Explain usage and formation of Present Simple tense (affirmative, negative and interrogative) and make up sentences.

PRESENT SIMPLE The Present Simple tense is the most basic tense in English and uses the base form of the verb (except for the verb be). The only change from the base is the addition of s for third person singular.
How do we make the Present Simple tense?
There are two basic structures for the Present Simple:

• 
  1.Positive sentences
  

• 
  2. Negative and question sentences
  

Look at these examples with the main verb like:

From the above table, notice the following points...
For positive sentences:

• 
  There is no auxiliary verb.
  
• 
  We conjugate the main verb by adding s to the third person singular.
  

For negative and question sentences:

• 
  The auxiliary verb (do) is conjugated in the Present Simple: do, does
  
• 
  The main verb is invariable in base form: base
  
• 
  For negative sentences, we insert not between the auxiliary verb and the main verb.
  
• 
  For question sentences, we exchange the subject and the auxiliary verb.
  

Emphatic do
Normally, for positive sentences we do not use the auxiliary verb do. But if we want to emphasize (stress) something, we may use it. For example, I do like your dress.
I do apologize. I do like you.
