She heard the sirens scream their unearthly wail.

她听见警报器发出可怕的鸣叫。

Lights flashed and sirens screamed.

灯光闪动，警报鸣叫。

Sirens pierced the silence of the night.

警笛声划破了夜晚的宁静。

Ambulances raced by with sirens wailing.

救护车高声鸣笛疾驰而过。

The fire engines were just pulling up, sirens blaring.

救火车刚刚停下，警笛声还在尖利地响着。
