平凡的世界路遥第二天窗户纸刚发亮，少平就悄悄地爬起来。
他现在一心想的只是要找到那位没见过面的亲戚。
赶到北关的时候，天已经大亮了。
他看见路边水井旁边有个正用辘轳汲水的老头，便试着走过去向这老头打听他的亲戚马顺。
老头向他指了指阳面土坡上的一个院子，说:“就住在那里，我们原来是一个生产队的。
”少平的心咚咚地跳着，兴奋地爬上了那个小土坡。
当少平向他的亲戚说明他是谁的时候，没见过面的远门舅舅和妗子算是勉强承认了他这个外甥。
马顺看来有四十岁左右，一张粗糙的大脸上，转动着一双灵活的小眼睛。
他不冷不热地打量了他一眼，问:“你就这么赤手空拳跑出来了？”“我的行李在另外一个地方寄放着，我想……”少平还没把话说完，他妗子就对他舅恶狠狠地喊叫说:“还不快去担水！”少平听声音知道她是向他发难，他于是立刻说：“舅舅，让我去担！”说话中间，他眼睛已经在这窑里搜寻水桶在什么地方。
水桶在后窑里！他没对这两个不欢迎他的亲戚说任何话，就过去提了桶担往门外走。
马顺两口子大概还没反应过来，他就已经到了院子里。
孙少平一口气给他的亲戚担了四回水，那口大水瓮都快溢了。
马顺两口子的脸色缓和下来，似乎说:这小子看来还精着哩！他舅对他说:“你力气倒不小，我们大队书记家正箍窑，我引你去一下，看他们要不要人。
你会做什么匠工活？”“什么也不会，只能当小工。
”少平如实说。
“……我记得前两年老家谁来说过，你不是在你们村里教书吗？小工活都是背石头块子，你能撑架住？”“你不要给人家说我教过书……马顺把少平引到他们大队书记的家里。
书记看这个“小工”身体还不错，问马顺:“工钱怎么说？”“老行情都是两块钱……”他舅对书记说。
书记嘴一歪，倒吸了一口气。
“一块五！”少平立刻插嘴。
书记“扑”一声把吸进嘴里的气吐出来，然后便痛快地对少平说:“那你今天就上工！”他先问最迫切的问题:“能不能住宿？”“能！就是敞口子窑，没窗户。

2019-2020学年洛阳市东方高级中学高三英语第四次联考试题及答案解析第一部分阅读（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AYou might not expect it, but cows are a large source of the greenhouse gases that are driving climate change. Cows produce lots of methane by breaking down the grass, Now scientists have shown that the pollution from cows canbe reduced by adding a little seaweed to their food.Scientists first discovered that seaweed could help control methane from cows several years ago. But this work was done in a laboratory, there were many questions about whether the idea could work in real life.In the lab studies, the cows were given quite a bit of seaweed, and they would cause losing weight. That wasn't helpful, since cows are often sold by weight. It also wasn't clear if the seaweed would stop working if it was used for a longer period of time.Now, scientists from the University of California, Davis have answered several of these questions.The researchers studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood, which allowed the scientists to measure the methane that the cows were giving off. This time, they used a much smaller amount of seaweed, which they mixed with the cows' food.The results were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given, but even the worst-polluting cows produced 33% less methane.Over the five months, the scientists didn't see any signs that the cows' stomachs were getting used to the seaweed and starting to produce more methane again.Another surprise came when they looked at the weight of the cows. The cows that were fed seaweed gained just as much weight as the other cows, but they didn't need as much food.But there are still some big problems with the idea of feeding cows seaweed. For one thing, there's notadequateseaweed to feed all of the cows in the world. So farmers would have to figure out a way to grow lots of seaweed.A bigger problem is that for most of their lives, cows live in fields, where they eat the grass. That means there's no chance to feed them seaweed every day. These problems need to be taken seriously if the world isgoing to avoid the worst effects of the climate crisis.Still, it's true that something as simple as feeding cows seaweed can help reduce some of the pollution causing the climate crisis.1. Why did the scientists do the experiment on the farm?A. To control the amount of seaweed.B. To record the weight cows gained.C. To confirm the effect of seaweed in real life.D. To measure the amount of seaweed cows ale.2. The underlined word “adequate” means ________ .A. commonB. specialC. lackingD. enough3. The passage is written to ________ .A. appeal to people not to raise the cowsB. encourage people to plant the seaweedC. remind people of controlling cows' weightD. call on people to take actions to reduce the pollutionBNew Yorkis among the slowest cities during rush hour in the world, according to a report published in January. Crossing midtown by car is soul-destroying. The average speed is 4.7 miles per hour, not much quicker than a quick walk. But relief is in sight. On April 1st, state lawmakers agreed to introduce road charges, makingNew Yorkthe first big American city to do so. By next year vehicles will have to pay to enterManhattansouth of60th Street.The details of the new rule, including how much drivers will have to pay, how they will pay and how often they will pay, haveyet to be decided. A “traffic mobility review board" will be set up to work all this out. New Yorkers living in the fee zone who make less than $60,000 a year will be exempt (获豁免) . Other drivers, including motorcyclists, the city' s civil servants, disabled drivers and the trucking industry, all want discounts or exemptions, which might not be a good sign.If done right, road pricing could be expanded beyondManhattan.New Yorkcan learn from other cities.Singapore, for instance, which has had pricing for decades, adjusts prices regularly. It can also learn from mistakes.London, which rolled out its pricing in 2003, is only starting to charge on-demand car hires like Uber. Stockholm exempted too many vehicles, which caused a drop in revenues (收入) .Other cities considering road charges, includingLos Angeles, Philadelphia Portland,San FranciscoandSeattle, are watchingNew York. "We really have t1o make a good example," says Nicole Gelinas of the Manhattan Institute, aNew Yorkthink tank.4. What does the report find?A.New Yorkhas terrible road traffic.B.New Yorkoften introduces new laws.C. New Yorkers prefer walking to driving.D. New Yorkers face an increased cost of living.5. What can be inferred about the new rule from paragraph 2?A. It faces some potential problems.B. It has clear and detailed fee