Simple Present Tense:

In English, we use the simple present tense structure to denote ongoing actions, activities that we generally do, facts known to everyone, actions taken within a certain period of time, unchanging situations, feelings and situations.

In addition, simple present tense is used when describing planned actions, giving instructions and directions, telling pre-programmed events, and especially in storytelling in children’s books.

Establishing a Positive Sentence With Simple Present Tense:

The only thing we need to be careful about when making a positive sentence with simple present tense is the -s suffix according to the verb structure of third person singular. In addition, auxiliary verb is not used when forming a positive sentence. In the simple present tense structure; ‘Does’ is used for He / She / It, and ‘Do’ is used for I / You / We / They.


Subject + Verb (he / she / it -s) + Object

Sample sentences about positive sentence structure:

  • They go to London every winter.
  • I wonder where he lives.
  • We play computer game every weekend.
  • Jack reads a book every Sunday at coffee bar.

Establishing a negative sentence with Simple Present Tense:

When constructing a negative sentence, ‘not’ is added to the do and does auxiliary verbs. It is written as don’t or doesn’t for short.  In negative sentences, since the auxiliary verb takes the suffix -s, the verb should be used simply.

  • I do not like pizza.
  • He does not go to cinema every weekend.
  • We do not come in work on Sunday.

In the question sentences of this structure, ‘Do and Does’ is used at the beginning of the sentence. Since the auxiliary verb takes the suffix -s in the question sentences, the verb should be used simply.

For examples: What do you think about it?

  • Do you like me?
  • Why do you need it?
