Model Essay 30-1
The city and the countryside are similar in some ways，but there still exist great differences in several areas．Generally speaking，the city and the countryside differ mainly in the fields of environment，transportation，public health service，education and entertaintment．
First of all，in the city public transport is good and brings people to almost any place in a short time and for little money while travelling in the countryside is difficult and costly．On the other hand，heavy traffic and business activities in the city pollute the environment whereas the air in the countryside is fresh and clean and filled with bird songs．Secondly，people in the city can get advanced education；However students in the countryside can not．What's more，if city dwellers are ill，it is easy for them to get treatment in a well-equipped hospital；On the contrary，the rural population has to travel long distances to see a doctor．Finally，the many stores，cinemas，dancing halls and restaurants make life in the city colorful as opposed to the simple and some people even say boring life in the countryside．
As we have seen，there are still great differences between the city and the countryside，but further economic development will certainly reduce the gap between the two in the near future．
