     Mr. Zhang was a sports fan. He worked in a hospital in the capital. He was busy all the time and had little

time to have a rest. And one day he felt unwell and couldn't go on working. He decided to spend a week's

holiday in a quiet village where he could go swimming or fishing. He got off at a small railway station and

soon got to a quiet village. He took a room hotel and went to sleep as soon as he had a good meal.

     At first Mr. Zhang enjoyed himself there. He could do everything he wanted and went wherever he liked.

Nobody disturbed him and knocked at the door at midnight. But on the fourth day he was in trouble. After

lunch it was very hot. He went swimming in the river. Suddenly he saw a beautiful bird in a big tree. He

wanted to catch it, so he walked to it, but it found him and flew away as soon as gone. He began to pick

some flowers in the forest and before long he lost his way.

     The sun had gone down and night had fallen before Mr. Zhang found a small restaurant in another village.

He came in and told them to bring him some bread, two eggs and a glass of tea. After a while his food was

brought. Soon he ate up all the bread and eggs. When he was going to have the tea, he found there was a fly

in the glass.

     "What's in my tea?" Mr. Zhang called out, " A fly." 

     "It's impossible, sir." said the owner of the restaurant, "I had told them to pick all the flies out of your tea

before they brought it to you!"
