Verbs - Simple Present Tense

Alright then students, today I would like to share about simple present tense. Before that, I really love to tell you this. Do yo know why English has lots of tenses? Simple Present Tense, Simple Past Tense, Present Continuous, Past Continuous, Future Tense and so on? Well, this is what my lecturer shared with me in one of the lesson. He said that

"English people really values time. That is why English people takes time in consideration whenever they want to construct a sentence"

Basically that is what he meant. I could not remember the exact words though.. sorry for that :)

Okay now, Simple Present Tense. According to this one book that I really love to refer, 'Correct your English Errors' by Tim Collins.

In this book, Collins explain that we use simple present tense to talk about:

1. Things that are always true
    e.g:Cats hate water

2. Things that happen regularly
    e.g: School starts in fall

3. Habits and routines
    e.g: I brush my teeth everyday

4. Future actions that are part of a schedule
    My train leaves at 5.21 P.M.
