I finally know why dragonflies drink 400 words of water.

One day, I was playing by the river, and suddenly I saw a dragonfly gently beside the river and flew away. I feel very curious. "Dragonfly has some water" is an idiom. Everyone understands its meaning, but why does dragonfly want some water? I couldn't help wondering, so I hurried home and asked my mother. Mom doesn't know either. She encouraged me to find the answer by myself.

Despite the scorching sun, I arrived at Xinhua Bookstore. When I got there, I never expected to rummage through the whole set of "100,000 Why" and found no reason not to touch the water. I was about to leave the bookstore in frustration when I suddenly saw a big slogan on the wall "Don't let go of any questions". Suddenly, my face was burning, and I quickly turned to the book to find the answer, but I still found nothing.

In the days to come, I looked at every book around me all the time, trying to find the reason for "skimming".

One morning, I was looking through the desk calendar on my father's desk, and I accidentally saw a short article "Why do dragonflies want water?" I shouted happily, "Mom, come and see it! I found the answer! " The mother who was washing her face rushed over. We read the passage together before we suddenly realized. It turns out that "dragonfly water" means dragonflies are laying eggs!
