And it would help if you wore a hat. The sun is too bright.3. W: Well, Mr. Anderson, you are at great risk since you smoke and drink too much.M: Am I in a serious condition, doctor?W: Yes, absolutely. It might be a good idea if you give up smoking and drinking as well.M: Oh, dear... I’m afraid that’s out of t he question.4.

All the housewives who went to the new supermarket had one great ambition: to be the lucky customer who did not have to pay for her shopping. For this was what the notice just inside said. It said: “Remember, once a week, one of our customers gets free goods. This May Be Your Lucky Day!”For several weeks Mrs. Edwards hoped, like many of her friends, to be the lucky customer. Unlike her friends, she never gave up hope. The cupboards in her kitchen were full of things which she did not need. It's no use her husband trying to stop her. She dreamed of the day when the manager of the supermarket would come to her and said: "Madam, this is your lucky day. Everything in your basket is free."One Friday morning, after she had finished her shopping and had taken it to her car, she found that she had forgotten to buy any tea. She ran back to the supermarket, got the tea and went to pay for it. As she did so, she saw the manager come up to her. "Madam," he said, holding out his hand, "I want to congratulate you! You are our lucky customer and everything you have in your basket is free."。

2016年高考新课标卷寒假考练--英语试题(一)配答案

2016年高考新课标卷寒假考练—英语试题（一）配答案AWhen Josephine Cooper was growing up，she learned the importance of charity from her parents．Although they made a modest living for their family of 10，they insisted on sharing with those less fortunate．Half a century later，Mrs. Cooper became a beloved volunteer at the San Diego Food Bank，where she devoted herself to helping others．She organized and ran a distribution center from a church，helping it become the organization’s largest emergency food distribution center in San Diego．She was one of 25 outstanding senior volunteers in the nation selected and invited to Washington D．C．to receive the award．―She was the main person who helped us make that program grow,‖ said Mike Doody，former director of the Food Bank．―She had a way of g etting people to work together and to work hard．She was determined and stubborn，but in a good way．She had a good heart．‖ People knew her as ―Grandma‖ because of her selflessness and her devotion to helping hungry children and families．―She reminded people of their Grandma.‖ Doody said．As a widow with a young child in 1979，Mrs．Cooper was helped through a difficult financial time when the Food Bank provided her with groceries．―She dedicated her life to giving back,‖ said her daughter，Monica Cooper．It wasn’t unusual for a local church to call Mrs Cooper to ask her to aid a needy family．―She would give people food out of her cupboard．Sometimes we would cook a meal for a family living out of their car,‖ Cooper said．Although Mrs Cooper was honored to receive the national award for her volunteer work，she said being able to help others was her reward．She died of liver disease and kidney failure，aged 93．1．The underlined word ―charity‖ in Paragraph 1 refers to ．A．offering help B．donating money C．providing services D. showing sympathy2．Which of the following is true of Mrs. Cooper?A．She died at an early age B．She refused the national award．C．She was kind and devoted．D．She was not easy to get along with．3．Mrs Cooper’s story suggests that ．A．everyone needs a Grandma nearby B．children are what their parents areC．a sound mind is in a sound body D．a mother’s love never changesBThose who have suffered from insomnia know the sinking feeling of watching the clock tick．Now a new study in the Archives of Internal Medicine suggests that lying in bed awake may actually contribute to the problem of sleeplessness．The study of 79 adults（average age 72）with insomnia aimed to determine whether brief behavioral interventions for insomnia would help．Traditional behavioral therapy （疗法）requires at least half a dozen hour-long sessions with a therapist — a costly commitment many patients either can't make or don't have access to．Other options include sleep-aiding medications or supplements．In the current study，the 39 participants in the behavioral therapy group received a 45-to-60-minute instructing session，plus a 30-minute follow-up session and two 20-minute phone calls．