KNOW WHEN TO USE THE PAST WITH THE PRESENT
USING THE PAST WITH THE PRESENT
1. If you see a sentence with one verb in the past and one verb in the present, the
sentence is probably incorrect.
2. However, it is possible for a correct sentence to have both past and present together.
3. If you see the past and present together, you most check the meaning to determine
whether or not the sentence is correct.
I understand that you were happy.
