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.

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).
