2021届泰顺县育才高级中学高三英语二模试卷及答案
2021届泰顺县育才高级中学高三英语二模试卷及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIn Sweden, McDonald’s is building “bee hotels” on the back of its roadside billboards (广告牌) to help save the country’s decreasing bee population. It launched the campaign together with outdoor advertising giant JCDecaux. Six large wooden bee hotels, with drilled holes on the front, first appeared on the back of a north-facing billboard in Jarfalla in September.“Without pollination (授粉) from bees, a thirdof the food we eat would be threatened.” McDonald’s said. But it turns out that at least 30 percent of the country’s wild bee population is endangered, according to the fast-food chain. A big problem is that they lack places to live. Based on data released by Chalmers University of Technology, we know Sweden owns 274 species of bees, of which 37 species are bumblebees, and more than a third are decreasing or face the risk of decreasing. Their natural habitats have been damaged by factors including the changes of agricultural activities and fast urbanization (城市化). Fortunately, most bees are able to survive in urban habitats, like the bee hotels.Every McDonald’s authorized restaurant in Sweden will be allowed to order their own bee hotel billboards and design the messages by themselves, as the fast-food chain says. It is their hope that the number of hotels could grow to a greater extent in the near future. Great efforts in addition to that have been made by the company. On World Bee Day, May 20, it introduced “the world’s smallest McDonald’s”. McHive, which could function as an actual beehive (蜂箱). Designed by set designer Nilsson himself, the creation was sold for $10,000 at a charity fundraiser held for Ronald McDonald House Charities.Beehives can be found on the rooftops of some McDonald’s restaurants in Sweden, too. This took place in certain areas but is now followed by an increasing number of participants. More McDonald’s restaurants are making an effort to improve the living conditions of wild bees by removing the grass round their restaurants to grow flowers and plants instead.1. According to the passage, the challenge that wild bees are facing is ________A. the fast process of industry.B. the world's Large amount of trash.C. the rapid development of urbanization.D. the sharp growth of population.2. How does McDonald's help wild bees in Sweden?A. By providing shelters for bees.B. By offering food to bees.C. By advertising rescue activities.D. By putting up more billboards.3. What is the best title for the text?A. Wild bees in dangerB. The loss of bees’ habitatsC McDonald’s bee hotelsD. The protection of wild beesBFor centuries , tea has been used for far more than quenching thirst. Around the world people drink it to relax, reinvigorate and relieve, and it's something we need now more than ever.Even in the United States, a long coffee-dominated country, tea drinking is growing in popularity, with the country consuming 0.4 kilograms (14 ounces) of tea leaves per person a year compared with 0. 36 kilograms(12. 7 ounces) in 2007 according to the United Nations, as people switch away from soda，milk and fruit drinks.Scientists are beginning to look into just how tea might affect mood and cognition. Specifically, they're investigating whether its relaxing and refreshing effects are a direct biological outcome of the compounds in tea or whetherthey come from the context in which the drink is consumed—preparing your tea, choosing your favorite cup and sitting down for a brief break from the world. Or both.Drinking green tea has been found to improve brain function in healthy people, said Stefan Borgward, chair and director of the department of psychiatry and psychotherapy at the University of Lubeck, Germany.In a 2014 study, he gave one or two cups of green tea to 12 healthy volunteers and imaged their brains to analyze changes in connectivity inside certain brain regions.“We noticed an increased connectivity in regions of the brain associated with working memory,” he said via email.And a 2017 review of more than 100 studies he coauthored found that green tea can impact the brain in three ways: It can influence psychopathological state such as reducing anxiety; cognition by benefiting memory and attention; and brain function, specifically memory.That review concluded that "it would be desirable" for more Westerners to consume at least 100 milliliters(3.3 fluid ounces) of green tea each day “to protect neurocognitive function.”However, Borgward, cautioned that the effects aren't large, and the evidence is mainly provided by small-scale studies.4. How does the author introduce the tendency of drinking in the U.S.?A. By showing examples.B. By explaining reasons.C. By making a comparison.D. By checking existing facts.5. What is paragraph 3 mainly about?A. Scientists are looking into why tea makes people relaxed and refreshed.B. The context in which the drink is consumed is very important.C. People's relaxation is the direct biological outcome of the ingredients in tea.D. Preparing tea, choosing a cup and sitting down for a brief rest is amazing.6. What can we conclude from Stefan's research?A. Tea is a cure for a neurocognitive disease.B. Green tea is particularly beneficial to our memory.C. Drinking tea every day can prevent us from getting ill.D. Westerners drink less than 100 milliliters of green tea.7. What is the researcher'sattitude towards the finding?A. SupportiveB. Doubtful.C. Unclear.D. Objective.CEvery day, millions of shoppers hit the stores in full force, searching wildly for the perfect gift.Aside from purchasing holiday gifts, most people regularly buy presents for other occasions throughout the year, including weddings, birthdays, anniversaries, and graduations. This frequent experience of gift-giving cancause uncertain feelings in gift-givers. Many enjoy the opportunity to buy presents because gift-giving offers a powerful means to build stronger bonds, while many worry that their purchases will disappoint rather than delight the intended recipients (接受者).Anthropologists describe gift-giving as a positive social process, serving various political, religious, and psychological functions. Economists, however, offer a less favorable view. According to Waldfogel, gift-giving represents an objective wasteof resources. People buy gifts that recipients would not choose to buy on their own, or at least not spend as much money to purchase (a phenomenon referred to as‘‘the deadweight loss ofChristmas”).What is surprising is that gift-givers have much experience acting as both gift-givers and gift-recipients, but nevertheless tend to overspend each time they set out to purchase a meaningful gift. In the present research, we propose a unique psychological explanation for this overspending problem — gift-givers link how much they spend with how much recipients will appreciate the gift. Though it seems natural to gift-givers, such an assumption may be unfounded. Indeed, we propose that gift-recipients will be less likely to base their feelings of appreciation on the value of a gift than givers assume.Why do gift-givers assume that gift price is closely linked to gift-recipients’ feelings of appreciation? Perhaps givers believe that more expensive gifts communicate a stronger sense ofthoughtfulness and consideration. According to Camerer and others, gift-giving represents a symbolic ritual (习俗), by which gift-givers attempt to signal their positive attitudes towards the recipient and their willingness to invest resources in a futurerelationship. In this sense, gift-givers may be motivated to spend more money on a gift in order to send a “stronger signal”. As for gift-recipients, they may not interpret smaller and larger gifts as representing smaller and larger signals of thoughtfulness and consideration.The idea of gift-givers and gift-recipients being unable to account for the other party’s viewpoint seems confusing because people slip in and out of these roles every day. Yet, despite the experience as both givers and receivers, people often struggle to apply information gained from one role in another. In theoretical terms, people fail to use information about their own preferences and experiences to produce more efficient outcomes in their exchange relations. In practical terms, people spend hundreds of dollars each year on gifts, but