Doctors offered the following behavioral interventions for improving sleep: reduce time in bed; get up at the same time every day，regardless of sleep duration; don't go to bed unless sleepy; and don't stay in bed unless asleep．The other 40 participants in the study were given printed educational materials about insomnia，which included the same instructions given to the intervention group，but without the individualized sessions with a therapist．Two weeks later，the latter group also got a 10-minute follow-up phone call．At the end of four weeks，the behavioral treatment group was significantly more likely to show improvements in sleep than the printed-materials group．By that time，55% of those who received behavioral treatment no longer met the criteria for insomnia，compared with 13% of the group that got educational brochures．The good news comes at the same time as a report on the health effects of insomnia from the U.K.’s Mental Health Foundation．The report，Sleep Matters，suggests a link between insomnia and poor relationships，low energy levels and an inability to concentrate．Poor sleep has already been linked to depression，immune deficiency and heart disease．4．What is the meaning of the underlined word ― insomnia‖?A．sleeplessness B．depressionC．heart disease D．immune deficiency5．What is the disadvantage of traditional behavioral therapy?A．It can’t help．B．It costs a lot of money．C．It requires sessions with a therapist．D．It includes sleep-aiding medications．6．How to improve sleep according to the doctor?A．Lying in bed awake．B．Get up early every day．C．Don’t go t o bed late at night．D．Don’t stay in bed if you are not asleep．7．We can learn from the text that insomnia may cause the following results except_____．A．depression B．concentration C．immune deficiency D．heart diseaseCDhaka's pedal-powered tricycles (脚踏三轮车) may not appear high-tech but they keep the commuters moving and do no damage to the environment.Travel, they say, broadens your mind. I am not sure if it really does but it is certainly an experience in itself. Just like the food, the public transport is also an experience. Dhaka streets are full of carbon emitting buses and trucks and noisy cars.Traffic jams are a part of daily life in Dhaka. Residents say vehicle-related pollution has been more and more serious over the last few years. Perhaps to ease the situation, some of the many non-profit non-government organizations –and the civil society ought to launch a ―Save the Capital campaign‖.It is true that in Dhaka at any hour of the day and in many areas, there are always crowds of people going somewhere –or just waiting for something to happen. One thing is sure: You will never feel lonely!One form of transport which is extremely popular, widely available, cheap, private and eco-friendly is a three-wheeled invention called rickshaw(人力车). The most interesting feature of these slow-moving pedal-powered transport is the bright and colourful ―moving art‖ which decorates their side and back. The drawings range from romance to the wildest flights of fantasy. The scenes are common: airplanes, helicopters, and gun-battles, masked men in sports cars, rosy cheeked well-endowed women, palatial mansions, rivers and green landscape.When you hire a rickshaw, make yourself ―comfortable‖ and tell the driver your destination, you have then become a part of the moving art exhibition. The rickshaws are decorated in vivid colors, from front to back.We cannot deny that the rickshaw art however modest it may be reaches millions everyday –something only dreamt of by the likes of Picasso, Van Gogh, Turner or Monet.While at the local level the rickshaws provide a readily available cheap means of transport and a way out of the crowded Dhaka streets, on a broader and international level the rickshaws are contributing to help bring down the city’s pollution levels and ease global warming.8. The first paragraph serves as a(n) ________.A. explanationB. introductionC. commentD. background9. According to the passage, the writer agrees that ________.A. we can broaden our mind when travelingB. traffic jams is the most serious problem in DhakaC. we can experience public transport when travelingD. Dhaka is the most famous travel destination10. It is true that in Dhaka ________.A. there are still not enough rickshawsB. it is a little expensive to hire a rickshawC. rickshaws are very popular and eco-friendlyD. rickshaws are decorated