TOKYO, JAPAN--What do you do when you see a cockroach (蟑螂)? Do you hit it with a newspaper? Do you step on it?
When researchers at Tokyo University see a cockroach, they take the remote control and make the cockroach turn around, run left or right, or go forward. These scientists are changing the cockroaches into robots. Each cockroach has a very small pack that has in it a microprocessor(微处理器).Then researchers can send signals from the remote control to the pack. The signals control the movements of the cockroaches.
Why does anyone want to control a cockroach? “Insects can do many things that people can’t,” says Isao Shimoyama, head of robot research at Tokyo University. In a few years, he says, these robot insects will carry very small cameras. They will be able to move through earthquake rubble(瓦砾)to look for people or move under doors to find information about someone.
This may seem strange, but the Japanese government thinks the research is very important. The government is giving the scientists $ 5 million for this research.
First, the researchers breed (培育)hundreds of cockroaches. They use only the American cockroach because it is bigger and stronger than other cockroaches. Then they choose the best cockroaches and remove their wings and antennae(触须). They put small packs where the antennae were. The packs weigh about three grams, or about two times the weight of the cockroaches themselves. “Cockroaches are very strong,” says Ralph Holzer, who is a researcher at Tokyo University. “They can lift 20 times their own weight. ”
With a remote control, the scientists send signals to the packs. When a cockroach gets the signal, it moves. The problem is that the cockroaches don’t always move in the right direction.

A coral island is very nice to look at. It looks like a ring of land with trees, grass, and flowers on it. One part of the ring is open to the water. There is a little round lake inside the island.
If you look into this lake, you will see beautiful coral. You may think they are flowers.
If you look at a piece of coral, you will see many little holes in it. In each of these holes a very small sea animal has lived. These sea animals make the coral.
They began to build under the water. Year after year, the coral grew higher and higher. At last it grew out of the water.
Then the sea brought to it small trees and something else. After some years, these things changed into earth. Sometimes the wind brought seeds to this earth. Sometimes birds flew over it and brought seeds to the island. The little seeds grew. In a few years there were plants all over the island. In a few more years there were trees growing there.

For Zhang Xiaomeng, a senior high school girl from Jiangsu, meeting her best friend Hua Xuan was the best part of her time at junior high school. They went to class together, had lunch together, and even went to the washroom together. Having one or two best friends is important, said Xu Zheng, a teacher from Jiangsu. “Students have secrets. They don’t want to tell their parents,”Xu added. However, being too rebellious (叛逆的) in junior high is the biggest regret for Liu Anqing, a senior high school student from Fujian. “I didn’t listen to my parents. I quarreled with my mother every week,” said Liu. “I wish I could go back to that time and get on well with them.” Time also needs to be taken care of. Zhang Zihua, 15, from Shanxi, thought he had plenty of time to prepare for the big exam at the end of Junior 3. Then one day, he was told: “The exam is in 100 days.” “We need a strong knowledge base to pass the exam. But I didn’t care about it,” said Zhang. Gu Xiaoli, a teacher from Jiangsu, said that it’s never too late to catch up. “No matter your regrets about wasted time, you can always pick things up from now,” said Gu.
