关于COCA
COCA, 全称 Corpus of Contemporary American English,它总结了英语国家使用频率最高的词汇,使用大数据的方法把 1990-2012 年美国最有代表性的报纸,杂志,小说,学术,口语(口语可能是用的电视剧或者脱口秀之类的节目转录的)汇集起来,每部分各占 1/5,生成 4.5 亿单词量语料库。
COCA词频表,是从众多语料库(corpus)中提取,用大数据的方法从各种文体中提取单词,并按照单词出现次数高低进行排序的一个词频表。
掌握前 500 单词,现实生活中能认识 70% 的单词;
掌握前 6000单词,现实生活中能认识 94% 的单词;
掌握前 9000单词,现实生活中能认识 97% 的单词;
掌握前 17631 单词,现实生活中能认识 99% 的单词。
按照这个词汇实用频率的顺序,从最高频率的开始学习,那对于英语的学习是非常高效的,我现在就在通过这个词频表进行复习和查漏.

本App 是COCA词频单词的简化版.
