SHARKS: DANGEROUS OR ENDANGERED
We see a woman swimming at night in a dark sea. Suddenly, she is pulled underwater①. She surfaces②， cries in fear, then disappears forever. This is the opening scene from the 1975 film Jaws, [1]showing a shark attack．It tells the story of a great white shark that attacks and kills swimmers. Jaws was a great success, attracting huge audiences and winning many awards.It strengthened people's long-held③ idea of the great white shark as a dangerous animal.
[1]动词-ing短语作定语，可改写为定语从句which shows a shark attack。
①underwater adv.在水面下
②surface vi.升到水面，

People have always been scared④ of sharks, but Jaws [2]made things worse．It made people frightened of sharks, especially of the great white shark.[3]Many people who saw the film started to believe that sharks were bad animals that ate humans.Some people stopped swimming in the sea, [4]afraid of the horrible creature from the film. Other people started fishing for sharks, [5]killing as many as they could．At that time, nobody cared if sharks were killed, or how many were killed. People just wanted them killed.
④scare v．使(某人)
惊恐，吓唬
After 1975，the number of large sharks around America fell quickly, and soon fell around the world.This was not only due to⑤ fear of sharks, but also finning⑥.Finning is a type of fishing [6]where sharks are caught and their fins cut off⑦．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.

⑤due to 由于，因为
⑥fin v．切去(鱼的)鳍
n．鱼鳍
⑦cut off切掉；被隔绝；
切断(供给)；中断

Benchley [8]saw sharks being killed and this caused a deep change in him. He came to see people as a danger to sharks, rather than⑨ the other way round⑩.

Notes
2. In 1980, Benchley was diving when he came across an awful sight.
句中的when是并列连词，意为“就在这/那时”，相当于and then或and
at the same time。
e.g. I was thinking of this when I heard my name called.
我正想着这件事，突然听到有人叫我的名字。
when作并列连词时常用于以下句型中：
be doing … when … 正在做……这时……
be about to do … when …= be on the point of doing … when … 正在做……这时……
had just done … when … 刚做了……这时……
Notes
3. Fortunately, not everyone who watched the film Jaws became afraid of sharks—
some became interested in understanding them.
本句中not everyone是部分否定，意为“不是每个人”。
e.g. I hate to disillusion you, but not everyone is as honest as you.
我实在不愿把实情告诉你，但并非人人都像你那样诚实。
(1)英语中的all, both, each, every, everybody, everything, completely, whole, entirely等具有总括意义的代词、形容词和副词与否定词not连用，无论not位置如何，均构成部分否定，表示“并非都”的意思。
(2)若表示完全否定，可借助于no, none, no one, nobody, nothing, neither, never等。
