Walking is so much a part of the lifestyle that it is seen as the most important part of thesuper-healthy Mediterranean diet.Studies have found that it may be one of the reasons the Mediterranean diet can reduce the risk for some diseases like diabetes, high cholesterol, heart disease, stroke and some cancers – all the while strengthening bones, improving brain health, preventing dementia (痴呆) and helping with healthy weight loss.Now you can add another reason to take a post-meal walk – it may lower your blood sugar. That trip doesn’t need to take up a huge amount of your time either: Walking as little as two to five minutes after a meal can do, according to a 2022 study in the journal Sports Medicine.Standing after a meal can help, too, but not as much as putting one foot in front of the other, said study coauthor Aidan Buffey, a doctoral student in sport sciences department at the University of Limerick in Ireland.“Standing on and off throughout the day and after meals reduced blood sugar on average by 9.51% compared to long hours of sitting. However, light-walking throughout the day saw a greater reduction of blood sugar by an average of 17.01% compared to long hours of sitting,” Buffey said.“This suggests that breaking long hours of sitting with standing and light-walking throughout the day is good for blood sugar levels. Standing is good, but walking is better,” he added.6.What is the purpose of Paragraph 1?A.To introduce a lifestyle.B.To warn the readers.C.To lead in the topic.D.To prove an opinion.7.What benefits can the Mediterranean diet bring to people EXCEPT ______?A.Losing appropriate weight B.Making bones strongerC.Preventing the risk for diseases D.Improving brain health8.What does “putting one foot in front of the other” in paragraph 4 mean?A.Standing.B.Sitting.C.Walking.D.Lying.9.How did Aidan Buffey draw his conclusion?A.By doing surveys (调查).B.By comparing the data (数据).C.By doing experiment.D.By referring to other studies. 10.What is the best title for the text?A.Walking can help lower blood sugar B.There are reasons to stick to walkingC.Mediterranean diet is super healthy D.Long hours of sitting after meal is a bad habit“Our aim is to take our art to the world and makepeople understand what it is to move,” said David Belle, the founder of parkour (跑酷).Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond’s wonderful performances that the sport has become popular worldwide.Yes, that’s parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.Overcoming all the obstacles on the course and in life is part of the philosophy (理念) behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life, to reach the destination successfully. A parkour lover said, “I love parkour because its philosophy has become my life, my way to do everything.”Another philosophy we’ve learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself that you earn energy and confidence.11.Parkour has become popular throughout the world because of .A.its founder, David Belle B.the film, Casino RoyaleC.its risks and tricks D.the varieties of participantsA.streets B.objectsC.barriers D.roofs13.Which of the following is true of parkour?A.It challenges human abilities.B.It is a good but boring sport.C.It needs special training.D.It is a team sport.A.they can ask for help B.they may choose to escapeC.they should run to extremes D.they must learn to survive15.Which of the following is the philosophy of parkour?A.Sports and extremes.B.Excitement and popularity.C.Dreams and success.D.Determination and freedom.二、七选五Today, people are working from home more than ever. As a result, many dogs are enjoying a lot more time with, and attention from, their owners. Dog adoption (收养) rates have skyrocketed as people seek enjoyment and companionship. But what will happen when life eventually returns to normal? 16 .Teach puppies alone time17 . Otherwise, they may become anxious when they are alone, which can result in damaging behavior such as chewing on furniture and digging up plants in the garden. Teaching your puppy to be comfortable alone right from the start will help you avoid separation issues in future. Pleasing as it is to let your cute puppy follow you around, this can lead to them becoming overly dependent and potentially anxious when left alone.Set up a playpen or CrateAn enclosed space will keep them safe when you’re not in the same room. Allocate (分配) some time each day to leave your puppy alone – after playtime is perfect. Allow them an opportunity to toilet and then give them something safe to chew on to help them settle. If you are planning for your dog to spend time outside during the day, it is essential that you set this up from the beginning.18It’s important for adult dogs to also spend time alone. When you are home, put your dogoutside for short periods while offering a chew (咀嚼) toy, or encourage them to settle on their bed or in a crate while you move around different parts of the home. Setting up and maintaining an exercise routine (惯例) will be important once you start leaving home more, or your dog may become bored and possibly damaging.Establish good chew habitsTeach your puppy or dog what is acceptable for them to chew. Only give them toys that are clearly different from household items. 