On a planet free of plate tectonics such as Mars,however, this water would remain trapped.Understanding how and when Mars lost its water is therefore crucial to knowing if life could have existed there and for how long. "The persistence of surface water could be highly relevant to the ...
“large amounts of”:更常用于宾语位置,突出分散或多样化的量。例如: Scientists have discovered large amounts of ice on Mars.(科学家在火星上发现了大量冰。) The report analysed large amounts of data.(报告分析了大量数据。) 三、语义侧重点的区别 “...
s ocean would depend on a steady supply of the amino acid from the surface, through the thick icy shell. Previous work by the same team had shown that meteorites impacting the ice could leave behind “melt pools” of liquid water, which then sink through the ice and deliver surface ...
What's so wild about this wet discovery?It could mean that the Red Planet once had enough water to have liquid flowing on the planet's surface. It was once believed that if Mars ever had water at all,its water would have been small amounts of ice below the surface or existing in the...

根据第三段的“It was once believed that if Mars ever had water at all, its water would have been small amounts of ice below the surface or existing in the soil only as hydrogen and oxygen(曾经有人认为,如果火星上有水的话,它的水可能是地表下的少量冰,或者只以氢和氧的形式存在于土壤中)...
The finding is exciting because microbial life is an important source of methane on Earth. However, methane can also be created through interactions between rocks and water, according to the mission team. Curiosity does not have instruments that can definitively say what the source of the methane...
B.there is a large amount of water at the polesC.the Mars may be able to support life in the futureD.conditions may have been similar to those on the Earth答案D解析:第一段大意是:人们最初对火星的印象是火星上不可能有生命。因为几乎没有氧气和水,并且夜间温度低于-...
