Klingbeil, 18, had to go through months of chemotherapy (化疗) and radiation treatments after her diagnosis, which left her too weak to compete.The COVID-19 left Klingbeil away from her teammates as school went virtual and track meets were canceled. She faced another challenge recently when doctors discovered her cancer had returned, leading to more chemotherapy.Despite the challenges, Klingbeil’s track coach, Rob Cloutier, reached out to her to see if she would like to join her teammates in a tradition in which seniors run the 4x100 race at the last home track meet of the season. “I told her to run the anchor leg, which is the final leg of the race,” said Cloutier. “I wanted her to be able to do it one last time.”Hearing the news, Klingbeil was excited. Meanwhile, Klingbeil was just starting to walk again after using a wheelchair due to complications (并发症) from chemotherapy, but she was committed to running her high school track one last time with her teammates.Klingbeil had a chemotherapy treatment on the day of the last track meet, May 24, and then put on her team uniform for the first time in over a year. When it washer turn, her three race teammates came to her side and walked the track with her. The entire Shen High School track team also walked along with Klingbeil from the field and then rushed and cheered for her when she crossed the finish line. “That was a great surprise,” Klingbeil said, “I feel accomplished because crossing the line was a perfect end of my high school track career.”Cloutier said he had watched Klingbeil go through her cancer battle with that same level of determination, saying “She’s worked through this challenge in her life without a single complaint and with a smile on her face. Everyone who has witnessed her can learn a little bit from that.”4.Why couldn’t Klingbeil continue her track career?A.She hurt her muscle badly. B.She must focus on her study.C.She had little time for running. D.She suffered from a severe disease. 5.What did Klingbeil’s coach do for her track career?A.He made a wheelchair for her.

D.He organized her teammates to help her.6.What can we know about Klingbeil’s last track meet?A.She had a treatment after it. B.She didn’t make it to the finish line. C.She had a sense of achievement after it. D.She walked the track with all her teammates.7.Which of the following can best describe Klingbeil?A.Caring and optimistic. B.Determined and positive. C.Responsible and sensitive. D.Powerful and independent.For many animals in the ocean, crabs are food. That’s a problem for crabs. How can they stay off the dinner menu? One type of crab, known as the decorator crab, has found a clever solution. It “decorates” itself. Decorator crabs use seaweed to change their appearances so that predators (捕食者) will not recognize them.More than 100 species of decorator crabs are found all over the world. One species, commonly called the longnose spider crab, takes decorating to a whole new level.The ocean floor was covered in seaweed, but these crabs wouldn’t use just any kind they found. “They were very, very picky, and things they pick were quite uncommon.”says Dr. Stachowicz of the University California.He noticed that longnose spider crabs would grab a piece of seaweed and take a little bite. Sometimes they would just eat the seaweed. Other times, they would reach back and attach the piece to the small hairs on their back. These crabs were choosing to decorate themselves with seaweed that has a peppery-tasting (胡椒味) chemical in it. Most fish find this chemical unappetizing. “If the crabs just decorated to look like the background, they would be giving their predators a little side salad with the main course.” says Dr. Stachowicz. But by carefully choosing the peppery seaweed, these decorator crabs look less tasty and predators avoid them.Once a longnose spider crab has put together a good suit to protect itself, it is set for a while. The seaweed continues to grow even while it’s stuck to the crab’s back. When a crab sheds (去除) its old shell, it has to redecorate, often using seaweed from its old shell. Basically, the crab recycles.8.How do the longnose spider crabs differ from other decorator crabs?A.They like eating seaweed.B.They pick seaweed carefully.C.They have small hairs on their back.D.They use any seaweed to decorate themselves.9.What does the underlined word “unappetizing” in paragraph 3 probably mean? A.Unattractive. B.Unusual. C.Unhealthy. D.Unimportant. 10.What do we know about the longnose spider crabs from the text?A.They shed their old shells regularly.B.The decoration on their shells lasts forever.C.They prefer the seaweed that fish usually avoid.D.They never redecorate themselves with new seaweed.11.Which of the following can be the best title for the text?A.Survival Tips for the Crabs B.A Problem for CrabsC.Ways to Decorate the Crabs D.A Crab’s Clever ClothesCarleen Hutchins finished building her first stringed instrument (弦乐器) in 1949, when she was 38. She is remembered as an excellent luthier. A luthier is a person who makes stringed instruments, such as violins and guitars.Hutchins was a primary school science teacher. She took up the viola (中提琴) at 36. But she wasn’t satisfied with the viola she bought. Since she was a skilled woodworker, she decided to build one herself.For more than 50 years, she carved (雕刻) stringed