2. How did Old Tom help James? Old Tom kept the shark away and then held firmly James up in the water.
James was washed off the boat and was carried further and further. And there was a shark near by. 3. Why he did this?
Because old Tom wanted to help his human friends传统捕鲸(whale hunting)方法:6名捕鲸者离开大船，乘小艇追逐鲸鱼，小艇通常长8.5公尺，装备有具倒钩的捕鲸铦和长索。鲸一旦被铦刺中，便带着绳索逃遁，直到筋疲力尽浮出水面，人们在那儿用捕鲸枪(一种更长的捕鲸铦)将它杀死，用绳索拖到大船边，用有刃的长枪割取油脂，并把尸体抛弃。由于鲸油是贵重的工业原料，历史上欧洲和美洲一些国家的捕鲸活动长盛不衰。自20世纪中叶起，由于过度猎捕导致资源衰退以及国际上对捕鲸的限制，捕鲸业已趋衰落。 现代捕鲸业: 挪威人福伊恩发明了一种捕鲸炮，用来发射内充炸药的标枪。后来又使用了动力船，与捕鲸炮相得益彰，这些方法使用至今几乎没有什么变化。 人类和虎鲸联合来猎杀我，真是太残酷了！
