Protecting Dragonflies One morning in summer, after the rain, I went out to play with my neighbor's little brother.

When we came to the small garden, we saw that the willow branches were blown by the wind like fairy's hair, which was very beautiful. Many dragonflies among the flowers are busy catching mosquitoes.

Some fly high into the air, and some land on flowers and plants. At this time, a big dragonfly landed on the flowers and plants beside my little brother.

My little brother stared at the big dragonfly and thought, What a big dragonfly! If only I could catch it and make a specimen! He crept up to the dragonfly. He reached out his little hand to catch the dragonfly, which flew away.

The little brother shouted, "Sister, come quickly. Look at this dragonfly! Come and help me catch it and go home to make a beautiful specimen. " He shouted and ran after the dragonfly.

I quickly stopped him and said, "Little brother, dragonflies are beneficial insects. It can eat many mosquitoes every day. You must catch it and make a specimen. Can it still catch mosquitoes? " If all children do as you do, it will naturally become a mosquito world. How terrible. "The more he listened, the more afraid he became. He never caught a dragonfly again.

At noon, I happily led my little brother home.
