When Jenny Benson was eight, her mother took her to soccer practice for the first time. “She’s never played soccer before,” Mrs Benson told the coach.“I’m not sure how she’ll do.”Jenny ran onto the field and joined the other players. Over the next hour, Mrs Benson and the coach watched as Jenny out-ran many of the more experienced players.“I knew then that soccer would be Jenny’s sport.” Mrs Benson recalls. And she was right.It may have helped that Jenny had spent much of her time trying to keep up with her three brothers.“I wanted to be just like them,” Jenny says.“My family has inspired me for my entire life.”Jenny has retired from the United States women’s national soccer team. She started out on her professional career in the Philadelphia Charge, a team in the Women’s United Soccer Associ ation (WUSA).Later on, she joined FC Energy Voronezh, and then New Jersey Wildcats.When the WUSA was being formed, league officials watched many college soccer games, looking for players good enough to join the league. They were very interested in Jenny, who played for the University of Nebraska.“Throughout that college season, I knew I was being watched,” Jenny says, “I knew I couldn’t be perfect, so I just tried to be very consistent and have fun.”As a professional, Jenny relied on her focused but fun-loving attitude. “In a game, I try never to put too much pressure on myself. The more I concentrate on having fun, the better I play.” She says. “I have good and bad days, just like everyone else, but I know the sun will always come up after a bad day. So all I have to do is to adjust myself, either to the change of my inner feelings or to the change of circumstances.That helps me get through anything.”1.

Drrinnggg! That’s the sound that kids all over the country hate to hear-the alarm bell. The new school year has just started and children across the UK have to wake up early in the morning to go to school.But students at one school in northeast England are lucky. They can lie in bed for an extra(额外的)hour before they go to school. Monkseaton High School has been allowing its pupils to come into school an hour later than other schools.The headmaster, Dr Paul Kelley, says that this new approach(方式) helps students pay more attention to their lessons in class. He feels that young people are more energetic and can perform better for the rest of the day. And he adds that for their school students, a late start at school may be better than an early one.Dr Kelley tells the BBC that teenagers don’t perform very well in the morning and their need to sleep is biological(生物的). It seems that this new approach to teaching shows positive(积极的) results. The number of students who sleep in class drops quickly. Besides, the school has already seen a drop in the number of pupils who play truant(逃学) by 27%. More importantly, Dr Kelley also says that exam results have improved by 20%-30% over the past year.Classes at Monkseaton High School begin at 10 a.m. and finish at 3:40 p.m. However, the school opens from 8 a.m. to 5 p.m. The students can come early and leave late if they want.1. What is this passage?A.A news report. B.A speech.C.A story. D.A notice.2. What is Dr. Paul Kelley’s opinion of the new approach?A.He gives no opinions about it.B.He has his doubts about it.C.He disagrees with it.D.He agrees with it.3. Which is NOT the positive result about the new approach?A.The exam results have improved.B.Fewer and fewer students sleep in class.C.Most students get to school earlier.D.The number of pupils who play truant drops.4. When do classes usually begin in schools in the UK according to the passage?A.At 8:00 a.m. B.At 9:00 a.m.C.At 10:00 a.m. D.At 11:00 a.m.4. When school started on that warm August day, I threw myself into everything I did, including playing volleyball. I decided to become beautiful, or at the very least, skinny. I stopped eating completely. Soon I began losing weight, which thrilled me, and I even grew to love the tiredness and lightheadedness( 头晕)that came with my poor diet, for those feelings meant that I was winning.As the season progressed, things had become tense between my head volleyball coach, Coach Smith, and me. She felt that something was wrong with my health. She talked with me about my eating and was angry that I wouldn’t listen to her when she tried to make me eat. She tried to persuade me in a determined way and so we fought constantly. Then my hunger started to affect my performance. I was so tired that practice and games were becoming a struggle. One afternoon, with hurt in her eyes, Coach Smith asked me what I had eaten and I told her nothing yet. She looked at me, disappointment in her eyes, knowing she couldn’t make me stop, and walked away.A couple of weeks later I attended a formal dinner for our volleyball team. I stood there as my coach managed to say something nice about me. I realized then that I had ruined my senior