7 . In 1928 some porpoises were photographer working like beavers to push ashore a waterlogged mattress.1928年，有人拍攝到了海豚像海狸一樣把浸透水的床墊推上岸的情景。
8 . On the occasions when they have pushed to shore an unconscious human being they have much more likely done it out of curiosity or for sport, as in riding the bow waves of a ship.當它們偶爾把一個失去知覺的人推到岸邊時，更大的可能是出於好奇或遊戲，就像它們追逐被船首犁開的浪花一樣。
9 . Almost any day a young porpoise may be seen trying to turn a 300-pound sea turtle over by sticking his snout under the edge of his shell and pushing up for dear life.幾乎每天都可以看到一隻小海豚把鼻子頂入一隻300磅重的海龜的硬殼下面，拚命地把它翻過來。
