Question

【題目】_____ 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】

考查非謂語動詞。句意：根據(jù)他當(dāng)場搜集的證據(jù)得出的結(jié)論，證明兇手是有罪的。base…on意為“以……為依據(jù)”，base的邏輯主語是句子的主語he，它們之間存在主動關(guān)系，所以應(yīng)該用base的現(xiàn)在分詞形式basing，在句子中做方式狀語。故選B項(xiàng)。