year by being disrespectful, and I had probably ruined hers as well. So that evening I wrote her a letter apologizing and thanking her.Then one Saturday, as I was reading in the library, I felt someone gently take my arm and say softly, “Lynn Jones, how are you doing?” I looked up and saw the familiar face. “Thanks for the letter,” she said. “It meant a lot.” When I think of a coach, I think of someone above me, someone who gives instruction — not a friend. But Coach Smith is different, and, like any other good friend, she dealtwith my problem in a determined way even when I hated her for it at that time. I didn’t deserve her kindness, but she gave it anyway. I will forever be gratefulfor her help, and now for her friendship.1. How did the author feel when she ate a poor diet and had a sense of tiredness?A. Funny. B. Nervous. C. Proud. D. Ashamed.2. The author fought with Coach Smith because .A. she refused to go on a diet . B. she causedfailure of her team.C. she kept her ideaof losing weight.D. she changed thetraining course.3. Why did the author write a letter to Coach Smith?A. She felt sorry for eating too little food.B.She was grateful for Smith ’ s care for her health.C. She decided to improve her performance.D. She wanted to build a close relationship with Smith.4. What is the best title for the text?A. My Way of Losing Weight. B. A Fight with MyCoach.C. A StrictVolleyball Coach.D. UnexpectedFriendship.5. Taking pressure off sports competitionsSports are a great way to have fun and stay active. Competitions can make sports more exciting. But because somebody wins and somebody loses competitions can also make kids be under pressure. 1 But too much pressure is bad news. Read on to learn more about sports pressure.What is a competition?There are different kinds of competition in sports. 2 For example, a swimmer might compete individually, but the person’s score may also contribute to a team’s score. What all sports competitions have in common is that all of the competitors want to win. 3Why do I feel under pressure?Do you ever have “butterflies” in your stomach? It’s that nervous feeling some people get when starting to attend a new school or preparing for a big soccer match. Believe it or not, the best player on your team gets nervous before a big game. 4 Feeling a little excited or nervous is OK, though. This helps your body and mind get ready to compete. But if you’re getting so nervous that you aren’t having much fun, it’s time to figure out why.How can I deal with pressure?When you’re competing in sports, you need a lot of energy. 5 Be sure to go to bed on time. And don’t forget to eat well on game day. Try to attend all of your team’s practices. By practicing, you’ll improve your playing skills. The more prepared you are, the better you’ll feel and the more fun you’ll have.6.

Why was Sam late for his job?A. Because he was ill.B. Because he got up late.C. Because he was caught in a traffic jam.D. He was busy applying for a new job.5. The main idea of this passage is ________.A. Sam Maynard saved his job with humorB. humor is important in our livesC. early bird gets the wormD. humor can solve racial discriminations6. The phrase “clamped off” in Paragraph 3 means ________.A tried to hold back B. tried to setC. chargedD. gave out7. Which of the following statements can we infer from the passage?A. Many lose life’s battles for they are lacking in a sense of humor.B. It wasn’t the first time that Sam came late for his work.C. Sam was supposed to come to his office at 8:30.D. Humor is the most effective way of solving problems.CAccording to the study posted onScienceDirect, gardening just two to three times a week increase the benefits of better well-being as much as possible and lower stress levels.The research explored why residents engaged with gardening and the extent to which they recognized any health benefits from the activity.A questionnaire was handed out electronically within theUK, with 5,766 gardeners and 249 non-gardeners responding. Data was collected on factors including garden typology(类型学), frequency of gardening and individual awareness of health and well-being."This is the first time the dose response(剂量效应)to gardening has been tested and the evidence from the survey strongly suggests that the more frequently you garden, the greaterthe health benefits," said Royal Horticultural Society (RHS) lead author Dr Lauriane Chalmin-Pui. In fact, gardening every day has the same positive impact on well-being than undertaking regular and powerful exercise like cycling or running.When gardening, our brains are pleasantly entertained by nature around us. Gardening takes our attentionaway from ourselves and our stresses, therefore, it helps restore our minds and reduce unfavorable feelings.Improving health, however, was not the main motive power to garden, but rather the direct pleasure gardening brought to the