我服你了！

You beat me. 绝对地道的口语,如果照直翻译的话都不地道的。

You convinced from head to toe.

You win.

I almost feel compelled to admire you(我几乎不得不佩服你了.讽刺用语).例如I almost feel compelled to admire you. You always think twice before you say absolutely nothing!我几乎不得不佩服你了，你在什么也没说以前总是考虑再三。<BR>注：讽刺有些人谨小慎微，思前想后，什么也不敢说。

我服了你了
I'm totally shocked by you .
I'm taken aback by you .

你说得有道理，我服了。
What you've said is reasonable. I'm convinced

You got me!