standards.C. It favors New Yorkers living in the fee zone.D. It fails to win a traffic mobility review board s approval.6. What doLondonandStockholmhave in common?A. They learn a lot fromSingapore.B. They have greatly increased revenues.C. They charge on-demand car hires heavily.D. They are bad examples of placing road charges.7. What is the best title for the text?A. How much does it cost to drive intoManhattan?B.New Yorkapproves road pricing forManhattanC. Drivers fear crossingManhattansouth of60th StreetD. Who will be exempt from road charges inManhattan?CBecoming famous is the dream of many, and Tian is getting closer to that dream.Tian, 30, is a white-collar worker inBeijing. On short video application Douyin, Tian has more than 2,000 fans. So far, she has received more than 50,000 likes on the Dubsmash-like app. On her page on Douyin, Tian shares everything, from her son’s daily activities, to her pet dogs, to little skits (段子) made up by her and her husband. “Making funny videos, and combining them with music is really interesting,” Tian said. “Of course, I make the videos for fun because it is quite relaxing.”China’s short video market has seen great growth, according to areport. The report said thatChina’s short video market was valued at 5.73 billion yuan ($900 million) in 2017, an increase of 184 percent. The industry value is expected to go up to the 30 billion mark in 2020. Companies like Tencent, Sohu and Iqiyi have all started providing short video content.“Short videos are popular because they are an addition to traditional audio and video content on the internet,” said Sun Jiashan with the Chinese National Academy of Arts.Fans say that the short videos help them “chill out” from a stressed-out lifestyle. “My favorite videos are all about pets,” said Zhou Na, a nurse inHefei, capital of East China’sAnhuiprovince. “After a whole day’s work, watching the 15-second videos makes me laugh, which reduces my pressure.”8. Why does Tian make short videos in Douyin?A. To get fun.B. To become a well-known person.C. To attract fans.D. To record her family’s routine.9. What’s Sun Jiashan’s opinion about short videos?A.

Famous for its mineral-rich mudflats, visitors rush to Boryeong in July to make themselves in mud, swim in grey pools and enjoy the party. There are even mudslides and a mud skiing competition for those who are seeking the extreme mud adventure!La Tomatina, SpainThe festival dates back to a parade in which some naughty teenagers knocked one performer off his stilts (高跷)and caused a fight of throwing vegetables accidentally. It was once banned until 1957 when the locals held a protest with a funeral. They carried a coffin containing a huge tomato as bands played a funeral march. In the following decades, La Tomatina has become a popular event. If you join the event, be aware that you squash (压扁) the tomato before throwing it. Have a great time but avoid causing any injury.Dia de los Muertos, MexicoBeginning at the midnight of October 31 and lasting through November 2,it is a festival when families gather together to remember those loved ones who have died, aiming to help them on their spiritual journey.

One of the most endearing happened when she was teaching second grade.That year, she decided to plan something special for the children: a Mother’s Day tea. After all the preparations were made for it, each child took home an invitation.Nancywas surprised and relieved to see that every mother was planning to attend. She even invited her own mother.Finally, the day arrived. That afternoon, each child lined up at the classroom door expecting the arrival of his or her mom. As it got closer to starting time,Nancylooked around and her eyes quickly found Jimmy. His mother hadn’t shown up and he was looking upset.Nancytook her mother by the hand and walked over to Jimmy. “Jimmy,”Nancysaid, “I have a bit of a problem here and I was wondering if you could help out. Since I’m going to be really busy today, I was wondering if you could keep my mother company.”Nancy’s mom and Jimmy sat at a table with two other mother-child pairs. Jimmy servedNancy’s mom her treats, presented her with the giftNancyhad made, and pulled out and pushed in her chair, just as they had practiced the day before. WheneverNancylooked over, her mom and Jimmy were in deep conversation Ten years later,Nancywas at a high school to take a senior class on a field trip, and there was Jimmy. On the way back,Nancyhad the students complete an evaluation form of their trip. She collected and checked the forms one by one.When she came to Jimmy’s evaluation page, he had written, “Remember our Mother’s Day tea we had in second grade, Mrs. Marra? I do! Thanks for all you did for me, and thank your mother, too.”As they began unloading at the school, Jimmy made sure he was the last one to go.Nancytold him she really enjoyed what he had written. He looked rather embarrassed, mumbled (咕哝) his own thanks, and then turned to walk away. As the bus driverbegan pulling the bus away, Jimmy ran back and knocked on the bus door. He jumped back on board and gaveNancya big hug. “Thanks again, Mrs. Marra. No one even knew my mom didn’t make it that day!”She ended her workday with a hug from a teenage boy who had probably stopped hugging teachers yearsago.4. Why was Jimmy paired withNancy’s mother?A. Nancy was too busy to spend time with her.B. Jimmy’s mother didn’t come to the event.C. Nancy wanted Jimmy to get to know her.D. Jimmy could get along well with her.5.

