Take this practice statement: "Students who book in advance may use the recording room on Friday afternoons." A paraphrase could be, "The recording room is available on Friday afternoons to students with an advance booking."
The wording changes, but the group, condition, room, and time remain. "All students can use the room every afternoon" is not a paraphrase because it removes the booking requirement and expands the schedule.
Explain before searching for synonyms
Cover the sentence and tell a partner what it allows someone to do. You may naturally change the structure instead of replacing each word individually. Word-by-word synonym substitution can produce awkward wording or an unintended meaning.
Compare the original with your version using a few questions: Is the same person eligible? Is the time unchanged? Is something permitted, required, or merely possible? Those relationships matter more than achieving a completely different set of words.
For academic or professional work, follow the applicable attribution rules; paraphrasing does not make another person's idea your own. In this language exercise, use the supplied invented statement or your own sentences. Try a second paraphrase for a beginner audience and keep the same restrictions. The skill is flexible, accurate explanation rather than disguising the source or making a limited statement sound more impressive.