with the drawings of famous artists11. It can be inferred from the passage that ________.A. the writer thinks highly of rickshawsB. rickshaws will be popular all over the world soonC. the drawings on the rickshaws covers limited topics.D. the government has launched a ―Save the Capital campaign‖12. What is the main purpose of the text?A. To introduce Dhaka to tourists.B. To report recent news in Dhaka .C. To teach tourists how to use rickshaw.D. To provide some traffic information in Dhaka.DThe Diet Zone: A Dangerous PlaceDiet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet .... We are surrounded by the word ―diet‖ everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.Diet products significantly weaken us psychologically. On one level, we are not allowing our brains to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale （秤）instead. All we have to do is to swallow or recognize the word ―diet‖ in food labels.On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients (营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous.Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological and physical harm that comes from using them.13. From Paragraph 1, we learn that ______.A. diet products fail to bring out people’s potentialB. people have difficulty in choosing diet productsC. diet products are misleading peopleD. people are fed up with diet products14. In Paragraph 3, ―gain comes without pain‖ probably means ______.A. losing weight is effortlessB. it costs a lot to lose weightC. diet products bring no painD. diet products are free from calories15. Diet products indirectly harm people physically because such products ______.A. are over-consumedB. lack basic nutrientsC. are short of chemicalsD. provide too much energy七选五：每题二分You think you know your dog．16 She probably recognizes you when she sees you．But can a dog tell by simply looking at you whether you have a happy or an angry expression on your face? Researchers in Austria have taught pet dogs to know the difference.17 When dog owners shout or speak in a strong，sharp voice，dogs often act guilty and quietly move away from the area．Recently，researchers found that dogs can look at our faces，and tell the difference between a smile and a frown．The animals were able to recognize a look of approval from one of disapproval．Researchers at the University of Veterinary Medicine performed a series of experiments．18 They showed the dogs two pictures of either the upper or lower half of a person’s face．On one picture，the person looked happy．The other appeared angry．The dogs were then shown images of the eyes or mouths of people they had never seen before．19 Once the dogs learned to recognize which image was happy or angry，they could easily identify the same expressions in pictures of any face．Future studies will try to show whether dogs can learn the meaning of facial expressions．20 The researchers’findings were published in the journal Current Biology．They provide the first solid evidence that humans are not the only species that can read the body language of another species．A．Dogs are very aware of sound．B．Dogs have feelings just as you do．C．But how well does your dog know you?D．They were also shown the left half of the faces used in training．E．Some dogs are very unhappy when they are left alone for a long time．F．They taught dogs to recognize facial expressions．G．For example，whether a frown shows that someone is angry．完形填空：每题1.5 分When I was thirteen, one day my mom told my family that she had to tell us something．So my dad, my brother and I all sat down on the sofa to begin the discussion．You could feel the 21 atmosphere of the room．It was 22 that something was wrong．Then my mom told us that she had been diagnosed with a very serious disease．That was when we all had a moment of 23 and cried．After that my mom started the 24 and had to travel to the hospital every day．After a week, she began to lose her 25 and so she shaved it all off．My mom would always wear bright-colored scarf’s and after a while 26 to buy a wig ．Along with losing her hair she lost all her nails．27 , I had never seen a desperate look in my mom's eye．I remember one day I went with my mom to the hospital．When we were 28 for her to receive the treatment, we kept telling jokes．We both burst out 29 from time to time．Everyone in the waiting room was so 30 , while we were in the middle of the room, chatting 31 .

