People are scared of some types of animals. For example, snakes, bears, spiders and wasps frighten people because they have thepotential to kill. When people go swimming in the ocean, they often get scared of sharks.
 They think sharks will suddenly appear andattack. But the reason for this fear is mainly due to wrong information and movies about killer sharks. The truth is shark attacks onpeople are very rare.There are about two hundred and fifty different species of sharks. The smallest ones are thirty centimeters long and the largest cangrow up to fifteen meters long. Of all the different species of sharks, only about twenty have been known to attack people. Mostsharks just live in the ocean like other fish. Sharks have a very good sense of smell. They are also good at sensing splashing and other disturbances in the water. Sharks use thesesenses to hunt fish and birds that are already hurt. For this reason, they are often called the cleaners of the ocean. For example, a birdwith a broken wing that splashes helplessly in the ocean may be attracted by a shark and be eaten. Sometimes when people go swimming they splash in a way that is unnatural for animals in the ocean. The splashing makes themsound like a hurt animal and that is why a shark might attack. By attacking a person, a shark isn’t cruel. It is only doing what itsinstincts tell it: to clean the ocean of hurt animals. In fact, sharks should be very scared of people. We use their skin for leather and their fins for soup. Some people even go hunting andkilling large sharks, so they can show everyone how brave they are. So who is really cruel, the sharks or people? But if you’re stillscared, there is an easy solution. Just stay out of the water. wasp 大黃蜂 frighten 使害怕 potential 潛力 attack 攻擊 due to 由於 rare 稀有的 species 種類 sense 感覺 splash 濺起disturbance 擾亂 cruel 殘酷的 instinct 本能 leather 皮革 fin 魚鰭 solution 解決方法