participants."Gardening is like effortless exercise because it doesn't feel as exhausting and hard as going to the gym, for example, but we canexpendsimilar amounts of energy," Chalmin-Pui added.Most people say they garden for pleasure and enjoyment, so people who like gardening may be easy to be addicted to it. However, this sometimes may become a piece of good news, from the aspect of mental health. "We hope all the millions of new gardeners will be getting their daily gardening and feeling all the better for it. " Chalmin-Pui said in the interview.8. What can be inferred about gardening from the survey?A. Improving health is the aim of the participants.BGardening makes no difference to health.C. Health benefits from frequent gardening.D. Too much gardening always does harm to health.9. What does the underlined word "expend" mean in paragraph 7?A. Consume.B. Make use of.C. Increase.D. Save.10. Why do so many participantslike gardening?A. It isn't exhausting.B. It is good for health.C. It brings pleasure.D. It is like going to the gym.11. What is Chalmin-Pui's attitude to the new gardeners' gardening?A. Carefree.B. SupportiveC. Tolerant.D. Indifferent.DDolores Huerta has worked hard most of her life to help other people. She has helped change things so that others can have a better life.Dolores grew up in California. She was a good student and liked school. After she finished high school, she went to college and studied to be a teacher. After college, she became a teacher. Dolores noticed that many of her students were not getting enough food to eat.

2020-2021学年梅州市梅县高级中学高三英语上学期期中考试试题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AFour Best Hikes in the WorldThere's nothing like getting out and getting some fresh air on a hike. No matter whether your idea of a hike is a leisure walk or climbing the highest mountain on Earth, we've got you covered. Below are four best hikes inthe world.Torres del Paine W CircuitLocation (位置): Patagonia. ChileDistance: 37 + milesTime: 5~6 daysBest time to go: October to JanuaryThe W Circuit is one of the most recommended hikes you'll find. Not only will you appreciate the diverse landscapes and striking granite pillars (花岗岩柱子), but you'll probably meet some new friends along the way.Grand Canyon Rim - to - Rim HikeLocation: Arizona, the United StatesDistance: 48 milesTime: 1~3 daysBest time to go: May to June, September to OctoberThere's no better way to experience one of the greatest wonders in the world. Located in one of the USA's most beautiful parks, the views are ly appealing. Just make sure you're prepared for the challenge.Trek to PetraLocation: JordanDistance: 47 milesTime: 5~ 6 daysBest time to go: October to AprilTake the road less traveled through the Kingdom of Jordan and experience one of the seven wonders of theworld. Hike through canyons, gorges and ridges, and see tombs and temples along the way all while avoiding crowds of tourists.Yosemite Grand TraverseLocation: California, the United StatesDistance: 60 milesTime: 6~7 daysBest time to go: July to SeptemberKnown for some of the best hiking in the world, Yosemite National Park is famous for its views and huge sequoia (红杉) trees. Praised byNational Geographic, the Yosemite Grand Traverse will take you through waterfalls and green mountaintops.1.Which of the following is the best time for the hike in Patagonia, Chile?A.AprilB.MayC.AugustD.December2.Where should you go for a less crowded hike?A.JordanB.Patagonia, ChileC.Arizona, the United StatesD.California, the United States3.What can you do along the Yosemite Grand Traverse?A.Plant sequoia treesB.Appreciate waterfallsC.Visit local templesD.Climb granite pillarsBConcrete is the world's most consumed material after water. Because it already surrounds us in the built environment, researchers have been exploring the idea of using concrete to store electricity—turning buildings into giant batteries. The idea has been gaining ground as we have come to increasingly rely on renewable energy from the wind and sun: rechargeable batteries are necessary when the breeze dies down or darkness falls.Experimental concrete batteries have only managed to hold a small part of what a traditional battery does. But one team now reports in Buildings that it has developed a rechargeable original model that could represent a more than 900 percent increase in stored charge, compared with earlier attempts.A live-in concrete battery might sound unlikely. Still, "you can make a battery out of a potato," notes Aimee Byrne. In a future where sustainability is key, she likes the idea of buildings that avoid waste by providing shelter and powering electronics.Although the new design stores more than 10 times as much power as earlier attempts, it still has a long wayto go: 200 square meters of it "can provide about 8 percent of the daily electricity consumption" of a typical U.S. home, Zhang says.This is not enough