一次

wǒ zhǐ gēn tā jiàn guò yī cì miàn

我只跟她见过一次面。

I've met her only once.

léi shēng gé de yī cì bǐ yī cì jiǔ zhè yì wèi zhe bào fēng yǔ yào guò qu le

雷声隔得一次比一次久，这意味着暴风雨要过去了。

The increasing distance between thunderclaps meant the storm was moving away.

wǒ qù guò nà r yī cì

我去过那儿一次。

I have been there once.
