TENSES:
basically express the time at which something happens. The verb changes to show when something takes place (This is a generalization as tenses can also be used to express more complex things).

This can be used to talk about timetables, e.g. ‘The plane leaves at 10.30’.
It can also express habit, e.g. ‘He eats breakfast at 6am every day’.
General truths e.g. ‘She works for the government’.
Permanent states e.g. ‘She works for the government’.
Reactions/immediate thoughts e.g. ‘That dress looks nice’.

Present Continuous:
This can be to talk about Future plans e.g. ‘ I am having a party on Friday’
An action in progress at the moment of speaking e.g. ‘ He is reading a book’.
Temporary actions or states e.g. ‘ She is living in New York until Spring’.

Conditionals:
These are used when you need to talk about possible situations and their consequences.

Subjects and Objects:
Subjects in sentences are the person/s or the thing which does the action (verb) e.g.

Direct Objects in sentences are person/s or things that the action affects directly e.g.
