However, no city will ever quite match Cádiz, where I spent six months studying as a student.Before that, I knew very little about Cádiz but I decided to take a risk and explore it. Well, the risk certainly paid off.Cádiz, Europe’s oldest city, hangs off Spain’s southern coast on a peninsula(半岛), surrounded almost entirely by water. As you leave the shady streets of the historical old city and explore more of it, you are met with vast areas of the blue Atlantic Ocean and white sandy beaches, which in my opinion are some of the best in Spain!One of the great things about Cádiz is the wonderful, rich culture of food and drink. There are little tapas(小吃)bars lining every street and most will serve tapas for around 1. 50~2 euros, meaning you can try a whole variety of Andalusian dishes.Cádiz has also come to be known as “The Singing City”. It comes from the annual carnival(狂欢节), one of the biggest in Europe. A very large number of people go to Cádiz to see it. During those ten days, Cádiz’s narrow streets are filled with the sound of singing as musical groups fight for a place in the contest, which takes place on the last Saturday of carnival. The songs perfectly show the sense of humor of the Gaditanos, who, besides being so warm and welcoming, are said to have the best sense of humor in Spain!That is my experience of Cádiz. a wonderful, typically Andalusian city which is often overlooked but well worth a visit. I am currently living in Huelva, just a short drive from Cádiz, so please pay attention to my next sharing!24. What does the word “that” underlined in paragraph 2 refer to?A. Studying in Cádiz.B. Competing in a match.C. Teaching a student.D. Becoming an explorer.25. What does the third paragraph mainly talk about?A. The unknown origin and long history of Cádiz.B. The beautiful life of people living in Cádiz.C. The geographic position and scenery of Cádiz.D. The author’s complex attitude towards Cádiz.26. Why is Cádiz called “The Singing City”?A. A number of local people enjoy humorous songs.B. Singing is everywhere during a big annual carnival.C. Many grand carnivals attract well-known singers.D. A lot of singing competitions take place each year.27. From which is the text most probably taken?A. A post on the Internet.B. A geography textbook.C. A travel brochure.D. A biography.CAre you a talkative person? Do you like chatting with your colleagues? Every day around the world, most people who go to work avoid making small talk with their colleagues once they get there.Some put on their headphones and keep their eyes low. Others will pretend to receive an urgent message that requires an immediate, life-or-death rapid response, which prevents them from doing pretty much anything else, including the conversation made while people are heating up lunch in the office microwave or while walking from the entrance of their office building to the nearest bus stop.If those sound familiar or if you’ve convinced yourself that avoiding small talk with colleagues is smart self-preservation and that the risk of saying something offensive or coming across as socially unskillful is not worth the reward of connecting with somebody, then there is a bad piece of news—your false logic could be costing you a higher position at work.Jamie Terran, a licensed career coach in New York City, said that small talk between colleagues builds rapport, which builds trust. “Rapport is the feeling that allows you to extend the deadline, or overlook smaller mistakes because it makes your colleagues to remember that we’re only human,” she added.However, many people underestimate how much their conversation partners like them. But it’s not necessary. Imagine that after you have an awkward small talk with your colleague, do you think that the colleague you just talked with is a terrible conversationalist? No. You just feel bad about yourself. And your colleague feels the same about himself or herself.If you’re generally anxious in social situations, Terran suggested coming up with questions or stories from which you can pull. “Whether or not you share personal information about yourself is up to you, but discussing things you truly care about always works,” she said. “Topics related to your professional field, for example, thesports you do well, is a great place to start.”28. How do most people avoid chatting with their colleagues?A. By asking their colleagues to stay far away.B. By getting themselves occupied on purpose.C. By reading something unrelated to their work.D. By devoting themselves fully to the deadlines.29. What may people lose if they avoid small talk with colleagues?A. Smart self-preservation.B. Trust in their colleagues.C. Professional and social skills.D. A chance for job promotion.30. What do people worry about after an awkward chat with their colleagues?A. Their colleagues will overlook their efforts.B. They are likely to make more big mistakes.C. Their colleagues may think poorly of them.D. They will lose heart during the coming days.31. What does Jamie Terran strongly suggest about making small talk?A. Making up funny stories about others.B. Talking about something you are good at.C. Choosing serious topics for discussion.D. Sharing private information about yourself.DCorn is among the most commonly consumed grains on the planet. Globally, the average human will consume 70 pounds of corn each year! That’s a whole lot of corn that needs to be grown each year, and that’s not even accounting for corn being grown for animal consumption and biofuel. Just like many other popular foods, farmers are finding it difficult to get enough corn produced.Of course, complicating matters is the fact that corn is a tropical(热带的)plant, meaning farmers can’t produce it during the colder months of the year. Now, researchers from Cornell University’s Boyce Thompson Institute have developed their own solution: a new variation of corn that recovers much more quickly after being exposed to cold temperatures.Lead researcher David Stern, president of the Boyce Thompson Institute, and his team made this incredible breakthrough by building on research originally published two years ago. That study had discovered that increasing the levels of an enzyme(酶)called Rubisco in plants caused them to grow more rapidly and reach larger sizes. Rubisco helps plants turn atmospheric carbon dioxide (CO2) into sugar. Regarding corn specifically, Rubisco levels in corn drop considerably in cold weather.This time, the research team planted a large group of corn plants, and provided a portion of the group with more Rubisco. Then, they allowed all the plants to grow for three weeks at 77 degrees Fahrenheit (normal growing temperature for corn)before dropping the temperature to 57 degrees Fahrenheit for two more weeks. Finally, theyheated things up back again to 77 degrees.