There are nearly 400 different types of sharks, but only about 30 types have even been reported as attacking human beings.
The chances of being attacked by a shark are very small compared to other dangers. Many more people drown（溺死）in the ocean every year than are bitten by sharks. The low number of attacks that happen every year proves that sharks do not feed on humans if they have the choice. There are three types of shark attacks. The main one is known as a ‘hit and run’. The shark attacks because it thinks you are a fish, but when it tastes a human it decides not to eat you. The second type is called a ‘bump and bite’. The shark bumps you to find out if you are fit to be eaten and then bites you if it thinks you are. The third type is called a ‘sneak’. When attacking in this way, the shark waits for you to swim by and attacks you suddenly. The latter（后者的）two types of attack are more likely to be deadly for humans.
However, your chances of being attacked by a shark can be reduced if you follow the advice below.
Do not swim in the dark. Sharks can still see you but you cannot see them.
Do not swim if you are cut or if you have a fresh wound. Sharks can smell blood over a long distance.
Do not wear bright clothing or jewellery because sharks are attracted to colours and shiny objects.
Try and stay in groups, as sharks usually avoid large numbers of people.
Don’t be frightened（受惊吓）by sharks as there is 30 times greater chance of being hit by lightning than being attacked by a shark.
【小题1】Are there only 30 types of sharks in the world?
【小题2】Are the chances of being attacked by a shark small or big compared to other dangers?
【小题3】What are the two deadly shark attacks called?
【小题4】Why should you try and stay in groups to avoid the shark attack?
【小题5】What does the writer mainly tell us in the passage?

Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks (攻击) suggests that sharks don’t like the way humans taste! In fact, most people who are attacked by the shark are still alive after receiving only one bite (咬). Why is this?
There are many opinions to explain why sharks sometimes attack people. One opinion is that sharks are just curious (好奇的). We know that sharks are the strongest animals in their environment, so they are not afraid of anything. Naturally, that means they are curious when they meet something unusual. Because they don’t have hands or feet., the only way they can find out an object is to bite it! It is thought that sharks sometimes bite humans for this reason, and then swim away.
Scientists also say that sharks would not waste energy trying to eat a human, as we have a lot of bones (骨头). It is hard for a shark to eat us because sharks don’t have hands, and they can’t pull the meat off our bones. Maybe that’s why they only bite us once. Unluckily, one bite from a large shark is serious enough to hurt people greatly!
Another opinion is that sharks attack humans by mistake. Some sharks may sometimes mistake humans for a seal. An example of this is when a shark attack attacks a surfer. A surfer lying on a surfboard looks like a seal when seen from below. Sharks like seals because they have thick fat.
Whatever the reason for shark attacks on humans, sharks should be afraid of us. Sadly, we kill almost 40 million of them each year.

Mike and Dick work in the same office. They don’t like the cold weather. And one day they decided to take their holiday in Australia. Their plane arrived in Sydney at nine in the morning. They had a good rest in a hotel. The next morning they rented(租) a car in the city and began their travel. A few hours later the sun was shining in the sky and there were no shade trees(遮阴树) beside the road. It was so hot that they could hardly go on driving. They had to stop to look around. Mike found a river was about half a kilometer away from them. They were both very happy and drove the car quickly. Soon they got to the river. Before they jumped into the water, Dick saw a boy playing under a big tree. He asked,“Are there any sharks(鲨) in the river, boy?”“No, there aren’t,”answered the boy. So they began to swim in the river. After a while, Dick felt something hit against his leg. He told Mike about it. They were afraid and stopped swimming. Dick asked loudly,“Is it true that there aren’t any sharks in the river?”“Yes, sir,”said the boy,“there’re a lot of crocodiles(鳄鱼) in the water. All the sharks have swum away!”
