   Sam and Mike worked in the same office and they were friendly to each other. They often took their holidays together. Last summer the two young men went to a city by the sea for their holiday. They visited a few places of interest, swam in the sea and then lay on the sands or went out for walk after supper. They had a good time there.

   But one day, when they were swimming, a shark swam to Sam and pulled the poor young man to the bottom(海底).Mike heard him calling for help and swam towards him in a hurry, but it was too late. The shark had swallowed(吞)Sam. Mike was very sad and returned to his city alone. In the train, he thought hard. Sam’s mother had a heart disease(心脏病). He didn’t know how to tell her about the bad news. At last he found a way. He asked his friend Robert who worked in a hospital to go here with him.

  “Bad news for you, Mrs Smith ,”said the young man. “Sam’s swimming suit was swallowed by a shark.”

   “It doesn’t matter, ”said the woman, “ I can buy a new one for him. But where was he at that moment?”

   “He was in his swimming suit!”
