There were two cows chatting over the fence between their fields。
The first cow said，“I tell you，this mad-cow-disease is really pretty scary。They say it is spreading fast；I hear it have hit some cows down on the Johnson Farm。”
The other cow replied，“I ain't worried，it don't affect us ducks。”
两只牛隔着篱笆聊天。
