How long did she drive or How long did she drove?

I am little confused here.
I am almost always using verb in present when I use did or didn't.

Did she catch any fish yesterday?

But is it ok? Is it possible to use:
Did she caught any fish yesterday?

Or:
Didn't she drive yellow car?
Didn't she drove yellow car?

Do you ever use verb in past when you use Did or Didn't? If yes, in which case?

  • You are using the base form of the verb, which is not present or past or any tense.
  • The words did and didn't already carry the information that it is past tense, so only the unchanged base form (the dictionary form) is used with did and didn't (and with do, don't, does, and doesn't ).

When you use the helping verb "do," the tense inflection is in this verb, not the main verb. The main verb is always in the infinitive (base) form.

The base form of the main verb is also used with the modal helping verbs: (can, could, may, might, would, will, ought to)
