that + подлежащее + инфинитив без to: советы, требования и необходимость.
Rule
Когда мы советуем, требуем, просим или говорим, что что-то необходимо, после that глагол стоит в инфинитиве без to — какое бы ни было подлежащее и в каком бы времени ни стоял главный глагол. Это и есть subjunctive: мы не сообщаем факт, а говорим о том, чего кто-то хочет, требует или советует.
The pattern
verb / adjective + that + subject + base form
The doctor recommended that he rest for a week.
It's vital that everyone be on time.
She insisted that he not tell anyone.
В американском английском — именно так. В британском часто добавляют should: The doctor recommended that he should rest. Оба варианта верны.
Her suggestion that he leave early was a good one.
What looks unusual
No -s
he / she / it + base form
в 3-м лице не добавляем -s
She demanded that he apologise.
The manager requires that she attend.
Be
is / am / are / was / were → be
to be всегда превращается в be
It's important that he be informed.
We ask that you be patient.
Not
not + base form
отрицание без do / does / did
I suggest that he not go alone.
It's crucial that they not be late.
Время главной части ни на что не влияет — после that форма остаётся той же:
He insists that she go.
He insisted that she go.
Common mistakes
