答案                             AIDS
    When AIDS first emerged, / no one could have predicted how the epidemic would spread across the world / and how many millions of lives it would change. / There was no real idea what caused it / and consequently no real idea how to protect against it. / Now we know from bitter experience / that AIDS is caused by the virus HIV, / and that it can destroy families, communities and whole continents. / However, experience has also shown us that the right approaches can and do result in lower national HIV infection rates / and less suffering for those affected by the epidemic. / Already, more than twenty-five million people around the world have died of AIDS-related diseases. / 33 million people around the world are now living with HIV, / and most of these are likely to die over the next decade or so. / It is disappointing that the global numbers of people infected with HIV continue to rise, / despite the fact that effective prevention strategies already exist.
