day也可表示“工作日”,指一天二十四小時之內(nèi)的工作時間,是可數(shù)名詞。
day還可作“時期; 時代; 壽命”解,常用復(fù)數(shù)形式,若用單數(shù)常須與my, their等物主代詞連用。
day還有“全盛時期,黃金時代”的意思,是單數(shù)名詞,不用于復(fù)數(shù)形式。

day and night和night and day,有的詞典認為兩者意思有些不同:day and night等于continuously,用于以晝?yōu)橹鞯膱龊? night and day等于always,用于以夜為主的場合,實際上,兩者現(xiàn)已無區(qū)別地使用,都是“日夜不停地,日日夜夜地”的意思。
the day before yesterday(前天), the day after tomorrow(后天)等這些短語里的the在美式英語中可以省略。例如:He left for London (the) day before yesterday.他前天啟程去倫敦了。
