Question

 (北京市北大附中2007年5月高三最后適應(yīng)測試B篇)

Obesity is becoming one of the biggest threats to children’s health, a recent nationwide investigation has warned, pointing out that students’ physical indicators are declining because of a lack of enough exercise.

The past five years have witnessed fast growth in the number of fat children—in some big cities, the number has even doubled, the survey showed.

In Beijing, for example, latest figures from the local education authorities show that the height, weight and chest measurement of young students keep expanding, while physical indices, such as lung capacity, speed and strength, are going down.

The blood pressure of half the secondary school students is above normal; and the number of obese students has increased by 50 percent compared with five years age.

In the urban areas of Beijing and five other economically more developed regions, the average obesity rate of male students in primary schools has reached 12.9 percent.

Nationwide, the obesity rate of children is 8.1 percent and 3.1 percent in urban and rural areas.

“China has entered the era of obesity,” Beijing-based Workers’ Daily quoted Ji Chengye of the Child and Adolescent Health Section of the China Preventive Medicine Association as saying．“Childhood is the first age group affected by obesity, to which society has not paid enough attention,” Ji said．“Obesity in childhood will influence health for life,” the expert added.

The increase in indoor activities such as watching television, surfing the Internet, playing computer games or doing homework, is one of the main reasons for children’s obesity, according to Ji, because it means lack of exercise and little chance for burning calories．Another reason is consumption of excessive junk food．“In the past, children used to drink water．Now they prefer sweet beverages; and some have totally given up water,” Ji said．He also blamed intensive promotions of sweets and junk food, which make it hard for children to resist the temptation.

Also, because of pressure of competition to enter good higher schools, teachers sacrifice students’ physical exercise time for classes.

For instance, about 60 percent of school masters in Beijing admitted that the one hour of outdoor physical exercises per day is not always followed.

“Problems of obesity will not only influence children’s physical and psychological development but also become a “time bomb for the country’s future economic development and public health system,” said Chen Chunming, head of International Life Sciences Institute Focal Point in China.
