Last on Friday in the morning, I and classmate discovered a few small snail in the corner of wall together. Fear all along because of me the insect, be afraid of even a small ant half-deadly, so I am frightened run to go at the same time.

上个星期五的上午,我和同学一起在墙壁的角落里发现了几只小蜗牛。因为我一向害怕昆虫,就连一只小蚂蚁都怕得半死不活的,所以我就吓到跑到一边去了。

I always feel snail very do not tell sanitation, the place of 4 that long antenna is particularly ugly, advocate what if climb the place that pass to still can stay,be fed up with is mucous, still perhaps can climb my body to go up! Want to feel to fear.

我总是觉得蜗牛很不讲卫生,那长着四只触角的地方特别难看,主要是爬过的地方还会留下讨厌的粘液,说不定还会爬到我的身上呢!想想都觉得害怕。

At this moment, classmate Wu Zhuofan called me: “ Zhou Xinyu, snail does not bite a person again, what are you afraid of? I roused ” eventually courage, come to snail beside looked carefully. Well? Snail seems to also be held out lovely ah! Cabinet and delicate crust, seem to be touched with respect to meeting go to sticks and staves; The body that soft toot toots, the mucus that leave also was fed up with it seems that, in hair full marks sparkles below sunshine / smooth. I generated huge interest to snail, with respect to pick up a small club, touch touch snail is hard and flimsy case, snail shrinks immediately went back. Passed for ages, showed 4 small antenna first, turn, the little face of Yi shows back-to-back that Zhang Ka, show the body entirely finally, crawling slowly ahead again next ……

这时,同学吴卓凡叫住了我:“周新愉,蜗牛又不咬人,你怕什么?”我终于鼓起了勇气,来到蜗牛身旁仔细地看了起来。咦?蜗牛好像也挺可爱的呀!小巧而精致的外壳,好像一碰就会碎掉;软嘟嘟的身体,留下的黏液似乎也不讨厌了,在阳光底下闪闪发满分/光。我对蜗牛产生了极大的兴趣,就捡起一根小木棍,碰碰蜗牛坚硬而脆弱的壳,蜗牛马上缩回去了。过了好久,先露出来了四只小小的触角,转了转,紧接着把那张卡哇伊的小脸露出来,最后把身子全部露出来,然后又向前慢慢地爬行着……

Classes are over come home, I searched the data of snail on the net. Original: Of snail mucous because the skin has the pleopod of snail to be able to secrete mucous sufficient gland in great quantities commonly,be, when snail is crawling, group can leave on the ground mucous. What mucus can maintain abdominal foot or leg already is wet, can reduce the ground to wear away to cutaneous again. The desiccate after bequeath is contacted with air in ground mucus, make the line of the glow of a silvery white.

放学回家,我在网上查找了蜗牛的资料。原来:蜗牛的粘液是因为蜗牛的腹足皮肤一般都有大量能分泌粘液的足腺,蜗牛在爬行时,会在地上留下一行粘液。黏液既能保持腹足的湿润,又能减少地面对皮肤的磨损。遗留在地面上的黏液与空气接触后变干,成为一条银白色的发光的线条。

Original, snail also is a kind of lovely gnat!

原来,蜗牛也是一种可爱的小昆虫呀!(文/周新愉)
