摘要:The main idea of this passage is that satellites are now used in . A. taking pictures of the earth B. receiving pictures of the atmosphere C. weather forecasting D. doing other work in many ways Passage 27 Paragraph 1 Scientists have learned a lot about the kinds of people need. They say that there are several kinds of food that people should eat every day, they are: (1) green and yellow vegetables of all kinds; fruits and tomatoes; (3) potatoes and other fruits and vegetables; 94) meat of all kinds, fish and eggs; (5) milk and foods made from milk; (6) bread or cereal , rice is also in this kind of food; (7) butter, or something like butter. Paragraph 2 People in different countries and different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether foods are eaten raw or cooked, canned or frozen . It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at eleven o’clock at night. The important thing is what you eat every day. Paragraph 3 There are two problems, then, in feeding the large number of people on the earth. The first is to find some way to feed the world’s population so that no one is hungry. The second is to make sure that people everywhere have the right kinds of food to make them grow to be strong and healthy.

Now satellites are helping to forecast 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. 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)

satellites take pictures of the atmosphere(大气), 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. 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

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 0r 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.
