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!

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering(不开花的) plants.
Flowering plants can make seeds(种子). The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit.
Most non-flowering plants do not grow from seeds. They grow from spores(孢子). Spores are very, very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores fall on wet and shady(阴凉的) places, they usually grow into new plants.
【小题1】What fact does the passage lead you to believe?

A.Of all living things, animals are most important.
B.Spores are seeds.
C.All fruits of flowering plants have seeds.
D.Without plants, man will die out.
【小题2】The paragraph following the passage will be about ________.
A.how plants can make food from air
B.how spores grow into new plants
C.why some plants have no seeds
D.why non-flowering plants are more important than flowering plants
【小题3】This passage is most likely to be taken from ________.
A.a story bookB.a novel
C.a science magazineD.a laboratory report
