Before the war broke out,many people____in safe places possessions they could not take with them.
A.threw away B.put away C.gave away D.carried away
选B,put away是收拾起来为以后使用,threw away是扔掉,give away是分发,carry away 拿走,（水）冲走,都不合适.另外要给你解释的是in safe places 是地点状语,put away的宾语是possessions,they could not take with them是定语从句修饰possessions.由于宾语带了定语从句结构太长,把状语in safe places提在了宾语的前面.