“The corn with more Rubisco performed better than regular corn before, during and after chilling(冷却),” explains first author Coralie Salesse-Smith. “In fact, we were able to reduce the severity of chilling stress and allow for a more rapid recovery.”All in all, the corn with more Rubisco was able to recover from the colder temperatures more quickly and with less damage done. The Rubisco corn plants grew to be taller. These results are very promising. However, Stern and his team say they’re still working on improving their approach.32. What makes the research particularly necessary according to the text?A. The great climate change.B. Lack of heat-tolerant corn.C. The large demand for corn.D. Corn’s insensitivity to climate.33. What did the researchers do during the study?A. They made those corn plants resist Rubisco.B. They assessed corn plants’ ability to absorb CO2.C. They removed all the chilling stress on corn plants.D. They exposed corn plants to different temperatures.34. What should the researchers think of the corn plant they developed?A. It has functioned well in solving global starvation.B. It is qualified enough to be grown around the world.C. It recovers from the colder temperatures more slowly.D. It isn’t yet completely perfect for chilling tolerance.35. Which of the following can be the best title for the text?A. Much More Corn Plants Are Badly NeededB. Corn Plants Aren’t Sensitive to Cold WeatherC. Scientists Have Developed Cold-resistant CornD. Tropical Corn Is Going to Become History Soon第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

B When Rachel Ratelle saw a news video of a burned koala trying to climb a tree to safety in fire-stricken Australia, she decided to do something about it. She looked up wildlife rescue and relief agencies in Australia to find out what they needed most. Besides donations, many organizations asked for hand-sewn and knitted pouches(袋子) and wraps for koalas and other animals that were burned or had lost their homes and parents in the fires. This idea attracted Ratelle, but there was just one problem. "I'd never sewn in my life," said Ratelle, 17, a senior at Rancho Buena Vista High School in Vista, US. "Giving money seemed like something too simple. But I wanted to directly help these animals by doing something myself so I decided to learn how to sew." Over the next few months, Ratelle bought her own sewing machine and taught herself how to sew via videos online. Then she purchased 18 yards of fabric and sewed 25 pouches of different sizes and shipped them off to FAWNA, one of several relief organizations that have rushed to rescue koalas, kangaroos and other species suffering from burns. A week later, she received a photo from FAWNA with a young koala in one of her larger pouches. "It made me feel like I contributed to the world and it showed how a simple act ofkindness can go a long way," said Ratelle, who hopes to study biology for a future career as a nurse practitioner.Several craft(手工) websites around the world have appealed to people to make the animal pouches. Karen Newberry and her two daughters Madison, 12, and Rochelle, 8, from San Diego also offered their help in such a way. For Newberry, “It was a big push that made us crafters, sewers realize there's something more we can do than just make things for ourselves,” she said.4. What does the first paragraph mainly talk about?A. What inspired Ratelle to learn to sew.B. The poor living conditions of Australian animals.C. What is needed to save koalas and other species.D. Different ways to help koalas and other animals.5. How did Ratelle feel when she received a photo from FAWNA?A. Calm.B. Surprised.C. Proud.D. Disappointed.6. What can we learn from the last paragraph?A. It is challenging for crafters and sewers to do relief work.B. Life is not easy for crafters and sewers in Australia.C. People should stay united through difficult times.D. Many people are involved in helping injured animals.7. What's the best title for the text?A. Helping Injured WildlifeB. A Big Bushfire in AustraliaC. Making Animal PouchesD. Relief Agencies in AustraliaCThe snow in Antarctica is turning green and scientists say climate change may be to blame. According to a study at the Cambridge University, microscopic algae blooms (藻类爆发) across the surface of the snow is slowly turning Antarctica’s winter white landscape green. Although micr oscopic, scientists say they’re able to see the “green snow” from space when the algae blooms all together.Researchers created a large-scale map of green snow algae along the Antarctic coast using a combination of satellite data and on-the-ground observations over the course of two summers. The study found that the green snow algae bloomed in warmer areas where the average temperatures are just above 0℃ during the southern hemisphere’s (半球的) summer months from November to February.“As Antarctica warms, we predict the overall mass of snow algae will increase,” said Dr. Andrew Gray, lead author of the paper, and a researcher. Researchers say larger blooms of algae can be found north of the Antarctic and South Shetland Islands, where it can spread to higher ground as the snow melts.The team also discovered some sea birds and mammals influenced the distribution of algae. Over 60% of algae blooms were found within three miles of a penguin settlement. Scientists hypothesize this may be due to their droppings, wh ich act as a “highly nutritious fertilizer.”