Ss: Pollution.
T: What kinds of pollution do you know?
Ss: Air pollution, water pollution, land pollution, noise pollution…
（设计说明：在课的开始部分，用一段关于美丽地球的视频引领学生们去感受生态和谐的大自然的美好，为接下来所要谈论的地球所面临的严峻的污染问题做了对比性的铺垫，从而便于激起学生们强烈的环保意识。）
2. Discussion.
Show the Ss some pictures of some kinds of pollution, and ask them to describe the pollution, find out the reasons, and give possible ways to cut down the pollution according to what they have learned in Unit 13.

What is causing the problem?
What should we do to cut down the pollution?

范文赏析:
Dear Sir/ Madam, Environmental problems are becoming more and more serious all over the world. With the development of the society, there are too many cars on the streets in our city. Cars have made the air unhealthy for people to breathe. Black smoke and poisonous gas are given off by factories. Factories also put waste into the river. And wherever we go, we can find rubbish.
Now more and more people have realized these problems. I think that governments should close down the factories and develop laws to stop people from driving cars every day. I suggest everyone in this town should help to clean up the river and the streets. We should call on everyone in the town to throw rubbish in the dustbins.
I hope the problem will be solved in the near future and our home will become better and better.

Homework My Low?carbon Life
It's our duty to protect the environment.
As we all know, with the global warming and energy consumption, the environment is becoming worse and worse.It is very important for us to start with a low?carbon lifestyle.But how can we live a low carbon life? Here are my ideas.
Firstly, it is a very good idea for us to go to school on foot instead of by car.It is good for the environment and our health as well.Secondly, remember to turn off the lights, fans and computers when we leave the classrooms.Thirdly, it is important for us to turn off the tap when we finish using the water.We can reuse water, too.For example, we can reuse the water to water the flowers or trees.At last, try to use the cloth shopping bags instead of plastic bags when we go shopping.(In addition, it is important for us to use fewer fast food boxes or chopsticks so that we can reduce the white pollution.)
I believe our life will become better and better if we can do these things.
Lower carbon, happier life.Let's take action.
