Present Perfect Tense The present perfect tense expresses either an action that took place at an unspecified time in the past, or a condition that began in the past but continues to the present. – They have performed the experiment twice. – Lillian Ogg has lived in the same house since she was born. The present perfect is formed by using the present tense of the helping verb “to have” and adding the past participle of the verb.

Past Perfect Tense The past perfect tense expresses an action that was completed before another activity or event in the past. – They had finished by the time he arrived. – I had called to cancel before she did, but she had not received the message. The past perfect is formed by using the past tense of the helping verb “to have” and adding the past participle of the verb.

Common Tense Errors Students often confuse the present perfect and past perfect tenses. Remember that they convey different meanings! Frequently, students will start a sentence or paragraph in the past tense and switch to the present tense partway through for no reason. These verb tense shifts are confusing for your reader. Be sure that shifts in tense are done for a reason, or fix your writing.

Voice of Verbs When the subject of the sentence is the performer of the action, the verb is in the active voice. – In 1581, Sieur Juvigny invented the flageolet. When the subject of the sentence is the receiver of the action, the verb is in the passive voice. – The flageolet was invented by Sieur Juvigny in 1581.
