摘要：( A ) A picture, a calendar or even a balloon may be the best way for millions of people living in China’s vast country areas to learn about AIDS, one of the biggest threats to public health in the world today. China has decided to use user-friendly methods including exhibitions, VCD and TV programmes to spread knowledge of the disease across the nation to try to keep it in check. Educating people nationwide about AIDS is the top priority to prevent the disease from getting out of hand. The farmers will be given knowledge in the easiest way that they can understand. A recent survey from the commission of more than 7,000people in China showed that nearly 20 percent of them had never heard of AIDS before. Just over 71percent said they knew AIDS was highly infectious, but most of them had no clear idea of how the disease could be spread. Just over 62 percent said they knew that they could do things in advance to prevent themselves catching AIDS but they didn’t know what these measures were. The month-long survey, carried out last December, talked to people in seven counties and cities across China including both developed coastal areas and the less-developed inland areas. The interviewees ranged from 15 to 49 years old, and country residents were about 63% of the total surveyed. Chinese residents, especially those in the country, have very little knowledge about what AIDS is all about, not to mention prevention and treatment. By the end of last year, there were 22,517 known HIV/AIDS cases in China. However, more than 6,000,000 people in China have been infected. Since 1985, China has discovered 880 patients with AIDS --- 466 of them have died. Sharing needles, prostitution and contaminated blood transfusions are major ways for HIV to spread. A lack of education has been the biggest difficulty against nationwide efforts to prevent AIDS, especially in the countryside. 56.According to the passage, we can know that . A.
