投喂东西用英文怎么说

"To feed something" is the Engpsh phrase that means "to give food or other sustenance to something or someone."

Here are some example sentences:

I need to feed the cat before I leave for work. (我需要在出门上班前喂一下猫。)
The baby is hungry, so I'm going to feed him some milk. (这个婴儿饿了，我要给他喂点牛奶。)
The plants need to be fed with water every day. (这些植物每天都需要浇水。)

The word "feed" comes from the Old Engpsh word "fēdan," which means "to give food to." It has been used in Engpsh for hundreds of years to describe the act of providing sustenance to another pving being.
