Hello! I really want to learn English Tenses very well, but I have difficulties in understanding Present & Past Tenses (Present/Past Simple/Continuous/Perect). Can anyone help me?
You need to study them. Find an English teacher in your town. You can also study online or at home using good English language course books. The subject is too wide for us to teach you here. If you want to post some complete sentences using the tenses, we can try to see what is confusing you.
Note my amendments above. There is no reason to capitalise the word "tense" or the names of the tenses.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