somehow never learn to estimate their gift expense according to personal insight.8. The author uses “the deadweight loss of Christmas” in Paragraph 2 to express ________.A. gift-givers don’t spend much money during holidaysB. gift-givers don’t ask recipients what gifts they preferC. gift-givers buy improper and expensive giftsD. gift-givers have difficulty in choosing gifts9. According to the passage, people buy gifts to ________.A. receive gifts in returnB. enjoy the feeling of shoppingC. help recipients to save moneyD. better relationships with recipients10. What can we learn from the passage?A. People’s high living standards require expensive gifts.B. Gift-givers buy gifts based on their experiences as recipients.C. Anthropologists think gift-giving meets different human needs.D. Recipients judge the depth of friendship according to the gift price.11. Why did the author write this article?A. To criticize people’s gift-buying habits.B. To analyze people’s gift-giving behaviors.C. To offer advice on how to improve relationships.D. To remind people not to overlook others’ preferences.DWe touch our faces all the time, and it had never seemed to be a big problem—until COVID-19 arrived. Touching our faces—the "T-zone" of our eyes, nose and mouth in particular—can mean giving ourselves the deadly virus.This is why organizations like the Centers for Disease Control and Prevention (CDC) have suggested that we avoid touching our faces. "Just stop this simple behavior," William Sawyer, founder of Henry the Hand, a nonprofit organization that promotes hand hygiene (卫生), told The Washington Post. "It's the one behavior that would be better than any vaccine (疫苗) ever created."Yet, stopping this "simple" behavior might be harder than you think because it's already hardwired (固定存在于) into our system.Some face touchingis an automatic reflex (反射) —like when there is an itch (痒) on your nose, you'll scratch (挠) it without thinking. According to CNBC, a 2014 study found that touching your face also helps to reduce stress and regulate emotions. For example, you're more likely to do it when you feel awkward or embarrassed. According to Dacher Keltner, a psychologist at the University of California Berkeley, US, this action may also come with a social function: When you are talking to someone and want to change the subject, for example, touching your face is like "the curtains on a stage, closing up one act of the social drama, ushering (引导) in the next," Keltner told the BBC.Moreover, face-touching in almost all of these occasions is subconscious, which means it's very hard to change "because you don't even know you're doing it", said Sawyer. But you're not alone. In a 2015 study, wherea group of medical students were filmed in class, it was found that they touched their faces an average of 23 timesan hour—with 44 percent of the touches being in the "T-zones". That was particularly surprising since medical students were supposed to know better.Since it's so hard to shake the habit, maybe the easiest way is to wash our hands more often. This way, we can be sure that our hands are free from the novel coronavirus.12. What do the first two paragraphs talk about?A. The best way to fight COVID-19B. How organizations are fighting COVID-19.C. Typical hand hygiene problems in the fight against COVID-19.D. The necessity to avoid touching our faces to fight COVID-19.13. Why is it hard for people to stop touching their faces?A. It makes people feel more confident.B. Many are unaware of this behavior's risks.C. They usually do it automatically and subconsciouslyD. Many think the action helps them express their emotions.14. Which of the following is a social function of touching faces, according to the text?A. Using it as a sign to change the topicB. Bringing a conversation to an end.C. Showing an interest in the ongoing subject.D. Making others feel relaxed while talking.15. What is the author's purpose in mentioning a 2015 study on a group of medical students?A. To give tips on how to stop touching faces.B. To prove that it is common for people to touch their faces.C. To show it is impossible to shake the habit of touching your face.D. To show how hygiene awareness helps people avoid touching their faces.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。

林子深处张炜芦青河口那围遭儿树多。
大片大片的树林子，里面横一条小路，竖一条小路，非把人走迷了不可。
因此河边的各家老人都常常告诫自己的孩子——没事儿，千万不要往林子深处走！可二兰子倒蛮不在乎，她常钻到林子深处割牛草。
家里养个老牛，肚子比碾砣还大，地上放捆嫩草叶儿，它伸出舌头抿几下就光了。
大弟弟忙着复习考大学，小弟弟要进重点班，惟独她不被看重，忙里忙外，出工前还得去割一大早的牛草。
割就割吧，她没上几天学，管“太”念“大”，常常忽略中间那“一点儿”，还不得割牛草吗？可近处的青草全被人割光了，不进林子深处行吗？好在二兰子还从没有迷过路。
早晨，还是很早的时候就进林子了。
一路上，也不知踢散了多少露珠儿。
太阳升起来了，光芒透过树隙，像一把长长的剑。
小鸟儿就像不闲嘴儿的小姑娘，吵死人了！还是老野鸡性子缓——多长的时间才叫一声“喀喀嗒”呀！二兰子总是这样：不管心里多么不痛快，一进了这林子就变得高兴了。
大树林子绿蒙蒙的，多宽敞啊，她很想扬起脖儿喊一句，听听自己在这树林子里的声音。
她知道，树林子能把声音传出老远、拖得老长，树林子真好哩！可她憋住了，她要赶去割草呢。
她只瞅着脚下的草叶儿，急急地走。
她走着，地上的草叶儿嫩极了，一簇一簇，顶着露珠儿，闪着亮儿，二兰子还不割吗？不割！不割！她继续往前走着……地上的草叶儿墨绿墨绿，又深又密，简直连成片儿了，二兰子还不割吗？不割！不割！她还是往前走……又穿过几排杨树，跨进了杂树林子。
看吧，这里的草叶儿才叫好呢！青青一片，崭新崭新的，叶片儿宽板板，长溜溜，就像初夏的麦苗儿。
那草窠里面还有花哩，红一朵，黄一朵，二兰子先拣一朵大的插在头上，然后才解了绳儿，举起手里那把雪亮亮的镰刀……小鸟儿在头顶“喳喳”地叫了几声，清甜的空气直往鼻孔里扑，二兰子高兴极了！她盯着那镰刀刃儿，镰刀刃儿锃亮锃亮，反射着阳光，耀得她眯起了眼。

2020-2021学年泰顺县育才高级中学高三语文二模试题及答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字,完成下面小题。
材料一:传统“中国式”家庭包括三代人:祖父母、父母和子女。
在这种家庭单位里,家长把后代看成自己的私有物,孩子也把家看成最坚强的后盾。
中国人家族血缘关系比较紧密,相对西方来说亲情更浓厚。
长辈对自己的家庭和子女很重视,相应地,孩子也更愿意照顾和陪伴他们的父母和祖父母。
(摘编自《中国人的家庭观念》)材料二:传统中国家庭中个人与家庭是荣辱与共的。
古代刑法中有“连坐” 或“株连”制度,一人犯事，家属亲友甚至上下好几代都跟着遭殃。
社会将每个家长权下的集体看成一个整体,他们都是家长的附属,家长对他们有管理处分的权力,也有承担责任的义务。
婚姻不是男女之间的私事,而是关系整个家庭或家族兴衰的大事。
所以历来讲究父母之命,媒妁之言,讲求门当户对。
中国人讲究家和万事兴,当自己的利益与家庭的利益发生冲突时, 要牺牲个人利益保全家庭利益。
这些规矩维持了一个家庭内部的秩序, 而如果每个家庭的男子都能“齐家”,整个国家也就安定团结。
进入现代社会后,尤其是随着商品经济的发展,有了更多样的家庭组合方式,比如三口之家可以和父母辈住在一起,也可以自立门户。
单身青年可以和父母住在一起,也可以到别的地方独立生活。
个人价值观也在发生变化,特别是西方的自由主义和个人主义在现代社会得到广泛接受和认可。
西方人重视自我价值、渴望独立和自由, 认为人是完全独立的个体,不依附于家庭和父母,血缘对家庭关系的纽带作用不是特别大。
女性受教育程度的提高和经济上的独立，对传统家庭观念也构成了冲击。
在封建社会，女性经济上附属于家庭，不可能独立生活,而现在, 她们受到的教育足以使自己拥有稳定的职业和收入,不需要再依附于男人或者家庭。
再加上西方女权主义思想影响,越来越多的女性选择独身。
(摘编自《传统家庭观念在瓦解?》)材料三:家庭核心化、小型化在很大程度上满足了人们对相对自由生活方式的追求,当然多数亲代和子女分爨生活后仍保持着较密切的日常联系。

China Satellite Navigation OfficeBChildren's average daily time spent watching television or using mobile device increased from 53 minutes at age 12 months to more than 150 minutes at 3 years, according toan analysis by researchers at the National Institutes of Health (NIH). By age 8, children were more likely to log the highest amount of screen time if they had been in home-based children or were born to first-time mothers.“Our results indicate that screen habits begin early, ”said Edwina Yeung, an investigator in National Institute of Child Health and Human Development (NICHD).“This finding suggests that interventions(干涉) to reduce screen time could have a better chance of success if introduced early.”In the research, mothers of 4, 000 children responded to questions on their kids' media habits when they were 12, 18, 24, 30, and 36 months of age.TheAmericanAcademyof Pediatrics recommends avoiding digital media exposure for children under 18 months of age, introducing children 18 to 24 months of age to screen media slowly, and limiting screen time to an hour a day for children from 2 to 5 years of age. In the current study, researchers found that 87% of the children had screen time exceeding (超过) these recommendations. However, while screen time increased throughout toddlerhood, by age 7 and 8, screen time fell to under 1.5 hours per day. The researchers believe this decrease relates to time consumed by school-related activities.The study authors classified the children into two groups based on how much their average daily screen time increased from age 1 to age 3. The first group, 73% of the total had the lowest increase, from an average of nearly 51 minutes a day to nearly an hour and 47 minutes a day. The second group, 27% of the total, had the highestincrease, from nearly 37 minutes of screen time a day to about 4 hours a day. Higher levels of parental education were associated with lower odds of inclusion in the second group.4. Who use mobile device longest according to the NIH's analysis?A. 10-year-old born to first-time mothers.B. 3-year-old children in low income families.C. 8-year-old children in home-based childcare.D. 1-year-old children with parents poorly educated.5. What does the research suggest according to Edwina?A. Parents should stop their children using media.B. Parents should limit the use of digital media themselves.C. Parents should reduce their children's screen time earlier.D. Parents should avoid their children using digital media at infancy (婴儿期).6. Why does children's screen time fall when they age 7 and 8?A. They are studying at school.B. They can control themselves.C. They are tired of using them.D. They are forbidden to use them.7. Which of the following may be the best title?A. Keep Away from MediaB. Screen Habits Begin EarlyC. Urgency of Parental EducationD. Harm of Home-based ChildcareCPaper is one of our oldest, simplest and most important inventions. But it also presents a danger to the world in two important ways. First, the making of paper requires the loss of many millions of trees each year. