我确实在这里付出了代价。

I do pay a price here.

也正因为如此我和我的家庭为此付出了我知道终有一天必须付出的代价。

For this I - and my family - have paid the price that I had long known I would one day have to pay.

I have constant time access which is great, but I paid a price, which is I had to use up some space.

我的访问时间现在是常数级别，这个非常的棒，但是我也付出了代价，不得不使用更多的空间，在整数的例子中。
