    Everyone knows Smokey the Bear in the USA!

    ----You see him on TV.

    ----You see him in the paper.

----You hear him on the radio.

 Smokey always wears a forest ranger’s (护林员) hat. And he says the same words over and over, “Be careful! Only you can prevent forest fires!”

   Who first thought of him, and why? His story goes back to 1945. before then, there were many, many forest fires. Big trees were burned down. Land was burned black in many places. Careless people started most of the fires. They did not put out their campfires, or threw away matches that were still burning.

“Let’s tell people something about forest fires! Let’s tell them they often start the fires,” said a man named Mr. Gray.

“Good!” said Mr. Ross. “ Now, what’s the best way to tell them?”

“A friendly bear could tell them,” said Mr Gray.

Everyone agreed. So Smokey was “born”---name, hat and everything! Ever since then, he has had a green job. And he has done it well. People are more careful now because of the friendly bear. Smokey keeps telling us, again and again, “ Put out that match. Put out that campfire! Only you can prevent forest fires!”

Smokey often makes us feel good, too! He says, “ Thanks for being careful.”
