我最大的梦想是成为一名警察。翻译成英文

my largest dream is to become a policeman
my greatest dream is to become a policeman

但是注意不要用biggest，相信我吧，

My biggest dream is to become a policeman.

我最大的梦想是成为一名警察
I biggest dream becomes police

my greatest dream is to become a policeman
largest好像用在这里也不是很妥吧
它不是一般情况下都用在物体的体积方面的麼?你确定能这麼用的吗?

My greatest dream is being a policeman\policewoman.

呵呵，其实大家不应该直译的，会很别扭
直接可以翻成I want to be a policeman most.
