題目列表(包括答案和解析)

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（大氣）, because this is where the weather forms. They send these pictures to the weather stations. So meteorologists（氣象學(xué)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）.

1.Satellites travel ___________.

A．in space

B．in the atmosphere

C．a(chǎn)bove the ground

D．a(chǎn)bove space

2. Why do we use the weather satellites to take pictures of the atmosphere?

Because ________.

A．the weather satellites can do it easily

B．clouds form there

C．the weather forms there

D．the pictures can forecast the weather

3.Meteorologists forecast the weather ________.

A．when they have received satellite pictures

B．a(chǎn)fter they have compared new satellite pictures with earlier ones

C．before they received satellite pictures

D．during they study satellite pictures

4.Maybe we’ll soon be able to forecast the weather for ________.

A．one day

B．two days

C．five days

D．seven days or even longer

5.The main idea of this passage is that satellites are now used in ______.

A．taking pictures of the atmosphere

B．receiving pictures of the atmosphere

C．doing other work in many ways

D．weather forecasting
