背背词
背背词用真实的对话和场景来记英文：把原文贴进来，标出要记住的词，回顾时遮住再刮开，想起来了才算记住。
遇到问题或有建议，欢迎发邮件到 yinxingdyx@163.com。方便的话请附上 iPhone 型号、iOS 版本和问题截图。
常见问题
怎么录入一个情景？
在首页点录入，先把原文贴进来，配图可选；点「下一步」后，长按原文选词，拖两头的标记调整范围，标出要记住的部分，每处可以写一句描述或释义，最后保存。
能不能一次性贴进来已经标好的内容？
可以。在原文里把要记住的词用 [[ ]] 括起来，| 后面写释义（可不写），例如：
Could you grab me a [[flat white|澳白，一种奶咖]] on your way in?
点「下一步」会自动标好，在第 2 步确认后保存。录入页的「带标注贴入」里有一段提示词，可以直接复制给 AI，让它按这个格式写。
怎么删除一个情景？
点首页频率分布右边的「共 N 个」进入全部情景，在里面删除；或者回顾时编辑这个情景，在编辑页右上角删除。删除后原文、配图、标注和描述都会删掉，不能恢复。
换手机了，数据怎么办？
背背词自己不用 iCloud，没有账号，也没有云同步，数据只存在设备上。不过 iPhone 的整机备份（设置里的「iCloud 云备份」，或者连电脑备份）会由系统把背背词的数据一起备份；用整机备份恢复新手机时，数据会一起迁移过去。删除应用会清除全部数据，请先确认已有整机备份。
买过永久会员，换手机或重装后怎么找回？
永久会员一次购买、永久有效。在新手机或重装后，打开「设置 → 永久会员」，在弹出的页面点「恢复购买」，登录购买时用的同一个 Apple ID 即可找回。
朗读没有声音？
请检查手机是否开了静音、媒体音量是否调低。朗读使用的是系统语音，可以在 iPhone「设置 → 辅助功能 → 朗读内容 → 声音」里下载更清晰的英文语音。

背背词
背背词 helps you learn English from real conversations and situations: paste in a passage, mark the words you want to remember, and during review they are covered up for you to scratch off once you recall them.
If you run into a problem or have a suggestion, email yinxingdyx@163.com. If you can, please include your iPhone model, iOS version, and a screenshot of the issue.
The app's interface is in Chinese; the Chinese button labels are shown below with English translations.
FAQ
How do I add a situation?
Tap “录入” (Add) on the home screen and paste in the passage; an image is optional. Tap “下一步” (Next), then long-press the text to select words and drag the handles at either end to adjust the range. Mark each part you want to remember, optionally add a description or definition, and save.
Can I paste in text that is already marked?
Yes. Wrap each word to remember in [[ ]], and optionally add a definition after |, for example:
Could you grab me a [[flat white|a coffee with steamed milk]] on your way in?
Tap “下一步” (Next) and the marks are filled in automatically; review them in step 2 and save. “带标注贴入” (Paste with marks) on the add screen has a prompt you can copy and give to an AI so it writes in this format.
How do I delete a situation?
On the home screen, tap “共 N 个” (N total) next to the frequency chart to open the full list and delete it there. You can also edit the situation during review and delete it from the top-right corner of the edit screen. Deleting removes its passage, image, marks, and descriptions permanently.
What happens to my data when I switch phones?
背背词 does not use iCloud itself and has no accounts or cloud sync; your data lives only on your device. However, iPhone's whole-device backup (iCloud Backup in Settings, or a computer backup) includes 背背词's data, handled by the system. When you restore a new phone from that backup, your data comes along. Deleting the app erases all data, so make sure you have a device backup first.
I bought the Lifetime Membership. How do I get it back on a new phone or after reinstalling?
The Lifetime Membership is a one-time purchase that never expires. Open 设置 → 永久会员 (Settings → Lifetime Membership) and tap “恢复购买” (Restore Purchases) on the sheet that appears. Use the same Apple ID you bought it with.
Read aloud makes no sound
Check that your phone isn't in silent mode and that media volume isn't turned down. Read aloud uses the system voice; you can download a clearer English voice in Settings → Accessibility → Spoken Content → Voices.
