Is there any mistake in this passage SHARKS IN DANDER Many of us think that sharks are dangerous animals that always attack and kill people.The truth is,you are more likely to be hit by lightning than br htitten by a shark.In fact,people kill millions of sharks every year.They may use shark skin to make leather or use other body parts to make medicine.But the main reason sharks are killed is that people want their fins.Shark fin soup is an expensive delicacy in Chinese restaurants. Usually people get fins by cutting them right off the shark--often when it is still alive.This is called "finning".Then they throw the shark back into the water.Because it cannot swim with fins,the sharks dies.Divers have found many dead sharks without fins at the bottom of the ocean. It takes many years before sharks are old enough to have babies.When they do have babies ,they have very few of them at one time.This is why some experts think sharks may be ectinct in 10 or 20 years if people keepkilling them.
