微笑的老師在生物課開始時向學生問好

Teacher enters the class with a smile. “Good morning, students! Today, we are not just studying Biology… we are going on a journey into the world of life!” Students look excited. One student asks, “Sir, what do you mean by world of life?” Teacher replies, “Biology is the study of living things, and it has many branches—each one like a different path in a big forest.”
