Are you a TV lover?Can you imagine living without TV?Well, you could give it a try．

　　A group of Americans, TV-Turnoff Network, have an idea．From April 19 to 25, they are asking children all over the world to turn off their TVs for one week．They hope children will find more interesting things to do．Maybe they can read some books, or learn to swim, or paint a picture．Since 1995, about 24 million people in the US have taken part in TV-Turnoff Network days, watching TV too much can bring big problems to schools, health and families．They want kids to watch less TV．What do you think?

Bad for your studies

　　American scientists did a study of 1,300 children．They watched the children for 4 years．They say that if children watch too much TV, they don’t do well in school．

Bad for your health

　　Studies show that when children watch too much TV, they eat more unhealthy food．More children are getting overweight．Overweight children become ill more easily．Watching TV too much is also bad for their eyes．

Bad for family life

　　About 40％ of American families watch TV at dinner time．That means that they don’t talk very much when they eat together．

Also, too many violent things

　　An American study says that before a child turns 18 years old, he or she will see 200,000 violent things on TV．Some kids become violent in real life．

　　In the Caucasus Mountains, nearly 50 out of every 100,000 people live to celebrate their 100^th birthday, and many don’t stop at 100!In American only 3 people in 100,000 reach 100．But these old people aren’t alone．The people who live high in the Himalaya Mountains and the Andes Mountains, seem to share the secret of long life, too．

　　First of all, hard physical work is a way of life for all of these long-lived people．They begin their long days of physical work as children and never seem to stop．For example, Mr．Rustam is 142 years of age．He has experienced several wars．His wife is 116 years old．They have been married for 90 years．Mr．Rustam doesn’t want to stop his work as a farmer．“Why? What else would I do?” He asks．Oh, he has slowed down a bit．Now he might work for 6 hours in the field instead of 10．

　　Another factor(因素)that may contribute(有助于)to the good health of these people is their isolation．Most of them are kept off the modern world．

　　Inherited(遗传的)factors also help．Most of the longest-lived people had parents and grandparents who also reached very old ages．So good families genes(基因)may be one factor in living longer．

　　Finally, although these three groups don’t eat exactly the same food, they eat little animal meat．Their diets are full of fresh fruits, vegetables, nuts, grains, cheese and milk．They never eat more food than their bodies need．

Time to lose weight

　　Zhou Xiang, at Shijiazhuang No．4 Middle School, Hebei, is 1.73 metres tall, but weighs 80 kilograms．The 14-year-old Junior 3 boy is the biggest in his class．

　　He always felt good when people called him‘Hercules(大力士)’．But he doesn't feel so good about being big any more．

　　Why is that? Because of a new rule for Junior 3 students taking the High School Entrance Examination in late June．

　　There will be a fitness test on May 9．On the new test, students who are too heavy or too light only get one point out of two．

　　Tian Jingbo at the Shijiazhuang Education Bureau(教育局)said he hopes this will make students stronger and healthier．‘It can make students eat healthily and exercise more,’Tian said．

　　Zhou is too heavy．The education bureau says his weight should be from 61.6 to 69.9 kilograms．

　　Zhou is afraid his weight could be a big problem．‘If I lose one point, I probably will miss the best high school,’he said．

　　To get two points on the test, Zhou decided to lose 10 kilograms in two months．For the first few days, he only had a piece of bread and some milk for breakfast．

　　He exercises more, but that only makes him want to eat more．He said he was hungry all the time．‘When I finish the exam, I'm going to eat a horse,’he said．

　　Zhou's class has seven other students either too fat or too thin for the test．Others have the right weight now but worry that their weight will change in two months．

　　Almost all of them have scales(秤)at home to see what they weigh．

　　At Shijiazhuang Children's Hospital, Li Hongling, a doctor, said about 60 or 70 per cent would get the two points．

　　She did a study of 2,880 middle school students in 2002 and found that 16 per cent were overweight．

　　Li said the only good way to lose weight is to live a healthy life：eat less food, watch less TV and play more sports．

　　‘Losing weight too quickly could be bad for your health,’Li said．
