TOKYO, JAPAN-- What do you do when you see a cockroach? 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 a microprocessor in it. Then researchers can send signals 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 to look for people or move under door 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 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. 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.

D.They can breed hundreds of cockroaches.
3.Scientists control cockroaches movements ________.
A.by removing their wings B.by using very small cameras
C.by removing their antennae D.by sending signals from the remote control
4.What problem do the researchers meet with?
A.The cockroaches sometimes don't move.
B.The cockroaches sometimes move in the wrong direction.
C.The cockroaches are too big to move through earthquake rubble.
D.The cockroaches often lift 20 times their own weight.
5.What's the object of this article?
A.The cockroaches B.The signals
C.The cockroach robot D.The researchers
An 11-year-old blind girl is proud of walking alone every day to and from school. Why? She has to walk past so many barriers (障碍物) in her way. The girl's home is near the school, yet her mother follows her without letting her know.
The case of the girl shows the barrier-free(障碍物) facilities (设施) are not enough in her city. Many other cities are short of barrier-free facilities as well. There's no well-designed path for the blind. In fact. in the early 2000s, some cities started to build barrier-free facilities for disabled people. However, almost 20 years later, only a few large cities have had facilities of high quality.
It's common that sidewalks are taken up with barriers. Few workers are sent to move them away, so it's dangerous for the blind to walk on them. Also, some other barrier-free facilities are badly destroyed（毁坏）. Only a few workers are assigned (分配) to do the task of repairing the broken ones.
Some ideas can make a difference — build more barrier-free facilities, employ(雇用) more of workers and require money. In a word, more money is needed to carry on with the work. It’s our duty to make life easy for disabled people, so that they can live without barriers some day.