instruments. Hutchins worked from her home — often in her kitchen. She used a scientific method to carve them. Over the years, she made around 500 instruments. Her method is still used. It helps luthiers carve high-quality stringed instruments.Hutchins also created a family of eight violins known as the violin octet. They change in size and tone (音调). “It’s how the instrument is carved that makes it a violin,” Joe McNalley says. He is the founder of the Hutchins Consort, a group that plays the octet.The four instruments in the string family are violin, viola, cello, and bass. They cannot play the lowest or highest notes of the piano. They play the notes in between. Hutchins created a family of eight violins that play all the notes a piano plays.D.Quincy Whitney has written a book about Hutchins. “For centuries, musicians had talked about creating a family of violins that had a total string sound as wide as a piano,” she said.Hutchins was an artist and a scientist. A big part of her dream was to create top-quality instruments that were affordable. “Her story is about how one person can not only make a difference,” says Whitney, “but can change a whole world.”12.Why did Hutchins start to make stringed instruments?A.She hoped to create a better viola.B.She was not satisfied with her career.C.She expected to be a skilled woodworker.D.She wanted to teach her students about music.13.What do we know about Hutchins?A.She headed the Hutchins Consort.B.She is very good at playing the octet.C.She learned a simple method to make instruments.D.She is a pioneer in the design of stringed instruments.14.Different from the traditional violin family, the violin octet _____.A.is easier to make B.has the same sizeC.produces richer sounds D.is less enjoyed by musicians 15.What is Whitney’s attitude to Hutchins?A.Respectful. B.Concerned.C.Doubtful. D.Worried.二、七选五You’re out on a hike, snacking on an apple,a banana, or a handful of nuts. When you’re finished, all that’s left is a core, a peel, perhaps a shell.“It’s natural,”you tell yourself, throwing it away carelessly. After all,food waste isanimals, or even put other people at risk.Food waste doesn’t decompose as fast as you think17 .But fewer people are aware that food waste like orange and banana peels can take up to two years to break down in the wild. And even if those food waste finally biodegrade, they can lead to many serious problems.Animals are attracted to food waste“Animals have a super advanced sense of smell compared to us,”says Jeff Marion, a biologist. All human food can attract animals. This can cause“attraction behavior”, which refers to human actions that cause animals to overcome their natural caution of people. 18Human food can make animals sickAnimals becoming attracted to and subsequently used to human food can lead to far-reaching health issues in animals. Food waste by the roadside may cause animals deaths because wildlife attracted to that food can be hit by a vehicle. 19 .Mostfood waste is never animals’ normal diet, which can be deadly.20To prevent any of these unwelcome effects, the best thing to do is to store and deal with food waste well. Don’t throw it about. Don’t burn it,as it is more difficult to burn. And if you pass other food waste on the trail or in the park, pick it up, even if it’s not yours.A.Most people know food waste is biodegradableB.Play your part by keeping your food to yourselfC.Make sure you won’t throw food waste randomlyD.The food itself can also make animals sick and even kill themE.Animals can’t get to know the harm that human food containsF.This sort of attraction behavior can quickly become dangerousG.But food waste can cause a lot more damage than you may think三、完形填空The parents who adopted (收养) Bruce Hollywood encouraged him to find histhe restaurant his birth mother had owned for decades in Japan and found out she had named it “Bruce”.Bruce couldn’t 34 the moving words he heard when seeing his birth mother for the first time in 45 years. He learned that love could always stand the test of 35 and distance.21.A.interested B.worried C.surprised D.afraid 22.A.working B.settling C.talking D.arguing 23.A.looking for B.dealing with C.waiting for D.caring about 24.A.suitable B.unique C.useful D.familiar25.A.on time B.by chance C.on purpose D.by mistake 26.A.conversation B.meeting C.gathering D.discussion 27.A.boring B.relaxing C.disappointing D.inspiring 28.A.forced B.warned C.allowed D.advised 29.A.checked B.ignored C.lost D.collected 30.A.Since B.Though C.Unless D.When31.A.friend B.translator C.teacher D.guide32.A.joy B.fear C.anxiety D.anger33.A.left B.designed C.visited D.ran34.A.forget B.believe C.remember D.explain 35.A.money B.time C.class D.energy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。

I then realized she had no arms or legs, just a head, neck and upper body. She was wearing a little white dress with red dots. As the couple wheeled her up to me, I was looking down at the register. I turned my head toward the girl and gave her a wink (眨眼). As I took the money from her grandparents, I looked back at the girl, who was giving me the cutest (漂亮的,机灵的), largest smile I have ever seen.All of a sudden her handicap was gone and all I saw was this beautiful girl, whose smile just melted me and almost instantly gave me a completely new sense of what life is all about.

