Children with no shoes on do better at school than those with shoes on，a study suggests．

    For over 10 years，researchers from universities observed （观察） children in 100 schools from 25 countries．They found that classrooms were quieter when children took off their shoes．It provided a quieter environment where pupils were more willing to focus on study than those with shoes on．

    "Children are much more willing to sit on the floor and relax if they have no shoes on，"said professor Stephen Heppel，a lead researcher．

    "The last place a child would sit to read is an upright chair．And we've found that 95% of them really don't read on a chair at home，"Heppel added．"When they go on holidays，they read lying down．"Professor Heppel hopes to bring the"shoeless policy"to all U．K．schools．He says relaxing conditions at school make children feel as if they're at home．He believes all the teachers will be glad to adopt the habit．
