He joins other spider heroes to fight against bad people.D. He refuses to stop looking for his dog and tries to get it back.BA kid hero“If you could have any three things, what would you want?”Eleven-year-old Ruby Chitsey loves asking that question, but it's not a game she plays. She asks the seniors (老年人) at nursing homes in Arkansas where she lives. Even more amazing, she then sets out to make their wishes come true.Ruby has long been close to the elders. Her mother has worked in nursing homes for many years. Ruby often stays with her in summer and asks the seniors if they need anything.Last May, Ruby noticed an old lady named Pearl staring (凝视) out a window. She seemed sad. “What are you looking at?” Ruby asked. Pearl said she was watching her dog being led away by his new owner. Ruby asked around and discovered that the nursing home didn't allow the seniors to have dogs and Pearl couldn't afford to pay anyone to look after her dog. Ruby also heard many stories about Pearl's friends there and found that they were unable to afford life costs. That was when she decided to do something about it.She started by asking the seniors what three things they wanted most in the world. Her mother worried that people would ask for cars and other things that an 11-year-old wouldn’t be able to provide. Instead, they asked for chocolate, fries, and even just pants that fit properly.“I felt really upset,” Ruby says. “We left the nursing home that day and went straight to a store and bought as many things as we could.”Using their own money, Ruby and her mother helped about 100 people in three months. Then, they started asking for donations (捐款). The good people in Arkansas strongly supported them, so Ruby and her mother set up aGoFundMe page—Three Wishes for Ruby's Residents. After GoFundMe named Ruby a Kid Hero and spread her story internationally, Three Wishes raised more than $ 250, 000 in five months. One of Ruby's new goals is to set up a shared computer in one nursing home in each state.Ruby doesn't plan to stop there. “I consider kindness to be my hobby,” she says, “and I’m very good at it.”24. What did Ruby do for the seniors at nursing homes in Arkansas?A. She offered to look after their dogs.B. She strongly supported their hobbies.C. She helped make their wishes come true.D. She played their favourite games with them.25. Ruby decided to help the seniors when__________.A. she started to volunteer at nursing homesB. her mother asked her for help in summerC. people named her a Kid Hero on the InternetD. she learned of the stories of Pearl and her friends26. According to the passage, which word best describes Ruby?A. Naughty.B. Humorous.C. Caring.D. Cheerful.COld habits, especially bad ones, can be hard to break.People often make fun of New Year's resolutions (决心). However, resolutions present a big opportunity for self-improvement. Fortunately, social science has some ideas about how to start a good habit and stick to it.Gary Charness and Uri Gneezy, two scientists at the University of Chicago, did some research, where 120 students were asked to take part in an experiment about exercise habits, and each of them would get $175 in the end. The students were randomly assigned (随机分配) to three groups. The first group got the money for just giving researchers permission (允许) to record their gym attendance. The second group gave permission, but had to go to the gym at least once the next month. The final group gave permission and had to go to the gym eight times that month.Unsurprisingly, the group that had to make eight gym visits to get paid exercised more than the other two groups. After the payments stopped, these students kept going to the gym at higher rates (频率). They went to the gym about twice as often as the other two groups.In another study, researchers invited 151 students to work out in the gym, and randomly assigned 75 to a“temptation-bundling” group. As they exercised, they listened to the start of an attractive audio-novel (有声小说). At the end of their workout, students were told that if they wanted to hear what happened next in their book, they would have to come back to the gym. They could only listen to the audio-book while exercising. The other 76 students also completed the first workout but without any kind of temptation bundle.It turned out that the students in the temptation-bundling group visited the gym 27% more often than the control group over the next seven weeks. Sadly, the temptation-bundling trick fell apart over the Thanksgiving holiday when the gym was closed.The studies show that trying something new quite often for as little as a month can kick-start a lasting change in behavior. Moreover, “temptation-bundling” may also be a useful method for changing behavior, particularly when used together with other methods. Even if you cannot promise yourself to stick with something for long, there is a huge benefit in putting in a lot of energy for a few weeks. It may pay off for longer than you think. So, why not challenge yourself with next New Year's resolution?27. What can we learn from the two studies?A. The students got