擦破

Jack skinned his knee when he fell.

杰克跌倒时膝盖擦破。

I barked my shin on a tree stump.

磕到树桩上，胫部擦破。

The boy fell and scraped the skin off his knee.

这男孩摔一跤, 擦破膝盖上的。

He skinned his knees when fell.

摔倒时擦破膝部的肤。

He boohooed when he skinned his knee.

当的膝盖擦破时, 大声地哭起来。

The bullet merely creased his shoulder.

不过擦破肩部的肤。
