Most sharks are dangerous. The largest kind of sharks-the whale shark-has small teeth and is quite harmless
to people. However, blue sharks, tiger sharks, white sharks and hammerheads are enemies of man. Man-eaters
are always a danger to swimmers in shark waters. Sometimes, though, men have used strange methods when
they're suddenly faced with a shark.
During world War Ⅱ, soldiers and sailors whose boats or planes were destroyed drifted (漂流) helplessly
on the ocean in small rafts (筏子). While waiting to be saved, the men had to struggle to stay alive and were
often attacked by sharks. In some cases, they had few weapons to protect themselves with. They found that
just splashing (溅水) water seemed to help keep the sharks away.
One sailor was swimming for his life in the Atlantic Ocean after his boat had been blown up. He saw a
shark swimming towards him. He hit the shark with his bare fist, and that drove it off.
Once, in Australia, a fisherman was fishing after sunset. He hooked a big fish and drew it towards the shore. His line broke when the fish was only a few yards from the shore. The fisherman waded (涉水) into the water
to try to catch it with his hands. In the dim light, it looked like the kind of fish that could be dealt with without
danger.
He put his arms around the fish and wrestled with it. Dragging it to the beach turned out to be harder than
he had expected, but at last he pulled it in. When he turned a light on it, he was amazed. He had caught a shark.
It was small for a shark, but it was the man-eating type and was about as long as a tall man. In a word, the
best way to deal with sharks is to keep far away from them.
