As what we explained in the last answer, 又(yòu) means the repetition of the same type of action or situation. It is mainly used to show the action or event already happened again, but can also be used in the future tense. For example,
1)明天又是工作日
Míngtiān yòu shì gōngzuòrì
Tomorrow again is weekday
‘Tomorrow is weekday again.’
2) 看来他又要生气
Kànlái tā yòu yào shēngqì
Seemingly he again will be angry
‘It seems that he will be angry again.’
3) 我明天可能又不得不请假
Wǒ míngtiān kěnéng yòu bùdébù qǐngjià
I tomorrow maybe again have to ask for a leave
‘I probably have to ask for a leave again tomorrow.’
