英国资产阶级革命从1640年开始，历经曲折，先后经历内战、共和、军事独裁、王朝复辟等阶段，直至1688年革命结束。1689年，英国议会颁布法案，限制国王行政、司法等权力。1701年，议会颁布《王位继承法》，规范王位继承问题，规定国王的一切决定须经同意该项决定的大臣签署后才能生效。18世纪中期，英国基本确立了以法律规范国家权力的近代民主制度——君主立宪制。

Teens Enjoy Reading
     According to a survey on reading conducted by the U.S. National Education Association (NEA), young Americans say reading is important—more important than computers and science. Over 50% of the twelve to eighteen years old children interviewed said they enjoy reading a lot. Seventy-nine percent find it stimulating and interesting, and 87% think it is relaxing. Most of those surveyed (68%) disagree with the opinion that reading is boring, or old-fashioned.
Teens Read Variety of Material
    Over half the teenagers interviewed said they read more than ten books a year. The results also showed that middle school students read more books than high school students. Most teens (66%) like to read fiction, such as novels and stories. Only 26% were interested in non-fiction, such as biographies and history books. Sixty-four percent of students liked reading ‘stories about people of my own age’ as their favorite topic. Mysteries and detective stories came second on the list at 53%. Just under 50% said they were interested in reading about their own culture and heritage.
Other Interests
    Of the teenagers who took part in the survey, 49% said that libraries are where they get most of their books. However, many complained that their school libraries do not have enough up-to-date, interesting books and magazines. Even though many teenagers in the U.S. enjoy reading, they still have other interests. When asked which activity would be the most difficult to give up for a week, 48% said listening to music. TV would be difficult to give up for 25% of those surveyed.
  ____
    Another survey which is published by www. SmartGirl.com studied the differences between teenage boys' and girls' reading habits. According to the report, more girls than boys read for fun. Many more girls (77%) than boys (6%) read fashion and beauty magazines. More boys (47%)  than girls (7%) read magazines about video games, but an equal number of each like to read adventure stories and newspapers. Girls also read more material about celebrities and social issues such as crime, drugs, or poverty. Boys, on the other hand, read more about sports.
