Why these changes were made: - Added “my” before “midterm exams” for natural possessive form. // - Changed “in this week” to “this week” — no preposition needed with time expressions like this. - Combined the sentence about the exam for smoother flow. // - Added “to” after “listen carefully” because it’s required before the object of listening. // - Changed “a lot of sounds” to “many” to sound more natural and concise. // - Minor punctuation adjustments for better readability.
