Although it's impossible to keep your hands germ-free, washing your hands is good for you. It limits the chance of getting sick and is one of the best ways to avoid(避免) getting sick and spreading illness. Staying healthy can make you feel happier.

方块汉字前途之争

    方块汉字的前途,是我国知识界争论的百年话题。

    对于汉字的批评,首先来自其复杂难学,历史上只为少数人所掌握。“五四”运动后推行白话文、拟定注音字母,进一步的主张就是废除方块字、实行拼音化。然而建国后的实践表明:通过汉字简化和义务教育,汉字完全可以为大众所掌握,本身并不是造成文盲的主要原因。

    时至今日,废除方块字的主张不再活跃,流行的一种观点是方块字不适合于科学表达,不如拼音文字那样逻辑分明,因此汉字可以用来传承文化而不适用于发展科学。其实这里混淆了科学发展的传统背景和语言载体本身的特色。国人撰写的学术论文,无论用的是中文还是英文,往往有着论证不严、逻辑不清的毛病,这里既有我国传统文化中不利于科学发展的遗传病,也有在近代封闭条件下形成的恶习惯。文字无辜,这些毛病不该记在文字头上。

    计算机技术的发展,为各种文字的前途提供了重新排队的机会。对于二进制的计算机编码而言,一个汉字只相当于两个拼音字母。同一个文本,汉字的篇幅最短,输入计算机的速度也最快。汉字直观,承载的信息量远大于拼音文字。更重要的是汉字信息熵【shāng】最高,有限数量的方块字经过搭配,可以构成无限多的新词;而依靠拼音字母的英文,需要不断制造新的单词才能表达不断出现的新概念。因此,汉字常用的只有几千字,而英语的词汇量早已超过40万,在应对新概念大量涌现的科学发展中并无优势。

    语言是文化传承的主角,以汉语作为载体的中华文化,在科学创新中应当具有潜在的优势。一种文化能够保持几千年而不衰,其中必有原因。值得参考的是犹太民族,三千年历史有两千年流离失散,却始终坚守着犹太教和希伯来文。在外界压力下,犹太人凭着对知识和智慧的重视,以一千多万的人口,赢得了世界四分之一的诺贝尔奖。华夏文化同样具有尊重知识和智慧的传统,是不是也在深处蕴藏着科学创新的基因,从而也有问鼎世界科学顶峰的前景?
