What is the difference in focus?" (One focuses on the past action, the other on the current state). Step 2: Rule Discovery Timeline Activity: Draw timelines on the board. Simple Past: Action finished. Time specified (last month, ago). Present Perfect: Connection to now. Time unspecified or duration (so far, already). Contrast: 1　 He went to China. (He is back or not? We don't know, just stating the past event). 2　 He has been to China. (He has the experience now). 3　 He has gone to China. (He is there now). Step 3: Practice Exercise A & B: Complete conversations. Focus on keywords: ever, never, just, yet. I saw the movie yesterday. VS I have seen the movie so far. Guide students to realize yesterday cuts the connection to now. Step 4: Production Task: Short Passage Fill-in-the-blanks. Example: "Dad ______ (decide) the destination yesterday. He ______ (already/book) the tickets. Last year, we ______ (go) to Beijing, but this time we ______ (choose) Chengdu." Pair Interview: Ask your partner about their trips. Use both tenses. 1　 Where did you go last summer?
