单选题 The spaceman found ______ to look at the earth failing rapidly away from him.
A. a most exciting experience B. that a most exciting experience
C. the experience most exciting D. it a most exciting experience

【正确答案】 D

【答案解析】[解析] 动词find后面可以跟复合结构。在本句中，find的真正宾语为不定式to look at...，宾语补语为a most exciting experience。在复合结构中作宾语的如果是不定式的话，不定式应后移至句末，由形式宾语it填补。