“This is a significant advance in our understanding of land-based life on Antarctica, and how it might change in the coming years as the climate warms,” said Dr. Matt Davey in the University of Cambridge’s Depar tment of Plant Sciences, who led the study.8. What is turning the Antarctic snow green?A. The melting of snow.B. The blooming algae.C. The beautiful landscape.D. The balanced temperature.9. Where is microscopic algae most likely to bloom in Antarctica?A. North of the Antarctic.B. West of the South Pole.C. South of the Antarctic.D. Around the southern hemisphere.10. What does the underlined word “hypothesize” in Paragraph 4 probably mean?A. confirm.B. support.C. assume.D. warn.11. What can we learn from the text?A. Penguins feed on microscopic algae.B. Antarctic algae grow under the snow.C. Ground observation lasted for four months.D. Animal droppings contribute to the algae blooms.DCall it a mobility system or a wheelchair—it can be seen at the Tokyo airport moving on its own. It is helping with social distancing while fighting the spread of the coronavirus. It also helps older passengers and those who otherwise need assistance walking the last few steps to the boarding gate.The mobility system seats one person and runs on its own without hitting anything. It has a pre-programmed path of about 600 meters at Tokyo's Haneda International Airport. It was shown on Monday by WHILL, the company behind the technology.WHILL Chief Executive Satoshi Sugie said robotics and self-driving technology reduce the need for a human at the wheel. They are good for these times of "living with" coronavirus. The ride lasts several minutes. It travels from the security area to the boarding gate at a speed of 3.5 kilometers per hour. But many people hope the technology can help in other places, such as hospitals or parks. The technology uses sensors and cameras to see a clear path and avoid hitting those walking toward it. It could also help Japan free up laborers. Japan, like many other nations, suffers from a labor shortage. The technology could free a worker to do another job.Tests have been carried out at several airports since last year, including John F. Kennedy International Airport in New York. The company hopes to put it in airports around the world.The person on the machine can start or stop it through a simple controller.It runs on batteries and is programmed to return to where it started when its passenger gets off. Anyone needing help walking long distances can use it at Terminal One at Haneda airport. It is called the “last-mile mobility”, says WHILL.12. What do we know about the mobility system?A. It can seat more than one person.B. It runs with the assistance of a controller.C. It helps older passengers to the boarding gate.D. It has a flexible path of about 600 meters.13. What does “T hey” in Paragraph 3 refer to?A. Humans at the wheel.B. The needs for human beings.C. These times of "living with" coronavirus.D. Robotics and self-driving technology.14. What plays an essential part in the technology?A. Sensors and cameras.B. The speed of the machine.C. The path of the ride.D. The distance of the ride.15. What can we infer from the last two paragraphs?A. The system runs completely on its own.B. The system has been put into use in the US.C. WHILL will continue to test the system in airports worldwide.D. The system is controlled by a passenger to return to the start.第二节(共5 小题;每小题2 分,满分10 分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

Forstudentsinvolved in an innovative classroom project, they ______.A. may study a new modelB. are on the quickest way to be expertsC. will get more freedom during research projectD. have advantages of studying outside the classroom3. The article is probably taken from ______.A. a travel magazineB. a science reportC. a college websiteD. an academic journalBVijay Gupta is known to classical music lovers across the United States. He serves as first violinist for the Los Angeles Philharmonic. In that job, he often plays to large crowds, including many very rich people. When he is not performing, he organizes concerts for homeless people. “They have reminded me why I became a musician”,he said.Last week, Gupta was recognized for being a founder and the artistic director of Street Symphony. The group has performed at homeless shelters, jails and halfway houses for about eight years. Gupta is among the 25 winners of the 2018 MacArthur Fellowship, commonly known as the “genius grant”. Each winner will receive $625,000 over five years to use as they wish. The money is coming from a private group, the John D. and Katherine T. MacArthur Foundation. It awards grants(补助金) to people whose work it considers exceptional and that “inspires hope in us all.” Gupta said he got the idea for Street Symphony while teaching Nathaniel Ayers, a trained musician whose mental illness led to homelessness.The 31-year-old grant winner said he does not know yet how he will spend the money. He has been a performer since age seven and the award will give him “space t o breathe, plan and look ahead.”Another winner is Rebecca Sandefur, an associate professor of sociology and law in the University of Illinois. The Associated Press says her research actively supports new ways to involve poor communities in the U.S. justice system.47-year-old Sandefur created the first national mapping of civil legal aid providers. It shows which states had the financial resources to provide such aid and which did not. She also found that the cost of legal services is only one of the things preventing poor people from getting lawyers. Among the others are fears about unfairness in the legal system. Sandefur noted that a lot of attention has been paid to problems with the criminal justice system, but more attention must be paid to the civil side of the law, which also affects millions of people.4. Why did Gupta win the award?A. For his achievements in classical music.B. For performing for large crowds.C. For organizing a group playing for the homeless.D. For the friendship with Nathaniel Ayers.5. What do we know about Mac Arthur Fellowship?A. It is founded by the government.B. It offers $625,000 to 25 winners in 2018.C. It allows the winners to use the money freely.D. It awards people who make great contributions to society.6. What was the extraordinary thing that Sandefur did?A. She offered legal aids to the poor freely.B. She made the legal system fairer.C. She paid more attention to the criminal justice system.D. She made it easier to get legal help for the poor.7. Which can be the best title for the passage?A. Grant Winners, Inspiring the PoorB. The City Homeless, in Need of HelpC. Vijay Gupta, an Extraordinary ViolinistD. MacArthur Foundation, Awarding Exceptional workCTheir cheery song brightens many a winter’s day.But robins are in danger of wearing themselves out by singing too much.Robins are singing all night―as well as during the day,British-based researchers say.David Dominoni,of Glasgow University,said that light from street lamps,takeaway signs and homes is affecting the birds’ biological clocks,leading to them being wide awake when they should be asleep.Dr Dominoni,who is putting cameras inside nesting boxes to track sleeping patterns,said lack of sleep could put the birds’ health at risk.His study shows th at when robins are exposed to light at night in the lab,it leads to some genes being active at the wrong time of day.And the more birds are exposed to light,the more active they are at night.He told people at a conference,“There have been a couple of stud ies suggesting they are increasing their song output at night and during the day they are still singing.Singing is a costly behaviour and it takes energy.So by increasing their song output,there might be some costs of energy.”And it is not just robins that are being kept awake by artificial light.Blackbirds and seagulls are also being more nocturnal.Dr Dominoni said,“In Glasgow where I live,gulls are a serious problem.I have people coming to me saying‘You are the bird expert.Can you help us kill these gull s?’