本文从以下几个角度介绍。

DDeep below the ground,radioactive elements break up water molecules(),producingsubstances that can fuel subsurface life.This process,known as radiolysis（(辐射分解)，hassupported bacteria in tiny cracks filled with water on Earth for millions to billions of years.Now a study published in Astrobiology shows that radiolysis may have supported life in theMartian subsurface.Dust storms,rays in the universe and solar winds ruin the Red Planet's surface.But below,some life might find shelter."The best survival habitat on Mars is the subsurface,"said JesseTarnas,a planetary scientist at NASA.Examining the Martian underground could helpscientists learn whether life existed there.And the best subsurface samples available today areMartian meteorites()that have crash-landed on Earth.Tarnas and his colleague looked at the minerals on the Martian surface and how manyradioactiveelements there were,using satellite and rover data.They used computers tosimulate()radiolysis to see how efficiently the process would have generated life-supportinghydrogen gas and other chemical substances.They reported that if water was present,radiolysiscould have supported life for billions of years and perhaps still could today.Scientists had previously studied Mars radiolysis,but this marked the first estimate usingMartian rocks to see how habitable Mars underground might be.Tarnas and his colleagues alsoevaluated the potential richness of life in Martian underground.They found that up to a millionbacteria could exist.in just one kilogram of rock.The most habitable seemed to be the southernhighlands of Mars,which is the most ancient area on Mars,according to Tamas"Underground life would require water and it remains unknown if groundwater exists on theplanet,"says Lujendra Ojba,a planetary scientist at Rutgers University.Determining whetherthe Martian subsurface contains water will be an important next step,but this investigation.helps to motivate that search.Ojha says,"Where there is groundwater,there could be life."..32.What does radiolysis refer to according to the passage?A.The formation of water deep underground.10nn:6001B.The breakdown ofrocks in the Earth's core.C.The production of energy from radioactive elements.D.The process of radioactive elements splitting water molecule.33.How did Tarnas anid his colleague carry out their research?.A.By simulating with collected data.B.By comparing original data.C.By engaging in a Martian field research.D.By conducting a survey...34.Which can be inferred from the last 2 paragraphs?A.Tarnas is the first to study Mars radiolysis.B.The presence of groundwater is key to the findings.C.Ojha questions that underground life exists on Mars.D.The southern highlands of Mars was home to millions of bacteria.35.What is the research mainly about?A.The reason for no life on the Martian surface.B.The:data source for the study of Martian habitability.C.The possibility of Mars sustaining life through radiolysis.D.The richness of radioactive elements below the Martian surface.英语试卷第6页（共10页）
