Question

Mrs Green are very grateful to the neighbour _____ helped her child out of the fire．

A．which

B．what

C．who

D．how

Answer 1

C

試題分析：根據語境可知此句的先行詞是the neighbor是人，且在從句中做主語故選who，故選C。
點評：定語從句的引導詞有關系代詞who， whom，whose，which，that， as；關系副詞when， where，why。定語從句中引導詞的選用主要看先行詞在定語從句中作什么成分或者是定語從句中缺什么成分。
