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.
What is compared to "electricity" in paragraph 4?
选项
A、Sunlight.
B、Water.
C、Air.
D、Carbon.
答案
A
解析
细节题。题干意为“与第四段中的‘电力’作对比的是什么?”由第四段第二句话中的“They use sunlight for this work…”可知,它们利用阳光完成这项工作,由此可以看出“电力”是用来和“阳光”作对比的,故A正确。
