not know the time of day 一问三不知
分类: 实用英语
“一问三不知”,指怎么问都不知道(say "I don't know" to every question),很糊涂或很无知。可以翻译为“be entirely ignorant; not know a thing”。与英文惯用语“not know the time of day”意思相近,表示“to be completely unintelligent, daft, or not alert”。
例句:
别问他了,他总是一问三不知。
Don't ask him any questions. He never knows the time of day.
