所谓让步状语从句就是退一步说，举几个例子。The villagers have told him that they will not accept the pub even if he gives it away.

村民们告诉他，就算他把酒店才送人，他们也不会要。

也就是说，退一步说，你送都不要，卖就更没人要了。

再如，

Experts confirmed that the puma will not attack a human being unless it is cornered.

专家确认美洲狮不会攻击人类，除非被逼的走投无路。

换言之，退一步说，你要是逼它，它可就不客气了。

Although Pythagoras himself is very early, the influence of his school is mainly subsequent to that of other phylosiohors.

尽管毕达哥拉斯更早一些，但他的学派的影响却后于其他哲学家。

退一步说，他如果生在其他哲学家之后，他的学派的影响不就更滞后于其他哲学家了吗。

从这个意义上可推演出，无论从句的叙述的情况如何，主句所描述的事情都会照常进行。

Although mankind has undergone no general improvement in intelligence or morality, it has made extraordinary progress in the accumulation of knowledge.

尽管人类在智利和道德上没有什么进展，但在知识积累方面却取得了很大进步。

换句话说，无论智利和道德如何，知识是积累了不少。
