     Being a youth is one thing, and being a good one is another. A good youth should have these qualities

(品德): First of all, health. A healthy body is the best riches. Without it, nothing can be done well. If you

are poor in health, you will have to take medicine day after day. You can even work, do sports and so on.

Secondly, one must be of good quality. Always do something good for others. Help those in trouble and

care about the people around you. If everyone did the same, what a wonderful world this would be! Thirdly,

one must have the ability (能力) to work with others. Cooperation and communication (合作和交流) are two

important keys to better human relations. Everyone needs friends because no one can live through life alone

or do everything he wants to.

     Besides the examples above, patriotism is the one we should never forget. Patriotism means a love for

one's country. It is one of the highest qualities of human's. Everyone should love his own country. But people

sometimes think that patriots (爱国者) must be fighters or that they live in a time of fighting for their country.

That is wrong. A good youth's work is not only fighting. A good youth will do the things his country asks him

to do. I think a good youth of today should also have some training in art. If everyone can enjoy art and be able

to make more of it for others, then people will live better and enjoy more.
