Sharks: Dangerous or Endangered
1 We see a woman swimming at night in a dark sea. Suddenly, she is pulled underwater. She surfaces, cries in fear, then disappears forever. This is the opening scene from the 1975 film Jaws, 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-held idea of the great white shark as a dangerous animals.
v. come up to the surface of water
a. strong n. strength
in surprise in pain
a pity a danger a failure
2 People have always been scared of sharks, but Jaws made things worse. It made people frightened of sharks, especially of the great white shark. Many people who saw the film started to believe that sharks were bad animals that ate humans. Some people stopped swimming in the sea, afraid of the horrible creature from the film. Other people started fishing for sharks, 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.
To make things worse, it began to rain.

see the kite blown away; find the house broken into
3 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 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.

4 Finning 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. 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.

say to interrupt the lecturer politely.
A polite interruption is usually framed as a request for permission to interrupt someone, often starting with If…, May I… or Can I… This may be preceded with an apology such as Sorry, … or Excuse me, … Usually we interrupt someone when they pause for breath, or during the slight pause between spoken clauses.
