If I don't like this job, I won't put my time and heart to finish it. 这是很口语的说法,用put my heart 来说。书面的话,可以这样说:If I don't like this job, I won't spend time and energy finishing it.
"经营"这个词用得不是很好吧!"经营"一般带有盈利性的,应该用"管理"才差不多.管理这些组织、社团,我投入了大量的精力或热情,但是我也从中学得了许多。 I have devoted many my energies and enthusiasms to manage these organizations and Associations, and I have benefited lots of from it.
I have given all my effort and passion to contribute in these organizations and communities, in which I really learned a lot !经营感觉用的有些不妥,我把它改成“做出贡献”很地道的
