America is a country on the move. In unheard?of numbers, people of all ages are exercising  their way to better health. According to the latest figures, 4 percent of American adults exercise regularly-up 12 percent from just two years ago and more than double the figure of 25 years ago. Even non-exercisers believe they would be more attractive and confident if they were more active.

It is hard not to get the message. The virtues of physical fitness are shown on magazine covers, postage stamps, and television ads of everything from beauty soaps to travel books. Exercise as a part of daily life did not catch on until the late 195s when research by military doctors began to show the health benefits of doing regular physical exercises. Growing publicity (宣传) for races held in American cities helped fuel a strong interest in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered equally rewarding-and sometimes safer-forms of exercise, such as walking and swimming, running remains the most popular form of exercise.

As the popularity of exercise continues to mount, so does scientific evidence of its health benefits. The key to fitness is exercising the major muscle groups vigorously (强有力地) enough to approximately double the heart rate and keep it doubled for 20 to 30 minutes at a time. Doing such physical exercises three times or more a week will produce considerable improvements in physical health in about three months.

China’s Ministry of Culture has recommended 10 cyber games(网络游戏) that are suitable for minors to play as part of its drive to purify the on-line environment for the young.

      The 10 cyber games were selected by the ministry’s on-line games censorship committee from scores of games recommended by the Chinese public.l

      The games are all domestic products. They include five role playing games (RPG), four recreation and chess games, and one educational game, such as “Warring States Ⅱ Online,” “Rainbow Island Online,” and “Wonderlands of learning and games.”

       These games have made their way into the final recommendation list because they are considered “healthy” and can “enhance intelligence,” according to the ministry.

       The ministry hoped the list could serve a a guidance for parents to better direct their children in the winter vacation, which usually lasts nearly two months from January to February each year.

       This was the third time for the ministry to publish recommended cyber games list. The previous two were made public respectively in January 2006 and August 2005 with a total of 25 games inlisted.

       In the past few years, on- line games have become the favorite pastime of young people. However, it is argued that such social problems as game addiction, juvenile delinquency (青少年犯罪) and perversion among minors by on-line violence and pornography (色情) have come from an inadequately regulated Internet.

       About 9.72 percent of Chinese netizens between the ages of 13 and 30 suffer Internet addiction, said a report issued last month by the China Youth Association for Network Development (CYAND).

       According to the China Internet Network Information Center (CINIC), the main Internet watchdog, China had 210million Internet users at the end of 2007 and its online population is on course to become the world’s largest at the beginning of this year.

       Net users between 18 and 30 accounted for 49.9percent of the total users. Although the CINIC did not give the figure of those below 18, teenagers and youths have obviously taken up more than half of the total number of net users. And the number of users under age 18 increased rapidly last year, the CINIC noted.

       A. They are expected to help parents to better direct their children in the summer vacation.

       B. They include five RPG, forty chess games and one educational game.

       C. They are suitable for teenagers.

     A. Mor than 105 million.

     B. Less than 105 million.

     C. About 210 million.

     D. 104.79 million.

What can be inferred from the passage?

     A. A lot of Chinese netizens suffer Internet addition.

     B. On-line games can cause a lot of social problems such as game addition, juvenile delinquency.

     C. Parents sometimes have trouble in directing their children about on-line games.

     D. The ministry has recommended 25 games till now.

What’s the best title of the passage?
