下课铃一响，同学们都冲出操场去玩。

Xiàkè líng yì xiǎng, tóngxuémen dōu chōngchū cāochǎng qù wán.

As soon as the class bell rang, the students all rushed out to the playground to play.

当铃响起时，学生们纷纷走进教室。

Dāng líng xiǎng qǐ shí, xuéshēngmen fēnfēn zǒujìn jiàoshì.

When the bell rings, the students enter the classroom one after another.

每天早上听到闹钟铃声后，我才会起床。

Měitiān zǎoshang tīng dào nàozhōng língshēng hòu, wǒ cái huì qǐchuáng.

I only get up after hearing the alarm clock ring every morning.
