British researchers have found that children’s IQ predicts their probability of becoming vegetarians (素食者) as young adults.
Recent studies suggest that vegetarianism may be associated with lower cholesterol (膽固醇), reduced risk of overweight and heart disease.
“We know from other studies that brighter children tend to behave in a healthier fashion as adults—they’re less likely to smoke, less likely to be overweight，less likely to have high blood pressure and more likely to take exercise.” lead author Catharine Gale said, “This study provides further evidence that people  with a high IQ tend to have a healthier lifestyle.”
In the study, Gale’s team collected data on nearly 8,200 men and women aged 30, whose IQ had been tested when they were 10 years of age.
“Children who scored higher on IQ tests at age 10 were more likely than those who got lower scores to report that they were vegetarian at the age of 30.”Gale said. 
The researchers found that 4.5 percent of participants were vegetarians. Of these, 2.5 percent were vegan, and 33.6 percent said they were vegetarian but also ate fish or chicken.
There was no difference in IQ score between strict vegetarians and those who said they were vegetarian but also ate fish or chicken，the researchers added.
One expert said the findings weren’t the whole answer，however.
“We don’t know the beliefs or attitudes of the parents of the children，nor do we know if there was a particular event that led these children to becoming vegetarian in their teens or adulthood.” said Lona Sandon, and assistant professor at the University of Texas Southwestern Medical Center at Dallas.

American children are not the only couch potatoes with nearly one third of children globally spending 3 hours a day or more watching TV or on computers, according to the study of over 70,000 teens in 34 nations.
From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children were not getting enough exercise and that it made no difference whether they live in a rich or a poor country. “With regards to physical levels, we didn’t find much of a difference between rich and poor countries,” Guthold said, “Growing up in a poor country doesn’t necessarily mean kids get more physical activities.”
The researchers defined adequate physical activity as at least an hour of exercise outdoors for at least 5 days a week. Children spending 3 or more hours a day watching TV, playing computer games or chatting with friends were classified as sedentary.
The researchers found only a quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions. A quarter of boys and nearly 30% of girls were sedentary and didn’t get enough exercise with girls less active than boys in every country aside from Zambia.
Girls from India were the most active with 37 percent meeting exercise recommendation, while girls from Egypt were the least active with 4 percent getting enough exercise. Children in Myanmar were the least sedentary while the most sedentary nations were St .Lucia and the Cayman Islands.
People show deep concern for kids’ lack of physical activity in various nations. Why do they have a low level of physical activity? Guthold speculated（認(rèn)為）that urbanization could be a factor as well as easy access to cars and TVs.
【小題1】If you are sedentary, you ____________.   

A．a(chǎn)re a diligent student spending much time doing homework
B．have at least an hour of exercise outdoors 5 days a week.
C．like watching TV and playing computer games

【小題2】Which of the following statements is true as to Guthold’s finding?
A．Most children around the world don’t meet the exercise recommendation.
B．Girls in every country are no more active than boys.
C．Children in rich countries relatively get less physical activity.
D．Only 4% of the girls from Egypt are not active in exercise.

A．Children in poor countries get more physical activities.
B．Girls in Egypt are more active than those in India.
C．Couch potatoes are those children addicted to snacks.
D．Children in Myanmar are less sedentary than those in St .Lucia.
【小題4】What would the writer be most likely to discuss in detail in the paragraph that follows?

How often do you sit still and do absolutely nothing? The usual answer these days is“never” or “hardly ever”. As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life. There is no way to avoid it, since it takes many and varied forms-driving in traffic, problems with personal relationships are all different forms of stress. Stress, in fact, is not the “baddy” it is often reputed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first sight of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make a choice between “fight” or “fright” and in more primitive days the choice made the difference between life and death. The crisis we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. All the energy is shifted to cope with the stress. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress.
Stress in some people produces stomach disorders, while others experience tension headaches. Since we cannot remove stress from our 1ives, We need to find ways to cope with it.

Healthy people with stressful jobs who work long hours but get little satisfaction from what they do have twice the risk of dying from heart disease as satisfied employees, according to a study. Job stress has been known to cause heart problems in people who already have cardiovascular disease (心血管病). Finnish scientists have now shown that even in healthy people the pressures of work can take their toll. High blood pressure, lack of exercise, smoking and being overweight contribute to heart disease—a leading killer in many industrialized countries.
But Mika Kivimaki, of the Finnish Institute of Occupational Health, and his colleagues, who studied the medical histories of 812 healthy Finnish men and women in a metal industry company over 25 years, said job stress also plays an important role.
Workers who had the highest job-related stress levels at the start of the study were more than twice as likely to die of heart disease, according to the study published in The British Medical Journal. Work stress involves too much work as well as a lack of satisfaction and feeling undervalued and unappreciated. Many people work long hours but if the effort is rewarding the stress is minimized.
The British Heart Foundation said the results support earlier research showing that people in jobs with low control, such as manual(體力的) workers, could be as great risk of heart disease than other employees. “ It is advisable for people to try to minimize levels of stress at work and for employees to allow people to have more control at work and to be rewarded for their successes,” the foundation said in a statement.
【小題1】Healthy people may die from heart disease of ____________.

A．too much job stress B．working too hard C．feeling valued D．being satisfied
【小題2】Which one of the following is NOT right according to this passage?
A．High blood pressure is likely to cause heart disease.
B．Being overweight may cause heart disease.
C．Job stress is most likely to cause heart disease.
D．Working long hours must cause heart disease.
【小題3】The underlined word “minimized” in the third paragraph means “_________”.
A．increased B．reduced C．raised D．cured
【小題4】The author’s purpose in writing the passage is to _________.
A．a(chǎn)dvise people not to work long hours
B．suggest that everyone be satisfied with everything
C．a(chǎn)sk us to learn to enjoy ourselves
D．tell us that job stress threatens our health nowadays.

