I know how it works 我知道規矩
這里的work不是指“工作”,而是指“事物運作的道理與規范”,類似于行規的概念:
A:I am afraid we are going to have to fire you. 我恐怕我們得開除你。
B:It's OK. I know how it works. You just don't like me.
沒關系,我知道行規。你就是看不慣我。
Work 也有“運作”的意思:
A:Can you work a couple of basketball tickets for us?
你能幫我們弄幾張籃球票來嗎?
B:I'll see what I can do. 我來想想辦法。
