請問老師，你們兩個 You two 和 You both 是不是都正確？

He put them both into his mouth.

We both tried to get the coins.

這兩句話中的both能不能都用two替換？

這個理論是可以的，取決于用詞時候的心態。 如COCA有例句：If housing is an issue,?put?them?two?to a bedroom in low-income public housing。We?two?are the busiest men in the parish.??

Will you sit down with me? And?we?two?will rail against our mistress the world and all our misery.?
