[ 英语 ] In Britain today, is it possible to tell a pe


In Britain today, is it possible to tell a person’s class just by looking at him? Physical details alone tell us about health, diet and the type of work a person does. A hundred years ago the working class often looked unhealthy, small and they were either too thin or too fat. The upper classes were often tall, sporting types who were used to a good diet and looked healthy. Today living and working conditions have improved, and such descriptions are no longer true. People are taller now than a hundred years ago. Everyone in Britain today is able to have free medicine, a good diet, acceptable working conditions and enough rest and leisure.
The clothes people choose to wear, however, do provide information about their backgrounds. Expensive clothes look expensive and show their wearer is rich. Clothes can provide other clues as well. The upper classes appear to be less interested in fashion and wear good quality clothes in non-bright colours, made of natural material like wool, leather and cotton. Lower working-class people often choose clothes in bright colours, made of man-made materials. A sociological explanation for this would be that colour and interest are missing from their lives, and therefore any opportunity to produce this is taken.
Clothes are available at a price within most people’s reach. New clothes make the wearer feel good and show some degree of wealth to the outside world. Today it is the younger people who spend most money on clothes. Fashion is no longer for the upper classes and the rich. Young people from all social classes spend a lot of money on clothes. Some new fashions are started by working—class people who want to look different and feel important. They want people to look at them.
1. In the past, a person’s appearance could not tell other people about his ________.
A. health          B. diet             C. occupation          D. habits
2. The clothes people choose to wear tell us about their ________.
A. education          B. richness         C. backgrounds        D. hobby
3. A working—class person may start a new fashion because ________.
A. she wants to draw the attention of other people
B. she wants to look different and healthy
C. she wants to show their wealth
D. she wants to show their taste
4. Which of the following statements is NOT true?
A. Expensive clothes look expensive and show the wearer is rich.
B. Working—class people prefer clothes in bright colours because they lack colour in their lives.
C. Today, it is still the upper class people who spend most money on clothes.
D. Today, fashion is no longer for the upper classes and the rich.
