One day， a man was walking by the corner of a street． Here he met（1） 　　little boy holding a bird cage and selling the birds inside． He（2） 　　（stop） and looked very sadly at the birds without freedom in front of him． The birds were screaming in the cage， trying to fly away．

After standing（3） 　　a moment，he said to the boy，"How much does（4） 　　（you） bird cost？ I want…"

"One fifty cents， sir，" the boy answered quickly．

"I am afraid that you are mistaken． I am not asking how much it is．"The man said，"I would like（5） 　　（buy） all of them． What I ask is how much you want for them．"

Hearing this， the boy（6） 　　（happy） counted the number of the birds in the cage．

"They cost five dollars．"

"Here（7） 　　（be） the money! "The man passed the money． The boy counted excitedly． However， he then was（8） 　　（surprise） to find all the birds had flown away．

"OH， my god， for what reason did you do that， sir？ You don't even get a bird!" The boy asked the man who set the birds free．

"My boy， let me tell you（9） 　　I did this． " The man said， "I have no right to get them．Every life should be free and they are our（10） 　　（friend） So we should give them freedom．"
