为了记录黄豆的生长过程，我从一堆豆子里面精心地挑选出了三颗饱满、滚圆的干黄豆作为种子。干黄豆摸起来硬硬的，表面很光滑，中间有一条短短的`线，好像它的小嘴巴一样。

我拿出一个玻璃杯，并在杯子里加入了半杯冷水。我把黄豆用自来水冲洗干净，然后把黄豆扔进了杯子里。黄豆就像小石子一样迅速地沉入了杯底。黄豆浸泡在水里没多久之后就发生了变化。它的表皮马上发泡起皱，不再那么光滑平整。短短几分钟以后，黄豆已经鼓涨起来了，就像一个喝足水的小胖子一样。又过了一会儿，黄豆又发生了变化。它比之前大了很多，也长了很多，表面那层透明的皮好像马上就要脱落一样。

黄豆在水里呆了一天一夜之后，身体膨胀了许多，愈发像个胖乎乎的小胖子。胖得就快撑破外面的那层“衣服”了。隔着那层外衣，隐隐约约可以看到里面的小嫩芽。我这才发现:原来那条短短的线就是黄豆的嫩芽所在。

今天让黄豆继续呆在水里，等嫩芽再长大一些，我再给黄豆搬家。

In order to record the growth process of soybeans, I carefully selected three plump and round dried soybeans as seeds from a pile of beans. Dried soybeans are hard to the touch and have a smooth surface with a short line in the middle, like its small mouth.

I took out a glass and added half a cup of cold water to it. I rinsed the soybeans with tap water, and then threw the soybeans into the cup. The soybeans sank to the bottom of the cup as quickly as pebbles. Soybeans changed soon after they were soaked in water. Its skin immediately foamed and wrinkled, and it was no longer so smooth and flat. In just a few minutes, the soybeans had swelled up, like a fat man drinking plenty of water. After a while, the soybean changed again. It is much larger and longer than before, and the transparent skin on the surface seems to be about to fall off.

Soybean stayed in the water for a day and night, and his body swelled a lot, becoming more and more like a chubby little fat man. He was so fat that he was about to break the outer layer of "clothes". Across that coat, you can vaguely see the small buds inside. Only then did I find out that the short line is where the sprouts of soybeans are.

Let the soybeans stay in the water today, and when the sprouts grow up, I will move the soybeans again.
