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

Dear editor,
My English teacher is very strict with us. Several days ago, when we were in class, Tom asked me a question. But my English teacher thought we were speaking in class. She asked us to stand at the back of the classroom for a few minutes. This made me unfair. After that, I feel nervous in her class, so I don’t like her class. However, I really want to learn English well. What should I do?
Yours,
Mike
Dear Mike,
I am sorry you are having difficulty with your English class. Every teacher wants his or her students to study hard. So I think you should have a talk with your English teacher and tell her what you were doing with Tom that day. If she knows your worries, maybe she will help you with your English. And she will be pleased to hear you want to learn English well. Of course, you should know that what your teacher did was good for you. When you are not trying as hard as you can, she has to stop it and try to help you. Wish you have a better life!
Yours,
Editor

Anger is a kind of feeling. Many things can make you angry. When your teacher gives you too much homework, when your team loses an important game, when a friend borrows your favorite thing and then breaks it, you may get really angry.
Usually, your body will tell you when you are angry. For example, you breathe faster, your face turns red, and you may want to break something or hit(打) someone, but sometimes, you hide(隐藏) your anger. For example, you may hide it in your heart. The problem is that if you do this, you may get a headache or your stomach may hurt.
In fact, it’s not good to hide your anger, and it’s normal for you to get angry sometimes. But anger must be let out in the right way, without hurting others or yourself.
When you get angry, you can talk about it with other people. It’s helpful to talk about your anger with an adult, such as parents, a teacher, etc. When you talk about anger, those bad feelings can start to go away. Here are some other things you can do when you start to feel angry: talk to a good friend; count from 1 to 100; give someone a hug(拥抱); go for a bike ride; think about good things, etc.
Remember that how you act when you are angry can make everything better or worse. Don’t let your anger control you.
