①Plants have roots, leaves, and flowers. They have seeds, too. New plants grow from seeds. Some seeds fall on the ground. New plants grow next to the old plants. When plants grow this way, they are too crowded to get enough sunshine and water. So some of them die. But some plants spread their seeds even far from where they live. These seeds grow in new places. There are many ways of the seeds’ travel.
②The wind helps seeds to travel. Some plant seeds have little wings. When the wind blows, the seeds fly away. Soon they fall to the ground and new plants may grow there. Some plants dry up. The wind pulls them from the ground, but they are so big that they can’t fly. They roll along the ground, dropping off their seeds.
③Other plants grow near the water. Their seeds drop into the water and go away with it. They may travel many miles before they stop.
④Some seeds have special parts called “stickers”. The stickers help the seeds travel far. How These seeds wait for an animal to walk by. Then they stick into its fur to get a free ride. Sometimes it’s a long trip. Birds carry some plant seeds to new places, too.

Bamboo is a wonderful plant for many people around the world. 6 People make tables, clothes, medicine, and musical instruments with it. Pandas may eat bamboo every day, but people can also eat it.
7 Some bamboo grows so quickly that people say they can watch it grow. The speed of growth depends on the type of bamboo, the earth and the season. Normal bamboo grows 3—10 cm a day. It usually grows in tropical (热带的) areas. 8 Bamboo plants are found in Asia, Australia, parts of Africa, and South America.
One of the world’s oldest building materials is bamboo. Like today, people use it because it’s very strong. They used it to build houses, boats, and bridges. The Chinese made a bamboo bridge over the Min River in Sichuan, China almost 1000 years ago. 9 Also, bamboo is still used to make houses today, especially in China and Philippines.
As a part of history, bamboo is very important. The great scientist Thomas Edison did not invent the light bulb (灯泡), but he made it perfect. He wanted the material inside to burn for a long period of time. He tried over 1000 different types of materials. 10 One day, he tried to use a piece of bamboo and the light bulb lit up for over a thousand hours. This invention helped other scientists to make the modern light bulb we use today.

阅读下面短文，简略回答问题。
Can plants eat people Maybe 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 (压) the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
Plants are living things that have leaves and roots and grow in earth. 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!
26．Is the Venus flytrap a plant or an animal
27．What’s inside the leaves of the plant
28．Where do most plants get what they need
29．What do you think of the flytrap Why
30．What does the writer mean by saying the underlined sentence Unit 4 Amazing Plants and Animals
