      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!
