走过公园的时候，我看到很多孩子在玩。

Zǒuguò gōngyuán de shíhou, wǒ kàndào hěn duō háizi zài wán.

When I walked past the park, I saw many children playing.

只要你走过一次，就不会再迷路了。

Zhǐyào nǐ zǒuguò yí cì, jiù bú huì zài mílù le.

As long as you walk it once, you won’t get lost again.

他走过我身边，却没有看到我。

Tā zǒuguò wǒ shēnbiān, què méiyǒu kàndào wǒ.

He walked past me but didn't see me.
