万圣节是西方传统节日。万圣节前夜，当夜幕降临，孩子们穿上五颜六色的化妆服，戴上千奇百怪的面具。有的披上漆黑长衫，骑着“魔帚”，扮作女巫；有的裹上白床单装鬼；有的戴上画有骷髅旗的帽子扮成海盗……

The Witches Caldron
by William Shakespeare

"Eye of newt, and toe of frog,
Wool of bat, and tongue of dog"
"Adder's fork, and blind-worm's sting,
Lizard's leg, and owlet's wing"

"For a charm of powerful trouble,
Like a hell-broth boil and babble"

"Double, double, toil and trouble,
Fire burn, and caldron bubble"
