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?”

Many people think they can tell what the weather is going to be like. But they hardly(几乎不) agree with each other. One man may say,“Do you see how cloudy it is in the east? It’s going to rain tomorrow.”Another man will say,“No, it’s 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 travel, they are sure the weather is going to clear up very quickly.

Almost(几乎)everyone listens to what the weatherman says, but he doesn’t always tell us what we want, and sometimes he makes mistakes. Still(仍然), he probably(或许)comes closer to being right than anyone else.
