Past Perfect Continuous & Future Perfect / Perfect Continuous Do you really not use Past Perfect Continuous, Future Perfect and Future Perfect Continuous? In that case, what tenses do you use instead? For example, what tenses are used in the UK and the U.S., when you want to say: - I had been reading the book for 3 hours, when he came. - I`ll have read by 6 o`clock tomorrow. - By the New Year she`ll have been working here for 3 years. What tense would you use, if these tenses are not used? Thanks in advance.
