问题     Bill Gates believes the world needs better toilets. Specifically, toilets that improve hygiene, don’t have to connect to sewage systems at all and can break down human waste into fertilizer.
    So on Tuesday in Beijing, Mr. Gates held the Reinvented Toilet Expo, a chance for companies to showcase their takes on the simple bathroom fixture. Companies showed toilets that could separate urine from other waste for more efficient treatment, that recycled water for hand washing and that sported solar roofs.
    It’s no laughing matter. About 4.5 billion people — more than half the world’s population — live without access to safe sanitation. Globally, Mr. Gates told attendees, unsafe sanitation costs an estimated $223 billion a year in the form of higher health costs and lost productivity and wages.
    The reinvented toilets on display are a culmination of seven years of research and $200 million given by the Bill and Melinda Gates Foundation, which the former software tycoon runs with his wife, since 2011. On Tuesday, Mr. Gates pledged to give $200 million more in an effort get companies to see human waste as a big business.
    Mr. Gates said in an interview that "it will be at least a decade" before the reinvented toilets reach tens of millions of people in the poorest areas, and they will have to prove both practical and economical. "Nobody wants overnight solutions" in sanitation, he added.
    Though the products on display on Tuesday were nowhere as flashy, Mr. Gates has drawn criticism for giving thousands of dollars to universities in developed countries to create high-tech toilets that will take years to pay off— if they ever do.
    "Sometimes doubling down is necessary but you’ve got to be reflective, " said Jason Kass, the founder of Toilets for People, a Vermont-based social business that provides off-grid toilets. "Has any of the approaches done in the last five years created any sustainable lasting, positive impact vis a vis sanitation? And the answer, as far as I can see, is no. It might be a thing like the space program where people have fantasies about colonizing the moon and Mars, but it’s really not that practical, " he said.
    Mr. Gates acknowledged that some reinvented toilets, in small volumes, could cost as much as $10, 000, but added, "That will pretty quickly come down. The hard part will be getting it from $2, 000 to $500. I’d say we are more confident today that it was a good bet than where we started, but we are still not there."
    The Gates Foundation said the World Bank, the Asian Development Bank and the African Development Bank would commit $2.5 billion in financing for sanitation projects that provide people in all parts of a city — including the poorest neighborhoods — with safely managed sanitation services.
    "We see ourselves on the cusp of a sanitation revolution, " Mr. Gates told expo attendees on Tuesday.
    At a showroom in an art center in Beijing, companies including China’s Clear, Ecosan and CRRC, Sedron Technologies of the United States, India’s Eram Scientific and Switzerland’s Blue Diversion Autarky displayed toilets that could separate urine and recycle water for hand washing.
    During his opening remarks, Mr. Gates said he started getting interested in sanitation after he stopped working full time at Microsoft and began traveling more frequently to poor countries with his wife, Melinda.
    Holding up a beaker of fecal matter, Mr. Gates reminded the audience that human waste is disgusting, containing 200 trillion rotavirus cells and 100, 000 parasitic worm eggs, among other bacteria.
    Mr. Gates’s efforts to bring the discussion of toilets into the mainstream have legitimized a topic that many have avoided talking about for decades, said Jack Sim, the founder of the World Toilet Organization, a Singapore-based nonprofit organization committed to improving toilet and sanitation conditions worldwide. "The subject of toilets has been a neglected subject for some time, " said Mr. Sim. "The Gates Foundation is part of this momentum of breaking the taboo." [br] Which of the following statements is TRUE?
选项 A、The reinvented toilets will be used in some underdevelopment countries.
B、Bill Gates may spend $400 million in his better toilet plan.
C、The World Toilet Organization is an India-based nonprofit organization committed to improving toilet and sanitation conditions worldwide.
D、The discussion of toilets is a mainstream topic for decades.
答案 B
解析 文中第9段提到为城市的所有地区——包括最贫穷的居民区——提供安全周到的卫生服务，所以A选项不正确；最后一段提到世界厕所组织是设在新加坡的非营利组织，其致力于改善全球的厕所和卫生条件，所以C不正确；最后一段提到相当一段时间以来，厕所一直是个被忽视的议题，所以D不正确；文中第4段提到已投资2亿，计划再投资2亿，所以B正确。