different payments according to their gym attendance.B. The temptation-bundling group loved audio-novels more than the other group.C. 27% of students in the temptation-bundling group exercised more often than before.D. The students who exercised more often at first were more likely to keep working out.28. The third paragraph is mainly about __________.A. how the research was performedB. what was found in the researchC. why the scientists did the researchD. who took part in the research29. The underlined word “temptation-bundling” in Paragraph 5 probably means __________.A. forming new habits by trying something you didn't like beforeB. connecting something you like with something you have to doC. improving your workout skills by listening to audio-booksD. pushing yourself by doing two tasks at the same time30. What is the writer's main purpose in writing this passage?A. To encourage people to go to the gym more often.B. To present a new way to do scientific research.C. To offer advice on how to develop a good habit.D. To stress the importance of New Year's resolutions.DTaking a gap year after high school is getting more popular among young adults each year. According to the American Gap Year Association (AGA), a gap year is often a year-long break taken between high school and college. AGA stresses that a gap year is a year on, rather than a year off, to oppose the belief that students are taking this time off as a vacation from schooling.Gap years offer an opportunity for experiential learning. They allow you to leave the classroom and learn new skills and ideas through doing something. You might find yourself in completely new situations that call for special problem-solving skills. Moreover, many students go through twelve years of schooling in the same place with the same group of people. By taking a gap year, they can step out of their comfort zone (区域) and into an entirely new culture. Just like gaining new experiences on a gap year, they can also meet new people of all different ages and walks of life. Finally, a gap year can also be a great way to get yourself recharged (重新充电). Instead of immediately jumping into the next four years of your education, you can take a break from the classroom and focus on your personal interests and passions. Many top universities encourage accepted students to take a gap year before starting college.However, before you get too excited about the idea of taking a gap year, you should also know about possible drawbacks. If you take a gap year, you could fall a year behind your peers (同伴). To catch up, you have to come up with a plan to graduate in three years. For the most part, studies show that students who take a gap year find themselves more driven when they arrive at college. However, you might find it difficult to return to an educational environment after taking a year away from the classroom.There is no set time-line for your education, and going straight from high school to college definitely isn't for everyone. For me personally, I still benefit from my gap year experience traveling in European countries. Cap years can take a number of forms, and they require a good deal of intention and planning. So if you have a will-thought-out plan for taking a gap year, then you should feel confident in your decision. Taking a meaningful gap year could be one of the best life experiences you ever have!31. According to the passage, by taking a gap year, students can __________.A. become more popular among their friendsB. catch with their peers at study in collegeC. build a stronger relationship between learning and doing.D. realize the importance of staying in their comfortable zone32. What can we learn from the passage?A. Students should be encouraged to have a time off for a vacation after high school.B. Colleges should require students to spend their gap year traveling in Europe.C. It's better to recharge yourself by going straight from high school to college.D. A gap year provides students with an opportunity for personal growth.33Which of the following would be the best title for the passage?A. Take a gap year onB Gap years: a perfect holidayC. The risk of taking a gap yearD. How to take a meaningful gap year四、阅读短文,根据短文内容回答问题。

our group． Unluc kily， Mrs． Bartlett， our teacher， didn't put me in the group with any of m y friends． Instead， I was with Mauro， who never spoke English， Juliette ， who always wore thick glasses and Rachel， who wore strange clothes．I had never talked to them． Oh， how badly I wanted to be with my friends!I was so sad that I walked up to Mrs． Bartlett． "I know what you want， Karina，" she gently patted me on my shoulder， "but your group needs a leader． I need you to help them get a passing grade on this project． Only you can m ake it．"I was shocked．"Will you help them？" she asked．"Yes，" I replied． I couldn't believe it came out of my mouth， but it did．I bravely walked to my group and started our project． We had different t asks according to our interests． Gradually， 1 felt myself enjoying their co mpany． I found out Mauro was struggling with English．Behind Juliette's thi ck glasses were her sparkling eyes．Rachel was so creative that she wantedto be a fashion designer． I realized that they were not strange；they were just people that no one cared enough for-except Mrs． Bartlett．Her thoughtfulness brought out the best in the four of us．I learned something that week． I was given a chance to see other peopl e in a new light． I learned that who weare is more important than what we are or seem to be．Mrs． Bartlett gave us an A on that project， butthought we should have handed it right back， for she was the one who truly deserved it．（1）Karina badly wanted to be with her friends because she thought____．A． her friends took great interest in historyB． her group mates

