     When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived

on a farm. In the winter especially, we wear quite out off from the outside world. As soon as I left school, I

packed my bags and moved to the capital. However, I soon discovered that my life has its too.

     One big disadvantage is money. It costs so much to go out, not to mention basics like food and housing.

Another disadvantage is pollution. I suffer from asthma (哮喘), and the air is so that I am afraid to go outside.

Then there is the problem of traveling round. Although I have a car, I seldom use it became of the traffic jams.

One choice is to go by bicycle, but that can be quite dangerous.

     Of course there are advantages. First, there is so much to do in the city, whatever you tastes in culture or

entertainment (娱乐活动). Besides, there are wonderful jobs and greater chances of moving to a more important

job or position. Finally, if you like shopping, the variety of goods is very surprising-and, what is more, shops

are often only a short walk away.

     Is life better then, in the city? Perhaps it is, when you are in your teens (十几岁) or twenties. However, as

you get older, and especially if you have small children, the peace of the countryside may seem preferable. I

certainly hope to move back there soon.
