课文注释 Unit 3 Under the Sea
Unit 3 Under the sea课文注释①It was a time when the killer whales, or “killers” as they were then called, helpedthe whalers catch the baleen whales that were on their annual migration. 那个时期, 虎鲸(当时被称为“杀手”) 帮助捕鲸人在每年须鲸迁徙时捕捉须鲸。
killer whales虎鲸, 又叫逆戟鲸, 以鱼, 海鸟, 海龟和哺乳动物为食。
虎鲸以体魄健壮、性情凶狠而闻名于世, 但在人工饲养环境中经调教、训练之后, 可变得十分驯服。
baleen whales须鲸类。
以进食方式的不同, 鲸分为须鲸和齿鲸两类。
须鲸类中常见的是蓝鲸。
②We ran down to the shore in time to see an enormous animal throwing itself outof the water and then crashing down again. 我们及时赶到岸边, 看到一个庞大的动物猛力跃出水面, 然后又坠落到水里。
throw itself out of the water形象地表现了鲸跃出水面的动作。
throw的用法比较灵活, 能表达出丰富的含义。
如：He throws his weight about. 他乱用权利。
I felt discouraged when he threw cold water on my idea. 他向我的想法泼冷水时, 我感到很沮丧。
She threw herself into a chair and began to cry. 她倒在椅子上, 开始哭泣起来。
He has thrown himself into gardening. 他全身心地投入园艺事业。
The fire threw hundreds of workers out of work. 大火使几百工人失业。
③This was the call that announced there was about to be a whale hunt. 这是宣告捕鲸行动马上就要开始的声音。
be about to do即将；将要。
如：When we were about to close down the business, the bank came to our rescue. 我们几乎要停业时, 银行(借贷)为我们救了急。
As I am about to start on a journey, l shall not be able to begin the work before I return.我要出发去旅行了, 所以在我回来之前我无法开始这项工作。
Another journey of challenge and danger was about to begin. 又一段充满危险和挑战的旅程就要开始了。
④ Well, they’re working as a team— the killers over there are throwing themselveson top of the whale’s blow-hole to stop it breathing.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。
to stop it breathing是动词不定式短语做目的状语。
如：They went there to help get in the autumn crops. 他们去那里是为了帮助秋收。
Let's do some exercise to warm up a bit. 咱们做些锻炼热热身。
They formed a special group to look into the matter. 他们成立了一个特别小组来调查此事。
stop … (from) doing句型的意思是防止(制止)某人做某事。
如：I am leaving, so don't try to stop me from going. 我要走了, 别想阻拦我。
We must stop her telling others about it. 我们要制止她把此事告诉别人。
问题：你知道stop doing和stop… (from) doing 两个句型有何区别?试以例句说明两者的区别。
⑤The first thing I became aware of was all the vivid colours surrounding me —purples, reds, oranges, yellows, blues and greens.我首先注意到的是我周围那些鲜艳的色彩——紫色、红色、橘黄、明黄、蓝色、绿色等。
aware of 意识到；知道；明白；觉察到。
如：Nerves send messages to the brain. They make people aware of what their bodies are feeling. 神经把信息传送到大脑, 让人觉察到自己身体的感觉。
还有一个常见的句型是be aware that。
例如：Everyone was aware that they didn’t get along well with each other. 大家都知道他们相处不和睦。
Are you aware that it is getting windy outside? 你注意到外面起风了吗?⑥I especially loved the little orange and white anemone fish that hid in thepoisonous tentacles of the sea anemones. 我特别喜欢那些橙白相间的小海葵鱼, 它们藏在海葵有毒的触须里。
sea anemone海葵, 一种海生腔肠动物。
它体表坚韧, 身体的主干是一个能够伸缩的圆筒, 其一端固定在岩石上, 另一端是围绕着触须的嘴。