Mrs． Bartlett is______．A． thoughtfulB． creativeC． honestD． strict28． A Johns Hopkins University researcher， Melville J． Wohlgemuth， noticed that the hats he worked with turned their heads to the side when hu nting． "It's a lovely behavior， and I was curious about the purpose，" he said． "I wanted to know when bats were doing this and why． It seeme d to happen as hats were targeting prey（瞄准猎物）， and that turned out to he the case．"Wohigemuth's team found that a bat's head and ear movements went with the animal's sonarvocalizations（声纳发声）to help it hunt． The findings show how movements can strengthen signals u sed by senses like sight and hearing-not just in bats， but in dogs and cats ， and even in humans．Bats' use of echo-location（回声定位）to find， locate and catch prey is well documented．But the lead author Woh lgemuth and his team are the first to show how the mysterious head and ear movements influence the hunt．The researchers used a novel method to study the head and ear moveme nts of the big brown bat，a common bat species． First， researchers trained the bat to sit on a platfo rm while tracking moving prey．After that， the researchers fixed markers to the top of the bat's head and both ears．The markers allowed the team to m easure the head and ear positions as the bat tracked the prey moving in vari ous directions．They found the head movements took place when the prey changed direct ion or moved unpredictably．The ear movements happened as the prey grew closer， which helped the bat hear the echoes it used to track and catch the prey． Most notably， these head and ear movements went with the bat's v ocalizations，allowing the animal to locate where the prey exactly was．Co-author Cynthia F． Moss said other similar studies missed the importa nce of head and ear movements， because laboratories usually observed the subject with a fixed head position． That's not how animals operate in the real world， when their heads are free to move．Moss compared the bat's head and ear movements to those of other spec ies that use active sensing to process important information．"By studying th ese movements，" she said，"we as humans can get insight into how movements help animals sense their environment．"（1）The research of Wohlgemuth and his team is the first to prove that____．A． head and ear movements help bats locate the preyB． animals send signals to help them hunt more quicklyC． humans learn to hunt by copying animals' movementsD． sonar vocalizations can work for both animals and humans（2）The fourth paragraph is mainly about_____．A． how the bat uses head and ear movements to track moving preyB． how the researchers studied the head and ear movements of the bat C． how the bat is trained to track the prey by moving its head and ears D． how the researchers measured the moving hat's head and ear positions （3）Which is the best title for the passage？______A． Bats： A Master of Night HuntingB． Bats： A Model of Fast MovementsC． Bats： An Expert of Exact LocationD． Bats： An Example of Mysterious Animals29．Our brains believe information automatically（自动地）-even if it's false-because we can learn efficiently this way． "We're learning false information not because we're poor learners or not working hard，" says David Rapp， a psychology and education professor at Northwestern University． "In many cases， it's a useful skill for us to accept what people tell us， because often what people tell us is true．"When we hear new information， those fresh facts don't cover what we k new before． We'll draw on old or new information when the situation comesup．． Short-term memories are easier for our brains to access than facts we heard longer ago， because they're fresher in our minds-even if they're wrong． Since we have to think back further to remember old infor mation， we will often ignore it in favour of new inaccurate（不准确的）information． New information is what we're currently thinking about or has b een recently presented to us， while the old one isn't as readily available．We also buy into the facts that seem more reasonable． Often， this mea ns they fit better with what we want to believe， which can explain why peopl e quote different facts in political debates． Both candidates said something that was objectively true or not， but people would go with what they hope to be true．Things get even trickier when truth and falsehood coexist in the informati on．For instance，our brains aren't sure whether to believe the descriptions of London in Harry Potter．"