The bamboo whipped back and hit me in the face.

那竹子突然弹回打我的脸上。

She bounced the ball against the wall.

她把球掷到墙上让它弹回来。

The ball struck the wall and bounded back to me.

球碰到墙又向我弹回来。

The ball sprang back and hit him.

球弹回打他身上。

The ball rebounded from the wall.

球从墙上弹回来。

The ball bounded from the wall.

球从墙上弹回。

My comments: Then comes a tehee! The spider bounces back.

然后，扑哧一声！蜘蛛突然纵身弹回了。

The door sprang to.

门弹回关上。
