安徽省安工大附中高二文理科分科考试语文试题.pdf
试卷总分：150分 考试时间：150分钟 第Ⅰ卷 （阅读题 共70分） 一.（9分）阅读下面的文字，完成1～3题。
打碎窗玻璃就能促进经济增长吗 有这样一个故事：一个小孩拿起石头，打碎了商店的窗玻璃；做错了事情的孩子跑掉了，商店老板自认倒霉，拿出一笔钱去买玻璃重新安上；这下，玻璃店有了生意，赚到了一笔小钱；玻璃店店主用这笔钱去面包店买了面包，面包店又有活干了；面包店老板又去农民那里买进了一批面粉…… 仅仅是一块玻璃碎了，却带动了社会上的许多行业的发展，甚至创造了就业机会，这可真是坏事变成好事的绝佳案例！这个虚拟的案例正是经济学中一个著名的理论——破窗理论。
然而如果打碎玻璃真的能促进经济发展，为什么各国政府不鼓励所有市民集体上街，把所有的窗玻璃都打碎呢?如此一来，按照破窗理论，经济将更快速地发展，GDP也将大幅度增加。
这荒唐的一幕并没有出现，显然说明这个理论肯定有问题、有漏洞。
让我们回到玻璃打碎的那一刻，商店老板被迫花钱去买玻璃。
一个关键的问题来了：假如这笔钱不用于买玻璃，他会怎么使用呢? 从整个经济社会中看，如果商店老板那笔钱没有用到买玻璃上，而是去买药了，我们可以继续书写下面的连锁反应：药店老板赚钱了，用这笔钱去买了面包，面包店又有活干了；面包店老板又去农民那里买进了一批面粉……没错，玻璃被打碎了也好，没打碎也罢，反正只要那笔钱花了出去，都会促进各行各业的发展。
所以破窗理论不是经济理论，而是一个经济谬误。
这个谬误的产生，大概和人们误解了英国经济学家凯恩斯的理论有关。
在1929年开始的世界经济大萧条时期，凯恩斯提出，为了振兴世界经济，政府必须行动起来，甚至亲自牵头和出钱，开展修公路、修水坝等大型项目。
在经济处于低谷的时候，政府如果能适时地用资金和项目提供更多的就业机会，经济状况将逐渐好转。
凯恩斯甚至还开玩笑地说：“政府可以今天雇一批人，花钱让他们挖一些大坑；第二天政府[名校联盟]再雇一批人，花钱让他们把大坑填上。

Last week I 36 a telephone call from a woman who could not stop 37 as she told me that one of the stories in my book had saved her son from committing suicide.(自杀) In closing she called me a 38 .That 39 me thinking about what a hero really is. Was I a hero 40 I pulled a family from a burning car? If so, how could I be a hero just because I 41 a story that saved someone’s life?Today I decided to look up the word “hero”in the dictionary to see 42 what it meant. It 43 “a person who does something brave”. As I read on, it also said “ a person who is good and noble”.That statement 44 me more than the part about being 45 . So I thought about something very important. Say I was walking into the local Wal-Mart Store and I 46 to open and hold the door for someone as a courtesy (礼貌) . As they passed me by, I said, “How are you today?”Mostof the time that would be no big deal, 47 this time let’s say it was for someone who was deeply 48 and near the end of the rope.I was in such a condition after my marriage of twenty years ended. I was within hours trying to get up enough 49 to end the pain and misery. When I returned home, someone had 50 me a card in the mail which told me how 51 they would appreciate me as a friend. That wonderful card probably saved my life. That person, without even knowing it, saved a life and became a hero.Similarly many children come out of the orphanages (孤儿院) 52 a very hard and bitter attitude against the world, but the gifts we send them let them know that they have not been forgotten. 53 , most of them will never hurt anyone because of the 54 shown to them by those of us who cared.

He told me he had been the manager of a certain grocery store in the neighborhood where I grew up，and he asked me if I remembered the egg cartons (箱子).Then he related（提到）an incident and I began to remember clearly the incident he was describing.I was about eight years old at the time，and I had gone into the store with my mother to do the weekly grocery shopping. On that day，I must have found my way to the dairy (乳品的) food department where the incident took place.There must have been a special sale on eggs that day because there was an impressive display of eggs in dozen and half-dozen cartons. The cartons were stacked(堆放) three or four feet high. I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason，I decided it was up to me to put the display back together，so I went to work.The manager heard the noise and came rushing over to see what had happened. When he appeared，I was on my knees examining some of the cartons to see if any of the eggs were broken，but to him it looked as though I was the criminal（罪犯）.He severely scolded（责骂）me and wanted me to pay for any broken eggs. I protested(抗议)my innocence and tried to explain，but it did no good. Even though I quickly forgot all about the incident，obviously themanager did not.61.The author was___________when he wrote this article.A. about 8B. about 23C. about 18D. about 1562.Who should have been blamed for knocking off the stacks of cartons？A.