AMany animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when giventhe choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such asFranceandBritain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.1. We can infer from the text that humans and animals.A. depend on one sense in choosing foodB. are not satisfied with their foodC. choose food in similar waysD. eat entirely different food2. Which of the following eats only one type of food?A. The white butterfly.B. The small bird.C. The bear.D. The fox.3. Certain animals change their choice of food when _________.A. the season changesB. the food color changesC. they move to different placesD. they are attracted by different smells4. We can learn from the last paragraph that.A. food is chosenfor a good reasonB. French and British food is goodC. some people have few choices of foodD. some people care little about healthy dietBCAREER OPPORTUNITES(1)Full-time Secretary Position Available: Applicants should have at least 2 year’s experience and be able to type 60 words a minute.No computer skills required.Apply in person at United Business Ltd, 17 Browning Street, Leeds.(2)Part-time Job: We require three part-time shop assistants to work during the evening.No experience required, applicants should be between 18 and 26 yearsold.Call 0115665643 for more information.(3)Computer Trained Secretaries: Do you have experience working with computers?

While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries (食品杂货), saving us from having to walk long distances from where we live.I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that，several people in our area offered to help. One wonderful stranger even bought a bike, and then called my husband to pick it up. Once again myhusband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity (人性) as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.8. Why was the bike so important to the couple?A. The mans job was bike racing.B. It was their only possession.C. It was a nice Kona 18 speed.D. They used it for work and daily life9. We can infer from the text that__________.A. the couple worked 60 hours a weekB. people were busy before ChristmasC. the stranger brought over the bikeD. life was hard for the young family10. How did people get to know the couples problem?A. From radio broadcasts.B. From a newspaper.C. From TV news.D. From a stranger.11. What do the couple learn from their experience?A. Strangers are usually of little help.B. One should take care of theirbike.C. News reports make people famous.D. An act of kindness can mean a lot.The Peales were a famous family of American artists.Charles Willson Peale is best remembered for his portraits of leading figures of the American Revolution.He painted portraits(肖像) of Franklin and Jefferson and over a dozen of George Washington.His life-size portrait of his sons Raphaelle and Titian was so realistic that George Washington reportedly once tipped his hat to the figures in the picture.Charles Willson Peale gave up painting in his middle age and devoted his life to the Peale museum, which he founded in Philadelphia.The worlds first popular museum of art and natural science mainly covered paintings by Peale and his family as well as displays of animals in their natural settings.Pealefound the animals himself and found a method to make the exhibits more lifelike.The museums most popular display was the skeleton(骷髅)of a huge, extinct elephant, which Pealeunearthedon a New York farm in 1801.Three of Peales seventeen children were also famous artists.Raphaelle Peale often painted still lives of flowers, fruit, and cheese.His brother Rembrandt studied under his father and painted portraits of many noted people, including one of GeorgeWashington.Another brother, Rubens Peale, painted mostly landscapes and portraits.James Peale, the brother of Charles Willson Peale, specialized in miniatures(小画像).His daughter Sarah Miriam Peale was probably the first professional female portrait painter in America.12.The author mentions in Paragraph 1 that Washington tipped his hat to the figures in the painting to show that ________.A.Charles Willson Peales painting was very lifelikeB.Washingtonrespected Charles Willson Peales workC.Washingtonwas friendly with Raphaelle and Titian PealeD.the painting of the two brothers was very large13.The underlined word “unearthed” is closest in meaning to“ ______”.A.showedB.inventedC.dug upD.looked over14.Which of the following is NOT the child of Charles Willson Peale?A.Titian Peale.B.Rubens Peale.C.Raphaelle Peale.D.Sarah Miriam Peale.15.The authors attitude toward the Peales is in general _______.A.puzzledB.admiringC.excitedD.disappointed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。

(人教版)九年级物理2016年2016年寒假作业答案参考

（人教版）九年级物理2016年2016年寒假作业答案参考初中是我们人生的第一次转折，面对初中，各位学生一定要放松心情。

查字典物理网小编为大家准备了(人教版)九年级物理2016年2016年寒假作业答案参考，希望给各位学生带来帮助。

1答案：A 点拨：尘土属于小物体，它的运动属于机械运动，而不是分子的运动，B、C、D选项中均是由于分子热运动引起的，答案为A选项。

2答案：D 点拨：能够闻到酒精的气味是酒精分子不断运动的结果，所以D选项正确。

3答案：D 点拨：难以压缩表明分子间有斥力，墨水散开是由于分子运动的结果，酒精与水混合后体积变小，说明分子之间有空隙，只有D选项能说明分子间存在吸引力。

4答案：B 点拨：改变物体内能的方式有做功和热传递，A、C、D选项的能量的形式没有变化，是内能之间的转移，都是通过热传递来改变物体的内能，而B选项中，划火柴时，火柴头通过摩擦使机械能转化为火柴头的内能，使其内能增加，温度升高，达到火柴的着火点而被点燃，是能量的转化，故是通过做功改变物体的内能。

