广东省高一下学期期末英语试卷(附答案)
广东省高一下学期期末英语试卷(附答案)学校:___________姓名:___________班级:___________一、阅读理解There’s a day for just about everything, and the United Nations has designated May 20 as World Bee Day to celebrate the pollinators (传粉昆虫) dwelling in hives, fields and gardens around the globe since 2015. It draws much concern on bees and there’s a good reason to pay attention to them.“There are 20,000 species of bees around the world and a lot of these bees are in decline,” says Hien Ngo, a pollinator expert from the UN’s Food and Agriculture Organization. That includes honeybees, of course, but Ngo says they only make up a minority of all the kinds of bees in the world. Climate change, pesticides and habitat loss are putting many of those species a risk.“Bees really provide for us in many ways, like food and human well-being. They’re also important to our culture, dating back thousands of years in terms of heritage, inspiration of art,” Ngo says. They even provide inspiration for TikTok, where Erika Thompson,a professional beekeeper in Austin,Texas, shares her work.“The landlord wanted to call an exterminator (根除者), but the family who lived here wanted to save the bees, so they called me,” she says in her video.Her fans watch with happiness — and sometimes a little horror-as she picks up mounds (成堆) of bees with her bare hands and then moves them somewhere safer.“I’ve removed bees from a lot of crazy places,” Thompson says. “You know, I’ve removed bees from homes, RVs, tires, speakers and even a toilet.”Thompson’s work is about more than getting millions of views per video. “Bees are just a key factor in creating diverse and healthy ecosystems,” she notes. 1.What can we know about World Bee Day?A.It has a long history of hundreds of years.B.It is celebrated on May 22 every year.C.It is designated by the United Kingdom.D.People pay more attention to bees because of it.2.Which factor that makes many bees in danger is NOT mentioned?A.The change of climate. B.The shortage of food.C.The damage to their habitat. D.The application of pesticides. 3.What’s Ngo’s attitude towards celebrating World Bee Day? A.Unconcerned. B.Neutral (中立的).C.Negative. D.Supportive.4.What’s the best title for the text?A.A Video-on BeesB.How to Celebrate World Bee Day?C.Why Should We Celebrate World Bee Day?D.How Can We Human Beings Protect Bees?I live in central London. It’s crowded. I see tons of people every day. The Uber driver. The office workers at rush hour. The cashiers at Sainsbury’s ... Deep in my thoughts, I encounter and interact with people mindlessly like a robot sometimes, without giving it much thought. It’s becoming rare for me to make spontaneous (自发的) friendships.My mom was and still is the queen of spontaneous friendships. She is the kind of person who will talk to a cashier and know her life story, talk to a sales assistant and become her friend, and talk to a man sitting nearby, get his number and have me visiting his workplace to get advice on job hunting. These mindless chats have brought her many friends, and they have also solved many problems. I can’t remember how many times she did her magic and pulled herself out of a bad situation. Sometimes I wish I could be more like her. But on reflection, it’s something I can practice and you can too.For me to change, I had to make a habit of some sort. Here are the three affirmations (肯定) I tell myself every day to be more open to people.We are all fellow humans. We are all in this world together so we might as well be friendly and make a connection with a fellow human.Today is going to be a great day. Maybe I’ll meet someone who will make my day.I might be saved by a stranger. I might even meet my future employer before evenapplying.Opportunities are created by people. Whether it is a job or anything else, opportunities come from people talking to each other.So next time you get your coffee, ride with a driver, wait in line or even sit in the underground, don’t be afraid to interact with a stranger. It will affect their day; it will affect yours and you might get to that opportunity or solution that was lying in them, waiting to be found.5.Why does the author say that he is like a robot?A.He has to work hard.B.He is as smart as a robot.C.He has little time to enjoy his life.D.He seldom makes a connection with strangers.6.What do we know about the author’s mother?A.She has good people skills. B.She is fond of giving advice. C.She has strong belief in magic. D.She is unaware of her privacy concerns. 