We see a wman swimming at night in a dark sea. Suddenly, she is pulled underwater. She surfaces, cries in fear, then disappears frever. This is the pening scene frm the 1975 film Jaws, shwing a shark attack. It tells the stry f a great white shark that attacks and kills swimmers. Jaws was a great success, attracting huge audiences and winning many awards. It strengthened peple’s lng-held idea f the great white shark as a dangerus animal.
Peple have always been scared f sharks, but Jaws made things wrse. It made peple frightened f sharks, especially f the great white shark. Many peple wh saw the film started t believe that sharks were bad animals that ate humans. Sme peple stpped swimming in the sea, afraid f the hrrible creature frm the film. Other peple started fishing fr sharks, killing as many as they culd. At that time, nbdy cared if sharks were killed, r hw many were killed. Peple just wanted them killed.
After 1975, the number f large sharks arund America fell quickly, and sn fell arund the wrld. This was nt nly due t fear f sharks, but als finning. Finning is a type f fishing where sharks are caught and their fins cut ff. The sharks are thrwn back int the sea where they die slwly and painfully. The fins are used in shark fin sup. Finning kills millins f sharks a year.
Finning wuld have an unexpected effect upn Peter Benchley, the man wh wrte the bk the film Jaws was based n. In 1980, Benchley was diving when he came acrss an awful sight, It was an area where fishermen were finning, and the sea flr was cvered with dead sharks. Benchley saw sharks being killed and this caused a deep change in him.
He came t see peple as a danger t sharks, rather than the ther way rund. Frm that day n, he fught t prtect sharks. He admitted that his bk was wrng abut sharks’ behaviur.“Sharks dn’t target humans,”he said. Experts have prved that sharks d nt see peple as fd, and they attack us by mistake. Only arund six peple are killed by sharks every year.
Frtunately, nt everyne wh watched the film Jaws became afraid f sharks - sme became interested in understanding them. Tday, as we learn mre abut sharks, mre peple than ever want t prtect them frm extinctin.

Think & Share
1 Hw d yu think Peter Benchley felt after diving in 1980?
He might feel sad fr the sharks being killed; he might feel regretful fr depicting the great white shark as a dangerus animal in his bk; he might als feel angry abut finning.
2 What ther films r bks d yu knw that feature wild animals? D they “paint”a gd r bad picture f these animals? Say hw the animals are described.
A film—March f the Penguins（《帝企鹅日记》）. It“paints”a gd picture f penguins. This is a film that really reflects the life f the penguins. The climate f the nrth f the Antarctic cntinent is mild and the fd is adequate; while the suth is cvered with snw, the climate is cld and the fd is shrt. But the suthern part has its advantages. There is n natural enemy. In rder fr the penguins t grw up healthily, the penguins’ parents are cming frm the nrth t the suth t hatch the little penguin eggs every year. The penguins’ parents take turns t wrk fr hatching eggs and lking fr fd. Hw hard we can imagine the weak penguins are ding these tasks every year.
A bk—My Wild Animal Friend（《我的野生动物朋友》）. It“paints”a gd picture f many wild animals in Africa. It tells the mving stry and persnal experience f Tippi Degre when she returns t Paris at the age f 10. At the same time, mre than 130 rare pictures taken by her parents，the famus wildlife phtgraphers, are included, which can nt nly be appreciated，but als aruse peple’s awareness f prtecting natural wildlife.
