英语翻译

I'm sorry my English is not very good, but I was very young, I am confident that I can quickly learn English well, because if I think a thing which is worth me to do, I can do, I have to achieve this goaldetermination, so I will work hard to learn more things to enrich myyourself, and learn in order to practise
望采纳!为什么要在I have to achieve this后面加goaldetermination，能告诉我什么意思么，谢谢是 goaldetermination 目标的决心的意思