Nearly 700 million people get a mosquito-borne illness each year, which results in over one million deaths. Humans experience continuous pressures from disease-carrying mosquitoes in many parts of the world, so we have to find ways to fight against those insects because they keep getting scarier.Even though DEET remains the most commonly used, and most powerful, mosquito repellent ever developed, scientists are actively pursuing effective products based entirely on plant oils. While DEET is an effective contact repellent, many people dislike the oily feel and smell on their skin, and sometimes some people are sensitive to it. Consumers are always interested in alternatives to DEET and other synthetic repellents, so there are numerous natural repellents on the market.In his lab atIowaStateUniversity, Dr. Joel Coats and his team have successfully tested these repellents against three species of dangerous mosquitoes. The first group of the new repellents act through the air. These chemicalshave a vapor action that provides protection, and they are called “spatial” repellents, since they act through space. These are potentially most useful in backyards, parks, and houses. The other group are the classic ones that stop insects from standing on a treated surface, such as human skin, clothing or tents; collaborators at the USDA-ARS and BioGents have conducted testing with humans to confirm the effectiveness and identify the very best ones.The new repellents were designed and made from the natural materials in plant essential oils. They maintain many of the advantages of the natural repellents: They are fully biodegradable, with no ecological concerns or environmental wastes, and generally considered safe like the thousands of types of plant essential oils used in the flavor and perfume industries. However, thorough testing will be conducted to determine if they are truly non-poisonous because there is still no enough evidence.8. What does the author mainly want to show in paragraph 1?A. The way mosquitoes spread disease.B. The high death rate of mosquito-borne illness.C. The difficulty of fighting disease-carrying mosquitoes.D. The urgency of finding tools to fight against mosquitoes.9. What is a disadvantage of DEET?A. It won’t be effective for long.B. It can’t be applied universally.C. It causes discomfort to the users.D. It greatly harms people’s health.10. What can we learn about the second group of the new repellents?A. They can kill mosquitoes indirectly.B. They are mainly used in the open air.C. They are more effective on human skin.D. They can prevent mosquitoes from contacting users.11. What’s the author’s attitude to the new repellents?A. Subjective.B. Objective.C. Doubtful.D. Disapproving.DWhat about your emotions? How do they help you to understand what you are reading?In Jane Yolan'sOwl Moon,a girl explores with her father on a snowy night. She longs for this special night.And she's amazed when she sees an owl.Have you felt longing before? Amazement? Well, if you have, it helps you have a sense of agreement. When we can put ourselves inside a story we can understand it better. Our brain tellsus,"Oh, this girl's experience is a bit like mine."And boom! We can relate to her.But this skill is not born in us.So young kids have to learn it.Pictures and images help young readers to understand and recognize feelings.Readers feel joy when seeing the smiling faces of friends.They feel fear when turning the page to find a scary monster. They are just pictures,but the feelings are real. This skill, to understand the thinking and feeling of others, is what researchers call "theory of mind".For example, think about the faces of people and animals in stories. The Big Bad Wolf's scary teeth. The 'o' shape of a surprised character's mouth. Or big, wide eyes like the girl inOwl Moon.By noticing the faces,readers can start to figure out what it feels like to be that character.And that helps to figure out how people feel and think in real life.But most young readers don't go into deep,scary woods.And some may not go to the beach or play basketball.In the bookYo!Yes?two kids meet and play ball. The kids start the story on opposite pages.But as the story goes on,they get closer until they are together.Some young readers might not play basketball, but they can read the clues on the page to figure out how the kids are feeling.And some readers might not like the game,but they can feel excited for the characters because of how the characters look and move.12.

2019-2020学年杭州市东方中学高三英语第四次联考试卷及答案解析
2019-2020学年杭州市东方中学高三英语第四次联考试卷及答案解析第一部分阅读（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AIf you are sending a text message watching TV or listening to the radio, you may stop and give this your full attention. Multitasking shrinks (使.....萎缩)the brain? research suggests.A study found that men and womenwho frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, " Using mobile phones, laptops and other media devicessimultaneouslycould be changing the structure of our brains."Worryingly, the part of the brain that shrinks is involved in processing emotion. The finding follows research which has linked multitasking with a shortened attention span, depression , anxiety and lower grades at school.The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking e-mail, or speaking on the phone while watching TV and surfing the Internet. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingu-late cortex (ACC)(前扣带皮层).Scientists have proved that brain structure can be changed on exposure to fresh environments and experience.Other studies have shown that training—such as learning to play magic tricks or taxi drivers' learning the map of London―can increase grey matter densities (密度)in certain parts.Experts have also warned of the harmful impact technology can have on our memory and attention span. The University of California team conducted a survey of more than 18,000 people aged between 18 and 99，and found 20%had problems with memory. Researchers were shocked greatly by the 14 % of 18 to 39-year-old people who also worried about their memories.Multitasking may shorten attention span, making it harder to focus and form memories, the researchers said, adding that youngsters may be particularly affected by stress.1. The underlined word " simultaneously" in Paragraph 2 means "________，"A. on one's ownB. at no timeC. at the same timeD. by accident2. All of the following are possible effects of multitasking EXCEPT________ .A. saving timeB. a shortened attention spanC. lower grades at schoolD. depression and anxiety3. Which ofthe following can be the best title of this passage?A. Media multitasking is becoming more popularB. Multitasking shrinks the brainC. Multitasking may shorten attention spanD. People are worried about their memories.BThere is no such thing as a “safe" level of drinking, with increased consumption of alcohol associated with poorer brain health, according to a new study.In an observational study, which has not yet been peer-reviewed, researchers from the University of Oxford studied the relationship between the self-reported alcohol intake of some 25,000 people in the UK, and their brain scans. The researchers noted that drinking had an effect on the brain's gray matter-regions in the brain that make up "important bits where information is processed," according to leadauthor Anya Topiwala, a senior clinical researcher at Oxford.“The more people drank, the less the volume of their gray matter,“ Topiwala said via email. "Brain volume reduces with age and more severely with dementia(痴呆症).Smaller brain volume also predicts worse performance on memory testing,“ she explained. "While alcohol only made a small contribution to this(0. 8%), it was a greater contribution than other "modifiable" risk factors," she said, explaining that modifiable risk factors are “ ones you can do something about, in contrast to aging.”The team also investigated whether certain drinking patterns, beverage types and other health conditions made a difference to the impact of alcohol on brain health. They found that there was no "safe" level of drinking-meaning that consuming any amount of alcohol was worse than not drinking it. They also found no evidence that the type of drink— such as wine, spirits or beer—affected the harm done to the brain. However, certain characteristics, such as high blood pressure, obesity or binge-drinking, could put people at higher risk, researchers added.The risks of alcohol have long been known：Previous studies have found that there's no amount of liquor, wine or beer that is safe for your overall health. Alcohol was the leading risk factor for disease and premature death in men and women between the ages of 15 and 49 worldwide in 2016, accounting for nearly one in 10deaths, according to a study published in The Lancet in 2018.