Question

【題目】Plenty of exercise improves the academic performance (學(xué)習(xí)成績) of teenagers, according to new research.

The study, of about 5,000 children, found links between exercise and exam success in English, maths and science. It found an increase in performance for every extra 17 minutes exercise for boys, and 12 minutes for girls.

The study by the University of Strathclyde and the University of Dundee found physical activity particularly benefited girls’ performance in science. The authors said this could be a chance to find or reflect gender differences in the impact (影響) of physical activity on the brain.

Most of the teenagers’ exercise levels were found to be well below the recommended 60 minutes a day. The authors wondered what might happen to academic performance if children got the recommended amount.

They claimed that since every 15 minutes of exercise improved performance by an average of about a quarter of a grade, it was possible for children who carried out 60 minutes of exercise every day to improve their academic performance by a full letter grade — for example, from a C to a B, or a B to an A.

However, the authors admitted this was speculation given that very few children did this amount of exercise.

Dr. Josie Booth, one of the leaders of the study, from the University of Dundee said, “Physical activity is more than just important for your physical health. There are other benefits and those are something that should be especially important to parents, policymakers and people involved in education.”

The authors of the study, published in the British Journal of Sports Medicine, said further research backing the findings could have implications for public health and education policy.

Answer 1

【答案】

【1】B

【2】A

【3】B

【解析】一項新的研究結(jié)果表明，青少年鍛煉身體能夠提高學(xué)業(yè)成績。

【1】B主旨題。文章主要講述了體育鍛煉可以提高青少年的學(xué)業(yè)成績，也就是鍛煉和學(xué)業(yè)表現(xiàn)的關(guān)系，故選B。

【2】A詞義猜測題。根據(jù)第五段可知，研究者聲稱，既然孩子們每鍛煉15分鐘，成績平均可以提高大約四分之一，那么對他們來說，每天鍛煉一個小時，成績提高整整一個等級，即從C提高到B，從B提高到A是有可能的，這是研究真作出的一種推測。故選A。

【3】B推理判斷題。根據(jù)第七段的內(nèi)容可知，這項研究的領(lǐng)導(dǎo)者之一Dr. Josie Booth說，體育活動不僅僅有益于身體健康，還有其他好處。故選B。
