= Questions And Auxiliary Verbs =
== 46. Questions (1) ==

 A. In Questions, we usually put the first auxiliary verb(AV) before the subject(S) 

    t)  S + AV   ->     AV + S
        I can    ->     Can I?
    ex) What can I do?



 B. In simple present questions, we use do/does(do/does) 
    t)  you live  ->  do you live?
    ex) Do you live near here?

    In simple past questions, we use did
    t)  you sold  ->  did you sell?
    ex) Did you sell your car?

    But do not use do/does/did if who/what/which is the subject of the sentence.
    Compare :
    ex1) who object 
         Emma phoned somebody. -> Who did Emma phone?
    ex2) who subject
         Somebody phoned Emma. -> Who phoned Emma?
