高考真题——语文(上海卷)Word版 含答案
全国普通高等学校招生统一考试（一）上海语文试卷一阅读 80分（一）阅读下文，完成1—6题。
（18分）受众的新闻素养：能力和意愿①新闻作为一种媒体信息，本应有助于人们了解事情的真相，如信息论的提出者香农就曾把信息定义为“不确定性的消除”，然而信息也会增加人们对真相认识的不确定性。
尤其在这个信息爆炸的时代，如何摆脱这种困境？除了优化信息环境外，更现实的途径是提高受众的新闻素养。
②在信息时代，批判性地解读和使用媒体信息应是社会成员的基本技能。
为什么在今天要特别强调受众的“新闻素养”？这是由新闻的性质和当今新闻的发展趋势决定的。
新闻是帮助公民自治的必要信息，和其他出于私人利益或兴趣而获得的信息不同，它关乎社会群体的公共利益，最终会影响私人生活。
而随着信息技术的发展、商业文化的介入、新闻发布门槛的降低，新闻与评论、娱乐、宣传的界线不再像从前那样清晰，“准新闻”甚至“伪新闻”层出不穷。
③新闻受众应该提高自己的新闻辨别能力，对不同来源的信息设置不同的警惕值，这样才能使自己变得明智。
如何批判性地解读新闻？受众可以从以下几个方面加以考虑：1、报道有无确切的来源？来源可靠吗？2、报道的内容完整吗？是否包含事件的时间、地点、人物、原因、经过等要素？假如不完整，原因是什么？3、报道者提供了什么证据？这些证据是怎样检验或核实的？4、这则新闻除了报道事件外，是否还有其他意图？④有人认为受众都是愿意看到真相的，他们欠缺的仅仅是辨别能力，然而现实中相当多的受众首先欠缺的是寻求事实真相的意愿。
如果说从前的新闻受众在接收信息上缺乏自由的话，那么现在的新闻受众更多是被诱惑，把有限的时间用于关注娱乐新闻，而最危险的是在被抑制和被诱导中养成的对事实真相无所谓的态度，要么是“你知道了真相又能怎样”，要么是“根本就没有真相，一切都是阴谋”。
前者导致老于世故地配合做戏，后者导致愤世嫉俗、拒绝相信一切。
⑤还有一些人尽管有寻求事实真相的意愿，却习惯于把常识当成真相，或者以常识为来判断事件是否真实。

Each word can only be used once. Note that there is one word more than you need.Let's say you've decided you want to eat more healthfully. However, you don't have time to carefully plan menus for meals or read food __41__ at the supermarket. Since you really__42__ yourself to a healthier lifestyle, a little help would come in handy, wouldn't it? This is where a "choice architect" can help__43__some of the burden of doing it all yourself. Choice architects are people who organize the contexts in which customers make decisions. For example, the person who decides the layout of your local supermarket-including which shelf the peanut butter goes on, and how the oranges are piled up—is a choice architect.Governments don't have to__44__healthier lifestyles through laws for example, smoking bans. Rather, if given an environment created by a choice architect-one that encourages us to choose what is best-we will do the right things. In other words, there will be designs that gently push customers toward making healthier choices, without removing freedom of choice. This idea combines freedom to choose with__45__hints from choice architects, who aim to help people live longer, healthier, and happier lives.The British and Swedish governments have introduced a so-called "traffic light system" to __46__foods as healthy or unhealthy. This means that customers can see at a glance how much fat,sugar, and salt each product contains__47__by looking at the lights on the package. A green light __48__that the amounts of the three nutrients are healthy; yellow indicates that the customer should be__49__; and red means that the food is high in at least one of the three nutrients and should be eaten in __50__. The customer is given important health information, but is still free to decide what to choose.III. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Research has shown that two-thirds of human conversation is taken up not with discussion of the cultural or political problems of the day, not heated debates about films we've just watched or books we've just finished reading, but plain and simple __51__.Language is our greatest treasure as a species, and what do we __52__ do with it? We gossip. About others' behavior and private lives, such as who's doing what with whom, who's in and who's out-and why; how to deal with difficult __53__ situations involving children, lovers, and colleagues.So why are we keen on gossiping? Are we just natural __54__, of both time and words? Or do we talk a lot about nothing in particular simply to avoid facing up to the really important issues of life? It's not the case according to Professor Robin Dunbar. In fact, in his latest book, Grooming, Gossip and the Evolution of Language, the psychologist says gossip is one of these really__55__issues.Dunbar __56__ the traditional view that language was developed by the men at the early stage of social development in order to organize their manly hunting activities more effectively, or even to promote the exchange of poetic stories about their origins and the supernatural. Instead he suggests that language evolved among women. We don't spend two-thirds of our time gossiping just because we can talk, argues Dunbar—__57__, he goes on to say, language evolved specifically to allow us to gossip.Dunbar arrived at his cheery theory by studying the __58__ of the higher primates（灵长类动物）like monkeys. By means of grooming--cleaning the fur by brushing it, monkeys form groups with other individuals on whom they can rely for support in the event of some kind of conflict within the group or__59__ from outside it.As we human beings evolve from a particular branch of the primate family, Dunbar __60__ that at one time in our history we did much the same. Grouping together made sense because the bigger the group, the greater the __61__ it provided; on the other hand, the bigger the group, the greater the stresses of living close to others. Grooming helped to __62__ the pressure and calm everybody down.But as the groups got bigger and bigger, the amount of time spent in grooming activities also had to be __63__ to maintain its effectiveness. Clearly, a more __64__ kind of grooming was needed, and thus language evolved as a kind of vocal（有声的）grooming which allowed humans to develop relationship with ever-larger groups by exchanging information over a wider network of individuals than would be possible by one-to-one __65__ contact.51.