单选题It is the education 

问题补充：

单选题Itistheeducation_________hereceivedwhenstudyingabroad_________hasmadehimsuchanexcellentmanager.A.that; thatB.which; whichC.that; whichD.where; that

答案：

A解析考查定语从句和强调句型。That指代先行词the education引导定语从句that he received when studying abroad，在句中做receive的宾语。第二空的that与it is构成强调句型的基本结构。句意：正是他在国外学习的时候所接受的教育让他成为了一名优秀的经理。故A正确。
