Hi Akos! In spoken English, the common tenses used are: 1) Simple Present Tense - to talk about routines or facts (e.g. I brush my teeth in the morning) 2) Present Continuous Tense - to talk about things that are happening at that moment (e.g. I am using my computer now) 3) Simple Past Tense - to talk about things that happened in the past at a specified time (e.g. I visited Paris last year) 4) Present Perfect Tense - to talk about things that happened in the past at an unknown time (e.g. I have visited Paris) 5) Simple Future Tense - to talk about future events or plans (e.g. I will watch a movie tomorrow) There are other tenses that we use as well, but these are the most common! I hope this helps! Good luck!

We use all of the tenses. There's no such thing as a "literary tense" in English. If you ignore some tenses and use only a handful of others, your English will never sound natural.
