时差N小时 冰箱可抑制食物滋生细菌(上)（在线收听）

Back when most folks relied on an icebox to cool food, a block of ice was a precious commodity.

以前大多数人们靠冰盒冷却食物，冰块是一件稀有商品。

If you put hot food in the icebox, the ice might melt.

如果你把热的食物放入冰盒，冰块会融化。

And by the time the ice truck came through the neighborhood again, all your food may have spoiled.

等运送冰块的卡车再次到来时，需要冷藏的食物兴许都已腐坏、变质。

To preserve the ice as long as possible, people made sure to cool hot foods before putting them in the icebox.

为了让冰块保存时间更久，人们会等食物冷却后再放入冰盒。

These days, before putting hot food in the fridge, many people cool it on the kitchen counter, just as generations before did in the icebox days.

现在，许多人会把热的食物放在厨房桌面上，待其冷却后再放入冰箱前，跟老辈人的做法一致。

But now there’s no precious block of ice to preserve, and refrigerators are designed to handle food hot off the stove or out of the oven.

如今，我们不再利用稀有的冰块冷藏食物，冰箱可以储藏刚从烤炉或烤箱烤熟的食物。