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot stand such a high rate of forest loss. The second great problem with paper is what happens once it is no longer useful. A large amount of wastepaper ends up in landfills, where it can produce harmful gases and finally contribute to global climate change.One simple solution can greatly reduce both of these problems: paper recycling. Instead of cutting down trees, recycle existing paper to feed the paper-making process.Paper is mainly made from cellulose (纤维素)，which can be used repeatedly in papermaking. Unfortunately, it also means that paper waste takes a surprisingly long time to break down in landfills. So far, trees are the only source(来源) of cellulose that can fill the great demand for paper products. Therefore, recycling paper is simplyone of the best ways to save trees. Thanks to advances in processing, recycled paper need not be the dark-color1 edstuff many of us are familiar with. It now can offer the same print performance as non-recycled paper.Effective recycling requires a continuous effort from everyone at all levels of society. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be developed.The need is real. The massive loss of trees affects everybody on earth. Everyone should do their part to recycle paper and encourage government and industry to do the same. The world will be a better place for it!8. What can we infer from the text?A. The use of recycled paper will double in 40 years.B. Recycling paper helps relieve global climate change.C. Wastepaper can easily break down in landfills.D. There are not enough landfills for wastepaper.9. What makes recycled paper more acceptable?A. The great demand of trees.B. The low processing cost.C. Its dark-color1 ed feature.D. Its improved print performance.10. What does the author propose?A. Punishing the act of cutting trees.B. Recycling paper.C. Improving recycling system.D. Promoting paper industry.11. How is the text mainly developed?A. By analyzing causes and effects.B. By offering research plans and data.C. By discussing problems and solutions.D. By comparing strengths and weaknesses.DSmart speakers have proven to be handy devices in hospitals, allowing patients to control independently . And now, researchers from theUniversityofWashingtonhave developed an artificial intelligence system that enables these devices to monitor heartbeats.Using technology to remotely monitor heart rates isn't new. These days most smartwatches and fitness trackers are capable of it. The good thing here is that researchers have figured out a way to use the microphones in smart speakers to do it without requiring physical contact.In a study published inCommunications Biology, the researchers had the smart speakers send out signals that couldn't be heard which were then reflected off a person's body. They then analyzed these signals to identify smallchest wall motions related to heartbeats, as well as separate those signals from surrounding noise and breathing.For this particular proof — of — concept setup, the researchers tested this smart speaker on 26 healthy participants and 24 hospitalized patients with various heart conditions, including atrial fibrillation（心房颤动）and heart failure. In both cases, the smart speaker was within 28 -30 milliseconds of an ECG（心电图）,the gold standard used in hospitals to discover arrhythmia（心律不齐）.Like smartwatches with advanced heart features, using smart speakers in this way opens up the possibility for passive, remote heart monitoring. ECGs, while highly accurate, require a visit to the doctor and several electrodes （电极）to be placed on the body. They,re not capable of continuous monitoring so you're limited to what it picks up at that exact moment in time ——one reason why heart arrhythmia can be so hard to discover.Smartwatches are capable of passive, remote, continuous monitoring, but they require you to wear the device at all times to be effective. It's not something that's comfortable for everyone, especially when it comes to sleep and for those with highly sensitive skin. Another issue is that these advanced smartwatches are expensive, while smart speakers are much cheaper.“If you have a device like this, you can monitor a patient on an extended basis and then develop corresponding care plans that satisfy the patient' s needs,“ said Dr. Arun Sridhar, co — senior author on the study. "And the beauty of using this kind of devices is that they are already in people's homes.”12. What does the author focus on in Paragraph 3?A. How the smart speaker works.B. Why the smart speaker is useful.C. The advantages of smart speakers.D. The importance of the study.13. Why is heart arrhythmia difficult to find?A. ECGs are not highly accurate.B. ECGs can't monitor continuously.C. Doctors know little about heart arrhythmia.D. An ECG test is hard to operate and expensive.14. Which statement best explains the characteristics of smartwatches?A. They are comfortable to wear.B. They are friendly to sensitive skin.C. They are effective and cheap.D. They are able to monitor remotely.15. What can we infer from the last paragraph?A. We need to invent more smart devices.B. Care plans are vital to patients with heart failure.C. Smart speakers could be contactless heart monitors.D. Different devices are needed to meet patients,demands.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 extremelyexpensive. 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 protectionCWolves have a certain undeserved reputation: fierce, dangerous, good forhunting down deer and farmers’ livestock. 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 tothreats, 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.8. 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 wolves9. Which of the following flow chart best demonstrates the relationship between the wolves?A. B.C. D.10. 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.11. 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 wolvesDHumans are the only creature that gets around by standing up and putting one foot in front of the other. Our ability to walk upright has allowed humankind to travel great distances and survive changing climates, environments and landscapes.Countless scientific studies have found that walking is really good for us and this simple act can provide a number of healthimplications, which help people live longer. In fact, a walking routine, if done properly, might be the only exercise people need.How much walking should one aim for? You’ve likely heard we need 10,000 steps a day. That’s about 5 miles. But contrary to popular belief, this recommendation doesn’t come from science. Instead, itis from a 1960s advertising campaign to promote a pedometer (计步器) in Japan. Perhaps because it’s a round number and easy to remember, it stuck.Since the 1960s, researchers have studied the 10,000-steps-a-day standard and have turned up mixed results. Although 10,000 steps is certainly a healthy and worthwhile goal, it’s not fit for all.For instance, a recent Harvard University study involving more than 16,000 senior women found that those who got at least 4,400 steps a day greatly reduced their risk of dying early when compared with less active women. The study also noted that these benefits continued up to 7,500 steps. This 7,500 mark isn’t surprising: It’s similar to common public health recommendations, such as the Centers for Disease Control and Prevention’s recommendation of 150 minutes of moderate (适度的) physical activity a week for adults.12. What does the underlined word “implications” in Paragraph 2 refer to?A. BenefitsB. Problems.C. Habits.D. Manners.13. Where does the 10,000-steps-a-day standard come from?A. A Harvard University study.B. Science research on health.C. A pedometer advertisement.D. Public health recommendation.14. What can we know from the last paragraph?A. 7,500-steps-a-day standard is the best choice for all.B. More than 16,000 old people were involved in the study.C. Those who walk at least 4,400 steps a day won’t die early.D. 150-minute moderate exercise a week for adults is advised.15. What does the author mainly want to tell readers?A. The more you walk a day, the healthier you will be.B. We can benefit from continuous and proper walking.C. Walking upright helps humankind to explore the world.D. Advertisements can always tell us some scientific suggestions .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。
