Here’s a simple tip for using the English past tense. The past tense of drink is ‘drank’ (not drunk) and the past tense of eat is ‘ate’.
If you want to tell a story about what you did yesterday or last weekend, you might want to talk about your time eating out at a restaurant. To do so, you would use the simple past tense of drink and eat. So when your English teacher asks you what you did last Saturday, you can answer:
I ate pizza with my friends.
I drank some beer with my pals.
