同学你好~
The bird in the cage
There is a smart bird , which lived in the cage. 时态统一，lived改成lives
Someone says that the bird always sing song happily . but I think it must be not to sing song.
sings单三形式，句号改成逗号，but I don't think it is always singing. 这样表达
I hope that the bird in the cage can free, I want to see it fly in the sky pleasure.
can be free，free是形容词。逗号改成句号。pleasure改成happily 副词

祝同学学习进步~
