    It is our experiences that determine which colors we prefer,【C2】______a new study, which was the first to【C3】______ test the long-suspected idea that people like the colors of the things they like. In their【C4】______ to understand why people like certain colors, scientists have【C5】______on evolution. The main theory is that we like colors that are【C6】______ to things that are healthy and promote survival. A blue sky, for example, indicates calm weather, which【C7】______ explain why blue tends to be a (n)【C8】______ color across cultures. Dark yellows and oranges,【C9】______, invoke urine, vomit and rotting food.【C10】______expected, there is usually a drop in preference【C11】______ these colors in studies around the world.
  【C12】______ those general trends, there are wide-ranging differences among individuals about which colors they like. As part of a【C13】______of experiments, the researchers showed slide shows of colored objects to a group of【C14】______.

【C7】
选项 A、dare
B、must
C、might
D、need
答案C
解析 情态动词题。句意为：例如，蓝色的天空象征着风和日丽的天气，这也许可以解释为什么蓝色受到不同文化的人们的喜爱。由文章可知，有关颜色的研究仍处在初级阶段，所以这是一种猜测。选项中只有might和must表示猜测，而must的口气十分肯定，不符合上下文，所以排除。因此might“可能”为正确选项。dare“敢于”和need“(多用于疑问句和否定句)需要”与文意不符，故排除。
