Zero Conditional and my comment

We use the Zero Conditional when the result of the condition is always true

If+ Simple Present+ Simple Present

for example: If I'm late for class, my professor gets angry

We do not use a comma before if

for example: I feel happy if I eat chocolate


My comment

In this class I learnt more about conditionals. In the first exercise I had 4 correct answers because I was a little confused with some rules but is not very complicated for me.
I have to study some details. I haven't any question for today.
