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.

Animals are more like us than we ever imagined．They feel pain, they experience stress, they show affection, excitement and love．All these findings have been made by scientists in recent years---and such results are beginning to change how we view animals.
Strangely enough, some of this research was sponsored by fast food companies like McDonald’s and KFC．Pressured by animal rights groups , these companies felt they had to fund scientists researching the emotional and mental states of animals.
McDonald’s, for instance, funded studies on pig behavior at Purdue University, Indiana．This research found that pigs seek affection and easily become depressed if left alone or prevented from playing with each other．If they become depressed, they soon become physically ill．Because of this, and other similar studies, the European Union has banned the use of isolating pig stalls from 2010．In Germany, the government is encouraging pig farmers to gibe each pig 20 seconds of human contact a day, and to provide them with toys to prevent them from fighting
Other scientists have shown that animals think and behave like humans．Koko, the 300-pound gorilla at the Gorilla Foundation in Northern California, for instance, has been taught sigh language．Koko can now understand several thousand English words, more than many humans who speak English as a second language．On human IQ tests, she scores between 70 and 95.
Before such experiments, humans thought language skills were absent from the animal kingdom．Other myths are also being overturned, like the belief that animals lack
self-awareness．Studies have also shown that animals mourn their dead, and that they play for pleasure.
These striking similarities between animal and human behavior have led some to ask a question: “If you believe in evolution, how can’t you believe that animals have feelings that human beings have?”
Until recently, scientists believed that animals behaved by instinct and that what appeared to be learned behavior was merely genetically-programmed activity．But as Koko the Gorilla shows, this is not the case．In fact, learning is passed from parent to offspring far more often than not in the animal kingdom.
So what implications does this knowledge have for humans? Because of this, should we ban hunting and animal testing? Should we close zoos? Such questions are being raised by many academics and politicians．Harvard and 25 other American law schools have introduced courses on animal rights．Germany meanwhile, recently guaranteed animal rights in its constitution---the first country to do so.
68．McDonald’s and KFC give money to support scientist to do research on animals,because_____
A．they are international big companies.
B．they love animals.
C．they are pressured by animal right groups.
D．they earn a large amount of money and want to do some good deeds.
69．The research on pigs at Purdue University shows that______
A．pigs love being alone.
B．pigs easily become physically ill.
C．pigs need affection.
D．pigs don’t like to play with each other.
70．Which of the following statements is NOT true?
A．Animals behave by instinct.
B．Animals have self-awareness.
C．Animals have feelings and love.
D．Animals do not have language skills.
71．Should we ban hunting and animal testing?

B．No
C．Not certain
D．Not mentioned
