12、ple。7that ate humans为定语从句修饰先行词animals。8killing as many as they could为现在分词短语作结果状语。9wanted them killed为动词后加复合宾语，过去分词killed作宾补。After 1975，the number of large sharks around America fell quickly，and soon fell around the world.This was not only due to fear of sharks，but also finning10Finning is a type of

13、fishing where sharks are caught and their fins cut off.11 The sharks are thrown back into the sea where they die slowly and painfully.The fins are used in shark fin soup.Finning kills millions of sharks a year.10本句含有not onlybut also意为“不仅，而且”，连接两个并列成分。11本句中动名词finning作主语，谓语动词用单数形式；where sharks are cau

14、ght为定语从句修饰a type of fishing。Finning would have an unexpected effect upon Peter Benchley，the man who wrote the book the film Jaws was based on.12 In 1980，Benchley was diving when13 he came across an awful sight.It was an area where fishermen were finning，and the sea floor was covered with dead sharks

16、ave proved that sharks do not see people as food，and they attack us by mistake16Only around six people are killed by sharks every year.12本句为复合句。the man与Peter Benchley为同位语，其后who引导的定语从句修饰先行词the man，而the book后为省略关系代词that/which的定语从句，修饰先行词the book。13本句句式为be doing sth.when，其中when为并列连词。14where fishermen we

18、learn more about sharks18，more people than ever want to protect them from extinction.17not everyone表示部分否定；who watched the film Jaws为定语从句修饰先行词everyone。18as we learn more about sharks是as引导的时间状语从句，as表示“随着”。译文参考鲨鱼：危险还是濒危？我们看到一个女人晚上在漆黑的海里游泳。突然，她被拖到了水下。她浮出了水面，恐惧地大哭，然后永远消失了。这是1975年上映的电影大白鲨的开始场景，展示了鲨鱼的攻击。它讲

19、述了一条大白鲨袭击并杀死游泳者的故事。大白鲨获得了巨大的成功，吸引了大批观众，赢得了许多奖项。它强化了人们长期持有的观念，即大白鲨是一种危险的动物。虽然人们一直都害怕鲨鱼，但大白鲨让事态变得更为严重。它使人们恐惧鲨鱼，尤其是大白鲨。许多看过这部电影的人开始相信鲨鱼是吃人的坏动物。一些人停止在海里游泳，因为害怕遇到电影里描写的这种可怕的动物。其他人开始捕捞鲨鱼，尽可能地捕杀鲨鱼。那时，没有人关心鲨鱼是否被杀死，或者有多少被杀死。人们只是想杀了它们。1975年以后，美国各地的大鲨鱼数量迅速下降，不久世界各地的大鲨鱼数量也随之下降。这不仅是因为人们对鲨鱼的恐惧，还因为割鳍。割鳍是一种捕鱼方式，在这种

20、捕鱼方式中，鲨鱼被捕获后，它们的鳍被割掉。然后鲨鱼被扔回海里，在那里它们缓慢而痛苦地死去。鱼鳍用于做鱼翅汤。割鳍每年害死数百万条鲨鱼。割鳍可能对彼得本奇利产生了意想不到的影响。此人写了大白鲨，电影大白鲨就是以该书为蓝本。在1980年，本奇利潜水时遇到了一个可怕的景象。这是一个渔民正在割鳍的地方，海底布满了死去的鲨鱼，这使他产生了深刻的变化。他开始认为人类对鲨鱼是一种威胁，而不是鲨鱼对人类是威胁。从那天起，他就开始保护鲨鱼。他承认他的书中关于鲨鱼行为的描述是错误的。“鲨鱼不以人类为攻击的目标，”他说。专家们已经证明，鲨鱼并不把人当作食物，它们不过是误袭我们。每年只有大约六人被鲨鱼咬死。幸运的是，并不是所有看过电影大白鲨的人都害怕鲨鱼有些人对了解鲨鱼很感兴趣。今天，随着我们对鲨鱼了解得越来越多，越来越多的人想要保护它们免于灭绝。
