    優(yōu)質(zhì)解答
    (1) must not = prohibition (it is not allowed)
    (a) The teams[ must not] have more than 11 players on the field during a match.
    (b) Players [must not] wear anything which might injure another player.
    (2) need not = option (it is not necessary) = do not have to
    (a) But there [need not] even be 11 players playing for each team.
    (b) Players [need not/do not have to] play the ball with their feet only.
