Under the SeaUnit 3 主角是一對可愛的小丑魚(Clownfish)父子。父親瑪林(Marlin)和兒子尼莫(Nemo)一直在澳洲外海大堡礁中過著安定而幸福的平靜生活。魚爸爸瑪林一直謹小慎微，行事縮手縮腳，

2、雖然已經身為人父，卻絲毫不會影響它成為遠近聞名的膽小鬼。也正因為這一點，兒子尼莫常常與瑪林發生爭執，甚至有那么一點瞧不起自己的父親。直到有一天，一直向往到海洋中冒險的尼莫，游出了他們所居住的珊瑚礁。正當尼莫想要舒展一下小尾巴的時候，一艘漁船毫不留情地將歡天喜地的尼莫捕走，并將它輾轉賣到澳洲悉尼灣內的一家牙醫診所。在大堡礁的海底，心愛的兒子突然生死未卜的消息，對于魚爸爸瑪林來說卻無異于晴天霹靂。盡管膽小盡管怕事，現在為了救回心愛的孩子，瑪林也就只有豁出去了。它決心跟上澳洲洋流，踏上尋找自己兒子的漫漫征程。海底總動員Finding Nemo 途中瑪林與大白鯊布魯斯幾次驚險追逐,幸運的是,瑪林遇到了

7、animals that live under the sea that you and your classmates have seen in any of the ways listed above. Share what you know about these plants and animals.Whats it?whaleWhales are huge, intelligent sea mammals(哺乳動物). They breathe air through blow-holes(鯨頭頂的呼吸孔) into lungs (unlike fish who breathe us

8、ing gills鰓). Whales have smooth, shiny, streamlined(流線型)bodies that move easily through the water. What is a whale? There are two types of whales alive today:toothed whales (齒鯨類) and baleen whales (須鯨類). Toothed whales have teeth and a single blowhole. They feed on eating fish and other sea mammals.

9、 Baleen whales are larger than toothed whales. They are filter feeders (濾食者) that use baleen to sieve (過濾) food, and have two blowholes. Classification of whales Baleen whalesThis group includes the largest known animal species, the Blue Whale. Killer whales (虎鯨) belong to toothed whales, who are th

10、e biggest carnivore(食肉動物) of the sea, killing all kinds of animals, even the huge blue whale.They usually work in a team.Killer whales虎鯨也屬于齒鯨類。它體長近10米，重7噸8噸，雌的略小一些，也有6米8米。虎鯨膽大而狡猾，且殘暴貪食，是遼闊海洋里“橫行不法的暴徒”。虎鯨的英文名稱有殺鯨兇手之意。不少人在海上屢屢目睹虎鯨襲擊海豚、海獅以及大型鯨類的驚心動魄的情景。虎鯨的口很大，上、下頜各有二十幾枚10厘米13厘米長的銳利牙齒，牙齒朝內后方彎曲，上下頜齒互相交錯搭

11、配，與人的兩手手指交叉搭在一起的形式相似。這不僅使被擒之物難逃虎口，而且還會撕裂、切割獵物。虎鯨很好辨認:在它的眼后方有兩個卵形的大白斑，遠遠看去，宛如兩只大眼睛；其體側還有一塊向背后方向突出的白色區域，使它獨具一格。 虎鯨身體強壯，行動敏捷，游泳迅速，每小時可達30海里。游泳時，雄鯨高達1.8米的背鰭突出于水面上。虎鯨是名符其實的海中猛虎。 有人在一頭虎鯨的胃里發現十幾頭海豚和同樣數量的海豹。其實即便是動物之王的藍鯨若遇到一群虎鯨圍獵，它也難逃被獵殺的厄運。圍攻藍鯨時，虎鯨分工十分精密：一些虎鯨在它的兩側，兩頭虎鯨在它的前面，另外兩頭在它的后面，阻擋藍鯨逃跑；另一些虎鯨則迫使藍鯨沉在水下，不

12、讓它突出水面呼吸；還有一些虎鯨在它的腹部底下監視，防止它潛水溜掉。藍鯨先被咬去背鰭，尾葉又被撕碎，使它無法游動。這時虎鯨們一哄而上，大塊大塊地撕咬藍鯨的肉，共享美餐。此外,虎鯨還有一種奇特的嗜好，即最喜歡吃鯨的唇和舌。一頭巨鯨被捕鯨炮擊斃，在海面漂浮或被船拖行時，虎鯨會趁火打劫，鉆到死鯨口中，將巨鯨的唇、舌掠食一空。值得一提的是,虎鯨雖然兇殘異常，但從未目擊或聽到虎鯨傷害人類的事例，而且經過馴養的虎鯨，性情溫順，甚至會表演許多精彩節目。 Killer whalesWhat do you think is happening in the picture?Read the introductio
