Compared to adults, children seem to be moving constantly. So it's no surprise that most parents who are quizzed about their child's physical activity level describe their children as fairly active. But a new study of nearly 2000 British school children suggests that many parents overestimate the amount of physical activity their children are really getting.

The researchers equipped 1892 British school children, ages 9 and 10, with accelerometers that measure all physical  activity  during  a  given  time  period.  The research，known as the Speedy study collected the exercise data from children at  92  schools  in  Norfolk，England, between April and July 2007.

A child was regarded inactive if he or she recorded less than an hour a day of physical activity. Although the majority of children studied were getting enough physical activity, a_sizable_minority_of_children_were_not. Overall,39 percent of girls and 18 percent of boys studied were getting less than an hour of physical activity each day.

But if you asked the parents of the inactive children to describe their child's activity level，the vast majority—80 percent—described their children as fairly or very physically active, according to the findings published in the American Journal of Preventive Medicine. Interestingly, the children themselves had more awareness about their lack of physical activity. Overall, 40 percent of children overestimated their physical activity.

But it wasn't the parents of overweight children who were most likely to guess wrong about physical activity levels. The parents who were most out of touch about their child's physical fitness were more likely to  have children who were slim. Parents of girls were also more  likely  to  overestimate  physical  activity.  The  researchers noted that parents should be educated about the importance of physical activity for children even if the child is not overweight.

“Parents of slim children appear to assume that  their children are adequately active.”the study authors  reported. “Increasing awareness regarding health benefits of physical activity beyond weight control might  help have a correct idea of physical activity levels and encourage behavior change.”

60．According to the Speedy study，what kind of children   can be judged physically inactive?

A. Slim children.

B. Children with less than an hour a day of physical activity.

C. Overweight children.

D. Children out of touch with their parents for a long time.

61．What does the writer probably mean by saying “a sizable minority of children were not”in Paragraph 3?

A. The amount of children's physical activity is far from the writer's satisfaction.

B. Only a small number of children were not getting enough physical activity.

C. A small number of children didn't overestimate their physical activity.

D. The minority of children were not studied at all.

62．The passage is intended to________.

A. encourage parents to fairly judge their children's physical activity levels

B. persuade parents to keep an eye on their children's weight

C. urge children to wear accelerometers during exercise

D. advise parents to keep in touch with their children

Compared to people with bad attitudes，people who are cheerful and relaxed are less likely to suffer from colds，according to a new study.“It’s possible that being upbeat helps the body fight illnesses，” says Sheldon Cohen，the study’s lead researcher from Carnegie Mellon University (CMU) in Pittsburgh.
In a previous（先前的） study，Cohen and his colleagues put cold­causing viruses into the noses of 334 healthy adults. People who tended to be cheerful and lively were least likely to develop sniffles，coughs，and other cold symptoms. People who showed positive feelings were also less likely to mention symptoms to their doctors，even when medical tests detected those symptoms.
Those findings were interesting，but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead，it was still possible that a person’s underlying personality is what matters. Evidence suggests，for instance，that certain people are naturally more likely to be outgoing and optimistic，with high self­esteem and a sense of control over life. This would mean that who we are，not how we feel，ultimately decides our chances of catching colds.
To figure out which mattered more (personality or emotions)，the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. At the end of the interviewing period，people got nose drops that contained either cold or flu viruses. Then，each person stayed in an isolated room for 5 or 6 days. The results showed that everyone in the study was equally likely to get infected. Their symptoms，however，differed depending on the types of emotions that they had reported over the previous 2 weeks. Among those who reported good moods and had been infected with the flu virus，for example,28 percent developed coughs and stuffy noses. On the other hand，those symptoms struck 41 percent of people who had been less upbeat.

What would be the best title for the passage?

Compared to the whole development of history, your life could be like a candle which is lit and then blown out immediately. In other words, life is short —very short. Missing any of the joys life offers is terrible.
So don’t let fears conquer your short and valuable life. If your life is being controlled by your fears, you are most certainly cheating yourself. Courage is the mental (精神上的) muscle that conquers fear. Like all muscles, the more you use it, the stronger it will become. Courage is not something you are born with. That is to say, it must be developed. It has been said that if you face the thing you fear bravely, your fear will leave you.
For years I believed that courageous people had no fear. I was wrong. Eddie Richen Bacher put it very well when he said, "There is no courage without fear." We all have fears; however, not everyone gives in to their fears easily.
There is, very likely, something you have wanted to do for years —move to another city, start your own business, apply for a better position, or go wherever you like. Whatever it is, you should do it. Remember, life is not a practice run. This is it. A little courage leads to more.
Observe those poor people who have no courage. They only tiptoe (蹑手蹑脚地走) through life, hoping they can make it safely to death. You and I never meant to live that way. Learn to live the way you like by no longer living as you dislike. Make good use of your day and have courage. That’s life!
64. We can learn from the passage that courage _______.
A. can be developed quickly                 B. needs to be used more often
C. is formed when one is born                D. makes one very excited
65. What new opinion did the author develop?
A. All courageous people have fears.           B. Those who are brave have no fear.
C. There is no fear without courage.           D. A brave person can live a safe life.
66. What would be the best title for the passage?
A. A Person’s Life Is Short                   B. Don’t Fear Anything
C. Never Give Up Easily                    D. Courage Conquers Fear

Compared to the other parts of the body, our ears don’t ask for much. They don't need to be brushed once a day like your teeth. But they need some special care, especially if you like listening to music with earphones.
Maybe your mum or dad has told you, "Turn that down before you go deaf!" Well, they are quite right. Loud noise might cause hearing loss for a short time or even forever. Think that earphones are a good way to escape from your parents’ eyes? Well. It may not be as good a way as you expect. American doctors have studied a group of 44,000 people who used earphones more than 15 hours per week. The doctors found that 37,000 of them were getting hearing problems.
If you use earphones for too long a time, your ears might feel painful. You could also lose your hearing for the rest of your life.
So don’t wear your earphones too long. Use them less than one hour a day.
Want sharp hearing? Don’t forget to do the following:
Try to stay away from places where there is too much noise, like a disco. If you have to go, wear earplugs.
When swimming, remember to put earplugs into your ears to stop water from getting in.
Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out.
Keep these things in mind! Then you won't be saying "WHAT???" when you are older.
