传统捕鲸方法: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。
现代捕鲸业肇: 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。

Then, you will assign different oceanographers to different projects and explain to them how best to work together.Family-x fileYounger Xpeditioners:Pick one project,and learn more about it through its photo gallery. Then, create a poster based on the animals and terrain(地形). Make sure to label each animal that you draw. Show your poster to your family and describe to them what you have drawn.Older Xpeditioners:Learn more about each of the projects:Where (in the ocean) would oceanographers go to study them? What animals might oceanographers study in the project? Which types of oceanographers would you assign for each project and how would they work together?Finally,think about the ways in which the different general kinds of oceanography might relate. Why is it important to look at the ocean as an entire system, rather than as distinct parts? How might looking at each separate part and the ocean as a whole impact conservation efforts? Practise your speech for the conference in front of your family.1.

选修7 Unit 3 Under the sea Reading(附译文)

选修7 Unit 3 Under the sea - ReadingOLD TOM THE KILLER WHALE虎鲸老汤姆I was 16 when I began work in June 1902 at the whaling station. I had heard of the killers that every 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.On the afternoon I arrived at the station, as I was I sorting out my' accommodation, I heard a loud noise coming from the bay. We ran down to the shore 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 fish-shaped. But I knew it wasn't a fish."That's Old Tom, the killer," one of the whalers, George, called out to me. "He's telling us there's a whale out there for us."Another whaler yelled out, "Rush-oo ...rush-oo." This was the call that announced there was about to be a whale hunt."Come on, Clancy. To the boat," George said as he ran ahead of me. I had already heard that George didn't like being kept waiting, so even though I didn't 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 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.Using a telescope 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."What're they doing?" I asked George."Well, it's teamwork - the killers over there are throwing themselves on top of the whale's blow-hole to stop it breathing. And those others are stopping it diving or fleeing out to sea," George told me, pointing towards the hunt. And just at that moment, the most extraordinary thing happened. The killers started racing between our boat and the whale just like a pack of excited dogs.Then the harpoon 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 moment 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."What's happened?" I asked. "Have we lost the whale?""Oh no," Jack replied. "We'll return tomorrow to bring in the body. It won't float up to the surface for around 24 hours." "In the meantime, Old Tom, and the others are having a good feed on its lips and tongue," added Red, laughing.Although Old Tom and the other 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 difficult to handle the boat. The waves were carrying James further and further away from us. From James's face, I could see he was terrified of being abandoned by us. Then suddenly I saw a shark."Look, there's a shark out there," I screamed."Don't worry, Old Tom won't let it near," Red replied.It took 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 couldn't 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 hunt where the other killers were still attacking the whale.1902年6月，我开始在捕鲸站里工作，那时我才16岁。
