Ask the students for some sample sentences. Eg. Millie interviewed Mr Dong last week. Eddie was born four years ago. 二、预习设计、成果展示 用括号中所给单词的适当形式填空。 1. I （buy）the bike two weeks ago. I （have）this bike since the beginning of this month.. I （have）it for two weeks. 2. Great changes （take place）in those villages in the last ten years. 3. How many times you （phone）me these days? you （phone）me this morning? 4. Tom can’t get into the room because he （lost）the key to the door. 5. I （look）for the dictionary everywhere, but I （find not）it yet. 6. － the new programmes （start）yet? －No, they （plan, still） 7. We （live）in Shanghai from 1989 to 1999. We （live）for 10 years. 8. They can’t go with us. They （finish, not）the work yet. 9. You （change not ）your mind, haven’t you? 10.In the past he (be) careless. He often (make) mistakes. 三、小组合作、师生探究 Step 2 Introduction of the present perfect tense 1. We use the present perfect tense to talk about things that started in the past and still have some connection with the present. Eg. She has lived in Nanjing since 1995. Eddie has lived with Millie for four years. 2. Tell students the structure of the verb : have / has + past participle The negative structure : have has not + past participle 3. Tell the students that a few verbs can help them recognize the use of the present perfect tense. Tell them the use of “ for “ and “since”. Give more sample sentences. 4. Explain to students that the present perfect tense can also be used in sentences without the adverbs which determine its definite use. In those cases, students need to understand the function of the action affecting the present, eg. She has arrived. We know that she has arrived some time before now, but we do not know when. The simple past tense is used if we have a fixed time, eg. She arrived this morning. 5. Work through a few more example sentences illustrating the difference between the simple past tense and the present perfect tense. 四、归纳总结、巩固提高 1.what you have learnt? 2. The understanding of the present perfect tense 3.The use of the perfect tense: have/ has +p.p 五、当堂检测、及时反馈 句型转换. 1. We began to learn English three years ago. (同义句) We ________________English ___________three years. 2. The old block has turned into a pretty park. (对划线部分提问) _____ has the old block ______ into? 3. They have got married. （用for two years改写句子） They ______ ______ married for two years. 4. I have felt a bit lonely since I moved into that house. (对划线部分提问) ______ ________ have you ______ a bit lonely? 5. Jim moved out of the house because he felt lonely to live there. (对划线部分提问) ______ ______ Jim move out of the house? 选择填空 ( )1.Mr Green has worked in Zhenjiang since his family to China years ago. A.has moved B.moved C.moves D.move ( )2.It's very to talk him.