19 . When you want your dog to have some quiet time, give them a safe chew toy so they learn to connect this time with something positive. When you leave home, give them a chew toy to help them relax and keep them busy.Train your dogThis should include teaching the basics of “sit”, “stay”, and “down” but also training them to go to their bed and stay in position when requested. 20 .A.Create a routineB.Maintain appropriate exerciseC.Dogs like routine because it makes them feel safeD.Chewable toys that can be stuffed with a treat like peanut butter are a good choice E.Trick training is also a nice way to use any extra time to develop the bond with your dogF.These tips will help you raise a puppy or train a dog to be content when you are not aroundG.Dogs are social creatures and need to learn some skills to be comfortable when left unattended三、完形填空Friday night meant a family dinner for me at home. There would be discussions andlight the candles with my mom.Years later, my father passed away, and then my mother insisted on going to live in a care home. I seemed to be totally 28 from the boring tradition, but I didn’t feel 29 . I missed the chicken soup. Although I have her recipe, I’ve never actually 30 the soup myself. I missed the warm-lighted candles. Standing together, we’d make 31 with our hands around the lit candles, bringing the light into our hearts.That’s why I accepted 32 when my husband advised to 33 the tradition “I can help with the soup.” If there’s one thing I’ve 34 , these family traditions are really worth cherishing before they 35 , from the chicken soup recipes to lighting candles.21.A.remembered B.hated C.enjoyed D.chose 22.A.early B.late C.already D.again 23.A.instructions B.applications C.organizations D.solutions 24.A.natural B.formal C.dull D.creative 25.A.tradition B.comfort C.schedule D.course 26.A.elected B.turned C.dressed D.set 27.A.point B.dishes C.food D.forks 28.A.protected B.freed C.recovered D.discouraged 29.A.lost B.happy C.curious D.nervous 30.A.served B.stirred C.made D.poured 31.A.fortunes B.efforts C.circles D.noises 32.A.immediately B.generally C.widely D.regretfully 33.A.throw away B.go over C.check in D.take over 34.A.controlled B.forgotten C.admitted D.learned 35.A.exist B.improve C.disappear D.continue四、用单词的适当形式完成短文阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

2023-2024学年福建省福州市八县市协作校高二下学期期中联考英语试题

2023-2024学年福建省福州市八县市协作校高二下学期期中联考英语试题When it comes to tricks in life, the following will be of great help, which might surprisingly end up working the magic.Hooks that helpThere’s nothing worse than throwing something into the trash bin and watching the garbage bag fall in with it. To prevent this, stick two wall hooks onto the outside of your bin(one on either side), positioned so they face downward. The next time you replace the grocery bag, loop its handles through the hooks and no matter how full the bag gets, it’ll never drop to the bottom of the bin again.Easier garbage storageYou have probably encountered this: after filling the bag with trash, it forms a vacuum (真空) seal so tight that it’s a struggle to lift the bag out once it’s full. What to do? Punch a couple of small holes in the sides, a few centimeters above its base. The holes will allow just enough airflow to make lifting out the trash a piece of cake.Instant bottle brushIf you have an ordinary kitchen sponge (海绵) and a fork, then you have everything you need for a DIY bottle brush. Pierce the narrowest edge of the sponge with the fork and slide the sponge down until the points of the fork are fully covered. You can now clean out the skinniest bottle with ease.Express dryingNeed washed load of laundry dried in a flash? Toss a clean, dry towel into the dryer along with all the wet stuff for the first 15 minutes of the cycle. It’ll absorb some of the moisture and speed up the overall drying time.1. What is the key to lifting trash bags?A.The fork. B.The hook. C.The brush. D.The holes.2. Why is a dry towel used in the laundry?A.To take in water. B.To tidy the dryer.C.To clean the clothes. D.To distinguish the wet stuff.3. What does the passage mainly talk about?A.Various means of saving money. B.Creative ideas on making life fun.C.DIY solutions for life’s little dilemmas.D.Different ways to promote cooking skills. I’m a layperson with a love of science who occasionally reads science magazines. My approach was from an author’s angle, spending months on research before writing a single word for Pig Heart Boy.So where did I get the idea? Whenever I attend a school event, that question is asked. The answer is simple. Back in the mid 1990s, I read a newspaper article