Curious argumentative essay 600 words
Everyone comes to this colorful world from crying. Childhood is like a history book, recording everything about me.

Naive romance also aroused my curiosity.

I remember last summer, I saw several ladybugs in the flowers in front of my house. Seeing these ladybugs, I had some ideas.

I caught some ladybugs home, put them in a transparent bottle and began to observe. Find out where its eyes are first. First of all, I'm sure ladybugs have eyes. Otherwise, how can it see? But I can't find it anywhere. Maybe its eyes are too small. So I invited a magnifying glass to help. Looking under the magnifying glass, I found the answer: in front of the ladybug's round body, there is a round little thing, maybe this is its head; There is a small black spot at each end of its head. It must be the eyes of a ladybug.

How many feet does a ladybug have? I took out a caught ladybug and tried to turn its body upside down to see how many feet it had, but it was running around on the table and I couldn't catch it. Finally, I caught it, but somehow, this ladybug only has five feet. So I took out another one to make sure that all ladybugs have only five feet, so they can fly accidentally. I have no choice. I took out another one and it flew away. I kind of want to give up. But when I thought about it, how could I give up so easily? So I found my confidence again. Carefully took out a ladybug and found it successfully: it turns out that the ladybug has six feet. There is one last question: Are ladybugs pests or beneficial insects? I put ladybugs in the yard, and through observation, I found that only one of them is beneficial, that is, ladybugs. Looking up the information from the book, I also know that the ladybug is orange with seven black spots on its back, also called Sister Hua. Ladybugs eat a pest called aphids, also called moths. They put their mouths into the juice of the plant epidermis, making the plant turn yellow and die. Ladybugs can eat more than 100 aphids a day, so only ladybugs are beneficial and others are pests.

I let out a cry of excitement, because I finally discovered the secret of the ladybug: the ladybug's eyes are at both ends of its small head; Ladybugs have six feet; Among ladybugs, only ladybugs are beneficial insects.

Ah, I'm proud of my discovery! I have a curious heart. I am curious about everything in the world and will ask a series of strange questions. I know that only by consolidating the knowledge in books and reading more extracurricular books can we solve these problems.