2020届泰顺县育才高级中学高三英语二模试卷及参考答案
2020届泰顺县育才高级中学高三英语二模试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AChildren under the age of 18 will be allowed up to three hours per week to play video games, according to a notice issued by China's National Press and Publication Administration. Online game companies are required to provide services to minors — from8 to 9 p. m. on Fridays, Saturdays, Sundays and legal holidays — as a way to safeguard their physical and mental health. Children are playing more and more online games these days. Is it time to limit their online gaming time? What role do parents have? Readers share their opinions.RizlaredOnline games are addictive, but if children are taught how to manage in a sensible and responsible manner then it is no longer a threat(威胁).To achieve this, parents need to set examples for not being glued to their phones. Teaching is and always will be the best solution to such problems.AndrewGood policy. By limiting time spent on online games, kids can spend time doing more useful things to develop their potential. They can go outside and run, jump and swim instead of sitting on a couch at home and playing with a smart phone.AdamIt is often seen that parents argue with children over cellphones. Most parents can hardly set and enforce the time limit for its daily usage. Some forcibly take away their cellphones, but it will ruin trust and relationship. Even worse, it will make their kids hate them.PinkExcessive(过度的）gaming is purely a waste of time and energy for minors and has a negative effect on both physical and mental health. The gaming industry should not put profit- flaking interests as its priority (优先事项) . They should act in a socially responsible way toprovide an environment for children to ensure their well-being and development.LaurenThere would be a loophole(漏洞). Children could use their parents’ or other adults’ IDs to avoid real-name registration, thus making it impossible to put this policy in effect. Parents ly need to strengthen guidance andsupervision to keep their children from gaming addiction.1. What should kids do according to Andrew?A. Play online games.B. Play with a smart phone.C. Study all the time.D. Go in for outside activities.2. What does Pink advise the gaming industry to do?A. Pay attention to its profit.B. Focus on kids’ health.C. Be responsible for kids’ surroundings.D. Persuade kids lo play more games.3. What role do parents have according to the passage?A. They keep hold of their phones.B. They set examples for their kids.C. They limit their kids’ time.D. They blame kids for addiction.BAccording 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 of online 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’relistening 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.4. 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.5. 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.6. The underlined word “ritualistic” in Para.4 means something ______.A. Overlooked by society.B. Updated very frequently.C. Performed as part of a ceremony.D. Kept for a long time without changing.7. How does the writer feel about the future development of music medium?A. Traditional records will get underway.B. The analogue experiences may matter more.C. Vinyl sales will boom with technological advance.D. There should be a good mix of old and new.CMy 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 whichis 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.8. What did the writer think of the server's words?A. Impressive.B. Ridiculous.C. Amusing.D. Logical.9. 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.10. Which of the following best describes the writer's restaurant work?A. Boring.B. Relaxing.C. Worthwhile.D. Unchallenging.11. 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.DWhile the arts can' t stop the COVID-19 virus or the social unrest we see in the world today, they can give us insight into the choices we make when moving through crises and chaos. The arts invite everyone to think in new ways.We often experience works of art as something that's pleasing to our senses without a full understanding of the creative effort. Great art often shows us contradictions and crises, and we can learn a great deal from their resolutions(解决). Through our understanding of art, we can gain a deeper understanding of how we might overcome our own challenges. In understanding extremes of contrast, we can see the beauty in art with themes that are not simply pleasing for their magnificent features or qualities.Beethoven offers a wonderful example of moving artfully through crises and chaos. He composed his Symphony No. 9 as his hearing loss became more and more pronounced. The opening of the symphony seems to come out of nowhere, from near silence in the opening to a full expression of what many consider to be the joy of freedom and universal brotherhood with Schiller’s Ode to joy（欢乐颂). Beethoven appears to have created a work of art that not only freed him from his personal struggles, but one that also speaks to the joy of living together in peace and harmony.Have a dialogue between the two opposing parts and you will find that they always start out fighting each other until we come to an appreciation of difference—a oneness of the two opposingforces.The arts offer many lessons that can help us gain the knowledge we need to move more confidently in today’ s competitive and uncertain environment. An openness to arts-based solutions will give you more control over your future.12. What value does art have beyond pleasing people's senses?A. It brings people inner peace.B. It contributes to problem-solving.C. It reduces the possibility of crises.D. It deepens understanding of music.13. What can we learn about Beethoven's Symphony No. 9?A. It celebrates freedom and unity.B. It aims to show crises and chaos.C. It opens with Schiller's Ode to Joy.D. It is unfinished due to his hearing loss.14. What is the author's suggestion on dealing with conflicting forces?A. Leaving things as they are.B. Making a choice between them.C. Separating them from each other.D. Engaging them in a conversation.15. Which of the following can be the best title for the text?A. How COVID-19 changes artB. Essentials of Symphony No. 9C. Moving artfully through crisesD. Joy in the eyes of Beethoven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。

