我一定坚持到底用英语怎么说

我原来也是像回答这么认为的,后来到了国外才知道这种用法语法上没错但是国外根本没人听得懂. 给楼主一个常用的句子:
I will hold on to the last.

再给你几个例句:
it ' s difficult , but i ' m going to persevere with it
难是难,但我一定坚持到底

it ' s difficult , but i ' m going to persevere with it
难是难,但我一定坚持到底

我一定坚持到底
英文：I'll stick it out。
或者：I must stick to it in the end。
坚持到底
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.
他知道自己错了, 却决心坚持到底

回答和翻译如下 ：

我一定坚持到底

I'll stick it out

I must insist in the end

I would try my best.
I will never give up.
