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.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 |
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. |
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 |
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. |

Years ago I worked at a factory in a small county.Every day I got up very early and often did much extra work at night.I was so tired and exhausted.My whole life was hopeless.Then one day I read the following article from a magazine:
"A woman went to live with her husband in camp on the Mojave Desert(沙漠)during the war.She simply hated the place:the heat was almost unbearable,125 degree in the shade,the wind blew incessantly,and there was sand-sand everywhere.Finally,in desperation(不顾一切地)she wrote her parents in Ohio that she couldn't stand it another minute and was coming home.
Quickly came the reply by airmail from her father-just two lines:
'Two men looked out from prison bars.One saw the mud,and the other saw stars.'
The daughter did some real thinking,not only with the intellect(思维)but also with her heart.She decided to stick to her post.
She made friends with the natives,learned to love the country,and eventually wrote a book about it.
The desert hadn't changed,but her attitude had.Because she listened with her heart to the words her father sent,a whole new world opened up to her."
A change of attitude could change everything.
After reading the article,I was deep in thought(陷入沉思)…

The underlined word"unbearable"means________in Chinese.

After she received her father's reply,the woman________.

In the morning,we went camping along a path in Green Natural Park.We were happy because it was a sunny day.We were expecting an enjoyable two-day holiday.On the way,we kept singing and making jokes.
