问题     Physical activity does the body good, and there’s growing evidence that it helps the brain too. Researchers in the Netherlands report that children who get more exercise, whether at school or on their own,【C1】________to have higher GPAs and better scores on standardized tests. 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.

    C) current            H) flow          M) review

选项
答案F
解析 空格前面是系动词are，后面为介宾结构to learning，因此空格处需要填入形容词，且与介词to搭配。本句中提到体育锻炼可以改善大脑的血液循环，从而提高记忆力、注意力和创造力。因此，空格处需要填入一个表示褒义的形容词，表明这些能力对学习的重要性。备选形容词中，essential“必不可少的”符合句意，故为答案。