“It has been known for decades that heavy drinking is bad for brain health," Sadie Boniface, head of research at the UK's Institute of Alcohol Studies, said via email. "We also shouldn't forget alcohol affects all parts of the body and there are multiple health risks. ”4. What is the function of gray matter?A. Control the mount of alcoholB. Process informationC. Scan the brainD. Predict the performance on memory5. Which is NOT true in the following statements according to the study?A. Drinking alcohol is worse than not drinking.B. With people getting older, brain volume reduces.C. Alcohol was the major risk factor for disease and premature death.D. The less people drink alcohol, the more the volume of their gray matter.6. Which is one of the "modifiable" risk factors?A. SmokingB. AgingC. DeathD. Disease7. What is the main idea of the text?A. The mount of alcohol is not related to people's health.B. People drinking alcohol do harm to their brain health.C. People drinking alcohol lead to dementia.D. Theresa great deal of liquor, wine or beer that is safe for health.CHow much do consumers care about the carbon footprint of the products they buy? Would they care more if the goods were labeled with emissions（排放物）data?Does it matter at which stage in the lifecycle of a product the carbon is emitted? Research published in the International Journal of Environmental Policy and Decision Making offers a way to find out．Study participants view a carbon footprint label as similar to labels that have appeared on some existing products．The label shows the carbon dioxide emissions connected with their production, transportation, usage and disposal（清理）, thus showing the buyer the likely effect on climate change of buying a particular product．In the first group of studies, the research team proved that carbon emissions and a carbon emissions label would indeed play a role in consumer product decisions, although not as great a role as price．In a second set of studies, the team found that emissions connected with usage were most important to consumers followed by thetransportation and disposal stages．The carbon footprint of the producing process was considered less important to consumers than the other stages in the product's lifecycle because it is outside the consumer's control．That is, the participants felt they were less responsible for carbon emitted during producing process．Consumers value recycling a product, but the researchers found that, overall, the consumers would preferproducers to offset（补偿）carbon emissions rather than having toaddressthe problem directly themselves．Consumers are increasingly concerned with climate change problems, and already carbon labeling is appearing on some products．"We find that participantsnot only take the carbon label into account when making product decisions, but they want detailed information on the label," the researchers explain．They suggest that companies should prepare for how carbon emissions labels might affect future consumer choice．8. Which of the following most affects consumer's choice?A. Labels．B. Price．C Packaging． D. Carbon footprint．9. About the carbon dioxide emissions in the product's lifecycle, which stage do consumers care most?A. Usage stage．B. Transportation stage．C. Disposal stage．D. Producing stage．10. Which of the following can best replace the underlined word "address"?A. Look into．B. Point out．C. Deal with．D. Run into．11. What can be inferred from the last paragraph?A. Companies should take carbonemissions more seriously．B. All products have been labeled with carbon emissions data．C. Producers will attach less importance to carbon emissions labels．D. Products labeled with carbon emissions data will have poor sales．DA nurse has fulfilled (实现) a promise she made to her patient four years ago to one day attend her daughter's graduation from nursing school.Edina Habibovic, 22, graduated from Chamberlain University's College of Nursing in 2020. Her mother, Sevala Habibovic, 46, died in2017 after a two year fight with breast cancer.“I thought the medical field wasn't for me. Then, my mom got sick and I had all the experience going in and out of the hospital, ” Edina toldGood MorningAmerica. “When my mom passed away, I thought, ‘I want todothis.’”she said.Sanja Josipovic, who at the time worked as a home health nurse with Northwestern Medicine in Winfield, Illinois, cared for Sevala inside her home. They often chatted and shared the latest news with each other over six months of care.“She was most worried about Edina because she was young and hadn't finished school yet, ” Sanja said. “We are like sisters; we care about and trust each other. She was a powerful and strong minded woman. She wasn't scared to die; she was just worried about her kids and husband.”Edina said her mother lived for being with her family and taking care of people. “When Sanja was working, my mom would still try to make her something to eat, no matter how sick she was, ” Edina added. When Sevala's life was coming to an end, she asked Sanja to take her place at her youngest daughter's nursing school graduation. “That was the only thing she was going to miss. Edina's graduation, ” said Sanja, who is a mother of three herself. She agreed.Due to COVID -19, there was no graduation or pinning ceremony. Edina's manager at Marianjoy Rehabilitation Hospital decided to host a pinning ceremony for her and have Sanja present the pin. “Sanja has fulfilled her promise, ” Edina said.Edina and Sanja are now caring for patients alongside one another as colleagues at Marianjoy.12.

However, wolves have a softer, more social side, one that has been embraced by a heart-warming new initiative.In a bid to save some of Europe’s last wolves, scientists have explored the willingness of these supposedly fierce creatures to help others of their kind. Female wolves, the scientists have discovered, make excellent foster parents to wolf cubs that are not their own. The study, published in Zoo Biology, suggests that captive-bred wolfcubs(幼兽)could be placed with wild wolf families, boosting the wild population.The gray wolf was once the world’s most widely distributed mammal, but it became extinct as a result of widespread habitat destruction and the deliberate killing of wolves suspectedof preying on livestock. Fear and hatred of the wolf have since become culturally rooted, fuelled by myths, fables and stories.In Scandinavia, the gray wolf is endangered, the remaining population found by just five animals. As a result, European wolves are severely inbred and have little geneticvariability（变异性）, making them vulnerable to threats, such as outbreaks of disease that they can’t adapt to quickly. So Inger Scharis and Mats Amundin of Linkoping University, in Sweden, started Europe’s first gray wolf-fostering program. They worked with wolves keptat seven zoos across Scandinavia. Eight wolf cubs between four and six days old were removed from their natural parents and placed with other wolf packs in other zoos. The foster mothers accepted the new cubs placed in their midst.The welfare of the foster cubs and the wolves’ natural behavior were monitored using a system of surveillance cameras. The foster cubs had a similar growth rate as their step siblings in the recipient litter, as well as their biological siblings in the source litter. The foster cubs had a better overall survival rate, with 73% surviving until 33 weeks, than their biological siblings left behind, of which 63% survived. That rate of survival is similar to that seen in wild wolf cubs. Scientists believe that wolves can recognize their young, but this study suggests they can only do so once cubs are somewhere between three to seven weeks of age.If captive-bred cubs can be placed with wild-living families, which already have cubs of a similar age, not only will they have a good chance