Now satellites are helped to forecast（预报）the 77．      

weather. They are in the space and they can reach              78．      

any part of the world. The satellites take photos for the      79．      

atmosphere（大气层）because weather formed there. They       80．      

send their photos to the weather station. But scientists 81．      

can see the weather of any part of the world.

Today nearly five hundreds weather stations in    82．      

sixty countries accept satellite photos. Scientists          83．      

compare the new ones from the earlier ones. Perhaps  84．      

they may find that the clouds have been changed        85．      

during the last few hours. This may mean that            86．      

the weather on the ground may soon change too.
