恐怕这事我干不了 i'm not sure ican do it

以致于什么也干不了 I can get nothing done

不干了 call it quits ; bow out ; Do not like the ; cingl it quits

我不干了 I quit ; allora mollo

你干的事瞒不了我 I Saw What You Did

洗手不干了 wash one's hands of something ; Wash your hands of something

不想干了 Did not want to do ; Don't want to do

撂挑子不干了 to hang up one's boots

河里的水也不干净了 River water is not clean
