So meteorologists(气象专家)can e 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(比较)them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours .This may mean 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 3 or 5 days. Soon, perhaps , they may forecast the weather for a week or more ahead(提前)小题1:Satellites travel__________.A．in spaceB．in the atmosphere C．above the groundD．above space小题2:Why do we u the weather satellites to take pictures of the atmosphere?
