Day490-新兴火车时代的来临

零排放新型火车到来了The world's first hydrogen-powered train has been rolled out in Germany on Monday. Two bright blue trains replace the old diesel trains. The technology has realized zero-emissions since the fuel cells on the train produce electricity through a combination of hydrogen and oxygen, which will only leave steam and water after the process. The debut of the hydrogen-powered train marks a breakthrough toward eco-friendly development.本周一世界上第一辆氢气动力火车在德国试行，两辆鲜艳蓝色的火车代替了旧的柴油火车。零排放技术已经实现了，火车上的燃料电池用氢气和氧气混合燃烧发电，经过作用只会产生蒸气和水。氢气动力火车首次试行标志着环境友好型发展实现重大突破。Language Focus 语言聚焦 1.hydrogen /'haɪdrədʒən/ 氢；氢气2.oxygen/'ɑksɪdʒən/ 氧气3.hydrogen-powered氢动力的Eg. hydrogen-powered vehicle 氢气汽车Eg. hydrogen-powered train 氢气火车4.diesel /'diːz(ə)l/ 柴油Eg. diesel truck 以柴油为燃料的卡车Eg. diesel engine 柴油发动机5.zero-emission  /ɪ'mɪʃ(ə)n/ 零排放Eg. zero-emission vehicles零排放交通工具Eg. zero-emission homes 零排放住宅6.fuel cell燃料电池Eg. fuel cell technology 燃料电池技术Eg. fuel cell car 燃料电池汽车7.breakthrough/'breɪkθruː/ 突破；重大进展Eg. Make a breakthrough in…  在……方面取得重大进展8.eco-friendly /'i:kəu,frendli/ 环境友好型的，生态环境Eg. eco-friendly products 对环境无害的产品Eg. eco-friendly life 环保式生活
