首先,向大家介绍一位爱牙小标兵——Frazzle。
A tooth is one of your teeth. Teeth are in your mouth and are used for biting and chewing.
“A tooth”表示一颗牙齿。牙齿是在口腔里负责啃咬和咀嚼的。
Frazzle is brushing his teeth. He has one toothbrush for each tooth.
Frazzle正在刷牙,他为每颗牙齿都准备了一支牙刷!
然后,我们再来认识一下刷牙必不可少的工具——Toothbrush 牙刷
A brush is a tool made of bristles fastened to a handle.
刷子是一种把刷毛固定在手柄一端上的工具。
Ernie wants to paint the hallway. He has a can of paint. Which brush is better for him?
Ernie想粉刷一下走廊,他有一罐油漆,选哪一只刷子才对呢?
Bert wants to clean his teeth. He has some toothpaste. Which brush is better for him?

当然是Toothbrush(牙刷)啦!