written by a doctor who guessed that we would eventually have to turn to xenotransplantation (异种器官移植) as a possible solution to the lack of human organ donors. It left my mind filled with questions. What are the consequences? Dowe really have the right to treat animals as me re organ sources for humans? So I headed to my nearest bookshop and bought all the books I could on heart transplants in particular.I’ve found questions are one of the best plac es to start from when writing a novel. In my story Cameron, who needs a heart transplant, knows he is unlikely to see his next birthday unless he receives one, but he is a long way down the waiting list. When a genetically modified (GM) pig’s heart is offered by a pioneering doctor, Cameron decides to go for it —and his new heart completely changes his life in unexpected ways.Now some people think that the subject matter is not suitable for children, criticizing the cruel and inhuman ways of xenotransplant ation. I completely disagree. As a children’s author, it never ceases to amaze me how some adults underestimate what subject matter will interest and stimulate children.I wanted to write a story that provided no right or wrong answers, a story that would allow the reader to walk in Cameron’s shoes for a while and think about what decisions they would make and how they would react if they too were faced with his situation.Fictional stories that explore new ideas when it comes to STEM (science, technology, engineering and mathematics) subjects also have a part to play in enriching our children’s reading and learning. Various studies have shown that reading fiction enhances our children’s ability to grasp new concepts. Pig Heart Boy was my attempt to incorporate science possible into a believable, thought-provoking (令人深思的) story.4. Where did the author get inspiration from to write Pig Heart Boy?A.A school event. B.A news item.C.Science magazines. D.Books on heart transplants.5. What might be a major concern of those who disagree with Pig Heart Boy?A.Animal rights. B.GM technology.C.Organ transplant risks. D.Organ shortage crisis.6. What are the last two paragraphs of the text mainly about?A.Ways of tapping children ‘s intelligence.B.Potential application of fictional stories.C.Supporting evidence for justifying the book. D.Influence of fictional stories on STEM subjects.7. What is Pig Heart Boy?A.An author profile. B.A science fiction novel.C.A guidebook to xenotransplantation. D.An essay on writing children’s literature.“Anxiety.” The very word invites discomfort. Its effects—shortness of breath, pounding heart, muscle tension—are outright upsetting. But, as a clinician, I find that we tend to miss out on many valuable opportunities presented by this human emotion. In and of itself, anxiety is not deadly, nor is it a disease. Quite the contrary: it is an indicator of brain and sensory health. Once we accept that it is a normal, though uncomfortable, part of life, we can use it to help us.We all know working out at the gym is hard. By nature, a “good workout” is uncomfortable, since it involves pushing our physical strength past what we can easily do. The sweet spot of exercise is always a somewhat challenging experience. Similarly, if you want to be emotionally stronger, you need to face some tension. For example, one effective treatment for fear is exposure therapy (疗法), which involves gradually encountering things that make one anxious, reducing fear over time.Humans are social creatures. When my patients learn to open up to their partners about their anxieties, they almost always report a greater sense of emotional closeness. Also, as international relationship expert Sue Johnson teaches, when we express our need for connection during challenging moments (e.g., “I’m having a hard time right now and could really use your support”), it creates greater connection and turns our anxiety into love.From time to time, we find ourselves at the end of our rope. Our responsibilities pile up, our resources break down, and we feel uncomfortably anxious—what we’re experiencing is called stress. Simply put, the demands placed upon us outweigh our available resources, just like a set of scales (天平) going out of balance. Focusing on work and pretending everything is OK only leads to disastrous results. Medical treatment for stress may function for a while, but it tends to make things worse in the long run. The only solution to deal with stress is to do the mathematics to balance the scales.8. What does the author say about anxiety?A.It is an invitation to diseases.B.It indicates stable mental health.C.It costs us many valuable chances.D.It is a natural emotional expression.9. Why does the author mention “good workout” in paragraph 2?A.To prove how exercise influences emotions.B.To suggest an effective way to challenge limits.C.To explain how anxiety builds emotional strength.D.To show a positive connection between mind and body.10. What is paragraph 