今天老师布置了一项特别的作业,就是叫我们回家仔细观察鸡蛋的结构,并把蛋黄和蛋白分开,看看里面有什么秘密。回到家里,我迫不及待地从冰箱里随意地拿出一枚鸡蛋,在我仔细地观察下,看到鸡蛋的一头是尖尖的,另一头是圆圆的。我拿起放大镜,看到鸡蛋的蛋壳很薄,表面上凹凸不平,还有许多小孔,就像月球的表面,有趣极了! Today, the teacher arranged a special assignment, that is, let us go home and carefully observe the structure of the egg and separate the egg yolk from the protein to see if there is any secret inside. Back home, I could not wait to come up with an egg from the freezer. As I watched closely, I saw that one end of the egg was pointed and the other end was round. I picked up the magnifying glass and saw the shell of the egg was very thin, uneven on the surface, and many small holes, like the surface of the moon, very interesting!
