研究：废寝忘食并不能有效提高成绩

Sacrificing sleep and skipping meals to study in quest for academic excellence actually doesn't work, a new Harvard study into 'grit' has revealed.
哈佛大学一项关于“决心”的研究表明，“废寝忘食”并不能奏效。

Children who strive for excellence tend to be seen as those who make extra sacrifices, like getting less sleep or adopting poor eating habits, in a search for top grades.
人们认为，争取优秀的孩子为了追求高分，一般都要做出额外牺牲，比如睡得少，或者养成糟糕的饮食习惯。

But the new study of 4,000 British teenagers shows those who display determination, courage and persistence also tend to have healthier lifestyles.
但是一项针对4000名英国中学生的新研究表明，那些展现出决心、勇气和坚持的学生一般会有更加健康的生活方式。

The findings, from Harvard Graduate School of Education, showed "that children who exhibit grit are also likely to look after themselves, and cultivate healthy emotional regulation skills, rather than behaving in ways that are bad for their health".
哈佛大学教育研究生院的研究结果表明，“那些有决心的孩子更可能照顾好自己，培养健康的情感管理技能，而不是养成不利于健康的行为方式。”

Studies have shown the harmful effects stress over exams have on children's health. A survey by Kellogg's published last month found that children as young as 10 smoke cigarettes, eat sweets and use energy drinks to prepare for their exams.
之前已有研究表明，考试压力过大对儿童的健康不利。凯洛格上个月发表的一项调查发现，年仅10岁的孩子就通过吸烟、吃糖果、喝能量饮料来备考。

Dr Christina Hinton, a faculty member at the Harvard Graduate School of Education, said: "Our results suggest that grit does not require pushing yourself at all costs, but rather cultivating healthy emotional regulation skills and effective learning strategies."
哈佛大学教育研究生院的教员克里斯提娜·辛顿说：“研究结果表明，追求好成绩的决心并不需要不惜一切代价来逼自己，而是要培养健康的情感管理技能和高效的学习策略。”
