In 1973 third generation beekeeper Philip ; Cropp set up NelsonHoney & Marketing. His passion for bees, the many wonderful products they produce, have seen Nelson Honey grow from humble beginnings to a hugely successful company with a growing range of honey products sought after worldwide.Philip's “Honey will fix it” approach is legendary among friends, neighbors and customers and has been the driver behind some of the revolutionary products he developed over the years like Nectar Ease and Royal Nectar.Nutrition is all about our honeys. Manuka Honey, sourced from the Marlborough Sounds, Kahurangi National Park and throughout the top of New Zealand's South Island; West Coast Honey, a delicious multi-floral honey also described as the fruit bowl of honeys comes from the pristine（原始状态的）West Coast of the South Islands; and finally Honeydew Honey which comes from the Beech forests of the Nelson Lakes areas. All our honeys are great as a food and may offer added benefits.Health covers a range of different products, aimed at helping you feel great and stay healthy. Nectar Ease is our sought after Manuka Honey with added Bee Venom range. In this range you'll also find Propolis, Pollen, Manuka Oil and Apple Cider Vinegar with added Manuka Honey.Finally our Skincare range is where you will find a range of Manuka Honey soaps as well as our world-famous Royal Nectar products; anything from the Original Face Mask to the new gift packs.To read more about how it all started, check out the About Us section, or go straight to Products to order your own goodies.56. Which of the following is true according to the passage?A. Royal Nectar is a very popular product around the world.B. Nectar Ease is ideal especially for people with skin problems.C. West Coast Honey comes from the Nelson Lakes areas.D. Nelson Honey & Marketing was set up over 100 years ago.57. What is the main purpose of this article?A. To introduce Nelson Honey & Marketing.B. To analyze the benefits of honey products.C. To promote products from Nelson Honey & Marketing.D. To attract readers to visit cities in New ZealandBHalf a century ago, Japan built the world's first high-speed rail network-a network that remains the gold standard in train travel today. Currently the county is now helping Texas build its own bullet train, a potential game-changer for transportation in the stale.When it launched on October l, 1964, the world's first high-speed rail network was known as the “super-express of dreams." The first line in Japan's now world-famous shinkansen network was built against all odds, in the face of fierce public opposition, technical difficulties and astronomical costs -Half a century ago, the system was far humbler. In 1964, the first track was a 320-mile-long link between Tokyo and Osaka that reduced the trip from six-and-a-half hours (on conventional trains) to three hours and 10 minutes, traveling at a maximum speed of 200 miles per hour. For the first time, workers could get to meetings in one city during the day and be back home drinking a beer in the local pub that night.Not only did the train expand mobility profoundly, but also businesses appeared around the major stops as a growing emphasis on productivity swept across Japan. Today, the shinkansen network has 1,487 miles of track, with more set to open in the coming years. It seems that everything the shinkansen touches turns to city, and regions that are off the beaten track, so to speak, benefit greatly from the economic jumpstart brought by the train. New shinkansen lines are often proceeded by aggressive marketing campaigns promoting tourism in those areas, a strategy that seems to work.Despite its astronomical costs, it actually has saved more. Today, over 350,000 annual trips transport tens of millions of passengers all over Japan with efficiency—the average delay time is less than a minute.A research report titled 30 Years of High-Speed Railways: Features and Economic and Social Effects of The Shinkansen by Hiroshi Okada, estimates that the economic impact from the shinkansen train network, based on the time saved from faster travel, is approximately ¥500 billion ($4.8 billion USD) per year. Okada stresses that the cultural impact is also significant, a shinkansen offers people living far from urban centers "easy access to concerts, exhibitions, theaters, etc., enabling them to lead fuller lives." .Japan has a plan, known as the One-Day Travel Initiative. Its goal: regardless of where you are in Japan, it should only take you three hours to get to the nearest major regional city (Tokyo. Osaka, Nagoya,Sapporo or Fukuoka). The planned impact of this hyper-mobility is to discourage the tide of migration toward urban centers, like Tokyo, and encourage decentralization.58. What can we learn about Shinkansen network from the passage?A. It didn't change people's life much.B. It was built despite many difficulties.C. It has little effect on economy and culture.D. It was not worth the money despite its benefits.59. According to Okada, what cultural impact does a shinkansen have on people living far from urban centers?A. Accumulating vast wealth.B. Saving more travelling time.C. Creating massive employment.D. Enjoying a more colorful life.60. What is the main purpose of the One-Day Travel Initiative?A. To include more citizens in urban centers.B. To advocate urban lifestyle among migrants.C. To promote reasonable distribution of population.D. To satisfy the increasing needs of urban centers.CHave you been told you have penicillin allergy（过敏）? Did your parents tell you that you had a reaction as an infant or child, so you should never take it again? Has it been so long since you had a reaction to penicillin that you don't remember what happened? If you fit any of these descriptions or are just not sure if you have penicillin allergy, there's good news for you: Chances are that you probably don’t have.Between 10 to 20 percent of Americans believe they have a penicillin allergy, but a recent study at Mayo Clinic found that only 10 percent of those people are truly penicillin allergic. In other words, 9 out of 10 people who think they have penicillin allergy are avoiding it for no reason. Even in people with documented allergy to penicillin, only about 20 percent are still allergic 10 years after their initial allergic reaction. It’s not necessarily a permanent condition.Why is this important? Aren’t there many other antibiotics you can use if you have penicil lin allergy? Penicillin has been around since 1928. Penicillin and its related medicines include amoxicillin, methicillin and amoxicillin-clavulnate. These medicines are highly effective treatments for many bacterial infections, such as strep throat and ear infection. Of course, there are alternative antibiotics, but these arc often much more expensive and carry a higher risk of side effects because these alternative antibiotics are broad-spectrum, meaning they fight many types of bacteria, both good and bad. That can lead to development of drug-resistant bacteria, or deadly “superbugs” . This increases the risk for all of us in the future of not having an effective antibiotic to treat our infection.How do you find out if you have penicillin allergy? Board-certified allergists can test you. First, the allergist will get a history from you about your possible allergy. Typical questions include: How long ago did you have the reaction? What type of reaction occurred, and how soon after you took the penicillin did the reaction appear? The testing is done on the forearm by pricking the skin with a needle. If the results are negative and there is no reaction, penicillin will be injected in the skin. These tests are not painful, and results are available in 15 minutes. A positive reaction may lead to some swelling and itching where the test was placed, which usually goes away within an hour.In very rare cases, an allergic reaction occurs. This can include hives, swelling, wheezing and/or difficulty breathing. The allergist is trained to treat this rare condition quickly if it happens. If all skin testing is negative, you may be given an oral dose of penicillin in the office. The oral drug challenge is used to verify that you don't have penicillin allergy. Usually, you'll be observed in the office for 30 minutes to make sure you have no problems.If you find out you don't have a penicillin alle rgy, notify your physicians that it’s now safe for you to take penicillin. They can take “penicillin allergy" off your chart for good!61. What are the questions in the first paragraph used for?A. To ask for other's help.B. To introduce the topic of the passage.C. To share the writer's opinion.D. To summarize the main idea.62. Which is NOT the