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.

举一反三
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?
小题1:Mr.Pickwick and the paintings of the 18m century are used as examples to show that_____.
| A．beauty should be overweight |
| B．a fat man is usually a cheerful character |

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.
小题1:We may know from the text that ______ can be found in different kinds of tea.
| 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 |
| C．Tea Can Help Prevent Cancer | D．Tea May Help Fight Infection |
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(体力的) 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.
小题1:Healthy people may die from heart disease of ____________.
| A．too much job stress | B．working too hard | C．feeling valued | D．being satisfied |
| 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. |
| A．increased | B．reduced | C．raised | D．cured |
| A．advise people not to work long hours |
| B．suggest that everyone be satisfied with everything |
| C．ask us to learn to enjoy ourselves |
| D．tell us that job stress threatens our health nowadays. |
But what teenagers like to eat is not necessarily what they should be eating. According to the National Diet and Nutrition Survey, far too many young people in the UK between the ages of four and 18 consume too much fat, sugar and salt in their diet and take in too many calories. Meanwhile their intake of starchy carbohydrates (淀粉类碳水化合物), fibre, iron, vitamins and calcium is too low.
For a growing body, eating foods containing plenty of calcium, such as milk, yoghurt and cheese, is particularly important as calcium is essential for the development of healthy, strong bones. Similarly, foods that are rich in iron are good for young, rapidly developing bodies, so red meat, bread, green vegetables, dried fruit and fortified (强化的) breakfast cereals (谷类食物) are also recommended.
It is during our teenage years that lifestyle habits can become entrenched (根深蒂固的), so it is important that young people are educated about what foods are good for them. In 2005, in an attempt to change eating habits and open teenagers’ minds to new flavors and new tastes, celebrity chef Jamie Oliver launched a ‘Feed Me Better’ campaign. As part of a television series, ‘Jamie’s School Dinners’, he worked with teachers and cooks in a number of schools across the UK to provide more healthy, nutritious school meal options. Although the campaign was rather resisted at the beginning, it was generally regarded as a huge success and helped to influence governmental policy on nutritional standards for school meals.
No one expects to end the teenage love affair with fast and junk food but, hopefully, if projects like ‘Feed Me Better’ and the Government"s own ‘Change4Life’ campaign continue to give out the right messages, more young people will understand the importance of balancing occasional treats with healthier food options.
小题1:What can we conclude from the first two paragraphs?
| A．British teenagers eat too much junk food. |
| B．British teenagers need to take in more calcium. |
| C．What British teenagers like to eat is probably what their bodies need |
| D．British teenagers should reduce their intake of starchy carbohydrates. |
| A．to improve their brainpower |
| B．to build healthy strong bodies |
| C．to provide energy for their body |
| D．to help change their eating habits |
| A．show off his excellent cooking skills |
| B．teach students how to cook nutritious meals |
| C．make the public keep an eye on school food |
| D．improve the children’s diet at school |
| A．Teenagers should never eat any junk food at all. |
| B．It’s easy for children to give up unhealthy eating. |
| C．It’s okay for a healthy eater to have a little junk food. |
| D．Once developed, our eating habit will never change. |
In a large study of 9,000 people, doctors discovered that those who drank one or more sodas a day had a 30% increased risk for obesity(肥胖), a 25% increase in the risk for abnormal(非正常的) blood sugar levels, and a 32% increase in the odds of having low levels of good cholesterol(胆固醇).
All of these factors increase the risk for heart disease. And there was no difference in the results for those who drank diet soda over regular soda. It’s something that surprised even the researchers.
Critics of the study say diet soda may not be the cause of increased risk of heart disease. Connie Diekman is president of the American Dietetic Association. "It does not conclusively say that this will cause that."
In other words, it could be that unhealthy people like soda. Dr. Vasan found those who drink soda generally tend to have greater caloric intake. They eat more saturated fat and trans fats. They also eat less fiber and exercise less. Diet soda drinkers may also share this unhealthy lifestyle. Dr. Vasan agrees that the link he found between heart disease risk and diet soda needs additional study.
小题1: What does the underlined word “innocuous” in the first paragraph probably mean?
| A．popular. | B．harmless. | C．effective. | D．risky. |
| A．Only people who overdrink sodas have high risk for heart disease. |
| B．In the study, about one quarter of people have high blood level. |
| C．Both regular and diet sodas can probably increase the risk for heart disease. |
| D．Dr. Vasan is the leader of the American Heart Association. |
| A．All the experts agree with the results of the study. |
| B．Sodas of any kind are certain to increase the risk for heart disease. |
| C．People have expected the results of the research. |
| D．More studies are needed to prove the results. |
| A．By comparing opinions. | B．By giving advice. |
| C．By showing facts. | D．By discussing information. |
