How are you today? I hope you are all full of energy and ready for our English class. Before we start, I want to share a little story with you. Yesterday, I met an old friend on the street. He told me that he had just come back from a trip to a very special museum. It was a museum all about robots. He said he had never seen so many different kinds of robots in one place before. Now, I'm curious. Have any of you ever been to a museum like that, a museum with a unique theme? Raise your hands if you have. (Students raise hands and share their experiences briefly if any) T: That's really interesting. You know, in our daily life, we often talk about things we have or haven't done. And today, we are going to focus on a very important grammar point that helps us express such experiences - the present perfect tense. Step 2: Grammar Focus - Presentation T: First, let's look at the Grammar Focus on page 69. Here, we have a set of sentences that show us how to use the present perfect tense. Let's read them together. (Students read the sentences in Grammar Focus aloud) T: Now, let's analyze these sentences. Look at the first one "Have you ever been to a science museum?" What structure do you notice? S: It starts with "Have" and then "you" and then "ever been to...". T: Exactly. In the present perfect tense, when we want to ask a question, we use "Have/Has + subject + past participle". For the first - person and second - person singular and plural (I, you, we, they), we use "have". For the third - person singular (he, she, it), we use "has". Now, what about the answer "Yes, I have. I've been to the National Science Museum." Can you find the past participle in this answer? S: "been" T: Right. "Been" is the past participle of the verb "be". The present perfect tense is formed by using "have/has" plus the past participle of the main verb. This tense is used to talk about an action that started in the past and has a connection to the present. For example, when you say "I have been to the library", it means that at some time in the past you went to the library, and this experience is relevant now. Maybe you borrowed a book there, or you learned something new. Another example, look at the sentence "She has visited her grandparents." When did she visit her grandparents? S: In the past. T: Correct. But we don't know exactly when. The important thing is that this action of visiting her grandparents has an impact on the present situation. Maybe she brought back some stories from her grandparents, or she is feeling happy because of the visit. Now, let's look at the negative form. "I have never been to a water park." How do we form the negative in the present perfect tense? S: We use "have/has + not + past participle". T: Very good. "Have not" can be contracted to "haven't", and "has not" can be contracted to "hasn't". So, if we want to say "He has not seen that movie", we can also say "He hasn't seen that movie". Now, let's practice reading these sentences again, but this time, pay more attention to the pronunciation of "have", "has", "haven't", and "hasn't". (Students read the sentences again) Step 3: Grammar Explanation - Past Participles T: Now, we know that the present perfect tense uses the past participle of the verb. But how do we form the past participle? There are two main types of verbs - regular verbs and irregular verbs. For regular verbs, we usually just add - ed to the base form of the verb. For example, the base form of the verb "walk" is "walk", and its past participle is "walked". Read after me, "walk - walked". Ss: walk - walked. T: Another example, "play". What's its past participle? S: played. T: Right. "play - played". Now, let's practice a few more. "clean" S: clean - cleaned. T: "visit" S: visit - visited. T: But for irregular verbs, it's a bit more complicated. We need to memorize their past participle forms because they don't follow the - ed rule. For example, the verb "go". Its past participle is "been", not "goed". We say "I have been to Beijing", not "I have goed to Beijing". Another common irregular verb is "see". Its past participle is "seen". We say "She has seen that movie", not "She has seed that movie". Now, I'll give you a list of some common irregular verbs on the screen. Let's read them together. (Show a list of common irregular verbs and their past participles on the screen and students read them) T: You need to remember these irregular past participles. It's very important for using the present perfect tense correctly. Now, let's do a little exercise. I'll say a verb, and you tell me its past participle. If it's a regular verb, add - ed. If it's an irregular verb, give the correct irregular form. Are you ready? "look" S: looked. T: "eat" S: eaten. T: "watch" S: watched. T: "write" S: written. T: Good job. Now, let's move on to more practice with the present perfect tense. Step 4: Practice - 3a T: Look at Activity 3a on page 69. Here, we have a conversation between two people, Eric and Carol. Eric is asking Carol questions about the places she has been to using the present perfect tense. First, let's read the conversation silently and try to understand it. (Students read the conversation silently) T: Now, let's fill in the blanks together. In the first question, Eric asks "____ you ever ____ to a history museum?" What words should we use to fill in the blanks? S: Have; been. T: Right. Because it's a question in the present perfect tense with the subject "you", so we use "have", and the past participle of "be" is "been". Now, what about Carol's answer? "Yes, I . I ____ to the National History Museum last year." S: have; went. T: Wait a minute. Is "went" correct here? Remember, we are using the present perfect tense in the answer. What should we use instead? S: have been. T: Exactly. The complete answer should be "Yes, I have. I have been to the National History Museum last year." Now, let's continue with the second question. Eric asks " you ever ____ to an art museum?" S: Have; been. T: And Carol's answer? "Yes, I ____. I ____ to the art museum in our city." S: have; have been. T: Very good. Now, let's read the completed conversation aloud together. Pay attention to the intonation and the correct use of the present perfect tense. (Students read the conversation aloud) T: Well done. Now, I want you to work with your partners. Practice this conversation, but change the places. You can choose any places you like, such as a zoo, a park, a library, etc. One person asks questions using the present perfect tense, and the other person answers. Then switch roles. Start now. (Students practice the conversation with their partners) T: Okay, time's up. Who wants to come to the front and show us your conversation? (Some pairs come to the front and perform their conversations) T: Great job, everyone. You all did very well in using the