Сочетание модальных глаголов с инфинитивом в страдательном залоге

Сочетание модального глагола can, may, must, should и др. переводится на русский язык словами ‘можно’, ‘может’, ‘нужно’, ‘должен’, ‘следует’ плюс глагол в неопределенной форме: The metal can be strengthened by fibres ‘Металл можно укрепить волокном’.

В отрицательной форме модальные глаголы can, may с инфинитивом страдательного залога переводится как ‘нельзя’, а must, should – ‘не следует’: This instrument cannot be taken without рermission ‘Этот прибор нельзя брать без разрешения’; The instruments shouldn'tbe left plugged in ‘Инструменты не следует оставлять включенными в сеть’.

Сочетание модальных глаголов с перфектным инфинитивом

Модальные глаголы may и must в сочетании с перфектным инфинитивом выражают предположение, относящееся к прошлому, причем may переводится модальным словом ‘возможно’, а must выражает большую степень вероятности и перевoдится как ‘должно быть’: There must have been some mistakes in the calculations ‘В расчетах, должно быть, были ошибки’.

Перфектный инфинитив в сочетании с модальным глаголами could, should, must, ought выражают действие, которое могло бы произойти, но не состоялось. В таких предложениях содержится элемент критики и упрека: You should have checked the instrument before you started the work ‘Вам следовало проверить прибор до того, как вы начали работать’.

Эквиваленты модальных глаголов

1. Модальные глаголы не имеют исходной формы – инфинитива, а значит, не могут образовывать сложных форм (со вспомогательными глаголами, например будущее время) и производных форм (например, причастие). Поэтому для образования таких форм служат эквиваленты, которые имеют инфинитив и могут образовывать любые формы, любого временного значения и наклонения.

Слова, используемые для замены модальных глаголов сап и may, передают лексическое содержание модальных глаголов: сап – to be able (able ‘способный’); may – to be allowed (to allow ‘разрешать’).

За заменителями модальных глаголов всегда следует инфинитив смыслового глагола с частицей to,на­пример: We shall be able to correct the program ‘Мы сможем исправить эту программу’; He was allowed to perform the operation ‘Ему разрешили сделать эту операцию’ (или: ‘Он смог сделать эту операцию’).

Модальный глагол must имеет два эквивалента to be и to have. Глагол must и его эквиваленты to be и to have можно переводить оди­наково – словом ‘должен’,однако они имеют разные от­тенки в значении и поэтому во многих случаях при пе­реводе рекомендуется использовать эквиваленты, более точно передающие их содержание в контексте:

- to be(в буд. времени не употребляется) обозначает заранее предусмотренное, ожидаемое долженствование (в соответствии с планом, договоренностью): I must go to the conference ‘Я должен (мне нужно) по­ехать на эту конференцию’; I am to go to the conference ‘Я обязан (мне предстоит) поехать на эту конферен­цию (должен по плану, по договоренности)’.

- to haveобозначает вынужденное долженствование (в соответствии с изменившимися обстоятельствами) и обычно переводится как ‘вынужден’,‘приходится’: I have to go to the conference ‘Я вынужден (мне приходится) поехать на эту кон­ференцию’ (должен вместо Н., который заболел).
