Scientists will put some robot fish into the sea near Spain this year. These robot fish will help people find out the pollution in the water. If the robot fish are able to finish their work successfully, the team of scientists hopes the fish will be used in rivers, lakes and seas around the world.

The robot fish are about 1.5 meters long. There is a detector(探测器) in their bodies. It can find the pollution in the water, and then the robot fish will eat part of it.

They can “swim” for eight hours in the sea freely and send back information to people on the beach. After their energy runs down, they will go back to the beach by themselves.

There are five robot fish altogether. Each costs about 29,000 dollars. They are part of a three-year project between engineering company BMT Group and Essex University in southeastern England.

Hi! My name is Mark. I live in a town in the west of Shanghai. Over the past twenty years, great changes have taken place here.

In the past, my hometown was only a small village. There were no tall buildings. But now more and more tall buildings appear and the roads get broader. My father used to work in a small post office. We contacted each other mainly by sending letters. Now we can get in touch by using telephones, mobile phone, the Internet and so on. The world becomes smaller and smaller.

We can find our life more comfortable. We live in big flats. We can enjoy milk, vegetables, fruit and meat for meals. We can also enjoy wonderful films, and listen to music with MP5. In the past, we couldn’t enjoy life like this.

On the other hand, pollution has become a serious problem in our daily life. In the past, there were not many factories. So the water was clean and the air was fresh. However, the water and the air aren’t clean any more, because too many factories have polluted them. The government has taken action to reduce the pollution. Now things have been better.

I am sure my hometown will be more and more beautiful.