drawback of the alternative antibiotics?A. They can treat many bacterial infections.B. They cost much more than penicillin.C. They can result in drug-resistant bacteria.D. They also fight good bacteria when used.63. If you have a positive reaction in skin tests, __________.A. you'll be given an oral dose of penicillinB. your skin is sure to swell and itchC. it is not safe for you to take penicillinD. you can't leave the office within an hour64. Which can replace the underlined word “verify”?A. swear.B. admit.C. e xamine.D. confirm.DThe first time she saw Bryce Loski, she flipped. The first time he saw Juli Baker, he ran. For six years of living close by, they had played the same game of cat-and-mouse (Juli was the cat; Bryce was the unfortunate mouse).For years Juli dreamed of one thing: her first kiss from the boy. Nothing else seemed to matter. But when Juli's favorite sycamore tree is threatened by developers, things begin to change. She begins to see things and places and people in a different light. Things, for years, she thought to be important, become things she can live without; and people she thought to be the center of her universe, become nothing more than a star in a faraway galaxy.Things begin changing with Bryce also. It all begins with the eggs...which then cause a domino effect of changes with his relationships with his best friend, his father, the Bakers and, ultimately, Juli.I had seen this book on the shelf at bookstores for years, but never bothered to pick it up because it looked to be another book from Jerry Spinelli (not exactly my favorite author in the world) and so, continually, I would walk past it without giving it a second glance. If by chance I had picked it up, I most likely would not have read it, since the summary on the back didn't seem too appealing. It wasn't until a couple of weeks ago that I heard about Flipped the movie. I read an interview with Callan McAuliffe (the actor who portrays Bryce) and thought that Flipped was a romance right up my alley; cute, innocent and as far from Jane Austin as you could pet. After reading the interview and a summary of the movie, I found the plot-line to be somewhat appealing and a definite breath of fresh air opposed to the dark material I have been recently reading and writing. I found the book a few days later in a Goodwill bookstore and finished it in three days.The story isn’t what you would consider deep.. .it isn't shallow and pointless either…I guess you could say it’s the perfect balance of life-lessons and innocence.You read about Bryce and Juli (each from their own points of view) and how, throughout six years, their lives and views and opinions change and develop. Flipped is somewhat of a coming of age story about two kids learning to see life from the other’s point of view and learning that growing up isn't about staying the same, but changing; changing likes and dislikes; changing friends and crushes and views on family.Uniquely written, every other chapter showing the same scenes and events, only from the other's point of view, you see how the saying. "Two sides to every story,” is true. You are able to see both Juli and Bryce's reasons for doing what they do and saying what they say...not just what the other sees.It will be interesting to see how this writing style comes into play in the movie. Overall I thought this story was incredibly cute and light-hearted, although it didn’t entirely meet my expectations. Especially the ending. I felt as though it ended quite abruptly and that there was more story that needed to be told.But even with that, after having taken a step back and taken my mind off of Flipped, I find the story has stuck with me and stayed in the back of my mind, making me highly anticipate seeing this book turned to a film. I understand why it has been so popular for almost two decades and am looking forward to seeing Flipped on the big screen soon.65. According to Paragraphs 1 and 2, what is the relationship between Juli Baker and Bryce Loski?A. A couple.B. Sister and brother.C. Daughter and father.D. Neighbors.66. What has happened to Juli after her favorite sycamore tree is endangered?A. Things and people around her have changed beyond recognitionB. She has come to realize Bryce is the center of her universe.C. Bryce Loski has become an insignificant figure in her lifeD. The sycamore tree is more than a star in faraway galaxy67. Which of the following sentences best expresses the essential information in the underlined sentence in Paragraph 4?A. It was the interview with Callan that made the author realize that it was a book to his taste.B. After reading the interview, the author was deeply impressed by his story of romance.C. It was the performance of Callan that inspired author to read the original work.D. After reading the interview with Callan, the author confirmed his previous attitude to Flipped68. According to Paragraph 6, what is the theme of Flipped?A. Changing lifestyles.B. Changing points of views.C. Generation gap.D. Forever love.69. In the author’s opinion, it’s somewhat disappointing that Flipped doesn’t provide readers with_______.A. a smooth ending to the whole storyB. limited appeal for re-appreciationC. much space for individual imaginationD. a happy ending for Juli and Bryce70. The passage is mainly about____________.A. a beautiful love story between Juli Baker and Bryce LoskiB. how a summary prevents readers from moving forwardC. a cute and innocent love story that you shouldn’t missD. how an amazing movie was adapted from a love story五、任务型阅读10X1’Music is a Universal Language“Music is the universal language of mankind,” - Henry LongfellowEveryone has the inborn ability to understand and enjoy music. There are many theories to why this is, but it has become a part of human beings. Since the beginning, humans have expressed themselves through music. Simple tribal rhythms evolved into many types of m complex music, including classical, rock, jazz, and R&B. While the styles between these many types of music may vary, everyone is able to understand and relate to them.What are the essential parts of a language? Every language uses vocabulary, or a set of words, to create sentences that convey messages. The tone and style of the sentences convey different feelings or emotions. Music is exactly the same way. Twelve tones, or notes, are combined to create phrases that also convey emotion. Music can even be written, like other languages. Conversations even take place in music. Two saxophonists can play melodic back and forth, expressing different styles and feelings, building off of each other, responding to each other. Music changes over the years like other languages. Most people who speak fluent English cannot read one of Shakespeare’s plays because the language has changed so much. Music is also affected by time, and over a long period, many new types of music and instruments have emerged to create different sounds and convey different messages. There are so many similarities between vocal language and music that they must be same.I recently had a chance to experience conversation through music. In 2008, I traveled to Manila, Philippines to participate in a high school jazz exchange where many students from all over Asia came together to share their talents. Everyone was mixed into different small groups to prepare for a concert at the end of week. Few people spoke fluent English so vocal communication was very tough. However, it wasn't needed. Everyone seemed to understand each other simply through the music and there were few times where direct translation was needed. At the performance, every group played for a live audience. They all sounded phenomenal and it felt like they were in perfect time and harmony. During my group's performance, I was able to improvise with a Korean boy who spoke very little English. But we managed to have a conversation through our instruments, building off each other’s riffs until we were creating our own melody on the fly. It was a great experience.Because of the many similarities that music shares with other languages, it is a very effective way to communicate with others. Music brings us together, connects us with other people, and allows us to express ourselves in ways that are different from speech and writing. It has the ability to convey emotions and messages to the core of people, which is why Henry Longfellow is absolutely correct when he states that “music is the universal language of mankin d.”71._________________ 72. _________________ 73. _________________74. _________________75. _________________7 6. _________________77. _________________78. _________________79. _________________ 80. _________________六、单词填空10X0.5’1.

