Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States.
The result: 10% fewer heart attacks, 8% fewer strokes, 4% fewer deaths, 11% fewer new cases of heart disease, and 240 billion dollars in health care savings.
Researchers found it could prevent 100,000 heart attacks and 92,000 deaths every year.
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California, San Francisco was the lead author. She says people would not even notice a difference in taste with three grams, or one half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodium(鈉), which is how foods may list their salt content.
The government says the average American man ears ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also rise. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government interference.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children’s Research Institute show that the calorie information on the menu can influence what parents order for their children.

We humans love to scare ourselves. Newspapers and TV news are full of shock-horror stories about the killer flu virus(流感病毒)but are there things we can do to cut our risk of catching it?
Every year, people in Britain catch the flu virus and some of those who are already ill, or are very young, may die. It is very sad, but modern treatment means that many deaths can be avoided.
Experts tell us that the world is another flu epidemic(流行)and that the latest bird-flu virus would be the most likely cause. Humans can catch the disease only after closely contacting with a sick bird. However, if someone who had normal flu was to come into contact with bird flu, this could be very dangerous. The bird flu virus could attach(附在)itself to the human flu virus, mutate and then start to spread from person to person.
Coughs and sneezes(打噴嚏)always have spread diseases, especially colds and flu, and they still do. If bird flu does begin to infect humans, it will spread through coughs and sneezes.
If you want to stay free of flu and someone coughs or sneezes at you, what should you do?
First, keep your hands away from your face and wash them and your face as soon as you can. If a cough or a sneeze spray misses your face and you accidentally touch a droplet with your hands and then touch your face, the flu or cold bug could creep into your system.

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.

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.

People believe that climbing can do good to health. Where can you learn the skill of climbing then? If you think that you have to go to the mountains to learn how to climb, you’re wrong. Many Americans are learning to climb in city gyms(體育館). Here, people are learning on special climbing walls. The climbing wall goes straight up and has small holding places for hands and feet.
How do people climb the wall? To climb, you need special shoes and a harness(保護(hù)帶) around your chest to hold you. There are ropes(繩索)tied to your harness. The ropes hold you in place so that you don’t fall. A beginner’s wall is usually about 15 feet high, and you climb straight up. There are small pieces of metal that stick out for you to stand on and hold on to. Sometimes it’s easy to see the new piece of metal. Sometimes, it’s not. The most difficult is to control your fear. It’s normal for humans to be afraid of falling, so it’s difficult not to feel fear. But when you move away from the wall, the harness and the ropes hold you, and you begin to feel safe. You move slowly until you reach the top.
Climbing attracts people because it’s good exercise for almost everyone. You use your whole body, especially your arms and legs. This sport gives your body a complete workout. When you climb, both your mind and your body can become stronger.

People who cannot tell all colors apart are said to be color-blind. Most color-blind people can see yellows and blues, but confuse reds with green. It is very rare for a person to be blind to all colors, but they may see everything in shades of black, white and gray.
It is interesting to point out that many color-blind people don’t even realize that they are color-blind, they don’t know that the colors they are seeing and naming are not the actual colors that people with normal vision can see. This can be dangerous when a color-blind person confuses the red and green of a traffic light.

Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long- term stay in cold conditions or exciting part of the body's nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team's findings appear in the journal Cell Metabolism, said, "I'm still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socializing, he added, "It's not just a sedentary(久坐的) lifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said,"Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.
【小題1】What information can we get from the first two paragraphs?

A.Brown fat stores calories and makes us fatter
B.It doesn't take long to turn white fat into brown.
C.Social excitement helps gain more weight
D.Brown fat can burn energy to produce heat.
【小題2】Which of the following statement does the text support?
A.Levels of brown fat can be increased by socializing.
B.The mice lacking social life lose more weight.
C.The research findings haven't been published so far.
D.Dr Matthew During wasn't convinced of the result.
【小題3】We can conclude from the text that _______.
A.the fat in mice's belly was reduced because of the relaxing environment
B.a(chǎn) sedentary lifestyle and high calories foods influence people's social life
C.surfing the Internet may influence people's face-to-face communication
D.cancer and death are mainly caused for lack of social life
【小題4】What’s the main idea of the text?
A.Brown fat is beneficial to people's health.
B.Socializing is unnecessarily important in people's daily life.
C.White fat can be changed into brown fat.
D.Socializing contributes to people's losing weight.

Women consistently lie on social networking sites such as Facebook or Twitter to make their lives appear more exciting, a survey has found.
Researchers found that at least one in four women exaggerated(夸大) or distorted(扭曲) what they are doing on social media once a month. The survey of 2000 women found they mostly pretended to be out on the town, when in fact they are home alone, and polished an exotic(異國(guó)的) holiday or their job.
The most common reasons for women to write “fibs” included worrying their lives would seem “boring”, envy at seeing other people’s more exciting posts and wanting to impress their friends and acquaintances.
Psychologists suggested that as people attempt to “stay connected” on social media, they can in fact “paradoxically(自相矛盾地)” be left “more isolated”. They also said that “the more we try to make our lives seem perfect, the less perfect we feel”.
According to the OnePoll survey, one third of women surveyed admitted to “dishonesty” on social media sites such as Facebook and Twitter at some stage.
Almost one in four admitted to lying or exaggerating about key aspects of their life online between one and three times a month while almost one in 10 said they lied more than once a week.
Nearly 30 percent of women lied about “doing something when I am home alone”, almost a quarter overstated their alcohol consumption while one in five were not truthful about their holiday activities or their jobs. Almost one in five women even lied about their “relationship status”.
“We work very hard presenting ourselves to the world online, pretending and attempting to be happy all the time which is exhausting and eventually unfulfilling,” said Dr Michael Sinclair, a leading British consultant psychologist.
“Leaving out the less desirable imperfections of our lives from the conversations with our `friends` online leads to less opportunity to feel empathized with(與…產(chǎn)生共鳴), resulting in a greater sense of disconnection from others.”
The survey was conducted by Pencourage, a new anonymous (匿名的)“diary-style” social media website.
【小題1】 Which of the words below is closest in meaning to the underlined word “fibs” in Para 3?

A.life experiences B.short stories
C.careful thoughts D.insignificant lies
【小題2】 A woman tends to tell a lie online when she__________.
A.hopes to make more friends
B.envies other people’s exciting life
C.feels lonely at home
D.gets tired of the boring life
【小題3】 A woman might pretend to be happier online than she actually is by __________.
A.a(chǎn)voiding conversations with friends
B.describing her holiday activities
C.leaving out the imperfections in life
D.overstating her trouble at work
【小題4】 According to Dr Michael Sinclair, constantly lying online may __________.
A.eventually make one’s life more exciting
B.a(chǎn)ctually lead to a sense of isolation
C.really improve one’s sense of happiness
D.scarcely have any influence on relationships