.During the breeding(繁殖)season,between April and June,they are very active at night and very noisy and people can’t sleep.”Although Dr Dominoni has only studied light pollution,other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise.However,some birds thrive(兴旺)in noisy environments.A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery.It is thought that they are taking advantage of their predators(天敌) escaping to quieter areas.8.According to Dr Dominoni’s study,what causes robins to sing so much?A. The breeding season.B. The light in modern life.C. The dangerous environment.D. The noise from heavy machinery.9.What is the researchers’ concern over the increase of birds’ song output?A. The environment might be polluted.B.The people’s hearing might be affected.C. The industry cost might be increased.D. The birds’ health might be damaged.10.What does the underlined word“nocturnal”in Paragraph 5 mean?A. Active at night.B. Inactive at night.C. Active during the day.D. Inactive during the day.11.Why do some birds thrive in noisy environments?A. Because there are fewer dangers.B. Because there is more food to eat.C. Because there is less light pollution.D. Because there are more places to takeshelter.DBy now, we are all aware that social media has had a tremendous influence on our culture, in business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friends’ new baby on Facebook, or reading about Justin Bieber’s latest conflict with the law on Twitter, what are some of the real influences?Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choice. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills.Unfortunately there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.Also, what you carelessly post on the Net can come back to trouble you. Revealing(泄露) personal information on social sites can make users vulnerable(易受伤害的)to crimes like identity theft, stalking, etc. Many companies perform a background check on the Web before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.Social media has its advantages and drawbacks as each coin has two sides. It isup to each user to use social sites wisely to enhance their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.12. Paragraph 2 mainly shows that social networks _________.A. help students finish their homeworkB. offer professionals good chancesC. benefit users in various waysD. guide users to make right choices13. Faced with problems caused by social media, some companies ________.A. forbid the use of social networks during work timeB. avoid posting embarrassing informationC. refuse to hire potential addicted employeesD. take legal action against the attackers14. The main purpose of this passage is to _________.A. share experiences in using social mediaB. remind people to wisely use social mediaC. provide some advice on social problemsD. raise public awareness of social problems15. Which of the following shows the development of ideas in this passage?(P---point; Sp---sub-point;C---conclusion)A. B.C. D.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

一、现代文阅读(36分)(一)论述类文本阅读(本题共3小题,9分)阅读下面的文字,完成下面小题。
中华文明复兴是当代中国发展的核心问题,而传承、创新和引领则是中华文明复兴的要义。
复兴的前提是传承,但传承不等于复古。
东西方文明兴衰的规律表明,文明复兴的过程必然是文明再造的过程,文明唯有再造,方可复兴。
文明的再造,是对传统文明扬弃更新的过程,既是对传统文明优秀成分的继承和升华,又须摆脱传统文明糟粕成分的禁锢和束缚。
在人类历史上,成功的文明复兴都是优化或革新传统文明而结出的甜美果实。
中华文明的复兴也不例外。
所谓“梦回唐朝”,为再现昔日荣光而回归强大的封建帝国,既不可能也不必要。
没有优秀文明传统的复现也不是复兴。
一种文明的复兴不能变成对当下强势文明的简单模仿。
舍弃自身文明的优秀传统,复制外来文明,只能让自己成为其他文明的附庸而丧失复兴的可能。
虽然在理论上很容易明白这个道理,但在实践中却极易陷入这一泥潭而不自知。
近代以来,面对西方的挑战,改良者不仅以西方文明为圭臬,而且卷入西方主导的思维模式中,在不知不觉中消解了中华文明的主体性。
一味以当下的强势文明作为模板去追赶,而不加以批判性反思和超越,根本无法实现中华文明伟大复兴。
因此,中华文明的复兴也意味着挣脱西方文明的羁绊,重建中华文明自信。
在新时代条件下,对西方文明加以创造性转化和创新性发展,也是中华文明复兴的应有之义。
文明的复兴是复现与新兴的统一。
二者相互依存,缺少任何一方都不能构成复兴。
但相比之下,后者是文明复兴更为本质的方面。
没有文明的自我创新,中华民族就不能浴火重生。
中华文明的复兴,是以文明的创新作为基本内涵的。
无论是对传统文明的再造,还是对西方文明的扬弃,指向的都是文明的创新,都是在传统文明和西方文明基础上建构新的文明。
中华文明复兴,不只是经济总量这种硬实力的复兴,也不只是硬实力加软实力的复兴,甚至也不只是文明名次跃居榜首,而更在于创造出较之现今主导文明更益于人类生存和发展的更为优越和高级的新型文明。
第一部分阅读理解(共两节,20小题,每小题2分,满分40分)第一节阅读下面短文,从每题所给的四个选项(A、B、C、D )中,选出最佳选项。
(共15小题,每小题2分,共30分)AGreat Activities for Nature LoversHikingOne of the easiest and most accessible ways to get close to nature is by setting out on a good old fashioned hike. Hikin g generally doesn’t require any fancy equipment or special skills, just a piece of map and a thirst for adventure. This activity can be as relaxing as you make it.Backcountry CampingWhy limit yourself to just a day hike when you can have a full weekend or longer adventure?Backcountry Camping involves packing your tent, sleeping gear, food, and water on your back to set up camp in a remote location. If you’re an experienced hiker and camper,this is an excellent way to test your survival skills and explore the wilderness.Mountain and Road BikingUnlike long hikes through the woods, biking allows you to cover more ground and travel farther in nature. Mountain biking typically involves riding up and down steep slopes, between trees, and over rocks. If this sounds too intense or your tires aren’t suited for rugged terrain (地形), consider taking a road bike on paved trails through forest preserves or along country roads.GardeningContrary to popular belief, you don’t have to travel beyond your own backyard to experience the beauty of nature every day. If your personality is less adventurous or your mobility is restricted, consider planting a garden to grow your own vegetables, fruits, herbs, or flowers. There’s something truly satisfying about mixin g up a salad with fresh ingredients you grew yourself. One of the best parts about spending time in nature is that it doesn’t have to break your budget and anyone can do it.1.What does hiking need for hikers?A. A world map.B. A strong desire.C. Practical skills.D. Necessary equipment.2.Where will you go to show your survival potential in the wild?A. To a backyard.B. To a