四、阅读理解。
Day and night are caused by the rotation of the Earth. When one side of the Earth faces the Sun, it experiences daylight, while the other side faces away from the Sun and experiences darkness. This cycle repeats as the Earth rotates on its axis. During the day, the Sun provides light and warmth, making it possible for plants to grow and for animals to be active. At night, the Moon and stars become visible in the sky. Day and night play a significant role in the Earth's ecosystem and the lives of living organisms.

作文题答案
During the day, the Earth rotates, and the side facing the Sun experiences daylight, providing warmth and light. This is called daytime. I enjoy playing outside, reading books, and having picnics with my family during the day. At night, the other side faces away from the Sun, and it becomes dark. This is called nighttime. I like stargazing, telling stories, and watching the moon during the night. Day and night are fascinating because they show us the beauty of nature's cycle.