Since 1980, obesity rates(肥胖率)in children and adults have doubled in 73 countries, making people more worried. And rates are increasing in many other countries. Obesity is increasing faster in children than adults in many nations, including Algeria, Turkey and Jordan, the report said. But the world's weight problem is growing in both rich and poor countries alike. Researchers say an increasing number of people are dying of related health problems in what they called a "disturbing global public health problem."Researchers studied health information from 1980 through 2015. They examined obesity rates, average weight gain in 195 countries. They found that obesity rates are three times greater among youth and young adults in countries like China, Brazil and India. Almost 108 million children and more than 600 million adults were found to be overweight. Egypt had the highest number of overweight adults in 2015. Vietnam had the least. In the same year, the United States had the highest number of overweight children, and Bangladesh had the least.Yet hunger remains a problem in many areas. The United Nations said that almost 800 million people, including 300 million children, go to bed hungry each night. Experts said poor diets and lack of physical activity are mainly to blame for the rising numbers of overweight people.Growing populations have led to rising obesity rates in poor countries. Often, poor people will eat processed(加工的) foods instead of choosing a diet rich in vegetables.The London-based Overseas Development Institute studied the price of food in five countries: Britain, Brazil, China, Mexico and South Korea. It found that the cost of processed foods like ice creamand hamburgers has fallen since 1990. But the cost of fresh fruits and vegetables has gone up.4. What do we know about obesity in the world?A. It is worryingB. It is given no attentionC. It has been successfully solvedD. It is more serious among old people5. Which country has the most overweight children in 2015?A. AmericaB. VietnamC. EgyptD. Bangladesh6. What is one of the reasons why people get overweight?A. HungerB. Poor dietC. Diets with vegetablesD. Eating too much fruit7. Which ofthe following can be the best title for the text?A. It’s Important to Have a Balanced DietB. How Can We Lose Weight and Keep Fit?C. Is It Necessary for Us to Eat Fresh Vegetables?D. Nearly One Third of People in the World Are Overweight.CThe shade of a single tree can provide welcome relief from the hot summer sun. But when that single tree is part of a small forest, it creates a considerable cooling effect. According to a study published today in the Proceedings of the National Academy of Sciences, trees play a big role in keeping our cities cool.According to the study, the right amount of tree cover can lower summer daytime temperatures by as much as 10 degrees Fahrenheit. And the effect is quite noticeable from neighborhood to neighborhood, even down to the scale of a single city block. “We knew that cities are warmer than the surrounding countryside, but we found that temperatures vary just as much within cities,” says Monica Turner, a professor in the department of Integrative Biology, Wisconsin-Madison University and a co-author of the study.With climate change making extreme heat events more common each summer, city planners are working on how to prepare. Heat waves drive up energy demands and costs and can have big human health impacts. One potentially powerful tool, the study's authors say, are organisms that have been around long before human civilizations could appreciate their leafy benefits. And those trees may be the secret to keeping the places we live livable.Essentially, says Turner, roads, sidewalks and buildings absorb heat from the sun during the day and slowly release that heat at night. Trees, on the other hand, not only shade those surfaces from the sun's rays, they also release water into the air through their leaves, a process that cools things down.To get the maximum benefit of this cooling service, the study found that tree cover must be more than 40 percent. In other words, an aerial picture of a single city block would need to be nearly half-way covered by a leafy green network of branches and leaves.8. What can we infer from Paragraph 2?A. Temperatures in cities mainly depend on their green coverage.B. People living and working in cities must plant trees in summer.C. Cities are warmer than the countryside because they don't have trees.D. An area with more trees can be cooler than the other parts within a city.9. Which of the following problems is caused by extreme heat events?A. Severe damage of city facilities.B. Serious human health problems.C. Residents' growing demands for plants.D. Unnecessary waste of energy resources.10. Why are trees crucial to cities?A. They help shade and cool the cities.B. They make urban scenery beautiful.C. They build up city cooling systems.D. They essentially block and release heat.11. What can city planners conclude from the study?A. They should publish the study in a newspaper.B. They should educate citizens to protect forests.C. They should plant trees on roads and sidewalks.D. They should cover nearly half the city with trees.DSimply being quiet is a growing appeal. Lots of business have appeared to meet a rising demand for quiet time, from silent weekend getaways to silent dining, silent reading parties and even silent dating. Silence can mean different things to different people. We are usually silent only with those closest to us. So there is something almost radical(不同凡响的)about the recent trend towards enjoying silence with strangers.Mariel started a regular silent reading party inDundeejust under a year ago. Readers bring their books and meet in a bar, where they read together in silence for an hour or sometimes two and then put their books away to chat and have a drink. “When the reading party starts, everything goes quiet,” says Mariel, “ It’s a little bit surreal (超现实的), especially in what is usually a noisy bar. However, there is something special about sharing the silence with others. It offers a chance to escape from reality; everyone is so busy with work and with technology being ever present. An event like thisgives people the opportunity to escape these things for a while.”Honi Ryan is an artist based inBerlinwho began hosting silent dinner back in 2006. The rules of the dinner are: no talking, no using your voice, no reading or writing, trying to make as little noise as possible, not connecting with technology, and staying for at least two hours. So far she has taken her silent dinner project toMexico, theUS,AustraliaandChina. “It’s evident that the age-old connections we make over food do not depend on thewords around it. Silence creates the space for the people and places involved to fill with whatever is needed;itis quite different from our usual social behaviors.”12. Why have lots of silent businesses appeared?A. To satisfy people’s demand for silence.B. To make people get close to each other.C. To appeal to young people.D. To change people’s old way of life.13. What can we learn about Mariel’s silent reading parties?A. Readers can use their voice while reading.B. Readers can be busy with their work.C. Readers can connect with technology.D. Readers can chat and drink after reading.14. The underlined word “it” in the last paragraph refers to .A. noiseB. spaceC. silenceD. food15. What can be a suitable title for the text?A. Escape from Reality.B. Enjoying Being Quiet.C. Silent Reading Parties.D. Silent Dining Projects.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。

