介紹： 指甲總是剪了又長，剪了又長，而且長出來不想頭發(fā)一樣軟軟的，指甲是硬硬的，而且我們需要經(jīng)常剪指甲，小朋友們知道為什么嗎？指甲每天都在生長，長時(shí)間不剪，越長越長。人的雙手每天都會(huì)碰到許多東西，因此，受傷會(huì)沾滿許多細(xì)菌和寄生蟲卵。這些細(xì)菌就在指甲縫里。當(dāng)我們用手來吃東西的時(shí)候，這些細(xì)菌就會(huì)和食物一起被吃進(jìn)肚子里了，人就會(huì)生病。指甲有兩個(gè)用處，一是保護(hù)手指；二是有利于干活，因?yàn)槿说氖种改軌蜢`活的寫字、拿東西，都要靠指甲的支撐。但是如果指甲太長，細(xì)菌和污垢便容易藏在指甲縫中。指甲縫中的污垢較難清潔，也不美觀。而且，如果指甲太長也容易在無意識(shí)的時(shí)候，刮傷自己的臉或者碰到硬物導(dǎo)致指甲斷裂。指甲這么臟而且長指甲又這么的危險(xiǎn)，所以小朋友們要經(jīng)常修剪指甲，保持清潔衛(wèi)生。
