+# 1.1 字母（Alphabet）
+
+英语总计使用 26 个**字母**（*letters*），各有大小写之分。在欧洲语言之中，英语是罕见的不使用**修饰符**（*diacritics*）的文字 —— 所谓修饰符，指的是字母上附加的标记，用以区分发音或者意义，比如，*â*、*é*、*ç*，等等。
+
+Modern English is composed of *26* letters, each with both *uppercase* and *lowercase* forms. English stands out among European languages for not using [diacritics](https://en.wikipedia.org/wiki/Diacritic), which are special marks added to letters to alter their pronunciation or meaning, such as *â*, *é* or *ç*, etc.

+北约（NATO）有一套指称英文字母的系统，用以在仅有语音交流的情况下避免歧义 —— 在军事、航空、紧急救助、无线电或者电话沟通等诸多场合中具备不可或缺作用。
+
+[NATO](https://en.wikipedia.org/wiki/NATO) has a system that uses common words to identify each letter, which is particularly helpful for military and civil aviation, emergency serivces, radio or phone communication, and many others to avoid confusion when spelling out words.