of survival, but they could help dramatically increase the diversity of the wild population, say the researchers. Just like the wild wolves they would join, these foster cubs would need protection from hunting. Their arrival could help preserve the future of one of nature’s most iconic and polarizing animals.4. What’s the theme of the passage?A. Giving wolf cubs a new lifeB. Foster wolf parents and foster cubsC. The fate of wild wolvesD. Changing diversity of wild wolves5. Which of the following flow chart best demonstrates the relationship between the wolves?A. B.C. D.6. Which of the following statements is true?A. Female wolves are willing to raise wolf cubs of 3 to 7 weeks old.B. Foster cubs are accepted by foster parents and are well bred.C. Man’s hostile attitude towards wolves roots in myths, fables and stories.D. Foster cubs and their biological siblings have similar growth rate and survival rate.7. What’s the purpose of the research?A. To help wolves survive various threatsB. To improve wolves’ habitat and stop deliberate killingC. To save endangered wolves by increasing their populationD. To raise man’s awareness of protecting wolvesCI’ve long believedthat positive living isn’t about being optimistic every minute of every day. That kind of permanently happy state can’t be the goal, because it’s impossible to achieve.It turns out that psychological research finds true happiness comes from authentic positivity, and authentic positivity comes from emotional flexibility.Being flexible emotionally means being open to the full range of emotional experiences, including the challenging ones like anger, disappointment and sadness. Emotional flexibility means being able to shift behaviors and mindsets to meet different situational needs, and adapting when circumstances change.However, emotionally flexible people are not chameleons (变色龙) whose outlook changes based on which way the wind is blowing. Instead, emotional flexibility is a skill that helps people judge the complexities of daily life, and stick to their deeply held values.I’ve learned a new word that I’d like to share with you: Eudaimonia (幸福感). Eudaimonia is the opposite of hedonism (享乐主义), the idea that happiness comes from the constant pursuit of pleasure and avoidance of pain. Eudaimonia, by contrast, encourages us to pursue meaning and authenticity, growth and honest joy. Both are philosophical approaches to happiness, and recent psychological thought is leaning toward eudaimonia as a more sustainable, satisfying model.Eudaimonia was first mentioned by Aristotle, who got the term from the Greek word “daimon,” which means “true nature.” Tome, walking a positive path means accepting that we each have positive true nature and permanent goodness. What we learn from the concept of eudaimonia is that we are best equipped to realize this nature when we are emotionally honest and flexible.8. What is the author’s belief?A. People should live alone.B. People can’t always be happy.C. People can’t always achieve their goals.D. People should pursue true achievements.9. What do enmotionally flexible people commit themselves to?A. Their strongly believed values.B. Their different needs.C. Permanent happiness.D. The pursuit of hedonism.10. How can people gain eudaimonia according to the author?A. By being honest to others.B. By changing true nature.C. By keeping realstically optimistic.D. By pursuing pleasure constantly.11. Which of the following is a suitable title for the text?A. What is the meaning of eudaimonia?B. What should we do to keep positive?C. How can we keep happy forever?D. Why can’t people be happy all the time?DAt Aizo Chuo Hospital in Japan, employees greet newcomers, guide patients to and from the surgery area, and print out maps of the hospital for confused visitors. They don’t take lunch breaks or even get paid. Why? They’re robots!Robots have long worked in factories, helping to build cars and electronic appliances. But today’s robots don’t just do the jobs of people－they actually look and act a lot like people.Kansei, arobot from Japan, has a plastic face covering 19 movable parts. The robot can make 36 facial expressions in response to different words. Kansei shakes in fear at the word “war” and smiles when it hears the word “dinner”.Researchers in Europe are going even further with iCub, a “baby” robot. They are teaching it to speak and hold conversations.The ability to interact is crucial for robots that will one day work closely with humans says robotics professor ChrisAtkeson. “ This will require robots to understand what you say and how you are feeling and respond with appropriate emotions, ” he told WR News.Japanese scientist Minoru Asada agrees. He is building a robot called CB2 that acts like a real baby. “ Right now, it only goes, ̒Ah, ah. ̓But as we develop its learning function, it will start saying more complex sentences and moving on its own, ” Asada says. “ Next-generation robots need to be able to learn and develop by themselves.”Intelligent robot will become more important in the future, as populations age and the number of human workers declines in many countries. “ We’re going to have many more old people and not enough young people to care for them,” says robot researcher Matthew Mason. “ Technology can help the old people live at home longer, instead of going to nursing homes.”12. According to the passage, what jobs have robots already performed?A. Giving advice, answering customer questions and planning events.B. Producing factory goods, building cars and greeting customers.C. Greeting customers, producing factory goods and performing surgery.D. Building cars, driving passengers and providing directions.13. The second paragraph in this passage is mainly about?A. To explain how a robot works.B. To define what a robot is.C. To describe the functions of modern robots.D. To predict the future uses of robots.14. How does the Kansei robot react on the word “fire”?A. Use languages to warn nearby humans.B Back up its memory files.C. Activate an automatic fire alarm.D. Produce a worried look on his face.15. In Asada’s opinion, the next step for robots will be to develop_______.A. the ability to learn independentlyB. the ability to understand human commandsC. the capacity to interact with humansD. the willingness to work together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。

A 34-year-oldUSman recently ended up in hospital after eating a Carolina Reaper—the spiciest chili in the world. After taking just a single bite of one, the man suffered from serious headaches in the following few days, reported BBC News.In fact, reports of stomachache and headache caused by eating spicy food are not something unusual. But if chilies are harmful, why is it that human beings are the only animals to eat this vegetable? According to the website Huanqiu, about 600 million Chinese people—almost half of the national population—are chili eaters. So what makes people love chilies so much? The human body reacts to the burning feeling that comes from eating chilies by releasing natural chemicals that “produce a sense of happiness” , noted BBC News.And the benefits go even further than just personal enjoyment. A survey conducted by the Chinese Academy of Medical Sciences found that the death rate of those who eat spicy food once or twice a week is 10 percent lower than those who eat it less than once a week. The number decreased to 14 percent for those who eat spicy food six to seven times a week. And another study done by theUniversityofVermontcame to a similar conclusion. “The data encourages people to eat more spicy food to improve health and reduce death risk at an early age,” Liu Qi, a nutritionist at the Harvard TH Chan School of Public Health, told BBC News.Chilies have anti-cancer quality and the ability to increase our metabolism (新陈代谢). So, don't worry if you love spicy food. It seems that chilies are actually good for us—except for the Carolina Reaper, perhaps.4. The example of a 34-year-old American is mentioned in Paragraph 1 to prove ________.A. chiliescan be beneficialB. chilies are popular inAmericaC. chilies can be dangerousD. serious headaches can be dangerous5. Eating chilies gives people a sense of happiness by_______.A. decreasing death rateB. releasing natural chemicalsC. curing serious headachesD. providing enough nutrition6.

