好，如果导数很小的话，函数就基本没什么变化，可能我们就想把步子迈大一点儿了，但是别为这个担心？

All right. If the derivative is small, it's not changing, maybe want to take a larger step, but let's not worry about that all right?

当今世界，经济形势和工作环境都急剧变化，许多年纪稍大一点的人越来越担心受到淘汰。

A growing fear that many older people have in our rapidly changing economic and work environment is that of being viewed as obsolete before their time.

One way to think about this intuitively if the derivative is very large the function is changing quickly, and therefore we want to take small steps.

关于这个方法很直观的一点想法是,如果导数非常大,函数也就变化的非常快，因此我们想一小步一小步的来。
