Today, we will review the past perfect tense, but let’s look at the form for the perfect tense.

The perfect tense follows this format when we use it:  Have + Past Participle. Since we are studying the past perfect, you need to change the auxiliary verb (have) into past tense (had).

Positive Negative Question