The medicine that I take for my rheumatoid arthritis causes me to wake up inthe middle of the night with a dry mouth. January 15, 2016, was no different. I, Indiana, US, awoke at 2:30am needing water.I was walking back upstairs from the kitchen when I heard my bulldog , Rock. Whatever Rock was doing down there, it made enough noise for me to go to him. By the time I made it to the bottom of the stairs, he was running up, and he never came up the stairs, no matter what. I think that was his way of telling me, "We've got to go back up. "When I got to the top of the stairs, I turned around and saw a light on, but I didn't remember leaving one on. I walked downstairs again, and that's when I saw fire. I immediately shouted to my wife to wake up and get our three kids. I grabbed a knife and cut out the plastic that covered the window to the porch roof. I then pried open the window and kicked out the screen. I started screaming for help. But help never came. I got everybody out on the roof and threw a blanket out there so we wouldn't slip off. It was cold, January cold. Then I started screaming for help. But help never came.Now, I'm scared of heights and have physical issues, what with my rheumatoid arthritis, but I couldn't let my family burn up. So I jumped off the roof. I didn't scoot to the edge; I just jumped and got the wind knocked out of me when I landed. I found our ladder, placed it against the house, and climbed back up to the roof. I wrapped my arms around my daughter and carried my nine - month - old with my teeth, by his little sleeper. Then I climbed down the ladder. Once on the ground, I had my little girl hold her brother, and I went back up to the roof to get my other daughter. Then I went back up again and got my wife. I tried to get my dog, but he just disappeared in the black smoke. I never saw him alive again,I'm no hero. I'm just an ordinary person who'd help anybody. This happened to be the time when I helped my own family. I live to protect my family. Just likeRock—he lived to protect us.4. What made the author wake up at 2:30am?A. My dog's barkingB. The medicine's effectC. A burning fireD. A noise downstairs5. How did Rock tell the author the danger downstairs?A. He turned on a light downstairs.B. He ran to the author's room upstairs.C. He kept barking and running up to stairs.D. He made some noise at the bottom of the stairs.6. What did the author do after his family all stood on the roof?A. He placed a blanket to keep warm.B. He started screaming for help.C. He jumped off the roof.D. He broke open the window and kicked out the screen7. Which ofthe following best describe the author?A. Courageous and responsibleB. Caring and selfishC. Loyal and braveD. Strong and considerateCAccording to Oxford Dictionaries, morality means: “Principles concerning the distinction between right and wrong or good and bad behavior.” Though morality is a rather subjective subject, there are some principles that are universal across all cultures found by an Oxford University study: “help your family, help your group, return favors, be brave, obey superiors, divide resources fairly, and respect others’ property”. The fact that these morals are found across 60 cultures from around the world demonstrates that morality, though subjective, is the cornerstone of keeping our societies together. Here are some reasons to be moral: without morality, a social life is almost impossible to maintain; having a good reputation and having a clear conscience is psychologically healthy; and most philosophies regard unselfish and principled behavior as important.There is no doubt that without morals, a society cannot function effectively. A confused situation would appear, According to the Society of Morality, “We are social animals, and the actions we take-the things we do and the things we don’t do-have consequences on our environments and on the others around us. As a result, we need to be able to govern our behavior in the near term so as not to injure ourselves or our community in the long term. This system of controlling our actions and our thoughts in order to operate in a community is what we often refer to as morality”. Therefore, we need a set of morals in order to operate within a social circle and a social environment. Acting immoral usually results in being excluded from social activities or being avoided by a society based on laws and cultural standards. Besides acting moral having a sociological need, it also has a psychological basis. Most people are concerned to some extent about their reputation. According to PsyPost, “A lot of economicmodels of human behavior assume that people are only rational (理性的) when they narrowly pursue their own self-interest, but history shows us that people are also tremendously concerned with being and appearing moral”. So, the fear of one’s reputation being damaged is often a strong motivator to be moral. And if someonehas been immoral,most people go out of their way to make sure no one finds out, or to correct the behavior in order to not be caught. This goes in line with conscience as well. People generally feel in a better psychological state if they feel that their conscience is clean. A dirty conscience can result in a lack of sleep, anxiety, internal stress, and even illness.On the side of philosophy, the study of ethics (伦理) comes into play. Most philosophers agree that one should rationally choose a set of standards of behavior in order to function. Though there is moral relativism, there are universal anthropological (人类学的) morals, as mentioned in the introduction. By the nature of our societies and cultures, we choose what we believe is right and wrong. But surprising, this rational behavior comes to a general agreement on morals. So, there is a fine line between moral relativism and moral absolutism. But the main thing to take away from this discussion is that philosophers generally believe that each individual has the right to rationally come up with a set of ethics to live by, and that it is healthy to do so.8. The author discusses morality (paragraph 1) in order to ________.A. explain the relationship between morality and cultureB. describe the moral rules found all around the worldC. contrast the distinction between right and wrongD. introduce the definition, principles and reasons of morality9. It can be inferred from the passage that ________.A. acting moral allows us to fit into group betterB. morality brings the system of controlling behaviorC. contrast the distinction between right and wrongD. introduce the definition, principles and reasons of morality10. Which of the following is the psychological basis for acting moral?A pursuit of self-interest. B. a clean conscience.C. The concern about reputation.D. a dirty conscience.11. What does the author advise us to do according to the last paragraph?A. To reach a general agreement on morals based on ethics.B. to carve one’s own sense of ethics to operate in this world.C. To choose between moral relativism and moral absolutism.D. To exclude philosophers’ beliefs and solution as well.DLast summer, I spent four months working in France, where the company I was working for put me up in a house that didn’t have Wi-Fi. I wasn’t looking forward to it.I soon discovered, however, that living in a house without Wi-Fi was easier than I expected.Contact between my friends and family was significantly reduced to the odd text message here and there. I couldn’t enjoy my usual web browsing on BBC iPlayer, social media sites, keeping up to date with the news, or even wanting to know the opening hours of shops in the new area I was in.I didn’t, however, spend a full four months without connecting to a Wi-Fi network. It was only a five minute walk to the reception where I could connect for free and spend as much time online as I wanted to at my own leisure. It made me think , though , how unnecessary it can be , how unnecessarily we rely on it—how we perhaps rely on it too much. As a person, I was more sociable. I spent more time with my housemates instead of hiding behind a computer screen. I did other things that I wouldn’t necessarily have done if I could have browsed the web at my leisure. I read more, I cooked meals for my friends, and I even tidied up more often. Dare I say it; I learned how to live without Wi-Fi. Dare I say it; I found it was easier than I had imagined.12. What was the writer’s first feeling when finding her house had no Wi-Fi?A. Unexpected.B. Angry.C. Shocked.D. Depressed.13. How did the writer keep in touch with her friends and family without Wi-Fi?A. By writing regularly.B. By text message.C. By video calls.D. By telegram.14. What was the writer’s life like without Wi-Fi?A. Dull.B. Lonely.C. Active.D. Relaxing.15. What can be a suitable title for the text?A. A life without Wi-FiB. Different views on the InternetC. The disadvantages of Wi-FiD. How to use the Internet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。

