Expressing “In One Breath / Straight Through” with “yìkǒuqì”

他昨晚回到家以后，几乎没休息，就一口气把剩下的报告全部写完了。

Tā zuówǎn huídào jiā yǐhòu, jīhū méi xiūxi, jiù yìkǒuqì bǎ shèngxià de bàogào quánbù xiě wán le.

After getting home last night, he hardly rested and wrote the rest of the report all in one go.

这本小说我原本只想随便翻翻，没想到越看越想知道后面发生了什么，最后竟然一口气看到了凌晨。

Zhè běn xiǎoshuō wǒ yuánběn zhǐ xiǎng suíbiàn fānfan, méi xiǎngdào yuè kàn yuè xiǎng zhīdào hòumiàn fāshēng le shénme, zuìhòu jìngrán yìkǒuqì kàn dào le língchén.

I originally only wanted to flip through this novel casually, but I became more and more curious about what happened next and ended up reading straight through until dawn.

他把积压在心里很久的话一口气都说了出来，整个人似乎轻松了不少。

Tā bǎ jīyā zài xīnli hěn jiǔ de huà yìkǒuqì dōu shuō le chūlái, zhěng ge rén sìhū qīngsōng le bù shǎo.

He poured out in one breath everything he had kept in his heart for a long time, and he seemed much more relieved afterwards.
