问题    Again, note the use of figurative language, in this case the simile of the drunkard.
    At night, schools of prey and predators are
   almost always spectacularly illuminated by the
      bioluminescence produced by the microscopic
Line and larger plankton. The reason for the ubiquitous
  (5) production of light by the microorganisms of the
       sea remains obscure, and suggested explanations
       are controversial. It has been suggested that light
       is a kind of inadvertent by-product of life in trans-
       parent organisms. It has also been hypothesized
(10) that the emission of light on disturbance is advan-
       tageous to the plankton in making the predators of
       the plankton conspicuous to their predators!
       Unquestionably, it does act this way. Indeed,
       some fisheries base the detection of their prey on
(15) the bioluminescence that the fish excite. It is
     difficult, however, to defend the thesis that this
     effect was the direct factor in the original devel-
     opment of bioluminescence, since the effect was
     of no advantage to the individual microorganism
(20) that first developed it. Perhaps the luminescence
     of a microorganism also discourages attack by
     light-avoiding predators and is of initial survival
     benefit to the individual. As it then becomes
     general in the population, the effect of revealing
(25) plankton predators to their predators would also
     become important. [br] The author mentions the activities of fisheries in order to provide an example of
选项 A、how ubiquitous the phenomenon of bioluminescence is coastally
B、how predators do make use of bioluminescence in locating their prey
C、how human intervention imperils bioluminescent microorganisms
D、how nocturnal fishing expeditions are becoming more and more widespread
E、how limited bioluminescence is as a source of light for human use
答案 B
解析
