教学过程
Step1:Greetings. Hello, boys and girls. Welcome to English class. Step2: Presentation. 1.I had made an unexpected discovery last weekend. I want to share it with you. But you have to complete my introduction with the correct form of the words in the box. Are you ready 2.Last Saturday after my French course, I decided to drive to the market to buy a meat pie for dinner. As I was heading west, I saw a huge truck in the middle of the road. There had been an accident and there were many police officers around. I turned around and decided to go to a nearby mall. However, I missed the road that led to the mall. Then I saw a restaurant that sold chicken noodles. I went inside and the lady, who was the owner, served me the most delicious bowl of chicken noodles ever. I had made a(n) unexpected discovery! I'm so glad that I canceled my plan to go to the market. Step3: Grammar. Do you understand Please pay attention to these sentences: There had been an accident. I had made an unexpected discovery! Do you know their common point Great! The tense. The past perfect tense. 过去完成时可以表示过去某一时刻或者某一动作之前完成的动作或者呈现的动作。简单说来，就是“过去的过去”。 过去完成时的结构是怎样的呢？主语+had+动词的过去分词+其他。 When she got to school, she realized that she had left her keys at home. 当她到学校时，她意识到她把钥匙忘在家里了。 否定句呢？主语+had+not+动词的过去分词+其他。肯定句的had后直接加not就是否定句咯！ When she got to school, she realized that she had not left her keys at home. 当她到学校时，她意识到她没有把钥匙忘在家里。 一般疑问句呢？只需要提前had就可以啦！ Had she left her keys at home Yes, she had. No, she hadn’t. 接下来，我们一起梳理一下过去完成时的常见用法吧！ 表示过去的过去，常常与when，before或者by引导的短语或者从句连用。 By the time I got up, my parents had left for work. 我起床时，我父母已经动身去上班啦！ Before I got to the bus station, the bus had already left. 在我到达公交车站之前，公交车已经开走了。 常常用于宾语从句之中。 I realized that we had graduated from this school. 我意识到我们已经从这所学校毕业了。 常常体现在上下文中。 I didn’t play basketball with them because I had not finished my homework. 我没有和他们一起去打篮球，因为我还没有完成我的作业。 Step4: Practice. Are you clear Can you try to answer these questions You can have a try. Why didn’t you hand in your science homework Before I could start working on it, I had cook for my little brother. Why didn’t you take a shower this morning By the time I got up, the hot water had been used up. Why did you have to walk home from school By the time I left my school, I had missed the last bus. Well done! Today, we learned about my unexpected discovery and combed the usage and structure of the past perfect tense. Do you understand In fact, life is full of the unexpected. I hope we can all be good at finding beauty in life and find the meaning of life. That is all for today. See you next time!
