Времена группы Perfect Continuous.

Времена группы Perfect Continuous представляют собой сочетание глагольных форм Perfectи Continuous.

К группе Perfect Continuous относятся три глагольные формы: Present Perfect Continuous, Past Perfect Continuous и Future Perfect Continuous. Все они образуются из вспомогательного глагола to be в форме Present Perfect, Past Perfect или Future Perfect и смыслового глагола в форме первого причастия (Participle I).

Present Perfect Continuous Past Perfect Continuous
  I have been working   he she has been working it   we you have been working they     I he she had been working it we   you they had been working  



The Future Perfect Continuous Tense.



  I shall   he she will it have been working we shall   you they will  


Подобно группе времен Continuous глагольные формы Perfect Continuous обозначают длительноедействие. Это действие всегда охватывает период времени, который предшествует либо моментуречи (для Present Perfect Continuous), либо указанному в предложении моменту в прошлом (для Past Perfect Continuous) или в будущем (для Future Perfect Continuous)



Our scientists and factory workers have been workinghand in hand for many years.

Наши ученые и производственники работают совместно уже много лет.


В подобных случаях Present Perfect Continuous переводится на русский язык глаголом в настоящем времени, причем связь между длительным действием в прошлом и настоящим моментом часто передается в русском языке словом уже.

Look at the plan of our work. It is ready; I have been making it for some hours.

Посмотрите на план нашей работы, он готов; я делала его несколько часов.


В данном примере глагольная форма have been making выражает длительное действие, законченное непосредственно к моменту речи, и переводится на русский язык глаголом в прошедшем времени.

Глагольная форма had been studying (Past Perfect Continuous) выражает длительное действие, протекавшее до указанного момента (before its composition was discovered) и, возможно, продолжавшееся и после этого момента.
