Crows cawed from the poplar trees overhead.

白杨树上的乌鸦在上空呱呱乱叫。

I could hear croaking of the frogs .

能听到青蛙呱呱的叫。

I could hear the staccato clatter of Mexican from the next table.

能听见邻桌有人用墨西语续续呱呱的谈。

I've been taking lessons in tracking from this really neat Indian guide.

向这位顶呱呱的印第安人向导学习跟踪。

The crow croaked disaster.

乌鸦呱呱叫预报灾难。
