▲表示语言类名词，原则上都是不可数名词，通常没有复数形式，通常也不连用不定冠词。如：Spanish is her native language. 西班牙语是她的母语。You will be examined in French and German. 你将要接受法文和德文的考试。▲但若表示某种语言，有时也连用不定冠词。如：He speaks an English that I can barely understand at all. 他说的英语，我简直听不懂。▲表示不同种类的语言或某种语言的不同变体，则有时也用复数。如：World Englishes 世界上英语的各种变体——以上摘自“英语语法网”的《英语语言类名词用法说明》一文：http://www.yygrammar.com/Article/201203/2795.html ▲English用于复数的补充例句：1. Besides British English and American English, there are other Englishes such as Canadian English and Australian English. 除了英国英语和美国英语外，还有其他种类的英语，如拿大英语和澳大利亚英语。2. Doyou know that there is more than one kind of English? In some important waysthey are very different from one another. They are called world Englishes.（人教版英语教材必修1第9页）
