这个问题是见仁见智的. 我认为前半句的意思是:经验分为两类,一是前人的经验,一是自己的经验.而学习就是经验的获得过程.后半句是说才能是靠刻苦的学习得来的,而这个过程是漫长且艰苦的,需要坚忍的毅力.

experience 可不可以作动词？

完全可以

Experience a great adventure; experienced loneliness.
经历一次伟大的冒险；体验寂寞

by experience是什么意思？？

by experience
基本翻译
adj. 凭经验
网络释义
learning by experience:从经验中学习|验中学
Taught by Experience:记取教训
ordinary minds, by experience:聪明人循理智办事，平常人照经验办事，蠢人按需要办事，畜生凭本能办事。

翻译my great experience

my great experience
是我丰富的阅历的意思
experience既有经历的意思也有经验的意思,具体应该结合上下文.
单就这个词来说,如果是翻译为我丰富的经验,会显的很不谦虚.
所以我认为应该更侧重于经历
2楼,您说的是一个句子,而my great experience是一个词,不太合适.

提问者,您的问题补充：跟一篇文章
是让围绕my great experience写一篇文章吗?
I went to cinema on the evening last Saturday.On my way there ,I saw a little girl was knocked down by a car .The car run away without stopping,so I thought I must send her to a huspital to save her life.
Without more thinking,I took a TAXI to the nearest hospital with the girl .When we got to the hospital ,I sent her to the emergency immediately.I found her father’s telephone number in her bag,then I phoned her father .The doctor told me that the girl has been away from dangerous,then I left for the cinema.
When I arrived the cinema ,the film had been over already.
But there was no regret in my heart.
