Grasshopper Bet

Children, if you have heard the story "The Bad Grasshopper", you will know that grasshoppers are pests that harm crops. Now, let me tell you another story about the "grasshopper bet".

The heavy rain fell for a long time. After the heavy rain, the ridges were filled with rainwater. The grasshopper had just finished stealing the crops and had nothing to do. He shouted around: "Hey, who can beat me! Who dares to stick his head into the puddle!"

Several ants crawled over, Asked: "Are you talking about piercing Mengzi?"

The grasshopper flicked his hind legs and said: "It's nothing to pierce Mengzi! My head is plunged into the water, and it doesn't matter if I stay there for a few hours. Believe it or not. ?"

The ants laughed and shouted: "Don't believe it, don't believe it!"

"If I can't drown, I will kick each of you twice - as hard as you want. Just try as hard as you can; if I can't stay for a few hours, you can bite me twice each, and you can bite me as much as you like, how about this?" The grasshopper made a bet.

After discussion, the ants agreed, so the grasshopper put his head into the water.

10 seconds, 20 seconds passed, the grasshopper remained motionless, and the ants cheered: "It worked, it worked!"

1 minute, 2 minutes passed, The ants admired the grasshopper even more: "It's amazing! It's amazing!"

Ten minutes and 20 minutes passed, and the grasshopper still immersed his head in the water without moving. The ants looked at me and I looked at you, and they all said: "No, no, this grasshopper has probably drowned. Let's leave quickly!"

The ants found a lot of food. , and sent them back to the hole... A few hours later, they thought of the grasshopper and ran to the ditch to look, only to see that the grasshopper was still stuck in the water motionless.

At this time, two praying mantises flew over and said, "Hey, what is that grasshopper doing with its butt sticking out?" After saying that, it landed.

An ant said: "He drowned!"

Suddenly, the grasshopper moved. He actually raised his head from the water and said: "Drown? What a joke. ! I can stay in the water like a fish! Little ant, come here and give me a kick!"

The ants were shocked: Why, the grasshopper didn't drown? He kept his head in the water for so long, why couldn't he drown?

Just as the grasshopper retracted his legs to kick the ants, he suddenly saw two praying mantises staring at him. He was frightened! Just as he was about to fly, he was held down by the mantis.

The mantis said: "You big pest, what tricks are you doing! Now, I want to see if I can drown you!" As he said, he pushed the grasshopper into the water—— This time, his head was above the water, but his belly was submerged.

The grasshopper shouted: "Let me go, I'm going to drown!"

The ants were all dumbfounded: Why, my head can't be drowned in the water? , the belly is in the water but it is drowning!

After a while, the mantis pulled the grasshopper up. When he saw it, he was already motionless. This time, he really drowned.

After working for a long time, the ants finally understood: It turns out that grasshoppers do not breathe through their mouths. There is a trachea on each side of his belly, which communicates with the outside of the body through the valve - grasshoppers breathe through the valve on the stomach. Therefore, a grasshopper will not die if its head is immersed in water, but it will not survive if its belly is immersed in water!
