Presenters and recipients at the next Academy Awards would be advised to refrain from rambling thank-you and unentertaining political proclamations. 下一届奥斯卡颁奖典礼上,颁奖者和得奖者都将受到规劝:应避免拉拉杂杂的感谢词和乏味的政治宣言。
A refrain (from Vulgar Latin refringere, "to repeat", and later from Old French refraindre) is the line or lines that are repeated in music or in verse; the "chorus" of a song. Poetic fixed forms that feature refrains include the villanelle, the virelay, and the sestina.
