Well every body, if we see from the tittle above means we are still talking about simple future tense but maybe “ shall “ is not really familiar if we compare with the auxilary verb “ will “ or “ tobe going to “. As we know we use auxilary verb will in American style and we can use it for all subjects in English, that is why “ will “ is more familiar than “ shall “. “ Shall “ is used in British style and it is only for subject “ I “ and “ We “.
- I shall visit my grand mother who is hospitalized in M. Hoesin Palembang tonight
- I shall not hurt you if you do not have bad intention to me
- We shall consume vitamins to make our body fit
- Shall we help them ?
Different from “ will “, we often use “ shall “ in formal situation and it is usually to express obligation.
