昨天我度过了我三十岁生日。

I was thirty on my last birthday.

三万三千人认为星期四是他们三十岁生日。

Thirty-three thousand people think that Thursday is their thirtieth birthday.

在她三十岁生日时，他们在她的办公桌上放了一个玩具皇冠，上面用擦不掉的记号笔歪歪扭扭写着“啮齿动物女皇”。

The Rodent Queen—on her thirtieth birthday, they had left a toy crown on her desk, the words scrawled on with permanent marker.

我们驶过黝黑的铁桥时她苍白的脸懒懒地靠在我上衣的肩上，她紧紧握住我的手，驱散了三十岁生日的巨大冲击。

As we passed over the dark bridge her wan face fell lazily against my coat's shoulder and the formidable stroke of thirty died away with the reassuring pressure of her hand.
