China DailyLiquid water 'lake' revealed on Mars 科学家在火星上发现液态水体 Play audio file 研究人员们发现了火星上存在液态水体的证据。这片被科学家认作是湖的水体位于该行星南极的冰盖底部,横跨约二十公里(十二英里)。 文字稿 Since Nasa's Viking Mission tested Martian soil samples back in the 1970s, we've known the surface of Mars to be a desert – inhospitable to life as we know it. 自美国航空航天局(Nasa)在1970年代检测了由维京号计划从火星带回的土壤以来,火星表面一片荒芜且不适于生命生存这一道理就已为人熟知。但当火星勘探任务重点转向地表之下的时候,就有另一番景象开始浮出水面。 This discovery of water beneath the planet's South Pole is the result of radar echoes that were picked up by an instrument on a spacecraft that's been orbiting Mars for 15 years. To stay liquid beneath the long-frozen surface of Mars, the researchers say this sub-glacial lake must have huge amounts of salts dissolved in it. 词汇表 Martian 火星的 desert 荒漠 inhospitable 条件恶劣的,不适合生存的 emerge (真相)显露、浮现 radar echoes 雷达回波 instrument 仪器 sub-glacial 冰川下的 harsh (环境)严酷的 organisms 有机体 robot 机器人 encapsulating 压住、盖住 the Red Planet “红色星球”,指火星 2.
