Hello [이름]!!   I really, really admire you for researching a lot for our lesson.. I must say that you are really studying very hard and I like that about you… Here are my answers to your question: As an auxiliary verb, 'do' is always followed by the base form of the main verb (source: http://www.learnenglish.de/grammar/verbtodo.html) I was also able to search for a blog about the same thing that you were asking and the student asked the following questions: Should we use the past tense or the present tense of the verb for “Did”? For example the following:Must it be:The drunk man did not even took notice of the notes he gave the waiter.orThe drunk man did not even take notice of the notes he gave the waiter.And the following:"I did give the waiter a tip," the man said.or"I did gave the waiter a tip," the man said. And the answer is this: These are correct:The drunk man did not even take notice of the notes he gave the waiter."I gave the waiter a tip," the man said.For added stress, 'did give' is possible in your second sentence. 'Did' shows the past tense, and with the operator (do, does, did) we use the infinitive (or dictionary form) of the main verb. So as a general rule, every time we use ‘do, does and did’ the following verb must always be in its simplest form regardless if the sentence is positive or negative.   So for your question, ‘She didn’t dance’ is the correct sentence. As stated above, ‘did’ already shows the past tense so we don’t have to convert ‘dance’ to its past form. On the other hand, the verb “to have” is used as an auxiliary verb to help other verbs create the perfect tense - auxiliary verb ‘have’ + [past participle]. For example, “I have studied English for five years;” or “I have never been to America.” "I have eaten."   T.
