Question

Now satellites(衛(wèi)星)are helping to forecast(預(yù)報(bào))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(形成)。They send these pictures to the weather station. So meteorologists(氣象專家)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 meteor- ologists compare(比較)them with earlier ones. Peerhaps 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 be ablet to forecast the weather for a week or more ahead(提前)
小題1:Satellites travel__________.
A in space           B in the atmosphere
C above the ground    D above space
小題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
小題3: Meteorologists forecast the weather________.
A when they have received satellite pictures
B after they have compared new satellite pictures with earlier ones
C before they receive satellite pictures
D while they study satellite pictures
小題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
小題5:The main idea of this passage is that satellite 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

小題5:D

小題1:本文第一，二兩句為Now satellites(衛(wèi)星)are helping to forecast(預(yù)報(bào))the weather. They are in space and they can reach any part of the world.所表示的含義為衛(wèi)星有助于預(yù)報(bào)天氣，在太空中，故本題選A。
小題2:本文第三句為The satellites take pictures of the atmosphere(大氣), because this is where the weather forms所表示的含義為天氣衛(wèi)星拍攝大氣照片，因?yàn)樵谶@個(gè)地方是大氣構(gòu)成的地方，故本題選C。
小題3:本文第二段第二行為When they receive new pictures,the meteor- ologists compare(比較)them with earlier ones. Peerhaps 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所表示的含義為氣象專家通過把衛(wèi)星拍攝的照片和之前的照片作比較，最終得出預(yù)報(bào)的天氣，故本題選B。
小題4:本文最后一句為perhaps , they may be able to forecast the weather for a week or more ahead(提前)，所表示的含義為我們很快將能夠?qū)?天甚至更長(zhǎng)時(shí)間的天氣作出預(yù)報(bào)，故本題選D。
小題5:本文主要談?wù)摿颂鞖庑l(wèi)星的有關(guān)情況，以及天氣衛(wèi)星如何被使用在天氣預(yù)報(bào)中，故本題選D。