2020-2021学年泰顺县育才高级中学高三英语二模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AIn his 402nd anniversary year, Shakespeare is still rightly celebrated as a great language master and writer. But he was not the only great master of play writing to die in 1616, and he is certainly not the only writer to have left a lasting influence on theater.While less known worldwide, Tang Xianzu is considered one of Chinas greatest playwrights and is highly spoken of in that country of ancient literary and dramatic traditions.Tang was born in 1550 inLinchuan,Jiangxiprovince. Unlike Shakespeare's large body of plays,poems and sonnets (十四行诗), Tang wrote only four major plays: The Purple Hairpin, Peony Pavilion (《牡丹亭》), A Dream under the Southern bough, and Dream of Handan. The latter three were constructed around a dream narrative, a way through which Tang unlocked the emotional dimension of human desires and ambitions and explored human nature beyond the social and political limits of that time.Similar to Shakespeare, Tang's success rode the wave of a renaissance (复兴) in theater as an artistic practice. As in Shakespeare'sEngland, Tang's works became hugely popular inChinatoo. During Tang'sChina, his plays were enjoyed performed, and changed. Kunqu Opera, a form of musical drama, spread from southernChinato the whole nation and became a symbol of Chinese culture. Combining northern tune and southern music, kunqu Opera was known for its poetic language, music, dance movements and gestures. Tang's works benefited greatly from the popularity of kunqu Opera, and his plays are considered classics of kunqu Opera.While Tang and Shakespeare lived in a world away from each other, there are many things they share in common, such e humanity of their drama, their heroic figures, their love for poetic language, a lasting popularity and the anniversary during which we still celebrate them.1. Why is Shakespeare mentioned in the first paragraph?A. To describe Shakespeare's anniversary.B. To introduce the existence of Tang Xianzu.C. To explain the importance of Shakespeare.D. To suggest the less popularity of Tang Xianzu.2. What's possibly one of the main theme of Tang's works?A. Social reality.B. Female dreams.C. Human emotions.D. Political environment.3. What does the author mainly tell us in Paragraph 4?A. The influence of Kunqu Opera on Tang's works.B. Tang's success in copying Shakespeare's styles.C. The way Kunqu Opera became a symbol of Chinese culture.D. Tang's popularity for his poetic language and music.BHappiness is not a warm phone, according to anew study exploring the link between young life satisfaction and screen time. The study was led by professor of psychology Jean M. Twenge at San Diego State University (SDSU).To research this link, Twenge, along with colleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University of Georgia, dealt with data from the Monitoring the Future (MtF) study, a nationally representative survey of more than a million U. S. 8th-, 10th-, and 12th-graders. The survey asked students questions about how often they spent time on their Phones, tablets and computers, as well as questions about their face-to-face social interactions and their overall happiness.On average found that teens who spent more time in front of screen devices — playing computer games, using social media, texting and video chatting — were less happy than those who invested more time in non-screen activities like sports, reading newspapers and magazines, and face-to-face social interactions."The key to digital media use and happiness is limited use," Twenge said. "Aim to spend no more than two hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face and exercising — two activities reliably linked to greater happiness."Looking at historical trends from the same age groups since the 1990s, it's easy to find that the increase of screen devices over time happened at the same time as a general drop-off in reported happiness inU. S.teens. Specifically, young peopled life satisfaction and happiness declined sharply after 2012. That's the year when the percentage of Americans who owned a smartphone rose above 50 percent. By far the largest change in teens' lives between 2012 and 2016 was the increase in the amount of time they spent on digital media, and the following decline in in-person social activities and sleep.4. Which method did Twenge's team use for the study?A. Calculating students' happiness.B. Asking students certain questions.C. Analyzing data from a survey.D. Doing experiments on screen time.5. How does the author develop the finding of the study in paragraph 3?A. By making a comparison.B. By giving an example.C. By making an argument.D. By introducing a concept.6. What is the purpose of the last paragraph?A. To draw a conclusion from the study.B. To offer some advice to the readers.C. To prove social activities' importance.D. To support the researchers' finding.7. Which of the following can be the best title for the text?A. Quitting Phones Equals HappinessB. Screen Time Should Be BannedC. Teens' Lives Have Changed SharplyD. Screen-addicted Teens Are UnhappierCA dog spentthe lastfour years of his life waitingat a crossroad in the Thai city ofKhon Kaenas if waiting for someone. People originally thought the dog had been abandoned, but then realized that he looked healthy, so people asked around about him. It turned out that the dog had indeed been spending most of his time around that crossroad, but a woman had been coming round regularly to bring him food and water.One day, while photographing the dog everyone called Leo, a reporter met the woman who had been taking care of him. She had come to drop off some food. After learning the story about the dog and the woman, the reporter decided to share the story on social media. The post soonwent viraland the photos of Leo got shared hundreds of times. And the photos reached the eyes of Leo’s former old owner.Nang Noi Sittisarn, a 64-year-old woman fromThailand’sRoiEtProvince, almost had a heart attack when her daughter showed her a photo of the beloved dog named BonBon she had lost during a car trip. When she learned that he had been waiting for her in the same spot for the last four years，her heart melted(融化).Auntie Noi told her daughter to drive her to where the dog was waiting. When she got there and called his name. BonBon，the poor dog started wiggling(扭动)his tailand came to her，but when she tried to take him home with her, he was unwilling to follow. She didn’ t want to force the dog to come with her so she agreed to leave him with his new master. However, she and her daughter will come to visit him regularly.8.Why did the dog look healthy after separation from his former owner?A. He walked around the crossroad constantly.B. He was kept at a woman’s home all the time.C. A local reporter brought him food and water.D. A woman looked after him on a regular basis.9.

How did Nang Noi Sittisam feel about the dog's waiting for her?A. Shocked.B. Regretful.C. Touched.D. Proud.11. What can we mainly learn from the story about the dog?A. Unbelievable success is worth waiting for.B. We should adjust ourselves to environments.C. We need to learn to be faithful and thankful.D. No one knows the result until the last minuteDIf you ever find yourself trapped in the wilderness without food, you'llhave to figure out how to feed yourself. Many plants in the wild areedible, but many are also poisonous. So it is necessary to learn how to determine whether the plants you find can be eaten safely.Avoid using this method without careful planning. Some plants can be deadly, and even if you follow these guidelines perfectly, there is always a chance that a plant will make you seriously ill. Prepare yourself for wilderness outings by learning about the local plants, and carry a guidebook to help you identify plants. Even if you are unprepared and cannot find food you know to be safe, remember that, depending on your activity level, the human body can go for days without food, and you’re better off being hungry than being poisoned.Testing the plant in your mouth is dangerous, so go forward very slowly and carefully. First, hold a small portion of the prepared plant part against your lip for 3 minutes. Do not put the plant in your mouth. If you noticeany burning, tingling (刺痛), or other reactions, discontinue testing. Second, place another small portion of the plant part on your tongue. Hold the plant on your tongue without chewing for 15 minutes. Discontinue testing if you notice any reaction. Third, chew the plant and holdit in your mouth for 15 minutes. Chew the plant well, and do not swallow. Discontinue testing if you notice any reaction. Fourth, swallow the small portion of the plant. Wait 8 hours. Do not eat or drink anything during this period except purified water. If you feel sick, immediately throw up what you eat and drink plenty of water. If activated charcoal (活性炭) is available, take that with the water.12. What’s the meaning of the underlined world “edible” in paragraph 1?A. Suitable for using as food.B. Widely spread.C. Existing in large quantities.D. Not widely known.13. What can we know from paragraph 2?A. Planning is unnecessary when using the method.B. Not all plants in the wild can serve as food generally.C. Suffering hunger can be more dangerous than testing plants.D. Following the method perfectly can ensure safety.14. Which is the correct order of testing plants in the mouth?① wait and see ② chew it in the mouth③ put it on the tongue④ put it against lips ⑤ swallow itA. ③④②①⑤B. ④③②①⑤C. ③④②⑤①D.④③②⑤①15.

