　　Topic sentence 1: The glamorous city life allures lots of human resources to move to/agglomerate in the city, taking major contribution to the gap. (20 words) Supporting sentences: In the city, there are many advantages to attract those talented people to settle down--more job opportunities, cultural activities, sporting events, you name them. Therefore, even those well-educated people who are originated from the country intend to lead a dynamic city life instead of returning to face the static country view.

Consequently tourism as well as housing in the countryside will be boosted, and the difference between the city and the country would be minimized. (94 words)

If both issues were tackled properly in the countryside, gap between the city and the country would never be overwhelming.(48 words)
