问题    Mars is not, it seems, the dry old planet we once believed it to be. Astronauts who are【C1】______to go there in the next decade may find plenty【C2】______water to slake(消除)their thirst.
   And with water present the【C3】______of finding some sort of life on Mars are【C4】______brighter.
   This is the view of 40【C5】______all over the world who have been analyzing【C6】______of pictures and other scientific【C7】______obtained by robot explorers in the sixties and seventies.
   To begin with, scientists thought the Red Planet was as【C8】______as the Moon with dust storms swirling over vast sandy【C9】______. But now the picture is very different with mountains and valleys carved by【C10】______glaciers and torrential rivers rushing and rumbling deep underground.
   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.
【C18】______convincing signs of plant or animal life have been【C19】______by instruments soft. landed on Mars,【C20】______only the immediate vicinity of landing vehicles could be examined.  
【C11】
选项 A、diagnosis
B、syntheses
C、analysis
D、analyses
答案C
解析 名词辨析，结合选项和句意分析，空格处应该填入一个名词，并且该名词的动词形式能够与the Martian pictures搭配，故而可以首先排除diagnosis (诊断)。systheses(综合)是指将不同的事物或观点合在一起，使之成为一个新的整体，与文意不符，故也可以排除。此处只能选analysis(分析)。
