把这一句，留给此刻的你
No use to shout at them to pay attention. If the situations, the materials, the problems before the child do not interest him, his attention will slip off to what does interest him, and no amount of exhortation of threats will bring it back.
没有必要为了集中注意力而对他们大喊大叫。如果孩子对眼前的情况、材料和问题不感兴趣，他的注意力就会转移到他感兴趣的事情上，再怎么威胁他也无济于事。
