家有儿童,给他们的鞋子系鞋带是件极其麻烦的事,家有行动不便的老人,他们穿鞋系带也有同样的苦恼。1948年之前,人们一直被这样一个不大不小的难题困扰着。瑞士一个叫乔治的人就想帮助人们解决这个问题。他一直在苦苦思索,希望能找到一种为行动不便的老人和小孩系鞋带的简便方法。
It is extremely troublesome for families to have children and shoelaces for their shoes. The elderly with mobility problems have the same distress as their shoes. Before 1948, people had been plagued by such a small problem. A Swiss man called George wanted to help people solve the problem. He had been thinking hard and hoping to find a simple way to tie shoes for the elderly and children with mobility problems.
