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。我等了好长时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,盒子里有许多黑色的小颗粒,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。
