G: Dad, I heard a new factory is going to be built in our city. How great it will be! 

M: That’s what I’m worried about.  

G: Why? Don’t you think it is a good thing? 

M: I don’t think so.  

G: But my teacher told us that a new factory would give us a lot, and bring a lot of jobs to school-leavers.  

M: It will also bring more pollution to our environment. 

G: I don’t understand.  

M: In cities, pollution is mainly from factories. The waste gas from these factories pollutes the air, and we breathe the polluted air.

M: That’s a difficult question.
