The present simple is very easy to form, we just use the infinitive of the verb. For he/she/it we add an 's' to the infinitive form:
I live You live He /she / it / John lives We live You live They live
Present Simple Use
Present simple has two main uses in English:
1. Things which are always true:
This can include general facts:
'The earth takes 365 days to go around the sun'
Or long term / permanent plans of our own:
'We live in London' 'We have 3 children'
2. Long term habits, things which we do again and again:
'I play tennis every Wednesday evening'
So present simple mainly talks about long term or permanent things, but there are some verbs which are nearly always used in the present simple:
1. Verbs of feelings and emotions. The following verbs usually use the present simple even for short term things:
love / hate / like / enjoy /prefer
'I like tennis' 'I prefer red wine to white wine'
2. Verbs for giving our opinions:
think / believe / feel / understand
'I think that your new shirt looks great!' 'I'm sorry I don't understand the question'
3. Verbs of the senses:
see / look / sound / smell / taste / feel
'You look nice tonight' 'His voice sounds a little bit strange'
Present simple can also be used to talk about the future:
Here present simple talks about official timetabled plans in the future, plans which we cannot change:
'Our plane leaves at 12 o clock'
'The meeting starts at 3pm tomorrow'
