The first stanza of Shadow is a declarative sentence. "Shadow" is a children's song based on life phenomena. It uses personification and metaphor techniques and is full of childlike innocence. It describes the characteristics of shadows and people being inseparable, and expresses the author's love for shadows. The children's song has two sections, concise language, neat sentence structure, and even-numbered sentences that rhyme, making it catchy to read. The text is accompanied by two illustrations. The first one is of children playing hopscotch, with the shadow in front and the shadow behind in the first section. The second one is of a situation of roller skating, with the shadow on the left and the shadow in the right section of the second section. Shadows appear in both pictures, aiming to help students understand the meaning of children's songs based on their life experiences.
