Now satellites are helping to forecast(预报）the weather.They are in space,and they can reach any part of the world.The satellites take pictures of the atmosphere （大气），because this is where the weather forms(形成），They send these pictures to the weather stations.So meteorologists(气象学家）can see the weather of any part of the world.From the pictures,the scientists can often say how the weather will change.
Today,nearly five hundred weather stations in sixty countries receive satellite pictures.When they receive new pictures,the meteorologists compare them with the earlier ones.Perhaps they may find that the clouds have changed during the last few hours.This may mean that the weather on the ground may soon change,too.In their next weather forecast,the meteorologists can say this.
So the weather satellites are a great help to the meteorologists.Before satellites were invented,the scientists could forecast the weather for about 24 or 48 hours.Now they can make good forecasts for three or five days.Soon,perhaps,they may be able to forecast the weather for a week or more ahead(提前）。

Every family will have computers and puters will help us know a lot all over the world. Robots will help us do most of the housework. They can help us do some cleaning, cooking or washing. We can do some shopping and see a doctor without going out. Students can study at home on computers. People will live to be 200 years old because of the better medical care.
Our life will be better and better. For this, we should study hard. I believe we’ll be able to do this.
