9、This report presents facts of home computer used by a group of young people. It is a common belief that teenagers today know about  1  and are familiar  2  using them in all their lives. We decided to try to  3  if this was true.

  We questioned thirty people between 14 and 18. All the teenagers we  4  said they had computers at home. We asked them how much time they spent on their computers in an average week,  5  we were most interested in 6  they used their computers  7 .

   The average time  8  on a computer in a week was about 12 hours, with the highest user average 32 hours and the lowest user  9  5 hours. There was  10  important different between boys and girls.

All of the people questioned said they regularly used the computer to  11  games. Fourteen told us they did some word-progressing at home, but not very much. Only two said that computers  12  them with their studies,  13 eight people told us they kept address and telephone numbers on their computers  14  used them writing diaries. Only three people said they were learning to program computers. But  15  of the people used their computers for  16  purpose.

The results make it known that average computer use is quite high  17  teenagers. They also show quite clearly that computers are seen by most young people  18  little more than game machine. The only important uses are for word-procession and organizing address lists. It  19  to us that, although computers are popular with British youths, they have not  20  become useful tools in their daily life.

6、Commencement (毕业典礼)is a time for idealism.

But economic reality is cruel everywhere; especially for new college graduates. They have been told repeatedly that a college degree is an open sesame (芝麻) to the global economy, But that's not necessarily so, according to new research by two economists at the Massachusetts Institute of Technology, Frank Levy and Peter Temin.

It is true that people with college degrees make more money than people without degrees. The gap has narrowed somewhat in recent years, which is disturbing. But the earning power of college graduates still far outpaces that of less-educated workers.

The bad news, though, is that a college degree does not ensure a bigger share of the economic pie for many graduates. In recent decades Mr. Levy and Mr. Temin show, only. college-educated women have seen their income grow in line with economy wide gains in productivity (生产). The earnings of male college graduates have failed to keep pace with productivity gains.

 Instead, a huge share of productivity growth, which expands the nation's total income, is going to Americans on the top of the income scale. In 2005, the latest year with available data, the top 1 percent of Americans—whose average annual income was $1.1 million-- took in 21.8 percent of the nation's income, their largest share since I929.

 Administration officials, and other politicians and economists, often, believe that income inequality, reflects an education gap. But Mr. Levy and Mr. Temin show that in the case of men, the average bachelor's degree is not enough to catch the rising tide of the global economy.

 They argue that the real reason that inequality is worsening is the lack of strong policies that broadly distribute economic gains. In the past, for example, a more progressive income tax and unions promote equality. Positive measures have also helped and probably accounts, in part, for the pay growth of college-educated women. But such measures have been eroding and new ones have not yet emerged, making the income gap even greater.

 Mr. Levy and Mr. Temin conclude that only a new government policy can restore general prosperity. That's a challenge to the nation's leaders and today's graduates. America needs them to contribute to the development of the nation in a global economy.
