The theory states that the present simple is used for habits or routines, as well as for timetables and programs (such as buses and trains). For example, "I always walk to school" illustrates a routine, and "The lesson starts at 9 o'clock" demonstrates the use of present simple for timetables.

On the other hand, the present continuous is used for actions happening around the time of speaking. The examples "We are having a picnic now" and "We're studying hard these days" show the present continuous in action.

It's worth noting that stative verbs like "believe," "want," and "like" do not have continuous verb forms. For instance, "I want to become a doctor" is correct, while "I'm wanting to become a doctor" is not.

Time adverbs also play a role in indicating tense:

- For present simple, adverbs like "every day/week/month/year," "once/twice a week/year," "usually," and "often" are used.

- For present continuous, adverbs like "now," "at present," "these days," "for the time being," "today," and "at the moment" are employed.
