There are more than 2,700 languages in the world. In addition, there are more than 7,000 dialects. A dialect is a regional variety of a language that has a different pronunciation, vocabulary, or meaning. The language in which a government conducts business is the official language of that country. 1 billion people speak English. That's 20% of the world's population. 400 million people speak English as their first language. For the other 600 million it's either a second language or a foreign language. There are more than 500,000 words in the Oxford dictionary. 80% of all English vocabulary comes from other languages.
全世界除了有2700多種語言之外還有7000種方言。方言是指某個地區(qū)特有的，在發(fā)音、詞匯或含義上區(qū)別于其他語言的一種語言形式。 一國政府進行貿易活動時所使用的語言是這個國家的官方語言。 全世界講英語的人有10億，占世界總人口的百分之二十。其中4億人以英語為母語，另外6億人講英語作為第二語言或者外語使用。 在牛津字典中有50萬英文詞匯，其中百分之八十是外來詞匯。 （以上由melodyhan翻譯整理，歡迎與本人研究討論，共同進步。）
