他发呆地望着窗外的风景。

tā fādāi de wàngzhe chuāngwài de fēngjǐng.

He stared blankly at the scenery outside the window.

看着电视，我不经意地发呆了。

kànzhe diànshì, wǒ bù jīngyì de fādāi le.

I absentmindedly daydreamed while watching TV.

她坐在窗前发呆，不知在想些什么。

tā zuò zài chuāng qián fādāi, bù zhī zài xiǎngxiē shénme.

She sat by the window in a daze, lost in thought.
