Everywhere in the world, plants and animals live together. Some animals eat plants they live with. Some plants stay alive because many plant-eating animals have natural enemies that eat them. Rich soil for the roots of plants is produced by worms and other very small animals that live underground. Green plants feed animals and people.
It takes all the plants and animals living together to keep the earth a good place to live in. Plants and animals
trade with
each other. They trade for things they both need to stay alive.
Animals breathe and the air gets changed inside their bodies. When they breathe the air out again there’s something called carbon (碳) in it. Animals can’t use this air again. But plants need carbon. The plants trade fresh air for the carbon they need.
Plants make food from carbon and water. They use sunlight for this work, just as a machine uses gas or electricity to keep running. The plants store the food they make inside themselves.
But what do the plants get in return? Many things. Plants make food from the carbon and other things that come from animals’ bodies. Insects like bees carry pollen (花粉) from one flower to another and the pollen forms seeds. Birds and other animals eat the fruit in which seeds grow and often drop the seeds where they can grow up into new plants. So animals help the growth of new plants.
Which of the following is the closest in meaning with "trade with" in paragraph 2?
选项
A、live for.
B、give to and take from.
C、stay with.
D、teach and learn from.
答案
B
解析
由第二段最后一句“They trade for things they both need to stay alive.”可知,它们交换彼此需要的东西来维持生存,据此可以推断出画线部分的含义应该是互相交换的意思,故选B。
