In China，more and more middle school students are getting shorter sleeping time than be-fore． Most students sleep less than nine hours every night，because they have much homework to do. Some homework is given by their teachers，and some by their parents． Also，some students don't know how to save time .They are not careful enough while they do their homework，so it takes them a Iot of time． Some students spend too much time watching TV or playing computer games．They stay up very late． Some students have to get up early every morning on weekdays to get to school on time by bus or by bike．lt can be a long way from home to school．

Schools and parents should cut down some of the homework so that our children can enjoy more than nine hours of sleep every night for their health． For children，we should make best use of our time． When we have enough time for sleeping，we will find it much better for both our study and health．

Most people think of lions as strictly African beasts, but only because they've been killed off almost everywhere else. Ten thousand years ago lions spanned vast sections of the globe, and so did people, who —as they multiplied and organized —pat pressure on competitors at the top of the food chain. Now lions hold only a small fraction of their former habitat, and Asiatic lions, a subspecies that split from African lions perhaps 100,000 years ago, hang on to an almost impossibly small slice of their former domain.

India is the proud steward of these 300 or so lions, which live primarily in a 560-square-mile (1,450-square-kilometer) sanctuary. It took me a year and a half to get a permit to explore the entire Gir Forest —and no time at all to see why these lions became symbols of royalty and greatness. A tiger will slink through the forest unseen, but a lion stands its ground, curious and unafraid —lionhearted. Though they told me in subtle ways when I got too close, Gir's lions allowed me unique glimpses into their lives during my three months in the forest. It's odd to think that they are threatened by extinction; Gir has as many lions as it can hold —too many, in fact. With territory in short supply, lions prowl the periphery of the forest and even leave it altogether, often clashing with people. That's one reason India is creating a second sanctuary. There are other pressing reasons: outbreaks of disease or natural disasters. In 1994 canine distemper killed more than a third of Africa's Serengeti lions —thousand animals —a fate that could easily befall Gir's cats. These lions, saved by a prince at the turn of the 20th century, are especially vulnerable to disease because they descend from as few as a dozen individuals. "If you do a DNA fingerprint, Asiatic lions actually look like identical twins," says Stephen O'Brien, a geneticist who has studied them. Yet the perils are hidden, and you wouldn't suspect them by watching these lords of the forest. The lions exude vitality, and no small measure of charm.

Though the gentle intimacy of play vanishes when it's time to eat, meals in Git are not necessarily frenzied affairs. For a mother and cub sharing a deer, or a young male relishing an antelope, there's no need to fight for a cut of the kill. Prey animals are generally smaller in Gir than they are in Africa, and hunting groups tend to be smaller as well. The lions themselves aren't as big as African lions, and they have shorter manes and a long fold of skin on their undersides that many lions in Africa don't have.

We have met the enemy, and he is ours. We bought him at a pet shop. When monkey-pox, a disease usually found in the African rain forest, suddenly turns up in children in the American Midwest, it’s hard not to wonder if the disease that comes from foreign animals is homing in on human beings. “Most of the infections (感染) we think of as human infections started in other animals,” says Stephen Morse, director of the Center for Public Health Preparedness at Columbia University.

It’s not just that we’re going to where the animals are; we’re also bringing them closer to us. Popular foreign pets have brought a whole new disease to this country. A strange illness killed Isaksen’s pets, and she now thinks that keeping foreign pets is a bad idea. “I don’t think it’s fair to have them as pets when we have such a limited knowledge of them,” says Isaksen.

“Laws allowing these animals to be brought in from deep forest areas without stricter control need changing,” says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected animals may infect their owners. We know very little about these new diseases. A new bug (病毒) may be kind at first. But it may develop into something harmful (有害的). Monkey-pox doesn’t look a major infectious disease. But it is not impossible to pass the disease from person to person.
