Some simple Esperanto rules
一些简单的世界语规则
Each letter has a unique and separate sound. For example: longa is pronounced "lon-ga". Both k and n are pronounced in knabo.
每一个字母都有它唯一且独立的发音，例如：longa的发音是“long-a”。k和n在knabo里面都要发音。
The emphasis in every word is always on the next-to-last syllable. For example: all 2-syllable words have the emphasis on the first syllable, as in viro, and all 3-syllable words have the emphasis on the middle syllable, as in knabino.
每个单词的重音都在倒数第二个音节。例如：所有的双音节单词的重音都在第一个音节，例如viro,所有的三音节单词的重音在中间的音节，例如knabino
All action words (verbs) always end in -as, when talking about what is happening now. Examples: mi laboras (I work/I am working); mi estas (I am); vi dormas (you sleep/you are sleeping).
所有表示动作的单词（动词）通常以-as结尾，谈论的是正在发生的事情。例如：mi laboras (我在工作); mi estas (我是。。。。); vi dormas (你在睡觉).
All words for a thing (or a person, an animal, a place, etc), end in -o. For example: libro (a book), viro (a man), hundo (a dog), Aŭstralio (Australia).
所有表示物体（人、动物、地点等）的词以-o结尾，例如 libro (书本), viro (男人), hundo (爱宕), Aŭstralio (澳大利亚).
"The" is la in Esperanto. For example: la viro = the man.
英语里的“The”是世界语里的la，例如：la viro = the man.（那个男人）
"A" and "an" are not used in Esperanto. For example: viro = a man.
在世界语中并不使用“A”和“an”（即不定冠词），例如viro = a man.
-in means female: viro = man, virino = woman; knabo= boy, knabino = girl; aktoro = actor, aktorino = actress.
-in的意思是雌性：viro = man（男人）, virino = woman（女人）; knabo= boy（男孩）, knabino = girl（女孩）; aktoro = actor（男优）, aktorino = actress（女优）.←别想歪

Esperanto keyboard
世界语键盘
To obtain an Esperanto keyboard that will allow you to easily type these special characters, please refer to our forum by following the link below:
安装一个世界语输入法能够让你更容易地打出这些重音字母,请参考我们的论坛：forum.duolingo.com/comment/8841170

What if I don't want to install a keyboard just for this course?
如果我不想就为了上这堂课而安装输入法呢？
Duolingo recognizes the x-system, an alternative method of entering the accented Esperanto characters. To use the x-system, simply type the letter that requires the accent followed by an x:
多邻国能够辨识X写法，这是一种常见的世界语重音字母输入法。使用X写法输入字母。用X代替字母所需要的重音符号即可

Example: type sxangxo to spell ŝanĝo
例如：输入sxangxo来表示ŝanĝo（改变）
Note that Duolingo will not convert accented characters entered via the x-system in the answer immediately when typed, but will recognize them when they are submitted for checking.
注意一下:多邻国不会马上将你用X写法输入的重音字母自动切换为正常的重音字母。不过它会在上传的答案中识别出来的。
