Most cicada tunnels are as deep as 15 to 16 inches, and they are always unimpeded. The lower part is wider, but the bottom is completely closed. Where did the soil move when digging the tunnel? Why won't the wall fall down? Everyone thinks that cicadas climb up and down with their claws, but this will collapse the soil and block the house. In fact, it acts like a miner or a railway engineer. Miners support tunnels with pillars, and railway engineers reinforce tunnels with brick walls. Cicadas are as clever as they are. It covers the tunnel wall with cement. This mucus is hidden in its body and used as a plaster. Crypts are often built in the roots of plants containing juice, from which juice can be obtained. Through this story, I know the hardships of cicadas. Cicada tries to build her own house, but she thinks Cicada is a great builder. It also shows that the author compares cicada to a silently dedicated construction worker by metaphor. Therefore, we should protect these cicadas as much as we cherish the achievements of construction workers. So I call on everyone to care for animals and plants, because caring for animals and plants is like caring for yourself!
