What have you done?

你已经做了什么？

A picture-based lesson on the present perfect tense (have/has + past participle). Fifteen illustrations show completed actions: aired, cleaned, opened, sharpened, turned on, listened to, boiled, answered, emptied, asked, typed, washed, walked, painted, dusted. Written exercises A (put 'has' in present-perfect sentences) and B (rewrite imperatives as 'I've already done it / I did it...' pairs) are transcribed from the textbook. Workbook practice covers 'Have you ever been to...' dialogues, 'I've already done it / I did it an hour ago' sentence completion, and open-ended situation questions. Grammar exercises practise answering 'and' questions with present-perfect/past-simple pairs and giving correct replies to observations.