7.What did the author think about what his mother did?A.It was helpful to her. B.It was none of her business.C.It should be more spontaneous. D.It failed to solve any problems. 8.What does the author suggest?A.Staying away from strangers.B.Keeping in touch with your old friends.C.Communicating with those you encounter.D.Avoiding sharing personal information with others.On James Owen’s 70th birthday, he saw a video of himself bending the top of his body forward and raising his shoulders and back and walking slowly up to the platform where he was giving a talk. “I looked like an old man,”says Owen,who builta successful career on Wall Street. Even worse, he felt like an old man. He was about25 pounds overweight and had trouble with his back, knees and shoulders.Later, instead of giving in to age, Owen decided to set an ambitious five-yeargoal.He wanted to be pain-free, and he decided the way to get there was through exercise-even though at the time he couldn’t do a single push-up. Owen began walking though he was out of breath after five minutes. But that didn’t discourage him. He kept at the walks every day, along with some stretching. Once he had those basics down,he started lifting weights and hired a personal trainer to teach him and design a routine he could follow on his own. The last piece was finding other activities he enjoyed,which turned out to be cycling and swimming.In less than five years, Owen was able to do three sets of 50 push-ups each and walk for miles each day. And yes,he was free of aches and pains“Aging is only about 25% genes, and the rest is lifestyle,“he says.“As long as you’re still mobile, it’s never too late to become more healthy.”Owen used his experience to write a book called Just Move! A New Approach to Fitness After 50,in which he details how older adults can safely get off the couch and add more movement to their lives. He says,“Think of it as movement not exercise.Get started even if you walk just three blocks, which was all I could manage at first.”He adds,“The key is slow and steady progress. Not every investment pays off,but it is the best investment I’ve ever made in my life.”9.What can we learn about Owen from the video?A.He was a tough guy.B.He was in bad physical condition.C.He was overweight but straight in shape.D.He was wealthy and enthusiastic about exercise.10.Why did Owen decide to set a five-year goal?A.To relieve pain.B.To lose weight.C.To write a book.D.To encourage investment.11.Which of the following does Owen agree with?A.It’s better to get started earlier.B.Genes play a key role in anti-aging.C.Healthy lifestyle is vital in delaying aging.D.Exercise quickly promotes physical recovery.12.What can be concluded from the text?A.Bad news has wings. B.A good medicine tastes bitter. C.Don’t judge a book by its cover. D.It is never too old to work out.It appears that language can have a fascinating effect on the way we think about time and space. A growing number of experts believe language can influence how we think just as our thoughts and culture can shape how language develops.Cognitive scientist Lera Boroditsky, one of the pioneers of research into how language manipulates our thoughts, has shown that English speakers typically view time as a horizontal (平的) line. They tend to view time as travelling from left to right, most likely in line with how you are reading the text on this page.Languages also encode (编码) time in their grammar. In English, the future is one of three simple tenses, along with the past and the present — we say “it rained”, “it rains” and “it will rain”. But in German, you can say Morgen regnet, which means “it rains tomorrow”— you don’t need to build the future into the grammar.But does this affect how we think? In 2013, Keith Chen, a behavioral economist at the University of California, set out to test whether people who speak languages that are “futureless” might feel closer to the future than those who speak other languages. For example, German, Chinese, and Japanese have no linguistic barrier between the present and the future, while “futured languages” , such as English, French, Italian and Spanish, encourage speakers to view the future as something separate from the present.He discovered that speakers of futureless