​"Shall" is used as a future auxiliary only for the first singular and plural pronouns (I and We). Although i more common to use "will".

​Also, in U.K it is used as a verb to offer our help to someone, for example: "Shall I help you with the bags, madam?"

​There are two auxiliaries to build present sentences: "do" and "does".

Remember that "does" is only used in the third singular person, while "do" is used in the other pronouns.

​

The verb to be in the present means "ser" and "estar", while when the tense changes to the past we use "was" and "were" being in Spanish "fui" and "estaba".

Its use will depend on the pronoun that is in the sentence.
