Present Tense
A. Meaning Simple Present:
1)The simple present tense is used to describe an action or an idea that is always true, such as scientific facts and physical laws.

b)The average person breaths
c)The world is round.
These are facts that were, are and always will be true, unless scientists discover otherwise.
2)You can also use simple present to describe something that happens habitually. This means that you can use adverbs such as always, usually, often, sometimes ,never, etc.If you feel uncertain whether you should use the simple present tense or not, ask yourself if you can add one of these adverbs and the sentence still makes sense.