2020-2021学年南京市第十二中学高三英语上学期期中考试试题及答案

2020-2021学年南京市第十二中学高三英语上学期期中考试试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AMy mother and her best friend Martha were in their mid-80s when they saw each other for the last time.They had been friends since they were 18, both of them students atWesleyanCollegeinMacon,Georgia. My mother was the dreamy one, who loved to read and dream herself as an actress. Martha, however, was more practical. I’m not sure what they had in common except that they trusted each other, helped each other, and stayed in touch even when life separated them.Martha spent most of her adulthood inAtlanta, where she raised three kids. My mother, meanwhile, raised eight children, and moved many times during her financially and emotionally troubled marriage, which included several months living with her family inseedymotels.I sensed my mother hid her troubles from most people, but not from Martha, and I knew from my mother that Martha carried her own sorrows. Their willingness to share sorrow without judgment was part of what bond them.The best friendships can also withstand (抵挡) periods without communication. They didn’t communicate a lot — this was before the ease of emails and texts and yet I knew they were always in each other’s minds.One day in 2008, 1 drove my mother to Martha’s house for their final visit. The moment my mother hobbled (蹒跚) into Martha’s house, they threw their arms around each other and went to sit out in the garden, laughing until they were dizzy. I snapped a photo, and spotted something joyous, young and free on my mom, which existed only in the presence of her best friend.Two years later, my mother died. Of all the people I had to tell, Martha was the hardest because I felt it erased her past. After that, we lost touch. But I still think of her and how that friendship strengthened my mother.1. What does the underlined word “seedy” in Paragraph 3 probably mean?A. largeB. dirtyC. urbanD. bright2. The author’s mother and Martha had a lasting friendship partly because they________.A. were willing to shareB. were constantly in touchC. had much in commonD. had a likeness in personality3. What is the author’s purpose in writing the text?A. To tell the importance of friendship.B. To express his gratitude to his mother.C. To share his standard of choosing a friend.D. To praise the friendship between Martha and his mother.BWhen I was 9, we packed up our home in Los Angeles and arrived atHeathrow, London on a gray January morning. Everyone in the family settled quickly into the city except me. Without my beloved beaches and endless blue—sky days, I felt at a loss and out of place. Until I made a discovery.Southbank, at an eastern bend in the Thames, is the center of British skateboarding, where the continuous crashing of skateboards left your head ringing .I loved it. I soon made friends with the local skaters. We spoke our own language. And my favorite: Safe. Safe meant cool. It meant hello. It meant don't worry about it. Once, when trying a certain trick on the beam（横杆）, I fell onto the stones, damaging a nerve in my hand, and Toby came over, helping me up: Safe, man. Safe. A few minutes later, when I landed the trick, my friends beat their boards loud, shouting: “Safe! Safe! Safe!” And that's what mattered—landing tricks, being a good skater.When I was 15, my family moved to Washington. I tried skateboarding there, but the locals were far less welcoming. Within a couple of years, I'd given it up.When I returned to London in 2004, I found myself wandering down to Southbank, spending hours there. I've traveled back several times since, most recently this past spring. The day was cold but clear: tourists and Londoners stopped to watch theskaters. Weaving（穿梭）among the kids who rushed by on their boards, I found my way to the beam. Then a rail—thin teenager, in a baggy white T—shirt, skidded（滑）up to the beam. He sat next to me. He seemed not to notice the man next to him. But soon I caughta few of his glances. “I was a local here 20 years ago,” I told him. Then, slowly, he began to nod his head. “Safe, man. Safe.”“Yeah,” I said. “Safe.”4. What can we learn about the author soon after he moved to London?A. He felt disappointed.B. He gave up his hobby.C. He liked the weather there.D. He had disagreements with his family.5. What do the underlined words “Safe! Safe! Safe!” probably mean?A. Be careful!B. Well done!C. No way!D. Don't worry!6. Why did the author like to spend time in Southbank when he returned to London?A. To join the skateboarding.B. To make new friends.C. To learn more tricks.D. To relive his childhood days7. What message does the author seem to convey in the text?A. Children should learn a second language.B. Sport is necessary for children's health.C. Children need a sense of belongingD. Seeing the world is a must for children.CIn many countries of the world, people can confidently tell youthe meaning of their town or city, but most people who live inManchester,OxfordorBirminghamwould not be able to explain what the name of their city means. The name of every British town and city, however, has a long history.Two thousand years ago, most people living inBritainwere Celts. Even the word “Britain" is Celtic (凯尔特语).Then the Romans arrived and built camps which became cities called “castra". This is why there are so many place names inEnglandwhich end in "-chester" or “-caster"Manchester, for example.The Romans never reachedWalesorScotland, and many placenames there are Celtic. For example,Welsh place names that begin with “Llan" come from the Celtic word for "church".After the Romans leftBritain, it was attacked by the Anglo-Saxons who were from the area of Europe that is nowGermanyandHolland. The names of their villages often ended in “-ham" or “-ton". Some got their names from the leader of the village.SoBirminghamfor example, means "Beormund's village”The Anglo-Saxons were farmers and the landscape was very important to them, so we have villages called Upton (village on a hill)——a good place to build a village and Moreton (“village by a lake”)where floods could make life hard. Place names that end in “-ford" (a place where you could cross a river) also describe the location of Anglo-Saxon villages.Finally, in 1066EnglandbecameNorman—theNormansgave us the place name "grange", which means farm.And how aboutLondon? Experts cannot agree. The Romans called the city Londinium, but they were not the first inhabitants (居民). People once believed that theUnited Kingdom’s capital city got its name from the castle of a King called Lud but this is very unlikely. Our best guess today is that the name comes from a Celtic word meaning a fast-flowing river. Like a number of British place names, its history is lost in time.8. The origin of British place names is unfamiliar to many local people because ofA. the death of local languagesB. the long lost history of the namesC. their lack of interest in itD. the frequent changes to the names9. According to the article,Stratfordis most likely a town .A. on a hillB. near a castleC. beside a riverD. with a church10. Which of the following shows the correct order of the arrival of inhabitants inBritain?A. The Celts—The Romans—TheNormans—The Anglo SaxonsB. The Celts—The Romans—The Anglo Saxons—TheNormansC. The Romans—The Celts—The Anglo Saxons—TheNormansD. The Romans―The Anglo Saxons—The Celts—TheNormans11. What doesLondonmean in Celtic?A. RiverB. LondiniumC. LudD. CastleDWe asked four people who watched an online talk on technology and communication by Sherry Turkle for their opinions.Fred:The talk certainly gave me plenty of food for thought about how technology is changing our behaviour. People are constantly multitasking, whether it be emailing during meetings or texting in the checkout queue. It’s as if we can’t bear to miss out on what our online friends are up to, so we juggle the real and online world. My greatest concern is that we don’t give our brains a chance to switch off. It’sthese precious momentswhen we actually process information that helps us make important decisions.Jeremy:It was a fascinating talk and the speaker really hit the nail on the head with a couple of things. Take parental influence, for instance. How can we expect teenagers not to text while doing their homework when they witness their parents posting on social media while cooking the evening meal or waiting at a red light?Kath:So much of what the speaker said rang true. I honestly believe there’s a danger that the more connected we are, the more isolated we feel. I don’t think this is such an issue for my generation who’ve lived withouttechnology for so long. We know how to be alone. But the under 20s are another kettle of fish. They’re so busy communicating that they never experience the feeling of solitude and run the risk of not learning how to enjoy their own company.Carl:I’m not sure to what extent I agree that people are more alone, but the way we communicate has certainly evolved. The speaker makes a good point about how we’re getting used to talking with machines like Siri or robots, which are totally lack of experience of human life. But despite such limitations, we seem to be expecting more from technology and less from each other.12. What does the underlined phrase “these precious moments” in paragraph 2 refer to?A. When our brains are free.B. When we emailing during meeting.C. When we texting in the checkout queue.D. When we juggle the real and online world.13. What suggestion may Jeremy give to the parents?A. Accompany their children when they are doing homework.B. Prevent their children using phone while doing homework.C. Set a good example for their children on using phone properly.D. Stop posting on social media in face of their children.14. What does Kath worry about the under 20s generation?A. They communicate more with others.B. They use more technology.C. It’s difficult for them to find companies.D. They don’t know how to be alone.15. What is Carl’s attitude towards the use of technology in communication?A. Favorable.B. Intolerant.C. Doubtful.D. Indifferent.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。