languages were more likely to engage in future-focused activities. They were 31% more likely to have put money into savings in any given year and had gained 39% more wealth by retirement. They were also 24% less likely to smoke and 29% more likely to be physically active.It is becoming increasingly clear that language is influencing how we think about the world around us, which is not to say that any one language is “better” thananother. But being aware of how languages differ can help you think, navigate and communicate better. And while being multilingual (多语的) won’t necessarily make you a genius, we all can gain a more flexible understanding of the world by learning a new language.13.What does the underlined word “manipulates” in paragraph 2 probably mean? A.Weakens. B.Shapes. C.Impacts. D.Deepens. 14.How does the author organize paragraph 3?A.By listing figures. B.By giving examples.C.By giving definitions. D.By explaining the reasons.15.What were speakers of futureless languages likely to do?A.Smoke and drink.B.Be mentally active.C.Spend money without restriction.D.Take part in future-focused activities.16.What does the author intend to tell us in the last paragraph?A.One language is much better than another.B.Being multilingual can help you become a genius.C.Learning a new language can change your way of life.D.Language has an impact on how we think about the world.二、七选五Now I live in Paris. Actually, I don’t mind the food or the people, but I do care about the land that is extraordinarily lack of characteristics of hiking. I enjoy being outdoors and hiking, but Paris’s natural resources don’t hold much potential for my bent. So when my dad asked if I wanted to go hiking with him, I was overjoyed. 17 . It turned out that I was too optimistic.We started our main hike up Flattop Mountain. As we hiked it was much more challenging than I expected. 18 . The path is winding and we saw mountains towering over the green valleys and cliffs that seemed endless. What amazed me most was that thick clouds enveloped the mountainsides. 19 .I stared up at the top to see how much farther we had to go and I began to worrythat I wouldn’t finish it. 20 . It made me doubtful about my persistence (坚持). But when we looked back at the path that faded in the distance, I was filled with fulfillment with seeing how much we had done.As I was hiking, I started to reflect on how hiking was similar to other aspects of my life. 21 . It reminded me of my struggles in my classes and the difficulties I had to overcome. I spotted that the process of learning isn’t always the most fun, but the fulfillment after seeing how much I had finished just increases the thirst for knowledge, causing me to long for more learning. Looking down at the mountain I was content but never fully satisfied. Having considered a lot, I was determined to pursue the summit (山顶).A.Hiking could make me fly.B.Hiking gave time for my mind to wander.C.I thought I would finish the journey with ease.D.But I was shocked at the beauty surrounding me.E.I was satisfied with the landscape along the way.F.It was unlike anything I had ever witnessed before.G.A recent ankle injury had left me unsure of my physical capabilities.三、完形填空A seven-year-old boy has become one of the youngest people to cycle from Londonto him.Rupert’s life was 32 forever when his Dad passed away in 2019. As Rupert was only four at the time, it was 33 for him to understand what had happened. With the arrival of the coronavirus pandemic, it ended up being a really 34 time for Rupert and his Mum. That was when the Children’s Bereavement Centre cameto help. They taught Rupert to 35 some of the emotions he was feeling and also 36 him to other children so that he felt less 37 .With some help from his Mum, Rupert decided to 38 this challenge to raise lots of money for the Centre so they can support more families. “We are absolutely 39 that Rupert has decided to do so. It’s a great 40 for anyone to cycle 200 miles from London to Paris, let alone a seven-year-old boy.

Here are some ways to spot the false reviews.There are plenty of __5__ stores which pay people to write good reviews of their products. __6__, these people write very short reviews, with sentences often like “Of all the bags I have used, this one is the best ever.”Look out, if the same product has multiple reviews published within a short time frame.

