Student or Learner
This is my first time to post message and here is a question relate to auxiliary.
When should I using do, does and when should I using am, are, is?
Thanks for your time.
Do also can be used to emphasize in: "I do like her"...and Do/Does are used in place of other verbs in replying Yes/No questions: "Do you understand what I am saying?" _ "Yes, I do!".( NOT 'Yes, I understand"
2, Am, Are and Is come from verb To Be.
I will put it this easy way for you to understand:
We put these verbs at the beginning of an Yes/No question :
"Am I your friend?" ( Am always goes with I )
"Are you/We/They...Chinese ?" ( Chinese here is the Complement part in the sentence. The complement could be a Noun, Pronoun, an Adjective, Adverb of place, a past participle Adjective or a Present participle Adjective )
" Is He/She/It....? Yes, he / she/ it is or No, he / she/ it isn't.
