啸声

wǒ men tīng dào le pēn qì jī cóng tóu dǐng fēi guò shí de xiào shēng

我们听到了喷气机从头顶飞过时的啸声。

We could hear the whistle of the jets as they passed overhead.

fēng chuān guò shù lín fā chū xiào shēng jī guān qiāng zǐ dàn de jiān xiào shēng

风穿过树林发出啸声，机关枪子弹的尖啸声。

The wind moaned through the trees ,and the zing of the passing bullet.