Choose the one that fits best according to the information given in the passage.ATanzania Tarangire is a national Park which lies in Tanzania. The park itself covers an area of around 2,850 square kilometers, making it the sixth largest park of its kind in the country. I recently visited Tarangire to see what it was like….One of the first sightings upon entering the park which I found was a huge herd(群)of elephants. Our guide told us that Tagrangire was probably the best place in Tanzania to find large herds of elephants, and that their population in the park was around 2,500. We continued to watch the elephants as they stood under trees and scratched themselves against the trees to hit the spot of an itch(痒处).To the right of the elephant herd, we noticed a big tree! Our guide informed us that this was a Baobab tree and that they could live for hundreds of years. Compared with this tree, the elephant just looked like dwarfs(侏儒)! We were informed that Tarangire was one of the best National Parks in Africa to see so many Baobab trees.As we continued our drive through the park, we finally reached a watering hole. Our guide warned us that there were lions all around us. It took us all a while to find them, but there they were! Most of them are resting in the shade under brushes, but there was one that was drinking from the watering hole directly in front of us. We then noticed just to our right, therewere a couple of fresh zebra corpses(尸体)— it seemed as if the lions which were resting had killed them! We were unlucky not to have seen the actual kill, as our guide had mentioned that the zebra corpses were fresh and the kill had occurred within the last hour.Our final big sighting was one that none of us were expecting to see, even our guide! We pulled over to where there was a large gathering of cars, with a sleeping leopard(美洲豹)there! We took photos happily and excitedly and observed its surprising body before returning to our hotel as it was getting late.So, I hope you enjoyed my description of Tarangire, and that I have inspired you to add this amazing park to your very own Tanzania travel route.56. How did the writer travel in Tanzania Tarangire?A. By carB. On horsebackC. On footD. By bicycle57. Which statement is correct about the park?A. It covers an area of about 2,580 square kilometersB. There are a lot of Baobab trees in it.C. It is the largest park of its kind in the countryD. Their population in the park was around 2,00058. What does the writer think of his trip in Tanzania Tarangire?A. BoringB. ChallengingC. DangerousD. Enjoyable59. What did they see when they stopped with some other cars?A. A large herd of elephantsB. Some lionsC. Some zebrasD.A leopard60. What may this passage be probably taken from?A. A dairy entryB. A travel guideC. An advertisementD. A travel agencyBSome students get so nervous before an exam that they do poorly even if they know the material. Sian Beilock, a psychology professor at the University of Chicago, has studied these highly anxious exam-takers.“They start worrying about the results. They might even start worrying about whether this exam is going to prevent them from getting into the college they want. And when we worry, it actually uses up attention and memory resources that you could otherwise be using to focus on the exam,” says Sian Beilock.The researchers tested the idea on a group of 20 anxious college students. They gave them two short math exams. After the first one, they asked the students to either sit quietly or write about their feelings about the coming second exam.The researchers added to the pressure. They told the students that those who did well on the second exam would get money. They also told them that their performance would affect other students as part of a team effort.Professor Beilock says those who sat quietly scored an average of 20% worse on the second exam. But the students who had written about their fears improved their performance by an average of 5%.Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the exam.Professor Beilock says highly anxious students who wrote about their feelings got an average grade of B+, compared with a B-for those who did not.But what can they do if students do not have a chance to write about their fears immediately before an exam orpresentation? Professor Beilock says students can try it themselves at home or in the library and they can still improve their performance.61. In which paragraph does the author introduce the background(背景) of his study?A. In the first paragraph.B. In the second paragraph.C. In the third paragraphD. In the last paragraph.62. According to Sian Beilock, if you want to succeed in an exam you should ______.A. be as serious as you can about the exam.B. focus your attention on the exam.C. set clear study goals and keep themD. make a careful preparation for the exam63. We can infer from the study that students who sit quietly before the exam ______.A. are more likely to get better exam results.B. have a positive attitude towards exam results.C. worry more about the exam in their mind.D. have a strong will to be successful in the exam.64. The underlined word “it” in the last paragraph refers to “______”.A. looking for a chanceB. preparing for the examC. writing about the feelingsD. taking the exam65. If a student writes about his feelings before an exam, he ______.A. will improve his exam resultB. can keep