The number of people in the U.S.who choose not to marry is growing every year.By 1996 about 25 million people over the age of 21 years were living alone.50 years ago this number was less than 2 million.One reason for this is because people are getting married at a much later age than in the past.The average age for men is now 27 years.For women it is about 25 years.Another reason is the increase in the number of divorces.Living alone has become more acceptable in American society.In the past people sometimes think those who lived alone were a little strange.These days,however,several of the most popular TV shows tell the story of men and women who can't meet "the right person" and who plan to be single forever.Many such single people (especially women) feel that they are more free to pursue (追求) their careers (事业) than those who are married.In a way these people are married to their jobs.1.About 23 million people over the age of 21 were not married in America by 1996.A.TB.F2.Most of men usually get married at the age of 27 in America.A.TB.F3.In the past,people thought it was impossible to live alone.A.TB.F4.Some people in America wouldn't like to get married,because they can't meet "the right person".A.TB.F5.More and more people in the U.S.choose not to marry.A.TB.F
