— We often take part in after-class activities. I like to play _______ basketball, but my brother likes to play________ guitar.
Wake up, little darling, the birdies are out,
And here you are still in your nest!
The laziest birdie is hopping about;
You ought to be up with the rest.
Wake up, little darling, wake up!
Oh, see what you miss when you sleep so long
The dewdrops, the beautiful sky!
I can not sing half what you lose in my song;
And yet, not a word in reply.
Wake up, little darling, wake up!
I've sung myself quite out of patience with you,
While I bend o'er your dear head;
Now birdie has done all that birdie can do:
Her kisses will wake you instead!