3 mainly about?A.The key to closene ss is partners’ support.B.Sharing anxieties improves relationships.C.Humans are defined by their social nature.D.Expressing feelings keeps us off anxieties.11. According to the last paragraph, how can we deal with stress?A.Devote more energy to our work.B.Increase resources available to us.C.Seek professional medical treatment.D.Master advanced mathematical skills.The science of why insects gather around lights at night has never been nailed down. Popular theories propose that moths and other insects navigate (导航) by the moon and mistake lamps for moonlight, or that the insects fly towards light to escape coming danger. Now researchers believe they have a more convincing answer: contrary to current theories, insects are not attracted to light from far away, but become trapped if they fly close to an artificial light source.According to Dr Sam Fabian, study co-author and Imperial College London entomologist, moths and many other insects that fly at night evolved to tilt (倾斜) their backs to wherever is brightest. For hundreds of millions of years, this was the sky rather than the ground. The trick told insects which way was up and ensured they flew level. But then came artificial lighting. Moths found themselves tilting their backs to street lamps. This caused them to circle around the lamps endlessly, the insects trapped by their evolution.Fabian and his colleagues filmed insect flight paths around lights in the lab. The videos reveal that time and again, moths and dragonflies turned their backs to artificial lights, which appeared to greatly change their flight paths. If the light is above them, they might start orbiting it, but if it’s behind them, they start tilting backwards and end up flying in circles or diving toward the ground. Researchers have long warned that light pollution is a big driving force in the dramatic decline in insect populations. Moths and other insects that become trapped around lamps become easily caught by bats. The artificial lighting can also fool them into thinking it is daytime, causing them to bed down and skip a night’s feeding.There are, Fabian believes, helpful lessons from the research. “What this tells us is that the direction of artificial light matters. Could we change lighting environments to not trap i nsects? For we’re facing a massive decline in insects around the world, and artificial light at night is one of the factors that could potentially be leading to this decline,” Fabian said.12. What do the underlined words “nailed down” in paragraph 1 mean?A.Popularized widely. B.Discussed openly.C.Defined accurately. D.Explored academically.13. Fabian’s study found that moths circle around the lamps endlessly because ______.A.they can’t keep their balance.B.they use improper flight attitude.C.they lose track of which way is up.D.they are attracted to lights from far away.14. What is the significance of the research finding?A.It may lead to better conservation of insects.B.Natural enemies of insects will be got rid of.C.Artificial lighting will be greatly reduced at night.D.It may raise concerns for insects’ eating behavior.15. What is the text mainly about?A.Why insects lose their ability to fly at night.B.Why artificial light and evolution trap insects.C.How artificial light impacts insect populations.D.How insects evolved distinct strategies of flight.Why was school created? 16 Especially on test days, many students wonder exactly why they’re being subjected to such terrible and unusual punishment!If you’re honest with yourself, though, you know what a great place school is. 17 . Sure, tests can be stressful, but think of how boring life would be if you didn’t get to learn new things and see other people so often!Schools are not a new invention. You may have seen some old one-room schoolhouses that have been around for several hundred years or more. 18 .In fact, education dates back to the very first humans ever to live on Earth. Why? To survive, every generation has found it necessary to pass on its knowledge, skills, values, and traditions to the next generation. How can they do this? Education! Each subsequent generation (后代) must be taught these things.19 They educated young people within the family unit. Over time, however, populations grew and societies formed.Rather than every family being responsible for education, people soon found out that it would be easier and more efficient to have a small group of adults teach a larger group of children. 20 .William Gwyn Thomas, who used to be a dairy farmer in Lampeter, Ceredigion, has been cleaning trains at Carmarthen station for 25 years.Gwyn is still working with a team as ________as ever to clean anywhere between 18 and 26 carriages at night and is proud of what he does. “I didn’t expect I’d still be ________ at 80,” said Gwyn. “But I really love it, and I’ll _____when I feel I can’t do it.”Gwyn joined the train cleaning team in the late 1990s.

