  2. Can Ana do a good job? Josh __________ (does look, does looks) happier when Ana lets him eat as much ice cream as he wants.
  3. One day when Josh had a stomachache after eating three bowls of ice cream, mom did not believe it, but Ana had to admit, “Yes, he __________ (did eat, did ate) three bowls.”



Three helping verbs “does, do, did” are used to correct a disbelief or to emphasize the truth of a statement. They are used only in affirmative simple present and simple past sentences. The main verb must be a “Do” verb and must be in its base form.

does/do/did + base form of a “Do” verb

  • In Sentence #1, “do” + base form of main verb “babysit” – to correct her friends’ disbelief
  • In Sentence #2, “does” + base form of main verb “look” – to emphasize that Josh looks happy
  • In Sentence #3, “did” + base form of main verb “eat” – to correct mom’s disbelief
