关于英语学习 对于广大的英语学习者来说,不管你是学生,英语专业,还是普通的爱好者;英语单词都是英语学习之路上的一堵墙,难以逾越. 尤其对于非英语母语的人来说,学习英语是从单词学习开始的,单词的学习贯穿着整个英语的学习过程,由单词衍生出发音,读写,语句,形成整个英语体系;由此可见,英语单词的重要性. 你的词汇量,你精准掌握的单词数量,决定了你的英语学习的实际效果;较大的词汇量,能够在你的英语实践中(通常是看美剧,电影,视频等),让你快速融汇贯通;真正的刻在脑海中. 单词学习没有捷径,只有不断的积累;但是借助于好的工具,方法能够让你快速见效,形成体系. 曾经尝试过各类的背单词方式(托福,GRE,四六级等),效果一般;现在看来还是覆盖面不够广,过于局限. 一个偶然的机会接触到COCA(最知名的英语词汇词频统计库),顿时眼前一亮,这不就是我一直寻找的吗. 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. 关于词频单词APP 1.本App内置了17631个单词的词典,经过精细的筛选,去重,整理;按照COCA统计出的频率高低顺序;每个单词具备详细的解释,同义词,例句等. 2.支持单词发音,让你学习单词的同时,熟悉发音,训练自己的听力反馈. 3.本组学习,基本上按照1000个单词一个分组,让你可以分阶段的去学习,复习,牢固的掌握. 4.因为是内置词典,所以App不需要访问网络,节约流量的同时,也省去了网络不稳定的烦恼,可以快速的在手机上刷单词. 5.详细的统计,让你可以清洗的知晓自己的单词掌握情况,每一刻都充满成就感;自动过滤掉已经学会的单词,让你更有正对性去学习,缩小学习范围.
