  In the passage, the author is primarily concerned with

  A.searching for an accurate method of dating the Pleistocene epoch

  B.discussing problems involved in providing an accurate picture of the Pleistocene epoch

  C.declaring opposition to the use of the term "Ice Age" for the Pleistocene epoch

  D.criticizing fanciful schemes about what happened in the Pleistocene epoch

  E.refuting the idea that there is no way to tell if we are now living in an Ice Age

  The "wrong impression" (lines 1-2) to which the author refers is the idea that the

  A.climate of the Pleistocene epoch was not very different from the climate we are now experiencing

  B.climate of the Pleistocene epoch was composed of periods of violent storms

  C.Pleistocene epoch consisted of very wet, cold periods mixed with very dry, hot periods

  D.Pleistocene epoch comprised one period of continuous glaciation during which Northern Europe was covered with ice sheets

  E.Pleistocene epoch has no long periods during which much of the Earth was covered by ice

  According to the passage, one of the reasons for the deficiencies of the "early classification of Alpine glaciation" (lines 45-46) is that it was

  A.derived from evidence that was only tangentially related to times of actual glaciation

  B.based primarily on fossil remains rather than on actual living organisms

  C.an abstract, imaginative scheme of how the period might have been structured

  D.based on unmethodical examinations of randomly chosen glacial biological remains

  E.derived from evidence that had been haphazardly gathered from glacial deposits and inaccurately evaluated

  Which of the following does the passage imply about the "early classification of Alpine glaciation" (lines 45-46)?

  A.It should not have been applied as widely as it was.

  B.It represents the best possible scientific practice, given the tools available at the time.

  C.It was a valuable tool, in its time, for measuring the length of the four periods of glaciation.

  D.It could be useful, but only as a general guide to the events of the Pleistocene epoch.

  E.It does not shed any light on the methods used at the time for investigating periods of glaciation.

  It can be inferred from the passage that an important result of producing an accurate chronology of events of the Pleistocene epoch would be a

  A.clearer idea of the origin of the Earth

  B.clearer picture of the Earth during the time that humans developed

  C.clearer understanding of the reasons for the existence of deserts

  D.more detailed understanding of how radioactive dating of minerals works

  E.firmer understanding of how the northern polar ice cap developed

  The author refers to deserts primarily in order to

  A.illustrate the idea that an interglacial climate is marked by oscillations of wet and dry periods

  B.illustrate the idea that what happened in the deserts during the Ice Age had far-reaching effects even on the ice sheets of Central and Northern Europe

  C.illustrate the idea that the effects of the Ice Age's climatic variations extended beyond the areas of ice

  D.support the view that during the Ice Age sheets of ice covered some of the deserts of the world

  E.support the view that we are probably living in a postglacial period

  The author would regard the idea that we are living in an interglacial period as

  A.unimportant

  B.unscientific

  C.self-evident

  D.plausible

  E.absurd

  正确答案:B D A A B C D
