Recent studies have shown that there is a link between anxiety and intelligence and it is a positive one.Fear allows you to react to a potential threat in good time.Being too happy all the time means that you don't think about potential problems.1.But the response means that their imagination is highly active.An active imagination keeps you safe from threats.

The general belief about anxiety is that it's a negative thing.Because suffering from anxiety is not pleasant,most of the people who deal with it hope they don't have to.2.Science is showing that a little bit of anxiety is a good thing.

Many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack, reduce loneliness and help control body weight.

Any pet owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress levels and blood pressure in people (half of them were pet owners) while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. People completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems that people feel more relaxed around pets, says Allen, who thinks it may be because pets don’t judge.

A study reported last fall suggests that having a pet dog may also have an effect on your body weight. Researchers at Northwestern Memorial Hospital spent a year studying two groups of fat people who were put on a diet-and-exercise program: one group with pet dogs, and the other without. On average，dog owners lost about 11 pounds，or 5% of their body weight; While those without dogs lost about 8 pounds. The pet owners, said researchers, got more exercise overall (mostly with their dogs) and found it worth doing.

1.What does the text mainly discuss?

A. People’s opinions of keeping pets.

B. How pets help people calm down.

C. What pets bring to their owners.

D. Pets can help in medical research.

2.We learn from the text that a person with heart disease has a better chance of getting well if_________.

A. he has a pet companion

B. he has less stress of work

C. he often dose mental arithmetic

D. he is taken care of by his family

3.According to Allen, why did the people do better with pets around?

A. They are less nervous.

B. They are in higher spirits.

C. They become more patient.

D. They have lower blood pressure.

4.The research mentioned in the last paragraph suggests that_________.

A. people with dogs did more exercise

B. dogs lost the same weight as people did

C. dogs liked exercise much more than people did

D. people without dogs found the program unhelpful

On average, people lost about 11 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more that 15% of their body weight. Dogs owners didn’t lose any more weight than those without dogs but, as some researchers say, they got more exercise indeed.

Aspirin has long been believed to help prevent heart attacks and strokes(中风).Some studies have shown that it also has a protective effect against certain types of cancer. As a result, some people religiously pop a low-dose(低剂量的) aspirin after breakfast every day (never take one on an empty stomach). But now its status as a wonder drug has come into question, following a meta-analysis of trial evidence.

A meta-analysis reviews the results of a large number of trials and can therefore come to more certain conclusions. This latest review was published this May in The Journal of the American Medical Association.It focused on the connection between aspirin use and cardiovascular(心血管的) and bleeding events. It found that the well-known risk that aspirin can cause internal bleeding is as great as the benefits of preventing heart attacks and strokes. In some cases, the risk even outweighs the benefits.

Aspirin thins the blood, thus helping to prevent blood clots (血栓). For his reason, it is a good drug for protecting people who have already had a heart attack or stroke from having another. However, the 164,225 people in these trials had no history of cardiovascular disease. They were monitored for an average of six years, during which time they took a daily aspirin or placebo(安慰剂).Among those who took aspirin, there were about 11% fewer heart attacks and strokes but 43% higher likelihood of a major bleeding episode in the stomach, brain or intestine(肠道).

Dr Sean Zheng, a cardiology(心脏病学) researcher at King’s College London, said that taking a daily aspirin couldn’t be recommended for healthy people. But there might still be a case for people with a higher risk of a heart attack or stroke, he added. However, it would be important to consider the bleeding risk.

“Aspirin use requires discussion between the patient and their physician, with the knowledge that any small potential cardiovascular benefits are weighed up against the real risk of severe bleeding." he said.

The findings reflect the average likelihood of bleeds or heart attacks among the patients in all the trials. There will be people among them who would be better off taking aspirin and those who will be worse. It's yet another situation where we need to weigh up our individual risk and benefit--- maybe with the help of an understanding GP.

1.Which of the following is NOT a reason why some people take an aspirin every day?