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Most people agree that honesty is a good thing. But does MotherNature agree? Animals can't talk, but can they lie in other ways? Can theylie with their bodies and behavior? Animal experts may not call it lying,but they do agree that many animals, from birds to chimpanzees, behavedishonestly to fool other animals. Why? Dishonesty often helps themsurvive.Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator（猎食动物）gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the "hurt" adult, leaving the baby birds safe in the nest.Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them,and they don't need to share their food.As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.66. A plover protects its young from a predator by______.A. getting closer to its youngB. driving away the adult predatorC. leaving its young in another nestD. pretending to be injured67. By "Chimpanzees, or chimps, can also be sneaky" (paragraph 5), the author means______.A. chimps are ready to attack othersB. chimps are sometimes dishonestC. chimps are jealous of the winnersD. chimps can be selfish too68. Which of the following is true according to the passage?A. Some chimps lower their cry to keep food away from others.B. The losing chimp won the fight by taking the winner's hand.C. Cuckoos fool their adoptive parents by making no nests.D. Some clever scrub jays often steal their food back.69. Which of the following might be the best title of the passage?A. Do animals lie?B. Does Mother Nature fool animals?C. How do animals learn to lie?D. How does honesty help animals survive?(B)Let's say you want to hit the gymmore regularly this year. How doyou make that happen? Considerputting the habit loop to use.Here's how it works:A habit is a 3-step process. First,there's a cue, something that tellsyour brain to operate automatically.Then there's a routine. And finally, areward, which helps your brainlearn to desire the behavior. It'swhat you can use to create-orbreak-habits of your own.Here's how to apply it:Choose a cue, like leaving yourrunning shoes by the door, then pick.a reward-say, a piece of chocolatewhen you get home from the gym.That way, the cue and the rewardbecome interconnected. Finally,when you see the shoes, your brainwill start longing for the reward,which will make it easier to workout day after day. The best part? Ina couple of weeks, you won't needthe chocolate at all. Your brain willcome to see the workout itself asthe reward. Which is the wholepoint, right?70. Which of the following best fitsin the box with a “?” in THEHABIT LOOP?A. Pick a new cue.B. Form a new habit.C. Choose a new reward.D. Design a new resolution.71. According to THE HABIT LOOP, you can stick to your plan most effectively by______.A. changing the routineB. trying it for a weekC. adjusting your goalD. writing it down72. What's the purpose of putting the habit loop to use?A. To test out different kinds of cues.B. To do something as a habit even without rewards.C. To work out the best New Year's resolution.D. To motivate yourself with satisfactory rewards.73. “This year when I see the Harry Potter poster, I will read 30 pages of an English novel or anEnglish newspaper in order to watch TV for half an hour." What is the cue in this resolution?A. The Harry Potter poster.B. Reading 30 pages of an English novel.C. An English newspaper.D. Watching TV for half an hour.(C)If you could be anybody in the world, who would it be? Your neighbour or a super star? A few people have experienced what it might be like to step into the skin of another person, thanks to an unusual virtual reality（虚拟现实）device. Rikke Wahl, an actress, model and artist, was one of the participants in a body swapping experiment at the Be Another lab, a project developed by a group of artists based in Barcelona. She swapped with her partner, an actor, using a machine called The Machine to Be Another and temporarily became a man. "As I looked down, I saw my whole body as a man, dressed in my partner's pants," she said. "That's the picture I remember best."The set-up is relatively simple. Both users wear a virtual reality headset with a camera on the top. The video from each camera is sent to the other person, so what you see is the exact view of your partner. If she moves her arm, you see it. If you move your arm, she sees it.To get used to seeing another person's body without actually having control of it, participants start by raising their arms and legs very slowly, so that the other can follow along. Eventually, this kind of slow synchronised（同步的）movement becomes comfortable, and participants really start to feel as though they are living in another person's body.Using such technology promises to alter people's behaviour afterwards-potentially for the better. Studies have shown that virtual reality can be effective in fighting racism-the bias（偏见）that humans have against those who don't look or sound like them. Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test, which measures the strength of people's associations between, for instance, black people and adjectives such as good, bad, athletic or awkward. Then they asked them to control the body of a dark skinned digital character using virtual reality glasses, before taking the test again. This time, the participants' bias scores were lower. The idea is that once you've "put yourself in another's shoes" you're less likely to think ill of them, because your brain has internalised the feeling of being that person.The creators of The Machine to Be Another hope to achieve a similar result. "At the end of body swapping, people feel like holding each other in their arms," says Arthur Pointeau, a programmer with the project. "It's a really nice way to have this kind of experience. I would really, really recommend it to everyone."74. The word "swapping" (paragraph 1) is closest in meaning to______.A. buildingB. exchangingC. controllingD. transplanting75. We can infer from the experiment at the Be Another lab that______.A. our feelings are related to our bodily experienceB. we can learn to take control of other people's bodiesC. participants will live more passionately after the experimentD. The Machine to Be Another can help people change their sexes76. In the Implicit Association Test, before the participants used virtual reality glasses to control adark skinned digital character, ______.A. they fought strongly against racismB. they scored lower on the test for racismC. they changed their behaviour dramaticallyD. they were more biased against those unlike them77. It can be concluded from the passage that______.A. technology helps people realize their dreamsB. our biases could be eliminated through experimentsC. virtual reality helps promote understanding among peopleD. our points of view about others need changing constantlySection CDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.More and more corporations are taking an interest in corporate social responsibility (CSR). CSR is made up of three broad layers. The most basic is traditional corporate charity work. Companies typically spend about 1% of pre-tax profits on worthy projects. But many feel that simply writing cheques to charities is no longer enough. In some companies, shareholders want to know that their money is being put to good use, and employees want to be actively involved in good works.Money alone is not the answer when companies come under attack for their behavior. Hence the second layer of CSR, which is a branch of risk management. Starting in the 1980s, with environmental disasters such as the explosion at Bhopal and the Exxon V aldez oil spill, industry after industry has suffered blows to its reputation.So, companies often responded by trying to manage the risks. They talk to non-governmental organisations (NGOs) and to governments, create codes of conduct（行为准则) and devote themselves to more transparency（透明）in their operations. Increasingly, too. they, along with their competitors, set common rules to spread risks.All this is largely defensive, but there are also opportunities for those that get ahead of the game. The emphasis on opportunity is the third layer of CSR: the idea that it can help to create value. If approached in a strategic way, CSR could become part of a company's competitive advantage. That is just the sort of thing chief executives like to hear. The idea of "doing well by doing good" has become popular.Nevertheless, the business of trying to be good is bringing difficult questions to executives. Can you measure CSR performance? Should you be cooperating with NGOs and you’re your competitors? Is there any really competitive advantage to be had from a green strategy?Corporate social responsibility is now seen as a mainstream. Big companies want to tell the world about their good citizenship with their devotion to social responsibilities. Done badly, CSR is often just window-dressing and can be positively harmful. Done well, though, it is not someseparate activity that companies do on the side, a corner of corporate life reserved for virtue（美德）：it is just good business.(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS)78. Both _________ in some companies find it no longer enough to simply donate money to charities.79. Give one example of the defensive measures of risk management according to the passage.80. With the emphasis on opportunity, the third layer of CSR is meant to_________.81. According to the passage, "good business" (paragraph 6) means that corporations ________ while making profits.第II卷（共47分）I.
