Our cities are getting bigger and bigger as more people move from the country to the city．There are lots of reasons why they do this-mostly it is to find work，because all the big companies are in the cities and they need lots of people to work there．When there are lots of people living and working in a city，they need things like restaurants，shops，hospitals and schools，too．These are all more jobs that people need to do．There will be lots of transport in the city to move all the people around．Everything you could want will be found in a city：government offices，museums and art galleries，cinemas，big restaurants and parks．

Unfortunately the city is much busier，more expensive，and more dangerous than the country．The air is not so healthy because of all the cars and trucks on the roads．There are so many people that it is not as friendly-you cannot get to know everyone as you do in the country，and people may get lonely．You do not have much room in the city-most people live in apartments-not houses，and they do not have gardens or lots of space，and because of all the people there is also a lot of noise．

The country is much more friendly as everyone knows each other．It is much cheaper to live and there are less dangerous people than you find in cities．And perhaps the best thing is that you can have a big house with a garden and it will be very quiet．But there are not many jobs or services there．There are also not many shops，schools or hospitals．And it is hard to get around．

Every person is different，but more and more people choose to live in cities because there is so much to do there．What do you think about the city？