a good memory of the examC. will get support from his teachersD. will forget what he has prepared for the examC66. Why does the author mention Bell and Edison at the beginning of the text?A. To remember both of them.B. To prove their wisdom.C. To introduce the topic of the text.D. To explain their relationships.67. Philo Farnsworth got the idea for TV from ______.A. the radioB. science booksC. potato fieldsD. a machine68. According to the text, how old was Philo when he finished his invention of TV?A. 27 years old.B. 21 years old.C. 33 years oldD. 39 years old69. The underlined part “building up” in the last paragra ph probably means “______”.A. startingB. sellingC. making biggerD. putting up70. Which is the correct order of the following events?a. Two rich men gave Philo money to do experiments.b. Philo sold his own company.c. Philo beat RCA in law.d. Philo fixed broken radios.e. Philo showed his invention to others.A. e, d, c, b, aB. d, a, e, c, bC. d, c, e, b, aD. a, c, b, d, ePart IV Writing (35 marks)Section A (10 marks)Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage. Write NO MORE THAN THREE WORDS for each answer.CPR is cardiopulmonary resuscitation (心肺复苏). It forces air into the lungs and pumps(用泵抽) blood and oxygen to the brain in order to increase the chances that a person whose heart stopswill survive. It increases the chances that he or she will suffer little or no brain damage.The American Heart Association suggests two ways to perform CPR. One combines the use of hands to pump the victim’s chest(胸腔)with rescue breathing. The other method is called “Hands-Only CPR”, which is for people who are unwilling or unable to perform rescue breathing. Some people fear infection(感染). Others say they are afraid of making the patient worse.But the American Heart Association strongly asks people in contact with a victim(受害者) to take action and tells how to take it. It says you can recognize a person needing CPR. He or she is unconscious(无意识) -- unable to communicate or react to surroundings or speech. His or her skin has lost color. The person is not breathing. If such conditions describe the situation, chances are the heart has stopped beating.You should act by calling for help, or sending someone else. Even if you cannot do mouth-to-mouth rescue breathing, you can perform Hands-Only CPR. You can do chest compressions(压迫) that help to keep blood flowing to the brain and the heart. To perform the compressions, place one hand over the other and press firmly on the center of the victim’s chest. Push down about five centimeters. Aim for one hundred compressions each minute.Doctor Sayre suggests that medical workers do both the breathing method and chest compressions as usual. He says some victims, including babies, need the mouth-to-mouth breathing with the compressions. Still, the doctor says it is better to do just chest compressions than to do nothing.Title: CPR71____________To increase the chances of survivalTypes of CPR•The use of hands to pump the victim’s chest with 72. ____________.•73. ________________.Who to perform “Hands-Only C PR”People ---• unwilling or unable to perform CPR•74. ____________• afraid of making the patient worseWho to receive CPRPeople ---• 75. ____________• 76._____________ or react to surroundings or speech• pale in pale• unable to breathe77. _________ CPR• Place one hand on the other• Press firmly on the center of 78. _________•79. ____________ about 5 centimeters• Perform 100 compressions each minuteDr. Sayre’s suggestions•In usual cases:the breathing method and chest compressions.•In some cases (babies related):80. ____________.Section B(10 marks)Directions: Read the following passage. Answer the questions according to the information given in the passage and required words limit.March 22nd every year has been the World Water Day since 1993. Everyone knows that over 70% of our planet is covered with water, but do you know that only 3% of the water is fresh and less than 1% of this fresh water is available for human use?Water shortageThe World Bank reports that 80 countries now have water shortages, while 40% of the more than 2 billion people, have no access to clean water. Fresh water is such a life-or-death issue(问题) in many parts of the world that every eight seconds a child dies from drinking dirty water.How to save waterTurn off the tap while you brush you teeth in the morning and before bedtime, and you can save up to 8 gallons of water! That adds up to more than 200 gallons a month, enough to fill a huge fish tank that holds 6 small sharks!Keep your shower under 5 minutes long. In fact, a 5-minute shower uses more water than a person living in poverty in a developing country uses in an entire day.Fix the leak. If your toilet has a leak, you could be wasting about 200 gallons of water every day. That would be like flushing your toilet more than 50 times for no reason!We each share responsibility for the sustainable management(可持续管理) of our water resources, which means using less water at home, in the workplace, at school, on holidays, on the farm,… everyone, everywhere, ev ery time.81.

It‟s time foryou to come out and 24 the world your beautiful colors. You can‟t do that if you stay in your cocoon.” The caterpillar 25 followed their advice. As soon as he came out, he found he had become a 26 butterfly and could have such great fun flying around.We all have a choice to make in life.

