Perfect progressive/continuous tense have:
have/has/had + been + present participle
Present perfect continuous:
I have been waiting for two hours. She has been waiting for two hours.
Past perfect continuous:
We had been waiting for two hours. She had been waiting for two hours.
Past perfect has the form - had + past participle.Jon had eaten the cake.This is a past perfect active sentence. We can see who or what did the action of the verb (the subject - Jon)Passive tenses have the form - be verb + past participleThe cake had been eaten. This is a past perfect passive sentence. Notice we don't know who or what ate the cake.In passive sentences the subject of the sentence is not usually given. I you want to say who or what does the action of the verb then add - by + noun (phrase).The cake had been eaten by Jon.
As far as I know all languages have aspects, which are past, present and future. Sadly, if you're learning (or teaching) English life is not that easy. The past aspect has 4 tenses: past simple past continuous past perfect past perfect continuous The present aspect has 4 tenses: present simple present continuous present perfect present perfect continuous The future aspect has 6: 'timetable' future 'diary' future 'going to' future future 'will' future perfect future perfect continuous But then you have the modals which talk about future possibilities / probabilities. I'm sure I haven't remembered everything but as you can see, eight doesn't even come close.
For regular verbs the past participle is formed by adding -ed to the basic form. eg walk = walked For irregular verbs the apst participle is formed in different ways eg know = known come = came drink = drunk The past participle is used in perfect tenses: present perfect = has walked / have waited past perfect = had come The past participle is used in passive tenses: am know - is played - are drunk - was eaten - were found
Present perfect continuous is formed by - have / has been verb + ing.have been waiting.But know is a state verb and state verbs are not usually used in the continuous form eg knowing.So probably you would never use have been knowing.I have been knowing him for 15 years is not correct.
the importance of studying the past participle of verb, is to know whether it is a helping verb + a main verb, in that case you are also studying the perfect tense of verb in which it is really important in making a sentence or phrase and a paragraph.....:P ♥♥♥ Hope this helps :)
Uninflected verbs retain the same spellings in all tenses, except in the progressive form.

No. If that is done the person reading it won't know if what is written takes place in the past, present, or future. The sentence wouldn't make sense.

The simple tenses are always one word.
The conjugation will (to be) is part of the future tenses, while the word can is used by itself to mean a present ability, or as an auxiliary verb.Will and shall are used in :the future tense of to be (I am, I was, I will be)the future perfect tense (I shall go, or I will go)the future perfect progressive tense (I will be going)The auxiliary verb "can" is used with the infinitive verb form (without to) to indicate an ability to perform the action. (e.g. I know how to drive, therefore I can drive.) The past tense or conditional tense is "could".*Most grammaticists insist on using "may" for permission, so the expression "can I get the ball" would ask about your ability to get it, not whether you were allowed to.
Don't assume he's perfect when you hardly even know him.
Present perfect continuous is formed by - have / has been verb + ing.have been waiting.But know is a state verb and state verbs are not usually used in the continuous form eg knowing.So probably you would never use have been knowing.I have been knowing him for 15 years is not correct.
We know about past tenses because we read and learn about them in books.
I don't know how to use the word "progress" in a sentence. Can you give me a sentence with the word "progress "?
Many authors have written books describing a utopia, but we all know that there's no such thing as a perfect place.
