1 . For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?

Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.

In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is—politics, the laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority—someone who actually knows something—and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.

2 . Working with a group of baboons (狒狒) in the Namibian desert, Dr. Alecia Carter of the Department of Zoology, Cambridge University set baboons learning tasks involving a novel food and a familiar food hidden in a box. Some baboons were given the chance to watch another baboon who already knew how to solve the task, while others had to learn for themselves. To work out how brave or anxious the baboons were, Dr. Carter presented them either with a novel food or a threat in the form of a model of a poisonous snake.
She found that personality had a major impact on learning. The braver baboons learnt, but the shy ones did not learn the task although they watched the baboon perform the task of finding the novel food just as long as the brave ones did. In effect, despite being made aware of what to do, they were still too shy to do what the experienced baboon did.
The same held true for anxious baboons compared with calm ones. The anxious individuals learnt the task by observing others while those who were relaxed did not, even though they spent more time watching.
This mismatch between collecting social information and using it shows that personality plays a key role in social learning in animals, something that has previously been ignored in studies on how animals learn to do things. The findings are significant because they suggest that animals may perform poorly in cognitive (认知的 ) tasks not because they aren’t clever enough to solve them, but because they are too shy or nervous to use the social information.
The findings may impact how we understand the formation of culture in societies through social learning. If some individuals are unable to get information from others because they don’t associate with the knowledgeable individuals, or they are too shy to use the information once they have it, information may not travel between all group members, preventing the formation of a culture based on social learning.

D．Some baboons perform new tasks but don’t concentrate.

4. Dr. Carter’s findings indicate that our culture might be formed through .

3 . We’ve reached a strange—some would say unusual—point. While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization (WHO), more people now die from being overweight, or say, from being extremely fat, than from being underweight. It’s the good life that’s more likely to kill us these days.
Worse, nearly 18 million children under the age of five around the world are estimated to be overweight. What’s going on?
We really don’t have many excuses for our weight problems. The dangers of the problem have been drilled into us by public ­health campaigns since 2001 and the message is getting through—up to a point.
In the 1970s, Finland, for example, had the highest rate of heart disease in the world and being overweight was its main cause. Not any more. A public ­health campaign has greatly reduced the number of heart disease deaths by 80 per cent over the past three decades.
Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005, and doctors even offer surgery of removing fat inside and change the shape of the body. That has become a sort of fashion. No wonder it ranks as the world’s most body ­conscious country.
We know what we should be doing to lose weight—but actually doing it is another matter. By far the most popular excuse is not taking enough exercise. More than half of us admit we lack willpower.
Others blame good food. They say: it’s just too inviting and it makes them overeat. Still others lay the blame on the Americans, complaining that pounds have piled on thanks to eating too much American­ style fast food.
Some also blame their parents—their genes. But unfortunately, the parents are wronged because they’re normal in shape, or rather slim.
It’s a similar story around the world, although people are relatively unlikely to have tried to lose weight. Parents are eager to see their kids shape up. Do as I say—not as I do.

4 .         A German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse.

The paper, published this March in Psychology and Aging, examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96. The surveys were conducted every year from 1993 to 2003.

Survey respondents were asked to estimate their present and future life satisfaction on a scale of 0 to 10, among other questions.

The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction, while middle-aged adults (age 40 to 64) more accurately predicted how they would feel in the future. Adults of 65 and older, however, were far more likely to underestimate their future life satisfaction. Not only did they feel more satisfied than they thought they would, the older pessimists seemed to suffer a lower ratio of disability and death for the study period.

“We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade,” wrote Frieder R. Lang, a professor at the University of Erlangen-Nuremberg.

Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future.

“Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions (预防措施),” the authors wrote.

Surprisingly, compared with those in poor health or who had low incomes, respondents who enjoyed good health or income were associated with expecting a greater decline. Also, the researchers said that higher income was related to a greater risk of disability.

The authors of the study noted that there were limitations to their conclusions. Illness, medical treatment and personal loss could also have driven health outcomes.

However, the researchers said a pattern was clear. “We found that from early to late adulthood, individuals adapt their expectations of future life satisfaction from optimistic, to accurate, to pessimistic,” the authors concluded.

1. According to the study, who made the most accurate prediction of their future life satisfaction?

A．Optimistic adults.

B．Middle-aged adults.

3. How do people of higher income see their future?

A．They will earn less money.

B．They will become pessimistic.
