活动3【活动】Think　About　It
Teacher: Do all living things on the planet depend on one another? What does “depend” mean in Chinese?21·世纪*教育网
Students: “Depend” means 依赖.
Teacher: Right. So when living things depend on one another that means they rely on or need one another to survive. For example, if all the animals in the world died, would that affect us?
Write the words die and dead on the board. Explain.21*cnjy*com
Students should master these words.
Students: Yes, because we eat animals for food, and we need food to live.
Teacher: Correct. How else do living things depend on one another?
Write down the students’ responses and make a list of things on the board.
Students: People and animals need the tress to breathe. / People and animals use trees and other plants to make their homes. /Animals provide people with food and clothing. /Some animals eat plants to live while others eat other animals.
Teacher: Excellent work. Those are all very good answers. All animals and plants live off other animals and plants in nature.

Students should master this phrase.
Teacher: Now what do you think happens when pollution and waste destroys parts of nature? For example, when forests are cut down or when water becomes so polluted that you cannot drink it.21*cnjy*com
Students: Animals, plants and people might die.
Teacher: That’s right. If the water in a lake were polluted, then the fish in that lake might die off. That means all the fish that lived in that lake would be dead.
Write the phrase die off on the board .Explain.
Students should master this phrase.
Teacher: But if all the fish die off, then all the other animals that eat those fish to live would also die off.
It would be very sad. So what can we do for nature to make sure no animals or plants die off?2·1·c·n·j·y
Students: Recycle. / Reduce. / Reuse. /Take care of our planet.
Teacher: That s right. Good work.
