________ excited Geoff Marcy most was whether there were planets in other solar system where life might exist.   
A．ItB．ThatC．What D．Why
C

試題分析：句意：使Geoff Marcy高興的是，是否在太陽系的其他的行星上有生命存在。這里缺少主語從句的連詞，并且連詞在從句中做主語，排除ABD，that在從句中不做成分，why不能做主語。故選C。
點評：本題難度適中。判斷從句中用哪個連詞，需用記住連詞的用法，在句中的作用，連詞也是高考的熱點，需要考生平時多練習。需要考生會分析句子成分理解句意。
即學即練：That is______I am not in favour of the plan.
A. It             B. That           C. What            D. Why
解析：D。句意：那是我不贊成這個計劃的理由。
