Question

9．Many views are held as to whether or not sharks will attack man．Some people believe that a shark will attack man only when he is near the shark in the water．Others take the opinion that sharks never attack man．The facts show that the truth is between these two opinions．
There are thirty-two kinds of sharks，and only three are dangerous to man．These are the hammer head shark，the tiger shark，and the white shark．All sharks are easily frightened and are much more afraid of ma n than man afraid of them．They have a keen sense of smell even from a place that is a fairly long way away．The smell of blood excites them，then they may attack human beings．
If such an attack does take place，however，it is done blindly（盲目地）because the shark happens to be excited by the smell of blood．This is very different from the manner in which a lion or a tiger will attack its victim（受害者）in the woods．The one acts without thinking while the other acts with the greatest care．
