The simple present expresses daily habits, general statements of fact, or situations that exist always, usually, or habitually. The present progressive expresses an activity that is in progress at the time of speaking. It uses "be" verbs like "am, is, are" plus the "-ing" form of the verb. Examples are given to illustrate when to use each tense.
