We see a woman swimming[1] at night in a dark sea．Suddenly，she is pulled underwater．She surfaces②，cries in fear③，then disappears forever．This is the opening scene from the 1975 film Jaws，showing a shark attack[2]．It tells the story of a great white shark that attacks and kills swimmers[3]．Jaws was a great success④，attracting huge audiences and winning many awards[4]．It strengthened people's long-held⑤ idea of the great white shark as a dangerous animal． [1]see a woman swimming为“see＋宾语＋宾语补足语”结构，意为“看到某人正在做某事”。 [2]showing a shark attack为动词-ing形式作后置定语，修饰the opening scene。 [3]that attacks and kills swimmers为that引导的定语从句，修饰先行词a great white shark。 [4]attracting huge audiences and winning many awards为两个并列的动词-ing形式短语作定语，修饰a great success。 People have always been scared⑥ of sharks，but Jaws made things worse．It made people frightened of⑦ sharks，especially of the great white shark．Many people who saw the film[5] started to believe that sharks were bad animals that ate humans[6]．Some people stopped swimming⑧ in the sea，afraid of⑨ the horrible creature from the film[7]．Other people started fishing for sharks，killing as many as they could[8]．At that time，nobody cared if sharks were killed，or how many were killed．People just wanted them killed[9]． [5]who saw the film为定语从句，修饰先行词many people。 [6]that ate humans为定语从句，修饰先行词animals。 [7]afraid of...为形容词短语作状语。 [8]killing as many as they could为动词-ing形式短语作结果状语。 [9]wanted them killed为动词后加复合宾语，过去分词killed作宾语补足语。 After 1975，the number of⑩ large sharks around America fell quickly，and soon fell around the world．This was not only due to⑪ fear of sharks，but also finning⑫．[10]Finning is a type of fishing where sharks are caught and their fins cut off⑬．[11] The sharks are thrown back into the sea where they die slowly and painfully[12]．The fins are used in shark fin soup．Finning kills millions of⑭ sharks a year． [10]本句中not only...but also...意为“不仅……而且……”，连接两个并列成分。 [11]本句中动词-ing形式作主语，谓语动词用单数形式；where sharks are caught...为定语从句，修饰a type of fishing。 [12]此处where引导定语从句，修饰先行词the sea。　　Finning would have an unexpected effect upon⑮ Peter Benchley，the man who wrote the book the film Jaws was based on⑯．[13] In 1980，Benchley was diving⑰ when[14] he came across⑱ an awful sight．It was an area where fishermen were finning，and the sea floor was covered with⑲ dead sharks[15]．Benchley saw sharks being killed and this caused a deep change in him．He came to see people as⑳ a danger to sharks，rather than㉑ the other way round㉒．From that day on㉓，he fought to protect sharks．He admitted that his book was wrong about sharks' behaviour[16]．“Sharks don't target㉔ humans，” he said．Experts have proved that sharks do not see people as food，and they attack us by mistake㉕[17]．Only around six people are killed by sharks every year． [13]本句是一个复合句。the man是Peter Benchley的同位语，其后who引导的定语从句，修饰先行词the man，而the book后为省略了关系代词that/which的定语从句，修饰先行词the book。 [14]本句句式为Sb．be doing sth．when...，其中when为并列连词。 [15]where fishermen were finning为定语从句，修饰先行词an area。 [16]that his book was wrong about sharks' behaviour为that引导的宾语从句，作admitted的宾语。 [17]that sharks do not see people...by mistake为that引导的宾语从句，作have proved的宾语。 Fortunately㉖，not everyone who watched the film Jaws became afraid of sharks[18]—some became interested in㉗ understanding them．Today，as we learn more about sharks[19]，more people than ever want to protect them from extinction㉘． [18]not everyone表示部分否定；who watched the film Jaws为定语从句，修饰先行词everyone。 [19]as we learn more about sharks是as引导的时间状语从句，as表示“随着”。 鲨鱼：危险动物 还是濒危动物？ 我们看到一个女人夜晚在漆黑的海水里游泳。突然，她被什么东西拖到了水下。她挣扎着露出水面，发出惊恐的尖叫，然后就彻底消失了。这是1975年上映的电影《大白鲨》的开场画面，呈现了鲨鱼攻击人类的一幕。电影讲述了一只大白鲨袭击并杀死游泳者的故事。《大白鲨》大获成功，吸引了大量观众并赢得了众多奖项。这部电影也加深了人们对大白鲨的固有印象：这是一种危险的动物。 人类本就害怕鲨鱼，而电影《大白鲨》加深了这种恶劣印象，让人们对鲨鱼，特别是大白鲨，心生恐惧。许多看过电影的人开始相信，鲨鱼是吃人的有害动物。由于害怕遇上电影里描绘的这种可怕生物，有些人再也不去海里游泳了。而另外一些人则开始无所顾忌地捕杀鲨鱼。当时，没人在意鲨鱼是否被杀，也没人在意杀了多少。人们认为鲨鱼死有余辜。 1975年之后，在美国附近海域里，大型鲨鱼的数量迅速下降，这一趋势很快蔓延到全球。这不仅仅是因为人类对鲨鱼的恐惧，还因为采割鱼鳍。采割鱼鳍是一种渔猎活动，人们捕到鲨鱼后将鱼鳍割下，鲨鱼被扔回海中缓慢而痛苦地死去，割下的鱼鳍用来做鱼翅汤。每年有数百万的鲨鱼因此丧命。 鱼鳍采割活动对《大白鲨》电影的原著作者彼得·本奇利产生了出乎意料的影响。1980年，本奇利在潜水的时候看到了可怕的一幕：渔民们正在这片海域采割鲨鱼的鱼鳍，海底遍布着鲨鱼的尸体。本奇利亲眼看见鲨鱼被杀，这引起了他内心的深刻转变。他意识到人类才是鲨鱼的威胁，而鲨鱼并非人类的敌人。从那天起，他开始为保护鲨鱼而努力。他承认自己书中对鲨鱼行为的描述是不正确的。“鲨鱼并不以人类为攻击目标。”他说。专家们也已经证明鲨鱼不会将人类视为食物，它们对人类的攻击都是无意的。每年因鲨鱼攻击致死的人数在六人左右。 幸运的是，并非每个看过《大白鲨》这部电影的人都变得害怕鲨鱼——有些人变得更有兴趣去了解它们。时至今日，随着我们对鲨鱼了解的加深，越来越多的人愿意去保护它们免遭灭绝。 1 / 1 学科网（北京）股份有限公司 $
