What Lives in a Shell

What Lives in a Shell?

谁住在壳里

Do you know what this is? It is as hard as a stone. But it is not a stone. It is smooth, like glass. But it is not glass. It is hollow inside, like a cup. But it is not a cup. It is a shell. An animal made it. The shell wasthe animal's home.

你知道这是什么吗?它硬得像石头，又不是石头。 它的里面空空的，像杯子，又不是杯子。它是壳，一种动物的组成部分。壳就是一些动物的家。

You live in a house or in an apartment building. That is your home. Your home keeps you safe and warm. Lots of animals have homes. Birds build nests. Ants make tunnels underground. A bear likes to live in a cave.

你住在一栋房子或公寓大楼里，那是你的家。家让你感到安全又温暖。 许多动物都有家。鸟儿筑窝巢。蚂蚁在地下挖隧道。大熊喜欢住在山洞里。

Here is the animal that lives in this kind ofshell. It is a land snail. A land snail is born with a tiny shell. Aslong as the snail lives, it keeps on growing. As the snail grows, its shell grows with it. The shell keeps the snail safe.

这儿就有一种动物住在壳里。它叫蜗牛。 蜗牛生下来就带着小小的壳。只要它活着，壳就会一直长。 蜗牛长大了，壳也跟着一起长大。壳能保护蜗牛的安全。

You can go in and out of your home. You can runto the playground. You can wait outside for the bus. A snail never leaves its home. It takes its homewith it wherever it goes.

你可以进出自己的家，可以跑去操场玩，可以在外面等车。 蜗牛从来不离开自己的家，不管去哪儿都带着它

The snail pokes its soft head and its one big foot out of the opening in its shell. It uses its foot to inch along. A snail is slow. Birds like to eat snails. When a bird or otherenemy comes around, a snail cannot run away. It pulls its head and foot inside its shell andcloses the door. The snail is safe.

蜗牛把柔软的头和一只大脚从壳口伸出来。大脚一点一点地移动，很慢很慢。 鸟儿喜欢吃蜗牛。附近有鸟儿或者其他敌人的时候，蜗牛没办法很快逃走。它把头和大脚缩进壳里，再关上门，就安全了。
