Question

【题目】_____ his conclusion on the evidence he collected on the spot, he proved that the murderer was guilty.

A.BasedB.BasingC.To baseD.Being based

Answer 1

【答案】B

【解析】

考查非谓语动词。句意：根据他当场搜集的证据得出的结论，证明凶手是有罪的。base…on意为“以……为依据”，base的逻辑主语是句子的主语he，它们之间存在主动关系，所以应该用base的现在分词形式basing，在句子中做方式状语。故选B项。
