蜗牛在科学课堂上，老师要我们观察蜗牛。
于是我回家后就到花园里去寻找。
可是，我怎么也找不到这种小东西。
较后，在爷爷的帮助下，终于在一个潮湿的墙角里找到了两只小蜗牛。
In the science class, the teacher asked us to observe snails.
So when I got home, I went to the garden to look for it.
However, I can't find such a small thing.
Finally, with the help of my grandfather, I found two little snails in a damp corner.
本来在课堂上听了老师讲蜗牛，我就感到很新奇。
遥看到了真的蜗牛，我要把它仔细地观察一番。
I had heard the teacher talk about snails in class, and I felt very novel.
Now that I see the real snail, I want to observe it carefully.
它们的背上背着一个漂亮遥的“小房子”，柔软的身体就藏在这个房子里。
我把它们放在一个小盒子里开始观察。
They carry a beautiful and delicate "little house" on their back, and the soft body is hidden in this house.
I put them in a small box and began to observe.
我发现蜗牛好像没有骨头，身体柔软，全身湿漉漉的。
头部有一对螺旋形的触角，对外界遥有敏感的反应。
如果把它放在阳光下暴晒，它们很快就从用薄膜封闭着的“门洞”里出来了，这说明蜗牛非常害怕强光的直射。
蜗牛爬过的地方会留下一道白遥的痕迹，在阳光下闪烁。
这说明它行走时需要润滑。
I found that snail seems to have no bones, soft body and wet body.
The head has a pair of spiral antennae, which are sensitive to external stimuli.
If it is exposed to the sun, they will soon come out of the "door hole" sealed with a film, which shows that the snail is very afraid of direct sunlight.
The place where the snail climbs will leave a white trace, twinkling in the sun.
This means that it needs lubrication when it walks.
可是，蜗牛的嘴在哪儿呢？
我找来一个放大镜仔细地看才发现一个很小的圆点，我想蜗牛一定吃得很慢。
于是我做了一个实验。
我拿来一片菜叶放在盒子里，把蜗牛捉来让它吃。
我等了好遥间也没有看到它吃菜叶，我就把盒子盖严，去睡午觉了。
当我醒来的时候，我吃惊地发现蜗牛把叶子快吃完了。
But where is the snail's mouth?
I found a magnifying glass to look carefully and found a very small dot.
I think snails must eat very slowly.
So I did an experiment.
I brought a vegetable leaf and put it in the box.
I caught the snail and let it eat.
I waited for a long time and didn't see it eating vegetable leaves, so I closed the box tightly and took a nap.
When I woke up, I was surprised to find that the snail was eating up the leaves.
但我始终没有看见它吃东西 ，我想它可能是在黑暗中吃吧。
我再仔细一看，盒子里有许多黑遥的小颗粒，放菜叶时并没有这些东西，那一定就是蜗牛的排泄物了。
我大概睡了三个小时，这说明蜗牛是在黑暗中吃东西，而且吃得很慢。
蜗牛真是一种神奇的小动物，特别是他那背在背上的保护着它的“小房子”，给人留下遥其美好的感觉。
Snail is really a kind of magical small animal, especially the "little house" which protects it on its back, leaving a very good feeling to people.