to compete with today's rechargeable devices. "We're getting milliamps (毫安) out of concrete batteries—we're not getting amps (安培), "Byrne says." We're getting hours as opposed to days of charge." But she adds that" concrete batteries are completely in their childhood, compared to other battery designs." The earliest batteries were simple andbulky. Researchers experimented with new materials and designs for more than a century to develop today's small devices. Byrne suggests concrete-based energy storage could undergo a similar evolution. "The whole idea is that we're looking far into the future," she says. "We're playing the long game with it."4. What can we learn about the concrete batteries?A. They become increasingly renewable.B. They are the most consumed batteries.C. They are being developed by researchers.D. They will replace energy from the wind and sun.5. Why does Byrne mention a battery out of a potato?A. To show it is easy to build concrete batteries.B. To argue it is possible to develop concrete batteries.C. To make her statement more interesting.D. To call on people to protect the environment.6. What does the underlined word "bulky" in Paragraph 5 mean?A. HeavyB. CheapC. EfficientD. Small.7. What doesByrne think of concrete batteries?A. They beat today's rechargeable devices.B. They are simple and bulky.C. They have a doubtful future.D. They have a long way to go.CIf there is no difference in general intelligence between boys and girls, what can explain girls’ poor performance in science and math?It hasbeen suggested that girls do not take math courses, not because they are difficult, but for social reasons. Girls do not want to be in open competition with boys because they are afraid to appear less feminine (女性的) and attractive (有魅力的).However, there are still more high-achieving boys than girls when taking math exams. This difference appears to be worldwide. Biological explanations have been offered for this, but there are other explanations too.Perhaps the difference which comes out during the teenage years has its roots in much earlier experiences.From their first days in kindergarten, boys are encouraged to work on their own and to complete tasks. Facts show that outstanding mathematicians and scientists have not had teachers who gave answers.Besides, there can be little doubt that teachers of math and science expect their boy students to do better at these subjects than their girl students. They even appear to encourage the difference between boys and girls. They spend more time with the boy students, giving them more time to answer questions and working harder to get correct answers from them. They are more likely to call on boys for answers and to allow them to take the lead in classroom discussion. They also praise boys more frequently. All of this seems to encourage boys to work harder in science and math and to give them confidence that they are able to succeed.Such a way of teaching is not likely to encourage girls to take many math and science courses, nor is it likely to support girls who do. When it comes to these subjects it seems certain that school widens the difference between boys and girls.8. Why does the author raise a question in paragraph 1?A. To find differences between boys and girls.B. To explain the poor performance of girls.C. To ask readers a question.D. To introduce the topic.9. The text mainly discusses ________ reasons for the difference between boys and girls in scientific achievements.A. biologicalB. personalC. socialD. historical10. What does the text say about great mathematicians?A. Their teachers did not offer answers to them.B. They started learning math at an earlier age.C. They showed mathematical abilities in their teenage years.D. Their success resulted from their strong interest in math.11. The author would probably agree that ________.A. boys and girls learn in the same wayB. boys and girls are equal in general intelligenceC. girls are more confident in themselves than beforeD. girls should take fewer science courses than boysDSomeday soon an emoji (表情符号)might really save lives.Hiroyuki Komatsu is a Google engineer who suggested adding a series of new emojis to the standard emoji library. It could help those with food allergies (过敏)understand what they are eating anywhere inthe world. Emojis should cover characters representing major food causing allergies. They make people understand what are used in foods even in foreign countries and safely select meals.Emojis are universal because they are chosen and developed by the Unicode Consortium, a non-profit company that oversees, develops and maintains how text is represented. This is in regards to all software products and standards. It's thanks to the Unicode Standard that when you text a friend six pizza emojis, they’ll see those six pizza pieces on their phone. This is true regardless of whether they use an iPhone or an