forest.C. To a mountain.D. To a distant place.3.What is the advantage of enjoying the natural beauty in your garden?A. It’s popular.B. It saves money.C. It’s adventurous.D. It saves time.BAudio digital (有声数字化)books are becoming more and more popular these years. One of the reasons for this is that audio digital b ooks can be “read” in many places comfortably.The first favorite place for many people is in bed, before going to sleep. There are nights when a person would want to do nothing but lie in bed going over what has happened in the day. Many people like to just lie in bed in the dark before they fall asleep at night. This would be the perfect time to listen to an audio digital book. If you read an ordinary book, the lights have tobe turned on and you have to turn the pages with your hand. An audio book can just be listened to while a person stays comfortably in bed.The next favorite place to listen to audio digital books would be in the kitchen. For some people kitchen work is boring. Audio digital books provide good entertainment, and people don’t need t o turn pages.An audio digital book is a favorite while a person is gardening. They can help take a person’s mind off job at hand. It can be fun and exciting to do gardening with the help of these books. Another great place would be while exercising. It allows the mind to be free while the legs, body and arms are kept busy. This would be a great place to listen to these books.The next favorite place would be while we are on the road to and from work on buses, trains or even on long flights. Audio digital books have become good companions and help us relaxed.4.What does the second paragraph mainly tells us?A. A favorite place to listen to audio digital books is in bed.B. It’s the perfect time to listen to an audio digital book at noon.C. You can listen to an audio digital book comfortably at home.D. You have to keep the lights on while reading ordinary books.5.Why do some people like listening to audio digital books in the kitchen?A. The kitchen is the best place to do this.B. It can help them avoid boredom.C. They can sing to the music.D. It can save power.6.Why does a person “read” an audio digital book while exercising?A. To lose weight easily.B. To keep his body busy.C. To relax his mind.D. To reduce pain quickly.7.Where does the text probably come from?A. An announcement.B. A book review.C. A guidebook.D. A science magazine.CIt used to be mostly the army that used small, unpiloted aircraft, called “drones”. The little planes were very costly. But as they have dropped in price, more people have begun to use them.The fast rate of development of computer technology, image sensing equipment, satellite navigation and smart phones has led to lower-priced drones. Researchers and developers have learned how to build smaller and less costly drones. Nowadays, moviemakers are using drones to film from the sky. Historians use them when they explore ancient buildings. Rescue workers use them to look for people. And now farmers are also using them to watch over their crops. Romain Faroux is a French businessman, whose father was a farmer. He believed drones could help farmers. He has helped create a company which has developed a small drone that could be controlled by people on the ground. It's called “Agridrone”. It uses a special sensor to examine crops. The technology used on the drone is similar to that used on a smart phone—except it has wings. A computer program directs the drone to fly over the crops. The sensor on the drone records four different-colored “bands” of sunlight that are reflected off the crops.Jean-Baptiste Bruggeman is another farmer in France who is using a drone. He says the drone flies over his crops at different times of the season and provides a lot of informationabout his crops. The pictures taken by the drone show him the exact amount of fertilizer the crops need. It also shows exactly where the fertilizer is needed.Romain Faroux says farmers use information provided by the Agridrone to place fertilizer only in areas where it is needed. This saves money and reduces pollution. Before they used the drones, farmers would put the same amount of fertilizer everywhere. Drones also save time because farmers can examine up to three hectares (英亩) in about a minute.8.Why do rescue workers and farmers begin to use drones?A. Because they are affordable now.B. Because their sizes have become smaller.C. Because they can save people a lot of time.D. Because the technology has been developed.9.What is the sensor on the drone mainly used for?A.Helping the sunlight shine on the crops.B. Directing the wings to fly over the crops.C. Examining the different colors of the crops.D. R ecording the sunlight “bands” reflected off the crops.10.What does the underlined word “it” in paragraph 3 probably refer to?A. A smart phone.B. A sensor.C. A drone.D. A band.11.What is the main idea of the text?A. Crops will be harvested by drones soon.B. Drones will be widely used in different fields.C. French farmers use drones to examine their crops.D. Farmers develop special drones for their crops.DPassenger pigeons(旅鸽) once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks so large that they darkened the sky for hours.It was calculated that when its population reached its highest point, there were more than 3 billion passenger pigeons—a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant bird in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were most abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered(驱散) the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birdssurvived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden on September 1,1914.12.In the 18th and early 19th centuries, passenger pigeons _______.A. were the biggest bird in the worldB. lived mainly in the south of AmericaC. did great harm to the natural environmentD. were the largest population in the US13.The underlined word “undoing” probably refers to the pigeons’ _______.A. escapeB. ruinC. liberationD. evolution14.What was the main reason for people to kill passenger pigeons?A. To seek pleasure.B. To save other birds.C. To make money.D. To protect crops.15.What can we infer about the law passed in Michigan?A. It was ignored by the public.B. It was declared too late.C. It was unfair.D. It was strict.第二节(共5小题,每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。

