来看一下在我们方法论课中讲到的两道题目 1. national bank retains this potency partly because its control of the nation’s banking system is (i)___governmental interference. A. unencumbered by B. replete with C. hindered by 在这道题目中，potency (有力)对于政府部分来说是好事，governmental interference (政府干预)是一件坏事； 并且governmental interference对于政府部门来说是一件坏事，所以应该选择unencumbered 2. The science of astronomy was begun by amateurs and today remains dependent on their contributions, which are incisive by virtue of being___by the a priori assumptions that often vitiate the work of professional research scientists. A.characterized B.unencumbered C.supported D.contradicted E.inspired 在这道题目中, contributions, which are incisive (深远的贡献)是一件好事, vitiate the work(使工作无效=毫无贡献)是一件坏事； 并且priori assumptions根据后面的从句可知，不是一件好事，所以空格选择unencumbered。 |