Here are some of the museum’s most moving moments.The Olympic ParkThe journey through the Olympic Museum begins in the Olympic Park, an 8,000-square-meter outdoor area in front of the museum overlooking Lake Geneva and theAlps. The park contains artwork and sculptures that show respect to the world of sport.The first Olympic symbolThe “Olympic Rings” flag was designed by Coubertin in 1913. The rings represent the five continents that participate in the Olympics: Africa, Asia,America,AustraliaandEurope. The six color1 s include at least one color1 that is represented on the flag of every country.The stadiumsThe stadiums that host the Olympic Games are as much of a celebration of design as the games are a celebration of sportsmanship. Guests can explore plans and models of Olympic stadiums’ past and present, including one of the games’ most attractive stadiums, the Bird’s Nest from Beijing 2008 Olympics.The Olympic medalsHave you ever wondered what an Olympic medal looks like? The Olympic Museum has a room that houses every bronze, silver, and gold medal from every Olympic Games dating back to the first modern Olympics of 1896. Each medal design is a unique representation of the year and location in which the games were held.1.Which moment do you see first when exploring the Olympic Museum?A.The Olympic Park.B.The first Olympic symbol.C.The stadiums.D.The Olympic medals.2.What do you know from The first Olympic symbol?A.The first modern Olympics took place inGreece.B.There are six color1 s on the flag of every country.C.Australia used to be the largest continent on earth.D.The “Olympic Rings” flag was created in 1913.3.What can you do in the section of The stadiums?A.Admire the view ofLake Geneva.B.Meet some famous designers.C.Enjoy the model of the Bird’s Nest.D.Talk with guests of honour.BScott and Daniel Harry are enjoying everyday tasks like shopping and washing for the first time following their move to an accommodation (住宿) support house in Kurwongbah, north of Brisbane last year.Disability Services Queensland’s Strengthening Non-Government Organisations project provided an accommodation support model that would enable residents (居住者) like Daniel and Scott to live more independently.The house is just one of many accommodation support services funded (资助)through the project. The five-bedroom house provides 24-hour care for up to four individuals with complex needs, including medical support. Care and staffing levels are varied and flexible, depending on each resident’s requirements.Scott and Daniel, who have a severe form of Duchenne Muscular Dystrophy, require 24-hour support in all activities of daily living. Before they moved to the house, they lived with their family. Scott says living at home was difficult as it placed a physical and emotional strain(负担) on their parents who had to wake them several times each night to reposition them or place them on breathing machines.“We were heavyhearted,” says Scott, who is planning to write a book about his life experiences. “But our parents now have a lot moretime for themselves. We now manage ourselves on a day-to-day basis.”Daniel is an enthusiastic gardener, taking care of his own vegetable garden. The men share the house with one other young man, and they go to rugby league games, meeting up with friends.Leeding Care Australia provides the care service at Kurwongbah. Manager Lee Garniss says setting up the facilities (设施) has not been without its challenges.“It is an unconventional model of care,” Lee says. “The home is Scott and Daniel’s home, however it is also a workplace for their support staff. Balancing these two requirements has been a challenge for all.”“We have experienced a bit of a learning phase over the last twelve months. However, by working as a team we try our best to meet the needs of both residents and staff and I think we have achieved the right balance.”4.