2020届温州市泰顺县育才高级中学高三英语二模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AThe history ofpop art begins with abstract art. Pop art emerged from the foundation of abstract art in the 1950s, first gaining recognition in Great Britain, then establishing itself in the United States in the 1960s.In the 1930s and 1940s, abstract art was greatly popular, but people began to hate this art form. Most abstract art produced in this era could be found in art galleries or the homes of the elite(名流), not in the homes of everyday people. Pop art sprung onto the scene as the people's art.Some art critics say pop art is a rebellion against abstract art; others say it is an extension of abstract art. You can see elements of abstract art in many pop art prints, especially those that consist of a collage（拼贴画）of images. However, some pop art pieces have nothing to do with abstract art, looking more like a photo of a popular consumer item, which impressed people deeply.Richard Hamilton and Eduardo Paolozzi were two of the first contemporary pop art pioneers recognised in Great Britain. They were a part of the Independent Group, an organised group of British artists who wanted to challenge ruling modernist approaches to culture. They recognised the value of modern advertising and comic book images. They used these popular images in art as a social commentary, often building irony and humour into their artworks, thus creating a new form of art. These pieces were mass-produced and sold at affordable prices.When pop art took off in the United States, it expanded to include a celebration of kitsch and the common images found in movies and television. Andy Wharhol is perhaps the most famous American pop art artist, known for his prints of the actress Marilyn Monroe, the singer Elvis Presley and of Campbell's soup cans. Andy Wharhol was inspired by images from advertisements and common consumer items. He also made a series of paintings which showed images of car accidents.1. Why did people dislike abstract art?A. People found it hard to understand.B. Ordinary people couldn't afford it.C. People disliked enjoying it in galleries.D. It wasn't based on everyday life.2. What impression do pop art works leave on people?A. They are a rebellion against abstract art.B. They have many elements of abstract art.C. They are created so real.D. They are products of advertisers.3. The Independent Group was set up to ________.A. introduce a new art form to the worldB. develop modern advertising furtherC. create new comic book imagesD. make British culture better knownBDo you ever listen to the songs that your parents like? Chances are that you don’t. You probably think the music that they like is old and boring and that the songs on your playlist are muchcooler. But scientists found that people’s music taste changes as time goes by. So it is likely that your own musical preferences will follow a similar path to your parents’, whether you like it or not.We used to think that culture and personality (个性) are the only reasons for different music choices. But researchers at the University of Cambridge noticed that as people enter into different age groups, their social environment changes, and so does their music taste. There are some musical periods that people go through in their life.The first period comes in the teenage years, during which people like strong music such as punk and rock, because teenagers tend to be aggressive or want to be independent.But as people move into early adulthood, their lifestyles change they want to build close relationships with others. As a result, they become fonder of contemporary music, such as pop and R&.B, which is usually uplifting and danceable.When middle age comes, most people have settled down. During this period, people prefer music, such as jazz and classical, as well as music like country, folk and blues.As for old people, they prefer old songs in their childhoods. They generally listen to relaxing music, such as country music and jazz music. But you must be questioning. “Aren’t there old people who are still interested in or even crazy about rock music?” Of course there are. But their reasons for listening to rock music may have changed. At that age people may listen to remind themselves of their youth.4. What do young people usually think of the songs their parents enjoy?A. They are actually less cool.B. They are worth listening to.C. They are especially serious.D. They are hard to understand.5. How many musical periods are there that people go through in their life?A. Two.B. Three.C. Four.D. Five.6. People who want to make friends mostly prefer ________.A. jazz musicB. country musicC. rock musicD. pop music7. What is the best title for the text?A. People Have Different Opinions on MusicB. People Listen to Music for the Same ReasonC. People’s Taste in Music Changes with TimeD. People’s Lifestyle Can Be Changed by MusicCA young female athlete in thePhilippinesrecently won many gold medals during a sports meet despite not having proper running shoes. Rhea Ballos, an 11-year-old student ofSalvationElementary Schoolin Balason,Iloilo, wasonly wearing bandages around her feet when she competed at the Iloilo Schools Sports Meet.Facebook user Valenzuela posted pictures of the girl with her feet wrapped in bandages bearing the famous Nike logo. Ballos even wrote the word “NIKE” on the sides of her “shoe” to complete the “Nike running shoes” look. The bandages were tightly wrapped around her feet, creating a thin protective layer against the track. While she was actually barefoot during the races, she was still able to defeat her competitors who all more proper footwear intended for running,According to the post, Ballos bagged the top awards in the 400-meter dash, the 800-meter run, and the 1500-meter run in the girls' categories in the inter school sporting event held in Iloilo, central Philippines.When pictures of her “Nike” footwear become popular, Flipinos on social media praised her. Many noted that instead of falling into self-pity, she was even able to make light of the situation by drawing the Nike logo on her “running shoes”. Some of the commenters of Valenzuela's post expressed how the girl deserved to be recognized by Nike and that the brand should actually give her a new pair of real Nike shoes. Others started getting in touch with the American sports brand, as well as local basketball specialty store Titan 22.It did not take long for Titan co-founder and Alaska Aces head coach Jeffrey Cariaso to take notice of Ballos' outstanding achievement. Cariaso immediately made an effort to get in touch with the young track runner. The seven-time PBA champion has since talked to the student as well as her coaches in an apparent bid to help her out.8. Why did Ballos wear bandages around her feet to compete?A. She couldn't afford to buy shoes.B. She wished to be noticed by Nike.C. She wanted to draw public's attention.D. She thought it fashionable and unique.9. What's people's attitude to Ballos' story?A. Surprised.B. Confused.C. Favorable.D. Doubtful.10. What can we infer from the last paragraph?A. Ballos will be recognized by Nike.B. Ballos will be probably helped by Cariaso.C. Ballos is bound to win more champions.D. Ballos will become a great basketball player.11. Which of the following can best describe Ballos?A. Shy and lucky.B. Kind and brave.C. Clever and outstanding.D. Gifted and optimistic.DYou’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source（来源）of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part ofVon Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.In a piece from 2018, Von Wong wanted to illustrate（说明）a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped（倾倒）from a truck all atonce.Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.12. What are Von Wong’s artworks intended for?A. Beautifying the city he lives in.B. Introducing eco-friendly products.C. Drawing public attention to plastic waste.D. Reducing garbage on the beach.13. Why does the author discuss plastic straws in paragraph 3?A. To show the difficulty of their recycling.B. To explain why they are useful.C. To voice his views on modern art.D. To find a substitute for them.14. What effect would “Truckload of Plastic” have on viewers?A. Calming.B. Disturbing.C. Refreshing.D. Challenging.15. Which of the following can be the best title for the text?A. Artists’ Opinions on Plastic SafetyB. Media Interest in Contemporary ArtC. Responsibility Demanded of Big CompaniesD.

Basil reflects on some of her earliest memories of food and how it affected her upbringing and relationship with her parents. Now a parent herself, she centers food in her book's exploration of that change of identity.EastFrom Guardian columnist Meera Sodha comes a cookbook centered on vegetables. The book features recipes that cover a variety of Asian cuisines. Sodha showcases the diversity of vegetarian cooking with dishes like eggplant larb mushroom bao, Singapore noodles and so much more.I Cook in ColorA follow-up from her first cookbook My Two Souths, Asha Gomez focuses on the rainbow of vegetables to create desserts and cross-cultural dishes that associate cooking traditions of her mother's Keralite kitchen and Gomez's travel experiences.Time to EatIf you're a fan of The Great British Baking Show and Nadiya Hussain's Netflix series, you'll be just as excited for the American release of this book of time-saving tips for home cooks on a budget.

