial killers, it is important to take every case seriously.As a nation we need to make it our right to come together and ensure the safety of our beloved pets. As Margaret Mead once said, “Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.”8. What is the first step to do with the passive cruelty abusers?A. To throw them into prison.B. To bring the case to the court.C. To teach them how to treat animals.D. To give them a strong warning.9. We can learn from Para.3 that active cruelty ______.A. is actually a sign of power or controlB. has been taken seriously in the nationC. may lead to serious psychological problemsD. may cause acts of violence against humans10. What is the author’s attitude towards animal cruelty?A. Uncertain.B. Doubtful.C. Concerned.D. Pessimistic.11. The author wrote this passage to ______.A. warn those heartless pet ownersB. tell people the harm of animal crueltyC. explain the reasons why people harm animalsD. call on people to fight for the abused animalsDWith their tiny brains and excellent ability to memorize nectar locations, honeybees are a favorite model organism for studying learning and memory. Such research has indicated that to form long-term memories—ones that last a day or more—the insects need to repeat a training experience at least three times. By contrast, short-and mid-term memories that last seconds to minutes and minutes to hours, respectively, need only a single learning experience.Exceptions to this rule have been observed, however. For example, in some studies, bees formed long-lasting memories after a single learning event. Such results are often regarded as circumstantial anomalies, says MartinGiurfa of the University of Toulouse. But the anomalous findings, together with research showing that fruit flies and ants can form long-term memories after single experiences, aroused Giurfa’s curiosity. Was it possible that honeybees could reliably do the same? Giurfa reasoned that the ability to form long-term memories might depend on the particular type of bee and the experience. Within a honeybee colony, there are nurses, who clean the hive and feed the young; guards, who patrol and protect the hive; and foragers, who search for nectar.While previous studies have tested bees as a whole, Ciurfa and his colleagues focused on foragers, tasking them with remembering an experience relevant to their role: an odor associated with a sugary reward.The researchers observed that a single exposure to a reward-paired odor was enough for most forager bees to remember that specific odor the following day. Many foragers could even remember the odor three day later.The results do not mean that all prior research was wrong, says André Fiala of the University of Göttingen. “People have done the experiments in a different way.” Still, the new results do show that “the commonly held belief that one needs multiple training trials to achieve long-term memory is not always true,” he says, and this “really advances the field.”12. What does the author want to tell us through Paragraph 1?A. A model for memory research.B. The classification of memories.C. New research on learning and memory.D. Previous findings on memory formation.13. Which factor might influence a bee’s memory of an experience, according to Giurfa’s research?A. Whether the bee's role is related.B. Whether the bee is introduced or native.C. How often the bee repeats the experience.D. How long the bee is exposed to the reward.14. What is Andre Fiala’s attitude towards the new results?A. Doubtful.B. Favorable.C. Intolerant.D. Unclear.15. Which of the following is a suitable title for the text?A. Learning and Memory: How Honeybees RememberB. Honeybee Memory: Honeybee Knows What to DoC. Honeybees Remember after Just One LessonD. Honeybees Use Memory for Communication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。
