Voice can be active or passive.Note 1:
The term can also be used to mean ‘student voice’ or ‘academic voice’ where it means the individual voice of the writer, not a description of the verb
or tense.Note 2:
The passive voice is used in academic writing as it is more formal, avoiding the first person form of the verb
, which gives an impression of subjectivity.Note 3:
The passive voice can be used in any tense.
