benjamin dohThe distinctions between the Past and the Present Tense depend on the type of the word(s) used,it sometimes goes with the word "ed" but not always.
I suggest you familiarize yourself with books that give you a clear distinction between the two or a lot of reading would do, please do not try to memorize the words, just read and understand the content.
