Recent studies suggest that vegetarianism may be associated with lower cholesterol (胆固醇), 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.

Reports from the World Cancer Research Fund (WCRF) suggest that making simple lifestyle changes could prevent some 40 percent of breast cancers alone in Britain and the United States, as well as tens of thousands of stomach cancers.
“Even in 2011, people are dying unnecessarily from cancers that could be prevented through keeping a healthy weight, diet, physical activity and other lifestyle factors,” said a WCRF medical and scientific adviser.
WCRF findings are supported by World Health Organization (WHO) reports, which say regular exercise can prevent many diseases such as cancers and heart diseases.
Cancer is a leading cause of death around the world and its incidence(发病率) is rising. Each year around 12.7 million people discover they have cancer and 7.6 million people die from some form of the disease. There are about 200 known types of cancer.
Rachel Thompson, the WCRF’s head of science, said that while the message was simple — that not smoking, eating good food and being a healthy weight can help ward off many cancers — it was still a difficult one to get across.
The WHO says adults should do at least 150 minutes of exercise a week. This could be done by walking for 30 minutes five times per week or by cycling to work every day.
Peter Baldini, head of the World Lung Foundation, also called on all governments to introduce smoke-free laws and raise the price of cigarettes. Tobacco kills millions of smokers every year, and tobacco-related lung cancers also kill hundreds of thousands of people who don’t smoke but have been exposed to it second-hand.
“There isn’t a magic bullet to cure all forms of cancer, but we have the opportunity and the duty to protect people from developing cancer wherever possible,” Baldini said.
小题1:Which of the following words can best take the place of the phrase “ward off” in the sixth paragraph?
A.protect | B.prevent | C.develop | D.cure。 |
A.Exercising and eating healthily can help to reduce cancer risk. |
B.Each year about 12.7 million people are diagnosed with cancer around the world. |
C.Every year millions of people die from smoking and lung cancers. |
D.Adults should walk for fifty minutes three times per week. |
A.Simple life changes could stop millions of cancers |
B.Cancer is a leading cause of death |
C.Our bad lifestyle caused many diseases |
D.The incidence of common cancers is rising |
A.advise people to develop healthier lifestyle. |
B.warn people of the danger of cancers |
C.explain why many people die from cancers every year. |
D.introduce the ways to protect people from developing cancers |
A.all the lung cancers are linked to smoking |
B.there is no medicine to cure the cancers but it’s our duty to find one |
C.all governments should take measures to control smokers and protect people’s health |
D.it’s our opportunity and duty to persuade people to give up smoking |
Every year, 390,000 children under age 15 go to hospital emergency rooms with bike-related injuries. Of that number, about one third children suffer head injuries and an estimated 200 die. By wearing a helmet, a child can reduce her risk of injury by as much as 85 percent. But remember —— a bicycle helmet must fit properly to be safe. Here are five steps to making sure your child"s helmet fits properly.
1) If you haven"t bought your child"s helmet already, you might want to consider one with a rear stabilizer(稳定杆). A rear stabilizer holds the back of the head gently and helps the helmet stay correctly positioned.
2) The helmet should fit closely and shouldn"t slide from side to side or front to back. If your child can put two fingers on both temples inside the helmet, it"s too big. Try a smaller size. But if the next size down is too small, use the fit pads(护垫). Fit pads come in different sizes and attach to the helmet with Velcro.
3) Tell your child to open her mouth widely and ask if she can feel the helmet push down onto the top of her head. If she can"t, you need to readjust her helmet.
4) To prevent strap slippage, wind a rubber band around the strap where it meets the fastener.
5) Recheck the fit regularly.
You should replace the bicycle helmet:
If she has been in an accident with it.
If the buckle(金属扣) breaks or if a piece breaks off.
If it doesn"t have a U.S. Consumer Product Safety Commission, American Society for Testing and Materials, or Snell Memorial Foundation sticker.
If it doesn"t fit correctly. Even if the helmet fit perfectly two years ago, it might be too small now.
小题1:Who is this passage mainly written for?
A.Children. | B.Teachers. | C.Parents. | D.helmet producers. |
A.The bike-related injury is a serious threat to the children. |
B.The bicycle helmets must fit properly while the children are biking. |
C.It’s necessary for the children to wear helmets while biking. |
D.Many students suffer bike-related injuries every year. |
A.She must buy a smaller size. |
B.She can use some fit pads. |
C.She can put fingers on both temples inside the helmet. |
D.She must make helmet slide from side to side. |
A.buy a new bicycle helmet for her |
B.mend the bicycle helmet himself |
C.continue to use the bicycle helmet |
D.throw away the broken buckle |
The cheerful Mr. Pickwick, the hero of the novel by Charles Dickens, is seen in illustrations as someone who is plump and happy. In 18th century paintings, beauty is equated (使…等同) with rounded bodies and soft curves. But nowadays being overweight is seen as indicating neither a cheerful character nor beauty but an increased risk of heart disease, stroke and diabetes.
So what do you do? Diet? Not according to England"s chief medical officer, Sir Liam Donaldson. He says that physical activity is the key for reducing the risks of obesity, cancer and heart disease. And the Health Secretary John Reid even said that being inactive is as serious a risk factor in heart disease as smoking.
So, having bought some cross trainers, how much exercise should you do? According to Sir Liam Donaldson, at least 30 minutes of moderate activity five days a week. Is going to the gym the answer? Luckily for those who think that running machines are boring, the Health Development Agency believes that physical activity that fits into people"s lives may be more effective. They suggest taking the stairs rather than the lift, walking up escalators, playing active games with your children, dancing or gardening. And according to a sports psychologist, Professor Biddle, gyms "are not making the nation fit", and may even cause harm.
There"s new scientific evidence that too much exercise may actually be bad for you. Scientists at the University of Ulster have found that unsuitable exercise releases dangerous free radicals that can adversely (oppositely) affect normal function in unfit people. The only people who should push their bodies to that level of exercise on a regular basis are trained athletes.
So, should we forget about gyms and follow some expert"s advice to reduce sedentary (久坐不动的) activities and increase exercise in our daily life? After all, getting off the bus a stop early and walking the rest of the way can"t do any harm! One final thought. How come past generations lacked gym facilities but were leaner and fitter than people today?

