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.

【C5】
选项
答案N
解析 动词辨析题。空格前面有介词to，后面有介词短语on smaller budgets，所以空格处应填入一个动词原形。另外，从句意上来看，这一句与上句为因果关系，说明出现关于废除体育课争论的原因，即：学校赖以生存的财政预算减少。备选动词中符合结构和句意双重要求的只有survive，由此确定N)为本题答案。备选项中的depressing和dropping都是分词形式，不能与to搭配构成动词不定式，可以排除。
