If you are like most people,your intelligence varies from season

If you are like most people,your intelligence varies from season to season．You are probably a lot sharper in the spring than you are at any other time of the year．A noted scientist,Ellsworth Huntington(1876-1947),concluded from other men's work and his own among peoples in different climates that climate and temperature have a definite effect on our mental abilities. He found that cool weather is much more favorable for creative thinking than is summer heat．This does not mean that all people are less intelligent in the summer than they are during the rest of the year．It does mean,however,that the mental abilities of large numbers of people tend to be lowest in the summer. Spring appears to be the best period of the year for thinking．One reason may be that in the spring man's mental abilities are affected by the same factors that bring about great changes in all nature. Fall is the next-best season,then winter．As for summer,it seems to be a good time to take a long vacation from thinking! It seems that the cold winter__.
A、increases the ability to think
B、is the best time for thinking
C、is better for thinking than is very warm weather
D、decreases the ability to think
【正确答案】：C
【题目解析】：根据文本内容，著名科学家 Ellsworth Huntington 通过研究不同气候地区的人们得出结论：气候和温度对我们的智力有一定影响，凉爽的天气比炎热的夏天更有利于创造性思维。虽然这并不意味着所有人在夏天都比其他季节笨，但确实意味着很多人在夏天的智力倾向于最低。 然后文章分别阐述了春天是思考的最佳时期，秋天次之，冬天再次之，而夏天似乎是一个适合长时间休假不思考的季节。 逐一分析选项： - A 项：文章未明确表示寒冷的冬天会“增强思考能力”，该项说法过于绝对，排除； - B 项：文章说春天是思考的最佳时期，而非冬天，排除； - C 项：文章明确指出“凉爽的天气比炎热的夏天更有利于创造性思维”，而寒冷的冬天比炎热的夏天温度更低，所以可以合理推出寒冷的冬天比非常温暖的天气更有利于思考，该项正确，当选； - D 项：文章未明确表示寒冷的冬天会“降低思考能力”，该项说法过于绝对，排除。 综上所述，正确答案是 C。
