7．
Every evening Sylvie left her grandmother's house at 5：30to bring their cow home．The old animal spent her days out in the open country eating sweet grass．When the cow heard Sylvie's voice calling her，she would hide among the bushes，unwilling to go home．
This evening it had taken Sylvie longer than usual to find her cow．The child hurried the cow through the dark forest，following a narrow path that led to her grandmother's home．"Hello，little girl，"a young man called out cheerfully．"I've been hunting for birds，but I've lost my way．"The young man explained he was a scientist，who searched for birds．"Do you put them in a cage？"Sylvie asked．"No，"he answered，"I shoot them and deal with them with special chemicals to preserve them，"
"I saw a white heron（苍鹭）not far from here two days ago．It's a very rare bird．Have you seen it，too？"he asked Sylvie．Sylvie's heart began to beat fast．She knew that strange white bird!The young man was staring at Sylvie．"I would give﹩10to the person who showed me where the white heron is．"
Sylvie had a plan that she would get the﹩10for her grandmother and make the young man happy．Her plan was to climb to the top of a tall pine tree to see where the white heron had hidden its nest．
The pine tree seemed to grow taller，the higher that Sylvie climbed Suddenly a bird with broad white wings flew past Sylvie and landed on a pine branch below her．The white heron sat on its nest in a nearby tree．Sylvie gave a long sigh．She knew the wild bird's secret now．Slowly she began her dangerous trip down the ancient pine tree．
About an hour later Sylvie returned．Both her grandmother and the young man stood up as she came into the kitchen．The splendid moment to speak about her secret had come．But Sylvie was silent．She could not tell the heron's secret and give its life away．