海葵在水中不受惊扰时, 触手伸张得像葵花, 所以叫做海葵。
海葵的食性很杂, 食物包括软体动物、甲壳类和其他无脊椎动物甚至鱼类等。
anemone fish海葵鱼, 俗称小丑鱼, 一种海洋鱼类, 可长至十厘米。
海葵鱼最大的特点是寄生于剧毒的海葵中, 海葵鱼对海葵的毒汁具有先天的免疫功能, 因此他们有着相互依赖的共生关系。
⑦It seemed there was a surprise waiting for me around every corner as I exploredsmall caves, shelves and narrow passages — the yellow and green parrotfish hanging upside down, gathering tiny plants off the coral with its hard bird-like mouth；a yellow-spotted red sea-slug sliding by a blue sea-star；an orange and blue-striped angelfish looking straight at me；a large wise-looking turtle passing so close to me that I could have touched it. 当我在小石洞、岩石和窄通道之间探索时, 似乎每个角落都有令我惊奇的东西等待着我——黄绿相间的鹦嘴鱼倒挂着, 用鸟儿一样的硬嘴去收集珊瑚上的植物；一条带着黄斑点的红色海蛞蝓从一个蓝色的海星旁边滑落下去；一条身着橘黄色蓝条纹的天使鱼直盯着我；一只长相聪慧的大海龟紧贴着我的身旁而过, 几乎伸手便可触及。
parrotfish鹦嘴鱼, 拥有蓝、绿、红及黑的颜色。
鹦嘴鱼有很多小牙齿, 这些牙齿甚似鹦鹉的嘴, 故叫做鹦嘴鱼。
鹦嘴鱼主要以珊瑚为食, 并会将无法消化的珊瑚或岩石排泄出来而形成沙, 所以鹦嘴鱼在珊瑚礁生态系统中, 扮演了相当重要的“珊瑚转换成沙”的角色。
短语upside down简单而形象地表达了“倒悬”这个意思, 另有短语inside out也有同样的效果。
如：You’d better turn the bottle upside down to empty out the oil. 你最好把瓶子倒过来, 把瓶里的油控干净。
Why? Look at Jim. His jacket is inside out. 怎么了? 看看吉姆, 他的衣服穿反了。
⑧ The re were other creatures that I didn’t want to get too close to— an eel with itsstrong sharp teeth, with only its head showing from a hole, watching for a tasty fish (or my tasty toe!)；and the giant clam half buried in some coral waiting for something to swim in between its thick green lips. 还有一些其他的动物, 我不想太靠近它们——一条带有利齿的海鳗, 从洞穴里探出头来, 望着可供美餐的鱼过来(或者在等着我的美味脚趾伸过去!)；一个巨大的蛤蜊半掩在珊瑚礁中, 等待着有什么东西游过来, 游到它宽厚的绿嘴唇中去。
eel鳗鱼, 一种长的蛇形的无鳞海洋或淡水鱼, 产于世界各地, 体长一般不超过l米。
海鳗具有锐利的牙齿、强而有力的颚及敏捷的反射动作, 经常徘徊、躲藏在珊瑚区, 并以此为家。
clam蛤；蚌；蚶。
一类具有一对硬壳的软体动物, 通常栖居在水底的泥土中, 种类很多.分布很广。
⑨ The water was quite shallow but where the reef ended, there was a sharp drop tothe sandy ocean floor. 水很浅, 但到了珊瑚礁的尽头, 就有一个陡坡, 一直降到满是沙子的海底。
a sharp drop陡直向下的坡。
sharp一词含义丰富, 包括“锐利的；锋利的；明显的；强烈的；刺耳的；急剧的, 精明的；敏捷的”等。

绿海龟是世界上最大的硬壳海龟，体重最重可达204公斤。
目前全世界80多个国家的海岸线上都有它们的踪迹。
现在就让我们一起去探知绿海龟的生活习性吧！Green Sea TurtlesGreen sea turtles are the world’s largest species of hardshelled seaturtle. While most of them weigh about 136 to 181 kilograms, some canbe as heavy as 204 kilograms.These turtles are found nesting along the coastline of more than 80countries, with the largest nesting populations found in Costa Rica and Australia.Green sea turtles spend most of their lives underwater, where they can rest for up to five hours at a time before coming up for air. Green sea turtles are also known to sunbathe(晒日光浴) on land.Unlike most other sea turtles, adult green sea turtles eat a primarily plantbased diet consisting of seaweed and sea grass. Scientists believe these green foods give