<题目>C
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.
⑤Seeds can’t walk. They can’t run. But they can travel with the help of wind,water and animals.
11. What will happen if new plants are crowded?
A. Some of them will die. B. Some of them can live better. C. Some of them can grow taller.
12. What does the underlined word “them” refer to?
A. Wings. B. Seeds. C. Plants.
13. What can help the seeds to travel according to the passage?
A. Leaves,roots and flowers. B. Animals,water and wind. C. Birds,stickers and wings.
14. Which can be the best title for the passage?
A. The travel of the seeds B. The parts of the plants C. The kinds of the seeds
15. What’s the structure of the passage?
