Use the Simple Present to express the idea that an action is repeated or usual. The action can be a habit, a hobby, a daily event, a scheduled event or something that often happens. It can also be something a person often forgets or usually does not do.
- I play tennis.
- She does not play tennis.
- Does he play tennis?
- The train leaves every morning at 8 AM.
- The train does not leave at 9 AM.
- When does the train usually leave?

- Every twelve months, the Earth circles the Sun.
- Does the Sun circle the Earth?
The Present Continuous with words such as "always" or "constantly" expresses the idea that something irritating or shocking often happens. Notice that the meaning is like Simple Present, but with negative emotion. Remember to put the words "always" or "constantly" between "be" and "verb+ing."
- She is always coming to class late.
- He is constantly talking. I wish he would shut up.
- I don't like them because they are always complaining.
