Can plant 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(捕蝇草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of the book.. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly(苍蝇) touches one of the hairs, the leaf closes very quickly. Then the fly can't go out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly. Why do plants do it? 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 the 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.

Can you imagine a world without the Internet? It's surprising to think about it. Now, China has more than 162 million Internet users, according to the China Internet Network Information Centre. This is the second largest number of users in the world after the United States. Today, 66% of Chinese "netizens(网民)" are teenagers. "They spend about thirteen hours every week online," said Qian Hulin, an Internet expert. Doctor Song in Beijing Xuanwu Hospital said about 14% of Chinese netizens who are teens often went on playing online games for over ten hours.
The main reasons why teenagers surf the web are to search for information, to communicate with others and to have fun. On the Internet, teenagers can find out almost anything. And surfing the web can help students with their homework and widen their knowledge.
Li Dong, a teacher at No. 41 Middle School in Shijiazhuang, is for her students using the Internet. "When we talk in class, students who surf the Net usually know more background information than the others," she said.
In addition, people can use the Internet to write letters or stories and send emails. Many teens keep in touch with their friends online. It is cheaper than phoning somebody far away and also much quicker.

Many animals hide to stay alive. They hide in many ways. Some animals hide in leaves; some animals hide in snow. Usually their colors or shapes help protect them. It's hard to see an Arctic bear in snow. Its white fur helps protect it. Chameleons(变色龙) can hide by changing colors. Their skin turns the same color as what is around them. Some chameleons can change colors in five minutes.

Many animals try to look bigger than they are to stay alive. Some animals can make other animals think they are very big. If they look very big, animals that are looking for food will run away. Bears can walk on two legs. They look very, very scary. Some animals will run away from them.

Many animals try to stay around other animals. This helps them stay alive. Zebras stay close together so that they can help each other look out of danger. Seeing many stripes at once can also confuse animals that want to eat them. Some birds stay in a circle, each toward a different direction. In this way they can also help each other stay alive by looking around for animals that many want to eat one of them.

North American black bears are shy animals. They are fearful by nature, and will usually run away if they see or hear people. Because of this, it can be difficult for scientists to learn about these animals.

In order to study black bears, researchers from New Jersey, the US, catch bears and use drugs to help them go to sleep. Researchers then work out the size and the weight of the bears, take blood, to test for diseases, remove a tooth and take it to the lab to find out its age. From these studies, researchers want to find out how many bears live in New Jersey, how long they live, and how many babies they produce.

But in Minnesota, the US, researchers study bears that are completely awake. The bears know the researchers' voices and they are not afraid of the research team. With the help of a few grapes to keep the bears busy, researchers can touch them to check their hearts, look at their teeth, and do other jobs. Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives."

In both places, the main purpose is the same—to make sure there is a healthy population of black bears. But the research methods and the kinds of information that researchers are able to collect are quite different.

Sitting too much is now listed with smoking and junk food as a bad habit that increases your risk of heart disease.

New Australian research shows that half-an-hour in the gym will not make up for the waist-expanding damage caused by spending the rest of the day sitting.

But the good news is that doing chores(家务杂事) in the house or gently walking around the office while on the phone might be enough to keep you fit.

The study joins the growing body of evidence suggesting too much sitting might undo the benefits of exercise.

The study measured the intensity(强度)of physical activities in 168 subjects over seven days. If found that, regardless of how much exercise they did or their total sitting time, those who took more breaks from sitting had lower risk of thick waists and lower levels of blood lipids(脂质).

“Higher levels of blood lipids have been linked to a heightened risk of heart disease,”principal researcher Genevieve Healy of the University of Queensland said. "What the study shows is that there are benefits in just getting up regularly and interrupting your sitting time."

Researchers behind the Stand up Australia project have written to the Rudd Government requesting $ 3.5 million for a two year study into how long sitting affects the health and productivity of workers.

The latest study builds on work that is shifting the health promotion focus from purposeful exercise, such as running, to lower intensity activities throughout the day.

The Australian research bas been backed up US studies, which show standing up is enough to double the metabolic(新陈代谢) rate and the amount of calories burnt.

“To hold a body that weighs 77kilograms upright take a .fair amount of energy from muscles", said professor Marc Hamilton from the University of Missouri. "There is a large amount of energy associated with standing every day that cannot be easily replaced by, 30 to 60minutes in the gym."
