The science of astronomy was begun by amateurs and today remains dependent on their contributions, which are incisive by virtue of being ------- by a prior assumption that often vitiate the work of professional research scientists.
查了一下,网上各种答案的版本。貌似选B的多一些。
我自己觉得BCE都讲的通啊。。。都可以说明因为削弱了专业人士的成果的‘prior assumption’,这样可以支持‘The science of astronomy was begun by amateurs and today remains dependent on their contributions’这种说法。
再标注下,这两个单词,当时没看懂。 a priori:using facts or principles that are known to be true in order to decide what the probable effects or results of sth will be, for example saying 'They haven't eaten anything all day so they must be hungry.' 从事实推断结果;由因及果;先验的
a posteriori:analysing sth by starting from known facts and then thinking about the possible causes of the facts, for example saying 'Look, the streets are wet so it must have been raining.' 从事实推断原因;由果及因;后验的
