Every country has its heroes. The heroes are the people the nation and especially the young people admire. If you get a list of the heroes of a nation, it will tell you the potential(潜力)of that nation.

Today in America, if you ask the high school students to list their heroes, their choice would probably fall into three groups. The first group of heroes would be the rock stars-the people connected with rock music. There is no doubt that such people do have talent(天才)but one wonders if one should hold up rock stars as a model. The rock stars too often are mixed with drugs and their personal life is not all that good. The rock stars are rich and wear the latest fashion styles. However, one should seek more in a hero than such things as money and good clothes.

A second type of hero for the American youth is the sports star. Again you have a person who has a great ability in one area-sport. However, too often the personal life of the sports star is a bit of a disorder. Too frequently drugs and drinking are a part of life of the sports star.

A third type of hero is the TV or movie star. This person may have lots of acting talent and is quite handsome. However, the personal life of too many actors is quite sad and they should not be held up as a model of young people. Today, the rock star, the athlete, and the actor all have become the models of the youth in America. Really, do you hear a young person say that his hero is a doctor, a teacher, or a scientist? These people are not rich and do not wear fashionable clothes. However, they are talented people who work hard to make the world a better place for everyone.

What is really sad is that the young try to imitate(模仿)their heroes. They like to wear the same clothes and　follow their styles. If the heroes of today for the American young people are limited only to rock stars, athletes and actors, the future does not look too bright.

United States President George W. Bush is expected to issue a directive in the next few weeks. It will give the US Air Force a green light for the development of space weapons, US media reported last week.

This would potentially start a new global arms race, some experts have warned.

To keep that from happening, last Wednesday the White House explained that it was not considering putting weapons in space. It said it was making a shift in US space policy to allow for protection of satellites.

But some defense analysts and arms control advocates argue that the policy will pave the way for the US to put both defensive and offensive( 攻击性的)weapons in space.

“No one should be fooled,” said Theresa Hitchens, an American weapons expert.

The US is now restricted by a 1996 directive　signed by President Bill Clinton. Plans for space weapons were vetoed( 否决)by the Clinton cabinet. The directive emphasized the peaceful use of space , in agreement with almost unanimous(一致的 )global opinion.

The US military has placed importance on space and has sent up numerous satellites for troop communications and to provide intelligence and data to guide bombs to their targets.

The US Air Force wants to develop space- based weapons that could strike targets anywhere in the world within 90 minutes of receiving the order to open fire.

These new weapons under development cover a wide range. They include hunter- killer satellites and orbiting weapons. And they use lasers, radio waves, or even dense metal tubes, known as “Rods from God”, dropped from space to do the damage.

There are many barriers to the setting up of this kind of program, experts say.

First is the coast. It is estimated that the budget may be US $220 billion to US $ 1 trillion( 万亿).

The technical difficulties of developing reliable space weapons are also a problem.

And, the program will draw strong criticism from around the world. Experts worry about starting a space arms race.