5答案：AC 点拨：冰花是室内的水蒸气遇到温度很低的玻璃发生凝华形成的，故A选项正确;空气中的水蒸气遇到雪糕周围的冷空气发生液化形成的小水滴悬浮在空气中就是所看到的“白气”，故B选项错误;将-18 ℃的冰块放在冰箱的0 ℃保鲜室中后，冰要从周围吸收热量，内能会增加，故C选项正确;用锯条锯木板时，锯条要克服摩擦做功，从而使锯条的温度升高，内能增加，这是机械能转化为内能，故D选项错误。

6答案： B 点拨：物体的温度不变，内能不一定不变，如熔化过程吸热内能增大，但温度保持不变，A选项错误;热量是热传递过程中传递的能量的多少，因此不能说物体含有热量，C选项错误;热总是从温度高的物体向温度低的物体传递，D选项错误。

7答案：B 点拨：急刹车时车胎表面温度升高，这是由于汽车克服摩擦做功，机械能转化为内能，故A不正确;分子是不断运动的，吸“二手烟”是因为分子的扩散造成的，故B正确;气压越低，水的沸点越低，说法C不正确;对市区气温有一定的调节作用，是因为水的比热容较大，故D不正确。

这不，11月份，厦门灯塔公园迎来了最大的菊花展，品种最多、数量最多，此次参展的菊花品种多达150种，总量达15万盆，令人B目不遐．接（xiá）。

“海沧大桥”、“五缘湾大桥”、“凤屿石塔”……各种标志性的现代建筑或历史文物在展出现场被一一用菊花复制。

屏展百菊的绿孔雀、菊花作鳞的九曲蟠龙、飞瀑直下的悬崖菊、老树C虬．枝（qiú）的盆景菊，还有菊花装点的风狮爷……造型景点20多个，占地1.5万平方米。

(2分）答：4、综合性学习（10分）今年三月份，国务院首次把“全民阅读”写进政府工作报告，一时间，全国掀起了一股阅读热潮。

学校决定开展以“尚阅读·扬正气”为主题的系列活动，请完成以下任务。

（1）班级举行“全民阅读”主题班会，为做好发言，某同学搜集了以下两则材料，请根据材料写出你的探究结论。

（3分）材料一：近几年，我们欣喜地看到众多民间阅览室、图书馆建成，阅读推广公益组织成长起来了，自动借书机、流动借书车、流动图书角和24小时书店在各地出现了……全国国民阅读调查数据显示，我国国民阅读率和阅读量开始持续上升。

材料二：我们也必须看到，我国的全民阅读仍处于起步阶段。

截至2013年，我国共有县以上公共图书馆3112个，人均拥有公共图书馆藏书0． 55册，这和国际标准相比，存在显著差距。

“读书无用论”等错误思潮依旧蔓延，一些书店生存艰难。

探究结论：（2）学校准备举行读书报告会，会场上要悬挂一副对联，上联已拟好，补写出下联，可根据提示的词语进行适当组合，也可自拟，使之与上联构成对偶。

（3分）上联：学习成就人生路下联：阅读（提示词：铸造助推正气魂建设中国梦精神）（3）下面是某同学在学校贴吧上发的帖子，请你跟帖。

（要求：提出自己的观点并至少用一个例子加以阐述，字数60字左右。

）（4分）某同学的帖子：读书可以养气。

腹有诗书气自华，宋濂遍观群书，则有儒雅之气；苏轼饱读诗书，则有豪放之气。

故多读则气足，气足则文华。

第二部分阅读（满分53分）三、名著阅读（9分）5.(1) 《水浒传》中很多故事脍炙人口，请从下面两个故事中任选一个，用简洁的语言概述。

（4分）斗浪里白条倒拔垂杨柳私放晁盖（2）简·爱是国女作家所著的《简·爱》中的女主人公。

（2分）（3）阅读《简·爱》中的这段文字，回答问题。

（3分）难道就因为我一贫如洗，默默无闻，长相平庸，个子瘦小，就没有剥去，没有心肠了？——你想错了？——我的心灵跟你一样丰富，我的心胸跟你一样充实！要是上帝赐予我一点姿色和充足的财富，我会使你同我现在一样难分难舍，我不是根据习俗、常规，甚至也不是血肉之躯同你说话，而是我的灵魂同你的灵魂在对话，就仿佛我们两人穿过坟墓，站在上帝脚下，彼此平等——本来就如此！这段文字中的“你”指的是谁？表现了简·爱怎样的性格？四、阅读甲乙两则文言文，完成6-9题（13分）【甲】天时不如地利，地利不如人和。

