历史 经济 难度 对人类文明的贡献 2. http://bbs.hupu.com/12561712.html
短期看不太可能。决定语言传播的有几个因素：
1. 国家实力（说中文的就中国一个大头）
2. 文化输出（这点上天朝弱爆，天朝目前以及可短期预见的未来里，不具备输入文化的足够实力）等哪天天朝的流行文化，各种文化，电影，流行歌，书，明星等逆向输入英语世界，等哪天英语国家的青少年开始哈中了，这时候我们才谈中文的逆袭。
3. 本身语言文字的难易度。中文不是一个利于快速传播的语言，后天习得难度巨大。 3. Document1 (paragraph4) 4.

The definition of global language
A global language is a language spoken internationally and that is learned by many people as a second language. A world language is characterized not only by the total number of speakers (native and second language speakers), but also by its geographical distribution, and use in international organizations and diplomatic relations. 1. A language cannot be determined as a global language by using the evidence of how large the numbers of people speak it as a mother tongue
