原文：团结就是力量。这力量是铁，这力量是钢，比铁还硬，比钢还强。

分析原文：原文本身就有问题，既然这力量是铁，为何比铁还硬，这不相当于自相矛盾了？是铁就是铁，为何比铁还硬，既然比铁还硬，那你还是不是铁？

翻译分析：

初译

Unity is more powerful than iron and steel.

2. 再译

因为大家都知道铁没有钢硬，所以这句的目的是为了体现团结力量很大，举了铁和钢的例子，但是只要比钢强，必然比铁还硬，所以比铁的例子可以省略掉，是废话，译文改为Unity is more powerful than steel. 

1）原文中如果有自相矛盾的，要修改正确，比如歌词里 是铁，比铁还硬，就要修正。

2） 原文中如果有冗余要删掉，既然比刚还强，必然比铁还硬，删掉铁。

3） 用谷歌查证是否有more powerful than steel这种表达法，以确保英文表达地道。

3. 三译

这里还有一句 Honor is a force more powerful than steel 

套用就是 Unity is a force more powerful than steel. 

4. 四译
