Translation of "Chasing" in Chinese

I see a cat chasing a dog.

我看见一只猫追着一只狗跑。

You're beautiful and intelligent, how is it possible that no man is chasing after you?

你这么漂亮，况且又这么聪明，怎么可能没人追你呢？

I applied my heart to know wisdom, and to know madness and folly. I perceived that this also was a chasing after wind. For in much wisdom is much grief; and he who increases knowledge increases sorrow.

我一心追求智識，也了解了瘋狂與愚蠢。我覺得這就像是追著風跑。智識的背後是傷悲，所以追求智識之人也多了幾分悲傷。
