问题 ______ with air, a life jacket will keep a person afloat.

选项 A、It is filled
B、Fining
C、When fined
D、When filling it

答案 C

解析句子结构题。根据句中出现的逗号，说明逗号前面部分不可能是一个句子，因此可以排除A 。又因fill和a life jacket为动宾关系，此处应该用被动结构，排除B 和D ，故C 是正确答案。其完整形式为when it is filled with air，...。在时间、条件、让步等状语从句中，当从句主语和主句主语一致的时候，可以将从句的主语和be的变化形式省略。
