Hello, jgong-- and welcome to English Forums.
The progressive aspect (
-ing form) of verbs works similarly in all tenses, and has a similar relationship to the simple verb forms. Progressive is used to indicate a continuing activity, especially relative to the rest of the sentence:
I study English = generally, an activity I do at unspecified times
I am studying English = now or currently I am actively doing this.
I studied English = a past fact
I was studying English = I was doing this when something else happened:
I was studying English when the earthquake struck.
I will study English = a future fact; sometime in the future I will do this.
I will be studying English = I will be doing this when something else happens:
I will be studying English when you come to pick me up.Another use of progressive aspect is for politeness or to show special interest in the action:
Were you really studying English with your girlfriend last night?
Will you be studying English in school next year, too?I will out of office--
This is no good; it has no verb..