ANew Scientist EventInstant Expert— How Your Brain WorksSaturday, 20 May 2017 from 10:00 to 17:00London, United KingdomEver wondered how your brain works? How that stuff in your head enables you to see, hear and think about the world around you, make decisions and act on them? Join six leading scientists to explore what we know about the most difficult kilo of matter in the universe.The day will be chaired by psychologist and presenter of BBC Radio 4’s All in the mind,Claudia Hammond.Overview:The brain has long been a source of fascination. In 1819, the radical(激进的)thinker and surgeon William Lawrence put it like this: It’s strong ly suspected that a Newton or Shakespeare excels other men only ... by having an extra inch of brain in the right place.Today, many such suspicions are certainties. This event will introduce you to the evolution of the brain. We’ll study technique for co ntrolling the brain using electric and magnetic fields, as well as the latest technologies that follow you to control the outside world using your mind alone.Topics covered will include:Evolution of the brainHow memory makes us humanEmotionSleep and brainBooking information:The event will be held in Brunei Auditorium at RCGP/30 Euston Square. And doors to theAuditorium will open at 9:15 am.We require the name of each person attending — please ensure this is provided at the time of booking.The schedule for the day will be confirmed closer to the event, and will be emailed to all ticket holders.A minimum of 100 early bird discounted tickets are available priced at £129 (saving £20 on the full ticket price of £149).1. What can attendees learn from the event?A. How much their brain weighs.B. How their sleep is related to their brainC. Whether they can act on decisions they made.D. How their brain is controlled by electric and magnetic fields.2. What can we infer from what William Lawrence said?1A. There will be no another Newton or Shakespeare.B. The brain of a Newton or Shakespeare is different from that of others'.C. The more you use your brain, the more intelligent you will be.D. No one can explain why people like Newton and Shakespeare are more intelligent than others.3. When people book tickets, they are _____ .A. required to offer their email addressB. likely to be told the schedule for the eventC. required to decide when to enter the AuditoriumD. likely to enjoy a discount if they promise to come to the event earlyBAre you taking a summer vacation this year? If you are, have you already started preparing for your trip? Online, there are a large number of preparation tips available for summer travelers. While preparation advice and tips may be of assistance to you, they are often hard to go by. This is because not everyone spends vacations at the same location.No matter what your vacation destination is, you will need to take the climate into consideration. If you are visiting a tropical location, you will need to bring along the appropriate clothing. While you may be expecting warm and sunny weather, it is still advised that you prepare for the worst. Raincoats and an umbrella may be a great addition to your summer clothing.Perhaps, the most popular summer vacation destination is the beach. Each year millions of individuals and families flock to beaches. When vacationing at the beach, it is important that you bring along proper clothing and sunscreen. Many vacationers do not realize the dangers of sunbathing without sunscreen. In addition to sunscreen, you will need to make sure that you have beach towels and plenty of water on hand.For the most part, if you forget to bring along certain supplies you can purchase replacements. Many popular vacation destinations have inflated prices. To prevent unnecessary expenses, you are encouraged to check your luggage before you leave. In addition to the above mentioned preparation tips, you must inform friends and family of where you are going. In case something happens back home, you can easily be reached.4. In the passage the author intends to _____A. give advice on how to prepare for vacationB. make a plan for his summer vacationC. share his experience about summer vacationD. warn readers against cheaters during vacation5. As for the preparation advice and tips online, _____.A. they are useful as well as practicalB. they are designed to cheat travelersC. they may make you puzzled in a wayD. they can include all the destinations6. If you travel to a tropical country, _____.A. you must consider the climate firstB. you should wear shorts and T-shirtsC. you must prepare proper clothesD. you should expect the sunny weather7. According to the passage we can know that _____.A. vacationing at the beach is the first but oneB. vacationers on beach are at the risk of sunburnC. you must drink plenty of water before going to beachD. you have to stay outdoors when going campingCHave your parents ever inspected your room to see if you cleaned it properly?Imagine having your entire house,garage,and yard inspected at any time―with no warning.Inspections were a regular part of lighthouse(灯2塔)living,and a keeper’s reputation depended on the results.A few times each year,an inspector arrived to look over the entire light station.The inspections were supposed to be a surprise,but keepers sometimes had advance notice. Once lighthouses had telephones,keepers would call each other to warn that the inspector was approaching.After boats began flying special flags noting the inspector was aboard,the keeper’s family made it a game to see who could notice the boat first.As soon as someone spotted the boat,everyone would do last-minute tidying and change into fancy clothes.The keeper then scurried to put on his dress uniform and cap.Children of keepers remember inspectors wearing white gloves to run their fingers over door frames and windowsills looking for dust. Despite the serious nature of inspections,they resulted in some funny moments.Betty Byrnes remembered when her mother did not have time to wash all the dishes before an inspection.At the time,people did not have dishwashers in their homes.In an effort to clean up quickly,Mrs.Byrnes tossed all the dishes into a big bread pan,covered them with a cloth,and stuck them in the oven.If the inspector opened the oven door,it would look like bread was baking.He never did.One day,Glenn Furst’s mother put oil on the kitchen floor just before the inspector entered their house.Like floor wax,the oil made the floors shiny and helped protect the wood.This time,though,she used a little too much oil.When the inspector extended his hand to greet Glenn’s mother,he slipped on the freshly oiled surface.