Twinkle,twinkle
Twinkle,twinkle little star.
How I wonder what you are.
Up above the world so high,Like a diamond in the sky.
When the bright,hot Sun has gone,
When the day has ended and the night has begun,
Then you shine your little light,And twinkle,twinkle all the night.
On a starry night
On a sarry night
The stars twinkle
Like thousands of bright eyes
Watching us and winking.
On a cloudy night
The stars are hidden As if they have closed their eyes.
