	Penicillin  +  394623 Sat, 21 Jul 07 09:27 AM But I know that in Past Progressive, there must be two clauses conjuncted by "when" or "while". Is that true? If so, what the difference between: - I was thinking. - I have thought. Penicillin Difference Between, Clauses, Present Perfect, Perfect Progressive

	Mister Micawber  +  394638 Sat, 21 Jul 07 09:50 AM I chose my wording carefully to avoid both present perfect and past tenses, Amintnt. You are finished-- finished is a predicate adjective. (The performance was not a finished production -- finished is an attributive adjective.) Mister Micawber Tenses, Predicates, Present Perfect, Past Tenses, Perfect Progressive

Hi, it is difficult to answer, because you should put verbs in example sentences in order to understand how to use them. I am thinking now. That's what I'm doing now. I'm thinking about my new invention. Please don't disturb me, leave me alone. When you came in my room, I was thinking. I was thinking about my new invention. I told you to leave me alone. - Mark? Are you ok? You don't seem to be paying attention to the explanation... - Oh, sorry Mrs. Evilteacher, I was thinking. I was still thinking about that exercise we did earlier. As for "I have thought", it is just a present perfect. It is one of the most difficult things to master. You have to understand the basic difference between the present perfect and the simple past, and then it'll take time and practice to use those verbs correctly. To understand the basic difference, you can search this forum, there is an avalanche of threads about that. Or read about it in a good grammar book for learners. PS: I saw you keep on asking "What the difference". It's "What is the difference" or "What's the difference", you are forgetting the verb "is".

	Penicillin  +  394914 Sat, 21 Jul 07 10:14 PM Firstly, I know that it's "What's the difference" not "What the difference", but I just forgot "is", sorry. So Past Progressive & Present Perfect both indicate that somehing has began in the past and has finished. So what's the difference? Thanks Penicillin Present Perfect, Perfect Progressive
