The module containing the policy routines is architecture independent and the part containing the mechanisms is architecture specific. The policy routines invoke the mechanisms as and when necessary. Such an OS can be ported to a new computer system by rewriting the mechanisms module for the new system, and integrating it with the policy module.

包含策略例程的模块是与结构无关的，而包含机制的模块是与结构相关的，策略例程只在必要的情况下才使用机制。这样的操作系统只重写机制模块就可以与策略模块结合，移植到新的系统上。

In January food fell short. The corn ration was drastically reduced, and it was announced that an extra potato ration would be issued to make up for it. Then it was discovered that the greater part of the potato crop had been frosted in the clamps, which had not been covered thickly enough. The potatoes had become soft and discoloured, and only a few were edible. For days at a time the
animals had nothing to eat but chaff and mangels. Starvation seemed to stare them in the face.
It was vitally necessary to conceal this fact from the outside world. Emboldened by the collapse of the windmill, the human beings were inventing fresh lies about Animal Farm. Once again it was being put about that all the animals were dying of famine and disease, and that they were continually fighting among themselves and had resorted to cannibalism and infanticide. Napoleon was well aware of the bad results that might follow if the real facts of the food situation were known, and he decided to make use of Mr. Whymper to spread a contrary impression.

  　一月份，食物就开始短缺了。谷类饲料急骤减少，有通知说要发给额外的土豆来弥补。可随后却发现由于地窖上面盖得不够厚，绝大部分土豆都已受冻而发软变坏了，只有很少一些还可以吃。这段时间里，动物们已有好些天除了吃谷糠和萝卜外，再也没有别的可吃的了，他们差不多面临着饥荒。  

  　对外遮掩这一实情是非常必要的。风车的倒塌已经给人壮了胆，他们因而就捏造出有关动物庄园的新奇的谎言。这一次，外面又谣传说他们这里所有的动物都在饥荒和瘟疫中垂死挣扎，而且说他们内部不断自相残杀，已经到了以同类相食和吞食幼崽度日的地步。拿破仑清醒地意识倒饲料短缺的真相被外界知道后的严重后果，因而决意利用温普尔先生散布一些相反的言论。
