### 5/5 — 非常科学，世界上最好的单词软件

*2026-08-14*

我给满分

### 1/5 — 小疑问

*2026-08-09*

怎么保留或者查看之前看过的阅读文章？每天更新后没有阅读记录吗？

### 5/5 — 非常好用

*2026-08-03*

我觉得这个很好用 可以沉浸式刷单词 很适合四六级和考研

### 5/5 — 希望加上文章可以收藏的功能

*2026-07-26*

这样看完一篇文章还可以第二天再看一遍，这样更有效

### 5/5 — 很好看，单词释义也很详细

*2026-07-15*

英文释义非常有用。

### 4/5 — 希望可以及时更新词书

*2026-07-11*

软件还是很好用的！但是能不能及时更新某些词书，比如说红宝书每年的单词都不一样，希望可以及时更新拜托了。

### 4/5 — 建议

*2026-05-06*

希望可以每个周添加一次全例句听写，在后续的抽查上可以将完全记住的单词考察时态和变形 ，希望在目前的这个阅读界面可以出一个收藏文章和文章填空，

### 5/5 — 强烈建议加上图片功能

*2026-03-13*

单词配合场景图，基本秒记忆名词，用例句其实对初学者不友好，很多词汇不认识，只觉得很累。但是加上场景图，可以迅速破冰一个单词。

### 5/5 — 修改意见

*2025-11-23*

以前单词下放的进度条有倒计时，根据停留时间长度判断掌握程度，现在那个进度条变成了单词进度条，希望改成以前的，现在的总让人感觉很焦虑

### 5/5 — Very nice

*2025-11-06*

Very nice
