| ________ excited Geoff Marcy most was whether there were planets in other solar system where life might exist. |
答案
| C |
解析
试题分析：句意：使Geoff Marcy高兴的是，是否在太阳系的其他的行星上有生命存在。这里缺少主语从句的连词，并且连词在从句中做主语，排除ABD，that在从句中不做成分，why不能做主语。故选C。
点评：本题难度适中。判断从句中用哪个连词，需用记住连词的用法，在句中的作用，连词也是高考的热点，需要考生平时多练习。需要考生会分析句子成分理解句意。
