我一定堅持到底用英語怎么說

我原來也是像回答這么認為的,后來到了國外才知道這種用法語法上沒錯但是國外根本沒人聽得懂. 給樓主一個常用的句子:
I will hold on to the last.

再給你幾個例句:
it ' s difficult , but i ' m going to persevere with it
難是難,但我一定堅持到底

it ' s difficult , but i ' m going to persevere with it
難是難,但我一定堅持到底

我一定堅持到底
英文：I'll stick it out。
或者：I must stick to it in the end。
堅持到底
英文：hold on to the last； carry through firmly (to the end)； hold on straight to the end；stay the course follow through
He knew he was in the wrong, but was determined to face it out.
他知道自己錯了, 卻決心堅持到底

回答和翻譯如下 ：

我一定堅持到底

I'll stick it out
