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(微處理器）.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(瓦礫）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(觸須）. 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.

1.The scientists are changing the cockroaches into robots because ______.

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 packs on the cockroaches

2.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 breed hundreds of cockroaches.

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

3.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

4.What problem do the rcscarchcrs meet with?

A．The cockroachcs sometimes clon;t move.

B．The cockroachcs sometimes move in ihc wrong direction.

C．The cockroachcs arc too big to move through earthquake rubble.

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

 

Germs(細(xì)菌) are everywhere. You can’t see them, but they are on your desk, on your computer, and even in the air!

Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.

Warmer Weather Brings Germs

The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes(蚊子), carry dangerous germs. These germs cause headaches(頭疼), fever, and can even kill people.

Under Your Skin

Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too, they enter(進(jìn)入) your body when you touch your eyes, nose, or mouse.

Fighting Germs

Your immune system(免疫系統(tǒng)) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(細(xì)胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs.

What can you do to fight germs? You should wash your hands with soap(肥皂) and water. Soap kills many germs, and water washes them away.

1.According to the text, insects ___________.

A．kill germs	B．carry germs
C．protect germs	D．love germs

2.The underlined word “there” refers to _______.

A．cooler countries	B．hot countries
C．everywhere	D．the world

3.What do antibodies do?   

A．They kill germs and wash them away.

B．They find and develop germs.

C．They help protect us from germs.

D．They carry dangerous germs.

4.Which can be the best title for this text?  

A．Germs Are Everywhere

B．Weather Is Changing

C．Skin Stops Germs

D．Germs Are Developed
