   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.
   The report says【C16】______Mars probably had a warmer climate in ages【C17】______due to its axis having been more steeply tilted towards the Sun.

【C7】
选项 A、tidings
B、news
C、intelligence
D、information
答案D
解析 名词辨析。由于and连接的是并列结构，所以此处应该填入一个与picture对应的能够用scientific修饰的词，所以答案是information，scientific information表示“科技信息”。intelligence多指市场信息和军事情报。
