The population of the Earth is growing faster. It is important that we look after the Earth. We need it!

The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.

In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can't get food from many of the things that we “give” the Earth. Animals and plants can't eat metal, plastic and glass. These things will stay in the ground for many, many years.

Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals (化学制品) in the water, the plankton(浮游生物) can die. If there isn't any plankton, many animals have nothing to eat.

So what can we do? Don't leave any rubbish in the countryside! Don't make so much rubbish!

In common with many countries, Britain has serious environmental problems. In 1952, more than 4,000 people died in London because of the smog. The government introduced new laws to stop smog from coal fires and factories and the situation improved a lot.

Today, London is much cleaner but there is a new problem: smog from cars. In December 1991, there was very little wind in London and pollution increased a lot. As a result, about 160 people died from pollution in just four days.

Part of the problem is the new “out of town” shopping centers. In the past, people often walked to shops near their home or went by bus. Now, many people drive to the new shopping centers. As a result, the small shops have disappeared and more people have to travel to do their shopping.

Critics (评论员)say that Britain needs better and cheaper public transport. Transport in Britain is very expensive. An early morning train trip from Glasgow to London (about 600 km) can cost about 100 pounds, for example. A short 15-minute bus trip can cost over 1.00 pound.

Many people are trying to reduce the use of cars in Britain. Some cities now have special bicycle paths and many people cycle to work. Some people also travel to work together in one car to reduce the pollution and the cost.

PowerPoint Presentations(PPT)are taking the place of writing on the blackboard with chalk. Someday, will robots take the place of human teachers?

In Japan, a robot is going to enter classrooms to help teachers. Last week the Japanese company Honda Motor Co. showed the public its robot at a Tokyo museum. The robot's name is Asimo. Students will see Asimo in science classes and learn the wonders of science.

Asimo is 130 centimeters tall with a round head. It can jog, walk up stairs and wave. It can also avoid things on its way and have simple talks with you. Asimo is an experienced worker for humans. It has worked as a guide in showrooms. But this will be the first time it works as a teaching assistant in classrooms and in formal teaching!

How will Asimo help in class?A teacher explained the way Asimo worked to students in last week's show. Asimo has sensors(感应器)inside its body to keep its balance.

The smart Asimo tilted(倾斜)its body when it stood on a shaking platform(平台). Asimo kept its balance. But a wooden person beside Asimo fell(See the above picture).

When you walk, you pass your weight from the heel to the toe. The Japanese teacher explained this with Asimo at the museum. He moved the robot in slow move. Asimo made learning science more interesting for students!

Asimo will soon help teach thousands of primary students and junior high schools in two Japanese cities. Hopefully, robot teachers will arrive in our classrooms in China one day.
