      Everyone talks about the weather, but no one does anything about it. It is true.

     People usually begin their talks with "Isn't it a nice day?" "Do you think it will rain?" "What a fine day!"

     Many people think they can tell what the weather is going to be like. But they hardly agree with (同意)

each other. One man says, "Do you see how cloudy it is in the east? It's going to rain tomorrow." Another

man will say, "No, its going to be fine tomorrow."

      People often look for the weather they want. When a farmer needs water, he looks for something to

tell him it's going to rain. He won't believe (相信) anything else. When friends have a journey, they are

sure th e weather is going to clear up very quickly.

      Almost (几乎) everything listens to what the weatherman says, but it doesn't always tell us what we

want, and sometimes he makes a mistake. Still he probably comes closer to being correct than anyone

else.