AWhen it comes to President Obama, most of his personal business is already known by the public. Personal information about his children, Malia and Sasha, however, has been kept a little more under wraps.The New York Times recently released a list of rules that Michelle Obama has mentioned over the years that Malia and Sasha must follow during their time in the White House, as well as in general. See how the first family educates their children.The girls must write reports about what they‟ve seen on their trips, even if it‟s not required by their school.Malia may use her cell phone only on the weekends, and she and her sister cannot watch television or use a computer for anything but homework during the week.Malia and Sasha have to play two sports one they choose and one selected by their mother.Malia must learn to do laundry before she leaves for college.The girls have to eat their vegetables, and if they say they are not hungry, they cannot ask for cookies or chips later.While these might be shocking to some, Michelle said, “They‟re not little princess. It‟s just basic rules, boundaries, and expectations that we would have normally.”Michelle also mentions another set of rules.The girls must do their chores, though the White House has a large staff. Malia and Sasha have chores of their own.They must play a team sport, because it‟s about learning how to play on a team, how to lose and how to win gracefully.It sounds like Michelle and Barack want the best for their kids and to make them as well-rounded as possible.

I was so seriously injured that I was in a coma for more than two months at Prince Georges Hospital.I suffered a lot from the experience of dying eight times during my coma and I coul dn‟t open my mouth to talk or to communicate when I eventually came around. At that time, it seemed that walking was never going to happen again due to all the extreme injuries. Just like my body, my dreams were completely destroyed. But I was not going to let my injuries stop me from realizing my dreams.After receiving a total of 15 operations and 36 blood transfusions, I had to make every great effort to learn to talk, eat, walk, shower, and live on my own again. When I was out of hospital, I still had to go to outpatient therapy (治疗,理疗)in Waldorf, Maryland. After I spent a few monthsin a wheelchair, I took baby steps to walk on my own. It was a miracle that I was able to walk again, but I still wanted to prove that I could not only walk, but also run. When it came true, I wanted to get back into the pool again. After having a few lung tests, I was able to go in the pool a little bit each week. After a few months of swim training, I began my freshman year at St. Mary‟s College of Maryland and then became a proud member of the swim team.By telling my story, I want to make a positive influence on the world. I am just trying to live each day to the fullest and inspire other people never to give up their dreams no matter how bad a situation is to them. I remember when I was still in my hospital bed, I would have my mom and dad push me round in my wheelchair to the other rooms to see the other patients and chat with them and their family members. I wanted to let them know that everything was going to be okay. Somehow, things would work out for the best.46. The underlined word “coma” in Paragraph 2 probably has the meaning of “_______”.A. operationB. unconsciousnessC. treatmentD. emergency47.

What is the correct order of the following events?a. went to outpatient therapyb. received membership of the swim teamc. was pushed around to visit other patientsd. walked like a babye. learnt to live all by himselfA. d、a、c、b、eB. e、c、d、a、bC. d、c、a、b、eD. e、c、a、d、b49. In the last paragraph, the author mainly wants to show _______.A. his positive influence on other patientsB. his meaningful lifeC. his purpose of sharing his storyD. his great achievements50. The best title for the passage would be “_______”.A. Attitude is everythingB. Actions speak louder than wordsC. Everything happens for a reasonD. A good beginning is half doneCMost young people enjoy some form of physical activity. It may be walking, cycling or swimming, or in winter, skating or skiing. It may be a game of some kind of football, hockey, golf, or tennis. It may be mountaineering.Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risk on high mountains? