Losing weight comes with a lot of health benefits—including making your brain sharper.
Yes, it turns out that overweight may damage cognitive functions (认知功能) such as memory and attention. There have been few studies of overweight and cognitive functioning, possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.
Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.
The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says. There is less research on overweight and cognitive functions because researchers _____.
| A. believe overweight only affects our body |
| B. have focused on ways to sharpen people’s mind |
| C. do not consider overweight a main cause for low cognitive ability |
| D. are clear about the relation between weight and mental functions |
The result of Gunstad’s study shows that ______.
| A. losing weight has little effect on people’s memory |
| B. losing weight can improve people’s mental functions |
| C. overweight people are likely to have psychology problems |
| D. overweight people’s abilities of concentration differ greatly |
What is Gunstad planning to prove next in his research?
| A. Slim people are smarter than overweight people. |
| B. Healthy diet is better than exercise in losing weight. |
| C. Traditional ways of losing weight are better than operation. |
| D. Overweight people will get smarter by taking more exercise. |

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel” (燃料). Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) , like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise forms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.According to the passage,_________.

People in the United States honor their parents with 2 special days: Mother’s Day on the second Sunday in May and Father’s Day on the 3rd Sunday in June. These days are to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two days offer an opportunity to think about the changing roles of mothers and fathers. More mothers now work outside the home and more fathers must help with childcare.
These two special days are celebrated in many different ways. On mother’s Day, people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It’s also a day when people whose parents are dead visit the cemetery (grave). On these days families get together at home as well as in restaurants. They often have outdoor barbecue for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are more valued than those bought in stores. It’s not the value of the gift that is important, but “the thought that counts”. Greeting card stores, florists, candy makers, bakers, phone companies and other stores do lots of business during these holidays.Which is NOT a reason for children to show love and respect for parents?

Every hour spent in watching TV, DVDs and videos as an adult reduces life expectancy by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.
The research claims that a sedentary(久坐的) lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities it offers for unhealthy eating.
The academics conducting the study set out to calculate the overall risk to life expectancy from watching television. Their research involved more than 11,000 people over the age of 25.
Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be associated with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity."
The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.
But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States.
Earlier this year, a separate study suggested the risk of developing type 2 diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box.
England's Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks. We hope these studies will help more people realize that there are many ways to get exercise."We can learn from the passage that_______
| A．whether you watch TV or not has nothing to do with how long you will live |
| B．if an adult watches TV for six hours every day, he will die five years earlier |
| C．physical inactivity and obesity won't shorten your life |
| D．a sedentary lifestyle offers huge benefits. |
The word "it" in the second paragraph refers to
| A．a sedentary lifestyle |
| B．eating |
| C．smoking |
| D．obesity |
What do we know from the last three paragraphs?
| A．People in the United Kingdom watch TV longer than those in the United States. |
| B．That a sedentary lifestyle carries additional risks isn't supported by other studies. |
| C．Watching TV for two hours a day will increase the risk of illnesses or dying early by 20%. |
| D．It is through these studies that we know a sedentary lifestyle carries additional risks. |
The passage is intended to _______.
| A．inform the readers of a research on watching TV |
| B．warn the readers of the harm of watching TV and hope they do sports |
| C．tell the readers watching TV is also a good way to relax |
| D．tell the readers large amounts of people often watch TV |
A woman Vicki once knew a young person named Susan at church. Susan always seemed happy, although Vicki knew she had faced struggles in her life. Her long-awaited marriage had quickly ended in divorce, but her whole face seemed to smile.
One day Vicki asked Susan,“How is it that you are always so happy, you have so much energy, and you never seem to get down?”
With her eyes smiling, Susan said,“I know the secret!”
“What secret is that? What are you talking about?”Vicki asked.
Susan replied,“The secret is this: I have learned there is little I can do in my life that will make me truly happy. I must depend on God to make me happy and meet my needs.

Since I learned that secret, I am happy.”

As the pace（步速） of life continues to increase , we are fast losing the art of relaxation. Once you are in the habit of rushing through lift, being on the go from morning till night, it is hard to slow down. But relaxation is completely necessary for a healthy mind and body.
Stress is an natural part of everyday lift and there is no way to avoid it. In fact , it is not the bad thing it is often supposed 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(忍受) 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 signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises（危机）we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. 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（确定的）links with stress. Since we cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.Which of the following statements is true, according to the passage?
| A．We can find some ways to avoid stress |
| B．Stress is always harmful to people’s health. |
| C．It is easy to change the habit of keeping oneself busy with work. |
| D．Different people can withstand different amounts of stress |
In the last sentence of the passage, “do so” refers to .
| A．“expose ourselves to stress” |
| B．“find ways to deal with stress” |
| C．“remove stress from our lives” |
| D．“establish links between diseases and stress” |
According to the author, the right attitude toward stress is .
| A．to avoid it |
| B．to try to deal with it |
| C．to regard it as a vital motivation |
| D．to find some relaxation |
