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.

Computer games are very popular with many teenagers. The games can be good entertainment (娱乐) in their spare time. Some teachers think it is a good idea to use the same games to teach teenagers in school too.
They think that games can make children work harder. Also, if students are interested in the games, they will learn more. They say students are better at listening and thinking when they enjoy a lesson. They also think that answers are more thoughtful and work is neater when games are used.
Geography has been taught this way in some schools. A game is played by children and maps are drawn of the game “World”. The images help the students “see” the world they are mapping. Some teachers also use games to help students start to write. They talk about people or places in the game. They write stories about what happens in the game “World”.
Other teachers do not think that games are helpful in school. They say students are thinking about the game and not their work. They say the students have an excuse to play. They also think that the game keeps students busy, but they are not always learning.
Teachers have different answers to this question. Computer games are helpful for some teachers. They are unhelpful for others. No research has been done into the effects (影响) on students’ grades. We have to use our own thoughts to decide. Do you think that computer games should be used in your classroom? How helpful would they be?
