Grammar and Using do, does and did

 Study the following sentences. They are spoken by Janaki and Surendra in the market.
·         I don’t find it a very enjoyable place.
·         I didn’t say I will come here every day.
·         But that doesn’t mean you should sell rotten vegetables.
All the sentences above are ‘negative’ sentences.

(at the doctor’s), we discused one way of forming negatives. The examples were :
I haven’t been feeling well lately.
We aren’t ready.
They won’t call us back.
This can’t be done easily.

In these examples, we added not (n’t) directly to verbs.
Positive : I have...
Negative : I have not (haven’t)..
Positive : We are..
Negative : We are not (aren’t)..
Positive : They will..
Negative : The will not (won’t)..
Positive : This can..
Negative : This cannot (can’t)..

We can add not (n’t) directly to the verb, if the verb is one of the following.

Am      have    do        shall      can        must
Is         has      does     will       could     ought
Are      had     did       should   may       need
Was                            would   might     dare
Were                                                      used (to)

These verbs are called ‘helping verbs’

But look at the following sentences.
I find it a very enjoyable place.
I said I would come here very day.
But that means you should...

The verbs in these sentences are : find, said, and means. Look at the list of ‘helping verbs’ in the box above. Are these verb ‘helping verbs’? No, they are not. So, we cannot add not (n’t) directly to the verbs. What do we do, then, to form negative?

Positive                                                  Negative
I find...                                                    I do not (don’t) find...
....that means..                                   ...that does not (doesn’t) mean...
I said...                                                    I did not (didn’t) say...

We have used do, does and did, and added not to them. Study a few more examples:
Positive : We know the answer.
Negative : We do not (don’t) know the answer.
Positive : She knows how to swim.
Negative : she does not (doesn’t) know how to swim.
Positive : You tried very hard.
Negative : You did not (didn’t) try very hard.

Turn the following sentences into the negative.

  • I like the rainy season.
  • He work in a factory.
  • We came back early last night.
  • I walked in the rain.
  • She wears jeans.
