I have compiled the Complete Tense Structure for all the Tenses. Past, Present and Future. Each Tense is divided into The Simple, Continuous (Progressive), Perfect and Perfect Continuous.
Each Tense statement is divided into 4 groups as well i.e. i) the positive statement, ii) the negative statement, iii) the positive question, iv) the negative question
Please note that negative questions are rarely mentioned in most grammar books.
EG. Don\'t you drive to work?
