Hi,
1. The prompt ask you to compare the countryside and the big city. But you do not mention any information of the countryside in the introduction. I strongly suggest you talk about the countryside in the first paragraph.
Nowadays living is possible on every place of the world, but still there are some differences amoung them.
This opening sentence is too broad and subjective. Living is possible on every place in the world?
How about a volcano?
2.
or instance in my country the best schools,universities and institutes are located in cities
I think you can clearly tell the readers the name of the country and cities in your example.
3.
Your second paragraph is about education.
Your third paragraph is about entertainment.
Your forth paragraph is about the Internet.
However, in the last paragraph, you only mention entertainment.
As I see, the summary is incomplete because you do not summarize all the three points you suggested.
4. "Internet" is a proper noun, so you have to capitalize "I".
Good luck
