He played as a linebacker(中后卫球员). Sadly, he often found himself at the bottom of the piles, where everyone would jump onto each other at the end of every play. Bob's mom realized it was hard for her son to hear her cheering. She hadto find a solution, but couldn't find one.Then one day the coach from the school team asked him if he wanted to join the team. Bob wasecstatic, because he was only a ninth grader. His mom was also excited, since she loved football and especially loved watching her son play. She kept considering a way for him to hear her. A cowbell! That was it. Now from the bottom of the piles Bob would hear his mom shaking her cowbell crazily, knowing she was there for him.Bob's team finally made it to the state championship game. What exciting time to play at Busch Stadium under the lights! This experience made Bob appreciate all the years that his mom had sacrificed everything to get him to practice every day, to wash his uniforms, and to never miss a game. He had to do something.On the night of the state championship game, the loudspeakers introduced Bob, and as he walked onto the field his mom shook the cowbell, hard. However, it didn’t sound right. She looked its inside, and found a note saying,”Thank you, Mom.” Bob had left her a note expressing his appreciation for always being with him, filling her heart with warmth.Finally Burroughs claimed the title of State Champion. While others were cheering and admiring the state championship cup, Bob' s mom clutched(紧握) her cowbell happily.Years later, Bob’s mom died.

A tiger was recently seen on the Siner Russian border（边界），but there is no evidence to suggest this is the same tiger or that it had lost its way from Russia.Wherever it may have come from, cross-border protection of endangered species is a problem. According to Ma Jianzhang, a senior wild animal researcher in China, tigers know no borders, which have been built to stop humans from illegally crossing over. However, these borders also stop the free movement of tigers, thus preventing their breeding（繁殖）and exchange of genes.The Sino-Russian border alsocomes in the way ofprotecting tigers in the region. Data show about 500 to 550 Siberian tigers, or over 90 percent of the species, live in the wild in Russia; 27 live in the wild in China, and 50 inthe border region. Sometimes tigers lose their way across the border and that is hindering（妨碍）efforts to stop illegal hunting and protecting them.Fortunately, both China and Russia have realized this problem and are working toward solving it. As early as 2010, the two countries established a cross-border protection network aimed at strengthening communication on protecting tigers in the northeast. The countries have also held anti-poaching（反偷猎）activities together. In 2019, two national parks from the two countries signed a three-year deal to share research data on tigers, greatly improving the living conditions of Siberian tigers in the wild.However, much more needs to be done to protect the species. It is necessary to combine the tiger protection areas in the two countries. That will require greater efforts from both sides and some difficulties might remain even then. Fortunately, both countries have been taking effective measures to provide the endangered species a better home.8. What's the original purpose of setting up the Sino-Russian borders?A. To ban people from illegal crossings.B. To help protect tigers in the region.C. To protect tigers from losing their way.D. To stop tigers' breeding and exchange of genes.9. What does the underlined phrase “comes in the way of” probably mean?A. keeps from.B. is on the way toC. is aimed atD. keeps up10. What is the focus of Paragraph 4 ?A. Recent studies and researches on tigers.B. Joint efforts by China and Russia to protect tigers.C. The possible effects of establishing a networkD. Reasons for improving the living conditions of tigers.11. What's the author's purpose in writing the text?A. To inform the possible dangers of tiger protection.B. To cover the news about a missing tiger on the border.C. To put forward suggestions on finding the missing tiger.D. To report the problems and measures of cross-border tiger protection.DTwo young brothers fromMalden.Massachusettswere in the spotlight Thursday after being named “heroes" by a national organization that recognizes young people doing great things.

