9、en in one of the paragraphs. Identify the paragraphfrom which the information is derived. You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking thecorresponding letter on Answer Sheet 2.The Secret to Raising Smart KidsA) I first began to inv

10、estigate the basis of human motivation-and how people persevere aftersetbacks-as a psychology graduate student at Yale University in the 1960s. Animal experiments bypsychologists at the University of Pennsylvania had shown that after repeated failures, most animalsconclude that a situation is hopele

11、ss and beyond their control. After such an experience an animaloften remains passive even when it can effect change-a state they called learned helplessness.B) People can learn to be helpless, too. Why do some students give up when they encounter difficulty,whereas others who are no more skilled con

12、tinue to strive and learn? One answer, I soondiscovered, lay in peoples beliefs about why they had failed.C) In particular, attributing poor performance to a lack of ability depresses motivation more than doesthe belief that lack of effort is to blame. When I told a group of school children who disp

13、layedhelpless behavior that a lack of effort led to their mistakes in math, they learned to keep tryingwhen the problems got tough. Another group of helpless children who were simply rewarded fortheir success on easier problems did not improve their ability to solve hard math problems. Theseexperime

14、nts indicated that a focus on effort can help resolve helplessness and generate success.D) Later, I developed a broader theory of what separates the two general classes of learners-helplessversus mastery-oriented. I realized these different types of students not only explain their failuresdifferentl

15、y, but they also hold different theories of intelligence.The helpless ones believeintelligence is a fixed characteristic: you have only a certain amount, and thats that. I call this afixed mind-set (思维模式). Mistakes crack their self-confidence because they attribute errors toa lack of ability, which

16、they feel powerless to change. They avoid challenges because challengesmake mistakes more likely. The mastery-oriented children, on the other hand, think intelligence isnot fixed and can be developed through education and hard work. Such children believe challengesare energizing rather than intimida

17、ting (令人生畏); they offer opportunities to learn. Studentswith such a growth mind-set were destined (注定) for greater academic success and were quitelikely to outperform their counterparts.E) We validated these expectations in a study in which two other psychologists and I monitored 373students for two

18、 years during the transition to junior high school, when the work gets more difficultand the grading more strict, to determine how their mind-sets might affect their math grades. At thebeginning of seventh grade, we assessed the students mind-sets by asking them to agree or disagreewith statements s

19、uch as Your intelligence is something very basic about you that you cant reallychange. We then assessed their beliefs about other aspects of learning and looked to see whathappened to their grades.F) As predicted, the students with a growth mind-set felt that learning was a more important goal thang

20、etting good grades. In addition, they held hard work in high regard. They understood that evengeniuses have to work hard. Confronted by a setback such as a disappointing test grade, studentswith a growth mind-set said they would study harder or try a different strategy. The students whoheld a fixed

21、mind-set, however, were concerned about looking smart with less regard for learning.They had negative views of effort, believing that having to work hard was a sign of low ability.They thought that a person with talent or intelligence did not need to work hard to do well.Attributing a bad grade to t

22、heir own lack of ability, those with a fixed mind-set said that they wouldstudy less in the future, try never to take that subject again and consider cheating on future tests.G) Such different outlooks had a dramatic impact on performance. At the start of junior high, the mathachievement test scores

23、 of the students with a growth mind-set were comparable to those ofstudents who displayed a fixed mind-set. But as the work became more difficult, the students witha growth mind-set showed greater persistence. As a result, their math grades overtook those of theother students by the end of the first

24、 semester-and the gap between the two groups continued towiden during the two years we followed them.H) A fixed mind-set can also hinder communication and progress in the workplace and discourage orignore constructive criticism and advice. Research shows that managers who have a fixed mind-setare le

25、ss likely to seek or welcome feedback from their employees than are managers with a growthmind-set.I) How do we transmit a growth mind-set to our children? One way is by telling stories aboutachievements that result from hard work. For instance, talking about mathematical geniuses whowere more or le