Our risk of cancer rises rapidly as we age. So it makes sense that the elderly should be routinely screened for new tumors (腫瘤) or doesn’t it?
While such tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it s important to weigh the health benefits of screening against the risks and costs of routine testing.
In many cases, screening can lead to additional examinations and operations to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not cause serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained (根深蒂固的) that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a noisy reaction among doctors, patients and social groups.
It’s hard to uproot deeply-held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or previous personal experience with the disease, should continue to get screened regularly. But for the rest, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy.
A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening—especially considering the explosion of the elderly.
It’s not an easy calculation to make, but one that makes sense for patients. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves from medical disputes. We need to think about the wise use of health care, which means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.”
【小題1】Routine cancer screening for the elderly people makes sense because ______.

A．it is believed to contribute to a long life
B．it is part of their health care package
C．they are more sensitive about the health
D．they are in greater danger of tumor growth
【小題2】How do some researchers now look at routine cancer screening for the elderly?
A．It adds too much to their medical bills.
B．They are doubtful about necessity.
C．It helps increase their life expectancy.
D．They think it does more harm than good.
【小題3】What is the traditional view about women screening for breast cancer?
A．It is a must for adult women.
B．It applies to women over 50.
C．It is intended for young women.
D．It doesn’t apply to women over
【小題4】Why do many doctors advise routine screening for cancer?
A．They want to take advantage of the medical care system.
B．They want to protect themselves against medical disputes.
C．They want data for medical research.
D．They want their patients to suffer less.
【小題5】What does the writer say is the general view about health care?
A．Better care, longer life.
B．Prevention is better than cure.
C．Better early than late.
D．The more, the better.

Why play games? Because they are fun, and a lot more besides. Following the rules…planning your next move...acting as a team member…these are all “game” ideas that you will come across throughout your life.
Think about some of the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating (合作) .
Many children’s games have a practical side. Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones. Which sharpens the hand-eye coordination（協(xié)調(diào)）needed in hunting.
Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.
Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it—some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to give people hope through soccer. He created a foundation(基金會(huì)) to provide poor children with not only soccer balls but also a promising future.
Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life.

Researchers in London and Bristol have found that men are particularly likely to yield to depression if their partners are also depressed.
The finding highlights the importance of paying attention to the partners of depressed mothers, as young children themselves are vulnerable (容易受傷的) to social problems if both parents are depressed.
Researchers in London and at the University of Bristol launched their study to investigate whether family structure affects the likelihood of depression in men around the time their child is born. They looked at men from traditional families, men with children from a previous relationship, men whose partners had children by a former partner, and men who were not living with their partners.
All 7,108 participants filled out a questionnaire on depression, and answered questions about their age, education level and employment status. Details about the quality of their relationships with their partners, networks of friends and previous life events were also recorded.
About 3.5 percent of the men and 13 percent of their partners suffered depression around the time their child was born. While men in stepfamilies or who were not living with their partners were twice as likely to get depressed as those in traditional families, this could be explained by other factors that are more common in nontraditional families, such as poor education and relationship conflicts.
Even allowing for all these factors, however, the partners of women who were suffering from prenatal (圍產(chǎn)期的) depression were significantly more likely to become depressed themselves, the researchers report in an American journal. Ten percent of women who were depressed had depressed partners. For the healthy women, the figure was only 2.6 percent.
Previous research suggests that families with two depressed parents may need special attention. A researcher in Atlanta has found that primary school children with two troubled parents have difficulty relating to their peers. “It’s extremely important to look at the whole family.” she says.
【小題1】What can we conclude from the first two paragraphs of this passage?

A．Men often beat their children.
B．Depressed women often have depressed partners.
C．All young children are vulnerable to social problems.
D．Women with children often have depressed partners.
【小題2】Why did researchers in London and Bristol carry out such an investigation?
A．To see what kind of family environment is ideal for children to grow up in.
B．To study whether family structure affects depression in men when their child is born.
C．To investigate why so many men get depressed when a child is born.
D．To see whether it is true that behind every depressed man there is a depressed woman.
【小題3】What kind of men is least likely to get depressed when their child was born?
A．Men in stepfamilies.
B．Men who were not living with their partners.
C．Men in traditional families.
D．Men in nontraditional families.
【小題4】According to the passage, which of the following statements is NOT true?
A．Ten percent of women who were depressed had depressed partners.
B．2.6 percent of healthy women were depressed.
C．Special attention should be paid to families in which both the father and the mother were depressed.
D．Primary school children whose parents were both depressed couldn’t get along well withtheir peers.

It started off as part of French military training and has since evolved as a sport, founded by Sebastian Foucan and David Belle, to encompass a wide variety of techniques, philosophies and exercises. Park-our now enjoys the devotion of many die-hard fans across the world and has been the source for much inspiration.
But what is park-our? It is the art of using only your body to navigate from Point A to B in the least time possible, which involves besides leaping, climbing and sprinting, various unusual and complex movements to overcome barriers. Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond’s wonderful performances that the sport has become popular worldwide.
Yes, that’s pork-our, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Park-our is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.
Park-our can be just as exciting and charming as it sounds, but its participants see much more in park-our than that.
To overcome all the obstacles on the course and in life is part of the philosophy(理念)behind park-our. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in park-our and never fall back from them in your life to reach the destination successfully. A park-our lover said, “I love park-our, because its philosophy has become my life, my way to do everything.”
Another philosophy we’ve learned from park-our is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself so that you earn energy and confidence.
【小題1】 Park-our has become popular throughout the world because of ________.

A．its founder, David Belle B．the film, Casino Royale
