  Does my dad work in a supermarket?
( se utiliza does  en afirmativa y doesn't en negativa en presente simple para los sujetos He,She,It, además se quita la -S o -ES al verbo )

3.She's helping me with my homework.
aqui es presente continuo/progresivo( es un tiempo que esta formado por el to be + verbo acabado en -ING por lo tanto no se pone do,does/don't, doesn't)
  She isn't helping me with my homework.
  Is she helping me with my homework?
En las negativas se añade not al verbo to be >>>. is not= isn't
                                                                                     .are not>> aren't
En las preguntas  la estructura es :                                                                                      be(am,is,are) + sujeto + verbo en -ing +complementos.
