I had raised silkworm darling, from inside its exuvial process, harvested a lot of knowledge and grow.

我养过蚕宝宝,从它的蜕皮过程中,收获了许多的知识和成长。

That day, I am same as usual return the home, open the box of sericiculture darling. "Oh, sangxiegan, change immediately. " I run to the balcony rapidly, the Sang Xie with new fetch, the composition Zhang Zhang of mulberry Xie Yi is put in the box. Silkworm darling smelled it seems that Sang Xie's scent, the body with rounded move climbed twist in succession, round Sang Xie, "Rustle is sanded " the ground is gnawed.

那天,我和往常一样回到家,打开养蚕宝宝的盒子。“噢,桑叶干了,得马上换掉。”我赶紧跑到阳台,取来新的桑叶,把桑叶一张张放到盒子里。蚕宝宝似乎闻到了桑叶的芳香,扭动着滚圆的身子纷纷爬了过来,围着桑叶,“沙沙沙”地啃开了。

Abrupt, I discover among them the silkworm darling of an extraordinary: Appear on its body flaxen, there also is a transparent triangle on the head. Did it fall ill? I put it inside another box to observe carefully alone. Not a little while, saw a crack appears slowly on the head of that silkworm only, back-to-back move is seamed that coarsen gradually greaten, bag of a cerebella was gotten out from which slowly. That cerebella bag does not have what effort it seems that, hanging down downward continuously. So it is in cost off a skin! The head that sees it then is controlled again and again sway, keep forth explore, can be cuticular very not obedient, always be firmly ground adheres its body.

突然,我发现其中一只与众不同的蚕宝宝:它身上呈现淡黄色,头上也有一个透明的三角形。它是不是生病了?我把它单独放在另一个盒子里面仔细观察。不一会儿,只见那条蚕的头上慢慢地出现了一道裂痕,紧接着那道缝渐渐地变粗变大,一个小脑袋慢慢地从中钻了出来。那个小脑袋似乎没有什么力气,直往下垂着。原来它是在蜕皮!接着看见它的头频频地左右摇摆,不停地往前探,可是表皮很不听话,总是牢牢地粘住它的身子。

Why is silkworm met exuvial? My determination lane knows it. The solution found very quickly in the book: The silkworm that original hatch comes to eats Sang Xie be brought up slowly, when the body is restricted cuticularly, silkworm is about exuvial. General every other 3 days two with respect to exuviate skin, its brief lifetime wants exuviate 6 times in all skin.

蚕为什么会蜕皮?我决心弄懂它。很快在书中找到了答案:原来孵出来的蚕吃桑叶慢慢长大,当身子受到表皮的限制时,蚕就要蜕皮了。一般每隔两三天就蜕一次皮,它短暂的一生共要蜕六次皮。

At this moment silkworm darling has been gotten out completely from skin, obtain newborn silkworm darling whiter than before, more fat also. For can spin knot chrysalis, silkworm darling not the anguish of Wei cost off a skin, really respected but admire! If people also can resemble silkworm baby same, encounter difficult unremitting to try hard to overcome, also can obtain more brilliant positive result certainly.

这时蚕宝宝已经从表皮里完全钻出来了,获得新生的蚕宝宝比以前更白了,也更加胖了。为了能够吐丝结茧,蚕宝宝不畏蜕皮之痛苦,真是可敬可佩!人们如果也能像蚕宝宝一样,遇到困难坚持不懈努力克服,也一定能取得更加辉煌的成果。