2021届福州高级中学高三英语上学期期中试卷及参考答案

2021届福州高级中学高三英语上学期期中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AAlex Palmer says he'll never forget his 13th birthday, not because of a gift or a party, but fire. “It made me realize how valuable life is,” said Alex, a seventh grader atMonroeDemonstrationSchoolinTulsa,Oklahoma.On April 18, Alex and many other kids from his school were riding home on a school bus when they suddenly saw smoke coming from the bus’ engine. “It was jaw-dropping,” he told reporters.By the time Alex and some other kids made it out the bus’ back door, the bus was already on fire. And some of their schoolmates were still inside. So he and some of the other older kids took action.“One little kid was slowing everyone down with his big backpack, ” eighth grader Destiny Fain said, “so I got it off and threw it to the side and helped to make sure all the little kids weren’t fighting or pushing. ”As that was going on, sixth grader Marketez Doyle-Smith reportedly helped another classmate who had trouble in breathing because of the smoke. “We saw our friend lying on the ground,” he said, “so we took our shirts off and waved them to get him some air to breathe.”Marketez also reportedly stopped a younger kid trying to get back on the bus to search for something he’d left behind. “We're all a family,” he told reporters. “So I went back to help the little kid.”Finally everyone made it off safely, thanks to Alex, Destiny, Marketez and several other kids. By later that day, they were already being called heroes. “I really don’t see it as being a hero,” Alex said, according to The World. “I see it as the right thing to do—helping others before you help yourself.”1. What happened on Alex’ s way home?A. The school bus was on fire suddenly.B. There was a party for Alex’s birthday.C. He received a gift from his classmate.D. Some classmates quarreled with each other.2. By saying "We're all a family.” Marketez probably meantA. We’re brothers in the same family.B. It’s our duty to help each other.C. We’re classmates in the same class.D. The thing left on the bus is mine.3. According to the last paragraph, Alex thought that heA. was not a brave student.B. had the right to do anything.C. had just done what he should do.D. hated to be called a hero by others.BImagine turning on the GPS and seeing an image of your car from above. As the car drives, the map follows along in real time, alarming you to any traffic, pedestrians,animals, or other things nearby. Routes and names of roads appear over the live stream. It's like the map has come to life.This type of map isn't available yet. But it could be soon. In 2014, the Worldview-3 satellites was launched into space. Even though it orbits Earth at more than 370 miles(600 km)away, it can capture images of objects on Earth that are just 10 inches(25cm)across.Peeringall the way from outer space, it can make out a smartphone held in your hand. It can tell what types of cars are traveling down a road. But it can't identify your face or read the cars' license plate numbers . . . at least not openly.According to some reports, this satellite and other US spy satellites have the technology to take even sharper images, with a resolution(分辨率)of up to around 4 inches(10cm). ButUS law forbids making these super-sharp pictures public, to prevent enemies from using them. But the idea that anybody might be able to spy on the entire Earth in such detail may seem horrible. Live, high-detail satellite mapping could possibly be used to monitor anybody at any time. Ray Purdy of University College London told CNN that he is concerned about what this could mean for privacy. Most satellites are commercially owned, so if you have money you can buy that imagery. “It means anyone can spy on anyone,” he said.At the same time, live, detailed maps of Earth's surface could be useful in amazing ways. Live maps of a disaster area could quickly discover people in need of rescue as well as the safest routes in or out. Satellite images are already helping catch illegal logging and fishing operations. Higher detail may make it possible to catch other criminals in the act. The images could also make it easier for farmers to watch over their crops.What do you think? Do you wish everyone could access high-detail live maps of Earth's surface?4. What does the underlined word in paragraph 2 mean?A. SeeingB. StandingC. WalkingD. Hearing5. Why does US law forbid making super-sharp pictures public?A. to protect the technology.B. for the sake of safety.C. to protect the environment.D. to threat other countries.6. Which of the following statements is true according to the text?A. This super-sharp map hasn't been put into market.B. Worldview-3 satellites orbits the Earth at 370 km away.C. Personal privacy is safely protected if you use the super-sharp map.D. The super-sharp map should be completely forbidden.7. How is this technology used in agriculture?A. It can help improve the production of crops.B. It can help kill pests.C. It can help farmer to watch over their crops from far away.D. It can help increase farm land.CItzhak Perlman was born in Tel Aviv, in whatwas thenPalestine, in 1945. Today he lives inNew York City. But his music has made him a citizen of the world.

