6. But There’s
More!
Using the four principal parts to conjugate six
tenses, you might also add two forms:
• Progressive form shows continuous
(continuing to progress) action; uses being
verbs.
• Emphatic form shows emphasis in the present
and past; uses “do” verbs (do, does, did).
7. Progressive Form
(use “being verbs”)
Example Verb Tense
I shall be going.
shall – future tense
be – being verb
Future progressive
I have been going.
have – present perfect
been – being verb
Present perfect progressive
I had been going.
had – past perfect
been – being verb
Past perfect progressive

will/shall have – future perfect
been – being verb
Future perfect progressive
8. Emphatic Form
(use “do” verbs – do, does, did)
Example Verb Tense
I did go.
did – past form of do
Past emphatic
I do go.
do – present form of do.
Present emphatic
Remember – emphatic only
applies with the present and
past.
9. Why?
Present indicates an action occurring now.
Past indicates an action that has already
occurred.
Future indicates an action that will (or shall)
occur.
10. Why Perfect?
A perfect tense is typically used to describe an ongoing action
completed (e.g. “perfect”):
• Present perfect – action begun in the past and is now
completed
• Corey has completed his science project.
• Past perfect – action that was completed before another
past action
• Mrs. Stone had already bought the gifts before the sale
started.
• Future perfect – action that will be completed before
another future action
• He will have visited all the major cities before he returns.
