7、。人们总是害怕鲨鱼，但大白鲨使情况变得更糟。它使人们害怕鲨鱼，特别是大白鲨。许多看过这部电影的人开始相信鲨鱼是吃人的坏动物。有些人因为害怕电影里这个可怕的生物而停止在海里游泳。其他人开始捕捞鲨鱼，尽可能多地捕杀。那时，没有人关心鲨鱼是否被杀，或者有多少被杀。人们只想杀了它们。1975年后，大鲨鱼的数量在美国各地迅速下降，很快在全世界范围内下降。这不仅是因为对鲨鱼的害怕，而且是因为割鲨鱼鳍。割鲨鱼鳍是一种捕捉鲨鱼然后割掉鱼鳍的捕鱼方式。鲨鱼被扔回海里，在那里它们慢慢地、痛苦地死去。鱼鳍被用在鱼翅汤里。割鲨鱼鳍每年杀死数百万条鲨鱼。割鲨鱼鳍会对彼得本奇利产生意想不到的影响，电影大白鲨就是根据他写的
8、那本书改编的。1980年，本奇利正在潜水，这时他偶然看到一个可怕的景象。这是一个捕鱼者割鱼鳍的地方，海底布满了死去的鲨鱼。本奇利看到鲨鱼被杀，这给他内心带来了深刻的改变。与之前的观点相反，他开始把人看作是对鲨鱼的一种危险。从那天起，他为保护鲨鱼而奋斗。他承认他的书错怪了鲨鱼的行为。“鲨鱼不会以人类为目标，”他说。专家们已经证明，鲨鱼并不把人看作食物，他们错误地攻击了我们。每年只有大约6人被鲨鱼杀死。幸运的是，不是每个看过电影大白鲨的人都害怕鲨鱼，有些人变得对了解鲨鱼感兴趣。今天，随着我们对鲨鱼的了解越来越多，越来越多的人想保护它们免遭灭绝。课堂合作探究1scare v. 使(某人)惊恐，吓唬(