The more chilies you eat, the healthier you are.D. Chilies have anti-cancer quality but it can't increase our metabolism.7. The writer wrote the passage to ________.A. warn people of the dangers of chiliesB. ask people to eat Carolina ReaperC. encourage people to eat more chiliesD. tell people the benefits of chiliesCThe grocerystore might not be your favorite place to visit when you're at home, but is it ever fun when you're in another country? Honestly speaking, they're one of those strange little destinations that I like to sniff out everywhere I go, much as other travelers head toward clothing stores, libraries, coffee shops or galleries.The greatest beauty of the grocery store –– whether it's a supermarket or a tiny shop –– is that it gives you a glimpse into what local people buy to cook their own meals. This offers clues into their lifestyles and preferences, and into the agricultural and cooking practices of the country. I stare at the strange fruits and vegetables, the seafood, the cheese, the spices, the bread, and oh, the chocolate...always the chocolate!Being the environmental nerd（呆子）I am, I like paying attention to packaging, which can reflect people's attitudes towards environmental protection. Italy, for example, has a habit of requiring customers to bag their fruits and vegetables in plastic for weighing, while Sri Lanka leaveseverything loose in bins. In Brazil, everything is prepackaged in a layer of plastic.People in grocery stores tend to be friendlier. They smile, say hello, and sometimes ask questions, which can lead to great conversations. I had a further discussion with a teenaged cashier in Sri Lanka, over which bag of crunchy（松脆的）mix to buy. He insisted that the one labeled “spicy” would be too hot for me, but I told him I was willing to risk it. He laughed and we ended up talking about my favorite Sri Lankan foods for ten minutes.It's interesting then to come home and look at one's own local grocery store through new eyes. What would a visitor think? What stands out, and what do the food displays say about us as a culture? You might be surprised by what you realize.8. According to the author, what is the key benefit of visiting foreign grocery stores?A. Learning to cook foreign dishes.B. Making friends with local people.C. Buying cheaper food and souvenirs.D. Knowing local people and the country.9. What does the author show by mentioning some countries in paragraph 3?A. People's special lifestyles.B. People's shopping habits.C. People's environmental awareness.D. People's packaging methods.10. What can we infer from paragraph 4?A. Sri Lankans know a lot about food.B. Grocery stores are good social places.C. Grocery stores vary in different countries.D. Sri Lankans like to give strangers suggestions.11. Which of the following shows the structure of text? (P: paragraph)A. B.C. D.DIt was very cold and I had been watching a homeless man make himself comfortable in a “shelter” on the river bank. His “shelter” was a tarpaulin (油布)tied to rocks to keep the wind from blowing it away. He had been living there for over a month. I never saw him with warm clothing or food. I knew what I wanted to do.When I told my parents what I wanted to do they werealarmed. They said I could be putting myself at risk, taking a box to a homeless person at night! But I knew, in my deep heart, that I would be safe.I got a box. My parents watched as I added warm gloves, a heavy blanket ... into the box until it was full! Then, I put a Christmas card on top.

"As one of four children in a migrant（移民）farming family from Mexico, Jose - who didn't learn English until he was 12 years old - spent much of his childhood traveling with his family from Mexico to southern California each March, then working northward to the Stockton area by November, picking strawberries and cucumbers at farms along the route. They would then return to Mexico for Christmas and start the cycle all over again in the spring. "Some kids might think it would be fun to travel like that,“ Jose laughed, "but we had to work”.After graduating from high school, Jose was admitted into the University of the Pacific, In 1987, he accepted a full-time job with Lawrence National Laboratory. In 2001, Jose joinedtheJohnson Space Center, where he came face-to-face with Franklin Chang-Diaz.“We actually had common experiences —asimilar upbringing, the same language issues. That built up my confidence. Any barriers that existed, he had already overcome them.” Jose smiled. "Now it's my tum!,,“NASA rejected me not once, not twice, not three times but 11 times. It wasn't until the 12th time that I got selected, he said. Jose was selected as part of the 19th class of astronauts in 2004. He circled the globe 217 times but remains a down to Earth guy.Jose Hernandez received the 2016 National Hispanic Hero Award and he continues his long history in the field of engineering and space.4. What made Jose determined to be an astronaut?A. The influence of Astronaut Corps.B. The success of Franklin Chang-Diaz.C. His interest in science and engineering.D. The experience of working in the field.5. What can we learn about Jose as a child?A. He did much farm work.B. He travelled a lot for fun.C. He hated learning English.D. He obeyed his family in everything.6. How did Jose feel when he met FranklinChang-Diaz personally?A. Inspired.B. Valued.C. Relaxed.D. Puzzled.7. What can be a suitable title for the text?A. Climb over BarriersB. Reach for the StarsC. Work the Hard WayD. Learn from Your PastCIn Australia, plenty of wild things can bite or sting(刺伤) you. Strangely enough, one of them is a tree. Now scientists have figured out what makes the tree’s sting so bad.The rainforests of eastern Australia are home to a stinging tree known as Dendrocnide. Many people callit the gympie-gympie tree—a name given to the tree by native Australians. It’s covered with sharp, needle-like hairs that carry poison. If you touch a gympie-gympie tree, you won’t forget it anytime soon. The pain can stay with you for hours, days or weeks. In some cases, it’s been reported to stay for months.Scientists have long looked for the source of this powerful sting. Now researchers at the University of Queensland have discovered what makes this stinging plant so painful. After carefully studying different kinds of gympie-gympie trees, the scientists were able to separate out different chemicals that the trees produce. This allowed them to identify a group of chemicals that they believed was responsible for the pain.The researchers created artificial versions of these chemicals, which they call “gympietides”. Sure enough, when the scientists injected mice with gympietides, the mice licked(舔) at the places where they’d been injected, indicating that they hurt in those places. When the scientists studied the way gympietides were built, they found that they formed a knot-like shape. The shape makes the chemicals very stable, which helps explain why the pain