     There is a handsome boy. He has golden hair and a pair of big blue eyes. But he looks very sad. He is thin and weak because he suffers from AIDS.

     In healthy human bodies, the immune system(免疫系统) protects them from diseases. But when one gets the AIDS virus(病毒) in his/her body it attacks and destroys the immune system, and the body then is helpless against diseases. And the patient will die of this or that disease.

     But you don't have to worry too much about being with the boy. The AIDS virus can't live outside his body, and it can't travel through the air. You don't need to be afraid to touch him, either.

     Children with AIDS need help from other children. They need to have friends to play with. Let's try our best to do something for them.