Don't look for that train station to Hogwarts， but there might be str eets mentioned that are real，" says Dr．Rapp．In fact，our brains can keep track of what's true or false by mentally tagging（标记）facts as either true or false，but sorting all that information takes time． In many cases， we are unlikely to think critically to get information， especially when we are reading for ple asure．However， it's worth putting in the extra effort to have a second thought about the information that seems doubtful． "With the ease that we can look things up on the Internet，" says Dr． Rapp， "there's no reason not to．" "Seek out reliable sources，" he adds．（1）The missing sentence in Paragraph 2 might be "____ "．A． We always find the information updating fast nowadaysB． Oftentimes， we use the information we heard most recentlyC． From time to time， we fail to remember unimportant thingsD． We hardly see old information that is different from the truth（2）The underlined phrase "buy into" in Paragraph 3 can be replaced by___．A． believe inB． learn fromC． come up withD． care about（3）Why does the writer mention Harry Potter in Paragraph 4____A． To prove people are unable to think critically when reading．B． To show the information we get can be a mix of true and false．C． To warn readers of the negative influence， of false information．D． To explain how individual facts are mentally tagged as true or false．（4）What can we learn from the passage？_______A． Our brains can do very little with false information．B． Short-term memories can cover long-term memories．C． Dr． Rapp calls on people not to depend on the Internet．D． People need to double-check the information they question．七、阅读短文，根据短文内容回答问题．（共10分，每小题10分）30．It is reported that tea has helped poor farmers in Yunnan find a way out of poverty（贫穷）thanks to the efforts of a man， who had a chance to come across some loca l farmers there．Ren Huaican was suffering mass mouth takers（溃疡）when he first visited the Jingmai Mountain in Pu'er city in the spring of 2006． However， after picking off several leaves from the old tea trees and che wing them， he felt amazed to find the pain was gone the next morning．The fact that the green leaves worked magic for him made Ren begin to show gr eat interest in the tea from Yunnan．During his search for tea production bases in the mountains across Yunn an， he found that the local tea business was scattered（分散的）and most of the tea farmers were living in extreme poverty． Ren realized w hat led to the tea industry problem was not only the underdeveloped tea mar ket， but also the poverty of the local tea farmers． So he made up his mind to change things

They have been for both kinds of weather for more than 3,000 years. You might say that umbrellas are dripping with history.Early Egyptian rulers used them in ceremonies. Leaders of old Japan walked under red umbrellas. They were a sign of power. The kings of Burma（缅甸）rode on white elephants under white umbrellas. People in Greece and Rome also used umbrellas long ago. The umbrellas of early times were used in warm lands as protection against the sun.By the 1600s umbrellas had appeared in northern Europe. In these countries they were used on rainy days,too. The umbrellas were thought to be big and clumsy（笨重的）. They were used only by people who didn't have carriages.By the 1700s umbrellas had jewels and fancy handles made of rare wood. Some umbrellas had hollow（空的）handles. Perfume, knives, and even pens and paper were kept in these handles.Umbrellas were improved in the 1800s. Before that time most were made with whale bones. They weighed 10 pounds! By 1826, their weight was down to 1.5 pounds. Steel frames（框架）were first used in 1852. Covers for these umbrellas were made of waxed silk or oiled paper.Today's umbrellas are very light. Some people think they turn inside out too easily, but modern umbrellas do have some good points. For example, they fold up into smaller packages. Some have plastic windows in them so people can see where they're walking. When the rain comes down, people can pop open their umbrellas quickly and be on their way.The umbrella were popular in northern Europe by the 1600s.B.C.D.Some people in England of 1720 kept knives in their umbrella handles.Umbrellas were improved in the 1700s and iron frames were first used.Modern umbrellas are big and clumsy, but can fold up into smaller packages.15.