孩童时，我的爱好多的数不清，收集过硬币、邮票、贝壳、小石头、大理石、棒球明星的卡片，还有军功章。

As a child, I had numerous hobbies. I collected COINS, stamps, shells, rocks, marbles, baseball CARDS, and campaign buttons.

人们常认为大理石是一种石头，其实大理石是石化的钙(和古老的贝壳差不多)。

You probably think of marble as stone, but it is really petrified calcium (also known as old seashells).
