1. <the indicative; it states a fact>

2. <the present perfect; meaning, from some unknown time in the past up until now, the present time. HINT: Add in "recently"

3. "has been" is passive. Note, use the passive if the actor, the person or thing who/that initiates the event (i.e., 'increase') isn't important or is unknown. That is, who increased the profit? Do we know and/or is it even important?

[1] Profit increases.
Simple Present Tense. "increases" functions as a verb. That is, the subject "Profit" does something, it acts.

[2] Profit is increased.
Simple Present Tense. "increased" functions as an adjective, not a verb. That is, "increased" describes the subject "Profit". The subject doesn't do or act. The main verb is "is".

Thank casiopea...

i think i am understand it, but when we use "profit increases" it mean true in general or repeated action? am i right? ... besides that, how to construct a sentence by using "profit increases...." could you construct a sentence for me, please?


If passive i know how to contruct. For an example: profit is increased because of consumers buy a lot"
