The Peony’s Whisper
Emily Dickinson
A peony buds in secret air-
Its hues are shy to meet the sun-
But when the light unclasps its hair-
The garden trembles-one by one.
Its petals, like a whispered vow,
Unfold in velvet silence deep-
The wind, that paused to watch it now,
Steals half its fragrance as it sleeps.
《牡丹的私語》
一株牡丹在隱秘的空氣中抽芽—
它的色彩羞于直面陽光—
但當光線解開它的發綹—
花園便一瓣接一瓣地戰栗。
它的花瓣，如一句低語的誓言，
在天鵝絨般的寂靜中舒展—
風、曾駐足凝望此刻的它，
卻在它沉睡時，偷走了半縷芬芳。
4c
Make your poster.
The most beautiful flower-Peonies
Do you know peonies They have big, round flowers. They come in pink, red, white... even yellow! Their petals are soft like silk. In China, we call them the “Queen of Flowers”. And they are called “National Flower”.
People grow peonies in gardens for over 1,000 years! In ancient stories, peonies stand for happiness and good luck. Artists love painting them, and you can see peony pictures on cups, clothes, and even buildings! When spring comes, peonies bloom. Their sweet smell makes people happy. Next time you see a peony, say “Hi, Queen!” to it!
