【推荐1】A recent study shows that more years of school could help students get higher scores on intelligence tests. That was the finding of a study of teenage males in Norway. Now, other research shows that_______activity may help students do better in their classes.

The research comes as educators in some countries are reducing time for activities like physical education. They are using the time instead for_________subjects like math and reading.

Researchers at VU University Medical Center in Amsterdam_______the results of fourteen studies, which included more than fifty-five thousand children, aged six to eighteen.

Research Amika Singh says the studies showed a _______between physical activity and scores on subjects such as Math, English and reading. “Based on the results of our study we can conclude that being physically active is_______for academic performance.”

Ms. Singh_________some possible explanations. “There are, first, physiological explanations, like more blood flow, and so more oxygen to the brain. Being physically_______means there are more hormones produced like endorphins（内啡肽）. And endorphins make your stress level lower and your mood improved, which means you also_______better.”

Also, students_______in organized sports learn rules and how to follow them. This could improve their classroom________and help them keep their mind on their work.

The study__________some questions unanswered, however. Ms. Singh says it is not possible to say whether the amounts or kind of activity________the level of academic improvement. This is because of differences among the studies.

Also, they were mostly observational studies. An observational study is where researchers do not do controlled comparisons. They only describe what they observe. So they might observe a link that students who are more active often have better grades. But that does not__________mean being active was the cause of those higher grades. Therefore, more high-quality studies are needed to ________their findings.

Still, the general finding was that physically active kids are more likely to do better in school. Ms. Singh says schools should consider that finding before they________physical education programs.
