17、大的动物猛力跃出海面，然后又坠落到水里。它黑白相间，样子像鱼，但我知道它并不是鱼。“那是老汤姆，是虎鲸。”一位叫乔治的捕鲸人高声对我说，“它是在告诉我们那边有一头鲸，叫我们去捕猎。”另外一位捕鲸人大声喊叫：“快走啊走啊。”这是宣告猎鲸行动马上就要开始的呼声。“克兰西，快来，上船去。”乔治在我前面边跑边说。我以前就听说过，乔治不喜欢等人，所以尽管我还没有穿上合适的衣服，就跟在他后面跑起来。一刻不停地，我们和其他捕鲸人都跳上渔船，朝海湾方向驶去。我朝水里望去，可以看到老汤姆就在渔船旁边游着，为我们指路。几分钟之后，汤姆不见了，于是乔治开始用浆拍打水面。汤姆出现了，转回到船边，又领着我们前往捕猎处。

18、通过望远镜，我们可以看到远处有情况发生了。走近一看，原来是一头大鲸受到约六七条虎鲸的攻击。我问乔治：“它们在干什么呢？”“啊，它们在协同作战呢那些虎鲸正在往那头鲸的出气孔上扑去，不让它呼吸，而其他那些虎鲸则阻止它潜水或逃跑。”乔治一边指着捕猎的情景，一边告诉我。就在这时候，最精彩的场面出现了。虎鲸们在我们的渔船和那头鲸之间追逐，就像一群兴奋的猎狗一样。于是，猎鲸叉准备好了。站在船头的那个人把叉瞄准了那头鲸，扔了出去，恰好击中了要害，鲸受了重伤，没过多久就死了。过了片刻，鲸的尸体就被虎鲸们迅速拖向深海中去了。捕鲸人于是调转船头往回走。“怎么啦？”我问道，“我们失去鲸了吗？”杰克回答说：“不，我们

19、明天再回来运鲸鱼的尸体。它在24小时以内是不会浮出水面的。”雷德笑着补充说：“在这段时间里，老汤姆和其他虎鲸会饱餐一顿的，鲸唇和鲸舌就是它们的美食。”虽然老汤姆和其他虎鲸都很凶恶，但是它们从来不伤害人，也不袭击人。事实上，它们还保护人。有一天，我们出海捕鲸的时候，詹姆斯被冲下水去了。乔治大声喊道：“有人落水了！把船头调回去！”那天海上波涛汹涌，很难调转船头。海浪把詹姆斯冲得离我们越来越远。从詹姆斯的脸上我能看出他非常恐慌，生怕被我们遗弃。随后我们看到一条鲨鱼。我尖叫起来：“瞧，那边有一条鲨鱼。”雷德回答说：“别着急，老汤姆不会让它靠近的。”我们花了半个小时才把船头调转过来，回到詹姆斯落水的地方

20、。当我们靠近他的时候，我看到老汤姆正在水中稳稳托着詹姆斯。我几乎不相信自己的眼睛。当我们把詹姆斯拉上渔船的时候，大家都欢呼着“老汤姆，好样的”“感谢上帝”。后来，老汤姆离开了，回到捕猎的地方，跟其他虎鲸一起捕鲸去了。,二、课文精选段落背诵，请注意文段中ving的用法Old Tom the Killer Whale Without pausing we jumped into the boat with the other whalers and headed out into the bay.I looked down into the water and could see Old Tom