stays so long.The knot-like shape of the gympietides was similar to the shape of poisons produced by poisonous spiders and cone snails. The scientists were surprised to see three very different kinds of life all using similar poisons. Spiders and cone snails carry poisons because they catch food by stinging other creatures. It’s not clear howstinging helps the gympie-gympie tree.Though the tree’s sting may stop some animals from eating it, it doesn’t stop all animals. Beetles and pademelons (small s of the kangaroo) are able to eat the plant without trouble.8. Why is a touch on the stinging tree unforgettable?A. Because it has so unusual an appearance.B. Because it is extremely rare in existence.C. Because touching it creates a quite strange feeling.D. Because the pain caused by it doesn’t go away quickly.9. What do scientists fail to find out about the stinging tree?A. How it produces poisons.B. What poisons it produces.C. How it benefits from the sting.D. The consequences of its sting.10. What does the text imply about the stinging tree?A. It produces the same poisons as spiders.B. Poisonous as it is, it also has natural enemies.C. Animals are wise enough to stay away from it.D. Only one chemical in it causes pain to the toucher.11. What’s the best title for the text?A. Scientists Discover Stinging Tree's SecretB. Caution: Stinging Tree Can Bite and Poison YouC. Scientists Discover a Strange Species in AustraliaD. Effective Ways to Avoid Being Hurt by Stinging TreeDBeing a teacher is a rewarding career when it comes to changing lives, but it’s obviously one that comes with plenty of stresses and difficulties too.Seeking help for a child who is so obviously in need isn’t easy. Often, you feel ignored by the government. You feel upset that there isn’t anything you could personally do to help a needy and sensitive member of your class.That’s exactly how Chelsea Haley, aged 24 at the time, felt when she met fourth-grade student Jerome Robinson while working for Teach forAmericainLouisianafor the first time.The pair didn’t get off to the best start, with Jerome, the “problem child”, almost drivingChelseafrom teaching. But whenChelseaput her foot down and became determined to work more closely with Jerome, she learned the cause of his rude behavior: a bad home situation.Chelseawas eager to help Jerome, and realized that he needed more than just academic support.By 2016, a year after meeting him, Chelsea had adopted (收养) Jerome and his brother Jace.Adopting a child doesn’t come cheap, andChelseaspent all the money in her bank to see the process through.In her first few years of raising the boys, she lived on credit cards and postponed her student loan.AsChelsealived with her two adopted sons, she worked hard to repay her debts. She took on extra tutoring jobs outside of school hours, moved in with her parents, and even delivered groceries for cash. Along the way, she was learning how to be the best mom to Jerome and Jace, cooking for them and cheering them on at football matches.And now, just five years later,Chelseacan proudly say that she has paid off nearly $50, 000 of debt. Now that she’s finally out of debt,Chelseahas plans to buy a house and save up for the boys’ college education.“It allows me to focus on the boys’ future,” she said. “Saving money for them, and not spending it on my past.”12. What do we know from paragraph 4?A. Jerome’s family was less fortunate.B. The brothers were in the same class.C. When helping Jerome,Chelseafelt hopeless.D.Chelseagot along well with Jerome from the very start.13. What didChelseado to pay off her debts?A. Borrow money from her parents.B. Do part-time jobs.C.

But if you take the time to actually examine your anger instead of just “feeling” angry, you’ll have a better understanding of yourself. Knowing why you feel so angry can provide you with some surprising answers. These answers can enable you to suddenly grow spiritually and mentally.I can give you a personal example. I went to a meeting once and I was verbally attacked over an application I supported at my workplace. Various people went on and on about how terrible this system was and that it never worked. That didn’t bother me that much. I was used to that but one of the comments that was said was, “Your job is pointless.” This really upset meand at the time, I was ly furious(发怒地) with that comment.I was so angry and upset that they would treat me that way. Once I took the time to think about what was really making me so mad. I learned a lot. I realized that the comment was more truethan I wanted to admit. In the big scheme of things, my job was pointless. It wasn’t what I really wanted to be doing with my life and this was what frustrated me the most. Here I was pouring part of my heart and soul into a job I didn’t even really want to do. I was using it as a crutch(拐杖) because I didn’t have the confidence in myself to take the scary road towards what I really wanted to do. As soon as I realized that, a lot of my anger just melted away. I also realized that I needed to start focusing on what I really wanted to do.I now consider this incident as a great gift It got me back on track to moving in the direction I wanted to go with my life. I probably wouldn’t be where I am today if I hadn’t taken the time to figure out why I was really so angry.4. What made the author angry at the meeting?A. The system of the company was terrible.B. Someone said his job is insignificant.C. The policy of the company didn’t work.D. The application he supported was of no effect.5. What brought down the anger of the author?A.

S. of young people between the ages of 18 and 34. This generation is often called millennials (新千年一代). More than half of millennials in Los Angeles are bilingual (双语的), which means they speak more than one language.Maria Elena Burgos is cooking a Mexican breakfast. She says making Mexican food is just one of the many traditions in her home. Another is speaking Spanish to her children.“We want them to be bilingual. We want to keep the Spanish somewhere in their learning too, not only at home.”When Ms Burgos first came to the United States from Mexico, she learned English. She knew her children would learn English quickly. So she wanted them to speak Spanish at home and study the language at school.She says being bilingual will give them more opportunities in the future. Knowing Spanish also means the children can talk with their s in Mexico.“When we had our children, one of the decisions we as parents made was to name them with a name that was easily pronounced in English and Spanish.”Elizabeth wants to know her family’s culture.” “The culture-to go back to our roots because that’s part of who we are.”Monica wants to pass on the culture to her children“It’s nice to know our culture and then to be able to pass it onto our children and grand-children and everyone to let them know where we come from.”And, Monica says she does not speak only English and Spanish.

