In a report on the【C11】______of the Martian pictures Dr. Michael Car of the U.S. Geological Survey comments, "I am【C12】______there’s lots of water on Mars." Any surface water will be in the【C13】______of ice. But it could【C14】______explorers having to take so much fresh【C15】______with them.

选项
A、convinced
B、guaranteed
C、believed
D、proved

解析
动词辨析,I am convinced…意为“我被说服相信……”。guarantee意为“保证”,believe意为“相信”,一般不用于被动语态;proved不合题意,不能说“我被证明……”。
