[填空题]
AIDS has killed 22 million people and it spreads with frightening speed. No known cure exists, yet we do learn some lessons in our battle against it:
Firstly, speak to your community, in a way they can hear. Many communities have a low literacy rate, making it impossible for passing out AIDS literature and expecting people to read it. To solve this problem, ask people in the community to create low-literacy AIDS education publications. Secondly, train teenagers to educate their peers. Because AIDS is spreading fastest among teenagers, the program trains youth to go into the community and explain the risk of catching AIDS to friends at their own age. At last, redefine "at risk" to include women from different backgrounds and marriage status. According to the Centers for Disease Control, women will soon make up 80 percent of those diagnosed (诊断)with HIV (艾滋病病毒).
These lessons are not the only solutions to the crisis but until there is a cure for AIDS, educ
