Now satellites(卫星) 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, because this is where the weather forms. They send these pictures to the weather stations. So meteorologists(气象学家) can see the weather of any part of the world.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with 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 meteorologists 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.
(
A. Because clouds form there.
B. Because the weather forms there.
C. Because the weather satellites can do it easily.
D. Because people like to collect these pictures.
(
A. without studying satellite pictures
B. before they receive satellite pictures
C. as soon as they receive satellite pictures
D. after they have compared the new satellite pictures with the earlier ones
(
A. For one day.
B. For two days.
C. For five days.
D. For seven days or even longer.

A. Satellites are used in taking pictures of the earth.
B. Satellites are used in receiving pictures of the atmosphere.
C. Satellites are used in forecasting the weather.
D. Satellites are used in doing many kinds of work.