A.They want to lower their risk of having a heart attack

B.They hope to protect themselves against some cancers

C.They want to ensure they don't have a sick stomach

D.They aim to make sure they won't suffer another stroke

2.What can be concluded from the recent meta-analysis?

A.That aspirin does more harm than good to the human body

B.That aspirin frequently causes internal bleeding because it thins the blood

C.That previous research into the effects of aspirin on the human body was unreliable.

D.That taking aspirin is not worth the risk or those with no history of heart tacks or strokes.

3.What should people do before taking aspirin, according to the article?

A.To have a thorough physical examination

B.To ask for others' opinions on the internet.

C.To read the findings of new studies on aspirin

D.To talk with a doctor familiar with their condition

4.The article was probably written by ________

A.the director of a hospital

B.a public health journalist

C.the CEO of a medical company

D.a representative for an insurance company

A number of studies show that sports and other physical activities can contribute to the development of self-esteem (a feeling of pride in oneself). For example, Canadian scientists found that sixth-grade students who were more physically active had considerably higher levels of self-esteem. A study in Switzerland found that teenagers who took part in sports clubs were healthier, including being better socially adjusted, feeling less anxious, and generally being happier about their lives. Similar findings were reported in a study of Latino students, where participation in school sport was found to be greatly associated with self-esteem.

There seems little doubt that part of the potency (潜能) of sports lies in their social setting. There are a lot of facts showing the importance of social connectedness (关联性) for healthy child and teenager development, and sports offer a popular and engaging setting for social interactions. Involvement in team sports has been positively associated with social acceptance and a sense of belonging, especially where such involvement is characterized by positive coaching, progressive skill development, and peer support.

But, the social setting of sports can exclude as well as include. There is now evidence that boys’ and girls’ experiences of sports can be very different, and this can affect the contribution they can make to the self-esteem of players. Peer acceptance seems to be an important factor in determining the relationship between sport participation and self-esteem, and girls can be particularly sensitive to negative judgments. And studies have found that many ‘girly’ boys and girls benefit most from non-competitive physical activities.

So, a note of caution ought to be sounded in case sports are considered to be a cure. Much of the literature on the most positive psychological (心理的) outcomes associated with childhood and youth sports stress the absolute importance of positive experiences. It will surprise no one that bullying, excluding or abuse experiences will harm, rather than support the development of self-esteem, and well-being in general. Sadly, it will also not be a shock to learn that many children’s introductions to sports are far from improving the quality of life.

The great developmental psychologist Jean Piaget argued that the foundations of self-esteem were laid between the ages of about 6 and 11 years of age. Importantly, this is also the time when children are most likely to be introduced to sports. We should know the importance of positive early sporting experiences for the development of both self-esteem and on-going participation in sports and other physical activities. Teachers, coaches, and parents have a responsibility to ensure that these experiences ‘catch’ as many children as possible, and for this to happen they need to remember ‘the principles of child development’: Children are not mini-adults.

Problems arise when adults forget these principles, and kid themselves into thinking that they are coaching future Olympians or Super stars. Unluckily, evidence suggests that talented children are most likely to stand out when they are given time to develop, to play, and to remain children.

Children are not miniature adults, and their enjoyment of sports (and their self-esteem) can suffer when adults forget this!

1.Studies in Switzerland and Latino showed teenagers who often join in sports _____.

A.build self-esteem earlier

B.have more good experiences

C.are more sensitive to judgments

D.are healthier both physically and mentally

2.In general, the author’s attitude toward the influence of sports on teenagers is _____.

A.positive B.critical

C.uncertain D.tolerant

3.According to the author, when children take part in sports, they _____.

A.will be happier about their lives

B.are more likely to be attracted by competitive sports

C.should be treated by coaches and parents as super stars

D.will build self-esteem if given positive comment and support

4.Which of the following would be the best title for the passage?

A.Children Should Take Part in Sports

B.Sports Offer You a Better Teenage Life

C.Sports Experience and Building Self-Esteem

D.People Should Treat Teenagers Like Miniature Adults