三里之城，七里之郭，环而攻之而不胜。

夫环而攻之，必有得天时者矣；然而不胜者，是时不如地利也。

城非不高也，池非不深也，兵革非不坚利也，米粟非不多也；委而去之，是地利不如人和也。

故曰，域民不以封疆之界，固国不以山溪之险，威天下不以兵革之利。

得道者多助，失道者寡助。

寡助之至，亲戚畔之；多助之至，天下顺之。

以天下之所顺，攻亲戚之所畔；故君子有不战，战必胜矣。

【乙】舜发于畎亩之中，傅说举于版筑之间，胶鬲举于鱼盐之中，管夷吾举于士，孙叔敖举于海，百里奚举于市。

故天将降大任于是人也，必先苦其心志，劳其筋骨，饿其体肤，空乏其身，行拂乱其所为，所以动心忍性，曾益其所不能。

人恒过，然后能改；困于心，衡于虑，而后作；征于色，发于声，而后喻。

入则无法家拂士，出则无敌国外患者，国恒亡。

然后知生于忧患，而死于安乐也。

9.你从乙文中领悟到什么人生哲理？（3分）五、阅读《为“小人物”的杰出喝彩》一文，完成10—13题（14分）为“小人物”的杰出喝彩①一提到杰出，很多人想到的是政治领袖、商业精英、科学巨匠等“明星级”人物。

他们确实是令人仰慕、值得学习的杰出人士。

可是今天，有另外一种“杰出”悄然走红，赢得社会各界的褒奖和追捧。

“最美司机”吴斌、“最美女教师”张丽莉……他们的职业很普通，岗位也很平凡，但在紧要关头展现出的美好品格，让道德的光芒闪耀苍穹——“小人物”的杰出同样令人动容。

②由此想到南京大学110周年庆典上引人注目的场景，那就是给“十大杰出校友”颁奖。

令人意想不到的是，获颁“杰出校友”称号的有好几位是来自基层的“小人物”。

比如王同歌，这个扎根于灌云县燕尾港默默奉献了32年的基层天气预报员就榜上有名。

南大公布的“杰出校友”首条评选标准就是“长期在基层一线尤其是在艰苦地区默默奉献，淡泊名利，在平凡岗位作出不平凡贡献的校友”。

仔细品味南大眼中的杰出，让人感慨良多。

③通往杰出的道路不止一条。

很多事物看似平淡不起眼，却不可或缺。

一根房梁，结实到极致；一个士兵，坚守住岗位。

这何尝不是杰出？雷锋一生没有干过惊天动地的事情，只是坚持把一些微不足道的小事做好，成为道德的楷模。

南丁格尔不过是一个普通的女护士，她把满腔热血都付予平凡的护理事业，成就了“提灯女神”，受到万人敬仰。

④人人都有向往杰出之心，但当社会的聚光灯集中到权势、金钱等浮华的符号上时，杰出的价值标准就容易被误读，追求杰出的路径就容易跑偏。

在“官本位”、“向钱看”观念影响下，一些人习惯于以“大官”、“大款”来论英雄、排座次、论成就，仿佛官当不到一定级别称不上杰出，财富达不到一定数量算不得杰出。

在他们眼里，官位和金钱成了衡量杰出的标准。

还有人热衷于入选各种《名人录》、《名人大全》，甚至不惜花钱买学位、买榜单。

凡此种种，都是对杰出的认知出了偏差，被名和利扰乱了心智。

照此下去，不但成不了杰出人物，反而可能跌跟头、走错路。

⑤平凡孕育杰出，杰出来自平凡。

无数事实亦证明，杰出不一定要成为大人物、名人、超人，只要老老实实做人，踏踏实实做事，小人物也完全能够杰出。

那些在基层一线、平凡岗位做出不凡业绩的人，同样是可亲、可敬又可学的杰出人物。

⑥让我们为普通人的杰出喝彩！10.本文的中心论点是什么？（2分）11.第②段运用了什么论证方法，有什么作用？（4分）12.请用简洁的语言为第③段补充一个事实论据。

