VOA英语学习,教育报告

Studies have shownthat children from poor families have more difficulty in school than other boysand girls. Children with higher socioeconomic roots seem better prepared andperform better on school tests.

研究表明,来自贫穷家庭的孩子在学校的表面更加困难。社会经济条件好一点的孩子,在学校考试中,似乎准备得更好,表现得更好。

Now, Americanresearchers may have found a biological reason for that difference. They founddifferences in the brains of students who had low standardizedtest scores. Theirbrains had less gray matter and their temporal lobes developed more slowly than the other children. The findings were reportedin the journal JAMA Pediatrics.

现在,美国的研究人员可能发现了这种区别的生理原因。他们在标准化考试得低分的学生大脑中发现了差别。他们的大脑中灰质和颞叶比其他孩子发展更慢。报告发表在JAMA Pediatrics.杂志上。

Temporal lobes andgray matter are very important brain areas, says researcher Barbara Wolfe. Sheis a professor of economics, population health and public affairs at the University of Wisconsinat Madison.

研究员Barbara Wolfe说,颞叶和灰质在大脑中非常重要。她是(位于麦迪逊的)威斯康星州立大学(University of Wisconsin)的教授,研究经济学,公共卫生和公共事务。

The brain areas are"critical in the sense that they keep developing until individuals arewell into their adolescence or early 20s, and critical in the sense that they are important forexecutive function," she said.

这片大脑区域,她说“直到青春期或者20岁出头,就某种程度上对生长发育非常关键,对执行能力也非常重要。

Researchers studiedbrain images of nearly 400 children and young adults. The youngest subjectswere four years old. The oldest were 22. Researchers looked for a connectionbetween the person’s socioeconomic status and his or her test results.

研究人员分析了400多孩子和年轻的成年人的大脑图象。最年轻的4岁,最大的22岁。他们寻找人的社会经济学地位和他(她)考试结果之间的关联。

On average, youngpeople from poor families had test scores between three and four points belowwhat is expected for their age group.

来自贫穷家庭的年轻人,测试分数比相同年龄组平均分数差3至4分。

The pooreststudents scored between eight and 10 points below the developmental norm. Ms.Wolfe says there are several reasons why poorer students often have lowerscores. One reason could be poor children do not get the food they need forhealthy development. Poor parents are less likely to stimulate their children’s brains through talk,play, and activities. Ms. Wolfe also blames the "stress that parents facein trying to deal with poverty, putting food on the table."

最贫穷的学生分差8到10分。Ms. Wolfe说,有多个原因解释贫穷学生经常考分较低。一是贫穷孩子吃不到健康发育需要的食物。贫穷家长可能很少通过谈话、游戏等活动去刺激孩子大脑。Ms. Wolfe还怪家长面对努力摆脱贫困的压力、在桌上放食物的方式。

The researchers saythat up to 20 percent of the achievement gap, or difference in test performance,could be tied to poverty.

研究人员说,成绩差距中,近20%与贫穷有关。

Ms. Wolfe suggestsearly action may improve the brain development of children living in poverty.Reaching out to children when they are very young could help raise their testscores and academic performance when they are older.

MS Wolfe提出,对于贫穷家庭生活的孩子,早期的干预行动可能改善大脑的发育。在他们年轻时,伸出援助之手,可以帮助提高他们长大后的考试分数和学术能力。

She says that whenthe source of the deficit is known, "these areas of the brain can bedeveloped," she said. "... It means that policies can be developedthat overcome this deficit."

她表明,当这种不足的根源发现后,“这片大脑是可能发育成熟的”“……..意谓着,可以形成弥补不足的政策”
