Use the simple present (and not the present continuous) to express a present habitual action.
Use the present continuous to express a habitual action with the word always or with a verb denoting a continuous state: He is always talking in class; He is living in London.
Don't use must and ought to as past tenses. To express a past duty (which wasn't done) use the perfect infinitive without to after ought to or should, or expressions such as had to, was obliged to.
In indirect speech use must and ought to as past tenses: He said he must do it.
If you begin with a verb referring to past time, keep the verb forms in the past. The same rule applies to tenses throughout a composition.
If we are speaking of an action just finished, we must use the present perfect instead of the simple past tense. For example, immediately after the clock strikes, we shouldn't say The clock struck, but The clock has struck.
