Where Do CHICKS Come From?

小鸡从哪里来

Tris is an egg, You've seen eggsbefore, but this one is different. Inthree weeks, a chick will hatch outof this egg.

这是鸡蛋，你以前肯定见过鸡蛋。 可这只鸡蛋与众不同。三个星期之后，一只小鸡将从这只鸡蛋中孵出来。

An egg begins as a tiny white spot inside the mother chicken, the hen. There may be many tiny eggs inside the hen at onetime. A yellow yolk grows around each egg. ALBUMEN FORMS AROUND FERTILIZED EGGS YOLK BEGINS TO GROW SHELL DEVELOPS UNFERTILIZED EGGS Then the father chicken, the rooster, mates with the hen. His sperm joins the growing egg. This is called fertilization. Soon, a clear jelly-like egg white, or albumen, grows aroundthe yolk. Finally, a hard shell forms. The egg is ready to be laid.

每一只鸡蛋都由一个小白点发育而成，有时候，母鸡的身体里面会同时有很多枚小小的未受精的卵。每一枚小小的卵周围都围绕着一个蛋黄。 然后，公鸡和母鸡交配，它的精子进入正在发育的卵，这个过程就叫做受精。 很快，像果冻一样透明的蛋白(也叫蛋清)，开始围绕蛋黄生长，最后，坚硬的蛋壳形成。这时，母鸡就等着下蛋了。

The hen lays the egg. Over the nextfew days, she lays several more eggs. The hen sits on top of the eggs tokeep them warm. As soon as the eggsare warm, the chicks start growing.

母鸡产下第一只鸡蛋后，在接下来的几天里，还会陆续产下更多的鸡蛋。 它坐在鸡蛋上给鸡蛋保暖。当鸡蛋变暖后，小鸡逐渐在里面发育成长。

Inside the warm egg is everything a chick needs to grow. The yellow yolk contains liquid food. The albumen contains water and a little more food. A thin white skin grows around the yolk and albumen and sticks to the inside of the shell. It holds the albumen together to cushion the growing chick. At one end of the egg is an air space. This is where the chick will take its first breath. The egg you eat for breakfast could never grow into achick because it was never fertilized. Otherwise, all partsinside the egg are the same.

温暖的鸡蛋里有小鸡成长所需要的一切。 你早餐吃的鸡蛋，通常不会发育正成一只小鸡。因为它不是受精卵。 除此之外，鸡蛋里面的构造全都相同。

The hen has warmed her eggs forthree days now. Insidé, the chicksare growing.

这只母鸡坐窝孵蛋天了，小鸡正在蛋里慢慢发育。
