Our life in the large city is more beautiful than the country or in the town. First of all there are no any conveniences in country houses. The second reason is that in a large city we have many ways of  getting an education such as a great number of different schools, colleges, institutes and universities and there are many big shopping centers in a large city too. You can easily find any job in a large city because there many plants andfactories in it. If you are ill you can go to a big hospital and get any medical help. And at last there are many places where we can have a fun,  for example cinemas and theatres, clubs, parks, squares. That is why I would like to live in a large city.
