11、year helped whalers catch huge whales. I thought, at the time, that this was just a story but then I witnessed it with my own eyes many times. 虎鲸老汤姆1902年6月，我16岁的时候，就开始在捕鲸站工作了。在此之前我曾听说过虎鲸，它们每年帮助捕鲸人捕捉大鲸鱼。那时我以为这只是一个故事，但是后来我亲眼看见过许多次。助读讲解hear of听说(hear about)。that引导定语从句，修饰the killers，that在定语从句中作主语。On the

12、 afternoon I arrived at the station, as I was sorting out my accommodation, I heard a loud noise coming from the bay. We ran down to the shore(岸)in time to see an enormous animal opposite us throwing itself out of the water and then crashing down again. It was black and white and fishshaped. But I k

13、new it wasnt a fish.“Thats Old Tom, the killer，” one of the whalers, George, called out to me. “Hes telling us theres a whale out there for us.”Another whaler yelled(呼喊)out, “Rushoo . rushoo.” This was the call that announced there was about to be a whale hunt. 一天下午我来到捕鲸站，当我整理我的住处时，我听到从海湾方向传来了一阵巨大的喧

14、闹声。我们及时赶到岸边，看到对面有一个庞大的动物猛力跃出水面，然后又坠落到水里。它黑白相间，形状像鱼。但是我知道它并不是鱼。“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头鲸，让我们去捕猎。”另外一位捕鲸人大声喊：“快走啊走啊。”这是宣告捕鲸行动马上就要开始的呼声。助读讲解in time及时，迟早。throw oneself out of跃出。that引导定语从句，修饰the call；其中there was about to be.是announced的宾语从句。“Come on, Clancy. To the boat，” George said as he

15、ran ahead of me. I had already heard that George didnt like being kept waiting, so even though I didnt have the right clothes on, I raced after him.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 swimming

16、by the boat, showing us the way. A few minutes later, there was no Tom, so George started beating the water with his oar and there was Tom, circling back to the boat， leading us to the hunt again.“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待，所以尽管我还没穿上合适的衣服，我还是跟在他后面跑了起来。毫不迟疑地我们和其他捕鲸人都跳上船，朝海湾方向驶去。我向下朝水里望去，可以

17、看到老汤姆就在船旁边游着，为我们指路。几分钟之后，汤姆不见了，于是乔治开始用桨拍打水面，汤姆出现了，兜了个圈子转回到船边，又领着我们前往捕猎处。助读讲解head vi.朝前进。现在分词短语showing us.在句中作伴随状语。circling back.在句中作状语。Using a telescope(望远镜)we could see that something was happening. As we drew closer, I could see a whale being attacked by a pack of about six other killers.“Whatre t

18、hey doing？” I asked George.“Well, its teamwork(协作) the killers over there are throwing themselves on top of the whales blowhole to stop it breathing. And those others are stopping it diving(潜水)or fleeing out to sea，”George told me, pointing towards the hunt. And just at that moment, the most extraor

19、dinary thing happened. The killers started racing between our boat and the whale just like a pack of excited dogs.Then the harpoon(鱼叉)was ready and the man in the bow of the boat aimed it at the whale. He let it go and the harpoon hit the spot. Being badly wounded， the whale soon died. Within a mome

20、nt or two, its body was dragged swiftly by the killers down into the depths of the sea. The men started turning the boat around to go home.“Whats happened？” I asked. “Have we lost the whale？” “Oh no，” Jack replied. “Well return tomorrow to bring in the body. It wont float up to the surface for aroun

21、d 24 hours.”“In the meantime, Old Tom, and the others are having a good feed on its lips and tongue，” added Red, laughing.用望远镜我们可以看到有情况发生了。当我们行驶到更近的地方时，我能看到一只鲸受到了大约六只其他虎鲸的攻击。我问乔治：“它们在做什么？”“啊，它们在协同作战呢那些虎鲸正往鲸的出气孔上扑去，不让它呼吸。而其他那些虎鲸则阻止它潜水或逃进海里。”乔治一边指着捕猎的情景，一边告诉我。就在这时候，最惊奇的事情发生了。虎鲸们在我们的船和那只鲸之间开始追逐，就像一群兴奋的

22、狗一样。然后鱼叉准备好了，站在船头的那个人把鱼叉瞄准了那只鲸。他把叉扔了出去，恰好击中了要害。那只鲸受了重伤，没过多久就死了。过了片刻，那只鲸的尸体就被虎鲸们迅速地拖到深海中去了。捕鲸人开始调转船头回家。“怎么了？”我问道。 “我们失去了那只鲸了吗？”“噢，不。”杰克回答说。“我们明天再回来运鲸鱼的尸体。它在大约24小时以内是不会浮出水面的。”瑞德笑着补充说：“在此期间，老汤姆和其他虎鲸会饱餐一顿鲸唇和鲸舌。”助读讲解Being badly wounded在句中作原因状语。bring in带来，收获。laughing在句中作伴随状语。Although Old Tom and the other

23、 killers were fierce hunters, they never harmed or attacked people. In fact, they protected them. There was one day when we were out in the bay during a hunt and James was washed off the boat.“Man overboard! Turn the boat around！” urged George, shouting loudly.The sea was rough that day and it was d

24、ifficult to handle the boat. The waves were carrying James further and further away from us. From Jamess face, I could see he was terrified of being abandoned by us. Then suddenly I saw a shark(鲨鱼).“Look, theres a shark out there，” I screamed.“Dont worry, Old Tom wont let it near，”Red replied.It too

25、k over half an hour to get the boat back to James, and when we approached him, I saw James being firmly held up in the water by Old Tom. I couldnt believe my eyes. There were shouts of “Well done，Old Tom” and “Thank God” as we pulled James back into the boat. And then Old Tom was off and back to the

26、 hunt where the other killers were still attacking the whale.虽然老汤姆和其他虎鲸都是凶猛的捕猎者，但是它们从来不伤害人，也不袭击人。事实上，它们保护着他们。有一天，我们出海捕鲸的时候，詹姆斯从船上掉下去被水冲走了。乔治催促着并大声喊道：“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。随后我突然看到了一条鲨鱼。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。”我们花了半个多小时才把船头调向詹姆斯，当我们靠近

27、他的时候，我看到老汤姆正在水中稳稳地托着他。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”。之后老汤姆离开了，回到捕猎的地方，跟其他虎鲸一起捕鲸去了。助读讲解when引导定语从句，修饰one day。hold up举起，阻止。where引导定语从句，修饰地点the hunt(捕猎的地方)。第一步速读了解文章主题和段落大意.速读P20P21教材课文，选择最佳答案1Whats the main idea of the first story?AA hunting experience of Old Tom.BHow the killer whal
