问题 Following the new discovery, the scientists had finally precluded the doubts on the validity of the theory.

选项 A、cleared up
B、fired away
C、put aside
D、put together

答案A

解析 关注点:从动宾搭配甄别被替换词的词义。对于有些读者,被替换词preclude也许不很熟悉,这样一来,准确确定选项词也就有了障碍。尽管四个选项词都是大家熟悉的动词短语,但这种“熟悉”对答题者来说仍是无济于事,在这个时候,确定被替换词的词义就成了需要攻克的难关。那么,precluded到底有何解?看看题干状语“following the new discovery”,再仔细推敲一下“…doubts on the validity of the theory”,答案就不难确定了,因为能够与宾语相搭的谓语动词大都与“消除”或“排除”的意思相关。再看四个选项词,也只有A项的cleared up才能作为precluded的替换词。此案例给大家的启示是:当被替换词较为陌生时,利用对“动宾搭配”可能性的分析来确定被替换词的词义也不失为一种“出路”。
