　　The Secret to Raising Smart Kids

author's experiment shows that students with a fixed mind-set believe having to work hard is an indication of low ability.

【答案】[F] As predicted, the students with a growth mind-set felt that learning was more important goal than getting good grades. 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, students with a growth mind-set said they would study harder or try a different strategy. The students who held a fixed 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 their own lack of ability, those with a fixed mind-set said that would study less in the future, try never to take that subject again and consider cheating on future tests.

sing 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 helpless behavior that a lack of effort led to their mistakes in math, they learned to keep trying when the problems got tough. 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 indicated that a focus on effort can help resolve helplessness and generate success.

can cultivate a growth mind-set in children by telling success stories that emphasize hard work love of learning.

【答案】[I] How do we transmit a growth mind-set to our children? One way is by telling stories about achievements that result from hard work. For instance, talking about mathematical geniuses

Who were more or less born that way puts students in a fixed mind-set, but mathematicians who fell in love with math and developed amazing skills produce a growth mind-set.

ents’ belief about the cause of their failure explains their attitude toward setbacks.

【答案】[F]As predicted, the students with a growth mind-set felt that learning was more important goal than getting good grades. 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, students with a growth mind-set said they would study harder or try a different strategy. The students who held a fixed mind-set, however, were concerned about looking smart with less regard for learning.

Attributing a bad grade to their own lack of ability, those with a fixed mind-set said that would study less in the future, try never to take that subject again and consider cheating on future tests.

the author’s 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 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-and the gap between the two groups continued to widen during the two years we followed them.

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 373 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 disagree with statements such as "Your intelligence is something very basic about you that you can't really change." We then assessed their beliefs about other aspects of learning and looked to see what happened to their grades.

r failing again and again, most animals give up hope.

【答案】[A] I first began 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 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.

rming students about the brain as a learning machine is a good strategy to enhance their motivation for learning.

【答案】[J] In addition, 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 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 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 reported 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.

le with a fixed mind-set believe that one’s intelligence is unchangeable.

【答案】[D] Later, I developed a broader theory of what separates the two general 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 amount, and that's 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, think 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 likely to outperform their counterparts.

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 have a fixed mind-set are less likely to seek or welcome feedback from their employees than are managers with a growth mind-set.

　　Part Ⅲ Reading Section C(卷二)

　　Passage One

"Sugar, alcohol and tobacco," economist Adam Smith once wrote, "are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, 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 the idea of taxing sugar as well.

Whether such taxes work is a matter of debate. A preliminary review of Mexico's 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 its 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 groups 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 over 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 food 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 that

there is not just one solution. To deal with obesity, a mixture of approaches-including reformulation, taxation and adjusting portion sizes-will be needed. There is no silver bullet.

did Adam Smith say about sugar, alcohol and tobacco.

were profitable to manufacture.

were in ever-increasing demand.

were subject to taxation almost everywhere.

were no longer considered necessities of life.

【答案】C

have many countries started to consider taxing sugar?

are under growing pressures to balance their national budgets.

find it ever harder to cope with sugar-induced health problems.

practice of taxing alcohol and tobacco has proved both popular and profitable.

sugar industry is overtaking alcohol and tobacco business in generating profits.

【答案】B

do we learn about Danish taxation on fat-rich foods?

did not work out as well as was expected.

gave rise to a lot of problems on the border.

could not succeed without German cooperation.

met with firm opposition from the food industry.

【答案】A

is the more recent effort by food companies to make foods and drinks both healthy and tasty?

acing sugar or salt with alternative ingredients.

ing a limit on the amount of sugar or salt in their products.

sting in research to find ways to adapt to consumers' needs.

sting the physical composition of their products.

【答案】D

does the author mean by saying, at the end of the passage, "There is no silver bullet"(Line 4, Para 7)?

e is no single easy quick solution to the problem.

e is no hope of success without public cooperation.

e is on hurry in finding ways to solve the obesity problem.

e is no effective way to reduce people's sugar consumption.

【答案】A

　　Passage Two

You may have heard some of the fashion industry horror stories: models eating tissues or cotton balls to hold off hunger, and models collapsing from hunger-induced heart attacks just seconds after they step off the runway.

Excessively skinny models have been a point of controversy for decades, and two researchers say a model's body mass should be a workspace health and safety issue. In an editorial released Monday in the American Journal of Public Health, Katherine Record and Bryn Austin made their case for government regulation of the fashion industry.

The average international runway model has a body mass index (BMI) under 16-low enough to indicate starvation by the World Health Organization's standard. And Record and Austin are worried not just about the models themselves, but about the vast number of girls and women their images influence.

"Especially girls and tens", says Record. "Seventy percent of girls aged 10 to 18 report that they define perfect body image based on what they see in magazines." That's especially worrying, she says, given that anorexia(厌食症)results in more deaths than does any other mental illness, according to the National Institute of Mental Health.

It's commonly known that certain diseases are linked with occupations like lung disease in coal miners. Professional fashion models are particularly vulnerable to eating disorders resulting from occupational demands to maintain extreme thinness.

Record's suggestion is to prohibit agents from hiring models with a BMI below 18.

In April, France passed a law setting lower limits for a model's weight. Agents and fashion houses who hire models with BMI under 18 could pay $82,000 in fines and spend up to 6 months in jail. Regulating the fashion industry in the United States won't be easy, Record says. But with the new rules in France, U.S. support could make a difference. "A designer can't survive without participating in Paris Fashion Week", she says, adding, "Our argument is that the same would be true of New York Fashion Week."

do Record and Austin say about fashion models' body mass?

has caused needless controversy.

is focus of the modeling business.

is but a matter of personal taste.

affects models' health and safety.

【答案】D

are Record and Austin advocating in the Monday editorial?

A.A change in the public's view of female beauty.

rnment legislation about models' weight.

ination of forced weight loss by models.

ibition of models eating non-food stuff.

【答案】B

are Record and Austin worried about the low body mass index of models?

contributes to many mental illnesses.

defines the future of the fashion industry.

has great influence on numerous girls and women.

keeps many otherwise qualified women off the runaway.

【答案】C

54. What do we learn about France's fashion industry?

has difficulty hiring models.

has now a new law to follow.

allows girls under 18 on the runway.

has overtaken that of the United States.

【答案】B

55. What does Record expect of New York Fashion Week?

will create a completely new set of rules.

will do better than Paris Fashion Week.

will differ from Paris Fashion Week.

will have models with a higher BMI.

【答案】D