It was the largest wildfire in the state's recorded history, breaking the record previously set in 2018. After the fire, land managers must determine where to most efficiently plant new trees.A predictive mapping model called the Postfire Spatial Conifer Restoration Planning Tool recently described in Ecological Applications could inform these decisions, saving time and expense. The tool can “show where young trees are needed most, where the forest isn't going to come back on its own, where we need to intervene（干预）if we want to maintain forests," says lead author Joseph Stewart, an ecologist at the University of California, Davis.To develop the model, Stewart and his colleagues classified data collected from more than 1,200 study plots in 19 areas that burned between 2004 and 2012. They combined these data with information on rainfall, geography, climate, forest composition and bum severity.Theyalso included how many seeds sample conifer trees （针叶树）produced in 216locations over 18 years, assessing whether the trees release different numbers of seeds after a fire.The tool's potential benefits are significant, says Kimberley Davis, a conservation scientist at theUniversityofMontana, who was not involved in the study. Those managers will still have to make hard decisions, such as which species to plant in areas that may experience warmer and drier conditions resulting from climate change, but the model provides some research-based guidance to help the forests recover.4. What challenge do land managers face after the wildfire?A. Lack of wood supplies.B. Where to plant new trees best.C. How to save the burned trees.D. Loss of trees and wild animals.5. What's the main idea of paragraph 2?A. The function of the tool.B. The disadvantages of the tool.C. The improvement of the tool.D. The development of the tool.6. What does the underlined word "They" refer to?A. The study plots.B. The data.C. Stewart and his colleagues.D. The seeds.7. What isDavis' attitude towards the tool?A. Skeptical.B. Ambiguous.C. Tolerant.D. Optimistic.CWe asked four people who watched an online talk on technology and communication by Sherry Turkle for their opinions.Fred:The talk certainly gave me plenty of food for thought about how technology is changing our behaviour. People are constantly multitasking, whether it be emailing during meetings or texting in the checkout queue. It’s as if we can’t bear to miss out on what our online friends are up to, so we juggle the real and online world. My greatest concern is that we don’t give our brains a chance to switch off. It’sthese precious momentswhen we actually process information that helps us make important decisions.Jeremy:It was a fascinating talk and the speaker really hit the nail on the head with a couple of things. Take parental influence, for instance. How can we expect teenagers not to text while doing their homework when they witness their parents posting on social media while cooking the evening meal or waiting at a red light?Kath:So much of what the speaker said rang true. I honestly believe there’s a danger that the more connected we are, the more isolated we feel. I don’t think this is such an issue for my generation who’ve lived without technology for so long. We know how to be alone. But the under 20s are another kettle of fish. They’re so busy communicating that they never experience the feeling of solitude and run the risk of not learning how to enjoy their own company.Carl:I’m not sure to what extent I agree that people are more alone, but the way we communicate has certainly evolved. The speaker makes a good point about how we’re getting used to talking with machines like Siri or robots, which are totally lack of experience of human life. But despite such limitations, we seem to be expecting more from technology and less from each other.8. What does the underlined phrase “these precious moments” in paragraph 2 refer to?A. When our brains are free.B. When we emailing during meeting.C. When we texting in the checkout queue.D. When we juggle the real and online world.9. What suggestion may Jeremy give to the parents?A. Accompany their children when they are doing homework.B. Prevent their children using phone while doing homework.C. Set a good example for their children on using phone properly.D. Stop posting on social media in face of their children.10. What does Kath worry about the under 20s generation?A. They communicate more with others.B. They use more technology.C. It’s difficult for them to find companies.D. They don’t know how to be alone.11. What is Carl’s attitude towards the use of technology in communication?A. Favorable.B. Intolerant.C. Doubtful.D. Indifferent.DTen years ago, I set out to examine luck. I wanted to know why some people were always in the right place at the right time, while others consistently experienced ill fortune. I placed advertisements in national newspapers asking for people who felt consistently lucky or unlucky. Hundreds of extraordinary men and women volunteered for my research. Over the years I have interviewed them, monitored their lives and had them take part in various experiments.In one of the experiments, I gave both lucky and unlucky people a newspaper, asking them to look through it and tell me how many photographs were inside. I had secretly placed a large message halfway through the newspaper, saying, “Tell the experimenter you have seen this and you will win $50.” This message took up half of the page and was written in type that was more than two inches high. It was staring everyone in the face, but the unlucky people tended to miss it and the lucky people tended to spot it.Unlucky people are generally more nervous than lucky people, and this anxiety affects their ability to notice the unexpected. As a result, they miss opportunities because they are too focused on looking for something else.They go to gatherings concentrating on finding their perfect partners and miss opportunities to make good friends. They look through newspapers determined to find certain types of job advertisements and miss other types of jobs.Lucky people are more relaxed and open, and therefore see what is there rather than just what they are looking for. My research eventually showed that lucky people are skilled at noticing opportunities, make lucky decisions by listening to their intuition (直觉), are open to new experiences, and adopt a never-say-die attitude that transforms bad luck into good luck.12. What’s the purpose of the author’s research?A. To discover what luck means to people.B. To find lucky people and unlucky people.C. To distinguish between good luck and bad luck.D. To figure out why people are always lucky or unlucky.13. Why did the unlucky people miss the message in the experiment?A. There was too much information to be read in detail.B. They were too focused on looking for photographs.C. It took too much time to go through newspapers.D. The words were too small to be noticed.14. What leads to lucky people’s good fortune?A. Their ability to spot opportunities.B. Their ability to become relaxed.C. Their ability to communicate.D. Their ability to make friends.15. What’s the key message of the last paragraph?A. What lucky people are looking for.B. How lucky people generate good luck.C. What lucky people can do with opportunities.D How lucky people transform bad luck into good luck.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。

2021届温州市泰顺县育才高级中学高三英语二模试卷及参考答案
2021届温州市泰顺县育才高级中学高三英语二模试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ASome young people win attention because of their good looks or their singing ability. A much smaller number gain fame because they have done something important and worthwhile with their abilities. Rishab Jain is among the latter. In 2018, 13-year-oldRishab developed a way to use AI technology to help pancreatic(胰腺的) cancer patients and won the3MYoung Scientist Challenge, a nationwide middle-school science competition, and its $25,000 prize.In the last stage of the contest, Rishab competed againstnine other finalists at the 3M Innovation Center(创新中心) in St.Paul,Minnesota. Leading up to the big meet, each finalist had partnered with a scientist to further develop their inventions.Rishab explains what led him to create his invention. First,a family friend died of cancer. Then Rishab learned about how deadly pancreatic cancer is, and that its low survival rate is due to how difficult it is to treat. "I'm also into programming, so I was learning about AI technology. I decided to try to solve a real-world problem using it."His winnings have been put in further research and in his nonprofit Samyak Science Society, which helps poor children enter the STEM (science, technology, engineering and math) education. Rishab is also raising awareness about pancreatic cancer. These efforts make him quite different from teenagers of his age. Considering becoming a biomedical engineer or a doctor一or both, he has also put some money aside to further his own learning. Almost certainly the doors of higher education will open wide to him before he even knocks.That's an outstanding outlook for one so young. Rashib is committed to helping very sick people in need. He is also providing teenagers of his age with a much-needed model of what kinds of things youth can achieve.1. What can we learn about the 3M Young Scientist Challenge in 2018?A. It was intended to solve medical problems.B. It was a nationwide AI competition for teenagers.C. It offered the finalists an opportunity to work with scientists.D. It allowed the finalists to learn AI technology in the 3M center.2. How did Rishab win the 3M Young Scientist Challenge?A.He showed excellent programming ability.B. He figured out the survival rate of pancreatic cancer.C. He introduced poor children to STEM education.D. He applied