ECHO 世 界 语 简 介 Kio Estas Esperanto
ECHO 世界语(Esperanto)是波兰的柴门霍夫博士于1887年公布的一种国际辅助语方案。
ECHO 随着社会的发展， 各国政治、经济、文化及科学技术交流合作日益增多，这就迫
ECHO 切需要一种国际共同语， 以解决世界民族语言的繁杂性所造成的交流障碍。但现在任
ECHO 何一种民族语言都无法担此重任。 这是因为一方面，选用任何一种民族语言都会对其
ECHO 它民族造成感情上的伤害与事实上的不平等；另一方面，任何一种民族语都是在长期复
ECHO 杂的历史条件下形成的，不可避免的包含很多不规则，不合理的成分，给其它民族的学
ECHO 习者带来极大困难。 所以，这种国际共同语必须是中立，不属于任何民族，并且简单
ECHO 易学，而且富有表现力的。 而世界语正是这样一种语言。
ECHO 世界语书写形式采用拉丁字母，同一个字母在任何单词中的发音都是相同的。只要
ECHO 学会了28个字母， 掌握了拼音规则，即可读出和写出任何单词。 世界语的词汇源于自
ECHO 然语言 （主要是印欧语系所属语言）中的国际化成分。 它还通过附加前缀，后缀及词
ECHO 根间的组合来构成新词。 这不但增强了它的构词能力，而且大大减少了基本词汇量，
ECHO 减轻了人们记忆单词的负担。世界语的语法规则是在印欧语系的基础上制定的，简单明
ECHO 了而又不失严谨。 其基本文规只有16条。由于世界语的上述特点，使得它比任何一种
ECHO 外语都容易学习。 在世界语的单词中，每一个字母的音值始终不变，句子中也没有连
ECHO 读现象， 因而口语及听力很容易掌握。熟悉了语法规则， 掌握2000个左右的词根及词
ECHO 缀，即可自由地通信，交谈，毫无困难地进行交流。

ECHO Esperanto Introduction Kio Estas Esperanto
ECHO Esperanto is an international auxiliary language scheme announced by Dr. L. L. Zamenhof of Poland in 1887.
ECHO With the development of society, the exchange and cooperation of politics, economy, culture and science and technology among countries are increasing day by day, which urgently needs an international common language to solve the communication obstacles caused by the complexity of the world national languages. But any existing national language cannot take on this task at present. This is because on the one hand, any national language selected will cause emotional harm and de facto inequality to other nationalities; on the other hand, any national language is formed under long-term complex historical conditions, and inevitably contains many irregular and unreasonable components, bringing great difficulties to learners of other nationalities. Therefore, this international common language must be neutral, not belonging to any nationality, and simple and easy to learn, and rich in expressiveness. And Esperanto is such a language.
ECHO The writing form of Esperanto adopts the Latin alphabet, and the pronunciation of the same letter in any word is the same. As long as you learn 28 letters and master the spelling rules, you can read and write any word. The vocabulary of Esperanto comes from the internationalized components in natural languages (mainly the languages belonging to the Indo-European language family). It also constitutes new words by adding prefixes, suffixes and combinations between roots. This not only enhances its word-forming ability, but also greatly reduces the basic vocabulary amount and lightens people's burden of remembering words. The grammar rules of Esperanto are formulated on the basis of the Indo-European language family, simple and clear and still rigorous. Its basic grammar rules only have 16 items. Due to the above characteristics of Esperanto, it is easier to learn than any foreign language. In the words of Esperanto, the phonetic value of each letter is always unchanged, and there is no liaison phenomenon in the sentence, thus the spoken language and listening are easy to master. Familiar with the grammar rules, master about 2000 roots and suffixes, you can communicate and talk freely, and carry on the communication without difficulty.
