I always like to work on leftovers, doing the leftover things. 我一向喜歡那剩余的東西來創作，做剩余物的作品。
The National Renewable Energy Lab has a plant that converts harvest leftovers and just about anything else into fuel. 國家可再生能源實驗室有一個工廠，專門轉換收割后的剩余物或者任何其他物質為燃料。
He brewed a pot of soup from the leftovers. 他用殘羹剩菜煮了一鍋湯。
