Решение
Модель: You shouldn't + инфинитив, unless + условие. Shouldn't — «не следует»; unless [ənˈles] — «если не», «разве что». В предложении с unless глагол стоит в утвердительной форме (сама частица уже несёт отрицание). Подставляем слова.
. You shouldn't take an aspirin, unless you have a headache. — Не следует принимать аспирин, кроме случая, когда у тебя болит голова.
. You shouldn't sit around doing nothing, unless you're on holiday. — Не надо сидеть без дела, разве что в отпуске.
. You shouldn't throw a birthday party, unless you have time to make preparations. — Не стоит устраивать вечеринку, если нет времени подготовиться.
. You shouldn't apologise, unless you are the one to blame. — Не извиняйся, если ты не виноват.
Здесь be в форме you are / you're, have — you have.
