Unit 5 The power of nature
导读：海啸，地震，干旱，泥石流，台风……，地球母亲一次又一次的向人类发出警示： 人类应该为自己的行为负责！
Task: Let's take action！
Man and nature
It is believed that humans are the real offenders of natural disasters. People, though the victims in these natural events, pays for the debt that their excessive development has brought about. Natural disasters can be prevented, but the dreadful injury on people can hardly be healed. Judging from these disasters, can we come to a conclusion that today's topic should not be the summary of yesterday's lessons, but a foresight on what will happen in the future.
Now, we have three missions to undertake. It is
necessary to break away from the stereotype that we are used to: embark on solving the problem the time it occurs. Then, redesign our assignment to make it more sustainable and environmentally friendly. Last and the most important, every country, both the developing and the developed ones, should get rid of their bad pattern of development and facilitate collaboration as one power to solve the natural problems.