26、ss born that way puts students in a fixed mind-set, but descriptions of greatmathematicians who fell in love with math and developed amazing skills produce a growth mind-set.J) In addition, parents and teachers can help children by providing explicit instruction regarding themind as a learning machi

27、ne. I designed an eight-session workshop for 91 students whose mathgrades were declining in their first year of junior high.Forty-eight of the students receivedinstruction in study skills only, whereas the others attended a combination of study skills sessionsand classes in which they learned about

28、the growth mind-set and how to apply it to schoolwork. Inthe growth mind-set classes, students read and discussed an article entitled You Can Grow YourBrain. They were taught that the brain is like a muscle that gets stronger with use and thatlearning prompts the brain to grow new connections. From

29、such instruction, many students beganto see themselves as agents of their own brain development. Despite being unaware that there weretwo types of instruction, teachers reported significant motivational changes in 27% of the childrenin the growth mind-set workshop as compared with only 9% of student

30、s in the control group.K) Research is converging (汇聚) on the conclusion that great accomplishment and even genius istypically the result of years of passion and dedication and not something that flows naturally from agift.36. The authors experiment shows that students with a fixed mind-set believe h

31、aving to work hard is an indication of low ability.37. Focusing on effort is effective in helping children overcome frustration and achieve success.38. We can cultivate a growth mind-set in children by telling success stories that emphasize hard work and love of learning.39. Students belief about th

32、e cause of their failure explains their attitude toward setbacks.40. In the authors experiment, students with a growth mind-set showed greater perseverance in solving difficult math problems.41. The author conducted an experiment to find out about the influence of students mind-sets on math learning

33、.42. After failing again and again, most animals give up hope.43. Informing students about the brain as a learning machine is a good strategy to enhance their motivation for learning.44. People with a fixed mind-set believe that ones intelligence is unchangeable.45. In the workplace, feedback may no

34、t be so welcome to managers with a fixed mind-set.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions orunfinished statements. For each of them there are four choices marked A., B., C. AndD . You should decide on the best choice and mark the correspo

35、nding letter on AnswerSheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Sugar, alcohol and tobacco, economist Adam Smith once wrote, are commodities which arenowhere necessaries of life, which have become objects of almost universal consum

Withsurging obesity levels putting increasing strain on public health systems, governments around the worldhave begun to toy with the id

37、ea of taxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexicos taxation found afall in purchases of taxed drinks as well as a rise in sales of untaxed and healthier drinks. By contrast,a Danish tax on foods high in fats was abandoned a year after its introd

38、uction, amid claims thatconsumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattierfare.The food industry has, in general, been firmly opposed to such direct government action.Nonetheless, the renewed focus on waistlines means that industry groups are un

39、der pressure todemonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of itsofferings. For example, some drink manufacturers have cut the amount of sugar in their beverages.Many of the reductions over the past 30

40、 years have been achieved either by reducing the amount ofsugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however, somecompanies have been investing money in a more ambitious undertaking: learning how to adjust thefundamental make-up of the food they sell. Fo

41、r example, having salt on the outside, but none on theinside, reduces the salt content without changing the taste.While reformulating recipes ( 配方) is one way to improve public health, it should be part of amulti-sided approach. The key is to remember that there is not just one solution. To deal wit

What is the more recent effort by food companies to make foods and drinks both healthy and tasty?A. Replacing sugar or salt with alternative ingredients.B. Setting a limit on th

46、e amount of sugar or salt in their products.C. Investing in research to find ways to adapt to consumers needs.D. Adjusting the physical composition of their products.50. What does the author mean by saying, at the end of the passage, There is no silver bullet ( Line 4, Para.7)?A. There is no single

47、easy quick solution to the problem.B. There is no hope of success without public cooperation.C. There is no hurry in finding ways to solve the obesity problem.D. There is no effective way to reduce peoples sugar consumption.Passage TwoQuestions 51 to 55 are based on the following passage.You may hav