They say he is able to communicate the joy he feels in playing, and the emotions that great music can deliver.Anyone who has attended a performance by Itzhak Perlman will tell you thatit is exciting to watch him play. His face changes as the music from his violin changes. He looks sad when the music seems sad. He smiles and closes his eyes when the music is light and happy.

When Jeffrey and his partner arrived at the scene, they found the young male face down on the ground. He had gone unconscious, making weak attempts to breathe. His wife stood beside him holding their small son in horror. They quickly rushed to calm the man to keep him under control and offer necessary first aid. After Jeffrey dropped the patient off at the neighboring hospital, he thought about the man and his family for a long time.Jeffrey thought he had experienced everything under the sun until one random visit to Office Max three years ago, where he met a man repeatedly walking back and forth while staring at him. As it turned out, the man was the patient he had saved 20 years earlier."You gave me 20 years more than I ever thought I'd have," the man said. He thanked Jeffrey repeatedly and told him he had someone he wanted him to meet. He stepped around the corner and reappeared with a 20-something-year-old man.

The writer of the letter was Mrs. Berna-dette Giandomenico, who once suffered from APL but was cured with all-trans-retinoic acid (ATRA)(全反式维甲酸), a treatment developed by Wang and his medical team.Working at Ruijin Hospital, Wang has been devoting his life to the treatment of leukemia. He received the country's highest honor in science and technology in 2010.Born in 1924 in Shanghai, Wang was inspired by a family friend's experience of pursuing a career in medicine as a child. His grandmother's death caused by typhoid (伤寒) further strengthened his resolve to fight against diseases and rescue patients. With outstanding academic performance, Wang became a doctor at Guangci Hospital, today's Ruijin Hospital.In 1978, a research paper from Israeli experts gave Wang inspiration on studying how leukemia cells could become normal. His research didn't progress as expected, though. In 1983, another research paper shed light on his study. As the paper suggested, after being treated with 13-cis-retinoic acid, white blood cells in patients with APL could become normal. Considering the difficulties and high cost of producing a drug made from 13-cis-retinoic acid, Wang's team decided to replace that ingredient with ATRA, and they finally verified itspositive effect after several months' experiments. In 1986, the drug was first adopted in treating a five-year-old patient. It turned out successful. After eight years of research, Wang's team eventually made the first breakthrough in the battle against APL.To make sure every APL patient could afford the medicine, Wang has not patented his research result to date. "One cannot be a real doctor if one does not have expertise in medicine," Wang said in an interview. "However, without a kind heart, a skilled doctor may cause harm to patients."Having worked in the field of hematopathology(血液病理学) for over 70 years, Wang has been well recognized for his remarkable contribution to saving lives.24.Why did Mrs. Giandomenico write a letter to Professor Wang?A. To ask for medical suggestions.B. To share her battle against APL.C. To express her appreciation.D. To update information about her treatment.25.What increased Wang’s determination to become a doctor?A. His grandmother’s death.B. His great academic achievement.C. The inspiration from foreign experts.D. The example of a family friend.26.What does the underlined word “verified” in Paragraph 4 probably mean?A. deniedB. assessedC. predictedD.confirmed27.What is the best title for the text?A. The application of ATRAB. A doctor with the human touchC. The Chinese cure for APL patientsD. A lifesaver with remarkable honorCThe seal feels perfectly safe lying on the Antarctic ice even if it is surrounded by a pod of killer whales. But within minutes it has been knocked into the water in a clever team tactic (战术) before being killed. These astonishing pictures show how the sea predators work together—and the technique provides meals for killer whales three out of every four timesthey use it, according to scientists.Research has also found that the mammals—around 26ft in length and weighing more than six tons—carefully kill the prey underwater,co-operating as they skin and dissect(解剖)the seals. Dr Robert Pitman,a marine scientist at the National Oceanic and Atmospheric Administration in California, took the shocking images of the pod going in for the kill. He said, “The killer whales were very good at knowing in advance if they were going to be able to wash a seal off a floe(大浮冰)and they were always successful in getting the seal into the water. A couple of times the seal was washed off but managed to escape in the confusion, but not very often. From killer whale studies elsewhere we expected this kind of social interaction but it was the canniness(精明)of their hunting tactics that blew us away.”Dr Pitman and his colleague