Android.Because emojis are everywhere and visual(视觉的),they could be helpful for restaurants and food packaging designers. They can communicate whether a product is made with common causing-allergy food. But as Komatsu’s advice argues, many of the most common causing-allergy foods are missing or poorly represented by the present emoji library. For example, there is an emoji for octopus, but nothing for squid. There is a loaf of bread that could symbolize grain, but a picture of wheat could be clearer. The emojis can be more direct when symbolizing foods.It’s not uncommon for the Unicode Consortium to add new emojis to the library: several food-related emojis were put into use last June, including some long-waited food emojis. Apple included support for multiracial emojis in a recent iOS update. An artist even recreated Moby-Dick in emoji characters. Some might be sorry for the continuing death of the written word if Komatsu’s suggestion is accepted, but look on the bright side: if you ever see that happy poop on a box, you’ll know to stay away.12. How will emojis save lives according to the text?A. By showing what the food contains visually.B. By telling the safest places in the world.C. By teaching people how to treat allergies.D. By adding standard emojis about safety.13. What does paragraph 3 mainly tell us?A. Emojis have the same meanings around the world.B. The Unicode Consortium is a non-profit company.C. What emojis represent is different in different places.D. Different mobile operating systems have different emojis.14. What can be the reason for Komatsu’s advice?A. Emojis are easy to mix up.B. Present emojis are not enough.C. Emojis can't interest most users.D. Emojis can't represent foods directly.15. What is the author’s attitude to Komatsu's suggestion?A. Doubtful.B. Worried.C. Supportive.D. Uninterested.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。

Omega Speedmaster watches have been an important part of space travel since NASA chose them for its moon landing in 1965. Other watches had failed required tests. Omega gave its gold Speedmasters to the astronauts at a dinner in 1969 before the landing. Another less costly type of silver Speedmasters will be sold at $ 9,650. It carries a picture of Aldrin stepping down from the moon lander.Something for children-as well as adults — is the NASA Apollo 11 moon lander set. Made by Lego, it is a group of small pieces to put together to make a model of the moon lander.Other things for sale include the anti-gravity Fisher Space Pens,developed just for the Apollo 11 mission. They work even when writing upside down. Now Fisher Space Pen Company has a limited-edition pen for sale at anout-of this-worldprice: $700, with real material from the Apollo 11 spacecraft.Back in 1969, companies were quick to show their Apollo 11 connections with media and advertisements. The food company Stouffer’s made sure consumers knew it provided food for Apollo 11 astronauts once they returned to Earth. It started the ad campaign “Everybody who’s been to the moon is eating Stouffer’s”. Fifty years later, the company is celebrating with a media campaign to share some recipes from 1969.Marketing experts David Meerman Scott says, “Since 1972,we’ve gone around and around the earth many times, and it is not interesting to people any more. I’m not sure whether they can accept such crazy prices. NowNASA has had plans to go to Mars in the 2030s and marketing efforts for a NASA Mars mission should be in development.”4. What can we learn about the gold Speedmaster watch?A. It will be sold at $34,600.B. NASA bought itats9,650.C. It has Aldrin’s picture inside.D. It was chosen by NASA in 1969.5. What does the underlined word “out-of-this-world” in paragraph 4 mean?A. Extremely fair.B. Surprisingly high.C. Really low.D. Truly worthwhile.6. What does David Meerman Scott mean?A. It is a waste of money to go around and around the moon.B. People will be interested in the products connected to Apollo.C. Since 1972,governments have lost interest in moon explorations.D. The event of going to Mars will be another good chance to advertise.7. What is the author’s main purpose in writing the text?A. To show how to design the best advertisement.B. To forecast the sales of the products in the text.C. To introduce some of the products connected to Apollo 11.D. To celebrate the 50th anniversary of the first moon landing.CBritish anthropologists (人类学家) Russell Hill and Robert Barton of the University of Durham, after studying the results of one-on-one boxing, tae kwon do, Greco-Roman wrestling and freestyle wrestling matches at the Olympic Games, conclude that when two competitors are equally matched in fitness and skill, the athlete wearing red is more likely to win.Hill and Barton report that when one competitor is much better than the other, colour has no effect on the result. However, when there is only a small