如“虽然…但是…，尽管…”等。

Although humans are the most intelligent creature on earth，anything humans can do, Nature has already done better and in far, far less space.

分析：although引导的让步状语从句译成虽然…但…。

参考译文：虽然人类是地球上最聪明的生物，人能创造一切，但大自然更富于创造性，早已创造出比人类创造的更好更小巧的东西。

二、译成条件句

由no matter引导的从句可以译为以不论，不管，无论等做关联词的条件分句。例如：

No matter how carefully you move your hand toward a fly, the insect will dart off almost every time.

参考译文：不管你多么小心翼翼地把手伸向一只苍蝇，差不多每次它都飞走。
