Baa baa black sheep, have you any wool?
Yes sir, yes sir, three bags full!
One for the master, one for the dame,
And one for the little boy who lives down the lane.
Baa/bæ, bɑ/羊叫声
dame/deɪm/女士(拉丁语domina)
“black sheep”,害群之马,可能源自18世纪的一句谚语: "There is a black sheep in every flock" 指的是每群白羊中必有一只黑色,不值钱,而且黑色不祥(black sheep had wool that could not be dyed and was thus worthless...)
