In Paragraphs^x, Present continuous^x, Past perfect^x

Greetings, I have a pretty big favour to ask. I've been struggling with this topic for quite awhile now.It goes without saying that my English "leaves something to be desired". Having in mind the subtle differences that occur from using particular tenses, I have often wondered how...

hello all I will put (write) here all the general forms of the English grammar tenses as I know (understand ) it, I want you to chek it and correct me. Sometimes there is no form (just a speace), I want you to write the general form of the kind of the tense that is detected. I'm so sorry...
