老师让我们重复读这段课文三遍。

Lǎoshī ràng wǒmen chóngfù dú zhè duàn kèwén sān biàn.

The teacher asked us to read this passage of the text aloud three times.

你能重复一下刚才说的话吗？我没听清。

Nǐ néng chóngfù yíxià gāngcái shuō de huà ma? Wǒ méi tīngqīng.

Could you repeat what you just said? I didn't hear it clearly.

历史总是在不断地重复，我们要从中吸取教训。

Lìshǐ zǒngshì zài búduàn de chóngfù, wǒmen yào cóngzhōng xīqǔ jiàoxun.

History is always repeating itself; we must learn lessons from it.
