问题 Satellites travel______. [br] Meteorologists forecast the weather______.
选项 A、when they have received satellite pictures
B、during they study satellite pictures
C、after they have compared new satellite pictures with earlier ones
答案 C
解析 题干的意思是气象学家何时预报天气。A的意思是当他们接收到卫星图片时，B的意思是在他们研究卫星图片的过程中，C的意思是在他们和早期的卫星图片比较后。文中的相关细节为"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 that the weather on the ground may soon change，too．In their next weather forecast， the meteorologists can say this．”，即气象学家收到新的图片和早期的图片相比较，也许他们会发现在过去几个小时内大气的变化，这也同时意味着地表的天气状况也将发生变化，因此在下次气象预报中，气象学家将预报这些变化。故正确答案为C。
