Question

　　 Sharks( 鲨鱼 ) are not as dangerous to humans as humans are to sharks. Even though millions of people swim in the seas each year fewer than fifty serious shark attacks appear usually and only ten of these are fatal ( 致命的 ). The reason for this low accident rate is that most sharks are afraid of living things as large as humans. Of the350 known kinds of sharks only one — the great white shark — is totally unafraid of humans. At the same time humans kill sharks in greater numbers than in the past. Thousands are hunted and killed each year for food ． Thousands more are killed by the nets under the water which are put off the beaches to protect swimmers in Australia and South Africa ． Even the great white shark is reducing as humans hunt it for its teeth which are sold to collectors. Maybe it is time we began worrying less about protecting people from sharks and more about protecting sharks from people.
