听以下短文一遍，给你50秒钟的时间准备，然后模仿朗读。当听到“开始录音”的信号后，立即在50秒钟内朗读短文，当听到要求“停止录音”的信号时，应立即中止朗读。

The sun comes up, I start my day.

I get my broom and I’m on my way.

I clean up things that people drop,

From dawn to dusk, I never stop.

I make the streets clean,

And help keep our city green.

Night is falling, the sky is dark.

The only sounds are dogs that bark.

We drive along the streets all night.

To stop thieves and those who fight.

It’s dangerous, but we’re brave.

We help keep our city safe.