present perfect tense to talk about the places you have been to. Step 5: Practice - 3b T: Now, let's move on to Activity 3b. In this activity, we need to make sentences using the words given and the present perfect tense. First, look at the example. "I / buy / a new camera" The sentence should be "I have bought a new camera." Now, let's do the first one together. "I / not / see / the movie" How should we make this sentence? S: I haven't seen the movie. T: Perfect. Now, you do the rest by yourself. Write the sentences in your notebooks. (Students write the sentences) T: Okay, let's check the answers. For the second one "she / visit / her grandparents", what's your sentence? S: She has visited her grandparents. T: Right. Third one "we / not / decide / where to go on vacation" S: We haven't decided where to go on vacation. T: Good. Fourth one "he / read / that interesting book" S: He has read that interesting book. T: And the last one "they / not / clean / their room" S: They haven't cleaned their room. T: Well done. You all made the sentences correctly. Now, I want you to share one of your sentences with your partner and ask for more details. For example, if you made the sentence "I have bought a new camera", your partner can ask "When did you buy it? What kind of camera is it?" etc. Start now. (Students share their sentences and ask for details) T: Time's up. I hope you all had good conversations with your partners. Through this activity, you have further practiced using the present perfect tense to talk about things you have or haven't done. Step 6: Practice - 4a T: Look at Activity 4a on page 70. Here, we have some sentences, and we need to circle the correct words to complete them. First, let's look at the first sentence "I ____ (have been / has been) to the zoo many times." Which one should we choose? S: have been. T: Why? S: Because the subject is "I", and for "I", we use "have" in the present perfect tense. T: Right. Now, let's do the second sentence together. "My father ____ (has never been / have never been) to a water park." S: has never been. T: Good. Because the subject is "My father", which is the third - person singular, so we use "has". Now, you do the rest of the sentences by yourself. Circle the correct words. (Students circle the words) T: Let's check the answers. For the third sentence "____ (Have / Has) you ever ____ (eaten / ate) Italian food?" S: Have; eaten. T: Fourth sentence "My friends ____ (has visited / have visited) the Great Wall." S: have visited. T: And the last one "____ (Has / Have) she ever ____ (gone / went) to an amusement park?" S: Has; gone. T: Well done. You all chose the correct words. This activity helps you practice choosing the correct form of "have/has" according to the subject and also using the correct past participle. Now, let's move on to a more challenging activity. Step 7: Practice - 4b T: In Activity 4b, we need to complete the questions and answers with the correct form of the verbs in brackets. First, let's look at the example. "A: Have you ever been (be) to a science museum? B: Yes, I have. I have been (be) to the National Science Museum." Now, let's do the first one together. "A: ____ you ever ____ (see) a movie in an IMAX theater? B: Yes, I ____. I ____ (see) one last weekend." S: Have; seen; have; saw. T: Wait, for the second blank in B's answer, should we use "saw"? Remember, we are using the present perfect tense. What should we use? S: have seen. T: Right. So the complete answer for B should be "Yes, I have. I have seen one last weekend." Now, you do the rest of the questions and answers in your notebooks. (Students complete the questions and answers) T: Let's check the answers. For the second one "A: ____ he ever ____ (visit) the space museum? B: No, he ____. He ____ (want) to go there next year." S: Has; visited; hasn't; wants. T: Third one "A: ____ they ever ____ (take) the subway to school? B: Yes, they ____. They ____ (take) the subway yesterday." S: Have; taken; have; took. But for the last blank, it should be "have taken" because we are using the present perfect tense to answer the question. T: Good catch. You are very careful. Now, the fourth one "A: ____ she ever ____ (eat) Japanese food? B: Yes, she ____. She ____ (eat) it three times." S: Has; eaten; has; has eaten. T: And the last one "A: ____ you ever ____ (go) to an aquarium? B: No, I ____. But I ____ (go) to the zoo many times." S: Have; gone; haven't; have been. T: Well done. You all completed the questions and answers correctly. This activity really tests your understanding and use of the present perfect tense. Step 8: Practice - 4c T: Now, for our last activity in class, Activity 4c. I want you to work in groups of four. Each group member should write down three things they have never done. For example, "I have never ridden a horse", "I have never climbed a mountain", "I have never cooked a big meal". Then, take turns to ask each other questions using the present perfect tense to find out who in the group has done these things. For example, if you wrote "I have never ridden a horse", you can ask your group members "Have you ever ridden a horse?" If someone says "Yes, I have", then they can share their experience. If everyone says "No", then you can mark it as something that no one in the group has done. After that, each group should choose one of the things that no one in the group has done and share it with the whole class. Are you clear about the task? Ss: Yes. T: Okay, start now. (Students work in groups) T: Time's up. Now, each group, please share one thing that no one in your group has done. (Each group shares their result) T: That's really interesting. Through this activity, you not only practiced using the present perfect tense but also got to know more about your classmates. Step 9: Summary T: Today, we focused on the present perfect tense. We learned how to form it, how to use it to ask questions, give answers, and make statements. We also practiced using regular and irregular past participles. Remember, the present perfect tense is used to talk about past actions that have a connection to the present. Keep practicing using this tense in your daily life, and you will get better and better at it. Step 10: Homework T: For today's homework, first, review all the grammar points and exercises we did in class. Make sure you fully understand the present perfect tense. Second, write a short passage about your experiences. You can talk about the places you have been to, the things you have done, or the things you have never done. Use at least five sentences with the present perfect tense. Third, make a list of 10 irregular verbs and their past participles and memorize them. Are there any questions? Ss: No. T: Okay. That's all for today's class. Have a great day! 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
