The Internet has become part of teenage life. There’s a report on 3,375 students aged from 10 to 18 in seven Chinese cities. It says that 38% of them believe they use the Internet often. While most of them get useful information and use the Internet to help in their studies, some are not using it in a good way. Many are playing online games too much. A few even visit Web sites they should not look at. Bad things can happen if young people spend too much time on the Internet.

    In order to help young people use the Internet in a good way, a textbook on good Internet behavior has started to be used in some Shanghai middle schools this term. It uses real examples to teach students all about good ways of using the Internet. Some students also make online friends. But if you are meeting a friend offline, let your parents know.

    Teachers and parents all think the book is a very good idea. It will teach students how to be a good person in the online world. It will be a guide for teens using the Internet and keep students away from bad sites.

Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big. And they can eat small animals. One famous meat-eating plant is the Venus flytrap.

The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly(蚊子) touches one of the hairs, the leaf close quickly. The fly cannot get out. In about half an hour, the leaf presses(挤压) the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.

How can that happen? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all these important things, especially nitrogen(氮). Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let’s hope that some of the bigger plants don’t get the same idea!

When Christie Andrews was born, she weighed less that half of one kilogram. Her heart was the size of a large coin. Her mother said Christie was so small that she could hold her in the palm of one hand.
Christie couldn’t breathe without a machine to give her oxygen. If she had been born 20 years earlier, she would probably have died at once. She needed two operations, but she survived without serious damage.
Twenty years ago , 90% of all premature(早产) babies died. Today, doctors manage to save four out of every five, because they have better machines for breathing and better ways to feed the babies.
But saving Christie’s life cost more than $ 400,000. In some cases, doctors spend 1 million dollars saving a single child. The parents usually don’t have enough money to pay. The government, an insurance company or the hospital picks up the bill. Even after a baby goes home from the hospital, it may require medical care.
Some people think it makes more sense to spend money saving 10 adults who have cancer or other diseases than saving one small baby. But nobody wants to be the doctor who has to tell parents to their faces, “Sorry, I won’t save your new child.”
