【正确答案】Candidates:
A: What does the first picture show?
B: This picture shows that a peasant is herding cattle beside a river. The cattle is thirsty and wants to drink. But the poisonous waste water is poured into the river directly from a factory without filtering. Thus the water, is polluted. I think if the cattle drank the water, it would die. Do you think so?
A: Yes, I agree with you. The water discharged from most factories is badly polluted, which contains lots of poisonous chemicals. I think the peasant is very clever. In order to get clean water for his cattle, he shouts at the factory, "The inspectors are coming." Can you describe what happens in the second picture?
B: In the second picture, we can see that the river becomes clean and the cattle can drink the water now. Do you know the reasons?
A: The factory knows that the government has made laws to forbid factories to pollute the water, so when the peasant shouts that the inspectors are coming, the factory stops pouring waste water to the river. I think the most important thing is that we should educate people and arouse the people's awareness to protect environment.
B: Yes, I also think so. Since people are dependent on water, they should be involved in preventing pollution. Recently, certain counter measures have been taken, but everyone should know that polluted water is hazard to all of us.
A: Yes. If people continue to pollute their environment, human on the earth will not survive.
