For example, eggs can easily turn into omelettes but not the other way around, and milk and coffee mix in your cup but never separate out again.

例如，鸡蛋很容易变成鸡蛋饼，但是却不能变回鸡蛋。咖啡和牛奶在杯子中混合，但是却不能再一次把他们分开。

Breakfasts in the dining car are hearty: freshly baked muffins, oatmeal and omelettes, bacon and eggs (I'm smitten by the blueberry-bursting pancakes).

我们在餐车了美美地享用了早餐：新鲜烤制的松饼，麦片，火腿和鸡蛋。我被蓝莓馅饼塞得饱饱的。

You can't have omelettes without breaking eggs, and I have no doubt that the omelette which eventually emerged justified the breaking of a good many eggs.

你不能不打破鸡蛋而有炒鸡蛋。我敢肯定最后端出来的炒鸡蛋足以证明把许多鸡蛋打破是有道理的。
