阅读下面短文并回答问题，然后将答案写到答题卡相应的位置上（请注意问题后的字数要求）。

[1]It’s difficult to find a piece of clothing as widely accepted, worn and loved as jeans in the world. The classic symbol of the American West is now a main item in closets around the world. But why?

[2]The reason for jeans’ success has as much as to do with their cultural meaning as their physical construction.

[3]Invented by Levi Strauss and Jacob Davis in 1873,jeans were first designed as work wear for laborers on the farms and mines of America’s Western states in the late 19^th century. They proved extremely comfortable and durable（耐用的）and were soon in high demand.

[4]But the first explosion of jeans into world of casual-wear had more to do with what jeans had come to symbolize.

[5]When they did start to be worn as casual wear, jeans became a symbol of rebellion—the spirit captured by Marion Brando in his 1953 film The Wild One and by James two years later in Rebel Without a Cause.

[6]Many teenagers in 1953 wanted to be Marlon Brando, and Hollywood costume designers put all the bad boys in jeans. Jeans were soon banned in schools from coast to coast which only added to the passion with which teenagers loved them.

[7]But jeans’ popularity kept growing also because they put different classes on a level playing field. They were affordable and hard-wearing, looked good worn as well as new, and didn’t have to be washed often or ironed at all. They suited to the body in a way that matched even the most finely tailored clothes. This became especially important for women because then, and now, they paid more attention to fit. This versatility（多用途）,the ability to become all things to all people ,is the secret to jeans’ survival as a closet item.

人类最伟大的思想，尽在书中。一个没有阅读的学校永远不可能有真正的教育，一个没有阅读的民族是一个没有希望的民族，阅读事关全民素质和文化强国的问题。调查显示，中国人年均读书量为4.5册，日本为40册，以色列为64册，目前很多国家都已对阅读进行立法，如美国《卓越阅读法》，韩国《读书振兴法》等。十八大报告首次将全民阅读战略写入党的政治报告，据报道，我国全民阅读立法也已列入2013年国家立法工作计划。

结合文化生活有关知识，分析开展全民阅读活动对国家有什么积极意义？
