    Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big.
And they can eat small animals. One famous meat-eating plant is the Venus flytrap (捕蝇草).
    The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like
the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs.
If a fly touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the
leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
    Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some
places, the ground is very poor. It doesn't have all these important things, especially nitrogen (氮).
Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let's hope that some
of the bigger plants don't get the same idea!

Can we live without salt? No, salt is very important to us, we need salt in our food. Animals need it, too. Most of the salt in our country comes from the sea. People dig very big pools and let sea water in. When the sun dries up the water, people can get salt from the ground. The salt is white, clean and beautiful.

There are a lot of salt wells (井) in Sichuan. A salt well is much like a water well. People bring the water up to the ground and then dry it in big jars over fire. In this way, they get salt.

We can also get salt from salt mines(矿). A salt mine may be found under the ground. Some years ago, people in Jiangxi found a big salt mine and opened it. People there don’t need salt from other places.

Can animals be made to work for us? Some scientists think that one day animals may be taught to do a number of simple jobs. They say that in a film or on TV we may see elephants, or monkeys, dogs, bears, or Other animals doing a lot of things. If you watch carefully, you may find that those animals are always given something to eat in return for doing them. The scientists say that many different animals may be taught to do a number of simple jobs if they know they will get something to eat in return. Of course, as we know, dogs can be used to guard a house, and elephants can be used to do some heavy jobs. And we can also teach animal to work in factories. Apes(猿猴), for example. have been used in America to help make cars and scientists believe that these large monkeys may one day get in crops and even drive trains.
