一起来背单词吧! 平时看文献、写论文都离不开英语,词汇量一直是个绕不过去的坎。市面上背单词的 App 不少,扇贝、百词斩、墨墨之类的我也都用过,但是总有些地方不太舒服,得登录、有广告、打卡提醒烦人,还老是惦记着你的数据。作为一个喜欢自己重复造轮子的让,我写了一个背单词的网站,自己需要什么功能就写什么功能。 纯静态网站,部署在 GitHub Pages 上,数据全部存在你自己的浏览器里,这可能也是我最喜欢的服务部署方式了哈哈哈。地址:[jiaoyuan.org/recite]( https://jiaoyuan.org/recite/),源码在 [GitHub]( https://github.com/imjiaoyuan/recite)。 ## 一次完整的背诵流程 打开首页,是一排词表卡片,每个词表一张。卡片上写着总词数、今天到期要复习的词有多少、还能新背几个,下面一条进度条显示你背到哪了。想背哪个点进去就行。 每张卡片先是正面:英文单词、音标、词性,点一下单词或小喇叭可以发音。你在脑子里想过意思之后,按空格(或点按钮)翻开,背面是中文翻译、英文释义和一条例句。
