já musím běžet
I must / I have to run
on nemusí uklízet
he doesn't have to tidy (clean)
my nesmíme hrát
we mustn't play
on musí psát
he must / has to write
ona nemusí jít
she doesn't have to go
já nemusím zpívat
I don't have to sing
moje sestra nesmí tancovat
my sister mustn't dance
naše škola musí vyhrát
our school must /has to win
oni nemusí pít mléko
they don't have to drink milk
ty musíš chodit do školy
you must /have to go to school
