问题 The final quarter of the nineteenth century marked a turning point in the history of biology—biologists became less interested in applying an ideal of historical explanation deductively to organic function and more interested in discerning the causes of vital processes through experimental manipulation. But it is impossible to discuss the history of biology in the nineteenth century without emphasizing that those areas of biology most in the public eye had dependend on historical explanation. Wherever it was applied, historical explanation was deemed causal explanation The biologist-as-historian and the general historian of human events dealt with comparable phenomena and assumed necessarily a common mode of explanation
    Nineteenth-century biologists found a historical explanation of organic function attractive partly because their observation of the formation of a new cell from a preexisting cell seemed to confirm a historical explanation of cell generation. The same direct observation of continuous stages of development was also possible when they examined the complex sequence of events of embryogenesis. In both cases, the observer received a concrete impression that the daughter cell was brought into being, or caused, by the prior cell. The argument that these scientists employed confuses temporal succession and causal explanation, of course, but such confusion is the heart of most historical explanation.
    Not surprisingly, the evolutionary biologists of the nineteenth century encountered a particularly troublesome problem in their attempts to document historical explanation convincingly: the factual record of the history of life on earth (e. g. , that provided by fossils) was incomplete. The temporal continuity of living forms was convincing, but was an assumption that was difficult to uphold when one compared species or organisms forming any two stages of the evolutionary record. Nineteenth-century biologists recognized this problem and attempted to resolve it. Their solution today appears to be only verbal, but was then regarded as eminently causal. The fact of evolution demanded some connection between all reproducing individuals and the species that they compose, as well as between living species and their extinct ancestors. Their solution, the concept of heredity, seemed to fill in an admittedly deficient historical record and seemed to complete the argument for a historical explanation of evolutionary events.  [br] According to information presented in the passage, which of the following is a true statement about the methods of explanation used by biologists and historians in the nineteenth century?

选项 A、Neither biologists nor historians were able to develop methods of explanation that were accepted by the majority of their colleagues.
B、The methods used by biologists to explain phenomena changed dramatically, whereas the methods used by historians to explain events did not change as noticeably.
C、Biologists believed that they had refined the methods of explanation used by historians.
D、Biologists’ and historians’ methods of explaining what they believed to be comparable phenomena were similar.
E、Although biologists and historians adopted similar methods of explanation, the biologists were more apologetic about their use of these methods.

答案 D

解析 The passage states The biologist-as-historian and the general historian of human events dealt with comparable phenomena and assumed necessarily a common mode of explanation. This indicates, in other words, that biologists’ and historians’ methods were similar in explaining what they believed to be comparable phenomena.
A    The passage suggests that biologists through most of the nineteenth century tended to use historical explanation. Presumably, it is not true that biologists were unable to develop methods that were accepted by the majority of their colleagues.
B    The passage suggests that methods used by biologists changed significantly toward the end of the nineteenth century. However, nothing in the passage indicates to what extent, if at all, historians’ methods changed.
C    The passage suggests that biologists believed that, in observing embryogenesis and cell formation, there existed a clear justification for the utility of historical explanation in biology. However, there is no indication that these biologists believed that they had refined the historical methods used by historians.
D    Correct. The final sentence of the first paragraph indicates that the methods of biologists and historians in the nineteenth century were similar.
E    The only evidence that biologists were apologetic about their methods in the nineteenth century is that a turning point in their methods existed toward the end of the century. This is of course only weak evidence that biologists were apologetic. And even if these biologists were apologetic, nothing in the passage indicates whether historians were more or less apologetic.
The correct answer is D.
