The river takes a headlong plunge into a maelstrom of rocks and boulders.

河水急， 一个漂砾的漩涡中。

The soldiers made a headlong rush for cover.

士兵们顾一切冲向掩蔽所。

He fell headlong and landed on his face.

他脸朝一头栽到地上。

The rhino charged headlong towards us.

犀牛急速地向我们冲来。

He rushed headlong into marriage.

他仓促轻率地结了婚。
