The structure of present simple

We use this structure to explain what you do every day, or in any time of your life, and it's true now. 

Here we have a detail, which is:

With 3rd person we have to put an 's' at the final of the word, for example if you have the verb "work"; for She you should put "She works" and it changes for verbs like; study or play, that have to change 'y' for ies for example: she studies.
