英文小作文：

My Heart Is Across My Chest

My chest is a map of my heart, beating and thumping with every beat. I can feel its rhythm, its warmth, and its power. It is my lifeline, my source of strength, and my constant companion. When I am sad, it comforts me; when I am happy, it celebrates with me; and when I am scared, it provides me with courage and assurance. My heart is always with me, across my chest, and it never leaves me alone. It is my constant reminder of who I am and what I am capable of. It is my guiding light in this world, and I am grateful for it every day.
