I want to ask that how to use do and does in our sentences?
when we should use do and when we should use does?
Could you give us a few examples of the sentences you're having trouble with? For example,
Inversion: Do you?, Does she?
Emphatic: You do like coffee. She does listen to music.
DO-Insertion: I eat cake => Do you eat cake?
Tags: They want cake, don't they? He has a cold, hasn't he/doesn't he?
Let us know.
