（3）Some people think that all wild animals are dangerous．In fact very few of them will attack a man if he leaves them alone．When you meet a lion or an elephant，you should run away．But even a lion will avoid a man unless it is very hungry．Lions and tigers only kill and eat men when they have grown too old to catch their usual food．Some animals get frightened if they only smell a man．Some stand and look at him for a while before they run away．Some take no notice at all but quickly walk in another direction．Wild animals only attack a man when they think that he means to hurt their babies，or when they are shot at and get angry．
