B1 日复一日，每天
repeatedly, every day
The same problems keep coming up day after day. 同样的问题每天都要出现。
Day after day, he's out there, walking the streets and knocking on doors.
And so it went, day after day, till we could bear no more.
It's the same excuses day after day. When will he take responsibility for his actions?
The same grim pattern is repeated day after day.
You read the same newspaper headlines day after day.