Satisfying both staff and residents’ needs.CA crew（全体成员）of six teenage girls completed a nine-day sailing trip in the US recently, after having seasickness and strong winds.For the past three years, the Sea Cadet teenagers whoset sail were all male. Roger Noakes, who captained（担任队长）the boat, said this was the first time he’d taken out an all-female crew.The girls asked for an all-girls trip in August this year. The crew set sail along with three adults, Noakes and two Sea Cadet representatives. The original plan was for the girls to sail 24 hours a day in rotating shifts（轮流换班）along the coast and then return. Things turned out differently, however. “The first night was difficult because the wind was really hard. The waves were going up and down,” said Abby Fairchild,16. “Everybody got seasick.” Noakes gave the girls the choice of just sailing in the bay and not going into open water. “But they decided they were going.”The teenagers then sailed a long way overnight and slept in shifts. “We’ve learned everything from controlling the boat to putting up the sails while we have rough seas,” said 15-year-old Olivia Wilcox.The teenagers stopped on land in Massachusetts. They didn’t make it to their original destination（目的地）in Maine, where they were supposed to have a celebratory dinner, due to the weather and winds. They said they weren’t disappointed, however, as they’d learned a lot. “They learned about boating, and above all, they built confidence and character,” said Noakes.8. What was special about the Sea Cadet trip this year?A. It was the longest sailing trip ever.B. It was the first all-female-crew sailing trip.C. It was the most dangerous sailing trip ever.D. It was the first sailing trip for teenagers.9. What happened on the crew’s first day of the trip?A. They all felt sick on the boat.B. Some of them were hurt.C. Their boat was out of control.D. They went into open water by mistake.10. Which of the following best describes these young sailors?A. Strong-minded and having a strong sense of teamwork.B. Hard-working and having great leadership skills.C. Understanding and creative.D. Adventurous and skillful.11. According to Noakes, what was the sailors’ greatest benefit from the trip?A. They knew the sea better.B. They made many friends.C. They got excellent sailing skills.D. They developed good personalities.DImagine that youare a superhero. Your superpowers are activated by a special suit. The suit communicates with your brain. It allows you to do amazing things with only a thought. By concentrating on strength, for example, you can kick a soccer ball across a field. By focusing on swift actions, you can jump to the top of a tree.Such a connection between mind and machine may sound like a fantasy. To scientists, though, it is a very real goal. They are creating machines that let disabled monkeys walk. These machines may soon help disabled humans do the same. Unlike other bionic devices, these robotic “super suits” do not communicate with muscles and nerves. Instead, they have a direct line to the brain.In 2005, doctors drilled a hole in the skull of Hutchinson, who had lost her right arm in an accident. Then they inserted a sensor onto her motor cortex (大脑皮层运动区). Wires connected the sensor to a receiver on her head.After she recovered, researchers pluggedHutchinson’s receiver into a cable that relayed signals from her brain to computers. Then they connected a robotic arm to the computers. The computerscould interpretHutchinson’s brain signals to move the arm.Soon,Hutchinson, the computer, and the robotic arm became a team.Hutchinsonwas even able to lift her hand and drink from a cup. “She smiled when she put down that drink—that’s everything.” says Donoghue, a brain scientist.Today other scientists are building on that success. One of those scientists is Dr. Miguel Nicolelis, who designed a whole-body bionic equipment. In 2014, a disabled former athlete kicked the first ball of the World Cup Games wearing one of Miguel’s full-body exoskeletons.The exoskeleton was connected to brain signal sensors in the man’s cap. By thinking about kicking, he sent signals to a computer on his back. The computer then translated the signal into an exoskeleton-aided kick. Such designs may become common as scientists keep merging mind and machine.12.Which can best describe the tone of paragraph 1?A. Narrative and serious.B. Persuasive and critical.C. Informative and objective.D. Descriptive and imaginative.13. What is paragraph 3 mainly about?A. Reason of the experiment.B. Results of the experiment.C. Process of the experiment.D. Significance of the experiment.14. Why is Dr. Miguel’s exoskeleton special?A. It can be used on animals.B. It can move the whole body.C. It was supported by computers.D. It was connected directly to the brain.15. What can be inferred from the last paragraph?A. Robotic suits may be widely used to help disabled people.B. Exoskeleton is more common thanHutchinson’s bionic arm.C.Scientific experiments are commonly carried out in football fields.D. Disabled athletes can now play football again with the help of computer.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。

They are just pictures,but the feelings are real. This skill, to understand the thinking and feeling of others, is what researchers call "theory of mind".For example, think about the faces of people and animals in stories. The Big Bad Wolf's scary teeth. The 'o' shape of a surprised character's mouth. Or big, wide eyes like the girl inOwl Moon.By noticing the faces,readers can start to figure out what it feels like to be that character.And that helps to figure out how people feel and think in real life.But most young readers don't go into deep,scary woods.And some may not go to the beach or play basketball.In the bookYo!Yes?two kids meet and play ball. The kids start the story on opposite pages.But as the story goes on,they get closer until they are together.Some young readers might not play basketball, but they can read the clues on the page to figure out how the kids are feeling.And some readers might not like the game,but they can feel excited for the characters because of how the characters look and move.4. What can we learn from the second paragraph?A.Owl Moontalks about the exploration of the Moon.B. The feeling of"amazement"is a sense of agreement.C. Readers are blessed with the ability to interpret others.D. Readers with similar experience understand the story better.5. Which of the following might help readers develop"theory of mind"?A. True feelings.B. Smiling faces.C. Picture books.D. Reading skills.6. Young readers can go deeper into a story by________.A. tracking the plotB. developing new skillsC. sharing similar hobbiesD. analyzing the background7. What is the text mainly about?A. How thinking influences reading.B. How readers improve reading skills.C. How emotions help enhance reading.D. How kids figure out the clues of stories.CSometimes people make history. George Washington became the first president of theUnited Statesand made history. Sometimes wars make history. The two World Wars are examples. Sometimes nature even becomes part of history. Shaking earthquakes are recorded in history books.Sixteen years ago, nature caused just such a history-making event. In September 2005, Hurricane Katrina came ashore inNew Orleans,Louisiana. The deadly storm floodedNew Orleans. Before Katrina, no other big American city had ever flooded in the history of the country. This natural disaster caused great harm and death.New Orleansis located below sea level. This location places it at great risk. Levees were built to protectNew Orleansfrom the ocean. (A levee is like a wall between the city and the ocean.) When Hurricane Katrina came ashore, water moved over the levees into the city. Flooding made it necessary for everyone to leave the city. Before Katrina, Creole food (a special kind of cooking only inLouisiana) filled the air with delicious smells. The sound of jazz music traveled through the streets. Now the city has to return to its former glory.Before Katrina, ernment had never made everyone leave a city. People inNew Orleanshad to find shelter quickly. Some had to stay at theSuperdomeSportsCenter. Some rode on buses to other towns. Thousands drove their cars to get away from the storm. The roads and shelters filled up fast.The lesson learned from Katrina was that cities must be better prepared for big storms and other terrible disasters caused by nature. Being prepared might have kept more people safe. Hurricane Katrina is one of the history-making events that will be remembered forever. Today, history is still being made that will shape the future.8. What does the author tell us aboutNew Orleans?A. It was built above sea level.B. It had few jazz musicians after Katrina.C. It was the firstU.S.city that had been flooded.D. It created a wholly new way to cook after Katrina.9. What can we say about the levees?A. They were almost useless for fighting Katrina.B.

