Tense

The three tenses mention in the previous slides can further be divided into sub parts. These sub parts include:

Simple Continuous

Perfect Perfect

Continuous

The concept of tense in English is a method that we use to refer to time - past, present and future. 
Tenses can be divided into three parts:
Present Tense
Past Tense
Future Tense

Present Tense can be defined as an expression for an activity that is currently in action or is habitually performed. It is used for a state that generally exists or is currently ongoing.

The simple present tense is when you use a verb to tell about things that happen continually in the present, like every day, every week, or every month. We use the simple present tense for anything that happens often or is factual. 

If Positive sentence:

Subject + Base Form(V1)+’s’ or ‘es’ + rest of the sentence

For eg.  He eats apples daily.

If negative sentence:

Subject + do not / does not + base form + rest of the sentence

For eg. He does not eat apples daily.

The present continuous verb tense indicates that an action or condition is happening now, frequently, and may continue into the future.

Formula: Subject + am, is, are + V1  + ing + object

For eg: She is eating food.
