A higher educational background exerts a tremendous fascination on a great number of people, wi

In addition, they held hard work in high regard, They understood that even geniuses have to work hard. Confronted by a setback such as a disappointing test grade,

16、 students with a growth mind-set said they would study harder or try a different strategy.

18、cusing on effort is effective in helping children overcome frustration and achieve success.【答案】C In particular, attributing poor performance to a lack of ability depresses motivation more than does the belief that lack of effort is to blame. When I told a group of school children who displayed helpl

Another group of helpless children who were simply rewarded for their success on easier problems did not improve their ability to solve harm math problems. These experiments ind

One way is by telling stories about achi

21、evements that result from hard work.

25、sider cheating on future tests.41.In the authors experiment, student with a growth mind-set showed greater perseverance in solving difficult math problems.【答案】G Such different outlook had a dramatic impact on performance. At the start of junior high, the math achievement test scores of the students

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

27、and the gap between the two groups continued to widen during the two years we followed them.42.The author conducted an experiment to find out about the influence of students mind-sets on math learning.【答案】E We validated these expectations in a study in which two other psychologists and I monitored 3

28、73 student for two years during the transition to junior high school, when the work gets more difficult and the grading more strict, to determine how their mind-sets might affect their math grades. At the beginning of seventh grade, we assessed the students mind-sets by asking them to agree or disag

29、ree with statements such as Your intelligence is something very basic about you that you cant really change. We then assessed their beliefs about other aspects of learning and looked to see what happened to their grades.43.After failing again and again, most animals give up hope.【答案】A I first began

30、to investigate the basis of human motivation-and how people persevere after setbacks-as a psychology graduate student at Yale University in the 1960s. Animal experiments by psychologists at the University of Pennsylvania had shown that after repeated failures, most animals conclude that a situation

31、is hopeless and beyond their control. After such an experience an animal often remains passive even when it can effect change-a state they called learned helplessness.44.Informing students about the brain as a learning machine is a good strategy to enhance their motivation for learning.【答案】J In addi

32、tion, parents and teachers can help children by providing explicit instruction regarding the mind as a learning machine, I designed an eight-session workshop for 91 students whose math grades were declining in their first year of junior high. Forty-eight of the students received instruction in study

33、 skills only, whereas the others attended a combination of study skills sessions and classes in which they learned about the growth mind-set and how to apply it to schoolwork. In the growth mind-set classes, students read and discussed an article entitled “You Can Grow Your Brain.” They were taught

34、that the brain is like a muscle that gets stronger with use and that learning prompts the brain to grow new connections. From such instruction, many students began to see themselves as agents of their own brain development. Despite being unaware that there were two types of instruction, teachers rep

35、orted significant motivational changes in 27% of the children in the growth mind-set workshop as compared with only 9% of students in the control group.45.People with a fixed mind-set believe that ones intelligence is unchangeable.【答案】D Later, I developed a broader theory of what separates the two g

36、eneral classes of learners-helpless versus mastery-oriented. I realized these different types of students not only explain their failures differently, but they also hold different “theories” of intelligence. The helpless ones believe intelligence is a fixed characteristic: you have only a certain am

37、ount, and thats that. I call this a fixed mind-set(思维模式).Mistakes crack their self-confidence because they attribute errors to a lack of ability, which they feel powerless to change. They avoid challenges because challenges make mistakes more likely. The mastery-orient children, on the other hand, t

38、hink intelligence is not fixed and can be developed through education and hard work. Such children believe challenges are energizing rather than intimidating (令人生畏);they offer opportunities to learn. Students with such a growth mind-set were destined(注定)for great academic success and were quite like

39、ly to outperform their counterparts.46.In the workplace, feedback may not be so welcome to managers with a fixed mind-set.【答案】H A fixed mind-set can also hinder communication and progress in the workplace and discourage or ignore constructive criticism and advice. Research shows that managers who ha

40、ve a fixed mind-set are less likely to seek or welcome feedback from their employees than are managers with a growth mind-set.Passage OneSugar, alcohol and tobacco, economist Adam Smith once wrote, are commodities which are nowhere necessaries of life, which have become objects of almost universal c

41、onsumption, and which are, therefore, extremely popular subjects of taxation.Two and a half centuries on, most countries impose some sort of tax on alcohol and tobacco. With surging obesity levels putting increasing strain on public health systems, governments around the world have begun to toy with

42、 the idea of taxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexicos taxation found a fall in purchases of taxed drinks as well as a rise in sales if untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after i

43、ts introduction, amid claims that consumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattier fare.The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry g

44、roups are under pressure to demonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount of sugar in their beverages.Many of the reductions ove

45、r the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however.Some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the foo

46、d they sell. For example, having salt on the outside, but none on the inside, 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 a multi-sided approach. The key is to remember thatthere is not just one solution

47、. To deal with obesity, a mixture of approaches-including reformulation, taxation and adjusting portion sizes-will be needed. There is no silver bullet.46.What did Adam Smith say about sugar, alcohol and tobacco.A.They were profitable to manufacture.B.They were in ever-increasing demand.C.They were

48、subject to taxation almost everywhere.D.They were no longer considered necessities of life.【答案】C47.Why have many countries started to consider taxing sugar?A.They are under growing pressures to balance their national budgets.B.They find it ever harder to cope with sugar-induced health problems.C.They practice of taxin
