1) For 'Permanent' Conditions or Repeated Actions

We use the present simple tense to describe conditions that are relatively unchanging, often-occurring or widely accepted as fact. Common uses include:

• generalising or stating facts;
• describing companies, products and things;
• describing people, their preferences and routines; and
• asking questions about these things.

2) For Schedules and Timetables (general/future time)

We can use the present simple tense to talk about scheduled events or timetables, especially with such verbs as: arrive, be, begin, close, come, end, finish, leave, open, return, and start. If referring to the future with these verbs, we also use a future time expression like at midday, later today, tomorrow, next year, etc.

3) For Showing Status rather than Action

A number of verbs are normally used in the present simple (rather than the present continuous) to describe a state or condition. These “status” verbs include:

• Verbs of description or appearance:

be, appear, contain, consist of, cost, depend on, include

• Verbs of thinking:

believe, doubt, feel, forget, guess, imagine, know, mean, need

• Verbs of the senses:

feel, hear, see, smell, sound, taste

• Verbs of possession:

belong to, have, own, possess

• Verbs of emotion, opinion, feeling:
  

care, dislike, hate, hope, like, love, mind, regret

• Verbs of intent:

agree, intend, promise