AI technology to treating pancreatic cancer.3. Which of the following best describes Rishab?A. Talented and caring.B. Independent and humorous.C. Responsible and patient.D. Polite and inspiring.BTo Rehan Staton, his childhood was a life of privilege — loving parents, a supportive big brother and a pleasant, private school education. Everything changed when his mother left the country and his father lost his job.He had to sleep with a heavy jacket on when it was cold. He was always hungry. He said he couldn't concentrate at school and would sleep during class. He went from straight. As to near the bottom of his class. A teacher told him he needed special education, which made him hate school.Staton spent his high school years as an excellent athlete, raining to become a professional boxer. He had won a lot of martial arts competitions.But a tragedy struck him in his senior year when Staton suffered serious tendonitis (肌腱炎), in both shoulders. He couldn’t lift either arm for months. His dream of becoming a professional player failed. He struggled to apply to colleges but was refused byall of them.Staton’s body slowly recovered from martial arts and he got a job as a rubbish collector. Many co-workers couldn't help but ask him a simple question, “What are you doing here? You’re smart. You are too young to be here. Go to college.” It was the first time someone outside his family had spoken highly of his intelligence. It was the co-workers thatem enedhim to return to school.Several co-workers put Staton in touch with a professor atBowieStateUniversity. The professor was impressed with their conversation and persuaded the admissions board to change its former decision.Going to college forced Staton’s older brother, Reggie, to drop out. They both knew someone had to be working full time along with their dad. It was a decision Reggie made on his own.After receiving a 4.0, Staton succeeded in becoming a student at theUniversityofMaryland. But he still had a long way to go to attend Harvard Law eventually...4. What finally changed Rehan Staton’s happy childhood?A. His brother’s losing the job.B. His serious health problem.C. His father’s sudden death.D. His mother’s leaving the country.5. What does the underlined word “em ened” in the fourth paragraph mean?A. Force.B. Direct.C. Encourage.D. Accompany.6. Why did Staton’s elder brother have to drop out of school?A. He wanted his brother to study further.B. His father asked him to leave school.C. He had lost interest in most lessons.D. He had to go out to find his mother.7. What will the writer mainly talk about next?A. What Rehan Staton planned to do after entering Harvard.B. How Rehan Staton managed to be admitted to Harvard.C. Why Rehan Staton decided to choose to go to Harvard.D. When Rehan Staton would be successful in Harvard Law.CThe Rise of Voice TechnologyVoice technology has come a long way. Just a few years ago, it would have been unusable. But now, those who follow the technology know that it has got considerably better.Writing with your voice raises several interesting questions. How difficult is it actually? Human speech involves a lot more starting and stopping with errors and the need for repairing broken sentences than you may think. Even gifted speakers make mistakes. To turn the spoken word into reasonable writing requires lots of planning. You’ll need some kinds of notes or other organisers to make it work.Another question turning speech into writing raises is the style. How would writing make the change that people speak their writing rather than type? Chances are that it would come up with many more short sentences and more concrete language, which is good. It would probably also rely on prepared phrases a lot more often, which is not available when you are speaking quickly.To confirm this, a column was not written, but dictated (听写). It was composed from brief notes written down for structure only, and it was edited for length, with all of the original errors kept in. Here were the results. The first was that the literal accuracy was extremely high. There weren’t many cases wherethe software had heard one word incorrectly and written down another. But the other result was that the readability of this column wasrather bad. Obviously, the blame is not with the technology at all, which turns out to be rather good. Speaking into writing relies on a better human brain than the one we currently possess. Writing is hard. There’s a reason it can’t be done at the speed of speech, in real time.To clarify the matter, this time paragraph breaks were added after the whole writing. Punctuations (标点) had to be spoken aloud, and after a full stop, the first word in the new sentence was capitalized automatically. Some minor punctuation marks were added to make it clearer. To improve accuracy, people “trained” the software beforehand, reading a prewritten passage aloud. Actually it turns out to be more effective. All of these ensure the satisfactory completion of turning speech into writing.Language is the most important tool for human interaction, and voice is one beautiful part of language. With the maturity of modern technology, it has given birth to a great change in the human-computer voice interaction.8. According to the passage, which helps to turn speech into writing in terms of style?A. There is careful planning in advance.B. Errors and broken sentences are avoided.C. People type words as fast as they say them.D. The writing contains more prepared phrases.9. To achieve better results, the author mentions some changes for ______.A. processing errors in a column.B. adding minor punctuation marks.C. increasing the number of brief notes.D. integrating short paragraphs in writing.10. The author suggests that ______.A. human brains are responsible for poor dictated writing.B. writing with voice promises to improve the quality of writing.C. writing is an unnatural act that can hardly be learned and improved.D. technology has a long way to go in the human-computer voice interaction.11. What is the passage mainly about?A. Why people fully intend to turn speech into writing.B. What role voice technology plays in improving readability.C. Where the human-computer voice interaction is at an advantage.D. How voice technology enables the change from speech into writing.D“My P.E. teacher taught me maths.”It has been a common joke for years but when a P.E. teacher applied for the head-teacher job, many parents worried that “the joke could come true”. Some parents asked, “Does the P.E. teacher know maths and English?If not, how is he supposed to tutor the students?” But there were still parents who believed P.E. teachers had more time to discipline the students since they didn’t have many classes.This concern is actually a “subject bias”, that is, choosing a P.E. teacher as the head-teacher is not good for the students’ grades since he doesn’t know Chinese, maths, or English. It is acceptable for Chinese teachers, maths teachers and English teachers to be head-teachers because these subjects are important to entrance exams and scores. Such a concern reflects parents’ anxiety in the current educational environment, which tends to link the head-teacher’s responsible subject with the facts whether the school cares about the class and the children’s performances in the subject.Many people care about their kids’ academic performances only. They don’t care about their kids’ P.E. performance at all. Even if kids have P.E. classes, parents care little. P.E. teachers are in humble position and their classes are often occupied by other teachers. Of course, if students, P.E. performance is related to grades and entrance exams, parents won’t mind “a P.E. teacher being the head-teacher”.At the moment, P.E. is gradually included in entrance exams.In terms of high school entrance examination,Guangzhouwill launch a new high school entrance exam which includes P.E. performance and Health examination in 2021, raising the score to 70 points.In terms of the college entrance examination, universities having the right of independent enrollments added P.E. tests to their entrance exams in 2019. This practice is seen as an important signal that the assessment of physical fitness and athletic ability, which are important aspects of a student’s overall quality, may be included in the college entrance examination in the future.We hope that it’s a trend for P.E. teachers, music teachers and art teachers to become head-teachers.12. By saying “My P.E. teacher taught me maths”, what does the author intend to show us?A. It is just a joke that seldom happened in reality.B. P.E. teachers hardly assist students in maths.C. P.E. teachers are good at teaching maths..D. Parents doubt the ability of P.E. teacher.13. We can infer from paragraph 2 that a P.E. teacher .A. is of little benefit for students’ academic performanceB. is humbler than Chinese, math or English teachersC. reflects whether the school cares about the classD. gets unfairly judged due to the current educational system14. Why doesGuangzhouraise proportion of P.E. performance in high school entrance examination?A. To raise students’ awareness of physical health.B. To call on parents to pay attention to P.E. teachers.C. To test the overall ability of high school students.D. To make P.E. teachers equal with other teachers.15. What opinion does the author hold towards P.E. teachers working as head-teachers?A. Neutral.B. Unexpected.C. Supportive.D. Critical.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。

运动员穿着专用滑雪板，不带雪杖在助滑路上获得较大速度后从跳台水平飞出，在空中飞行一段距离后着陆。
如图所示，已知某运动员连带身上装备的总质量m =50kg ，从倾角为θ=37°的坡顶A 点以速度v 0=20 m/s 沿水平方向飞出，到山坡上的B 点着陆，山坡可以看成一个斜面（不计空气阻力，取g =10 m/s 2，sin37°=0.6，cos37°=0.8）。
求： (1)运动员在空中飞行的时间t ； (2)AB 间的距离s 。
(3)运动员落到斜坡上的B 点后顺势下蹲以缓冲使他垂直于斜坡的分速度在很短时间 △t=0.2s 的时间内减小到零。
试求缓冲过程中滑雪板受到斜坡的平均支持力的大小。
