Question

MODAL VERBS: SHOULD AND MUST
Para oferecer conselhos ou dar sugestões a outras pessoas, use sempre should/shouldn't. O must,
para obrigações, até pode ser usado como conselho, mas teria um sentido mais forte.

Should (deveria)
É usado quando se quer sugerir que alguém faça algo, por exemplo:
Afirmativa: You’re tired. You should go to bed. (Você está cansado)
Negativa: You should not go to sleep so late. (Você não deveria dormir tão tarde)
Interrogativa: Should I tell her? (Devo contar para ela?)

Must (deve)
Esse é um dos Modal Verbs utilizados na língua inglesa para expressar uma opinião ou constatação sobre algo que se
acredita ser verdade.
Veja:
Afirmativa: I must study hard for the math test. (Eu tenho que estudar muito para o teste de matemática)
Negativa: You must not (mustn’t) eat chocolate. (Você não deve comer chocolate)
Interrogativa: Must he go to the doctor? (Ele deve ir ao médico?)