（4分）13.请简述③-⑥段的论证思路。

（4分）六、阅读《向日葵》一文，完成14—17题（17分）向日葵尤今到伦敦度假，住在女儿的公寓里。

那天，约好在她下班后共进晚餐，做事有条不紊的女儿体恤地说道：“餐馆坐落在九曲十八弯的窄巷里，不太好找，你们就在餐馆附近的小公园等我吧。

”我穿了一袭宽松的棉质衣裙，没带外套。

和老公提早十分钟来到游人稀少的小公园。

天很冷，刺骨的寒风夺命也似地想把人的脸皮整层刮掉，我冷得几乎连血液也凝结了。

到了七点整，一向准时的女儿踪影不见，我们的手机偏又留在公寓里忘了带，无法联系。

寒风肆无忌惮，我冻成了冰湖底下一尾郁悒的鱼。

看着时间滴滴答答地流走，怒气像蚂蟥一样往我心里钻。

到了七点半，我的脸已幽幽地长出一层青苔。

“天气这么冷，她竟不为我们着想！”我口出怨言，“简直就是个工作狂啊！”“唉，”老公叹气，“伦敦的工作压力真是太大了！”七点四十分，女儿才气喘吁吁地赶到，连声道歉：“爸爸，妈妈，对不起，对不起！工作堆积如山，做不完呀！”我和老公对看一眼，果然不出所料！我被冻得有如一片在树梢瑟缩颤抖的枯叶，我的声音，比雪更冷：“工作做不完，不是还有明天吗？你过去守时的好习惯，去了哪里？”说着，径自往前走，不再看她一眼。

到了餐馆，女儿轻车熟路地点了各种美食。

刺身、煎和牛、鳗鱼饭、酱渍豆腐、软蟹手卷、天妇罗……可口的美食一道接一道地上，然而，我觉得心里冒出了很多冻疮，灼灼地痛，半点胃口也没有。

女儿欢欢喜喜地说着办公室里的一些趣事，我没有答腔，只一筷一筷闷闷地吃，一心只想快点回家盖上厚厚的被子蒙头大睡。

第二天，日上三竿才醒来。

薄薄扁扁的阳光从窗隙硬生生地挤了进来，看看钟，哟，九点多了！奇怪的是，厅里竟传来了女儿和她爸爸说话的声音。

我翻身起床，走出厅外，还没开口，女儿便说了：“妈妈，我今天请假。

”我讶异地问：“咦，你的工作不是堆积如山吗？”她笑嘻嘻地说：“工作做不完，不是还有明天吗？”桌上,放了一大束精神抖擞的向日葵，黄艳艳，活鲜鲜的，大蓬大蓬的热情源源不绝地释放。

向日葵旁边，有个奶油蛋糕，还有一张卡片。

卡片里，装着女儿圆润的字体：“亲爱的妈妈：记得吗？那一年，您到土耳其旅行，看到漫天漫地的向日葵，回来向我出示照片，满脸陶醉地说：那种美啊，简直惊心动魄呢！您每回看到玫瑰花、荷花和桂花，都露出馋馋的目光，想吃它们；唯独向日葵，您打从心坎里爱着它宠着它。

妈妈，我和哥哥们，其实都是您的向日葵；而您，就是我们的阳光。

”读毕，抬起头来时，女儿絮絮地说道：“妈妈，昨天下班后，我赶去办公室附近那家花店，不巧它因事休业；匆匆坐计程车去另一家，又碰上塞车，我真的急坏了呀！终于买到了您最喜欢的向日葵后，然后赶回家把它藏好，这样一来一往，才会迟到的呀！”说着，又笑眯眯地自问自答：“您猜我把花偷藏在哪儿？贮藏室！可是我又担心它难以透气，半夜起来还浇水呢！”这一天，是我的生日。
