Good Housekeeping has discovered that even if a child wear a helmet when she bikes, or skates, it may not protect her from a serious head injury.
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.

The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health. There are plenty of “energy drinks” on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!
But after a careful check you may find that most energy drinks have lots of caffeine(咖啡碱)in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much. Caffeine makes your heart beat fast. Because of this, the International Olympic Committee(IOC) has limited(限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

New research suggests that speaking more than one language may delay different kinds of dementia(痴呆), that is the loss of mental ability. In fact, researchers say, speaking two languages appears to be more important than the level of education in defending against dementias.
A study in India examined the effect of knowing more than one language in delaying the first signs of several dementias. Researchers studied nearly 650 people whose average age was 66. 240 of those studied suffered from Alzheimer's, the most common form of mental decline(下降). 391 of the subjects spoke two or more languages. Researchers found the dementias began about four-and-a-half years later in those who spoke two languages compared to those who spoke only one language. The level of education had no effect on the age at the first sign of dementia.
Thomas Bak, from the Center of Cognitive Aging at the University of Edinburgh in Scotland, who helped to organize the study, suggests that individuals who speak more than one language train their brains by moving back and forth between different words and expressions. He also believes this effort improves what scientists called executive(执行的) functioning, which often weakens in people with dementias. He states that researchers found there was no extra gain in speaking more than two languages.
Mr Bak says it does not appear important whether you learn another language at a young age or later in life. It's not something that “you missed the boat when you do not do it as a baby.” It is something that is still quite useful and powerful when you do it as an adult.
【小题1】The finding of the study is that________.
| A．learning more than one language can cure dementias |
| B．speaking two languages may delay kinds of dementias |
| C．the level of education matters in defending against dementias |
| D．people who suffer from dementias will lose mental ability |
| A．people who were studied in the study |
| B．notices that were put on about the study |
| C．questions that were asked in the study |
| D．methods that were used in the study |
| A．the more languages one speaks, the less chance of getting dementias |
| B．people’s executive functioning often strengthens with age |
| C．when you learn one more language makes no difference |
| D．it is much easier to learn one more language at a young age |
| A．a research plan | B．a health magazine |
| C．a book review | D．a business magazine |

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity（肥胖）. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract（消化道）, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens（过敏原） and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize（中和）the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
【小题1】 It can be inferred from Para. 2 that __________.
| A．foods with natural enzymes help people keep fit |
| B．we’d better be cautious about raw and whole foods |
| C．it is essential for people to protect their vital organs |
| D．giving up cooked and refined foods is a new lifestyle |
| A．destroy body’s cells | B．may lead to obesity |
| C．are difficult to digest | D．stop body’s metabolism |
| A．To warn people of the problem of obesity. |
| B．To advocate eating more raw and whole foods. |
| C．To inform people of the harm of processed foods. |
| D．To tell the differences between raw and processed foods. |
| A．Different causes of acid accumulation. |

| C．Suitable types of raw and whole foods. |

“Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour (跑酷).
Do you love running? It is a good exercise, yet many people find it boring. But what about making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? 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 parkour, 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. Parkour 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.
Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.
Overcoming all the obstacles on the course and in life is part of the philosophy behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life, to reach the destination successfully. A parkour lover said, "I love parkour because its philosophy has become my life, my way to do everything."
Another philosophy we've learnt from parkour 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 that you earn energy and confidence.
【小题1】Parkour has become popular throughout the world because of________.
| A．its founder, David Belle | B．the film, Casino Royale |
| C．its risks and tricks | D．the varieties of participants |
| A．streets | B．objects | C．barriers | D．roofs |
| A．It challenges human abilities. | B．It is a good but boring sport. |
| C．It needs special training. | D．It is a team sport.. |
| A．reach the destination as soon as possible |
| B．choose the easiest way |
| C．challenge extremes |
| D．consider safety first |

Smaller than your fist, your healthy heart just goes on and on. It will beat more than 60 times a minute for 70 years or more. That’s something that most of us take for granted. But it’s an amazing fact.
60 times a minute for 60 minutes is 3,600 times. What physical thing can most of us do 3,600 times in one hour? Blink? Maybe. Tap our fingers on the desk? No. Jump up and down? Certainly not! But our heart keeps beating, hour after hour. Every day, it pumps almost 2,000 gallons of blood through our blood vessels(血管). It takes you about five years to drink 2,000 gallons of water.
And, unlike your knees or your back, your heart does all this work without ever complaining（抱怨）! You never know that it’s even there. Your heart is such a reliable “silent partner” that people forget to care for it. For many, the first indication（迹象）that their heart isn’t working properly is a serious heart illness! Over 650,000 Americans die of some kind of heart disease every year. Cancer kills 560,000, stroke kills 143,000, and accidents kill 118,000 Americans annually.
Like accidental deaths, many heart disease-related deaths can be avoided if people simply follow the advice of the experts. Unfortunately, most people seem to listen to a little voice in their head that says, “It won’t happen to me. ” So these people keep on smoking and drinking. They continue to eat too much meat. And their only “exercise” is getting off the sofa to get something out of the fridge. Please follow the following steps to keep your heart healthy.
【小题1】The text is most probably taken from a (an) __________.
| A．art book | B．science fiction |

The World Health Organization (WHO) planned to study the relationship between the eating habits of the people and the disease. Two doctors were chosen to make the study. They flew to Africa south of the Sahara and during the next two months visited ten countries. They found that serious diseases of poor eating, often mistaken for other diseases, existed in all parts of Africa. The diseases were similar and could therefore all be named kwashiorkor. The diseased children are usually from one to four years old. As the illness progresses, the child’s stomach becomes swollen by liquid collecting in the body. The skin changes color and may break out in open sores（疼痛）. The hair changes color and starts to fall out. The patient loses all interest in his surroundings and even in food, and becomes so weak that he wants to lie down all the time. Stomach liquids are no longer produced.
The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat. Their mothers, after stopping their breastfeeding, gave them foods full of starches（淀粉）instead of greatly needed proteins. They found that the addition of milk to the food of the children suffering from kwashiorkor saved many lives.
The unbelievable thing about kwashiorkor is that the very existence of the disease—which has been killing thousands of children for centuries—was not even recognized in Latin America as recently as ten years ago. The deaths of those children were mistakenly listed as due to other diseases. It was the WHO’s work in Africa that led to the discovery of the problem in Central America.
【小题1】From the passage we learn that kwashiorkor is a disease caused by __________ .
| A．poor living conditions | B．lack of proteins in food |
| C．breastfeeding | D．lack of food |
| A．it has no symptoms at all |
| B．it is hard to identify signs of it |
| C．it doesn’t last long enough for careful observation |
| D．it is hardly different from other diseases |
| A．Taking a special medicine. |
| B．Avoiding any food containing starch. |
| C．Having more meat or milk. |
| D．Taking medicine full of proteins. |
| A．Milk and Meat Are Daily Necessities |
| B．Kwashiorkor and Improper Eating Habits |
| C．A New Form of Illness in Africa and Latin America |
