Each student secretly writes down one interesting, unusual, or memorable experience on a piece of paper. It can be related to their personal life, traveling, work, or something unexpected. Examples: - I have helped an animal give birth. - I have gotten lost in another city. - I have eaten something really unusual. - I have met a famous person. - I have worked for more than 20 hours without sleeping. Teacher collects and mixes the papers. Teacher reads each experience aloud. After hearing an experience, students must discover who wrote it by interviewing classmates to identify the person. For example, if the paper says: "I have helped an animal give birth." Students might ask: - Have you ever worked on a farm? - Have you helped deliver puppies? - Have you worked with large animals? - Have you ever assisted with a difficult birth? Students can also ask additional questions about the experience. Once everyone has been identified, write two examples on the board: - "I have helped an animal give birth." - "I helped an animal give birth last year." Ask: "What's the difference between these two sentences?" Don't explain the answer yet. Tell students they'll investigate it during the lesson.

Give students a short evidence sheet. Evidence: 1. I have treated several emergency patients. 2. She has never worked in a wildlife hospital. 3. Have you ever evaluated a patient with severe trauma? 4. We haven't encountered this complication before. 5. The veterinarian has made several difficult decisions. In pairs, students investigate: - What do these sentences have in common? - What is the auxiliary verb? - What form of the main verb is used? - What changes with he, she, and it? - How do we form questions and negatives? - What do ever and never mean? - Do these sentences tell us exactly when the events happened? Each pair teaches its findings to the other pair. You verify their conclusions and correct misconceptions.

Give students these verbs: treat see make take recommend write respond give evaluate be Pairs complete the table and then create five Present Perfect sentences using the verbs. Challenge: One point for each correct participle and one point for each grammatically accurate sentence.

Students interview one another using these questions: 1. Have you ever treated an animal with a serious fracture? 2. Have you ever responded to an emergency outside your workplace? 3. Have you ever had to make an immediate decision? 4. Have you ever worked with an animal in shock? 5. Have you ever recommended a treatment that an owner refused? 6. Have you ever encountered a toxic substance in a veterinary case? 7. Have you ever had to stabilize a critically ill patient? 8. Have you ever worked with a patient whose prognosis was poor? Encourage complete answers: "Yes, I have." "No, I haven't." "I have never treated that type of emergency." Important: For this first class, keep the emphasis on experience questions. Students may naturally add Simple Past details, but the formal comparison between Present Perfect and Simple Past can be addressed in the next lesson.

Create four categories on the board: Professional Experiences Achievements Personal Experiences Things I Have Never Done Each student writes at least two sentences for every category. Examples: - "I have treated several emergency patients." - "I have traveled to another country." - "I have improved my English pronunciation." - "I have never performed surgery on a horse." Students read their sentences and classmates ask additional Present Perfect questions.

Students work in pairs. One student is a veterinarian applying for a position in a veterinary hospital in the United States. The other is the interviewer. The interviewer must discover the applicant's experience in: - Emergency care - Patient stabilization - Surgical procedures - Client communication - Decision-making - Professional development Sample Questions: - Have you ever stabilized an animal in shock? - Have you worked with emergency patients? - Have you ever had to make a difficult decision? - Have you completed any professional training? - Have you ever explained a serious prognosis to an owner? After 8 minutes, students switch roles. Final Task: Each interviewer presents a three-sentence summary of their partner's professional experience.

Part A – Individual Mini-Assessment Complete the following: 1. She __________ (treat) several emergency patients. 2. I __________ never __________ (see) that type of fracture. 3. __________ you ever __________ (make) a difficult professional decision? 4. The veterinarian __________ (not / work) with that species before. 5. We __________ (respond) to many emergencies this year. Then write: 6. One affirmative Present Perfect sentence about your professional experience. 7. One negative Present Perfect sentence. 8. One Present Perfect question using ever. Part B – Reflection Ask students: - What is one thing you learned today? - What is one mistake you corrected? - What do you still find difficult about Present Perfect?
