In English, we use different forms of a verb to indicate whether an action or event is about to happen, is happening right now, or has already happened. The latter is the past tense form. Here is one example: If you want to say that you were on a bicycle yesterday, you would use the past tense form of the word ride, which is rode, and you might say, "I rode my bicycle to the store." This would not tell anyone that it happened yesterday, but they would immediately know that is had already happened. There are many books that list verbs and their different forms, but if you have a friend who speaks English well, you can learn a lot from asking them to tell you the correct form when you are speaking. If you need to write in English, though, it is probably better to have a good book to refer to, as well as learning from the people around you. Good luck!
