健康的牙齿

字幕原文

Mai is five years old, 麦五岁了，

and her mother wants her to take good care of her teeth. 她的妈妈希望她好好爱护牙齿。

The rule is simple: brush and floss twice a day. 规则很简单：每天刷牙和使用牙线两次。

In fact, in their house, teeth must be brushed before Mai gets her bedtime story. 事实上，在他们家，麦必须在听睡前故事之前刷牙。

Mai is a careful brusher. 麦刷牙很仔细。

She brushes every tooth, 她刷每一颗牙齿，

up and down, 上上下下，

front to back, 前前后后，

even reaching the molars way in the back. 甚至刷到最里面的磨牙。

Then she flosses between each one. 然后她用牙线清洁每颗牙齿之间。

And she never rushes. 她从不匆忙。

Her routine lasts two to three minutes — 她的日常程序持续两到三分钟——

exactly as long as it takes to sing the ABC song. 正好是唱完《字母歌》的时间。

So that is what Mai does: 所以麦就是这样做的：

she hums it quietly to herself, 她悄悄地哼唱着，

and when the song ends, 当歌曲结束时，

she knows she is done. 她就知道自己完成了。

A clean smile, set to a little song. 一个干净的笑容，伴随着一首小歌。
