我冇盡到我ge責任..英文講法''

點解搞到咁複雜既. 用一句,

i did not give my effort 就得啦. (點解用 did - 過去式, 因為是你以前沒有進過責任. 不是現在)

你既英文真係有很大的進步空間. 真的不知道你說什麼. 我相信你用字典照譯. 要搞到我用字典查你個 exert 點解.

其實學多些英文就自自然然識架啦. 我諗你一定冇咁做. 對吧?

It's my duty. I'm accountable for that. 這是我的責任，是我該做的
I did not do my best.　我沒有盡力做好．
I have not tried made my best endeavour to do this.　我沒有嘗試用我最大努力去做

I never exert my blame. - I don't understand what it means

I did not blame you though. （不過我沒有責怪你）

i regret i did not take my part

I never exert my blame~~~唔明你既意思