That was until a couple of weeks ago, when my kids gave me a present thatblew me away.For years now, I’ve been wanting to sell our home, the place where my husband and I raised our kids. But to me, this house is much more than just a building.In the front room, there’s a wall that has hundreds of pencil lines, marking the progress of my children’s growth. Every growth stage is marked in grey, with each child’s name and the date they were measured. Of all the objects and all the memories, it’s this one thing in a home that’s the hardest to leave behind. Friends I know have returned home after work only to discover their wall of heights has been freshly painted over. A new paint job wouldn’t normally be greeted by tears, but erasing that evidence of motherhood hurts more than it should. Our kids grow in so many ways, but the wall is physical evidence of their progress, right there for everyone to see. Over the years, I’ve talked about how much I would hate leaving that wall behind when I moved, even though the last marks were made 10 years ago when my kids stopped growing.So one day, while I was at work, my childrendecided to do something about it.They hired Jacquie Manning, a professional photographer whose work is about capturing (捕捉) the beautiful things in life, from clear lakes and skies to diamonds and ballgowns (舞会礼服).She came to our house while I was at work, and over several hours, took photos of the hundreds of drawings and lines, little grey fingerprints (手印), and old marks. Somehow, she managed to photograph all those years of memories perfectly. Afterwards, she put all the photos together into one image, transforming them into a beautiful history of my family.Three weeks later, my children’s wonderful gift made its way to me—a life-size photo of the pencil lines and fingerprints that represents entire lifetimes of love and growth.4. The underlined phrase in Para. I “blew me away” probably means “________”.A. attracted meB. surprised meC. accepted meD. refused me5. What does the house really mean to the author?A. A house.B. Buildings.C. An object.D. Memories.6. What surprised the friends I know after work?A. Finding the wall repainted.B. Erasing the fingerprints.C. Greeting them by tears.D. Leaving the wall unfinished.7. What is the best title for the text?A. Gift Made with LoveB. Buildings Made by ChildrenC. A Very Wonderful PaintingD. A Family HistoryCThermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, like a free lunch. But the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermae-lectrices that work just as well. The work could pave the way for greener car engines, and other energy-generating devices.“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist. He notes there are still a few more steps before these materials can become high-performing. However, he says, “This will be used in the not too far future.”Thermoelectrics are semiconductor devices placed on a hot surface. That gives them a hot side and a cool side. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.Researchers have produced thermoelectric materials with increasing ZTs. The record came in 2014 when Mercouri Kanatzidis came up with a tin selenide with a ZT of 3.1. Yet the material was too fragile to work with. “For practical applications, it’s a non-star-ter,” Kanatzidis says.Getting through that door will still take some time. The tin selenide the team makes is mixed with Na, creating a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.Zhao’s team is now working on making an n-type version. Once successful, researchers should have a clear path to making a new generation of super-efficient thermoelectric genera-tors. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial smelters toscavengesome of the 65% of fossil fuel energy that winds up as waste heat.8. The first paragraph wants to tell us________.A. The wide use of thermoelectric generatorsB. The devices of current thermoelectric generatorsC. The reason why researchers make cheap thermoelectricsD. The greener car engines that contribute to environmental protection9. How does Li-Dong Zhao feel about cheap thermoelectric generators?A. Indifferent.B. Optimistic.C. Critical.D. Worried.10. What do you know about the research in 2014 from paragraph 4 and 5?A. It was far from a success for practical applications.B. A tin selenide with a ZT of 3.1 can be easy to work with.C. Researchers made an “n-type” version to make working devicesD. A “p-type” material made from the tin selenide conducts negative charges11. What does the underlined word “scavenge” in the last paragraph mean?A. Recycle.B. Produce.C. Clean.D. Increase.DAccording to statistics published by the BPI (Buying Power Index) a couple of months ago, digital streaming (流媒体) now accounts for 80 percent of the music consumption in the UK. Despite the incredible growth ofonline streaming platforms like iTunes, Apple Music and Tidal over the past 15 years, a more traditional medium has also seen a return of interest and sales in the music industry. In 2020, almost one in five of all albums purchased in the UK is vinyl (黑胶唱片), and it has once again become the most popular physical musical medium.With digital streaming so easy and convenient, why are so many peopledrawn to traditional records? Some experts claim that vinyl is a physical medium for experiencing music, something tangible (有形的) to hold and own. For most people, having something tangible and interacting with it gives depth to the experience of music. Listening to an album and touching it the way the artist intended can make them feel more connected to the music and the artist. Records are physical products that can be not only displayed but also gifted, shared, traded and passed down through generations.Sound quality is another hot topic. A lot of music lovers feel that the analogue sound (模拟声音) vinyl offers is superior to modern digital audio, particularly with regards to the compressed formats streaming platforms use. There’s a common belief that old-school analogue audio has a warmer, fuller sound than digitised music. For vinyl followers, the very defect traditional recorders often have, such as the familiar crackle (劈啪作响) when the record starts, bring the music to life in a different way.There’s aritualisticaspect to vinyl that a lot of people are drawn to, too. The act of putting a record on—carefully removing the record from the sleeve, placing it on the record player and gently dropping the needle on the right groove (凹槽)—is a more assiduous (一丝不苟的), mindful way of engaging with music. When you’re listening to vinyl, you can’t tap abutton and go about your day while the streaming service provides hours of music. You need to stay close to the record player to move the needle and flip the record over.It’s clear that the vinyl interest is well underway, and vinyl records are truly making a comeback. In an increasingly digital society, there’s something to be said for analogue experiences. Perhaps one of the great things about being alive in the 21st century is our ability to have the best of both worlds—the timeless appeal of physical records alongside the easy access to vast music libraries that streaming offers.12. What are the statistics published by the BPI used to show?A. An increase in music consumption.B. The recovery of music industry.C. A comeback of a physical medium.D. The acceptance of online streaming.13. According to some experts, why does vinyl interest many people?A. It attracts people by its realistic feel.B. It offers simple access to different music.C. It shares a new way to enjoy music.D. It provides people with perfect sound effect.14. The underlined word “ritualistic” in Para.4 means something ______.A. Overlooked by society.B.
