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

The biggest safety threat（威胁）facing airlines today may not be a man with a gun ,but the man with portable（便携式）computer in business class .In the past 15 years ,pilots have reported about over 100 incidents that could have been caused by electro-magnetic interference(电磁干扰) .The source of this interference remain unclear ,but increasingly ,experts are pointing the blame at portable electronic devices（设备）such as portable computers ,radio and mobile telephones .
RTCA ,an organization which advises the aviation industry ,has suggested that all airlines ban, such devices from being used during “key” stages of flight ,particularly take-off and landing .Some experts have gone further ,calling for a total ban during all flights .Nowadays ,rules on using these devices are left up to airlines. And although some airlines ban passengers from using such equipment during take-off and landing ,most are not willing to exercise a total ban ,if many passengers want to work during flights .
The difficulty is understanding how electromagnetic fields might affect an aircraft’s computers .Experts know that portable devices give off radiation which affects those wave lengths which aircraft uses for communication .But because they have not been able to reproduce these effects in a laboratory ,they have no way of knowing whether the interference might be dangerous or not .
The fact that aircraft may be in trouble because of the interference raises the danger
that some people may use radio systems in order to damage navigation（导航）equipment .As worrying ,though ,is the passenger who can’t hear the instruction to turn off his radio because the music is too loud .
【小题1】.
.What is said about over 100 aircraft incidents in the past 15 years ?
A They may have taken place during take-off and landing .
B They have been caused by the damage to the radio systems .

D They were caused by the passengers’ portable computers .
【小题2】.
. Few airlines want to refuse a total ban on their passengers because ____ .
A they have other effective safety measures to fall back on
B they don’t believe there is such a danger as radio interference
C the effect of electromagnetic interference is yet to be proved
D most passengers refuse to take a plane which bans the use of radio
【小题3】.
. Why is it difficult to see the effects of electromagnetic fields on computers ?
A Experts lack proper equipment to such research .
B It is dangerous to carry out such research on an airplane .
C It remains a question what wave lengths are to be interfered with .
D Scientists are not able to produce the same effects in laboratory .

A hasn’t formed his own opinion on this problem
B has fully understood the danger of electromagnetic interference
C regards it is as unreasonable to exercise a total ban during flight
D is in favor of banning passengers’ use of electronic devices

FOR many young people, having to attend school with a parent would be their worst nightmare. However, Senior 1 student Li Qinmei is happy taking her father with her as long as she can go to classes. He is disabled and unable to take care of himself.

The 16-year-old country girl in Zhucheng, Shandong Province has experienced one disaster after another in her short life. Li lost her mother at three. Four years later, her father became paralyzed after a tractor accident. At 12, her misfortune returned with the death of her grandma. Since then she has been forced to shoulder all the responsibility for her broken family.

Li learnt to cook and managed to live a life with an allowance of only 24 yuan per month. The most difficult thing she had to deal with was helping her father bathe, dress and use the toilet as he could hardly move.

"I felt embarrassed, and so did my dad. It was really hard at the beginning," she recalled.

During most of her junior school years, Li went to classes only once a month as her father was seriously ill at the time. "I taught myself at home and asked teachers for help on my school days," she explained. Li's hard work paid off this fall. She was admitted by Zhucheng No 1 High School, a local key school, based on her good performance in the entrance exams. The school offered Li and her father a room on campus to live in so she could look after him during breaks.

Once in a while, Li felt sad when she saw her classmates going shopping or hanging out with friends. "I envy them sometimes because they have both mum and dad to look after them. However, I soon feel relieved as I still have my dear dad with me," she said.

Li admitted that the difficulties in life had taught her to be strong. "I believe I will go on and continue my studies at a good university," she said, in a confident tone.

Her teacher Mr. Wang has the same belief. Li made great progress in the recent monthly exams. "She works hard and is always eager to excel (好强的). It's not easy for her never to be late for school, but she has managed to make it work," Wang said.

Parkour is a sport with the aim of moving from one point to another as smoothly, efficiently and quickly as possible using chiefly the abilities of the human body. It’s more similar to martial arts (武术) than to a sport. Parkour focuses on how any obstacle is dealt with, whether the obstacle is either physical or mental.

Inspiration for parkour came from the “Natural Method of Physical Culture” developed by Georges Hebert in the early twentieth century. French soldiers in Vietnam were inspired by Heber’s work and created what is now known as parcours du combatant (障碍训练课程). David Belle, who was introduced to this method by his father Raymond Belle, a Vietnamese soldier who had practiced it, had taken part in activities such as martial arts and gymnastics, and sought to apply his athletic skill in a manner that would have practical use in life.

After moving to Lisses, David Belle continued his journey with others. “From then on we developed,” says Sebastien Foucan, who helped to spread parkour, “and really the whole town was there for us; there for parkour.”

Over the years as devoted practitioners (实践者) improved their skills, their moves continued to grow in scale, so that building-to-building jumps and drops of over a storey(楼层) became common in media description, causing much misunderstanding on the nature of parkour.”

Although many practitioners say parkour isn’t an extreme sport, it does carry risk with it. The practice of running, jumping, and leaping from a variety of urban structures (roof tops, staircases, raised surfaces, walls, etc.) and landing on concrete, of course, carries the potential for injury. Some of the most common injuries include sprained (扭伤的) ankles and injuries to the knees.

According to one practitioner, “One of the biggest differences between parkour and other so-called ‘extreme’ sports is that it is not concerned only with physical skills, but also with one’s mental and spiritual pleasure.”

A. Belle’s devotion to parkour B. the origin of parkour
