1. Listen and read
Nick: Your home village is so beautiful. There are so many trees, flowers and birds.
Mi: Yes, that`s why I like coming back here on holiday.
Nick: Mi, what`s that factory? It looks new.
Mi: I don`t know. There wasn`t a factory here last year.
Nick: Mi, look at the lake! Its water is almost black.
Mi: Let`s go closer. ... I can`t believe my eyes. The fish are dead!
Nick: I think the waste from the factory has polluted the lake. The fish have died because of the polluted water.
Mi: That`s right. If the factory continues dumping poison into the lake, all the fish and other aquatic animals will die.
Nick: Ahchoo!
Mi: Bless you! What`s the matter?
Nick: Thanks. Ahchoo! I think there`s air pollution here as well. If the air wasn`t dirty, I wouldn`t sneeze so much. Ahchoo!
Mi: I`ve come up with an idea about our environmental project! How about giving a presentation about water and air pollution?