AAndy never wanted to go to bed on time. His parents had explained to him how important it was to go to bed early and get a good rest. But Andy paid no attention to them, and they didn't know what to do until one weekend when they were visiting Andy's grandparents.Grandpa Peter heard all about it and said, "This sounds like a job for Tubby." So Andy's parents loaded the cat onto the car and returned home.That night, at bedtime, the same problem happened. Andy didn't want to go to bed, and even though his parents waited a while to see if Tubby would solve the problem, nothing happened.Hours later, Andy finally decided to go to bed. But what a surprise when he entered his bedroom! Tubby was in his bed, totally sprawling out, pot-belly in the air, and snoring like an express train.Andy tried to move the cat, but there was no way of moving him an inch. That night he hardly slept, lying on one tiny corner of his bed.The next day the same thing happened, even though Andy was much more tired from not having slept well. When the third day arrived, he had understood that if he wanted to sleep in his bed, he would have to get into it before Tubby did. That night, when his parents only started to mention the topic of bedtime, Andy rushed upstairs and dived into bed. His parents could not believe it. They knew nothing about Tubby in the bed, nor did they understand why Andy went to bed on time without complaint. They were so happy about this that they stayed up quite late, celebrating.21.

The passage was mainly written to_______.A. explain some websites for parentsB. compare some educational websitesC. introduce different parts of a websiteD. offer some websites that may help studentsCAre you willing to work for a robot boss? Sorry if your answer is "no", because it will be common in the near future, according to the researchers from the Oxford.A third of British jobs are at "high risk" of being replaced by robots in the next 20 years, the research by Deloitte, the Oxford Martin School and the University of Oxford found.Wired magazine went further. "It may be hard to believe, but before the end of this century, 70 percent of today's jobs will be replaced by automation(自动化技术)," said the magazine in 2012.Of course, people being replaced by robots is not recent news. Robots have been taking over labor work in factories and on farms for some time, lifting heavy boxes and picking fruit and vegetables. Next, cleaning jobs in offices and schools will be taken over by late-night robots, starting with easy-to-do floors and windows and eventually moving to toilets, Wired predicted.But that's just the beginning. Even white-collar jobs are not safe. Any jobs dealing with sales and services or lots of paperwork could be taken over by robots in the future. For example, in the UK, library assistants have decreased by 48 percent since 2001, sales-related jobs have fallen by 40 percent, and travel agents by 44 percent, the Daily Mail reported.But that doesn't mean that human beings will have nothing to do in the future. Instead, we need to update our skills. Digital know-how, management and creativity will be in greater need in the future, said British Consulting Company Deloitte.29. The underlined sentence means _______.A. a third of British jobs are dangerousB. a third of British jobs are well-paidC. British people may replace a third of robots' jobsD. British people may lose a third of their jobs30. In the fifth paragraph, the writer's opinion is made believable mainly by_______.A. telling storiesB. using figuresC. making comparisonsD. asking questions31. From the passage, we know the following jobs are disappearing except _______.A. workers in factories and farmsB. library assistantsC. salesmenD. architectDThe bed should be used as a place for sleep, but more and more people like to read an iPad a lot in bed before they go to sleep.Charles Czeisler, a professor at Harvard Medical School, and his coworkers got a small group of people for an experiment. For five days in a row, these people read either a paper book or an iPad for four hours before sleep. Their sleep patterns were monitored all night. Before and after each trial period, they took hourly blood tests to paint a day-long picture of just how much melatonin(褪黑激素) was in their blood at any time.When the people read the iPad as compared to the paper books, they felt less sleepy at night and less active the following morning. People also took longer to fall asleep on the iPad nights, and the blood tests showed that their melatonin secretion(分泌) was delayed by an hour and a half.The researchers concluded that because of the rise of e-readers and the widespread use ofe-things among children and teenagers, more research into the "long-term influence of thesee-things on health and safety is urgently needed." Czeisler and coworkers went on, in the research paper, to point out that reading an iPad in bed may increase cancer risk.However, software has been developed that can reduce some of the blue light from the screens of phones and computers, and there are also glasses that are made to reduce short wavelengths. While they seem like a logic solution for the nighttime tech users, it needs more research.32. In Charles Czeisler's experiment, the group of people were asked to_______.A. sit in a row and receive the strict testsB. have their sleep patterns observed all nightC. read a paper book and an iPad before sleepD. have their blood tested per hour during the trial33. The third paragraph tells us the iPad readers were likely to_______.A. feel less sleepy and tired in the dayB. fall asleep more easily after readingC. become less energetic the next morningD. have a lot more melatonin secretion34. The special software recently developed can _______.A. reduce the blue light from the screens completelyB. help prevent eyes being harmed by short wavelengthsC. reduce the harm caused by doing nighttime e-readingD. be used in all the e-things widely and safely35. Which of the following can be the best title for the text?A. No e-reading in bed before sleepB. New software for night e-readersC. Wrong things to do before bedtimeD.
