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 scientists hope the fish will be used in rivers, lakes and seas around the world.

The robot fish are about 1.5 metres long. There will be a detector (探测器) in each fish’s

body. It can find the pollution in the water, and then the robot fish will eat part of it.

Unlike other robots, the robot fish don’t need to be operated (操作) by people far away. The robots all have a big battery (电池) that can last for about eight hours. They can “swim” in the sea freely and send back information to people on the beach. After their batteries run 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 by the joint effort of the engineering company BMT Group and University of Essex in England.

Many people like to travel by plane, but I don’t like it because an airport is usually far from the city. You have to get there early and wait for hours for the plane to take off and it is often late. you can’t open the window. You can’t choose the food. Planes are fast, but they still take hours to get out of the airport and into the city.

I like traveling by train. I think trains are safe. Railway stations are usually in cities. When you are late for a train you can catch another one .you can walk around in the train and open the windows. You can see many interesting things on your way. I know it takes a little more time.

I also like cars. You can start your journey when you want to, and you don’t need to get to a railway station or a bus stop. Also you can carry many things with you in a car. But sometimes there are too many cars on the road.
