A study in Norway has found that students who stayed in school longer than others their age scored higher on intelligence tests.
挪威一项研究发现,同龄人中,上学时间更长的学生智力测验得分更高。
In the middle of the nineteen fifties, the government began requiring students to attend school until the age of sixteen instead of fourteen. Communities had almost twenty years to make the change. So some students went to school for seven years while others went for at least nine years.
在20世纪50年代中期,挪威政府开始要求学生16岁前必须上学,此前要求是14岁。公众做出此改变用了将近20年。所以当有些学生上了7年学时,另一些学生上了至少9年学。
