(略读，找主旨)
略读，顾名思义，就是粗略地阅读。略读的目的不在于精确地理解文章，而是为了了解大致内容，比如文章的主旨大意，传达的主要信息或作者的基本观点。当我们在有限的时间内要读完大量的文字时，通常采用略读的方式。一般来说，略读的速度比普通阅读速度快3到4倍。高考阅读文章讲述主要观点之后通常会有for example来佐证，如果看懂了主要观点，那么对示例所用的时间和精力就不需要太多了。

The third paragraph
3After 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 finning. Finning is a type of fishing (where sharks are caught and their fins cut off). 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.

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。采割鱼鳍是一种捕猎活动，人们捞到鲨鱼后将其鱼鳍割下，鲨鱼被扔回海里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。

The fourth paragraph
4Finning would have an unexpected effect upon Peter Benchley, the man who wrote the book the film Jaws was based on. In 1980, Benchley was diving when he came across an awful sight. It was an area (where fishermen were finning, and the sea floor was covered with dead sharks). Benchley saw sharks being killed and this caused a deep change in him.

鱼鳍采割活动对《大白鲨》电影的原著作者——彼得·本奇利产生了意想不到的影响。1980年，本奇利在潜水时看到了可怕的一幕：渔民们正在这片海域采割鲨鱼的鱼鳍，海底遍布了死去的鲨鱼。本奇利亲眼目睹鲨鱼被杀，这引起了他内心的深刻转变。
He came to see people as a danger to sharks, rather than the other way round. From that day on, he fought to protect sharks. He admitted that his book was wrong about sharks’ behaviour. “Sharks don’t target humans,” he said. Experts have proved (that sharks do not see people as food, and they attack us by mistake). Only around six people are killed by sharks every year.

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。他承认自己书中关于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。专家们也已经证明了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。
