- Kids shall not enter this room.

Além disso, shall é utilizado para referir-se a algo que irá acontecer ou existir no futuro:

- Shall we dance?

Should:

Should é empregado para indicar uma obrigação, dever ou correção, normalmente quando criticamos as ações de outra pessoa.

Podemos utilizá-lo ao indicar uma opinião pessoal. Em outras palavras: quando desejamos oferecer um conselho a alguém.

- You should call the police.

Should é utilizado para expressar o desejo de que algo tivesse acontecido no passado (mas que não aconteceu) ou um arrependimento.

- They should have come to the party.