the sea turtle’s fat its green color. The shell of the green sea turtle is usually a shade of brown or olive.Similar to other sea turtles, green sea turtles migrate long distances between their feeding grounds and their nesting sites, with recorded distances of longer than 2，600 kilometers.Female green sea turtles leave the water in order to lay eggs on the beach and will choose thesame nesting spot as where they were born. A female will dig out a nest and lay about 115 eggs. Then she’ll cove r the eggs with sand and return to the sea. After about two months, the babies will hatch(孵化) from their eggs.The first few years of a green sea turtle’s life are spent floating at sea, where they feed on plankton(浮游生物). As they grow older, the turtles move to waters along the coast where they find sea grass to eat.Adult green sea turtles face many threats, primarily from humans, including injuries from boats, being caught in fishing nets and pollution. Newly hatched sea turtles are also at risk of being hunted by animals such as birds, crabs, and raccoons as they move from their nests out to the sea.Section ⅠWarming Up & Reading—Comprehending重点单词写作词汇1.witness v t.当场见到；目击n. 目击者；证人；证据2.opposite prep. 在……对面adj. 相对的；相反的3.pause v i.& n. 暂停；中止4.teamwork n．协作；配合5.relationship n．关系；血缘关系；交往6.urge v t. 催促；极力主张；驱策7.meantime ad v. 其间；同时拓展词汇8.annual adj.每年的；按年度计算的n．年刊；年鉴→annually ad v.每年；一年一度地9.accommodation n．住所；住宿→accommodate v t.提供住宿10.flee v i.逃避；逃跑v t.逃离→fled(过去式)→fled(过去分词)11.drag v t.拖；拉；扯→dragged(过去分词)→dragging(现在分词)12.depth n．深(度)；深处→deep adj.深的→deepen v．加深13.abandon v t.放弃；遗弃；抛弃→abandoned adj.被遗弃的；放纵的14.conservation n．保存；保护→conserve v．保存阅读词汇15.anecdote n．轶事；奇闻16.shore n. 岸；海滨17.yell v i. 大叫；呼喊n. 叫声；喊声18.dive v i.& n．跳水(的动作)；潜水(的动作)；俯冲19.harpoon n.

Unit 3 Under the sea
Unit 3 Under the sea当我们提及“Under the sea”，一幅神秘而迷人的画卷便在脑海中徐徐展开。
那是一个充满未知和奇迹的世界，一个与我们陆地生活截然不同的领域。
在海洋的深处，光线逐渐变得微弱，直至完全消失。
然而，生命的迹象并未因此而绝迹。
在这片黑暗中，有着独特的生物适应着极端的环境。
那些会发光的深海鱼类，它们身上的光芒如同夜空中闪烁的星星，为这片黑暗带来了一丝神秘的色彩。
各种奇异的生物形态令人惊叹。
有着柔软身躯的章鱼，能够随心所欲地改变自身的颜色和形状，仿佛是海洋中的魔术师。
还有那巨大而古老的鲸鱼，它们在海洋中优雅地游动，每一次呼吸都像是对海洋的深情问候。
海洋中的植物也有着自己独特的生存方式。
海草在水流中轻轻摇曳，为众多的小鱼小虾提供了栖息和庇护之所。
珊瑚礁则像是海洋中的城堡，五彩斑斓，成为无数海洋生物的家园。
海洋不仅是生物的乐园，也是地球上气候调节的重要因素。
它吸收着大量的热量，调节着全球的气温。
同时，海洋的洋流就像是巨大的传送带，将温暖和寒冷的海水进行交换，影响着世界各地的气候。
然而，人类活动却给这片神奇的海洋世界带来了巨大的威胁。
过度捕捞使得许多鱼类种群数量急剧减少，一些物种甚至濒临灭绝。
塑料垃圾在海洋中四处漂浮，被海洋生物误食，严重影响了它们的生存。
石油泄漏等事故更是给海洋生态带来了灾难性的打击。
为了保护海洋，我们每个人都应当行动起来。
减少使用一次性塑料制品，支持可持续的渔业捕捞方式，参与海洋保护的志愿活动等等。
海洋，这个充满魅力和奥秘的世界，等待着我们去探索、去保护。
让我们共同努力，让“Under the sea”的世界永远保持着它的神奇与美丽。
我们还应该加强对海洋的科学研究。
通过先进的技术手段，深入了解海洋生物的生态习性、繁殖规律以及它们与海洋环境的相互关系。
这不仅有助于我们更好地保护海洋生物，还能为开发利用海洋资源提供科学依据。
同时，建立更多的海洋保护区也是至关重要的。
