In many countries today, laws protect wildlife. In India, the need for such protection was realized centuries ago.
About 300 BC, an Indian writer described forests that were somewhat like national parks today. The killing of beasts was carefully supervised(监视). Some animals were fully protected. Within the forest, nobody was allowed to cut timber(wood for building), burn wood for charcoal (木炭), or catch animals for their furs. Animals that became dangerous to human visitors were caught or killed outside the park so that other animals would not become uneasy.
The need for wildlife protection is greater now than ever before. About a thousand species of animals are in danger of extinction, and the rate at which they are being destroyed has increased. With mammals(哺乳动物), for instance, the rate of extinction was about one species(种类) every fifty years from AD 1 to 1800, but now it is about one species every year. Everywhere, people are trying to solve the problem of protecting wildlife, caring for the rapid growth of the world's population.
4. The example of man's connection with wildlife protection can date back to________.
A. the third century
B. more than 2000 years ago
C. AD 1 to 1800
D. over 300 years ago
5. The underlined word"extinction" probably means ________.
A. being hungry B. being killed
C. growing slowly D. dying out
4. B。由第二段第一句可知,人类保护野生动物的活动可追溯到公元前300年,至今已2300多年。 5. D。 由该句前后的in danger of和the rate at which they are being destroyed has increased可知,extinction意为"绝种"。
Researchers found that compared with teens who spent much of their free time in front of TV sets, those who were physically active often had higher self-respect, better grades and were less likely to have risky behavior like taking drugs, smoking, or drinking．The findings, based on a national survey of nearly 12,000 middle and high school students, were published in a journal．
"Across the board, children who engaged in any kind of activity were belier off than kids who watched a lot of TV," said study co author professor Penny Gordon Larsen of the University of North Carolina．
Other studies have linked certain content of television programs, such as violence and sex, to children's behavior．But beyond this issue, Gordon-Larsen said that kids who spend hours watching TV "miss opportunities" to develop skills, learn teamwork and have other experiences that their more active peers benefit from．
That doesn't mean, however, that kids have to be on the football team． The study found that some activities like skating and skateboarding——which adults sometimes frown upon——were also related to better self respect and less risk taking．
That skaters were better behaved than TV watchers might come as a surprise to some adults who consider these teens to be bad, according to Gordon-Larsen．Skateboarding is forbidden in many public areas, and some communities oppose building skating parks．But if kids who like to skate have nowhere to do it, "it's a shame," said Gordon-Larsen．
Not only should parents encourage their kids to engage iii the physical activities they enjoy, she said, but schools and communities should also do more to create opportunities for children to be active．
