1 首页 Glad to see you again! Did you have a good time reading the story, the night of the horse I hope you did.
2 目标 In today’s lesson, we will move on to learn more about the present perfect tense. At the end of the lesson, you are expected to know the affirmative, negative and question form of the present perfect tense, understand its meaning and use it in different situations.
3 复习 First, let’s take a quick review of the story by answering the questions. 【练习1分钟】 1. How long were the Trojans and the Greeks at war They were at war for ten years. 2. When did the Trojans celebrate They celebrated at night. 3. When did the six Greek soldiers climb out They climbed out an hour after the square was empty. 4. When had the Greek army returned It had returned when the citizens of Troy were celebrating.
4 时态导入 At the beginning of the story, the captain said, ‘They’ve sailed away.’ and the soldier said, ‘They’ve left their horse.’ The two sentences mean “They have sailed away.” and “They have left their horse.” What tense did the captain and the soldier use 【停顿】They used the present perfect tense. 现在完成时 Can you tell the form of the present perfect tense 【停顿】
5 时态形态 The present perfect tense is formed with have or has plus the past participle form of a verb. When we talk about I, we, you and they, we use have plus the past participle form of a verb. For example, I have sailed away. When we talk about he, she or it, we use has plus the past participle form of a verb. For example, he has left. The negative form of the present perfect tense is have or has not plus the past participle form of a verb. For example, they have not sailed away. It has not left. Here are the examples of the question form of the present perfect tense. Have you sailed away Yes, we have. No, we haven’t. Has she left Yes, she has. No, she hasn’t.
6 时态意思 What’s the meaning of the present perfect tense We can use the present perfect tense to talk about things that happened in the past, but are connected with the present. Think about what the captain and the soldier meant when they used the present perfect tense. 【停顿】They’ve sailed away. It means they sailed away in the past and they are not here now. They’ve left their horse. It means they left their horse in the past and the horse is outside the gate now.
7 时态意思 Now can you talk about the meaning of these sentences 【思考1分钟】 Tom has lost his key. It means he lost his key in the past and he doesn’t have it now. He told me his name, but I’ve forgotten it. It means I forgot his name in the past and I can’t remember it now. I can’t find my bag. Have you seen it It means did you see my bag in the past and do you know where it is now Let’s understand the meanings of have gone to and have been to. 【停顿】 James is on holiday. He has gone to Australia. It means he left for Australia in the past and he is there now or on his way there. Alice is back home now. She has been to Australia. It means she went to Australia in the past and she has now come back.
8 练习 It’s time for you to practise. Finish task one on your worksheet. Let’s start. 【练习1.5分钟】 Let’s check the answers. 1. Sally is still here. She hasn’t gone out. 2. I can’t find my bag. Have you seen it anywhere 3. I sent Joe an email this morning, but he hasn’t replied. 4. Is the meeting still going on, or has it finished 5. My parents are on holiday. They have gone to Italy. 6. You are very late. Where have you been
9 already, just, yet When we use the present perfect tense, sometimes we use adverbs or adverbial phrases. Let’s find out what these adverbs and adverbial phrases mean. The captain asked, ‘Have you had lunch yet ’ The soldier might answer, ‘Yes, I have just had lunch.’ He might answer, ‘Yes, I have already had lunch.’ And he might answer, ‘No, I haven’t had lunch yet.’ In the dialogue, just means a very short time before. The soldier had lunch shortly before the captain asked the question. Already means before now. The soldier had lunch before the captain asked the question. And yet means until now. The captain asked if the soldier had lunch until now. And the soldier didn’t have lunch until the time the captain asked the question. Pay attention: we can use just and already with the present perfect tense in positive sentences. We can use yet in negative sentences and questions.
10 练习 Now, finish task 2 on your worksheet. Read the situations and write sentences with just, already or yet. Let’s start. 【练习1.5分钟】 1. Joe goes out. Five minutes later, the phone rings and the caller says, ‘Can I speak to Joe ’ You say, ‘I’m afraid he has just gone out.’ 2. You are eating in a restaurant. The waiter thinks you have finished and starts to take your plate away. You say, ‘Wait a minute! I haven’t finished yet.’ 3. You plan to watch a movie tonight. You book the tickets online. Later your friend says, ‘Shall I book the tickets ’ You say, ‘No, I have already done it.’ 4. You know that Lisa is looking for a place to live. Perhaps she has been successful. You ask, ‘Lisa, have you found a place to live yet ’
11 for导入 Let’s take a look at this example. The Greeks have tried for ten years to capture our city. We can use the present perfect tense to talk about a period of time that continues from the past until now. So the captain means the Greeks tried to capture the city ten years ago and continued 10 years until now.
12 for, since And the captain could also say, ‘The Greeks have tried to capture our city since ten years ago.’ Can you find the difference between for and since For is used with a period of time, like ten years. Since is used with a point in time, like since ten years ago.
13 ever, never Let’s read one more dialogue. Have you ever been to Greece No, I have never been to Greece. Ever means at any time. So the captain asked, “Have you been to Greece at any time in your life ” Never means not at any time. The soldier hasn’t been to Greece at any time in his life. We usually use ever in questions.
14 练习 Now, finish task 3 on your plete the sentences with ever, never, since or for. Let’s start. 【练习1.5分钟】 Let’s check the answers. Have you travelled a lot, Jane Yes, I’ve been to lots of places. Really Have you ever been to China Yes, I’ve been to China twice. What about India No, I have never visited India. By the way, have you stayed in Australia since 2010 No, I have lived here for nearly twenty years. No wonder you look like a local.
15 产出 We’ve learned so much about the present perfect tense. Now it’s your turn to use it. Write four sentences about yourself.