difference between them, the effect of colour is enoughtipthe balance. The anthropologists say that the number of times red wins is not simply by chance, but that these results are statistically significant.Joanna Setchell, a primate (灵长目动物) researcher at the University of Cambridge, has found similar results in nature. She studies the large African monkeys known as mandrills. Mandrills have bright red noses that stand out against their white faces. Setchell’s work shows that the powerful males — the ones who are more successfulwith females — have a brighter red nose than other males.As well as the studies on primates by Setchell, another study shows the effect of red among birds. In an experiment, scientists put red plastic rings on the legs of male zebra finches and this increased the birds’ success with female zebra finches, Zebra finches already have bright red beaks (鸟喙), so this study suggests that, as with Olympic athletes, an extra flash of red is significant. In fact, researchers from theUniversityofGlasgowsay that the birds’ brightly coloured beaks are an indicator of health. Jonathan Blount, a biologist, andhis colleagues think they have found proof that bright red or orange beaks attract females because they mean that the males are healthier. Nothing in nature is simple, however, because in species such as the blue footed booby, a completely different colour seems to give the male birds the same advantage with females.Meanwhile, what about those athletes who win in their events while wearing red? Do their clothes give them an unintentional advantage? Robert Barton accepts that “that is the implication” of their findings. Is it time for sports authorities to consider new regulations on sports clothing?8. According to their research. Hill and Barton conclude that ________.A. the colour of clothing has an effect on most sport eventsB. red should be the choice of colour for clothing in sportsC. red plays a role when competitors are equally capableD. athletes perform better when surrounded by bright red9. The underlined word “tip” in Paragraph 2 is closest in meaning to ________.A. achieveB. advanceC. keepD. change10. The example of the blue footed booby proves that ________.A. male birds use different body parts to draw attentionB. red is not the only colour to attract female birdsC. blue gives female birds the same advantageD. blue can indicate how healthy a bird is11. What can be inferred from the passage?A. The colour red gives male animals the most advantage.B. Male zebra finches prefer to have red plastic rings on their legs.C. Rules on sports clothing are going to be changed.D. Athletes wearing red may have an advantage over their opponents.DOne day about eight years ago in the departure lounge (休息室) of a flight from New York's LaGuardia airport to O'Hare in Chicago, I found a young boy in tears and his mother at his side also appeared upset, I walked to them and invited them to our VIP lounge.As it turned out, the boy, Miles and his mom were returning to their home in Kansas City. Miles has had some health problems. Though he had received more than thirty operations in a Jewish Hospital in New York, he would be back for more.Miles enjoyed spending his time in our VIP lounge looking at the entire wall filled with the pictures of many celebrities (名人) who often came to our office. We soon added Miles' picture to the wall among those celebrities.Among the celebrities, Miles like the country singer Garth Brooks best. Miles would just sit and stare at Garth's picture,Oneday, Mr. Brooks was waiting in the lounge for his flight. As he looked at the collection of photographs, Garth asked about the youngster with the big smile. We told him about Miles. We also told him how much Miles loved and respected (尊重) him. He nodded and left.About six months later, Garth was going to be performing in Kansas City and he asked our workers to help him get in touch with the family. He wanted Miles to be his guest. That evening, not only did Miles sit in the front row, but he and Garth also had a private meeting after the performance.Although Miles would receive many more treatments after that special evening, his smile greeted us with every following visit. The face of a sick boy was changed by the joy of a stranger.12. What does the author probably do?A. A worker at an airport.B. A killed photographer.C. A country music singer.D. A doctor in a Jewish hospital.13. What did Miles enjoy doing in the VIP lounge?A. Interviewing celebrities he saw there.B. Seeing pictures of celebrities on the wall.C. Drawing pictures of the celebrities there.D. Singing together with his favorite singer.14. Which words can best describe Garth Brooks?A. Determined and generous.B. Proud and selfish.C. Kind and helpful.D. Powerful and rich.15. What can be the best title for the text?A. Importance of Good ServiceB. Kindness from StrangersC. A Serious Health ProblemD.
