I have learnt that there are in-fact four present tenses, the: Present Simple - Form: 'I work, you work etc...' (subject = base form [=s/es]) Negative: I don't work, you don't work etc..' (subject + aux verb 'do' + not = base form) Question: 'Do I work? Do you work? etc..' (aux verb 'do' + subject = base form) Usages for this - habitual or routine actions (He goes swimming every week), permanent situations and facts (the sun rises in the East), Commentaries (Ann passes the baton to John who wins the race), directions and instructions (First you go right the straight on), Newspaper headlines, present stories and historical sequence. Present Continuous: this tense is made with the present simple tense of the aux verb 'to be' and the present participle (verb plus -ing working) of the main verb. Affirmation: (subject + aux verb 'be' + verb+ing) - I am learning, you are learning etc... Negative: (subject + aux verb 'be' + not + ver+ing) - I am not learning, he is not learning etc... Question: (aux verb 'be' + subject + verb+ing) - Am I learning, are they learning etc... Usages: Talking about an action that is proper at the time of speaking: \"Please be quiet. I'm watching TV.' To talk about a temporary action that is not necessarily in progress at the time of speaking: \"I am reading a good book at the moment.\
