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(机器人). Each cockroach has a very small packet that has in it a microprocessor (微处理器). Then researchers can send signals (信号) from the remote control to the packet. 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 research keeps 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 packets where the antennae were. The packets 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 packets. When a cockroach gets the signal, it moves. The problem is that the cockroaches don’t always move in the right direction.

A. they want cockroaches to do things people can’t in the future

B. they want to control the movements of the cockroaches

C. they want cockroaches to take photos of the earthquakes

D. they want to send signals to the packets on the cockroaches

2.Scientists control cockroaches’ movements _________________________.

A. by removing their wings

B. by sending signals from the remote control

C. by using very small cameras

D. by removing their antennae

3.What can cockroaches do to help people?

A. They can lift 20 times their own weight.

B. They can help people to carry very small cameras.

C. They can keep hundreds of cockroaches.

D. They can search for those people in rubble after an earthquake.

4.What problem do the cockroaches meet with?

A. The cockroaches sometimes don’t move.

B. The cockroaches are too big to move through earthquake rubble.

C. The cockroaches sometimes move in the wrong direction.

D. The cockroaches can only lift 20 times their own weight.

Country music is a kind of modern-day pop music, originated (起源) in the southern United States and Appalachia mountains. The singers usually play the guitar, and in the 1920s they started using electric guitars. Nowadays people use the violin, banjo, and slide-guitar as well.

The music at the very beginning was generally very smooth, beautiful and the phrasing structure (句法结构) also was simple. In the 1950s, American country music was about other things, for example, love and money. In the 1960s, songs were often full of anger, and some of them made fun of the political (政治的) leaders. During the 1990s, American country music became more and more popular. Song writers were no longer writing about the modern values of the USA—money, success or expensive things to buy. Instead they were writing once more about things that were usual for everyone.

Today country music has become a big business. It brings in a lot of money. Now, it has reached all parts of the States, from Los Angeles in the west to New York in the east. It remains much the same as before. One subject is “the good old days”. In “the good old days” people praised each other. They believed that the best things in life were free: sunshine, laughing, walks in the beauty of the country, friends and music.
