Last Sunday afternoon, I was having dinner in a restaurant when my friend Poor came in. Poor is working in a bank and is quite rich, but he is always borrowing money from his friends and never pays it back. Poor saw me and came to sit at my table. He had never borrowed any money from me. When he was eating, I asked him to lend me two dollars. To my surprise, he gave me the money at once.“I have never borrowed any money from you,”Poor said,“So you can pay for my dinner.”

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.

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

2.What can cockroaches do to help people?

3.Scientists control cockroaches’ movements ______.

4.What problem do the rcscarchcrs meet with?

The English language is different from any  36  language. Yet English words do not  37  the same. It is always  38 . People need new words  39  new inventions and new ideas. Different words come into use or older words are used  40 a new way.
English can 41 by borrowing words from other languages. The word “tomato” was borrowed from Mexico, the word “coffee” came from Turkey, and “tea” from  42  and so on. Now new space and science words  43  from other countries, too. New words are also made by adding two words  44 . The words “strawberry”, “postman” and “blackboard” are made up of two parts.
Sometimes, new words are  45  forms of old words. The word “photo” was made from “photograph” by cutting off the  46  of the long word. The word “plane” was made by cutting off the  47  part of “airplane”. 48 “smog” was made by using only the first two letters of “smoke” and cutting off the front part of “fog”. And products can become new words. Our “sandwich” was named after  49  named Sandwich, and “jelly(果冻)” was a name made up by the company that  50 made this product.

You probably know you should say “please” and “thank you” at restaurants. You probably know the rules of a library. You know you should respect and be nice to your classmates. But do you have music manners?
Keep It Down! You have to notice the volume of your music. You should not play your music so loud that everyone around you can hear it. Some people might even get angry. Usually, when you play the music loud on an MP3 player, other people can’t hear the words of the song. They just hear a loud sound. No one wants to listen to this. Very loud music can also be bad for your ears. So even if you are alone when listening to our MP3 players, you shouldn’t turn it up too high.
Take Them Off! You need to know when to turn your MP3 off and put it away. Libraries, and schools don’t allow MP3 players. There are other places, like museums, that don’t have rules, but it would be rude to have your MP3 player on. Sometimes, it doesn’t make sense to listen on your MP3 player at event. Why would you listen to music at a play, a movie or a sporting event? You would miss what is going on and others would wonder why you even came.
Take One Out! Once in a while it’s okay just to take out one earphone and not other. Imagine you are listening on your MP3 player when someone asks you the way. It would not be rude to take out one earphone, tell him the way, and put back the earphone and continue listening. You can also do this when you order food at a fast-food restaurant or when you answer the telephone and it’s not for you.
It’s Your Choice! There are times when you need to decide what is best. For example, some people can listen to music on their MP3 players when reading books, while others think it is disturbing. In cases like this, you need to do what seems right for you.
