英语翻译
Spending more than two hours a night doing homework leads to better results in English,math and science,according to a major study (by Pam Sammons,England) which has tracked (跟踪）the progress of 3,000 children over the past 15 years.
Spending any time doing homework showed advantages,but the influence was greater for the students who put in two to three hours a night,according to the study published by the Department for Education in England.
The scientists who did the research say their study emphasizes (强调）what students actually do rather than how much work the school has set.
Pam Sammons,a professor of education at Oxford University,said that time spent on homework showed the influence of the school—if children were expected to do homework and if
they enjoy their subjects.“That’s one of the reasons Indian and Chinese children do better.They put more time in it.” he added.
It’s also reported that students who enjoyed school got better results.“Schools could make sure children had a better experience by improving the school environment,making school work interesting and making children feel supported by teachers." Sammons said.
It is suggested that children aged 5 to 7 should be set one-hour homework a week,half an hour a night for 7 to 11-year-olds.Secondary schools were encouraged to set up two hours a night for 14 to 16-year-olds.
“ Headteachers should make their own homework policy,” the government says.

根据英国Pam Sammons对15年内3000儿童的进步跟踪专业研究,每晚做作业超过2小时,可在英语、数学、科学方面取得更好的成绩.
根据英国教育部出版的研究报告,无论花多长时间做作业都是有好处的,但一晚2-3小时会取得更好的效果.
作出研究的科学家在报告中强调,重要的是学生实际在做什么,而不是学校布置了什么.
Pam Sammons,是剑桥大学教育学教授,他说花在作业上的时间显示了学校的旷-如果是期望孩子 做作业,并且如果他们喜欢他们的课程.他补充道,“这就是为什么印度人与中国人做得更好的原因.他们花的时间更多.”
报导还指出,喜欢上学的学生成绩更好.“学校能够保证通过改善学校环境、寓教于乐、使孩子感受到老师的支持使孩子得到更好的体验.”
建议5-7岁的孩子每周布置1个半小时的作业,7-11岁每晚布置半小时的作业.14-16岁初中生鼓励布置每晚两小时的作业.
政府指出,“校长需制定学校家庭作业的原则.”
