Have you ever heard anyone say“It’s raining cats and dogs”? It means“It’s raining hard!”
　　But sometimes cats and dogs do drop from the sky! Here’s how it happens.
　　Not so long ago, a country far away had many large rats. The people there said,“We need cats!”So cats were sent to them by airplane. But the country had many mountains. It was hard for an airplane to land. So the cats came down by parachute(降落伞). Did the cats like the ride? They didn’t say they didn’t! And today they are still catching rats!
　　In another country far away, there is snow the year around. People sometimes got lost in it.
　　“We need big dogs!”the people said.“The dogs could find people lost in the snow. The dogs could help bring them home. Where can we get big dogs?”
　　A man across the sea had big dogs to sell.“I will send dogs to you.”He said.“I have some very big ones. They can find people lost in the snow.”
　　He sent the dogs by airplane.
　　But the airplane didn’t land in the snow. The dogs came down by parachute—you guessed it!
　　Did the dogs like the ride? They didn’t say they didn’t! And today they are well and happy. They find anyone who gets lost in the snow. Then they help him get home. Good dogs!
　　Remember it, so you can say,“Yes, it does rain cats and dogs sometimes. They came down by parachute!”

Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.

Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.

This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.