The purpose of writing this passage is to __________.A. ask grown-ups to visit museumsB. introduce some exhibits and museums to foreignersC. compare some museums and decide which one is the bestD. introduce some museums and encourage parents to visit them with their childrenDIf your friend and family get fat, chances are you will, too. Researchers report in a new studythat suggests obesity(肥胖) is “socially contagious(传染性的)”and can spread easily from person to person.The large, federally funded study found that to be true even if your loved ones lived far away. Social ties seemed to play a surprisingly strong role, even more than genes are known to do. “We were shocked to find that friends who are hundreds of miles away have just as much impact on a person's weight status as friends who are right next door.”Said co-author JamesFowler of the University of California, San Diego.The study found a person's chances of becoming fat went up 57 percent if a friend did, 40 percent if a sibling(兄弟姐妹) did and 37 percent if a spouse(配偶) did. Researchers think it's more than just people with similar eating and exercise habits hanging out together. Instead, it may be that having relatives and friends who become obese changes one's idea of what is an acceptable weight.Despite their findings, the researchers said people should not stop their friendships. “There is a ton of research that suggest that having more friends makes you healthier，”Fowler said.“So the last thing that you want to do is get rid of any of your friends.”The study was published in Thursday's New England Journal of Medicine and funded by the National Institute on Aging.Obesity is a global public health problem. About 1.5 billion adults worldwide are overweight, including more than 400 million who are obese. Two-thirds of Americans are either overweight or obese.Much of the recent research focus has been on the intense hunt for obesity genes involved in appetite or calorie burning. Treatment has been mainly centered on helping individuals curb(抑制) their weight through better diet and fitness. The findings could open a new way for treating this worldwide obesity. The researchers said it might be helpful to treat obese people in groups instead of just the individual.68. Treating obesity at present is mainly by ________.A. not keeping in touch with your relatives and friendsB. taking some loss-weight pillsC. going on proper diets and having right exerciseD. getting rid of obesity genes involved in appetite or calorie burning69According to the new study, obesity is “socially contagious”，which seems to be mainly caused by________.A.genesB. dietsC. living conditionsD. social ties70. What does the underlined sentence in paragraph 6 mean?A．It is unwise for us to get rid of any of our friends because of obesity.B．The best way of preventing obesity is to get rid of any of our friends.C．If we want to keep fit, we must get rid of some friends.D．We must make a good choice between obesity and friends.71. Which of the following is TRUE according to the passage?A. The new study suggests about 1.5 billion people worldwide are overweight.B. Gene is one of the factors that have something to do with obesity.C. Friendship and obesity are both of great importance.D. It might be helpful to treat obese people just as the individual instead of in groups.EAttitude is an internal(内在的) state that influences the choices of personal action made by the individual(个人). Some researchers consider that attitudes come from differences between beliefs and ideas; others believe that attitudes come from emotional states. Here, we focus on the effects of attitudes upon behavior, that is, upon the choices of action made by the individual.The kinds of actions taken by human beings are obviously influenced greatly by attitudes. Whether one listens to classical music or rock, whether one obeys the speed limit while driving, whether one encourages one’s husband or wife to express his or her own ideas-all are influenced by attitudes. These internal states are acquired(获得) throughout life from situations one is faced with in the home, in the streets, and in the school.Of course, the course of action chosen by an individual in any situation will be largely determined by the particulars of that situation. An individual who has a strong attitude of obeying laws may drive too fast when he is in a hurry and no police cars in sight. A child who has a strong attitude of honesty may steal a penny when she thinks no one will notice. But the internal state which remains unchanged over a period of time, and which makes the individual behave regularly in a variety of situations, is what is meant by an attitude.Attitudes are learned in a variety of ways. They can result from single events, as when an attitude toward snakes is acquired by an experience in childhood at the sudden movement of a snake. They can result from the individual’s experiences of success and pleasure, as when someone acquires a positive attitude toward doing crossword puzzles by being able to complete some of them. And frequently, they are learned by copying other people’s behavior, as when a child learns how to behave toward foreigners by observing the actions of his parents. Regardless of these differences, there issomething in common in the learning and modification(修正) of attitudes.72.According to the passage, attitudes .A. come from different situations in one’s lifeB. are largely affected by one’s behaviorC. remain unchanged in one’s daily lifeD. could be chosen according to one’s will73.The author uses the examples in Paragraph 3 to show .A. people often make mistakes when they are not noticedB. people with good attitudes may sometimes do bad deedsC. particulars of a situation may influence an individual’s actionD. an individual may change his or her attitude fairly easily74.Which of the following is TRUE about the learning of attitudes?A. Attitudes are only learned through one’s success.B. Attitudes learned in danger will last no more.C. Copying others’behavior is not a good idea.D. Attitudes can be learned from one’s parents.75.What would be the best title for the passage?A. Differences of Attitudes.B. Changes of Attitude.C. Choices of Attitudes.D. Nature(本质) of Attitude.第Ⅱ卷（非选择题，共35分）第四部分写作（总分35分）第一节任务型阅读（满分10分，每小题1分）阅读下面短文,根据所读内容在表格中的空白处填人最恰当的单词。
