Highlight each place where the student writer has introduced borrowed material. This is important research style. Encourage your partner to use a variety of verbs such as the critic maintains, argues, disagrees, concurs, stresses, emphasizes, ignores, underscores, and many, many other descriptive verbs that give the paper depth. Check out the verb tense used. Literary papers are generally written in present tense, technically what would be called historical present tense.
Present tense is best unless the context of a passage absolutely required past tense.
