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.

This is a chat between a human “user” and a computer. The computer was designed to be as human as possible. It was taught to talk to humans. It has also learnt from what people have said to it. This has helped it to become even more human.
The technology that makes George talk is called Jabberwacky. This technology recently won the Loebner Prize. The Loebner Prize is a competition to find the most realistic artificial intelligence (人工智能). The judges had to talk to the computer. They typed questions to it. The computer answered.
Jabberwacky’s design team say it will be a long time before the programme is very realistic.
It was first created in 1982. It has been getting better every year since then. Each time it chats to a human, the list of things to say gets bigger. This means the computer has more things to say when you talk to it.
It is hoped that a computer like this will replace humans in call centres. When the programme is more realistic, this will be possible.

D. It takes a long time to make Jabberwacky more realistic.
According to a new survey, students’ safety has become a big problem. For example, nearly 50% of students say they are worried about robbery (抢劫) on the way to and from school. Now in some big cities in China, some schools have been giving students an important course: self-
protection. Students like this course because it is very useful. They can learn how to save lives and how to stop danger before it really happens and does any harm.
Chen Haoyu, a teacher at Beijing No. 25 Middle School, gives young students advice on how to deal with different kinds of dangers.
If you are robbed
Keep calm. If you cannot cry for help or run away, give the robber your money. Try to remember what the robber looks like and tell the police later everything that happened.
If you are in a traffic accident
If a car hits you, you should remember the car number. If it is a bicycle, try to call your parents before you let the rider go. This is because you don’t know how badly you may get hurt. If it is raining hard with much lightning
Don’t stay in high places and stay away from trees.
When there is a fire
Run away as fast as you can. Put wet things on your body and try to find an exit. Don’t take the lift and don’t try to take anything with you.
If someone is drowning
If you can’t swim, don’t get into the water. Shout for help.
