1. Red Ball on the Floor 地板上的红球

The ball is on the floor. It is a red ball. It is a rubber ball. The baby looks at the ball. The cat looks at the ball. The cat is black. The cat walks over to the ball. The cat hits the ball with its paw. The ball rolls on the floor. The baby smiles.

球在地板上。它是一个红色的球。它是一个橡胶球。婴儿看着球。猫看着球。猫是黑色的。猫走向球。猫用爪子击球。球在地板上滚动。婴儿笑了。