A.people who help you do exercise | B.places where you can do exercise |
C.a kind of shoes | D.a form of vehicles |
A.an increased risk of diseases | B.a happier life |
C.a cheerful character | D.a beauty |
A.how to keep fit and avoid fatness. | B.increased risks for overweight people. |

First, the researchers mixed some of these cells with antigens found in the amino acid(氨基酸). Antigens help the body react to infection. Then the scientists added some bacteria. Within twenty-four hours, the cells produced a lot of interferon, a substance that fights infection. Cells not mixed with the antigens did not produce interferon.
In the second part of the study, eleven people drank five to six cups of black tea every day. Ten other people drank the same amount of instant coffee. That is dried coffee mixed with hot water.
Two weeks later, and again two weeks after that, the researchers tested the blood of all twenty-one people. They also looked at what happened when they added bacteria to the blood cells. They found that the tea drinkers produced five times more interferon after they started drinking tea. The coffee drinkers did not produce interferon.
Doctor Jack Bukowski led the study. He says the antigens added to the gamma delta T cells were responsible for the increased reaction to the bacteria. He says that the study also showed that the cells were able to remember the bacteria and fight them again the next time.
Earlier research already has found that tea can help prevent heart disease and cancer. Doctor Bukowski says the new study must be repeated by more people. “If the findings prove to be true,” he says, “then tea drinking might also help protect against bacterial infections.” He says the amino acid L-theanine could be removed from the tea and used as a drug to strengthen the body’s defenses.

A.L-theanine | B.Gamma delta T cells |
C.interferon | D.bacteria |
A.to add some bacteria to the blood cells |
B.the body to produce more gamma delta T cells |
C.the body to produce more interferon |
D.to mix antigens with some of the cells in the body |
A.the findings of the study have already proved to be true |
B.further study is needed to prove the findings true |
C.he has taken some amino acid L-theanine from tea and made a drug with it |
D.he is not sure whether tea help prevent heart disease and cancer |
A.Tea Is Better than Coffee | B.Our Body Needs Tea |
