IV. 书面表达（参考范文）
Last night, I dreamt that one Sunday morning, my classmates and I went to play in a park. Suddenly, we saw a bright light behind some trees. We walked closer and found three aliens! They had big green eyes, small mouths, and blue skin. Their arms were very long and thin.
We were frightened at first, but then one alien smiled. They seemed friendly and curious about us. One alien pointed at my watch and made a soft sound. We tried to talk with them using gestures. They showed us a small glowing stone from their planet. It was amazing!
We spent an hour together, drawing pictures on the ground to communicate. When they left in their spaceship, we waved goodbye. It was an unforgettable dream.
