When to use passive voice?
Why use passive voice?
Examples
Unscientific

Scientific
The procedure was repeated until there was certainty regarding the results. The problems encountered by the patients were caused by the bacteria.
*-For many verbs, the past participle is the same form as for past tense, but there are many irregular verbs with special forms for past participle. Most dictionaries will identify these.
Verb Examples
Developed by Dr. Charlene Sorenson, Gallaudet University Department of Chemistry, and Dr. Tonya Johnson, Gallaudet University English Department.
