Many people have the impression (印象) that sharks are man-eating monsters (怪兽) that pull swimmers down to eat them. This is far from the truth, however, and has largely been made by Hollywood movie producers who use this false image to add the feeling of fear and danger to their movies.
In fact, many sharks will only feed on already dead animals. Some, like the huge whale shark, have no teeth and are harmless to nearly everything. Out of over 470 kinds of sharks, only some will attack (攻击) humans: the great white shark, oceanic whitetip shark, tiger shark, and bull shark. These kinds of huge and powerful sharks can cause serious injuries. However, these usually avoid humans as we are not a part of their natural diet. In most cases of shark attacks, the shark mistakes a human for marine mammal (海洋哺乳动物). After taking a bite (咬)，it usually will soon know its mistake and stop attacking a human. The number of shark attacks every year is about four, and if you compare this to the number of sharks killed each year by humans over a hundred million —it's the sharks who should be scared of us, not the other way around.
More than 600 people die every every year from snake bite in Sri Lanka alone. Falling fruits kill about 150 people every year, and about 40,000 Americans die each year in car accidents. Experts even say that you are far more likely to die from a bee than a shark attack.
So what does this mean? Like all dangerous animals, sharks must be well treated, but in fact, they are nothing like the killing machines that they are made out to be in the movies. Sharks are amazing animal. They've been around for over 420 million years, and they have excellent problem-solving skills. It's time we stop seeing sharks as sea monsters.