I was born two weeks late. When I finally entered the world I weighed 11 pounds 10 ounces and was 24 inches long. When my mom told my grandmother my measurements, she asked in amazement, "Are you okay?!"I was healthy, but very shy as a child and into my teens. I'm from a small town, and I grew up and graduated with the same 50 people. I started playing basketball in third grade every Saturday, but I didn't have any control over my awkward body. (I didn't even score a point in a game until many years later.) I was 5-foot-10 in fourth grade. I had a small group of friends in elementary school, but sometimes the boys picked on me, calling me a bean pole or the Jolly Green Giant. I still remember my embarrassment when they laughed at me, and how badly I wanted to be invisible.In high school I got more involved in sports, but I spent most days in the art room. By this time everyone at my school was used to my height (by ninth grade I was 6-foot-3), but if I went out of town people would stare at me and comment about my appearance.I was forced into the spotlight wherever I went.With high school came more confidence. I had success in school, the arts and sports. I played basketball, but my true passion was track and field. During my senior year I was the conference champion in high jump and the 400-meter run. The friendships I gained through my involvement in high school boosted my confidence and helped me develop a sense of humor. Now when a stranger told me I was tall I would smile and nod or, if I was feeling determined, I would pretend to feel shocked and thank them for telling me. I had no idea!Still, society keeps me aware of my status as something rare. And even though people tell me I'm beautiful and I should be a model, there are times when I would trade in my long legs for a small frame and tiny feet. I often wish people weren't so rude. I'm a minority only in the sense of height. I like to think that those who have insulted me didn't intend to. I do believe that most people are basically good, but they can be insensitive.4. What can be inferred from Para.1?A. The writer's height has something to do with her late birth.B. Grandmother was unwilling to have the writer as her grandchild.C. The writer failed to have a successful life because of her unusual height.D. The writer was heavier and bigger compared with other babies when she was born.5. By saying 'I was forced into the spotlight', the author probably means that she ________.A.was criticized by othersB. caught public attentionC. was threatenedD. felt inferior6. Which of the following statements is NOT mentioned as the writer's experiences in high school?A. She quit playing basketball and joined the track and field team.B. She no longer felt upset when facing her height problem.C. She had a passion for some sports events.D. She built up more confidence.7. What does the last sentence imply?A. People enjoy making fun of others.B. People are bad andcannot be trusted.C. People tend to bully those who are weaker.D. People sometimes care little about how others feel.CIn order to help discover spoilage and reduce food waste for supermarkets and consumers, researchers have developed new low-cost, smart phone-linked, eco-friendly spoilage sensors for meat and fish packaging.One in threeUKconsumers throw away food just because it reaches the use-by date, but 60% of the £12.5 billion-worth of food we throw away each year is safe to eat.The researchers, whose findings were published in ACS Sensors, say the sensors could also eventually replace the use-by date—a widely used indicator of being fresh and eatable.The sensors cost two US cents each to make. Known as “paper-based electrical gas sensors (PEGS)”, they detect spoilage gases like ammonia (a poisonous gas with a strong unpleasant smell) in meat and fish products. The information provided by the electronic nose is received by a smart phone, and then you can know whether the food is fresh and safe to eat.The Imperial College London researchers who developed PEGS made the sensors by printing carbon electrodes onto a special type of paper. The materials are eco-friendly and harmless, so they don’t damage the environment and are safe to use in food packaging. The sensors, combined with a tiny electronic system, then inform nearby mobile devices, which identify and understand the data about spoilage gases.Lead author Dr Firat Guder of Imperial’s Department of Bioengineering, said, “Although they’re designed tokeep us safe, use-by dates can lead to eatable food being thrown away. They don’t always reflect its actual freshness. In fact, people often get sick from food-borne diseases due to poor storage, even when an item is within its use-by date.”“These sensors are cheap enough so we hope to see supermarkets using them within three years. Our goal is to use PEGS in food packaging to reduce unnecessary food waste.”The authors hope that PEGS could have applications beyond food processing, like sensing chemicals in agriculture, air quality, and detecting disease markers in breath like those involved in kidney disease.8. What is the function of PEGS according to the text?A. To improve the taste of foods.B. To improve the service of stores.C. To help supermarkets store foods.D. To help people test food freshness.9. What role does the smartphone play while PEGS are functioning?A. It acts as an electronic nose.B. It reads the data collected by PEGS.C. It helps print the gas sensors onto paper.D. It discovers the spoilage gases from foods.10. What does Dr. Firat Guder say about use-by dates?A. They are not completely reliable.B. They can help reduce food waste.C. They are based on scientific research.D. They are not accepted by the consumers.11. What does the author mainly talk about in the text?A. The process of researching spoilage sensors.B. A new technology in packaging to reduce food waste.C. The application of spoilage sensors beyond food processing.D. The influence of use-by dates on supermarkets and consumers.DWhat a day! I started at my new school this morning and had the best time. I made lots of new friends and really liked my teachers. I was nervous the night before, but I had no reason to be. Everyone was so friendly and polite. They made me feel at ease. It was like I'd been at the school for a hundred years!The day started very early at 7:00 am. I had my breakfast downstairs with my mom. She could tell that I wasvery nervous. Mom kept asking me what was wrong. She told me I had nothing to worry about and that everyone was going to love me. If they didn't love me, Mom said to send them her way for a good talking to. I couldn't stop laughing.My mom dropped me off at the school gates about five minutes before the bell. A little blonde girl got dropped off at the same time and started waving at me. She ran over and told me her name was Abigail. She was very nice and we became close straight away. We spent all morning together and began to talk to another girl called Stacey. The three of us sat together in class all day and we even made our way home together! It went so quickly. Our teacher told us that tomorrow we would really start learning and developing new skills.I cannot wait until tomorrow and feel as though I am really going to enjoy my time at my new school. I only hope that my new friends feel the same way too.12. How did the author feel the night before her new school?A. Tired.B. ConfidentC. Worried.D. homesick13.

