Micro blogs like Weibo are nothing new for the young Chinese. A newspaper in Chengdu did a survey last month. It found that 90 percent of junior high school students use micro blogs.

They give students an outlet (出口) for emotion. “I use micro blogs to record my life. I let everyone ‘see’ my feelings and complaints,” said Liu Fangyue, 14, from Xiamen No.1 Middle School. They have fun with classmates even after school. “I would send a message to praise someone who came first in the exam,” said Liu.

Teachers also join in the fun. “When I sit down to talk to my students, they may not tell me their real thoughts,” said Lu Dongping at Nanning No. 2 Middle School. “But on micro blogs, they are more relaxed. They even make fun of me.”

You would be wrong if you think micro blogs are all about fun. Zhong Yun from Xiamen Haicang Experimental School sees it as a tool to learn English. The 13-year-old girl follows foreign stars such as Avril Lavigne and Justin Bieber.

“In order to understand their English posts, I have to check the dictionary and learn many new words,” said Zhong.

“Micro blogs widen students’ perspectives (观点), but there are rules to follow,” said Shi Zhongying, a professor from Beijing Normal University. He shares some of them with micro bloggers.

“Manage your time, and don’t let micro-blogging affect your studies and health,” said Shi. “Don’t give out your name, family address or phone number on micro blogs. You should also respect truth and other people’s privacy (隐私).”

We see many animals every day, but we would be worried if we saw any of these animals on our way to school!

Walking sharks

In 2006, scientists found a new kind of shark off the coast of Indonesia. It can “walk” with its fins along the coral reefs. These walking sharks are about 1 to 1. 2 metres long. They eat shrimp, crabs and small fish. If they are surprised by something, they can swim away using their fins.

The platypus

The platypus is found along the rivers and lakes of eastern Australia. It lays eggs like a bird, has webbed feet like a frog, a bill like a duck and is as poisonous as a snake! We are pleased to hear that it spends much of its life underground.

An unusual dolphin

In 2006, a Japanese fisherman caught an unusual dolphin. It has an extra set of fins near its tail, about the size of human hands. Scientists say that its extra fins could be the remains of back legs. This may be proof that dolphins once lived on land. Evidence from fossils tells us that dolphins were once four-footed land animals. Scientists believe that as they spent more and mor time in the water, their back legs slowly disappeared.
