问题
W: Today’ s guest on "Science Update" is David Brown. Dr. Brown, you and your team have found bacteria far below the Earth’ s surface. You must be thrilled about your discovery.
M: Well, yes, it’ s very exciting. For a long time, we’ d suspected the presence of such organisms, but we lacked substantial evidence.
W: How did you confirm the existence of the bacteria?
M: Well, technology helped. Our drilling techniques have improved significantly, and so the risk that surface bacteria could be mistaken for those found at much greater depth was reduced. With the new techniques, we could get much deeper into the Earth.
W: How far down did you actually get?
M: In one case, about three kilometers. We were surprised, I must tell you, that there were organisms that far down.
W: You know, it sounds like fiction, something like a lost world.
M: Let’ s call it a hidden biosphere, and it’ s probably a very extensive one. The mass of the living organisms below the surface may be equal in size to the mass of the surface bacteria.
W: Have you found any unique life-forms?
M: Yes. One of the organisms is the first anaerobic bacillus ever discovered. That means it can live and grow only where there is no oxygen.
W: Is there any danger of these bacteria infecting people when you bring them to the surface?
M: The bacteria in question were adapted to an environment that’ s hostile and alien to humans. Conversely, these anaerobic bacteria could not survive in our environment. So we really don’ t need to worry about these bacteria causing illnesses in people.
选项
A、Its texture.
B、lts size.
C、Its preservation.
D、Its shape.
答案
B
解析
在答长对话听力题时,考生最好能够先浏览一遍问题,这样可以做到有的放矢。例如,在这道题里,考生如果能够先浏览问题,在听时格外留意“hidden biosphere”(隐藏的生物圈)的出现,就不难发现M讨论的足这个生物圈的广阔性。
