英語(yǔ)演講的主題

Today, my topic is,“On cooperation.”

Families specialize in their tasks by piding the work among the different members according to what they are best qualified to do.

For example,mothers cook, children wash dishes and make beds, fathers mow the grass and paint the house. By doing the same thing again and again, and by close cooperation, a family is able to work faster and get more work done than if just one does many kinds of tasks.

Similarly, it is“cooperation”that makes our complicated modern society work.