Dr John Durban helped a BBC film crew capture their behaviour for the TV documentary series Frozen Planet, to be shown later this month. They spent weeks tracking and recording the hunting behaviour in the pack ice off the coast of the Antarctica Peninsula. The whales prefer Weddell seals, which can be up to 11 feet long, rather than the more aggressive crabeater and leopard seals. Dr Pitman told the Sunday Telegraph that the whales deal with seals who try to hide among the ice after being knocked into the sea by creating shock waves with their tails to knock them out into the open water.He said, “The whales also blew streams of bubbles under the seals apparently trying to get them into open water where they wouldn't have a chance against the waiting killer whales.”28. Which of the following is true about the killer whales' hunting tactic?A. They kill the whale before knocking it into water.B. They use the tactic three or four times before succeeding.C. They make astonishing shows to have other sea predators work together.D. They manage to earn their meals with the tactic in most cases.29. As is mentioned in the passage, Robert Pitman______________.A. worked as a reporter at BBCB. filmed Frozen Planet all by himselfC. followed and recorded the killer whales for weeksD. conducted studies on killer whales elsewhere in advance30. From Pitman's study we know that killer whales____________.A. use their skin to interactB. are normally 11 feet longC. often have seals run away in the open waterD. take advantage of bubbles when hunting31. What's the main idea of the passage?A. A TV documentary series on seals.B. The canny team tactics of killer whales.C. Dr Robert Pitman's latest study.D.The special living habits of killer whales.DIn ancient times, our ancestors relied on stars to guide them on a clear night. Today, we have navigational systems to help us find our way, with the latest being the Beidou Navigation Satellite System (BDS).The BDS is entirely built by Chinese engineers. With the launch of the last satellite from the Xichang Satellite Launch Center on June 23, the global network of 59 satellites has been completed. On July 31, Beidou started providing full-scale global services. It’s difficult to imagine the dramatic impact those satellites, orbiting (绕…运转) the Earth, have on our daily lives.When you unlock one of Hellobike’s bicycles, you are using the BDS. The popular bike-sharing company came out with two new bike models this year that are equipped with the positioning service. “The intelligent lock on each bike receives Beidou satellite signals and sends positioning information to the data center, which will help collect big data on the bikes and estimate users’ riding demands in advance according to the data,” Chu Yiqun, a manager of Hellobike told Xinhua News Agency. Users can also find shared bikes more accurately thanks to Beidou’s global positioning accuracy of 2.34 meters.However, the BDS doesn’t just work one way. As the country’s largest space-basedsystem and one of four global navigation networks, along with the United States’ GPS, Russia’s GLONASS and the European Union’s Galileo, Beidou adopts a unique two-way communication system, including its ability to receive messages sent by people from areas with poor communication signals. Obviously, this exclusive function isn’t designed for users to chat online. Instead, it plays a role when disasters occur and communications are blocked.After the Wenchuan earthquake in 2008, all ground-based communication facilities were interrupted. Though the first generation of Beidou could only send 120 characters in a single message at that time, communication between affected areas and rescue centers was successful. Now, Beidou’s messaging capacity has been increased to 1,200 Chinese characters in a single message. It is widely used in disaster alarms, automatic identification and information release.As Sun Jiadong, former chief designer of the BDS said: “The application of Beidou is merely limited by imagination.”32. What can we know about Beidou from the passage?A. It’s able to provide worldwide coverage for navigation.B. Its last satellite was launched in Xichang on July 31.C. It’s one of the five global navigation networks.D. It’s jointly developed by Chinese and foreign engineers.33. Why is Hellobike mentioned in paragraph 3?A. To present the benefits and limitations of the BDS.B. To highlight the high positioning accuracy of the BDS.C. To show how the BDS makes people’s daily lives easier.D. To explain the unique way in which the BDS works.34. What is the function of Beidou’s two-way communication system?A. To collect instant feedback sent by global users.B. To allow users to chat online more conveniently.C. To make communication more fun and efficient.D. To help people when communication signals are weak.35. What do Sun Jiadong’s words in the last paragraph imply?A. Beidou stimulates users’ imagination.B. Beidou may be more helpful than we know.C. Beidou is currently limited in application.D. Beidou needs to be further perfected.第二节(共5小题;每小题2.5分,满分12.5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。
