阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

    When I was 12, all I wanted was a signet (图章) ring. They were the "in" thing and it seemed every girl except me had one. On my 13th birthday, my Mum gave me a signet ring with my initials(姓名首字母) carved into it. I was in heaven.

What made it even more special was that it was about the only thing that wasn't being "re placed". We'd been burnt out in fires that swept through our area earlier that year and had lost everything—so most of the " new" stuff (东西) we got was really just to replace what we'd lost. But not my ring. My ring was new.

    Then, only one month later, I lost it. I took it off before bed and it was missing in the morning. I was sad and searched everywhere for it. But it seemed to have disappeared. Eventually, I gave up and stopped looking for it. And two years later, we sold the house and moved away.

    Years passed, and a couple of moves later, I was visiting my parents' when Mum told me that she had something for me. It wasn't my birthday, nor was it Easter or Christmas or any other gift-giving occasion. Mum noticed my questioning look. "You'll recognize this one," she said, smiling.

Then she handed me a small ring box. I took it from her and opened it to find my beautiful signet ring inside. The family who had bought our house 13 years earlier had recently decided to do some redecorations, which included replacing the carpets. When they pulled the carpet up in my old bedroom, they found the ring. As it had my initials carved into it, they realized who owned the ring. They'd had it professionally cleaned up by a jeweler before sending it to my mother. And it still fits me.

汉字危机

王小峰

中国的书写交流进入键盘划时代只有十几年,任何一个初次接触电脑的人通过简单的学习都能迅速掌握文字输入。随着电脑的普及,现在很多人写字总是提笔忘字,尤其是经常使用的汉字往往一下想不起来了,这跟他受过高等教育掌握无数信息和知识的身份有点不符。很多人纷纷惊呼汉字危机来了,拯救汉字刻不容缓。

书写是记忆汉字的最好方式,只有经常书写,才能记住一个字该怎么写。过去用笔书写汉字基本上是音、形、义同时进行,键盘输入就出现问题了,它不是直接写汉字,而是让你在候选的重码中去选择正确的那个字。这就是汉字在键盘输入时代面临的一个问题,换句话说,这就是音素文字和语素文字的最大区别。所有音素文字(英语、德语、法语、西班牙语等)它们只有音和形,而且音形基本统一,打字本身就是书写过程。我们是拼音解决汉字输入问题,而不是在键盘上打笔画。五笔字型不会让你忘记一个汉字怎么写,但是可能会让你忽略它该怎么读;拼音输入可以让你知道一个字怎么读,却让你慢慢忘记它怎么写。在信息时代,中国人开始遇到能说能读能输入但可能不会写的问题了。这也暴露了汉字的自身局限问题。

网络时代屡屡出现新词,人们对“雷”、“囧”这类汉字就赋予新的含义。从每年出现的网络流行语中不难看出,新的词语越来越多,看上去也越来越没文化含量,继而还可能导致汉语的使用环境和美感越来越差。网络语言通过互联网的病毒式传播迅速扩散全球,但死得也非常快。它只是迎合某一类信息某一种情绪在传播的当口被创造出来,并随着这种氛围的消失而慢慢消亡,能留下来的凤毛麟角。

为了提高书写效率,方便学习和交流,开始出现俗字、新字,汉字的数量在不断增加,但却有不断简化的趋势。是否要恢复繁体字的讨论没有太大意义,因为很多汉字究竟怎么写,它的结构组合究竟是什么意思你可能都觉得不重要了。今天80%以上的中国人都会使用汉字、这其中多数人就像街头对话一样也仅仅是用来交流,而不是用来写作或研究。比如你打一个“爨”( cuan),用简拼敲四下就出来了,你不用去写31画,它比你打一个“装”(zhuang)还少两下,笔画已经不是键盘输入时代最让人疼痛的问题了。那么,汉字是否还要继续简化就不是问题了。

汉字在任何时代都有极强的适应性,不管是刻在龟甲上,还是刻在竹简上,还是写在帛上,或者写在纸上,乃至今天用计算机编码通过显示器显示出来,汉字从来没有因为它的复杂性而被淘汰或异化。而眼前,我们汉字要面临的最大问题是它如何适应全球化进程中的语言交流和传播。汉字在外国人看来是最难学的文字,汉语是最难掌握的语言。
