A lift is wonderful. It is really only a small room. Rooms usually stay in one place. Lifts travel up and down all day long.
Sometimes a worker stands in the lift. He or she operates it up and down. In modern lifts there is no worker. The people walk in. They know what floor they want. They push a button and the lift goes to that floor. It is all very fast and easy.
Lifts are very important to us. Why? Think about a tall building. Maybe it has twenty floors. Maybe it has fifty or more. Who can walk up all the stairs? Maybe people can climb them one time. Can someone climb thirty floors to an office every day? Can small children walk up to their room on the twenty-fourth floor? Can their mother and father carry food up all those stairs? Of course not.
We can have high buildings because we have lifts. We could not have all the beautiful tall buildings in the world without lifts. They are really wonderful.

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.
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. (A) They can open and close very quickly. Inside the leaves, there are three small hairs. If an insect touches one of the hairs, the leaf closes quickly. The insect cannot get out. In about half an hour, the leaf presses(挤压) the insect until it is dead. Then, the plant covers the insect with a special liquid (液体). Slowly, the plant eats the insect.
(B) Plants are living things that have leaves and roots and grow in earth. Most of them get energy from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all the important things that plants need, 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!
