高中三年级英语(人教版)全一册 Unit 15 Integrating Skills

　　In the 1930s many movies in the USA showed cowboys in Western America wearing jeans. Cowboys had a reputation for living wild and free, and many young American men dreamed of a similar life, so they dressed to look like their film star heroes. In World War II these men became soldiers and were sent to fight in other countries. They took their favourite pair of jeans with them to wear in their free time, and this is how American jeans were introduced to the world.

　　After the war ended, American teenagers started to make denim jeans their own unique item of fashion. In the 1950s jeans and rock 'n' roll music became symbols of the new youth. Adolescents at that time enjoyed new and different things. They listened to the new type of music and they wanted to look different too. Many schools in the USA did not approve of students wearing jeans to school and they forbade them. This made jeans even more popular in the evenings and at weekends.

　　Since then jeans have been through many different changes in style. Some years they have wide legs; at other times narrow legs are the fashion. Tight fitting or loose; coloured, dark blue or light blue; decorated with holes, paint or flowers --jeans are constantly changing. In the 1990s a new material was added to the cotton to make it stretch and give an even tighter fit over the bottom and legs. More recently it became popular to wear jeans that looked very old and companies started to produce new jeans that appeared to have been worn for several years and washed many times.
