Summarizing and paraphrasing

Summarizing
-Many people are feared by the sharks when they swim in the open ocean.
However, actually many sharks don't attack you.
There are more accidents by stucking the lightening or drowning!
If you are still worried by the sharks, there are several ways to prevent you from the shark attacks.
Traveling in groups can reduce the attaking of sharks.
Because sharks like the solitary swimmer.
Also, When you have a cut in body, don't go into the ocean since sharks have a good sense of smell

Paraphrasing
--original one :Traveling in groups is one way to reduce the chances.Bears are very unlikely to attack groups of four or more people.Also, stay calm if you ran into a bear. Bears are much more likelt to attack if you try to run away.
