砰砰

I hear someone is pounding at the door.

听到有人在砰砰敲门。

The planes bam med against the deck of the aircraft carrier.

飞机砰砰地冲撞航空母舰的甲板。

The shutters thumped the wall in the wind.

在风中百叶窗砰砰地碰在墙上。

His heart bounded with excitement.

他兴奋得心头砰砰直跳。

I tapped the melon lightly, the way my mother does in the supermarket, listening for the hollow sound of the freshness: Pung, pung.

像母在市场挑瓜那样，也在瓜上轻轻地敲了敲，听里面有没有空洞洞的瓜熟的声音。果然传来“砰砰”的回声。
