Correlation between Russian and English - part 8 - Recap of correlation scheme This is a small recap of mine understanding of English basic rules. The most important thing that you must learn perfect tense. I don't know how you can handle without Совершенной формы глагола (Perfect tense) in Russian, and I don’t get, why we were explained that it is difficult and not frequent form of verb. Additional thing that you are highly likely to use - progressive tense, so i marked it yellow, same thing for passive voice. Perfect continuous I have marked in red, these colors I had picked up for difficulty since they were described through other parts of speech.
