We start to grow from the moment we were born. We keep growing and growing until we become adults. We become bigger, taller and heavier.

As we grow, important parts of our bodies change. Our bones (骨头) grow bigger and longer to make us taller and stronger. Our muscles (肌肉) are bigger in order to support our bigger bodies. Our skin (皮肤) also grows as our bodies get bigger.

While the parts of our bodies grow, they do it at different speed. For example, one’s nose might have finished growing, but the other parts of the face are still changing.

Similarly, each child grows at his or her own speed, so we see children in all kinds of shapes and sizes. Not one of them is the same as another except for some twins. Some grow faster than others, so they look bigger and taller. Some grow at a slower speed, and may be smaller and shorter.

Our genes also determine how much we grow. It is unlikely (不太可能的) to have short parents for tall children. Parents who are tall are just unlikely to have very short children.

No matter how quickly and how much we grow, each person is different. That is the beauty of human growth.
