Here is a fairly long text from a science book aimed towards teaching children some easy scientific concepts and facts. The book attempts to explain various scientific questions and uses some excellent vocabulary and sentence structures to do so. Today, let’s look at why we shouldn’t be washing eggs as soon as we buy them.

As always, read as much as you an without resorting to any help. Most of the vocabulary is quite straightforward although there may be a few characters that are not very common.

Key Words

  • 科学 – meaning science. 不科学的 would mean unscientific
  • 仔细 – careful/attentive. For example 请仔细听 means please listen carefully
  • 容易 – easy/easily. This is used very often for example, 这东西吃多了容易倒胃口 meaning eating too much of this food will spoil your appetite.
  • 变坏 – To go bad. Eggs can go bad very quickly.
  • 孵 – hatch/incubate. This character looks complicated but is actually fairly unique-looking causing it to be easily identifiable.

Why does cleaning eggs cause them to degrade easier?

(Hover over the Chinese for pinyin)

为什么干净的鸡蛋更容易变坏

有时候刚刚买回来的鸡蛋,蛋壳往往看起来很脏,有的人会在凉水中冲洗鸡蛋,如果认为这样是卫生的,那就大错特错了。其实这种做法是不准确的,也是不科学的。

给你一面放大镜,仔细观察蛋壳就会发现蛋壳上有很多细微的小孔,你知道它们是做什么用的吗?告诉你吧,假如这是一个可以孵出小鸡的蛋,为了小生命可以存活,这些小孔是用来让小鸡呼吸的。这也表明,鸡蛋的内部和外界是通过小孔相同的。但是如果这只是一个普通的没有受过精的鸡蛋,它内部的水分就会通过蛋壳上无数的小孔蒸发掉;而外界的腐败菌等细菌也很容易通过这些气孔进入鸡蛋内部,使蛋变质,坏掉。但是一个没有被清洗过的鸡蛋,它的外壳上就会有一层粉末状的胶性物质,它的作用是封闭那些通气孔,使鸡蛋内外隔离开来,所以可以有效防止细菌侵入和水分的蒸发,有效地帮助鸡蛋保鲜。

这样看来,鸡蛋外壳上那些脏兮兮的东西对于保持鸡蛋的新鲜是有很大作用的。千万不要因为鸡蛋很脏就洗干净了存放,那样的话鸡蛋可能变质,变坏,这样的鸡蛋看着干净,可是吃下去就会影响身体健康。以后买鸡蛋的时候,要挑一些看起来被保护得更好的鸡蛋,用鸡蛋做菜的时候也最好现吃现洗。