（1）The word queasy in the title means .A.sick to your stomachB.sad and worriedC.short of breathD.tired and sleepy（2）The best thing we can do t keep fish healthy is to .A.B.CTHAT QUEASY FEELINGRemember the last time you were sick? Maybe you didn't feel like eating because you had a stomach ache.And your mom or dad told you that you had to eat to keep up your strength. So you ate, even though you didn't feel like it. When fish get sick, they often don't feel like eating, either. The longer they go without eating, the sicker they get. Sometimes, the fish die.WILD FISH DON'T HAVE DCTORSFish that live in hatcheries（孵卵所）are constantly watched to make sure they don't get sick. But sometimes they get sick anyway. Then, the people who care for them medicine to help them get better. But fish that live in rivers and lakes don't have anyone watching over them all the time. If they get sick, people might not find out about it for a long time --- too late to keep a disease from spreading. So the best thing we can do for fish that live in our rivers and lakes is to help them NOT get sick in the first place.PRESCRIPTION: SQUEAKY CLEANThe most important thing we can do is to make sure fish have a clean, healthy place to live. We have to protect our rivers and lakes by preventing pollution and caring for the environment where these fish live,breathe, and eat. The lake or river in which fish live is where they find food and protection, and its waters carry oxygen（氧气）that they breathe through their gills（鳃）. Usually, if we can keep the habitat healthy, we can keep the fish healthy.THIS LITTLE FISH STAYED HOMEFish have ways of fighting off germs（细菌）they've become used to. Their bodied have learned to protect themselves from such germs. This protection is called immunity （免疫力）. You probably have immunity to certain germs, too --- chicken pox, for example. Once you've had it, you never get it again. But, like humans, fish often cannot fight off new germs. That's why fish should NOT be moved from one stream or lake to another except by biologists who have made sure the fish do not have germs. Next time you look into your favorite river or lake, think about the fish that live there. And always do all you can to help keep the fish and the water healthy.get fish back to hatcheries and watched overremove dirty oxygen from rivers and lakesC.D.（3）This article is mostly telling about .A.B.C.D.move fish from one stream or lake to anotherkeep rivers and lakes clean and free of pollutionhow hatcheries help keep fish healthywhy sick fish don't feel like eatingwhy fish become used to some germshow people can keep fish healthy16.（1） Examples of service learning may NOT include .A.teaching a studentB.working in a soup kitchenC.cleaning up a polluted riverD.writing a report afterward（2）Supporters believes service learning is mainly for .A.B.C.DThe requirements for high school graduation have just changed in my community（社区）. As a result, all students must complete sixty hours of service learning, or they cannot finish the education in high school.Service learning is a school subject that also helps the community. Examples of service learning include cleaning up a polluted river, working in a soup kitchen, or teaching a student. During a service experience, students must keep a diary and then write a report about what they have learned.Supporters state that there are many benefits of service learning. Perhaps most importantly, students are forced to think beyond their own interests and realized the needs of others. Students are also able to learn real-life skills that include responsibility, problem-solving, and working as part of a team. Finally, students can think about possible careers（职业）through service learning. For example, if a student wonders what teaching is like,he or she can choose to work in an elementary school classroom a few afternoons each month.While there are many benefits, people who disagree with service learning point out problems with the new requirement. First, they hold their opinion that the main reason students go to school is to learn key subjects and skills. Because service learning takes too much time, students spend less time studying the key subjects.Second, they believe that forcing students to work without pay goes against the law. By requiring service, the school takes away a person's freedom to choose.In my opinion, service learning is a great way to contribute to the community,learn new skills, and think about different careers. However, I don't believe you should force people to help others —the wish to help must come from the heart. I think the best way is one that gives students choices: a student should be able to choose sixty hours of self-study or sixty hours of service.Choice encourages both freedom and responsibility, and as young adults, we must learn to deal with both wisely.teaching students real-life skillspractising students to work as a teamforcing students know what others need阅读与表达D.（3）People who disagree with service learning think that .A.B.C.D.（4）What's the writer's opinion on service learning?A.B.C.D.helping students think about their possible careersstudents must spend more time on key subjectsservice learning is meaningless to studentsthere are more disadvantages than benefitsforcing students to work goes against the lawStudents should be more responsible in service learning.Service learning is likely to be less important than self-study.Service learning should be encouraged in more high schools.Students should be free to choose between self-study and service learning.17.（1）How many pieces of advice are given in the passage?（2）Is everyone special?（3）What kind of person is popular?（4）What will happen if we follow all the advice in the passage?When you step into a new environment, you must have a strong wish to fit in.
