Ｓｈａｒｋｓ ａｎｄ Ｃｒｏｃｏｄｉｌｅｓ

One day I went to swim with my friends in the sea near the mouth of a river．When we got there，I asked a boy fishing nearby：“Are there any sharks here?”

“No，”he answered．

My friends and I went into the river．I still felt unsafe and came out of the water a few minutes later to ask the boy again，“Are you sure there are no sharks here?”

“There are no sharks here because they are afraid of crocodiles here．”said the boy．
