If you know the answers, hands up quickly, I will invite the quickest one to answer this question.Are you ready? Ok, attention please. My question is :What are the greatest four inventions in ancient China?Ok, Leo is the first one! Please tell us your answer.He answered in Chinese, is he right?Yes, he is right.But do you know how to say these things in English?Let’s look at the PPT. They are powder,printing, compass, and papermaking technology.Now let’s watch a short video to learn something about these four inventions.What do you think about the video? Do you think these inventions are great?Ok, today we will learn some other inventions.Step 2 Pre-listeningNow, let us review the way of reading years first.Please look at the blackboard, how to read these years? (I will write some years on the blackboard)The first one, 1876.How do we read it? Eighteen seventy-six, is it right? Yes, it is right. So,what is the regular of reading these numbers?Yes, we can read the year as two parts. When we read them, we can read the first two numbers, then readthe second two numbers. So take the year“1876” as an example again, we can start with “18”, then read “76”. Are you clear?Ok, very good. Now let do some practice.How to read 1885? Eighteen eighty-five?Yes, it is. What about 1927? Who can have a try?Lily, please have a try. Ok, she said “nineteen twenty-seven”. Is she right? Yes, she is right!“2023”，this one is a bit special. Usually we read it as “two thousand and one”, because there are two zeros in the middle of this number. Please pay more attention to this kind of numbers.Any questions? No questions?Ok, everyone, please turn to page 41. And look at the picture of this unit.What are they in English?Yes, they are computer, car, telephone and TV.So do you know which one was invented first? Which one was invented last?Ok, here I need you guess. And work in pairs, to rank them according to the time when they invented. When you finished, please check the answer with your desk mate by using the conversation structure on the PPT (I will show the following conversation on PPT ). Do you understand? Ok, very good, after that I will choose some groups to tell us their orders.Now, do the pair work. Take your time.A: Can you guess which one of them was invented first?B: I think the … was invented first.A: Which one of them was invented last?B: Well, I think the … was invented last.A: I think the TV was invented before the car.B: Well, I think the TV was invented after the car.Ok, every group has finished. So Xiao Hong, please.Thank you, sit down please.She said the first one is TV, second one is computer, then is telephone, the last one is car.Any different ideas?Ok, Zhang Lei, what is your order? Ok, very good. Sit down please. His answer is a little different with Xiao Hong’s. He believes that TV was invented after telephone. What is your opinions? So, is there anyone who knows when the TV was invented and when the telephone was invented? Ok, it seems no one can tell us the specific time.Now let us listen to the tape and find out the time when they were invented.Step 3 While-listeningI will play this record only once, so you should listen carefully. And check your answers in 1a, and then match the inventions with the years in activity 1b.Are you ready? Ok, listen carefully!Ok, do you get the useful information from this listening?I think most of us have known the time when these inventions were invented.Who wants to tell me the correct answer?Ok, John,please tell me your answer!Ok, his opinion is: telephone was invented in 1876, car was invented in 1885, TV was invented in 1927, computer was invented in 1971. Is he right? Yes, he is right.Ok, excellent. Sit down please.So, we can know that telephone was invented first, car was invented second, TV was invented third, the last invented was computer.Ok, now, I will play the record for the second time. At this time, you should read after the record silently. Are you ready?Ok, let’s begin.Step 4 Post-listeningNow, let’s move on to another section.You are supposed to make a dialogue with your desk mate by using the information in 1b. Let’s look at the dialogue first.The first sentence is a question sentence, one student asks, and the other students answers.
