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 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).

There are about 7 billion people on the Earth now. The world’s population is a big problem because it will

cause lots of problems in the future. More people will need more food and will need more room to live in as well.

The world’s population growth rate rose from about 1.5 percent per year during 1950-1951 to over 2 percent in

the early 1960s. Although the growth rate thereafter started to fall due to (由于) people getting married later as well

as the development of technology, the rate is on the rise again now.

The important thing is not how large the population of the world is, but how fast the rate increases. The world

population increased from 3 billion in 1959 to 6 billion by 1999.The world population will grow from 6 billion in

1999 to 9 billion by 2050. This great growth of the population will create a big problem by the year 2100—there

will be over 10 billion people in the world then.
