擦破

Jack skinned his knee when he fell.

杰克跌倒时盖了皮。

I barked my shin on a tree stump.

我磕到了树桩上，胫了皮。

The boy fell and scraped the skin off his knee.

这男孩摔了一, 了盖上皮。

He skinned his knees when fell.

摔倒时了皮肤。

He boohooed when he skinned his knee.

当盖时, 大声地哭了起来。

The bullet merely creased his shoulder.

子弹只不过了肩皮肤。