What might the author advise city governments to do?A. Put up more shelters in the city.B. Build more levees around the city.C. Teach people how to avoid floods.D. Try to get ready for natural disasters.11. What is the best title for the text?A. Storms are dangerousB. Katrina makes historyC. Floods shapeLouisianaD. History must be rememberedDThe United Nations Educational, Scientific and Cultural Organization (UNESCO) included on December 17, 2020 China's Tai Chi on the Representative List of the Intangible（无形的）Cultural Heritage of Humanity. The decision was announced during the online meeting of the UNESCO Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage held from December 14 to19 inKingston, capital ofJamaica.“Born in the mid-17th century in a small village named Chenjiagou located in Central China's Henan province, Tai Chi is not only a kind of traditional Wushu integrated with slow movements and deep breathing, but is also deeply rooted in many areas of Chinese culture, such as medicine and philosophy,”Zhu Xianghua says, who is the son of the famous Tai Chi master Zhu Tiancai.Although it has spread to more than 150 countries and regions, attracting more than 100 million people to practice, the idea that Tai Chi is for the elderly has stopped many young people practicing the ancient Wushu. They think of it as a slow exercise, which is specially made and better suited for their grandparents. Instead, many young people are turning to the Indian practice of yoga（瑜伽）to relieve stress, which was placed on the UNESCO's List in 2019.In order to promote Tai Chi, joint efforts have been made from individuals and the Chinese government in the last decades. Xi'an Jiaotong University requires students to learn Tai Chi. Wang Yunbing, a professor in theuniversity's sports center, stressed that Tai Chi is not only good physical exercise-researchers from the American College of Rheumatology find that it can help manage several diseases but is also conned ted to ancient Chinese eivilization. Since 2014, the World Tai Chi Championships have been held every two years by the International Wushu Federation. It provides a platform for communication and learning between the Tai Chi masters and Tai Chi lovers around the globe. In January 2020, Tai Chi became an official event in the 2026 Dakar Youth Olympic Games.12. What does Zhu Xianghua say about Tai Chi in paragraph 2?A. It originated from fast Kung Fu action.B. It was born around the 1750s in a village.C. It is related to other cultural fields ofChina.D. It integrates Chinese medicine and western philosophy.13. Why do some young people choose to practice yoga instead of Tai Chi?A. They think it easier to practice yoga to keep fit.B. The elderly stop young people practicing Tai Chi.C. They consider Tai Chi is custom-built for old people.D. Yoga was included in the world culture earlier than Tai Chi.14. What is the main purpose of the last paragraph?A. To promote contemporary Chinese civilization.B. To show many efforts made to popularize Tai Chi.C. To stress the importance of Chinese Tai Chi masters.D. To advise people to practise Tai Chi to cure diseases.15. Which of the following is the best title for the passage?A. Tai Chi Steps on the UNESCO's List.B. Tai Chi isCompeting against Yoga.C. Tai Chi Has Regained populate Globally.D. Opinions Greatly Differ on Tai Chi and Yoga.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。

（16分）心灵之痛查一路⑴车行到小区门口，前面一个刚放学的小女孩，不知在张望什么。

出于安全考虑，我轻摁了一下喇叭。

接下来发生的事，让我感到十分意外。

⑵小女孩有瞬间的惊悸，然后回过头，恶狠狠地瞪着这边。

她的眼神吓着了一个手握方向盘的成年人，我摇下车窗，想在车子经过时安抚一下她。

不料，在我开车经过的一刹那，我清晰地听到她骂了一句很脏的话，脏得让我当时无法逃避，此刻无法转述。

我很震惊，一个不过上三四年级的小女孩，怎么能说出这么脏的话呢？⑶我以前没遇到过这样的事，如果用“震惊”来形容可能危言耸听了点儿，但这么脏的一句话，至少让我几个星期都不能释怀。

具体原因不可知晓，可以肯定的是，这孩子的心里有些痛，由痛而引发了一种恨。

⑷一个月后，我又见到了这个女孩，还是在小区的门口。

这次她坐在她妈妈的电瓶车的后面，她的声音很大，反复问：“妈妈，我们家为什么不买汽车啊？别的同学家都有车。

”烈日下，她的母亲只顾锁着眉头骑车，无暇回答她的提问。

⑸无意中，这个小女孩已经告诉了我答案。

⑹前段时间，因一场暴雨，一个亲戚让我帮他接小孩。

放学时节，某小学门前的广场上，车声鼎沸，喇叭声震耳欲聋。

一眼望去，雨雾之中处处是小车，挤满了整个广场，都是来接孩子的。

也有家长骑着摩托车、电瓶车、自行车，他们让孩子穿着雨披坐在身后，穿行于停在广场的汽车中间。

⑺坐在汽车里的孩子们，则透过车窗玻璃，安逸地望着窗外，望着被雨水打湿的同学们。

⑻国外的富翁，不会把私人游艇停靠在公共码头；而中国的富裕阶层，甚至仅仅是普通的有车一族，都希望自己的车轮在别人艳羡的目光中滚动。

⑼由此，我想起了那个小女孩的心灵之痛。

⑽这些年，我注意到社会上一些人的心头有某种不便说出的痛。

有些痛，源于社会的一种病；有些痛，源于社会成员彼此间的疏离与隔膜。

就说关于车这样的小事，如果有车的家长们尽可能把车停到离校门口远一点的地方，如果开车的人尽可能不冒失地摁喇叭，“有车没车”的意念可能就不至于在孩子的心灵上划出一道伤痕。

⑾有些痛，从根源上讲，不是我们造成的，但与我们有关。

因为无意间的冒犯与入侵，往往伤害了他人的情感。
