ИНФИНИТИВНЫЕ ОБОРОТЫ

Инфинитивный оборот, вводимый предлогом for ( for - phrase ). В этом обороте предлог for + существительное в общем падеже или местоимение в объектном падеже и инфинитив с to образуют смысловое целое, где инфинитив выражает действие, субъектом которого является существительное или местоимение.

for +  somebody  + to + инфинитив

for  + something + to + инфинитив

For the man                             to enter

For everybody                         to see

    (субъект действия инфинитива)

Такие обороты переводятся на русский язык придаточным предложением, подлежащим которого становится субъект действия, а сказуемым – инфинитив. Тип придаточного предложения зависит от функции, выполняемой оборотом в предложении. Чаще всего оборот употребляется в функции обстоятельства. В таком случае придаточное предложение вводится союзом чтобы, для того чтобы:

For this material to be published this year you must have it typed as soon as possible. – Для того чтобы этот материал был опубликован в этом году, вам нужно как можно скорее перепечатать его на машинке.

Оборот с for выступает также в функции других членов предложения:

There isn’t enough time for the material to be published this year. – Недостаточно времени для того, чтобы материал был опубликован в этом году (обстоятельство следствия).

It is quite possible for this material to be published very soon. – Вполне возможно, что этот материал будет очень скоро опубликован (часть составного сказуемого).

The main problem is for this material to be published as soon as possible. – Основная задача состоит в том, чтобы этот материал был как можно скорее опубликован (именная часть сказуемого).

For his thesis to be published this year is out of the question. – He может быть и речи о том, чтобы, его диссертация была опубликована в этом году (подлежащее).

Если оборот является частью составного модального сказуемого, то при переводе на русский язык добавляются слова должен, следует:

This is for the reader to judge. – Об этом должен судить читатель.
