我曾经在书上、电视里看过一些古人沙里淘金的故事。那时的人用很简单的器物就能淘出纯度很高的黄金来。我看了,心想:既然这么简单,那我为何不试试看呢?于是我叫来了爸爸,让他和我在院子里一起“淘金”。邻居家在装修,门口堆了一个很大的沙堆。我跑过去,问工匠要了一些沙子。我用奶奶平时过滤用的小铁丝网把沙里的大石子一一过滤出来,然后请爸爸把它们扔掉。 I once read the story of some ancient people in the book, on the television, and on the television. At that time, people can scrape out the high-purity gold with very simple objects. I read, I thought: Since so simple, then why do not I try it? So I called my father, let him and I in the yard together, “Gold Rush.” Neighbors in the decoration, the door piled a big pile of sand. I ran and asked the craftsman for some sand. I use my grandmother usually filter with small wire mesh to filter out the sand in the big stones one by one, and then dad throw them away.
