B:I'm afraid so.I think traffic is the most serious challenge of living in a big city.
A:I agree with you.And I think pollution is also a big challenge.I find that almost everything is polluted around us-- food,water and air.
B:You are right.Maybe we should live in the country rather than in the city.
A:That's a beautiful dream!You see,we work here and we can't live too far away from our work place.
B:Maybe we can work and live in the country if we don't expect the modern life .
A:It seems like a good idea!But now I hope we can get to the company quickly.

the pressure from work is the most serious challenge of the city life .the compete will be very serious.,but we shouldn't give up .we must work hard and hard.
