4. 在星空下，遥远的西方也传来了歌谣，一起来欣赏一下吧！
Twinkle, twinkle, little star
How I wonder what you are
Up above the world so high
Like a diamond in the sky
When the blazing sun is gone
When he nothing shines upon
Then you show your little light
Twinkle, twinkle, all the night
Then the traveller in the dark
Thanks you for your tiny spark
He could not see which way to go
If you did not twinkle so
In the dark blue sky you keep
And often thro' my curtains peep
For you never shut your eye
Till the sun is in the sky
As your bright and tiny spark
Lights the traveller in the dark
Though I know not what you are
Twinkle, twinkle, little star
