[单项选择]Bill Gates seems to relish being the skunk at the garden party. The former boss of Microsoft, now a global-health philanthropist, was invited to address a big "m-health" conference in Washington, D. C. Some 2,400 proponents of delivering health services over wireless telecoms, from the private and public sectors, gathered to celebrate the dozens of pilot projects under way around the world.