Also, children who slept for shorter periods at night were more likely to be associated with borderline personality disorder at ages 11 and 12.The research, published in the journalJAMA Psychiatry, was the first time possible links between early childhood sleep problems and adolescent psychotic experiences and borderline personality disorder (BPD) symptoms have been examined.“We know from previous research that persistent nightmares in children have been associated with both psychosis and borderline personality disorder,” said lead author Isabel at theInstituteofMental Healthat theUniversityofBirmingham.“But nightmares don’t tell the whole story. We’ve found that, in fact, a number of behavioral sleep problems in childhood can point towards these problems in adolescence,” she said.Adolescence, typically defined as the ages between 10 and 19, is a key period in human developmentbecause of brain and hormonal changes, anditis now thought to be when many mental health problems start.Prior research inAustraliafound that babies with persistent severe sleep problems in their first year were at greater risk for anxiety and emotional issues in later childhood. Sleep problems in children and adolescents have been shown to predict the development of various emotional and behavioral problems, including depression, anxiety, attention-deficit hyperactivity disorder, risk-taking and aggression. However, findings have been inconsistent, especially when based on objective measurements of sleep, rather than parental reports.Sleep and mental health are closely connected in adults, with sleep problems increasing the risk for developing particular mental illnesses as well as resulting in mental health issues.4. What can we know from paragraph 3?A. Childhood sleep problems probably cause youth mental health problems.B. Severe sleep problems in childhood lead to emotional issues.C. Persistent nightmares in children are closely related to psychosis.D. The research has not been known to the public.5. What does “it” refer to in paragraph 6?A. Adolescence.B. Key period.C. Human developmentD. Hormonal change.6. According to the Australian research, older children who had long-term serious sleep issues at one year old are more likely to ________.A. grow slowlyB. develop attention-deficit hyperactivity disorderC. do badly in lessonsD. suffer from anxiety7. Which of the following can be the best title for the text?A. A Study About Childhood Sleep Problems Is Under ProgressB. Pay Attention to Children Who Lack SleepC. Childhood Sleep Issues Linked to Adolescent Mental Health ProblemsD. How to Help Children Develop a Good Sleep HabitCSport is not only physically challenging, but can also be mentally challenging. Criticism from coaches, parents and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress canbe physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents and coaches’ criticisms to heart and find faults in themselves.Coaches and parents should also pay attention that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find faults with youngsters’ performances. Positive support should be provided regardless of the outcome. Research indicates that positive support motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.8. An effective way to prevent the burnout of young athletes is_____________.A. to make sport less competitiveB. to increase their sense of successC. to reduce their mental stressD. to make sport more challenging9. According to the passage, sport is positive for young people in that_____________.A. it can help them learn more about societyB. it enables them to find faults in themselvesC. it can provide them with valuable experiencesD. it teaches them how to set realistic goals for themselves10. Many coaches and parents are in the habit of criticizing young athletes_____________.A. believing that criticism does good to their early developmentB. without realizing criticism may destroy their self­confidenceC. in order to make them remember life’s lessonsD. so as to put more pressure on them11. According to the passage parents and coaches should_____________.A. pay more attention to letting children enjoy sportB. help children to win every gameC. train children to cope with stressD. enable children to understand the positive aspect of sportDA world in which extinct creatures could be brought back to life came a step closer yesterday. Australian scientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active. Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活) creatures that have been extinct for far longer.“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very important step in bringing back those animals that are extinct. And while I think that technically it is still pretty difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will be brought back to life in my lifetime.”The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed the equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally, suggesting the tiger gene had been activated.Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce (引起) a functional response in another living organism”.However, the animal’s entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments could encourage people’s indifference to the protection of endangered species.“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is nothing to worry about because we can fix it up later.”12. What does the underlined word “breakthrough” in the l paragraph refer to?A. Scientists have recreated new animals.B. Scientists have resurrected endangered animal.C. It has turned out that some creatures would not go extinct.D. A tiger gene has been extracted successfully and activated.13. Scientists are carrying out the experiments in order to ________.A. bring extinct animals back to lifeB. transplant the genes of tigers into other animalsC. find out what factors lead to the animals’ extinctionD. find a new way to extract animals’ DNA14. Mike Archer thinks that ________.A. scientists now have no technological difficulty reconnecting extinct animalsB. it’ll be a century or so before a Tasmanian tiger walks on the earth againC. humans have come closer in reconnecting extinct animalsD. reconnecting extinct animals is impossible15. We can learn from Mick Mooncy’s words that_________.A. he thought it unnecessary to worry about endangered animalsB. his opinion is in contrast with that of the Tasmanian GovernmentC. he thought people should be encouraged to protect endangered animalsD. he is concerned that bringing extinct animals back to life may have a negative effect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。
