The British show a great love for the countryside and it is really nice and beautiful. A lot of people dream (梦想) about living in the countryside, to enjoy the quiet and the air. Today, many people, both old and young, make the dream come true. But most people have to live in a town or city because that is where the work is.
People of a city are often proud (自豪的) of living in it. People of Manchester believes that there is no better city than Manchester; people of Liverpool feel the same way about Liverpool. Outsiders and passing travelers may be interested in what the difference is between one city and another. Maybe they remember Newcastle because of its bridge over the River Tyne, or Liverpool because of its docks (码头). There is one difference which most people can hear; that is the different ways of speaking and also some words which are used only in one place.
