问题     Are we at the beginning of another Age of Exploration? Perhaps even more important, are we at the beginning of【C1】______Age of Colonization? As the population of the world increases towards the point【C2】______the earth can no longer support all the people【C3】______on it, the second question becomes urgent. Will we discover a new world, 【C4】______Columbus did, on which human life will be possible? At this point in the space age, no one can really answer these questions. We can say, 【C5】______that we will not see tomorrow the kind of space travel that【C6】______fiction and the movies have shown. It will be a long time before we have flight that run【C7】______to human colonies on the moon or on, one of the planets. We are not even going to be able to【C8】______immediate advantages of the minerals that we may find on the planets【C9】______our own solar system.
    Great problems must be solved【C10】______we could send colonists out into place.

选项 A、ethical
B、science
C、affectional
D、action
答案 B
解析 词义辨析。通过后面的and the movies have shown，可推测要填入的词应和fiction构成另一个主语。再根据先行词space travel判定，此处明显应是“科幻小说”。故答案为B。选项中，sciencefiction意为“科幻小说”，符合要求。ethical fiction“伦理小说”；affectional fiction“言情小说”；action fiction“武打小说”。
