## What is COCA词频单词?

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.

### 1/5 — 怎么搞的，没法自己跳了，右上角的两个功能到一块了，有bug吗

*2025-03-20*

怎么搞的，没法自己跳了，右上角的两个功能到一块了，有bug吗

### 3/5 — 为什么明明背完了一千个单词，外面显示还是500多个

*2023-10-05*

进度条一直停留在第一等级的第560个单词，明明已经背完了一千个，外面进度条还是560

### 4/5 — ？

*2022-09-20*

能不能提供发音选项我想选左边其中一个现在是系统的默认发音像机器一样

### 4/5 — 单词很长的时候，很难点到美式发音

*2022-03-30*

提几点建议：
1.单词太长的时候右边功能栏会挡住单词的美式发音
2.右边功能栏都有什么作用可以简单介绍一下吗？
3.可以不可以出一个收藏夹功能，有的单词想多看几眼

**Developer response:** 已经添加收藏夹功能

### 2/5 — 好坏参半

*2021-07-24*

我只是想要买这个资源，有词汇量分级，很方便。缺点是软件太卡了，技术人员能不能更新一下啊，毕竟花了30大洋呢😂

### 1/5 — 垃圾软件

*2021-03-19*

太垃圾了，花了30块钱，结果还一直弹广告！

### 1/5 — 界面粗制滥造，使用体验不佳

*2020-09-25*

界面非常粗糙，跟上世纪游戏机界面似的，不过作为一个号称背单词的app，UI糙就糙吧。但是单词老是卡顿真得不能忍，就是我点下一个单词，读音一直在变，界面却一直停留在原来的那一页，每次都要退出重新打开才行，这点不能忍。总之，没买的慎重考虑！

### 3/5 — 很一般，经常卡顿，需要优化，另外默认的发音不准，也很难听。

*2020-07-25*

很一般，经常卡顿，需要优化，另外默认的发音不准，也很难听。

### 5/5 — Good

*2020-07-18*

确实很不错，字典齐全，例句精美，确实是值得购买，也算是开发者良苦用心的酬劳了，感觉不亏，希望部分细节能多多改进，继续加油💪

### 4/5 — 功能按钮位置不合理

*2020-06-06*

功能按钮放在右上角无法单手操作，作者能不能考虑放下来，谢谢
