擦破

Jack skinned his knee when he fell.

杰克跌倒时膝盖破了。

I barked my shin on a tree stump.

我磕到了树桩上，胫破了。

The boy fell and scraped the skin off his knee.

这男孩摔了, 破了膝盖上。

He skinned his knees when fell.

摔倒时破了膝肤。

He boohooed when he skinned his knee.

当膝盖破时, 大声地哭了起来。

The bullet merely creased his shoulder.

子弹只不过破了肩肤。