“He came across that floor waving his arms like a young bird attempting its first flight,”Glenn later wrote.After he steadied himself,he shook Glenn’s mother’s hand,and the inspection continued as though nothing had happened.8.What does Paragraph 1 tell us about the inspection at the light station?A. It was carried out once a year.B. It was often announced in advance.C. It was important for the keeper’s fame.D. It was focused on the garage and yard.9.The family began making preparations immediately after .A. one of the members saw the boatB. a warning call reached the lighthouseC. the keeper put on the dress uniform and capD. the inspector flew special flags in the distance10.If the inspector had opened the oven door,he would have seen .A. an empty panB. many clean dishesC. pieces of baked breadD. a cloth covering something11.The inspector waved his arms .A. to try his best to keep steadyB. to show his satisfaction with the floorC. to extend a warm greeting to Glenn’s motherD. to express his intention to continue the inspectionDThe twentieth century saw greater changes than any century before: changes for the better, changes for the worse; changes that brought a lot of benefits to human beings, changes that put man in danger. Many things caused the changes, but, in my opinion, the most important was the progress in science.Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure of matter and of the universe; it has brought us a better understanding of the nature of life and of its continuous development. Technology in the application of science has made big advances that have benefited us in nearly every part of life.3The continuation of such activities in the twenty-first century will result in even greater advantages to human beings: in pure science — a wider and deeper knowledge in all fields of learning; in applied science — a more reasonable sharing of material benefits, and better protection of the environment.Sadly, however, there is another side to the picture. The creativity of science has been employed in doing damage to mankind. The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons. Although their actual use has so far occurred only in the Second World War, the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used, the result could have been the ruin of the human race, as well as of many kinds of animals.William Shakespeare said, “The web o f our life is of a mingled yarn (纱线), good and ill together.” The above brief review of the application of only one part of human activities—science seems to prove what Shakespeare said. But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war?12.What is the main idea of the whole passage?A.The potential use of nuclear weapons.B.The development of science is a double-edged sword.C.The progress in the development of science.D.A real concern—must the ill go hand in hand with the good in the development of science?13.

ANew Scientist EventInstant Expert— How Your Brain WorksSaturday, 20 May 2017 from 10:00 to 17:00London, United KingdomEver wondered how your brain works? How that stuff in your head enables you to see, hear and think about the world around you, make decisions and act on them? Join six leading scientists to explore what we know about the most difficult kilo of matter in the universe.The day will be chaired by psychologist and presenter of BBC Radio 4’s All in the mind,Claudia Hammond.Overview:The brain has long been a source of fascination. In 1819, the radical(激进的)thinker and surgeon William Lawrence put it like this: It’s strongly suspected that a Newton or Shakespeare excels other men only ... by having an extra inch of brain in the right place.Today, many such suspicions are certainties. This event will introduce you to the evolution of the brain. We’ll study technique for controlling the brain using electric and magnetic fields, as well as the latest technologies that follow you to control the outside world using your mind alone.Topics covered will include:Evolution of the brainHow memory makes us humanEmotionSleep and brainBooking information:The event will be held in Brunei Auditorium at RCGP/30 Euston Square. And doors to the Auditorium will open at 9:15 am.We require the name of each person attending — please ensure this is provided at the time of booking.The schedule for the day will be confirmed closer to the event, and will be emailed to all ticket holders.A minimum of 100 early bird discounted tickets are available priced at £129 (saving £20 on the full ticket price of £149).1. What can attendees learn from the event?A. How much their brain weighs.B. How their sleep is related to their brainC. Whether they can act on decisions they made.D. How their brain is controlled by electric and magnetic fields.2. What can we infer from what William Lawrence said?A. There will be no another Newton or Shakespeare.B. The brain of a Newton or Shakespeare is different from that of others'.C. The more you use your brain, the more intelligent you will be.D. No one can explain why people like Newton and Shakespeare are more intelligent than others.3. When people book tickets, they are _____ .A. required to offer their email addressB. likely to be told the schedule for the eventC. required to decide when to enter the AuditoriumD. likely to enjoy a discount if they promise to come to the event earlyBAre you taking a summer vacation this year? If you are, have you already started preparing for your trip? Online, there are a large number of preparation tips available for summer travelers. While preparation advice and tips may be of assistance to you, they are often hard to go by. This is because not everyone spends vacations at the same location.No matter what your vacation destination is, you will need to take the climate into consideration. If you are visiting a tropical location, you will need to bring along the appropriate clothing. While you may be expecting warm and sunny weather, it is still advised that you prepare for the worst. Raincoats and an umbrella may be a great addition to your summer clothing.Perhaps, the most popular summer vacation destination is the beach. Each year millions of individuals and families flock to beaches. When vacationing at the beach, it is important that you bring along proper clothing and sunscreen. Many vacationers do not realize the dangers of sunbathing without sunscreen. In addition to sunscreen, you will need to make sure that you have beach towels and plenty of water on hand.For the most part, if you forget to bring along certain supplies you can purchase replacements. Many popular