There is a proverb that says well, "If you want to see the truth, pay attention everywhere." As long as we observe and find problems in life, new knowledge will be born. Therefore, I advise you to observe life and find problems, then your life will be more interesting.

I remember when I was six years old, I saw many small black creatures swimming freely in the water with a tiny tail behind me, so I caught a dozen of them and put them in a water bottle, ready to take them home to my mother.

I jumped up and down with a water bottle and said excitedly to my mother, "Mom, I caught an unknown black object." "What unknown objects! Isn't it just a dozen tadpoles If you want to raise it at home, raise it! " Hearing this, I danced and put the bottle in the middle of the table and watched intently.

After a few days, I found that tadpoles have two front feet under their heads, which can move forward quickly in the water. Sometimes two or three tadpoles are running in the competition! That's funny! However, a few days later, two hind legs also grew in front of the tadpole's tail. When it got up, it gave a hard push on its hind legs and a wave of its front feet, which was surprisingly fast. It jumped from here to there before it could react. After about 20 days, the tadpole's tail disappeared and its body gradually became huge. It slowly changed from black to brown, and it was still a little frog at random! As the days passed, the little frog grew bigger and bigger, and finally became a big frog. My thick thighs and agile jumping ability made me dumbfounded when I was young. ......

I found that it took me forty days to evolve from a small tadpole to a big frog. At that time, I couldn't believe it. I could find that I could evolve from tadpole to frog through my own observation!
