【题目】Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
Standing desks have been praised for their positive effects on physical health, reducing sitting time and lowering certain health risks linked to a sedentary( 久坐的) lifestyle. But could standing desks have positive mental effects?
New research suggests that students may think best when they are on their feet. It offers some of the first evidence of mental benefits of standing desks in classrooms.
Testing was done on high school freshmen who used standing desks, evaluating them at the beginning and end of the school year. Dr. Ranjana Mehta, an assistant professor at the Texas A&M School of Public Health, led the experiments aiming to assess standing desks’ mental benefits.
Through computerized tests, students’ executive functions were evaluated. Executive functions are the cognitive skills used to analyze tasks and break them into steps, and are directly related to academic needs like time management, memorizing facts and solving multi-step problems. These functions are largely controlled by frontal(前额的) brain regions, so researchers used a portable brain-imaging device to examine any related changes.
“Test results indicated that continued use of standing desks was associated with significant improvements in executive functions and working memory abilities,” Mehta said. “Changes in corresponding brain activation patterns were also observed.”
“Interestingly, our research showed the use of standing desks improved mental function, which is consistent with results from previous studies on school-based exercise programs,” Mehta noted.
Policymakers, public health professionals and school administrators should consider the positive effects of standing desks and make some simple changes in classrooms that will have the potential to increase energy expenditure and develop cognitive skills. That would be a valuable contribution to the educational world.
【答案】Standing desks have positive effects on physical health. Now new research offers evidence that standing desks offers mental benefits too. Experiments on high school students showed standing desks improved students’ executive function and memory/cognitive ability and problem solving skills. These effects are similar to the effects of exercise. Standing desks should be used in classrooms to burn more energy and improve cognitive skills.
【解析】
这是一篇概要写作。短文介绍了站立式书桌对身体健康的积极影响。
概要写作需要先理清文章主题和篇章结构,在此基础上再加以总结。可以先梳理各段的内容:
第一段:提出站立式书桌对人的健康有好处,而在最后话锋一转,引出文章中心论点:站立式书桌对于精神方面的影响。这一部分可以总结为:Standing desks have positive effects on physical health. Now new research offers evidence that standing desks offers mental benefits too.
第二、三、四段:详述一项针对前面论点的新研究的过程,通过观察比较对照组高中学生学期始末的成绩来评估学生大脑的执行功能。
第五、六段:引述研究主导人Metha的话,得出结论:长期使用站立式书桌使得执行功能、工作记忆能力等都有所提升,即确实能提高学生心智,与先前的研究结果是一致的。这两部分可以总结为:Experiments on high school students showed standing desks improved students’ executive function and memory/cognitive ability and problem solving skills.
第七段:作者根据前面得出的结论向决策者、学校管理者和健康专家们提出建议。这一部分可以总结为:Standing desks should be used in classrooms to burn more energy and improve cognitive skills.
这样就可以较为全面、清晰地写出全文概要了。
