Once Sima Guang and his friends played in the yard(庭院). There was a big water vat(水缸)in the yard. A boy climbed(爬)up to the vat to play, and fell into the vat. The vat was tall and big with so much water in it. The other children cried out and ran away. But Sima Guang picked up a stone and broke the vat. Then the water in the vat came out. The boy was saved(得救)。
