我想买一个新床单。 I want to buy a new bed linen.
床单的中间部分磨薄了。 The sheets have worn thin in the middle.
羽绒被一种经常有可换洗被罩的被子,可以用来代替被褥或床单 A quilt, usually with a washable cover, that may be used in place of a bedspread and top sheet.
把床单好好泡一泡. Give the sheets a good soak.
我们把床单搓成绳子, 援绳下坠逃跑了. We twisted the bed sheets into a rope and escaped by climbing down it.