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their leisure.Mountaineering is a sport and not a game. There are no man-made rules, as there are for such games as golf and football. There are, of course, rules of a different thing that it would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.If we compare mountaineering and other more familiar sports, we might think that one big difference is that mountaineering is not a "team game". We should be mistaken in this. There are, it is true, no "matches" between "teams" of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.The mountain climber knows that he may have to fight forces that are stronger and more powerful than men. He has to fight the forces of nature. His sport requires high mental and physical qualities.A mountain climber continues to improve in skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions are in their early twenties. But it is not unusual for a man of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they probably climb with more skill and less waste of efforts, and they certainly experience equal enjoyment.51. What's the meaning of “leisure” in Paragraph 2?A. spare timeB. restC. entertainmentD. enjoyment52. Mountaineering can be called a team sport because _________.A. it is an Olympic eventB. mountaineers depend on each other while climbingC. teams compete against each otherD. there are five climbers on each team53. Why are many people attracted by mountaineering?A. Because they do esn‟t have to be restricted by rules while climbing.B. Because they can improve their skill when they are on a rock face.C. Because they can learn to fight the forces of nature while climbing.D. Because they can enjoy a lot of fun while climbing.54. It can be inferred from the passage that ______.A. people show interest in mountaineering because it is a team gameB. physical quality is more important than mental one for climbersC. a mountain climber would pass his best by the age of thirtyD. it is possible for an old man of sixty to climb the Alps55. What is the passage mainly about?A. Mountaineering Is Different from Golf and Football.B. Mountaineering Is More Attractive than Other SportsC. MountaineeringD. Mountain ClimberD“A good book for children should simply be a good book in its own right,” says Mollie Hunter. Born and brought up near Edinburgh, Mollie has devoted her talents to writing primarily for young people. She firmly believes that there is always and should always be a wider audience for any good book whatever its main market is. In Mollie's opinion it is necessary to make full use of language and she enjoys telling a story, which is what every writer should be doing. “If you aren't telling a story, you're a very dead writer inde ed,” she says. With the chief function of a writer being to entertain, Mollie is indeed an entertainer. “I have this great love of not only the meaning of language but of the music of language,” she says. “This love goes back to early childhood. I've told stories all my life. I had a school teacher who used to ask us what we would like to be when we grew up and, because my family always had dogs, and I was very good at handling them, I said I wanted to work with dogs, and the teacher always said …Nonsense, Mollie, dear, you‟ll be a writer.‟ So finally I thought that this woman must have something, since she was a good teacher and I decided when I was nine that I would be a writer.”This childhood intention is described in her novel, A Sound of Chariots, which althoughwritten in the third person is clearly autobiographical and gives a picture both of Mollie's ambition and her struggle towards its achievement. Thoughts of her childhood inevitably(不可避免地)brought thoughts of the time when her home was still a village with buttercup meadows and strawberry fields—sadly now covered with modern houses.“I was once taken back to see it and I felt that somebody had lain dirty hands all over my childhood. I'll never go back,”she said. “Never.”“When I set one of my books in Scotland,”she said,“I can recall my romantic feelings as a child playing in those fields, or watching the village blacksmith at work. And that's important, because children now know so much so early that romance can't exist for them, as it did for us.”56. What does Mollie Hunter feel about the nature of a good book?A. It should not aim at a narrow audience.B. It should be attractive to young readers.C. It should be based on original ideas.D. It should not include too much conversation.57. In Mollie Hunter's opinion, which of the following is one sign of a poor writer?A. Being poor in life experience.B. Being short of writing skills.C. The weakness of description.D. The absence of a story.58. What do we learn about Mollie Hunter as a young child?A. She didn't expect to become a writer.B. She didn't enjoy writing stories.C. She didn't have any particular ambitions.D. She didn't respect her teacher's views.59. In comparison with children of earlier years, Mollie feels that modern children are .A. more intelligentB. better informedC. less eager to learnD. less interested in reality60. What's the writer's purpose in this text?A. To describe Mollie Hunter's most successful books.B. To share her enjoyment of Mollie Hunter's books.C. To introduce Mollie Hunter's work to a wider audience.D. To provide information for Mollie Hunter's existing readers.第二节:信息匹配(共5 小题;每小题2分,满分10分)/下面是一篇应用文及其应用场合的信息,请阅读下列应用文和相关信息,并按照要求匹配信息。
