Recently, many people in our class are raising silkworms. Why? It turns out that we have learned the text "silkworm girl", so there are more and more silkworm breeders in our class. Even I want to raise silkworms. I want to see what the silkworms look like when they change color, how small their eyes are, and so on. Coincidentally, there is a mulberry tree behind my house. I also decided to raise silkworms.
