British society is considered to be divided into three main groups of classes-the upper class,the middle class.and the lower or working class.This is known as the class system and it is important to know something about it if you mean to understand British people and society.Most British people grow up with a deep knowledge and understanding of the class system even if they are not very conscious(意识到的)of it.As a result,more people know which class they belong to and are able to tell which class other people come from by the way they speak,the kind of clothes they wear,their interests and hobbies or even the type of food they eat.

Social class is not only about behavior and attitudes.For example,although many upper class people are rich and may own a lot of land,having a lot of money does not necessarily make a person one member of the upper class.It is also important to come from a particular kind of family,have friends who are considered suitable,have been to a certain type of private school and speak with the right kind of accent.There are people who are poor but who do not think of themselves as working class because their family background,education,political opinions,etc.are basically different from those of most working-class people.Many people do not like the class system but it is impossible to pretend that these differences do not exist or that British people do not sometimes form opinions in this way.
