Unit 16: Present Indefinite Tense (Negative and Interrogative)
In this lesson, we shall learn:

* Negative and Interrogative structure of Present Indefinite Tense.
* Use of Do and Does.

Urdu Explanation:



English Explanation:




Negative Structure of Present Indefinite Tense.

S + DO / DOES + NOT + FIRST FORM OF A VERB + O.
We already know what is Present Indefinite and how to use Present Indefinite Tense. In Unit 14 We studied the usage of Present Indefinite Tense and learnt only Affirmative usage of Present Indefinite Tense.

The above is Negative structure Of Present Indefinite Tense, you can see that the structure starts with Subject , plus Do or Does(only in case of third person singular.If you don't know about persons, you can visit Unit 12) then (Not) which makes any sentence negative and then first form of the verb and object.Remember that Does is used only in case of Third Person Singular.

e.g.
He does not play cricket. (He third person singular) I do not play cricket. (I first person singular)

One more thing to remember is not to add (s or es) in case of third person singular with first form of verb in Negative sentences.

e.g.
Correct: He does not play cricket.
Incorrect: He does not plays cricket.

Interrogative Structure of Present Indefinite Tense.

DO / DOES + S + FIRST FORM OF A VERB + O.

The usual rule of making a sentence Interrogative in English is to place the helping verbs before the subject and the sentence turns into a question.In Present Indefinite Tense, the helping verbs are Do/Does. That is why you can see the structure starts with Do / Does, I hope you remember when to use Do and When to use Does.Do not add s/es with first form of a verb.

e.g.
Do you go to school? Does she play cricket? e.g.
Correct: Does he go to school? Incorrect: Does he goes to school?
