In a【C2】________of 14 studies that looked at physical activity and academic【C3】________, investigators found that the more children moved, the better their grades were in school, 【C4】________in the basic subjects of math, English and reading.
    The data will certainly fuel the ongoing debate over whether physical education classes should be cut as schools struggle to【C5】________on smaller budgets. The arguments against physical education have included concerns that gym time may be taking away from study time. With standardized test scores in the U.S. 【C6】________in recent years, some administrators believe students need to spend more time in the classroom instead of on the playground. But as these findings show, exercise and academics may not be【C7】________exclusive. Physical activity can improve blood【C8】________       to the brain, fueling memory, attention and creativity, which are【C9】________        to learning. And exercise releases hormones that can improve【C10】________and relieve stress, which can also help learning. So while it may seem as if kids are just exercising their bodies, when they’re running around, they may actually be exercising their brains as well.

选项
答案E
解析 分析句子结构可知，空格在With引导独立主格结构中，由此可知空格处应填入分词。由句意可知，近年来美国学生的标准化考试成绩________，因此，一些行政官员认为学生们应该将更多的时间放在课堂上而不是操场上。由行政官员的看法可以推知，应该是学生考试成绩不如以前了，他们才会要求减少锻炼的时间。备选动词中，表示“下降，减少”意思的词只有dropping“降低，减少”，故为答案。