vacation destinations have inflated prices. To prevent unnecessary expenses, you are encouraged to check your luggage before you leave. In addition to the above mentioned preparation tips, you must inform friends and family of where you are going. In case something happens back home, you can easily be reached.4. In the passage the author intends to _____A. give advice on how to prepare for vacationB. make a plan for his summer vacationC. share his experience about summer vacationD. warn readers against cheaters during vacation5. As for the preparation advice and tips online, _____.A. they are useful as well as practicalB. they are designed to cheat travelersC. they may make you puzzled in a wayD. they can include all the destinations6. If you travel to a tropical country, _____.A. you must consider the climate firstB. you should wear shorts and T-shirtsC. you must prepare proper clothesD. you should expect the sunny weather7. According to the passage we can know that _____.A. vacationing at the beach is the first but oneB. vacationers on beach are at the risk of sunburnC. you must drink plenty of water before going to beachD. you have to stay outdoors when going campingCHave your parents ever inspected your room to see if you cleaned it properly?Imagine having your entire house,garage,and yard inspected at any time―with no warning.Inspections were a regular part of lighthouse(灯塔)living,and a keeper’s reputation depended on the results.A few times each year,an inspector arrived to look over the entire light station.The inspections were supposed to be a surprise,but keepers sometimes had advance notice.Once lighthouses had telephones,keepers would call each other to warn that the inspector was approaching.After boats began flying special flags noting the inspector was aboard,thekeeper’s family made it a game to see who could notice the boat first.As soon as someone spotted the boat,everyone would do last-minute tidying and change into fancy clothes.The keeper then scurried to put on his dress uniform and cap.Children of keepers remember inspectors wearing white gloves to run their fingers over door frames and windowsills looking for dust.Despite the serious nature of inspections,they resulted in some funny moments.Betty Byrnes remembered when her mother did not have time to wash all the dishes before an inspection.At the time,people did not have dishwashers in their homes.In an effort to clean up quickly,Mrs.Byrnes tossed all the dishes into a big bread pan,covered them with a cloth,and stuck them in the oven.If the inspector opened the oven door,it would look like bread was baking.He never did.One day,Glenn Furst’s mother put oil on the kitchen floor just before the inspector entered their house.Like floor wax,the oil made the floors shiny and helped protect the wood.This time,though,she used a little too much oil.When the inspector extended his hand to greet Glenn’s mother,he slipped on the freshly oiled surface.“He came across that floor waving his arms like a young bird attempting its first flight,”Glenn later wrote.After he steadied himself,he shook Glenn’s mother’s hand,and the inspection continued as though nothing had happened.8.What does Paragraph 1 tell us about the inspection at the light station?A. It was carried out once a year.B. It was often announced in advance.C. It was important for the keeper’s fame.D. It was focused on the garage and yard.9.The family began making preparations immediately after .A. one of the members saw the boatB. a warning call reached the lighthouseC. the keeper put on the dress uniform and capD. the inspector flew special flags in the distance10.If the inspector had opened the oven door,he would have seen .A. an empty panB. many clean dishesC. pieces of baked breadD. a cloth covering something11.The inspector waved his arms .A. to try his best to keep steadyB. to show his satisfaction with the floorC. to extend a warm greeting to Glenn’s motherD. to express his intention to continuethe inspectionDThe twentieth century saw greater changes than any century before: changes for the better, changes for the worse; changes that brought a lot of benefits to human beings, changes that put man in danger. Many things caused the changes, but, in my opinion, the most important was the progress in science.Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure of matter and of the universe; it has brought us a better understanding of the nature of life and of its continuous development. Technology in the application of science has made big advances that have benefited us in nearly every part of life.The continuation of such activities in the twenty-first century will result in even greater advantages to human beings: in pure science —a wider and deeper knowledge in all fields of learning; in applied science — a more reasonable sharing of material benefits, and better protection of the environment.Sadly, however, there is another side to the picture. The creativity of science has been employed in doing damage to mankind. The application of science and technology to thedevelopment and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons. Although their actual use has so far occurred only in the Second World War, the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used, the result could have been the ruin of the human race, as well as of many kinds of animals.William Shakespeare said, “The web of our life is of a mingled yarn (纱线), good and ill together.” The above brief review of the application of only one part of human activities—science seems to prove what Shakespeare said. But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war?12.What is the main idea of the whole passage?A.The potential use of nuclear weapons.B.The development of science is a double-edged sword.C.The progress in the development of science.D.A real concern—must the ill go hand in hand with the good in the development ofscience?13. From the fourth paragraph, we can infer that________.A. a great many nuclear weapons were actually used for warB. a large number of nuclear weapons should have been used for warC. the author is anxious about the huge number of nuclear weapons on the earthD. the author is doubtful about the ruin of human beings by nuclear weapons14. The underlined word “mingled” in the last paragraph most probably means________.A. mixedB. fixedC. doubleD. thick1 5. What do you think the author is most likely to suggest if he continues to write?A. Further application of science to war.B. More reading of William Shakespeare.C.
