江城子·癸酉春社
王 炎①
清波渺渺日晖晖，柳依依，草离离。老大逢春，情绪有谁知？帘箔四垂庭院静，人独处，燕双飞。
怯寒未敢试春衣，踏青时，懒追随。野蔌山肴，村酿可从宜。不向花边拼一醉，花不语，笑人痴。
王炎：生于公元1138年，到癸酉年（1213年）已经七十五岁。
Jeans have become one piece of clothing worn by the most people in the world. Everybody wears them, from the farmer to the lawyer and from models to housewives. But why have jeans become so popular？You'll get many answers. For some people they look cool, for others jeans are just comfortable. Jeans were first stronger trousers made for farm workers in the states of the American west. In the eastern part of the US jeans were hardly worn at all. They were connected with farm people and the workers. So the rich wouldn't like to wear them. It was James Dean and Marlon Brando that made them popular in movies and everyone started to wear them. They were a symbol of the rebellion of young people during the 1950s and 1960s. So these new trousers were not allowed in American schools and sometimes in theatres and cinemas. As time went on，jeans became more acceptable. American people in Europe and Japan often wore them when they were not on duty to show that they were Americans. The trousers showed the world a happier way of life, something that people needed, especially after what they had gone through in World War II. Jeans had other advantages as well. They didn't need to be washed as often as other trousers and women didn't need to iron them. This became more important as more and more women started working and had less time for housework. Today jeans are an important part of our lives. They are always washed a few times before they are sold to give them a faded look.
