TOKYO, JAPAN－What do you do when you see a cockroach(蜂螂)? 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' always move in the right direction．

　　Long, long ago, a donkey(驴)fell in a dry well．The animal cried for hours as the farmer tried to think out what to do．Finally, the farmer thought the animal was too old and the well needed to be covered up anyway, so he decided not to try to save the donkey．

　　The farmer invited his neighbors to 　　1　　 him．They began to shovel(铲)dirt into the well．The donkey cried harder．Then a few shovelfuls later, he quieted down．The farmer looked 　　2　　 the well, and was surprised by what he saw．

　　While every shovelful of dirt hit his 　　3　　, the donkey would shake(抖)it off and take a step up on the new layer(层)of dirt．　　4　　 the farmer's neighbors continued to shovel dirt on top of the animal, the donkey would shake it off and take another step up．

　　Soon the donkey stepped up out of the well and ran away, to the 　　5　　 of all the neighbors．

　　The 　　6　　 we get from this story is that if life shovels some dirt on us, we must get out of the well and not let it cover us．We must learn to shake it off and take a step up．Each of our 　　7　　 is a stepping-sone(石头)．We can get out of the deepest well by never 　　8　　!
