Present Simple: used for things which are always true e.g. "I live in Moscow". Present Continuous: used for actions which have duration and are happening either now or 'these days'. Present Simple grammar: negative and questions use auxiliary verb 'do/does' don't/doesn't. Present Continuous grammar: swap auxiliary verb and pronoun to make question: she is singing, is she singing? Not for negative.
